SIGMA QUERY LANGUAGE

UNIFIED QUERY LANGUAGE: We want to query data sources and databases seamlessly using an SQL-like query language.
Hypermapped Virtual World Metaphor: To support visual querying, we can integrate the user's view of the information spaces with the underlying semantic model.

Criteria for Evaluation:
For content-based access of multimedia, can relevant associations be easily discovered? Can new associations be easily created, encoded and maintained?

Multilingual Interfaces:
Although visual interfaces are supposedly "universal", the meanings of visual symbols (icons) do shift across cultural boundaries. A solution is to provide multilingual interfaces so that the user can shift to the user's native language in an interactive session.
