Embodiment

[0050] Embodiment: An example of extracting Tibetan data from "Sina Weibo".

[0051] Step 1: Preprocessing

[0052] Firstly, the microblog data is obtained from the "Sina Weibo" platform, and the single microblog data is shown in Table 1.

[0053] Table 1 Weibo data example

[0054]

[0055] For the convenience of description, additional information items will be included in the description of the following data extraction A i Hidden, so the obtained Sina Weibo data contains 5 Weibo data a 1~ a 5, as shown in Table 2.

Abstract

A method for obtaining data from a new media platform and extracting thematic data of ethnic minorities is disclosed. According to the mass, unstructured and multi-topic characteristics of new media data, LDA model is used to extract features, analyze topics and mine hidden themes from preprocessed new media data. Then KG is constructed by using the domain knowledge of minority nationalities, andthe domain KG is used to guide the extraction of thematic data of ethnic minorities. In the process of extracting LDA model and KG guiding data, the invention sets parameters according to different data scales, thereby optimizing the algorithm and realizing accurate, efficient and expandable new media data extraction.

Description

technical field [0001] The invention discloses a method for acquiring data from a new media platform and extracting minority theme data. It involves a method of latent topic analysis and feature extraction based on latent Dirichlet Allocation (LDA) new media data, and using domain knowledge graph (KG) to realize the extraction of minority topic data. It belongs to the field of data processing and knowledge discovery. Background technique [0002] New media is a new media form relative to traditional media such as newspapers, radio, and television, including network media, mobile media, and digital TV. It is interactive and instant, massive and shareable, multimedia and hypertext, Features such as personalization and socialization. As new media play an increasingly important role in information dissemination, the processing and analysis of network media data has also attracted great attention from scholars at home and abroad. The data is divided according to the difference...
