What is Information Behavior?

“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

Why Study Information Behavior?

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

What is a model and why use it?

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

Why Information Behavioral Models?

 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.

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

13

Kuhlthau’s Information Search Process

Seeking meaning – constructivist

Concept of uncertainty – anxiety, motivation

LIS-505

14

Kuhlthau’s Information Search Process

LIS-505

15

Ellis’ Behavioural Framework (1989)

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.

16

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

18

Bates’ (1989) Berry-Picking Model

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

Bates’ Berry-Picking Model

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

Ingwersen’s Cognitive Model

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

Ingwersen’s Cognitive Model (1996)

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

So What?

 Emerging patterns and themes

Best practices

Information system design

Models inform theory

Description  Prediction  Explanation

LIS-505

27

What would your model look like?

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

What would your model look like?

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
