In data science research for social implementation, it is necessary to predict and use future trends from observable data and information. However, because data resulting from market transactions or business activities are based on human decisions, it is difficult to completely reproduce the true phenomenon even with a sophisticated model.
To complement such uncertainties and use them in actual business situations, we need to understand the underlying knowledge and background of the data, although their use will be limited unless we have an opportunity to share that knowledge. Moreover, multifaceted data should be utilized for business innovation, and it is considered indispensable to explore data analysis approaches including prerequisite domain knowledge. In this workshop, we refer to the research field using data domain knowledge for analyzing and modeling data (i.e., data systems science) and discuss various topics in different fields, including social networks, power systems, marketing, sports businesses, data sharing techniques, machine learning, and agent simulations.
This workshop was held successfully at the Bunkyo School Building, Tokyo Campus, University of Tsukuba, from January 21 to 22, 2020. During this period, three keynote speeches were given by Professor Ali Jadbabaie, Associate Director of the Institute for Data, Systems, and Society (IDSS), Professor Peko Hosoi, Associate Dean of the Engineering School, and Professor Dean Eckles, the Sloan Business School, Massachusetts Institute of Technology (MIT). Professors Osawa, Toriumi, and Tanaka from the Graduate School of Engineering, the University of Tokyo, also gave invited lectures. The workshop also included speakers from the University of Tsukuba: Yamada, Ban, and Kurahashi from the Faculty of Business Sciences, Sato and Sano from the Faculty of Engineering, Information, and Systems, and Takahashi from the Faculty of Health and Sport Sciences. There was a lively debate during the two- day presentation and corresponding Q&A session that allowed us to recognize important themes in business science research and to continue further interactions.

Opening Remarks /
Yuji Yamada / , Dean of Faculty of Business Sciences, University of Tsukuba
Welcome to the Myogadani School Building of University of Tsukuba, Tokyo Campus. On behalf of all the faculty members and staff of the Tokyo campus, I can say it is our pleasure to host the 1st MIT-Tsukuba Joint-Workshop on Data Systems Science towards Social and Business Innovations. My name is Yuji Yamada. I am the dean of the Faculty of Business Sciences, and in charge of the facultys general research planning and affairs. I hope you enjoy your visit here today.
Before starting the workshop, I would like to introduce the University of Tsukuba and the Faculty of Business Sciences briefly. The main campus of the University of Tsukuba is located in the Tsukuba Science City in Ibaraki Prefecture, which is about 90 min north from here by train. It was founded in 1973, due to the relocation of its antecedent, the Tokyo University of Education, to the Tsukuba area, as part of the new concept of a comprehensive university in Japan to be established under a countrywide university reform plan. The University of Tsukuba covers a wide spectrum of academic fields, from humanities to science, engineering, medicine and physical education, facilitating in-depth research and education. At the same time, it actively pursues interdisciplinary studies which do not fall into conventional academic classifications, and has featured openness with new systems for education and research under a new university administration.
The ancestor of The University of Tsukuba, the Tokyo Higher Normal School, has a long history since its establishment in 1872. It was actually located here, in this place. From its creation to now, three well-known Japanese recipients of the Nobel Prize, Dr. Sin-itiro Tomonaga, Dr. Leo Esaki and Dr. Hideki Shirakawa, have been associated with the university. The Tokyo campus of the University of Tsukuba has a different history. In 1989, after the university relocation to Tsukuba area, we started a graduate school for working people in Tokyo using the facilities of the Tokyo Education University. It was the first attempt among all national universities in Japan to offer evening graduate courses, which is the main platform for the education of working people. Since its opening, the students have not only been active

employees in various fields, but also active students conducting research. The Faculty of Business Sciences is the organization of faculty members who are in charge of Graduate Programs here in Tokyo Campus for systems management, business law, international businesses, and legal studies. We also conduct research in the fields of economics and law to solve the business issues of the “Global Network Age” through scientific perspectives such as the data systems science approach. In this workshop, there are 3 talks from members of our group, Masataka Ban, Setsuya Kurahashi, and myself.
Let me mention that there are a total of 10 faculties at the University of Tsukuba: Humanities and Social Sciences; Business Sciences; Pure and Applied Sciences; Engineering, Information and Systems; Life and Environmental Sciences; Human Sciences; Health and Sport Sciences; Art and Design; Medicine; and Library, Information and Media Sciences. In this workshop, we have 2 talks from the Faculty of Engineering, Information and Systems by Professors Yukie Sano and Mika Sato-Ilic and one from the Faculty of Health and Sport Sciences by Yoshio Takahashi.
Also, special thanks to the invited speakers from the University of Tokyo, Professors Yukio Ohsawa, Kenji Tanaka, and Fujio Toriumi, as well as all those in attendance at this workshop. Finally, we would like to express our sincere thanks to the three plenary speakers from MIT, Professors Dean Eckles, Peko Hosoi, and Ali Jadbabaie. I hope all of you find the discussions at this workshop useful for your future research and enjoy your visit to our Tokyo campus. Thank you for your attention, and now let us start the workshop.

1st Session: Data management and social influence Plenary Talk 1 Dean Eckles “Seeding with limited or costly network information”
When a behavior (e.g., product adoption) may spread through a social network, it can be advantageous to consider network structure when deciding where to seed that behavior. But what if the network is not yet observed and doing so is costly? Some recent empirical work employs methods that only rely on limited network information (e.g., by exploiting the friendship paradox). We consider these and other more sophisticated stochastic seeding strategies that likewise involve sampling information about the network. In the first part, we develop nonparametric methods for empirically evaluating stochastic seeding strategies, including by reusing existing data. This draws on the policy evaluation, dynamic treatment regime, and importance sampling literatures. We show that the proposed estimators and designs can dramatically increase precision while yielding valid inference. We apply our proposed estimators to two field experiments on insurance marketing in rural China and anti-conflict interventions in New Jersey schools. In the second part, we develop novel seeding strategies that come with guarantees about the loss compared with seeding using complete knowledge of the network. These algorithms make a bounded number of queries of the network structure and provide tight approximation guarantees for arbitrary networks. We test our algorithms on empirical network data to quantify the trade-off between the cost of obtaining more refined network information, and the benefit of the added information for guiding improved seeding strategies.

Seeding problems
Influence maximization
Monotone submodular influence functions
Assumes oracle access to the influence function
require explicit and complete knowledge of the network to estimate the influence function using Monte Carlo simulations
Seeding and measuring the network Kim et al. (2015) studied spreading adoption of multivitamins and a water purification method
They measure the social networks for 32 villages in rural Honduras, but contemplate avoiding this costly survey
Randomly assign villages to random, one-hop (i.e., nomination, acquaintance), or max in-degree seeding
from Kim et al. (2015)
One-hop seeding
Proposed for vaccination –
Sample k nodes at random, select a random neighbor of each as a seed
Only requires querying k edges, but doesn’t pool information across them and offers no guarantees
One-hop is importantly stochastic Village 1
One village from Kim et al. (2015). Red is random seed set, green is nomination seed set.
Random targeting
In random targeting, all eligible seed sets are equally likely, so prand i is
characterized by the uniform probabilities
Prand i (Si = s) =
, for all s ∈ Si , i = 1, ... , n, (1)
Notice that this is independent of the graph Gi , the network structure of village i .
Consider one-hop with k = 1. Nodes sized proportional to

Counterfactual policy evaluation: Basic example
Consider some policy that assigns units to treatment iff Xi > c. The mean outcome under this policy is
μπ = 1 N
∑ i

where zπ,i = {Xi > c}. Can estimate this from a randomized experiment with treatment
probabilities pΔ(z|x) > 1 for all z ∈ {0, 1} and x ∈ X.

B denote expectation over Si ∼ pi A and Si ∼ pi
B, respectively.
Superpopulation version:
Notice that τsp can be written as
τsp = EΔ
[ pA(S)− pB(S)
pΔ(S) y(S) .
Design and target distributions Bernoulli design: Zi ∼ Bernoulli(ρ), where ρ ∈ (0, 1) is the treatment
assignment probability, yield a mixture:
Si ∼ ρpA i + (1 − ρ)pB
i .
i (Si = s) + (1 − ρ)PB i (Si = s). (4)
pA i , pB
i , and pΔ i are all completely known, so we know the exact
probabilities corresponding to the observed seed sets. Let si be the observed seed set for village i and let
ai = PA i (Si = si), bi = PB

Re-analysis of Cai et al. (2015)
Experimental setup: Farmer’s insurance in 150 rural Chinese villages. Treatment: Intensive information session about insurance product to
seed set; in first round Response: Fraction of adopters in village
All villages were assigned to a uniform random strategy (prand), but our method actually enables off-policy evaluation, letting us estimate the mean response under both prand and one-hop targeting phop.

Application
Edge queries
Used in sublinear algorithms
Snowball- or RDS-like surveying
Rather than optimizing the influence function on the original graph we do so on a subgraph that is properly sampled from the original graph
Running the spreading process (or something like it) turns out to be a convenient way of sampling graphs for influence maximization

Each query seeds a single node and outputs the identity of the resultant adopters.
The main idea is to use the identity of adopters from independent cascades to seed nodes with optimal approximation guarantees.

Yukie Sano / “Information spreading on social media: Network analysis and simulation”
Information spreading is a crucial issue for society and companies. For example, under emergencies, incorrect and uncertain information may coexist, causing social confusion and sometimes causing serious damage to companies. However, it is generally very difficult to accurately capture the information spreading process. This is because unlike simple spreading processes like HIV, the relationship between the sender and the receiver plays a vital role in information sharing, and makes the spreading process more complicated. In this presentation, we first present the results of a large-scale analysis of the actual data in Japan and China on both true and false information spreading. As a common feature in both countries, the network distance in false information spreading is larger than that of true information. The deviation of the degree distribution in false information spreading networks is smaller than that of the true information. When this feature is used to determine whether the information is false or true from the network topology alone without the content, it is possible to make a determination at an early stage, e.g., five hours after the first re-postings. In addition to network analysis, we also present the results of simulations using virtual scenarios on actual networks. By conducting simulations, it becomes possible to quantitatively discuss how the spreading speed and the scale change in the absence of an influential sender (influencer).

Masataka Ban / “A new inventory classification criterion for retail CRM”
In this research, we propose a new criterion for goods inventory classification to formulate retailers CRM (Customer Relationship Management) strategies. In general, a retail store manager classifies their inventory according to sales volume, average unit cost, annual dollar usage, lead time and so forth. In most cases, they are short-term performance criteria for store profitability, although a retailer using forward CRM strategy needs to evaluate the profitability based on the long-term criterion such as a customer LTV (Life- Time Value). On the other hand, retailers often manage their customers using the so- called RFM metrics, in which “R” denotes purchase recency, “F” purchase frequency, and “M” average monetary amount of purchases. The retail mangers classify the customers by the RFM to identify that customers are highly/lowly profitable, and are ready to churn. Although the RFM strongly depends on data periods, Shumittlein and Peterson (1994, Marketing Science) and their subsequent studies have developed models to estimate customer LTV with a small dependence on the RFM data period. In this work, we construct a model that the customer LTV is regressed on their purchased items, assuming that a profitable customer purchases an item leading to a high performance for store profit. Then, each regression coefficient indicates how much an item does contribute to the customer LTV. Additionally, Shumittleins LTV is calculated by a PLS statistics, where the PLS stands for “Purchase rate”, “Lifetime”, and “Spending per transaction” estimated by the RFM. We investigate how much an item does work for the PLS, and conclude that the model enables us to evaluate the long-term performance of inventory being consistent to the customer LTV. Note that more detailed explanations of the model and empirical studies will be shown in the presentation.

Kenji Tanaka / “A Concept Proposal for Peer-to-Peer Power Exchange for Internet-of-Energy era”
The last decades have seen a huge increase of distributed energy resources. Managing this growing number of intermittent resources requires both a highly interconnected grid as well as distributed storage for balancing supply and demand. As the trend for decentralized infrastructure and hardware continues, so does the need for decentralized control systems and energy management software. We argue that market mechanisms will be key to incentivizing both consumer and prosumer to compromise in electricity trading in order to alleviate peak demands and solving the demand-response problem. However, being able to conceive a secure and decentralized control and billing system adapted to such autonomous, peer-to-peer exchanges is one of the biggest challenges of this century. We propose the applicability of Blockchain as new decentralized tool to enable P2P trading within prosumers of microgrids. To test the feasibility of such a system, we are conducting two real scale microgrid projects with households, shopping centre, and plug-in EVs. The result shows the future potential for harmonizing the gap between demand and supply with this mechanism.

Yuji Yamada / “Creating prediction error insurance market for renewable energy trading”
Predicting future weather conditions is important for electricity industries with renewable energy generators to quote a next-day sales contract (i.e., day-ahead sales contract). If a prediction error exists, the market-monitoring agent has to prepare another power generation resource to immediately compensate for the shortage, resulting in an additional cost for the monitoring agent. In this context, a penalty may be required depending on the size of the prediction error, which may lead to a significant loss for renewable electric power industries. Because the main source of such losses is from prediction errors of weather conditions, they can instead effectively utilize an insurance contract (or a derivative contract) based on prediction errors of weather conditions to hedge against loss caused by prediction errors of power output for renewable energy trading. The objective of this work is to introduce an insurance market based on prediction error weather derivatives, where we focus on solar power energy trades that particularly increased in Japan. To the end, we construct a cross- hedging strategy consisting of solar radiation and temperature derivatives and propose to apply nonparametric regression techniques that enable us to find optimal derivative contracts for solar prediction errors and/or optimal contract volumes of temperature derivatives. It is thought that the development and knowledge sharing of our hedging methods are effective not only for risk management of individual power industries but also for policy decision making as to efficient risk imposition on power industries.

Mika Sato-Ilic / “Statistical Data Science Based on Soft Computing”
Todays vast and complex societal data require adaptable methods to meet the rapidly changing needs of data structures in many areas. Statistical data analysis conventionally played a core role in dealing with any type of data and formed the theoretical foundation for a wide range of data analysis. However, conventional data analysis dependent on statistical methods is not always adequate to handle the often complex data types that make up this data. Soft computing has a key framework to tolerate imprecise and uncertain problems with a robust and computational optimal low-cost solution. This opens the door to a new paradigm based statistical multivariate analysis called soft data analysis that is capable of solving these statistical challenges. In soft data analysis, in which conventional statistical methods and machine learning or data mining methods are combined, we have developed several models that utilize the latent scale captured by soft computing techniques to explain data. While the original scale does not have the capacity to act as the scale for complex data, a scale extracted from the data itself can deal with this data. This presentation focuses on challenging issues of statistical data analysis caused by the new vast and complex data, the general problems of conventional statistical data analysis, how our soft computing based latent- scaled models are related to these issues, and how the models solve the problems with some applications.

Yukio Ohsawa / “Create an Innovators Marketplace with Data Jackets”
Data Jackets are human-made metadata for each dataset, reflecting peoples subjective or potential interests. By visualizing the relevance among DJs, participants in the market of data think and talk about why and how they should combine the corresponding datasets. Even if the owners of data may hesitate to open their data to the public, they can present the DJs in the Innovators Marketplace on Data Jackets that is a platform for innovations. Here, participants communicate to find ideas to combine/use/reuse data or future ollaborators. Furthermore, explicitly or implicitly required data can be searched by the use of tools developed on DJs, which enabled, for example, analogical inventions of data analysis methods. In this talk, the speaker shows some results on the applications of DJs to the explanation of latent dynamics of , consumption market, stock market, earthquakes, and soccer games. Thus, we show a data-mediated platform to cultivate plans in business, science, and daily activities that are now being extended to the redesigning of living and working enviroments.

Fujio Toriumi / “How to design rewarding systems for Consumer Generated Media”
After web 2.0 era, thousands of systems that provide a platform to bridge user to user are developed which called Consumer Generated Media (CGM) such as social news sites, review sites, information sharing sites and video sharing sites. Various incentive systems are implemented in CGM to encourage those content-providers. Both functions of comments and the “like” buttons are well- known systems to reward the providers. Here comes a research question: What kind of incentives encourage to post articles on CGM? In this talk, Ill explain our agent-based model to confirm the effect of incentive systems implemented to CGM.

Result
• To encourage information sharing on CGM: • Comment-Reply systems are effective • Like is effective • “Read mark” is very effective • Effect of monetary rewards are sometime limited
What kind of CGM can survive? • There exists thousands of CGM
• Born and gone • Not all of them are well used
• Do you remember Orkut?
• What is success in CGM? • Values are created by the contents • Contents are provided by users
• Cooperative users are required
How to design CGM
• Users incur costs to generates contents • Most of users avoid paying costs to provide information
• Read Wikipedia > Edit Wikipedia • Incentives to engage in “free-ride” behavior
• CGM can be modeled as Public Goods Game • Two behaviors
• Cooperate = provide information • Defection = Not provide information (only consume information)
• Defection > Cooperation
Cost to cooperate :Benefits :Number of cooperators
Cooperate or Defect • Two choices players can do
• Cooperation, Contributors • Defect, Shirkers
• Opinions of Economists : • Contributors are doomed and vanish quickly if
• In well-mixed populations • random encounters between individuals
• A cooperative society does not emerge! • In a real : people tend to contribute! • Academic challenge
• Why does cooperation evolve?
• Direct reciprocity (Fehr, 2002) • Indirect reciprocity
• Using Tags (Nowak, 2005) • Using Reputations (Ohtsuki, 2007)
2. Selective players (don’t play to all players) • Spatial structure (Helbing, 2010) • Network (Nakamaru, 2005)

• Some CGM has royalty points for cooperators • Get royalty points by posting articles • Ex. TripAdviser
• RQ: Is monetary rewards effect to encourage posting information?
Monetary vs Psychological reward
• No monetary rewards • R
• Monetary rewards • Loyalty points
• These CGM have similar systems • Users can post recipes • Comments to the recipes(reward system) • Replies to the comments (meta-reward system)

Discussion
• Monetary rewards are limited in some cases • Quality is important factor
• Monetary rewards become incentive to post low-quality information
• If there are only peer rewards, no one gives rewards to low quality information providers
• The quality of information in CGM become lower • Users move to another CGM when they can find only
low-quality information • Cooperators who prefer psychological rewards are satisfied
even in non-monetary reward CGM
Result
• RQ : Which kind of rewarding system encourage usage of CGM?
• Meta reward system • Comment-reply system Encourage usage of
CGM • Low-cost reward system
• Like button Encourage usage of CGM • Monetary reward
• Loyalty points for the contribution • Some times fail to encourage usage of CGM
Conclusion
• It is difficult to design CGM • How can we develop CGM with information providers
• CGM can be modeled as PGG • Use agent-based simulation to realize cooperation in PGG
• Three types of rewarding system • Meta reward system • Like or read mark system
• Many CGM have • Good system to encourage cooperation
• Monetary reward system • Fail to keep quality

Setsuya Kurahashi / “Model-based Policy Making: Health policy, Electricity market and Urban dynamics”
Many significant policies of our society and economy are determined by someone day after day. However, most of the plans have been discussed and decided based on past experiences and data. Many of them estimate policy effects by analysing actual phenomena and data using statistical methods. For this method called evidence-based policymaking (EBP), this lecture proposes model-based policymaking (MBP). The MBP is designed with an agent-based model and data science techniques, and it is also called as social simulation. The model-based approach enables to design realistic phenomena as a model and predict the effect on unfolding future events due to hypotheses or activities that are difficult to experiment using computer experiments.In the field of business and sociology, data analysis as an induction method and strategy planning as a deductive method are connected. In the lecture, I will introduce the analyses of health policy for infectious diseases, electricity market and urban dynamics.

5th Session: Sports analytics and management
Plenary Talk 3 Peko Hosoi “Sports in the Age of Data”
In light of recent advances in data collection, sports possess a number of features that make them an ideal testing ground for new analyses and algorithms. In this talk I will describe a few studies that lie at the intersection of sports and data. The first centers on fantasy sports which have experienced a surge in popularity in the past decade. One of the consequences of this recent rapid growth is increased scrutiny surrounding the legal aspects of the games, which typically hinge on the relative roles of skill and chance in the outcome of a competition. While there are many ethical and legal arguments that enter into the debate, the answer to the skill versus chance question is grounded in mathematics. In this talk I will analyze data from daily fantasy competitions and propose a new metric to quantify the relative roles of skill and chance in games and other activities. This metric is applied to FanDuel data and to simulated seasons that are generated using Monte Carlo methods; results from real and simulated data are compared to an analytic approximation which estimates the impact of skill in contests in which players participate in a large number of games. We then apply this metric to professional sports, fantasy sports, cyclocross racing, coin flipping, and mutual fund data to determine the relative placement of all of these activities on a skill-luck spectrum. The second project I will describe is a collaboration with Major League Baseball to determine the physics behind the recent increase in the rate of home runs. In this part of the talk I will enumerate different potential drivers for the observed increase and evaluate the evidence in the data (box score, ball tracking, weather, etc) in support of each theory.

Yoshio Takahashi / “Innovation of Sports by New Technologies and Data Systems Science in Japan”
In the 21st century, the IT industry began to drive the economy in Japan. In the sports world, Rakuten decided to enter professional baseball in 2005, and DeNA acquired the baseball team in 2012. Originally, Japanese sports have spread mainly to club activities as part of school education. Companies also owned sports clubs for employee benefits and advertising, but they did not use them for technology development. This is very different from American sports, which have developed as entertainment business, and in Japan, there was no incentive to introduce new technology into the sports world. Against this background, data analysis for winning the Olympics and world championships was the first to draw attention by the Japan Institute of Sports Sciences. The data analyst who led the national volleyball team to a bronze medal in London Olympics launched the Japan Sports Analysts Association. On the other hand, IT continued to develop in Japan, and as a result of the successful bid for the Tokyo Olympics, the number of companies that disseminated Japans technological capabilities to the world increased in the wake of the Tokyo Olympics. The Sports Agency, which was established in 2015, positions the sports industry as a growth industry and supports sports innovation, the development of new technologies, and data science as a national sports policy. In the presentation, I would like to introduce the use of New Technologies and Data Systems Science in Japanese sports.

Closing Remarks /
Hideo Kigoshi / , Vice President and Executive Director for Research, University of Tsukuba, Japan
I would like to thank all of you for your contributions to this workshop which I believe has been successful in presenting the picture of the current research on Data Systems Science towards Social and Business Innovations. There were five sessions in the two-day workshop, and we have discussed a variety of topics on marketing, social media, networks, electricity market and its risk management, statistical data science, innovators market place, agent-based modeling, sports, and so on. Let me emphasize that we have discussed a variety of topics, because this is actually key to having a workshop focused on data systems science. Data is spread over various fields and in each field, we need specific knowledge on the data. We could analyze the data in our own field, but we expect to develop more sophisticated methodologies by utilizing the ideas used in other fields. This is the reason why have assembled in this workshop. Also, I would like to express my gratitude to all the speakers including the
three plenary speakers from MIT IDSS, professors Dean Eckles, Peko Hosoi, and Ali Jadbabaie. Special thanks to the invited speakers from the University of Tokyo, Professors Yukio Ohsawa, Kenji Tanaka, and Fujio Toriumi as well as the speakers from our group, University of Tsukuba. Let me mention that in the period of FY2018 2020, this workshop has
been supported by Pre-Strategic Initiatives, Research Base-Building program, University of Tsukuba. The adopted project is entitled “Construction of Data Science Research Station toward Market and Open Data Based Business Innovations.” I hope that in the near future, this project will attain excellent research achievements and build a research basis in collaboration with researchers here. I hope and believe that everyone has learned something very important, and
it is evident that we all have shared interests. In addition, and most importantly, I do hope that we have established contacts and made friends who may prove beneficial scientifically as well as personally. With these words, on behalf of the faculty members and research groups of the University of Tsukuba, I thank all of you for these interesting ane pleasant workshop days. Again, thank you very much.

Bachground Objective
In recent years, the framework for market transactions and the mutual use of open data has been rapidly evolving in real business fields. For example, retail electricity liberalization has led to an era in which wholesale electricity is priced according to market principles, and the government is actively releasing open data platforms for utilizing the data in business activities. To analyze such accumulated data and connect it to new strategies, it is necessary to understand both advanced business practices and academic research at the same time. Based on this research center, the Faculty of Business Sciences aims to promote data science research to support business innovations by deepening mutual understanding between business and research in cooperation with the Graduate School of Business Sciences, University of Tsukuba.
