AUTOMATED COMPUTATION OF SEMANTIC SIMILARITY OF PAIRS OF NAMED ENTITY PHRASES USING ELECTRONIC DOCUMENT CORPORA AS BACKGROUND KNOWLEDGE
First Claim
1. A method for automatically providing an overall semantic similarity score value among named entities, comprising:
- calculating for each pair in at least a selection of pairs of the named entities, a pair similarity score value according to a classifier using at least one electronic information source;
calculating for each of the pairs in the selection of the pairs of the named entities a further pair similarity score value according to a further classifier using the at least one electronic information source; and
calculating for each of the pairs in the selection of the pairs of the named entities an overall semantic similarity score value as a first function of the pair similarity score value and the further pair similarity score value corresponding thereto.

Abstract
An overall semantic similarity score value between pairs of named entities in a text corpus is obtained by calculating for at least one pair of named entities a plurality of corresponding pair similarity score values according to a first and at least a second classifier using electronic information sources. Each pair similarity score value of the pair of named entities per classifier is normalized by calculating a rank list per classifier, for example, for each named entity. The rank list holds each pair of named entities of the text corpus, wherein a rank of each pair of named entities within the rank list reflects the respective pair similarity score value. Further an arithmetic mean of the normalized pair similarity score value of each pair of named entities is calculated to provide the overall semantic similarity score value.
