What is “information behavior”?
What is a model and why use it?
Types of models
Individual models
Model-building exercise
Discussion
LIS-505
2
“a process in which humans purposefully engage in order to change their state of knowledge”
(Marchionini,
1995, p. 5)
“the study of how people need, seek, give, and use information in different contexts, including the workplace and everyday living”
(Pettigrew, Fidel & Bruce,
2001, p. 44)
“a process that includes multiple stages of question asking and refining, information gathering and evaluating…synthesis and use of information”
(Wallace,
Kupperman, Krajcik, & Soloway, 2000).
Study of the user of information rather than the container
LIS-505
3
Paradigm shift (1980s)
To identify different user groups and their information needs
How people think and behave in response to information needs.
Patterns of behaviours
To identify best practices
To inform information system design
LIS-505
4
Diagrammatic, simplified versions of reality
More concrete – “real world”
To study various aspects of phenomena:
Characteristics
Relationships
Specific to general
Different intellectual domains:
Cognitive
Affective
Context independent
Predictive value
LIS-505
5
Of great value in the development of theory
description prediction explanation
Models = Tentative, proposed set of relationships
Focus on more specific or limited problems
Concrete, diagrammatic
Frameworks
Generalizable – specific situation to general contexts
LIS-505
6
Types of Models
Different types of models:
Instructional
Grounded
Narrative
Synthesized
Based on Information Need
LIS-505
7
Dervin’s Sense-Making Model
(1980’s to Present)
Information and human communication interlinked and inseparable
Identification and explanation of universals within individual experiences
Bridging gaps
Multiple interpretations – not the “right” answer
Personal meaning – integration of results into one’s own experience
No value judgments on what constitutes “helpful” information
LIS-505
8
The Sense-Making Triangle
SITUATION
GAP
In Glazier and Powell (1992) p. 69.

9
Taylor’s Levels of Information Need (1968)
1.
2.
3.
4.
Visceral : unconscious – difficult to articulate
Conscious : awareness but ill-defined
Formalized : concrete – definitive and rational question
Compromised : need is redefined and specific to information system
Independent of the type of information need
Implications for intermediary’s approach
10
LIS-505
Belkin’s ASK – 1980
(Anomalous State of Knowledge)
Set of guidelines
Gap in one’s knowledge that needs bridging
Information need to be defined in terms of user not system
Levels of information need continuum
Most Vague Most Specific
• Different retrieval tasks for different ASKs
LIS-505
11
Wilson’s Macro-Model (1981 and 1996)
Broader perspective than just electronic systems
“Goal-seeking behaviour”
Problem identification Problem definition
Problem resolution Solution Statement
Stress/coping theory – satisfaction of information need
“Intervening variables” = barriers (but not always)
Feedback loop
Risk/Reward Theory
Social Learning Theory
Self-Efficacy
Nested together
LIS-505
12
LIS-505
13
Kuhlthau’s Information Search Process
Seeking meaning – constructivist
Concept of uncertainty – anxiety, motivation
LIS-505
14
LIS-505
15
Starting – identification of key areas of interest
Chaining – identifying references
Browsing – familiarizing oneself with sources within subject area
Differentiating – value judgments based on prior knowledge
Monitoring – regular examination of identified key sources
Extracting – perusal of a particular source to identify and select relevant material.

LIS-505
Information Search Strategies
Belkin, Marchetti & Cool (1993)
Dimensions of Information-Seeking
Strategies
method of interaction (scanning-searching) goal of interaction (learning-selecting) mode of retrieval (recognition-specification) resource considered (information items-meta information)
Any ISS could have 16 possible combinations of these four dimensions
LIS-505
17
LIS-505
18
Addresses 4 areas:
1.
2.
The nature of the query,
The nature of the overall search process,
3.
4.
The range of search techniques used
The information ‘domain’ or territory where the search is conducted
“Bit-at-a-time retrieval” – selected tidbits of information
Evolving search query
LIS-505
19
LIS-505
20
Shenton & Dixon’s (2003) Macrocosmic Model
1.
Identification of overall direction
Determines nature of information need
2.
Identification of source
Identification and isolation of sources
3.
Identification of component
Interaction with the information source
Identification and examination of components within sources
LIS-505
21
Shenton & Dixon’s (2003) Macrocosmic Model
1.
Accessing of information
May have been done in Stage 3
Possible redirecting of search
2.
Outcomes and future action
Decision about usefulness of materials
Decision as to whether to stop or continue search process
22
LIS-505
Elements similar to Wilson’s model namely
“active search” mode
Makes a number of elements explicit
Functions of the information user, document author, intermediary
Brings IR system into the picture
Cognitive transformations from life-world to information system
23
LIS-505
24
Methodological Issues: A Paradigm War?
Quantitative vs. Qualitative methodology
Mixed methods
Random vs. purposeful sample
Experimental vs. Operational setting
Information System vs. User
Generalizability vs. Transferability
Methodology must match the research question!
25
LIS-505
Nesset’s Preparing, Searching & Using (PSU) Model
LIS-505 26
Emerging patterns and themes
Best practices
Information system design
Models inform theory
Description Prediction Explanation
LIS-505
27
Elements to include:
Information need
Question/query development
Generalized search/broad topic refinement of topic/query
User demographics
Task definition (what is the information for?)
How will the information be used?
Organization of retrieved information
Evaluation of information for relevance
Feedback feature
Barriers/facilitators to information search process
Intervening variables (those things out of searcher’s control)
Affective, physical, and cognitive behaviors
Evaluation--feedback
LIS-505
28
Visuals
Relationship arrows —steps involved in process
Beginning and end (entrance/exit points)
Stages (shows progress/evolution)
Text and/or images
Cyclical
Spectrum of possible affective behaviors
Categorizing of similar elements
Legend/key – use of different colors/fonts
Representation of concepts using different shapes, colors, symbols, arrows, etc. – building a conceptual framework
Title (don’t make your readers guess)
Borders/parameters
