Abstract

The invention provides a method for calculating short text semantic similarity. The calculating method comprises the steps of segmenting to-be-calculated short text; extending the segmented words through a continuous bag of words; eliminating ambiguities of the extended words through machine translation; calculating importance of the words having undergone ambiguity elimination, and weighting a word order of the words; calculating a semantic distance of the words having undergone word order weighting, and calculating text similarity according to the semantic distance. By implementation of the method, the similarity of the short text can be calculated quickly and accurately.

Description

technical field [0001] The invention relates to the field of electrical data processing, in particular to a method for calculating the semantic similarity of short texts. Background technique [0002] Text similarity calculation is mainly to study and calculate the similarity between multiple texts, and it has a wide range of applications in many fields such as question answering systems and copyright detection. Common classification, clustering and other machine learning algorithms also involve the comparison of similarity between texts. There are many methods for calculating text similarity. The traditional method is based on the vector space model, and there are also improved similarity calculation methods based on semantics. [0003] No matter which calculation method is used, the following problems exist for short texts: (1) The content of short texts is usually relatively short, and after word segmentation, there is less information that can be used for similarity cal...
