Problems solved by technology

Among them, user-based social labeling has the problem of cold start in the early stage of system service because there is no past data for reference; multi-label classification and labeling methods are mostly based on supervised learning algorithms, which require a large number of manually labeled data sets as Training sets and manual labeling data sets are not only time-consuming and laborious, but also have a lot of subjectivity

Abstract

The invention discloses an automatic annotation method and system for an innovative and creative label on the basis of big data. The method comprises the following steps that: using a Sogou corpus to train Word2vector and LDA (Latent Dirichlet Allocation) to obtain a training result set; carrying out word segmentation on the document data of a user browsing page, removing a stop word, and carrying out word filtering processing; for preprocessed document data, combining an improved TextRank algorithm with the Word2vector to calculate a label from the text data; in addition, carrying out calculation on the preprocessed document through the LDA to obtain the label related to a document data theme; and through a label cloud generation way, realizing visualization, and annotating all text label words in the document data so as to bring convenience for users to read and find key content parts.

Description

technical field [0001] The invention relates to a method and system for automatically marking innovative and creative labels based on big data. Background technique [0002] With the rapid development and popularization of the Internet, the explosive growth of information has resulted in the accumulation of a large amount of information on the Internet. At the same time, Internet users are not only browsers of Internet content, but also create various information on the Internet, which leads to the diversification of Internet information forms, which makes information screening very difficult. Information with text as the carrier of Internet information accounts for a large proportion. The increase in the amount of information and the confusion of the structure make people have more references in the process of searching for information, and the coverage of information is more comprehensive. All aspects of life have greatly facilitated people's lives, but a large amount of ...
