Basic Concepts in HIB Acquiring new lenses to see HIB and a new language to analyze it
Information Need—Definition • Information needs arise whenever individuals find themselves in a situation, and require information to deal with the situation as they see fit.
Information Need—Definition The difference between: • Information want • Information demand • Information need
Information Want • The information a person thinks she or he wants to have to solve an information problem Or: • The information a person believes will solve his or her information problem
Information Demand • The information a person believes he or she can ask for Why should not one ask for what one wants? • One may not know what one wants • One may want to ask for what one think one can get • One feels uncomfortable
Information Need • The information that will solve the person’s information problem How can we know if something is a true information need? • After the fact • Have a “scientific” way to determine
Stages of Need Development (Taylor) • Visceral: A sense of uneasiness • Conscious: Ill-defined area of indecision • Formalized: Describes area in concrete terms, making the need as explicit as possible • Compromised: Need as translated into the system’s language
Stages of Need Development Exercise Please identify the stages of the information need in each of the following quotations on the handout. Time: 5 minutes
Types of Information Needs • By Nature of Expected Answer: • Known item need: The answer that is required is a certain, known item • Subject need: The answer that is required is information on a particular subject, or of a particular kind
Types of Information Needs • By the Generator of the Need: • Self need: A need generated by the person who is looking for answers • Proxy need: A need generated by another person (imposed need)
My Information Need Exercise • Turn to your neighbor and exchange a copy of the completed assignment • Read your neighbor’s assignment and analyze the need described in terms of the characteristics just covered • Discuss with your neighbor what your analysis revealed Time: 5 minutes
Information Behavior • Information seeking • Information evaluating • Information use • Information representing • Information giving
Information Behavior • Information seeking: How an individual goes about obtaining information. • Information evaluating: How users decide if the information they obtained is relevant to their need, that is, if it can resolve their need.
Information Behavior • Information use: The outcome of information seeking. • Information representing: creating surrogates to represent information. • Information giving: The act of disseminating messages.
Information Seeking How an individual goes about obtaining information. Types by level of purpose: • Searching • Surfing • Encountering
Information Seeking Searching: Purposely looking for information to resolve a particular information need. Surfing: Browsing through a source of information, just to see what it has, without a particular information need. Encountering: “Bumping” into information that can resolve a particular information need when doing other things.
Information Seeking—Class Workout • Revisit your neighbor’s assignment and indicate: • What behavior is described (seeking, evaluating, use, giving)? • If seeking, what type (searching, surfing, encountering)? • Discuss with your neighbor what your analysis revealed Time: 3 minutes
Search Strategies Where are we now? • Information behavior • Information seeking • Searching • Search strategies
Search Strategies (Cognitive Work analysis) The five search strategies: • The browsing strategy • The analytical strategy • The empirical strategy • The known site strategy • The similarity strategy
Search Strategies The browsing strategy: Intuitive scanning following leads by association without much planning ahead. The analytical strategy: Explicit consideration of attributes of the information need and of the search system
Search Strategies The empirical strategy: Based on previous experience, using rules and tactics that were successful in the past The known site strategy: Going directly to the place where the information is located
Search Strategies The similarity strategy: Find information based on a previous successful example that is similar to the current need.
Search Strategies Exercise • Revisit your neighbor’s assignment and indicate: • What search strategies were used? • Discuss with your neighbor what your analysis revealed Time: 3 minutes
Searching Methods (Ellis) Where are we now? • Information behavior • Information seeking • Searching • Search strategies • Searching methods
Searching Methods (Ellis) The five searching methods: • Starting • Chaining • Differentiating • Monitoring • Extracting
Searching Methods (Ellis) Starting: Looking for information in a new area or on a new topic. Chaining: Searching by following citation connections between materials. Differentiating: Selecting information sources based on their orientation and the intended audience.
Searching Methods (Ellis) Monitoring: The continuous monitoring of developments in a field of study. Extracting: Going through a particular source selectively identifying relevant material from that source.
Searching Methods Exercise • Revisit your neighbor’s assignment and indicate: • What searching methods were used? • Discuss with your neighbor what your analysis revealed Time: 3 minutes
Surfing Where are we now? • Information behavior • Information seeking • Searching • Surfing • Encountering
Surfing Surfing: Browsing through a source of information, just to see what it has, with no particular information need in mind. Examples: • Reading the daily newspaper • Watching programs on TV • Visiting a bookstore • Surfing the Web Other examples?
Encountering Encountering: “Bumping” into information that can resolve past or future information need. Also called: • Accidental discovery of information • Incidental information acquisition
Encountering Can happen when: • Searching for information to resolve another need • Surfing • Any other activity
Information Evaluating Where are we now? • Information behavior • Information seeking • Information evaluating • Information use • Information giving
Information Evaluating Information Evaluating: Users evaluate information when they decide if it is relevant to their need; that is, if it can resolve their need Also called: Compare/match
Information Evaluating The major issues: • The subjective nature of relevance judgment • The levels of relevance • Factors affecting relevance
Information Surfing, Encountering and Evaluating Exercise • Revisit your neighbor’s assignment and indicate: • Was any surfing or encountering done? • What criteria was used to evaluate the information? • Discuss with your neighbor what your analysis revealed Time: 3 minutes
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 Use Exercise • Revisit your neighbor’s assignment and indicate: • How did your neighbor used the information obtained? • How did it help (or not help) her or him? • Did another information need emerge as a result? • Discuss with your neighbor what your analysis revealed Time: 3 minutes
Information giving Where are we now? • Information behavior • Information seeking • Information evaluating • Information use • Information giving
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
Information giving Triggers for giving: • A user describes his/her situation to the giver who has information that can help • A user behaves (or shows signs) in a certain way that prompts the giver to give information that will help • The giver expects to receive needed information in return
Information giving Strategies for giving: • Tailoring complete information to the attributes of a particular need • Planting a nugget (giving in anticipation of a situation) • Pushing, or, making a case for the need of information • Presenting information and asking for feedback
Information giving exercise • Revisit your neighbor’s assignment and indicate: • Was information giving involved? • If yes, • What triggered it? • What giving strategy was used? • Discuss with your neighbor what your analysis revealed Time: 3 minutes
