Successive principal axes filter method of multi-document automatic summarization

Abstract

This invention relates to one multi-file automatic abstract order main axis filter method in text information technique, which is based on OR rotation axis method comprises the steps of sentences similarity computation and analyzing main axis and abstracting sentence redundant part.

Description

technical field [0001] The invention belongs to the technical field of text information, and in particular relates to a multi-document automatic summarization method. Background technique [0002] With the rapid development of communication, people are increasingly enjoying the convenience brought by information, especially text information, including emails, web pages, short messages and so on. A problem that comes with it is that the large amount of information often makes it difficult to grasp the key points. How to use computers to help people analyze these information and pick out important information has become a very important issue. Automatic summarization is produced to meet such needs. It is divided into single-document summarization and multi-document summarization. Due to too much information in reality, multi-document summarization is more widely used. It generates an abstract for multiple documents and submits it to users. The current summarization technolo...

Problems solved by technology

The advantage of this method is that the accuracy is relatively high, but the disadvantage is that it is not widely used. Generally, it only summarizes documents in a specific field, and the cost of manually giving a summary is also very expensive.

[0004] 2. Unsupervised summarization algorithm

The advantage of the unsupervised summarization algorithm is that it is fast, does not require a manually labeled training set, and the application is not limited by the field; the disadvantage is that the accuracy is not very high
