  • Method and system for information extraction
    Patent number: 7657425
    Abstract: A method, a system and a computer program for extracting information from a natural language text corpus based on a natural language query are disclosed. The natural language text corpus is indexed and stored. A natural language query is analyzed with respect to phrases, phrase types, syntactic roles, word tokens of phrases, and lexical meaning of word tokens. One or more surface variants are created for at least one phrase of the natural language query. The one or more surface variants each have the same phrase type as the at least one phrase of the natural language query, and each comprise a word token which is a lexical head and has the same lexical meaning as a word token which is a lexical head of the at least one phrase of the natural language query. The one or more surface variants and the at least one phrase of the natural language query are compared with the indexed and stored natural language text corpus.

  • Method and system for information extraction
    Patent number: 7194406
    Abstract: A method and a system for extracting information from a natural language text corpus based on a natural language query are disclosed. In the method the natural language text corpus is analyzed with respect to surface structure of word tokens and surface syntactic roles of constituents, and the analyzed natural language text corpus is then indexed and stored. Furthermore a natural language query is analyzed with respect to surface structure of word tokens and surface syntactic roles of constituents. From the analyzed natural language query one or more surface variants are then created, where these surface variants are equivalent to the natural language query with respect to lexical meaning of word tokens and surface syntactic roles of constituents.
