METHOD AND DEVICE FOR DETERMINING RELEVANCE BETWEEN NEWS AND FOR CALCULATING THE RELEVANCE BETWEEN NEWS

摘要

Provided in the present invention are a method and device for determining the relevance between pieces of news and for calculating the relevance between pieces of news. The method for determining the relevance between pieces of news comprises: comparing a piece of first news with a piece of benchmark news to produce the distance between the first news and the benchmark news; comparing a piece of second news with the benchmark news to produce the distance between the second news and the benchmark news; calculating the distance difference between the distance between the first news and the benchmark news and the distance between the first news and the benchmark news, and determining the relevance between the first news and the second news on the basis of the distance difference. The method for calculating the relevance between pieces of news comprises: determining a primary correlation between the first news and the second news; determining a primary correlation between the second news and a piece of third news; and establishing a secondary correlation between the first news and the third news on the basis of the primary correlation between the first news and the second news and of the primary correlation between the second news and the third news.
