[0027] In order to solve the problem of low work efficiency and low accuracy in the prior art, the classification of information is usually carried out manually, the embodiment of the present invention discloses a text information classification method and system, according to the preset The rule extracts the keyword information set from the acquired text information to be classified, and matches the key words of the text information to be classified according to the extracted keyword information set and the corresponding relationship between the preset sample keyword information set and the text classification information. The text category information corresponding to the word information set, and finally classify the text information to be classified according to the text category information, so as to realize the automatic classification operation of the text information, greatly improve the work efficiency, the accuracy of classification, and so on.

[0066] Please refer to figure 2 , figure 2 This embodiment provides a flow chart of processing for users to classify using a text information classification method through a client.

[0067] This embodiment is a text information classification method combined with the client and specific application scenarios, and its processing steps are as follows:

[0068] S201. Acquire sample text information on the client, mark and classify it, and establish a correspondence between sample keyword information sets and text category information.

[0069] In this step, text information is collected in order to create a text category keyword information set, and the collected text information is used as sample text information for creating a keyword information set. The text information can be historical text received by the client before The information may also be some applications that have been classified and processed before, short messages, chat text messages, etc. on the terminal,...

[0125] Please submit Figure 6 , Figure 6 The processing flowchart for classifying a single piece of text information provided in this embodiment, the processing steps are as follows:

[0126] S601, inputting a single piece of text information, for example, inputting a single piece of text "to have dinner in the presidential private room of Jinling Hotel tomorrow night."

[0127] S602, perform word segmentation on the input text information, and perform word segmentation on the text after removing punctuation marks: "tomorrow / evening / Jinling / restaurant / president / private room / dinner / ".

[0128] S603, each text is split into multiple words, and the above text is split into multiple words: "tomorrow", "evening", "Jinling", "restaurant", "president", "private room" and "dinner".

[0129] S604, extracting keywords from the text information, and performing vectorized analysis with category keyword information sets in the system, where existing keyword information sets are represe...

Abstract

The embodiment of the invention provides a text information classification method and device. According to the method, a sample keyword information set of a text category is set in advance, and a corresponding relation between the sample keyword information set and text category information is established, so that a matching foundation is provided for subsequent classification of to-be-classifiedtext information; and during classification processing of the to-be-classified text information, keyword information is extracted from the to-be-classified text information according to preset rules,and the text category information corresponding to the to-be-classified text information is obtained through matching according to the corresponding relation between the sample keyword information setand the text category. Through the information classification mode, it is only needed to perform system automatic matching, classification processing efficiency is greatly improved, the analysis cycle is shortened, a manual allocation error is lowered, and matching accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of text information classification, in particular to a text information classification method and a device thereof. Background technique [0002] With the development of information classification technology, the information processing departments in various enterprises receive or accumulate massive amounts of information every day. In some cases, it is necessary to extract a certain category of information from the information, but due to There is no direct corresponding relationship established, therefore, it is impossible to directly use search engines to retrieve and extract. The existing methods for categorizing information usually use a manual method to analyze item by item, which will cost a lot of manpower. At the same time, with the continuous increase in the amount of interactive information, or the continuous increase in the accumulation of related work every day, at this time, if the information...
