Problems solved by technology

[0006] However, the current instruction analysis and instruction recognition technology is not accurate enough for user instruction analysis, and the post-processing based on the conclusions obtained by this inaccurate analysis and recognition technology will also produce large deviations.

Embodiment 2

[0063] Embodiment 2 is similar to Embodiment 1, except that the step S3 adopts the following method:

[0064] Calculate the support factor S(support) of the ambiguous field, and determine the segmentation result according to the comparison result of the support factor. For example, there are two segmentation results for the ambiguous 123 field: 1 / 23 or 12 / 3, and calculate at this time And compare the two support factors:

[0065]

[0066]

[0067] In the above formulas, S(123) is the probability that field 1, field 2, and field 3 appear simultaneously in this information base, S(12) is the probability that field 1 and field 2 appear simultaneously, and S(23) is the probability of field 2 The probability of appearing at the same time as field 3, the information base is a database for storing the collection of historical command information and command identification information. If S(1 / 23) is greater than S(12 / 3), the first segmentation result is selected as the final se...

Abstract

The invention relates to an instruction identification method. The method is characterized by comprising the steps of S1, performing segmentation on an instruction by adopting two methods to obtain two segmentation results; S2, judging whether the segmentation results are the same or not; S3, determining ambiguous fields and eliminating ambiguity to obtain final segmentation results; S4, performing index quantification on the final segmentation results to obtain keywords; S5, performing matching on the keywords and a classification association table; S6, judging whether each keyword can be matched with categories in the classification association table or not; S7, classifying the keywords which cannot be subjected to matching; and S8, determining a final category of the instruction. According to the method, the instruction of a user search request is identified; and by performing word segmentation processing on the user search request, the keywords are extracted and search requests are subjected to classification processing, so that the category that the user search instruction belongs to can be obtained and current user demands can be obtained.

Description

technical field [0001] The invention relates to the field of data classification, in particular to an instruction recognition method and system. technical background [0002] With the continuous development of real-time marketing, the analysis of user needs has become an extremely important part. By semantically identifying user search requests, analyzing and mining their requests, and obtaining the current needs of users, it is possible to push relevant content to users in real time. [0003] Semantic recognition is to perform word segmentation processing on the text of the user's search content, obtain valid keywords and classify the keywords, and then obtain the category of user needs. [0004] The so-called word segmentation is to divide the sentence into individual words. It is the process of recombining consecutive sentences into word sequences according to certain norms. Taking Chinese word segmentation technology as an example, the goal of word segmentation techno...
