Web Evaluation Today:Raising the Bar
![Page 27: Updating Your Digital Toolkit](https://reader035.fdocuments.us/reader035/viewer/2022062814/56816858550346895dde7fce/html5/thumbnails/27.jpg)
Web Evaluation Where we are and how we got here Checklists: what they do and don’t do Raising the bar beyond the basics Using the Social Web in evaluation Active learning applications
![Page 28: Updating Your Digital Toolkit](https://reader035.fdocuments.us/reader035/viewer/2022062814/56816858550346895dde7fce/html5/thumbnails/28.jpg)
One of the basics….What’s in a web address?
Transfer protocol/Domain name/Directory & subdirectory/File name
TP- hpertext https-(http secure) Encrypts all traffic to and from that site
Domain nameName unique to the server where the site is located. Includes domain type and country if outside the US.
![Page 29: Updating Your Digital Toolkit](https://reader035.fdocuments.us/reader035/viewer/2022062814/56816858550346895dde7fce/html5/thumbnails/29.jpg)
Transfer protocol/Domain name/Directory & subdirectory/File name
DirectorySpecific “folder” on the server where this file is found
File nameActual name and information about the file› Markup language used: html, htm, php› Dynamic content: shtml, asp› Format: pdf, docx, jpg, mpeg, mp3
![Page 30: Updating Your Digital Toolkit](https://reader035.fdocuments.us/reader035/viewer/2022062814/56816858550346895dde7fce/html5/thumbnails/30.jpg)
Evaluative Checklists:Pro and Con
Pro› Structured approach to a complex process› Useful reminders of what to look for
Con› Many focus on potential flaws of a site rather
than its strengths› One checklist does not “fit all” types of sites› No substitute for critical investigation geared
to the specific site› Time-consuming and impractical
![Page 31: Updating Your Digital Toolkit](https://reader035.fdocuments.us/reader035/viewer/2022062814/56816858550346895dde7fce/html5/thumbnails/31.jpg)
Raising the bar beyond the basics Berkman, Robert The Skeptical Business Searcher
Medford, NJ: Information Today, 2004
Pushing past superficial generalizations to think critically and deeply about the web site
Domain type is just the beginning of critical evaluation and analysis
Effective evaluation may call for an approach unique to that site

Using the Social Web in EvaluationInfluence Metrics
Many social media services offer data on the sites and topics their users are citing
Mining this data can be a measure of a site’s influence and popularity

Team-based Web Evaluation Learning Goals
› Discern 4 key indicators of a website’s credibility
› Understand the complexity of these indicators by analyzing a given website and responding to questions using a 5-point scale
› As a team, agree to a common answer for each question
› As a team, articulate the rationales for these answers to the entire class

Future Directions in Searching

Is a universal notion of relevancy possible for today’s web searchers?
What are searchers looking for and how do engines enable (or hinder) them?
![Page 49: Updating Your Digital Toolkit](https://reader035.fdocuments.us/reader035/viewer/2022062814/56816858550346895dde7fce/html5/thumbnails/49.jpg)
Modalities of Search“Three Mindsets of Search” - About.com 2011
http://www.advertiseonabout.com/wp-content/uploads/2011/09/3-Mindsets-of-Search-PR.pdf
“Answer me” 48% › Give me exactly what I ask for…
“Educate me” 26%› Broad, contextual understanding, with
multiple perspectives “Inspire me” 28%
› Fun, “browsy” search; Looking for surprises, travel, etc.
![Page 50: Updating Your Digital Toolkit](https://reader035.fdocuments.us/reader035/viewer/2022062814/56816858550346895dde7fce/html5/thumbnails/50.jpg)
Can any single search service based on full-text retrieval satisfy all these modalities, regardless of how many ranking algorithms come into play?
![Page 51: Updating Your Digital Toolkit](https://reader035.fdocuments.us/reader035/viewer/2022062814/56816858550346895dde7fce/html5/thumbnails/51.jpg)
Social networks and Search“Three Mindsets of Search” - About.com 2011
How would you define “an expert”?› 96% include “self-taught “allies with
experience and motivation› 89% include the wisdom of crowds
in social or outside networks› 87% include traditional credentialed
experts

Growing Trends… Social networks as sources for
information and se ranking data Facebook as e-commerce hub (stores
and companies’ fanpages) Content packaged in video and audio Mobile search apps
› May only search for one thing but it does that very well
Development of niche engines for different search modalities (Return of vertical engines?)
