Abstract: We present a soft structured genetic algorithm (s/sup 2/GA) that inherits all theadvantages of its crisp (non-fuzzy) counterpart (sGA), but possesses severaladditional unique features compared to the sGA and other GA based techniques. Weoutline several strengths of the s/sup 2/GA approach with regard to severalemerging problems, such as its ability to address the scalability issue in a veryeloquent manner for most data and Web mining problems. We also illustrate the useif s/sup 2/GA for multimodal optimization by using it within a Deterministic Crowdingframework, when used to find an unknown number of clusters underlying a data setEven though the proposed techniques inherit as legacy from the GA an almostunlimited number of different applications in all areas of science and engineering, wefocus on an application of vital importance in today's networked environment-thatof analyzing usage patterns on Web sites.

Abstract: Information retrieval support systems (IRSS) are designed with the objective toprovide the necessary utilities, tools, and languages that support a user to performvarious tasks in finding useful information and knowledge. While existing informationretrieval systems (IRS) focus on the search and browsing functionalities, an IRSSfocuses on the supporting functionalities. IRSS are more flexible and combine thefunctionalities of IRS, Web browser and Web search engines. One objective of thepaper is to demonstrate the needs for, and the potential benefits of, moving fromIRS to IRSS. On the one hand, IRSS is an emerging important research topic, andon the other hand, there is a lack of a systematic study on the topic. Anotherobjective of the paper is to present a framework for IRSS by drawing results fromdecision support systems (DSS) and intelligent systems. Basic issues of IRSS arediscussed, and basic components of an IRSS, as well as its functionalities, arestudied

Abstract: Content-aware request processing enables the intelligent routing and requestprocessing inside a cluster to provide the QoS (quality of service) requirements fordifferent types of content and to improve the overall cluster performance. ASTREAMS-based TCP/IP implementation in HP-UX 11.0 provides a convenientframework to design a library of new STREAMS modules to support content-awarerequest distribution and differentiation inside a cluster. The proposed modules takeinto account the specifics of different cluster architectures and workloadcharacteristics. These modules are designed as dynamically loadable modules, andno changes are made to the existing TCP/IP code. The proposed design has thefollowing advantages: flexibility (new modules may be loaded and unloadeddynamically, without node function interruption) and modularity (the proposedmodules may be ported to other operating systems with minimal effort; moreimportantly, the proposed STREAMS modules can be easily integrated and deployedinto commercial operating systems, so that end-users may take advantage of thesesolutions much sooner)

Abstract: This paper details the design of a one-dimensional interface element, the“Collated Path” an effort to create a very, light-weight informationmanipulation tool that could be used within a user's own dataset (e.g. their historylist), which could then be used in combination with other searches. It is optimizedto present views of the Semantic Web useful for everyday applications. Emphasiswas placed on creating a tool with Simple elements that could be combined tocreate sophisticated views. Whereas existing Web information tools such asbrowser history and search tools like Sherlock present a limited search/retrieveview, the Collated Path creates a view that encourages the interaction andtangibility of such data enabling effective integration into the workspace. Themodel uses the metaphor of “pages”, representing Web resources,which are “collated” in two variables according to some retrieved orgenerated values, such as time accessed, popularity, or relevance to search terms.In addition, the design is general enough to accept values from an RDF model, theW3C's metadata standard for the Web. The conceptual framework is not restrictedto Web pages, but the “page” metaphor connects the concept withprevious research that have promoted document piles, and other visualizationmethods, while giving it a more grounded basis for discussion

Abstract: In recent years, Internet users have been able to benefit from the increasedamount of information in the World Wide Web (WWW) space, However. informationretrieval efficiency has decreased because of the increasingly complicated WWW. Afundamental solution has not been achieved, though the information retrievalefficiency has been improved by browsing support tools such as the WebInformation Access System (WIAS). Web sites must be improved to achieve afundamental solution. In this paper, we rate Web sites and clarify the problemsusing Web site rating agent KAGAMI (Japanese for "mirror") and present an index forWeb site improvement. This system autonomously collects data using a Web robotand rates sites using the site structure based on the WIAS framework. Additionally,this system generates a report by various visualization and supports tor improvingthe Web site rating by this system

We focus on twoestablished approaches to knowledge management systems-namely superimposedinformation as well as domain ontologies. We also focus on problems arising withWeb content management systems. Since the underlying abstract model of topicmaps provides a high degree of power and flexibility, they can be used to combinethese approaches. Moreover, topic maps offer a framework supporting theevolutionary construction of computer-based organizational memories. Thepresented system architectures have been developed in cooperation with one ofthe largest Internet sites in Austria as well as with an international lawyer's office

Abstract: A radiologist often needs to reference relevant prior images of the same patient forconfirmation or comparison purposes. To effectively support such needs, wedeveloped a knowledge-based patient image pre-fetching system, addressingseveral challenging requirements that included representation and learning of imagereference heuristics and management of data-intensive knowledge inferencing. Thesystem demands an extensible and maintainable architecture design that is capableof effectively adapting to a dynamic environment characterized by heterogeneousand autonomous data-source systems. We developed a synthesizedobject-oriented entity-relationship model that is appropriate for representingradiologists' prior image reference heuristics. We detail the system architecture anddesign of the image pre-fetching system. Our design is based on aclient-mediator-server framework that is capable of coping with a dynamicenvironment. To adapt to changes in prior image reference heuristics, ID3-basedmulti-decision-tree induction and CN2-based multi-decision induction learningtechniques were developed and evaluated. We examined effects of thepre-fetching system on radiologists' examination readings. Preliminary results showthat the knowledge-based patient image pre-fetching system more accuratelysupports patient prior image reference needs than the current practice adopted atthe study site and that radiologists may become more efficient, consultativelyeffective and better satisfied when supported by the pre-fetching system thanwhen relying on the study site's existing pre-fetching practice

Abstract: Deals with the implementation of a logical model of information retrieval.Specifically, we present algorithms for document ranking within the belief revisionframework. Therefore, the logical model that stands on the basis of our proposalcan be efficiently implemented within realistic systems. Besides the inherentadvantages introduced by logic, the expressiveness is extended with respect toclassical systems because documents are represented as unrestricted propositionalformulas. As well as representing classical vectors, the model can deal with partialdescriptions of documents. Scenarios that can benefit from these more expressiverepresentations are discussed

Abstract: In mobile multimedia systems, the mobility of users, devices, and informationproduces new challenges for processing globally distributed information. We focusour attention on new strategies for the adaptation and integration of databasetechniques regarding the management of multimedia data types at the particularconditions of mobile infrastructures. We believe that object-relational databasesystems, e.g. Informix are ideal repositories on the stationary server side for nextgeneration multimedia applications, especially in internetworked LAN or WANenvironments. The basic idea of this paper is the integration of object-relationaldatabase technology in a Mobility Information Center (MIC) as a framework whichfaces the common problems of mobile computing like limited bandwidth, endsystems with limited resources as well as the problems in the context of multimediadata access and interaction. The major aim is to optimize the mobile data exchangeby using content based information retrieval and reduction methods as well asmedia specific queries within the database system in order to reduce the amount ofdata to be transferred. All these methods are influenced by contexts like localresources, available communication channels, and user preferences

Abstract: The management and retrieval of Web data has received significant attention.Among the various approaches, systems have been proposed whose main goal is toprovide a framework to integrate different and heterogeneous information sourcesinto a common domain model. The Web-At-A-Glance (WAG) system falls into thiscategory, its key characteristic being that instead of requiring an explicitdescription of the sources, it attempts to semi-automatically classify theinformation gathered from various sites based on the conceptual model of thedomain of interest. The initial WAG prototype dealt exclusively with“standard” Web pages, which typically are HTML or XML documentsand present non- or semi-structured information, and they vary widely in theirmeans of presenting information to the user. We present the extension of the WAGsystem to deal with form pages. In particular, we describe how the systemsemiautomatically first extracts a conceptual schema for the form page, and thenfills and submits the form in consequence of a user query expressed on the domainconceptual schema

Abstract: Many intelligent retrieval approaches have been studied to bridge the terminologicalgap existing between the way in which users specify their information needs andthe way in which queries are expressed. One of the approaches, called RUBRIC(RUle-Based Retrieval of Information by Computer), uses production rules tocapture user query concepts (or topics). A set of related production rules isrepresented as an AND/OR tree, called a rule-based tree. One of the main problemsin this approach is how to construct such rules that can capture user queryconcepts. This paper provides a logical framework that is semantically essential todefining the rules for the user query concepts, and proposes a way to automaticallyconstruct rule-based trees from typical thesauri. Experiments performed on smallcollections with a domain-specific thesaurus show that the automaticallyconstructed rules are more effective than hand-made rules in terms of precision

Abstract: Information overload in modern electronic life is an inevitable problem. It is moredifficult for users to find information that they need. For resolving this problem, wepresent the framework design and implementation issues of an image retrievalsystem called IIRS with the capability of user adaptation. Even though muchresearch has been performed on the development of efficient image retrievalengines, most of this has focused on the performance of the system, not thefriendliness and efficiency of the user interface. The satisfaction of users is at leastas important as the functionality and performance in image retrieval systems. Anintelligent user interface adaptation method enables IIRS to be more intelligent,natural and efficient. We address the adaptation method that consists of a decisiontree and backpropagation neural network. They have been employed for long-termand short-term adaptations respectively. Experimental results show that theautomatic adaptation method can improve the performance of the IIRS

Abstract: Relational databases and Datalog view each attribute as indivisible. This view,though useful in several applications, does not provide a suitable databaseparadigm for use in genetic, multimedia or scientific databases. Data in theseapplications are unstructured; querying on sub-strings of attribute values is oftennecessary. Moreover due to imprecision and incompleteness in the data,approximate reasoning also becomes indispensable. Our aim is to view strings asdatabase objects that can be compared, divided, subsumed, interpreted andapproximated. Allowing such operations on strings enriches the semantics andincreases the expressive power of database languages. We develop an extension tothe relational algebra, augmenting it with the concept of a string expression with arich structure of string variables, mapping functions, interpreted string operationsand approximate evaluations. We study properties of such expressions and showthat many of the well-known properties of relational algebra hold in the extension.We also discuss an extension to Datalog(String) and an implementation of aprototype system called S-log. S-log integrates pattern matching in Datalogframework. We contend that string oriented database systems would be useful inapplications that require efficient sub-structure analysis, such as aligning DNAstrings using motifs, retrieving and synthesizing iconic images based on content

A unifying framework for compressed patternmatchingKida, T. Shibata, Y. Takeda, M. Shinohara, A. Arikawa, S. Dept. of Inf., Kyushu Univ., Fukuoka;This paper appears in: String Processing and Information RetrievalSymposium, 1999 and International Workshop on Groupware09/22/1999 -09/24/1999, 1999 Location: Cancun , MexicoOn page(s): 89-961999References Cited: 20Number of Pages: xxiii+363INSPEC Accession Number: 6397319

Abstract: We introduce a general framework which is suitable to capture an essence ofcompressed pattern matching according to various dictionary based compressions,and propose a compressed pattern matching algorithm for the framework. The goalis to find all occurrences of a pattern in a text without decompression, which is oneof the most active topics in string matching. Our framework includes suchcompression methods as Lempel-Ziv family, (LZ77, LZSS, LZ78, LZW) (J. Ziv and A.Lempel, 1978), byte-pair encoding, and the static dictionary based method.Technically, our pattern matching algorithm extends that for LZW compressed textpresented by A. Amir et al. (1996)

The storage and querying of 3D objects for thedynamic composition of VRML worldsVakaloudis, A. Theodoulidis, B. Dept. of Comput., Univ. of Manchester Inst. of Sci. & Technol.;This paper appears in: Information Visualization, 1998.

Abstract: The composition of 3D presentations is a complicated procedure partly facilitatedby the introduction of VRML. VRML does not yet support 3D object storage andquerying, thus introducing limitations to object reusability. Presentations have to bebuilt from scratch while the necessary information already exists from previouswork. This paper presents a method to address this issue by providing thefunctionality for (re)composing 3D interactive presentations. The participatingobjects are selected through spatiotemporal criteria. The temporal element isincluded so as to provide a global treatment to virtual (3D space+time) objects.The objects retrieved this way form a repository, and are further transformed inorder to satisfy the requirements of the composed presentation. The entireframework complies with the VRML standard

Abstract: The conventional desktop metaphor is ill equipped to assist modern users who arealready flooded with information. Meanwhile mobile computing is becoming acommon activity of many modern users who are engaged in time critical tasks. Wepropose a new framework called Situated Information Filing and Filtering (SIFF) forinformation management based on a user's situation which consists of sensitivesurroundings such as the location and time and the user activities for modeling theuser's personal information space. In SIFF, the user is not requested to keep inmind explicit information like a file name and its position in the directory structure.The system itself gathers the data about situations and uses them when filing andfiltering the information. Situation dependent Browser, presented in the paper, is anintelligent application that has been developed within SIFF to explore the user'sinformation space. It provides the user with the effective visual interaction on thebasis of the past situations that he/she is interested in

Abstract: Tools for selective proactive as well as reactive information retrieval, informationextraction, information organization and assimilation, knowledge discovery usingheterogeneous, distributed knowledge and data sources constitute some of the keyenabling technologies for managing the data overload and translating recentadvances in automated data acquisition, digital storage, computers andcommunications into advances in decision support, scientific discovery and relatedapplications. Such distributed knowledge networks (DKN) have to be able toeffectively utilize multiple autonomous, often independently owned and operatedinformation systems. Given the complexity of the such systems and the need forautonomy of the components, multi agent systems, because of their modularity,offer an attractive framework for the design of DKN. In such multi agent systems,satisfactory completion of the tasks at hand depend critically on effectivecommunication and coordination among the agents. The paper describes anapproach to coordination and control of DKN through inter agent negotiation usingthe contract net protocol (CNP). The feasibility of the proposed design isdemonstrated on tasks involving information retrieval and knowledge discoveryusing distributed data and knowledge sources

Abstract: If the field of fuzzy information systems is to grow and mature, it is imperative todefine terms precisely. For the sub-field of information retrieval, we attempt toclarify the definition of some terms and discuss the possible sources of fuzzinesswithin this sub-field. Moreover, we discuss the implications that this has in terms ofdefining flexible information retrieval models and propose an approach to informationretrieval in the framework of possibility theory

Modelling interaction with distributed information. Somuch information and so little timeRoast, C. Comput. Res.

Abstract: The paper describes work investigating the modelling of temporal and real-timerequirements within human computer interaction. One particular focus for this workis the highly interactive tools used to access widely distributed information sourceson the Internet, such as “Mosaic”. We argue that the manner in whichsuch tools accommodate inherent communication delays can significantly influencehow users cope with the mass of information available. By developing a model oftemporal and real-time interaction we are able to express general usabilityrequirements which are applicable in a variety of contexts, and can improve thedesign of interactive tools for accessing information. We propose that the extent towhich delays within interface behaviour hinder effective use can be assessed interms of: (i) the generality of behaviours particular inputs can generate (termedbehavioural resolution), and (ii) the degree to which inputs generate similarfeedback (termed behavioural discrimination). These notions can be defined interms of properties of an abstract model of interaction. In particular we adopt anarchitectural model of interaction consisting of inter-connected processingelements, termed interactors. Within this framework interactive behaviour can bespecified in terms of an event algebra and system delays can be associated withthe cost of communication between interactors. We employ the notions ofbehavioural resolution and discrimination in the analysis of usability problems withinexisting tools and consider the impact of usability issues for the access ofdistributed information in general

Abstract: Management of information to ensure that it is current and available when andwhere needed in appropriate combinations is a challenging problem in informationmanagement. Enterprise-wide computer networks have contributed greatly to thesolution of this problem. However, systematic methodologies are lacking forintegrating information based on the context and need, and the creation andmaintenance of distributed databases in which interesting and useful relationshipsare identified, encoded, and maintained to keep pace with the rapid changes acrossthe entire enterprise. In this paper, we outline the conceptual background of ourresearch concerned with the semantics and timeliness of information, and thedevelopment and use of interfaces that depend on the context. A framework tohelp analyze and integrate information for specific sets of tasks and functions in atimely manner, and present in a form most suitable for the task at hand is underdevelopment. A prototype for the information system is being built

Abstract: The digital revolution is now underway. The use of binary zeros and ones to storedata is increasing at a steady rate. They may represent text, images, pictures,sounds, maps, books, music, instructions, programs, or just about anything elsewhich can be represented digitally. As the sizes of the digital data holdings havecontinued to grow, so too has the need to provide meaningful access to this data.There are a number of efforts now underway to provide such access. In most casesthe efforts have been domain specific and progress in one area has been hard toreplicate in a different domain. Part of this difficulty has been the lack of a generalset of concepts and vocabulary that are sufficiently broad enough to bridge thegaps. The paper presents a general taxonomy of knowledge that is independent ofsubject matter domain. It begins with knowledge as the most general class andthen proceeds to subdivide knowledge into its constituent parts: factualknowledge, procedural knowledge, and judgmental knowledge. Definitions of eachtype of knowledge are given along with examples sufficient to understand eachsubclass. A vocabulary is introduced that provides a means to discuss the topic ina manner independent of a specific problem domain. Understanding of thedifferences between different types or classes of knowledge is necessary if aperson or an organization is to begin to build systems that acquire, organize, store,and retrieve various types of knowledge. The paper concludes with a discussion ofsome tools that are currently available to assist in the building and maintaining of aknowledge resource

Abstract: Security issues are the major roadblock currently preventing greater access todatabases over the Internet. In this paper, we propose a framework for secureaccess to databases by a wide audience over the Internet, using World Wide Webinformation servers, a modified version of the NCSA Mosaic Internet browser androle wrappers (software modules that assign roles to incoming database requests,based on the credentials submitted with the request). We also describe anapplication embodying this framework
