Abstract
The invention provides a data processing method and apparatus based on a question-and-answer platform to solve a problem of low efficiency and precision of data mining. The method comprises: performing textual analysis on answer data acquired from the question-and-answer platform, and determining similarity of the answer data; according to correspondences, between problems and the answer data, recorded by the question-and-answer platform, clustering the questions corresponding to the answer data according to the similarity to obtain question clusters; and performing textual analysis on questions in each question cluster, and extracting relative word pairs composed of keywords of the questions in the question clusters, wherein keywords in a same question cluster are correlated. According to the invention, similarity analysis on the answer data can remove noise in the answer data, and reduce processing of irrelevant data in the answer data, and effectively quantify similarity of the questions, thus improving data processing efficiency and data processing precision.
Description
technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method based on a question answering platform and a data processing device based on a question answering platform. Background technique [0002] The question-and-answer platform provides a communication platform for users. Users can receive help from experts and other netizens on the question-and-answer platform, and at the same time try to provide effective help to other users. The content of the question-and-answer platform is generated by users. After statistics and mining, valuable information in various aspects can be obtained. [0003] When mining related entities based on the Q&A platform, it usually extracts related questions on the same topic in the Q&A platform, and then mines related entity information based on the answers of different users to the same question. For example, on the topic of electric vehicles, for question 1 on the qu...
