Abstract
The method of estimating the relevance of a document with respect to a concept comprises calculating (32) a relevance function of the concept with respect to said document on the basis of a known predetermined semantic neighborhood of the concept. It further comprises calculating an ambiguity function of said concept in said document, which ambiguity function is different from the relevance function, said calculation being an estimation based on the presence in the document of different meanings of the concept. The method follows on from a preliminary step of detecting ambiguous concepts in a database.
Claims11
A method of estimating a relevance of a document with respect to a concept comprising:
- calculating a relevance function of the concept with respect to said document based upon a known predetermined set of concepts in a knowledge base that are related to that concept by different semantic links,
- said set of concepts being called a semantic neighborhood of the concept,
- determining whether said document is relevant with respect to the concept and when so determined, calculating an ambiguity function of said concept in said document, which ambiguity function is different from the relevance function, estimation related to by estimating the presence of different meanings of the concept in the document, and marking the document considered to be relevant with a result of the calculation of the ambiguity function.
A method of estimating a relevance of a document with respect to a concept comprising:
- calculating a relevance function of the concept with respect to said document based upon a known predetermined set of concepts in a knowledge base that are related to that concept by different semantic links,
- said set of concepts being called a semantic neighborhood of the concept,
- and, if the document is considered to be relevant with respect to the concept:
- calculating an ambiguity function of said concept in said document,
- which ambiguity function is different from the relevance function,
- estimation related to by estimating the presence of different meanings of the concept in the document, and
- marking the document considered to be relevant with a result of the calculation of the ambiguity function
- and, if the document is not considered to be relevant with respect to the concept:
- marking the document as not being relevant.
