Embodiment 1

[0024] An embodiment of the present invention provides a method for automatically adding tags to short texts, such as figure 1 As shown, the method includes:

[0025] Step 101, counting the reciprocal document frequency of each tag word in the tag word set;

[0026] Optionally, a set of tagged words and corpus associated with the set of tagged words are preset; generally, large-scale language instances may not be observed in statistical natural language processing. So, people simply use the text as a substitute, and take the context in the text as the context of language in the real world. A text collection can be called a corpus (Corpus). Optionally, relevant texts are collected from the Internet, for example, the question-and-answer content in Tencent's "Wanwen" product can be used as the corpus.

[0027] Segmenting the corpus; segmenting a sentence into individual words, for example, segmenting the sentence "This is a method for automatically adding tags to short texts",...

Embodiment 2

[0057] An embodiment of the present invention provides a method for automatically adding tags to short texts, such as image 3 As shown, the method includes:

[0058] Step 301, preset the set of tagged words and the corpus associated with the set of tagged words;

[0059] Optionally, according to requirements, obtain a set of tag words. For example, if you want to add tags to film and television content, you need to collect a set of commonly used tags for film and television, including film and television genres, stars, and so on.

Abstract

The invention discloses a method and a device for adding tags to short texts automatically and relates to the technical field of the Internet. By the aid of the method and the device, the tags can be added to the short texts automatically, and the accuracy of the added tags is improved. According to the method and the device, through statistics of inverse document frequencies of various tag words in tag word sets, the short texts are extended into long texts, word frequencies of appearance of the various tag words of the tag word sets in the long texts are determined, and according to the inverse document frequencies and the word frequencies, the text tags of the short texts are determined. The method and the device are applicable to adding of the tags to the short texts.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and a device for automatically adding labels to short texts.
