Knowledge identification
• goal

– prepare them for specification
• input
– knowledge-intensive task selected
– main knowledge items identified.
– application task classified
• assessment, configuration, combination of task types
• activities
– explore and structure the information sources
– study the nature of the task in more detail

The basic model
Core concepts based on the
back-of-book index
Extended and generalized for
use with digital information
Consider a two-layer model
consisting of
– a set of information resources (below)
– a “knowledge map” (above)
This is like the division of a
book into content and index
knowledge layer
information layer
(index)
(content)
Callas, Maria …………………… 42
Cavalleria Rusticana … 71, 203-204
Mascagni, Pietro
Cavalleria Rusticana . 71, 203-204
Pavarotti, Luciano ……………… 45
Puccini, Giacomo ………. 23, 26-31
Tosca ………………. 65, 201-202
Rustic Chivalry, see Cavalleria
Rusticana
singers ………………………. 39-52
baritone ………………………. 46
bass ……………………….. 46-47
soprano ……………… 41-42, 337

(2) The knowledge layer
The upper layer consists of topics and associations
– Topics represent the subjects that the information is about
Like the list of topics that forms a back-of-book index
– Associations represent relationships between those subjects
Like “see also” relationships in a back-of-book index

Enterprise information integration
Topic Maps are designed for ease of merging
– Generate topic maps from structured data
(or create topic map
views of that data)
– Merge topic maps to provide
a unified view of the whole
Easy to filter
– Create personalized views
of this unified model
Advantages:
– Consolidated access to
all related information
– No need to migrate
existing content
– Standards-based

Visualizing topic maps
The network or
graph structure of a
topic map can be
visualized for
humans
This provides
another “view” on
information that can
lead to new insights
(Demo of visualization
using Vizigator)
