Starting - Your starting point. Where you begin. - Activities characteristic of the initial search for information - Looking for information in a new area or topic 2. Chaining - Going to the sources of the article to find more information - backward chaining - There is also forward chaining - Searching by following citation connections between materials 3. Differentiating - keeping focused - relevance - Using differences between sources as filters on the nature and quality of the material examined - Selecting information sources based on their orientation and the intended audience 4. Monitoring - Maintaining awareness of developments in a field through the monitoring of particular sources - continuous monitoring of developments in a field of study. 5. Extracting - Finding the information within an article and extracting what you need and figuring out what you would use (6). Browsing - A more broad look at the sources. More general. - semi-directed searching in an area of potential interest Surfing Where are we now? > Information behavior - Information seeking * Searching * Surfing * Encountering Surfing: Browsing through a source of information, just to see what it has, with no particular information need in mind.

Also called: Compare/Match The major issues: * The highly subjective nature of relevance judgment * The levels of relevance * Factors affecting relevance Information Use The outcome of information seeking May take various forms: - Acting on information - Changing state of knowledge (making new sense) - Confirming what one already knows Information Giving > Information behavior - Information seeking - Information evaluating - Information use - Information giving Information Giving The act of disseminating messages Triggers for giving: - A user asks for information directly - A user raises a topic about which the giver has information - A user describes his/her situation to the giver who has information that can help看 - A user behaves (or shows signs) in a certain way that prompts the giver to give information that will help看 - The giver expects to receive needed information in return Strategies for giving: - Tailoring complete information to the attributes of a particular need看 - Planting a nugget (giving in anticipation of a situation)看 - Pushing, or, making a case for the need of information看 - Presenting information and asking for feedback <<<< WEB SITE EVALUATION >>>> Purpose of Evaluation > To understand the Web site better and how it can be user > To decide who will benefit most from it > To improve it > To get ideas about a similar product Attributes for the Evaluation of a Web Site > Purpose and intended audience > Authority - Nature of the domain (.com, .gov, etc..) - Who/What is the site about and who/what organization has compiled it - Inclusion of advertisements > Documentation - Ways to get help - Ways to learn about advanced features > Format - Layout - Fonts - Effects (blinking, sound, animation, others) - Size - Number of graphics > Access and organization: - Navigation methods - Search features - Links - Categories - Language options > Quality of Information - Accuracy - Completeness - Language - Who determines content? - Who creates the content? > Quality of Services - Updating - Other services > Privacy - Is registration required? - Privacy policy > Cost - Any fees for registration? *** Assignments *** Go out and observe within a context information behavior.
