Abstract

The present application discloses a hot word processing method and apparatus. The method comprises: carrying out word segmentation on the target corpus obtained from a text of target tags so as to obtain a plurality of word segmentation; clustering the plurality of word segmentation to obtain a plurality of clustering result sets; calculating an entropy value of each of the plurality of word segmentation in the clustering sets, wherein the entropy value is used to characterize the feature level of the word segmentation, and the clustering set is a set of a plurality of clustering result sets; selecting word segmentation whose entropy value is larger than the preset threshold in the plurality of word segmentation, so as to obtain target word segmentation; and deleting the target word segmentation from the statistical hot words associated with the target tags. According to the method and apparatus disclosed by the present application, the technical problem of low efficiency in the prior art due to that the hot words with low feature level are deleted by using an manual manner is solved.

Description

technical field [0001] The present application relates to the field of computers, in particular, to a method and device for processing hot words. Background technique [0002] When analyzing some topics, it is usually necessary to count the hot words in the topic, and the hot words refer to N words that appear in a certain percentage of texts related to the topic. In the process of counting hot words, it is often encountered that hot words in different topics in the same field have a great similarity, and some hot words that are common in this field will appear in almost all topics in this field Happening. For example, when analyzing the topic of a legal case, no matter the topic is a divorce case, a traffic accident case or a civil dispute case, words such as "plaintiff" and "defendant" will appear in the topics of all legal cases, so the above Hot words have a low degree of feature and are non-feature words. Therefore, it is not helpful to express the characteristics of...
