Presentation and demonstrations by Jerzy Lewak, cofounder & CTO of Speedtrack Inc, CEO and President of
Nisus Software Inc.

Two applications of this Dynamic Interactive Semantic Search and information discovery tool will be demonstrated.

The discovery domains will be:
- An unstructured database of newspaper articles
- A structured database of crime incidents

This approach and display of Guided Information access (GIA), is made possible only by leveraging the novel approach underlying the TIE (Technology for Information Engineering) system.

Information is exhibited through associations of, or links between the data elements. Utilizing this unique approach, TIE is thus able to focus on a dynamic display of associations whilst guiding a user through information discovery.

Faceted Navigation uses the principal starting idea of the TIE system. Faceted Navigation is currently actively discussed and in its elementary incarnation used on hundreds of web sites. Its severe limitations prevent its general application to all kinds and sizes of data.

The technology behind the TIE system enables it to overcome all the major limitations of Faceted Navigation, leveraging a mechanism which focuses on information storage, its display and its retrieval.

GIA is applicable to any kind of data, local or distributed; structured, unstructured or mixed and has been demonstrated with databases of documents, publications, emails, medical data, crime data, insurance data and weblogs.
