Abstract

The embodiment of the invention provides a text similarity processing method which comprises the following steps: acquiring Internet information and generating a metadata characteristic vector; constructing a concept tree according to the generated metadata characteristic vector, and generating subtrees based on the constructed concept tree; and calculating the similarity among texts in the acquired Internet information via the subtrees. The text similarity processing method has the advantages that manual operation is avoided, so as to reduce labor cost; and the accuracy is high.

Description

technical field [0001] The invention relates to an information processing method, in particular to a text similarity processing method. Background technique [0002] With the rapid growth of Internet information, how to obtain the information needed by users from massive information is an important research work at present. Text similarity calculation has been widely used in related research on text mining, artificial intelligence, information retrieval, knowledge management, etc. at home and abroad. At present, similarity calculation methods are mainly divided into traditional methods based on large-scale text set statistics and methods based on semantic calculation. [0003] Methods based on large-scale text set statistics usually use vector space model (VectorSpaceModel, VSM) and latent semantic indexing model (LatentSemanticIndexing, LSI) and other methods. These methods are based on keywords for similarity calculation, without considering the semantic information of f...
