Embodiment Construction

[0021] Embodiments of the present invention are now described with reference to the accompanying drawings, as figure 1 , the present embodiment takes two short texts S1 and S2 as an example to illustrate the short text similarity calculation method based on the number of retrieval results, including the following steps:

[0022] Step S1, preprocessing short texts with a length less than or equal to 200 characters, the specific steps are

[0023] Step S1-1, using a common stop words list (stop words list) to filter the short text, the common stop words are modal particles, adverbs, prepositions and conjunctions;

[0024] Step S1-2, filtering the endings of word segmentation transformation forms of each word forming the short text, extracting word stems, and calculating the word frequency of the word stems.

[0025] In step S2, a single short text and a pairwise combination of short texts are respectively submitted as search query words to a large-scale corpus, and the corpus u...

Abstract

The invention discloses a short text similarity computing method based on the searched result quantity, which includes the steps: 1 preprocessing short texts; 2 utilizing single short texts and combinations of each two short texts as search words and respectively submitting the search words to a large-scale corpus; and 3 computing similarity between each two short texts by the aid of the returned searched result quantity. The computing method does not depend on traditional text processing and is capable of quickly and effectively obtaining computed results. The short texts are utilized as the search words, and the large-scale corpus returns searched results including the short texts. Content of the searched results includes text interpretations on the short texts, and the searched result quantity can be regarded as a compressor and implies semantic interpretations of the short texts in the corpus.

Description

technical field [0001] The present invention designs short text similarity calculation, specifically refers to a short text similarity calculation method based on the number of retrieval results, and belongs to the field of text mining. Background technique [0002] Short text (Short Text) refers to those short text forms, which have a wide range of extensions, and more and more communication platforms use short text more frequently, such as mobile phone short messages, instant messages, BBS titles, Weibo, online Chat records, blogs and news comments, etc. At present, the amount of short text data is increasing day by day, and the text mining of short text has broad application prospects in the fields of topic tracking and discovery, buzzword analysis, public opinion early warning, and image retrieval. [0003] However, due to the short text length of short text, its sample features are very sparse, which is not conducive to retrieval analysis. In addition, short texts are...
