Problems solved by technology

Traditional text classifiers represent text as a collection of words, regardless of the position and dependencies between words, and are not effective when applied to the problem of dividing sentences into "comparative" and "non-comparative".

Embodiment Construction

[0035] An embodiment of the present invention provides a method for generating a Chinese comparative sentence classifier model. By processing a data set containing several marked Chinese sentences, a comparison pattern set and a Chinese comparative sentence classifier model are obtained. Its flow chart is as figure 1 As shown, its execution steps are as follows:

[0036] Step S10: Read in a sentence from the data set in sequence.

[0037] All sentences in the dataset have been manually annotated with their categories.

[0038] Step S11: Using automatic word segmentation and part-of-speech tagging techniques / methods, segment the read sentence into several words, and add a part-of-speech tag to each word.

[0039] For example: using the existing Chinese word segmentation software, it is possible to divide each sentence into several words, and add a part-of-speech identifier for each word.

[0040] Taking the sentence "INTEL has a price advantage over AMD" as an example, the s...

Abstract

The invention discloses a method and a device for generating a Chinese comparative sentence sorter model and identifying Chinese comparative sentences. The method comprises the following steps: converting each clause containing set comparative keywords in each sentence of a data set into a sequence, and establishing a category tag as the same as the sentence of a corresponding clause for the sequence; obtaining a sequence set; mining a plurality of comparative modes from the sequence set by a sequence mode mining algorithm, and forming a comparative mode set; matching each comparative mode in the comparative mode set with each sequence one by one, and according to the matching result and the total number of the comparative modes, obtaining a group of characteristic vectors corresponding to each sequence; generating a sorter model according to the characteristic vectors and the corresponding category tag of the sequence; and then identifying a read-in sentence with unknown category through the obtained comparative mode set and the sorter model, and determining whether the sentence is a comparative sentence. By automatically learning the mode characteristics of the comparative sentences, the sorter model is generated and can automatically and effectively identify the comparative sentences in a text.

Description

technical field [0001] The invention relates to the technical field of intelligent information processing, in particular to a method and device for generating a Chinese comparative sentence classifier model and automatically identifying Chinese comparative sentences. Background technique [0002] With the rapid development of the Internet, Chinese information has also shown explosive growth. Among them, a lot of information involves the comparison of various things, such as comparison and recommendation of similar products. Automatically identifying such comparative information is of great practical value. By automatically detecting comparative sentences in articles, it provides a prerequisite for accurately extracting compared entities and the relationship between entities. [0003] The study of comparative sentences in the field of traditional Chinese linguistics started earlier. Regarding the definition of comparative sentences, Ma Jianzhong pointed out that "the same ...
