  1. INFO 414 Information Behavior Models of information behavior

  2. Classic IR Model Document Document Representation Query Information Need Match

  3. Berrypicking • Berrypicking focuses is on the sequence of searcher behaviors • Query is evolving • Searchers may use different search strategies in a single query • Implications for design of information systems

  5. Ellis (1989) – Searching Methods • Starting: Looking for information in a new area on on a new topic. • Chaining: Searching by following citation connections between materials. • Differentiating: Selecting information sources based on their orientation and intended audience.

  6. Ellis (1989) – Searching Methods • Monitoring: The continuous monitoring of developments in a field of study • Extracting: Going through a particular source selectively identifying relevant material from that source

  7. Ellis (1989) • Information-seeking patterns of social scientists • Six characteristics: • Starting • Chaining • Browsing • Differentiating • Monitoring • Extracting

  8. Ellis (1989) • Behavioral Model of Information Seeking Diagrammatic presentation suggested by Wilson, 1999

  9. Kuhlthau (1991) • six stages in the information search process • incorporated in three realms • affective - feelings • cognitive - thoughts • physical - actions

  10. Kuhlthau (1991) • Stages • initiation - the first awareness of a lack of knowledge or understanding • selection - identifying the general topic of the approach to be pursued • exploration - investigating information on the general topic, to improve orientation sufficiently to form a focus for resolving the problem

  11. Kuhlthau (1991) • formulation - forming a focus for the information encountered • collection - extends and supports the focus and selects information pertaining specifically to the focus • presentation - completing the search and preparing to present or otherwise use the findings
