Foil 7 Overview of DR-LINK High Level Natural Language Database Interface

From Second Part of RDBMS Discussion ARL Database Tutorial -- February 98. by Gang Cheng Marek Podgorny Chao-Wei Ou


This research activity of Professor E. Liddy of Information Studies School at Syracuse University is being commercialized by InfoMall member -- the start-up company Textwise.
The Surface Realizations i.e. particular strings of words in documents or database quert, do not reflect the breadth, richness or precision of meaning intended by either
  • Author of Document
  • Presenter of Query
Simple word level representation cannot produce the recall and prescision possible when the full conceptual intent of queries and documents is the basis of retrieval
  • Thus DR-LINK matches on the concepts of interest to the user and not just the words of interest
DR-LINK achieves this deeper conceptual representation of texts by utilizing all the levels of language at which meaning is conveyed:
  • Lexical, Syntactic, Semantic and Discourse levels of language
  • DR-LINK combines these multiple levels of conceptual representation of text
