Problems solved by technology

However, the vector space model has the defect that the data space expression is sparse and the semantic information between words is ignored, which leads to its weak ability to express short text

Abstract

The present invention relates to a short text representation method based on word2vec, comprising the following steps: S1: input a training text set through text preprocessing, set word2vec method parameters, and train to obtain a word vector set corresponding to the training text set; S2: for each article Each word in the document is calculated by the cosine distance between the word vectors to obtain a series of similar words of the word in the entire training text set; S3: calculate the cosine distance between the similar words in each document and the document; S4: according to the cosine distance Sort from large to small, and finally select the first n similar words and the corresponding cosine distance to form n similar words and cosine measures of the document; S5: Calculate the weight of the word in the document and the selected n similar words in the document, Form a new text representation and output a word2vec-based vector space representation for each document.

Description

technical field [0001] The present invention relates to the field of computer science and technology, and more specifically, relates to a short text representation method based on word2vec. Background technique [0002] In text mining processing, machine interpretation of sample information needs to go through the text representation process to convert samples into numerical values. With the continuous expansion of the scope of natural language processing and the development of computer technology, how to use numerical values ​​to better represent the semantic information represented by text has always been one of the most important research points in the field of text processing, because it directly affects text mining. Effect. For short text mining, effective text feature representation methods are even more difficult to research, especially short texts generated by social platforms, which not only have traditional features such as sparse features, incomplete semantics, p...
