1 I. Theories of Information-Seeking Behavior II. Information-Gathering Process by Selected Groups

2 I. Theories of Information-Seeking Behavior

3 activities a person may engage in when identifying his or her own needs for information searching for such information in any way and using or transferring that information (T.D. Wilson 1999) Information behavior

4 Theories of Information-Seeking Behavior nested model of the information behavior, information-seeking behavior, information searching behavior areas dimension of information behavior studied methods purposes and application information- search behavior information-seeking behavior information behavior

5 Theories of Information-Seeking Behavior interactions between information-searcher and information-provider limited to the design of information retrieval (IR) systems models of users in interaction with IR systems (Saracevic, Belkin, Ingwersen) Information-searching behavior

6 Theories of Information-Seeking Behavior Wilson (1981) Dervin (1983, 1996) Ellis (1989); with Cox and Hall (1993) Kuhlthau (1991) Wilson (1996) 5 Models of Information(-Seeking) Behavior

9 Theories of Information-Seeking Behavior Ellis & Kuhlthau: active search mode of information- seeking behavior Dervin: framework for exploring the totality of information behavior (exploration of the context in which information needs arise to the means whereby need is satisfied either through active searching or otherwise) 5 Models of Information(-Seeking) Behavior

10 Theories of Information-Seeking Behavior Wilson’s Model of Information behavior Information user Success Need Information-seeking behavior Information use Satisfaction or non-satisfaction Other people Failure Demands on other information sources Demands on information systems Information exchange Information transfer

11 Theories of Information-Seeking Behavior theories are models of methodologies, rather than a model of a set of activities or a situation case studies of information-seeking behavior (empirical component) are driven by theories and models of methodologies

12 Theories of Information-Seeking Behavior Quantitative methods not appropriate for the study of human behavior (counting of number of visits to libraries, number of personal subscriptions to journals, citation practices) positivist tradition (1940s to 1970s)

13 Theories of Information-Seeking Behavior Qualitative methods appropriate for the study of human behavior (from allied work in related areas that have built robust theoretical frameworks and methodological approaches) emergence of general models of information behavior in the last 10-15 years) post-positivist tradition (from the early 1970s)

14 An Integrated Model of Information- Seeking Behaviors iterative model of information-seeking behavior (series of interactions, learning process by the user, implications for design of IR systems) two-step flow of communication model and the notion of the “gatekeeper” informal transfer of information between individuals (information exchanges)

15 An Integrated Model of Information- Seeking Behaviors uncertainty vs. relevance as focus

16 II. Information-Gathering Process by Selected Groups

17 Information-Gathering by Selected Groups (information needs of four professional groups) Decision-makers Problem-solvers People-centered Self-expression

18 Information Needs of Four Professional Groups politicians, public administrators, judges, managers, supervisors, business people, institution presidents scientists, researchers, engineers, architects, philosophers, planners, statisticians, economists, computer programmers Decision-makers Problem-solvers

19 Information Needs of Four Professional Groups doctors, lawyers, police, firefighters, clergy, information specialists, social workers, teachers actors, musicians, authors, sculptors, composers, photographers, decorators People-centered Self-expression

20 Information Needs of Four Professional Groups sample questions each group might ask What must I know about a subject? What could I know about a subject? What should I know about a subject? What would I like to know about a subject?

21 Information Needs of Four Professional Groups task oriented goal-oriented people-oriented expression-oriented Decision-makers Problem-solvers information need /goal People-centered Self-expression

22 Information Needs of Four Professional Groups human-human and human-machine interaction aggregated / synthesized / capsulated indicators / trends “smoothed out” to eliminate aberrations assistants and other surrogates Decision-makers information modes /resources

23 Information Needs of Four Professional Groups human-human and human-machine interaction factual / quantitative / detailed / specific observations and measurements (data) browsing documents and literature Problem-solvers information modes /resources

24 Information Needs of Four Professional Groups human-human and human-machine interaction “who to see,” “where to go,” “when to do” coping standards and guidelines / laws, rules, regulations “how to use,” “where to find” People-centered information modes /resources

25 Information Needs of Four Professional Groups human-human and human-machine interaction travel / visits dreams observations impressions Self-expression information modes /resources

26 Implications for Information Service, IR System Development R.T. Morris: Toward a User-Centered Information Service. JASIS 45 (1) 1994 forms of delivery resources role of information professionals (intermediaries) and end-users

27 Information-Gathering Process by Selected Groups conceptual models about information held in a subject domain, by a group of users user studies focus on information-seeking behaviors of distinct professional groups because these differences among various user populations determine how they organize information for retrieval

28 Information-Gathering Process by Selected Groups personal information systems (individual’s information handling) public schemes (depend on convention)

29 Information-Gathering Process by Selected Groups user’s motivation in storage and retrieval of text is important in how personal information space is organized

30 Information-Gathering Process by Selected Groups Carol Kuhlthau: The Role of Experience in the Information Search Process of an Early Career Information Worker: Perceptions of Uncertainty, Complexity, Construction, and Sources. JASIS 50(5) 1999 INFORMATION WORKERS / MANAGERS longitudinal study of a securities’ analyst process of information seeking and decision making are intertwined and in recursive interaction

31 Information-Gathering Process by Selected Groups INFORMATION WORKERS / MANAGERS study of sources of information used, and of the process of seeking information sources: information about events and relationships in a company’s outside environment the knowledge of which would assist top management in its task of charting the company’s future action

32 Information-Gathering Process by Selected Groups INFORMATION WORKERS / MANAGERS External Personal External Impersonal Internal Personal Internal Impersonal categories of sources

33 Information-Gathering Process by Selected Groups INFORMATION WORKERS / MANAGERS EP (customers, competitors, government officers, business associates) EI (newspapers, periodicals, broadcast media, conferences, industry and trade association publications and communication) IP (superiors, board members, subordinate managers, staff) II (internal memos, reports and studies, corporate library, and electronic sources)

34 Information-Gathering Process by Selected Groups INFORMATION WORKERS / MANAGERS Internal Channels External Channels Institutional Resources classification of sources (Baldwin and Rice 1997)

35 Information-Gathering Process by Selected Groups INFORMATION WORKERS / MANAGERS Internal Channels (newspapers read, magazines read, personal files maintained, and other securities analysts consulted) External Channels (company contacts, visits to companies, annual meetings/trade shows, research report recipients) Institutional Resources (use of external and internal libraries)

36 INFORMATION WORKERS / MANAGERS environmental scanning viewing nonspecific information seeking undirected or conditional searching problem-driven information seeking informal or formal Information-Gathering Process by Selected Groups

37 INFORMATION WORKERS / MANAGERS environmental scanning viewing undirected (casual exposure to information) conditional (purposeful but nonspecific such as browsing a newspaper) searching informal (unstructured, cursory check of current facts or data) formal (structured and in- depth, directed to a specific problem) Information-Gathering Process by Selected Groups

38 INFORMATION WORKERS / MANAGERS complex tasks require more varied sources than routine tasks, diversified approaches to information seeking, interpretation and construction of information, and result in increased uncertainty and anxiety

39 Information-Gathering Process by Selected Groups Donald Case: Conceptual Organization and Retrieval of Text by Historians: The Role of Memory and Metaphor. JASIS 42(9) 1991 HISTORIANS Case designs a study of information systems of historians (teachers and researchers and observes the patterns of behavior with regard to: spatial organization, organization by form, organization by topic)

40 Information-Gathering Process by Selected Groups HISTORIANS method of research: participant-observation, interviews personal ISAR systems of historians (spatial logic of PIS focuses on offices, how they organize piles of documents, what media they use, how they process information from the information sources and recall / retrieve documents at a later time)

41 Information-Gathering Process by Selected Groups HISTORIANS spatial organization organization by form aesthetics as sorting criterion, form over content (oversized, paperbound, old/new) keep like things together and close at hand (reminding function)

42 Information-Gathering Process by Selected Groups HISTORIANS organization by topic organization by treatment, purpose, quality purpose as sorting criterion (good and bad books, textbooks and research books, etc.) keep like things together and close at hand (reminding function)

43 Information-Gathering Process by Selected Groups HISTORIANS number of filing cabinet drawers and other storage devices, linear footage of books, journals and notebooks in offices and how arranged number of stacks of material lying around the office (19-49) -- physical scheme of organization, not categorical! sometimes used spatial orientation and other times space in combination with specific labels spatial organization

44 Information-Gathering Process by Selected Groups HISTORIANS subjects’ decisions on how to organize documents is individual not based on document characteristics (Kwasnik: order of importance determined by context, form, use, topic, location, circumstance) levels of information storage determine organization of documents: action, personal work files, archive examples of movement in these 3 levels: once a semester we clean up our working spaces to be able to reuse information not needed now)

45 Information-Gathering Process by Selected Groups HISTORIANS metaphorical use of space: proximity to the chair denotes urgency spatial clues -- interaction needed to remember and recall (appropriate only for immediate action, reminder of what to do) weakens as interaction with documents decreases

46 Information-Gathering Process by Selected Groups HISTORIANS problems with retrieval in systems organized around space (losing files, misplacing information, need to rely on memory for recall) memorizing possible through visualization of details (facts in physical structures) spatial logic of elements is less vital while knowledge of category structures becomes more important as information is moved from action, personal working files, to archived files

47 Information-Gathering Process by Selected Groups HISTORIANS crowding does not hinder but improve cognitive recall (although historians apologized for their offices being untidy); arrangement otherwise would destroy links and patterns and associations that are mnemonic card is a powerful metaphor for historians who are trained to collect information in card-like chunks (conceptual nature of the card as unit of information, a single, multiple instance of ideas, evidence, question, quotation, document)

48 Information-Gathering Process by Selected Groups HISTORIANS organization by topic sporadic efforts to build and maintain indexing / elaborate filing systems which are abandoned labeling is difficult because tied to physical object (objects fall into more categories) -- need to produce a card system that would be access to the location of items which are in different formats or make duplicates (impractical to index that way)

49 Information-Gathering Process by Selected Groups HISTORIANS organization by topic reasons for abandoning filing systems is that indexing in paper-and-pencil environment entails high costs for the benefits received in later retrieval indexing card system used by historians: systems to aid writing (detailed chronologies in case of historians), keeping track of literature

50 Information-Gathering Process by Selected Groups HISTORIANS implications of findings How to implement spatial dimensions in computer interface and to enrich temporal and physical retrieval cues for electronic files? Evidence of inadequacy of existing display and manipulation devices for historians.

51 Information-Gathering Process by Selected Groups HISTORIANS implications of findings for system development 1. Thoughts / ideas are knowledge spaces in search of a physical location for storage 2. Historians use chronological and geographical facets for information rather than standard vocabulary for topics (display devices needed: maps, chronological) 3. Tactile associations with the material (sensory gloves for document manipulation)

52 Information-Gathering Process by Selected Groups Susie Cobbledick: The Information-Seeking Behavior of Artists: Exploratory Interviews. Library Quarterly 66(4) 1994 ARTISTS method of research: in-depth interviews with 4 artists (sculptor, painter, fiber artists, metalsmith) neglected group of information professionals

53 Information-Gathering Process by Selected Groups ARTISTS inspirational information (sources of ideas, moods, emotions, general or suggestive visual information) technical information information about current developments in the visual arts shows, commissions, and sales technology, books sources

54 Information-Gathering Process by Selected Groups ARTISTS artists make substantial use of libraries and print materials much of this material is not art related they typically find this material by browsing within specific subject areas they make substantial use of interpersonal sources to obtain technical information and information about developments in the local art scene sources

55 Information-Gathering Process by Selected Groups ARTISTS survey instrument designed to aid data collection from this group age, educational background, medium of creative expression, geographic location sources of visual and inspirational information sources of technical information sources of information about current developments in the visual arts shows, commissions, and sales library use, technology use, book use reliance on gatekeepers and invisible colleges information needs profile

56 Information-Gathering Process by Selected Groups ARTISTS libraries for artists need to be heavy on print materials whose verbal and visual content covers a wide array of topics without an undue emphasis on art portability of materials is important (need to take visual information to the studio) high-quality photocopying should be available on the premises, and material should be circulating; access to hardware and software for multiplication Implications for building libraries for artists

57 Information-Gathering Process by Selected Groups ARTISTS size of the collection: small but concentrated sources: technical manuals, visual arts journals, art monographs MARC records should be enhanced to include information about illustrations development of visual databanks Implications for building libraries for artists

58 Information-Gathering Process by Selected Groups P. Sandstrom: An Optimal Foraging Approach to Information Seeking and Use. Library Quarterly 64(4) 1994 SCIENTISTS foraging theory

59 Information-Gathering Process by Selected Groups John Agada: Inner-City Gatekeepers: An Exploratory Survey of Their Information Use Environments. JASIS 1999 SOCIAL GROUP: AFR0-AMERICANS disadvantaged groups and communities

60 Information-Gathering Process by Selected Groups SOCIAL GROUPS cf. Metoyer-Duran: developed set of profiles based on study of ethno-linguistic gatekeepers in the American- Indian, Chinese, Japanese, Korean and Latino communities in California; Agada: African-American community gatekeepers community information need profile

61 Information-Gathering Process by Selected Groups B. Hjoerland and H. Albrechtsen: Toward a New Horizon in Information Science: Domain-Analysis. JASIS 46(6) 1995 DISCOURSE COMMUNITIES domain analysis -- social aspects of information-seeking process
