Project Summary

(i) Combining Technologies: integrating technologies for information retrieval, database management, and hypertext navigation, to achieve a "universal" information model; 

(ii) Personalization: developing tools for personalizing information management; 

(iii) Semantics: Using natural-language processing and structural techniques for analyzing the semantics of Web pages; and 

(iv) Data Mining: designing new algorithms for mining information in order to synthesize new knowledge.
