Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0042] Such as figure 1 As shown, the present invention utilizes network news to perform character recognition and image analysis on the acquired network news, establishes a news ID for the news and finally puts it into a news database to streamline network news and classify and filter network news. Among them, text recognition relies on keyword extraction based on lexical chains, and image classification is based on deep learning algorithms to classify images.

[0043] The method relying on the extraction of keywords based on lexical chains includes the following steps:

[0044] (1) Set the number of extracted keywords k, word similarity threshold δ, feature frequency threshold ε

[0045] (2) Preprocessing the document set, including word segmentation, part-of-speech t...

Abstract

The invention provides a network news outline extraction method. The method comprises the following steps: firstly obtaining network news, extracting a keyword from characters in the network news on the basis of a Chinese vocabulary chain, and carrying out picture classification on the basis of a deep learning method; establishing a news ID and storing the news; and comparing the news. According to the network news outline extraction method, a key abstract is extracted according to Chinese information in the network news and the news pictures are classified to form the news ID, so that one piece of news corresponds to one news ID, the storage requirement of the system is greatly reduced and the storage efficiency is improved. Through the unceasing real-time updating of a mentioned news library and provided functions such as rapid query and addition, the news retrieval efficiency is improved, the workload of checking and evaluating the news by the workers is greatly reduced, and effective news screening ancillary work is provided.
