Textual database system using skeletonization and phonetic replacement to retrieve words matching or similar to query words
Patent 4674066 Issued on June 16, 1987. Estimated Expiration Date: March 3, 2006. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
An electronic database search system can identify database records having textual expressions that match, or are similar to, an operator-designated search expression. The system features a mechanism for transforming linguistic expressions, e.g., words, into linguistically salient word skeletons. Skeletal modification and suffix stripping features are employed to enhance expression-matching qualities of the word skeletons and to reduce data storage requirements.
