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
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 name Name unique to the server where the site is located. Includes domain type and country if outside the US.
Transfer protocol/Domain name/Directory & subdirectory/File name • Directory Specific “folder” on the server where this file is found • File name Actual name and information about the file • Markup language used: html, htm, php • Dynamic content: shtml, asp • Format: pdf, docx, jpg, mpeg, mp3
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
Raising the bar beyond the basicsBerkman, 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
Degrees of confidence among all domain types • .com Very high • Articles from trusted magazines and other news sources • Archives of public media sites (BBC, NPR, etc.) High • Public-service organizations (many are .org) • Academic scholarly articles
Degrees of confidence • .com Medium • Advocacy groups/special interest sites • News wires • Company-issued white papers • Company home pages Low • Personal pages • Marketing/sales pages • Bloggers I don’t know
Degrees of confidence • .gov Very high • Federal statistics sites • Recognized international organizations High • Federal government information clearinghouses • Governmental public service pages
Degrees of confidence • .gov Medium • State/local public records information • Departmental/agency home pages (may be subject to political pressure) • Embassies/consulates
Degrees of confidence • .edu High • University administration pages • Faculty home pages (publication links, syllabi) • Library guides • Research center findings and reports Medium • Graduate papers Low • Undergraduate papers
Domain Registration • Currently unrestricted: • .com • .info • .net • .org • Currently require proof of eligibility • .edu .coop .mil • .gov .int .museum • .xxx .aero .asia
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 • Wheeler, Emily and Samara Ormundson “Evolution In Source Evaluation: Using Social Media Data” FUMSI Jan. 5, 2010
Influence Attributes within a website • Check for • Self-reported web traffic data • Number of comments (blog) • Intended audience • Audience profile • Incoming links (link:URL in Google)
Sources for Influence Metrics • Alexa • Alexa traffic rank • Sites linking in • Time spent on site • Quantcast • Traffic frequency • Est. monthly US visitors • Audience demographics • Technorati • Authority • YouTube • Views • Star ratings • Comments • Twitter • Followers • Following • TwitterCounter • Twitter rank • Predicted followers in 30 days
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
Subject-focused literature review workspace • http://tinyurl.com/refwhs2 • Students work as individuals • Everyone sees responses and progress • Serves as springboard for discussion • Encourages participation throughout the class • Adaptable to web evaluation assignments

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?
Modalities of Search“Three Mindsets of Search” - About.com 2011http://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.
Can any single search service based on full-text retrieval satisfy all these modalities, regardless of how many ranking algorithms come into play?
