Text Mapping for Technology Watch A research application Z. Jacobson, CA

First Problem Discover the conceptual relations among elements of text in a massive corpus. Documents or Web pages

Problem Spot conceptual or meaningful relations among elements of text in a massive corpus. Documents [or Web pages] Clusters of similar items scant conceptual “regions

An answer, possibly Use large, parallel input mode --vision. i.e., Convert problem to navigation among elements and features in space e.g., driving in traffic; swimming underwater

Successive realizations VITA--Visual Interface for Text Analysis [For VIncent TAylor, DND, CA] A “bolt-on” visual rendering accepts search engine results to user’s query on a text corpus.

VITA Virtual reality 3D interactive “tunable” to user: Best parameters for task, --for this user.

Previous versions

Clustering algorithms

A “bolt-in” tool Accepts several standard search engines User interacts with Display Engines Text corpus

Ante-penultimate version

MTCMTC Aalborg Network of Experts, October 2001

Current Version C++ Proper Object-orientation Hardened against many more “hits”

MTCMTC Aalborg Network of Experts, October 2001 Six Questions the evaluator should ask 1. What is the user trying to achieve at this point? 2. Can the user perceive whether there is progress toward achieving the goal? 3. Is the user able to influence the element? 4. What external influences might affect the user's ability to perceive the element's behaviour? 5. What external influences might affect the user's ability to affect the element's behaviour? 6. Is there provision for alerting the user to any other element(s) that might be important at the moment?

Use—Technology watch DTAP Defence Taxonomy Canadian Projects. Situation amenable to query—term—hit paradigm.  Shows relations among defence technologies and CA projects.

Application to a website Terms applied to Strategis for tech watch TTCP Allies.

A research project —will the mappings prove useful? For evaluation Hope to find other test situations !

Future developments Does it help the user? How well does it work for the user? Why does it work?
