Problems solved by technology

However, if two words are far apart in the text but semantically closely related, existing methods cannot discover this connection
In addition, the existing methods only use the shortest path to measure the importance of each node when calculating the importance of each node, and the features are relatively single
The words with high importance obtained by using existing methods may not necessarily represent the semantic information of the original text
When calculating the importance of each node at the same time, it is necessary to calculate all the shortest paths in the network every time, which is inefficient

Embodiment Construction

[0054] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0055] Such as figure 1 Shown is a flowchart of a method for discovering hotspot information in an embodiment of the present invention, including the following steps:

[0056] Step 101, acquire text to be processed.

[0057] Step 102, perform word segmentation and part-of-speech tagging on the text to be processed.

[0058] For example, a conditional random field-based method may be used to perform word segmentation and part-of-speech tagging on the text to be processed. Of course, other methods can also be used for word segmentation and part-of-speech tagging. For example, the longest word matching can be used for word segmentation, and methods based on HMM (Hidden Markov Model, Hidden Markov Model) can be us...

Abstract

The invention discloses a hotspot information finding method and system. The method includes the steps of obtaining a to-be-processed text, conducting word dividing and part-of-speech tagging on the to-be-processed text, conducting parsing on the text subjected to word dividing to obtain a dependence syntactic tree of each sentence in the to-be-processed text, removing stop words in the dependence syntactic tree of each sentence in the to-be-processed text to obtain to-be-analyzed dependence syntactic tree, establishing a small world network through the to-be-analyzed dependence syntactic tree, conducting hotspot analysis according to the to-be-analyzed dependence syntactic tree and the small world network, and obtaining hotspot information in the to-be-processed text according to the hotspot analysis result. By means of the method and system, the hotspot information in the to-be-processed text can be efficiently and accurately found.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a method and system for discovering hotspot information. Background technique [0002] With the rapid development of the Internet and the continuous improvement of storage technology, more and more text information is flooding around us. However, there is a lot of redundancy in this information, and reading step by step will obviously waste a lot of time and energy for users. The hotspot analysis method can quickly extract key vocabulary or sentence information from a large amount of text information, that is, hotspot information, so that users can quickly and easily understand the important information contained in the text, which has become a research hotspot for researchers. Therefore, how to efficiently and accurately conduct hotspot analysis on the text and find the corresponding hotspot information in the text to be processed has become the primary task of hotspot anal...
