INFO 414 Information Behavior
Analysis, synthesis and evaluation
Slide 2
As intellectual processes (Bloom)
Analysis (identifying elements and organizing principles)
Ability to break down into parts
Ability to see relationships
Synthesis (putting bits back together)
Ability to put together to form a new whole
Ability to combine ideas to develop a new structure
Evaluation
Ability to judge value for purpose and support with relevant criteria
Slide 3
Analysis of information
process of determining and isolating the most salient information conveyed by an information source and separating this information into its constituent elements on the basis of predetermined evaluation and other criteria.
Slide 4
Synthesis of information
Process of condensation and distillation of analyzed information from one or more sources and presentation of information in a new arrangement or structure with an interpretative or evaluative point of view
Slide 5
Preliminary to analysis and synthesis...
Study of subject area (subject expertise) where information will be analyzed and synthesized
Study of users for whom analysis and synthesis will be done
Objectives, resources and constraints. The context in which analysis and synthesis is performed
Determining the evaluative criteria for analysis and synthesis
Slide 6
Steps in analysis of information...
Familiarization
Preliminary sorting on the basis of subject knowledge and evaluative criteria (E1)
Selection and extraction of relevant or salient features. Filtering. Reduction of materials to be handled
Verification of information (E2)
Sorting of information
Slide 7
Steps in synthesis of information...
Arrangement of extracted information
Comparative evaluation of the information in different classes or categories (E3)
Decisions related to presentation of conflicting or contradictory information in the synthesis
Compression of information into a form and structure suited to intended users
Evaluation of the final product based on criteria related to users (E4)
Slide 8
Evaluation stages...
Analysis and synthesis of information incorporates 4 stages of information evaluation
evaluation of information sources
verification of information
Comparative evaluation of the information in different classes or categories following analysis
Evaluation of the synthesized product
