Abstract

The invention provides a method for extracting keywords. The method includes the steps that word segmentation operation is performed on all analysis sentences of an extracted text so as to obtain wordunits of the analysis sentences; word features of the word units, sentence features of the word units in the corresponding analysis sentences and text features of the word units in the extracted textare obtained; based on a robot learning model established through a robot learning algorithm, by the utilization of the word features of the word units in all the analysis sentences, the sentence features and the text features, keyword extraction operation is performed on each analysis sentence. The invention further provides a device for extracting the keywords. According to the method and device for extracting the keywords, the word features of the word units, the sentence features and the text features are used for establishing the robot learning model, then the keyword extraction operation is performed on each analysis sentence, and then the accuracy of keyword extraction is improved.

Description

technical field [0001] The invention relates to the field of text processing, in particular to a keyword extraction method and a keyword extraction device. Background technique [0002] With the development of the information age, the ways of expressing information are becoming more and more diverse, and the way of expressing information by using text is irreplaceable. With the development of the network, the amount of online text information is growing explosively, and it is increasingly difficult to manually obtain the required text information. Therefore, how to efficiently obtain information has become a very important issue. [0003] In order to effectively process massive text data, researchers have done a lot of research in the directions of text classification, text clustering, automatic summarization and information retrieval, and these studies all involve a key and basic problem, that is, how to obtain keywords in the text. Therefore, in tasks such as natural lan...
