Method for determining synthetic term senses using reference text

摘要

A method for determining term senses by identifying terms having multiple “senses” or meanings. For a given source term and trigger term, a list of important terms having high relevance to a combination of the source term and trigger term is created. The list of important terms is determined to be a “sense” for the source term in accordance with the present invention. A sense is assigned to a given term of a given document by determining similarity of the document to one or more senses and assigning a sense as a function of the degree of similarity. A sense-indicative index is created to treat multiple occurrences of a term distinctly, as a function of each respective assigned sense. Accordingly, the index may be used for sense-relevant information retrieval when a sense of a query term is discernible or specified.
