Problems solved by technology

[0003] In the existing technologies, the LDA+ (Latent Dirichlet Allocation, document topic generation) model or the KeyGraph algorithm is used to realize the document clustering of news documents, but the above-mentioned methods are easy to cluster large event news document clusters, which leads to the accuracy of fine-grained news event detection. and lower recall

Abstract

The invention provides A method for document cluster which includes construct a word co-occurrence network according to a plurality of documents to be clustered; Calculating the link similarity between any two links connected to the same node in the word co-occurrence network; Extracting a plurality of keyword communities from the word co-occurrence network according to the link similarity; According to the document representation vector of each document to be clustered and the community representation vector of each keyword community, assigning Each document to be clustered to a correspondingkeyword community respectively, and genertaing an initial document cluster corresponding to each keyword community according to the allocation result, wherein all documents to be clustered located inthe same keyword community constitute an initial document cluster. The present disclosure also provides a document clustering platform, a server, and a computer readable medium.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a document clustering method and platform, a server, and a computer-readable medium. Background technique [0002] An event refers to something that happened in a certain place on a certain day. Many events occur and are reported every day in the world, and a large amount of Internet information news is generated from this. Clustering the news documents of massive internet news every day to automatically detect fine-grained news events in real time (such as daily-level news events), which can help and support public opinion analysis, realize news recommendation, or be used in articles The role of automatic writing. [0003] In the existing technologies, the LDA+ (Latent Dirichlet Allocation, document topic generation) model or the KeyGraph algorithm is used to realize the document clustering of news documents, but the above-mentioned methods are easy to cluster large...
