Hot Topic Real-Time Detection Technology Study And Application

With the rapid development of the Internet, social network platforms and mobile technology, people prefer to share their own views on the Internet. The hot topics is what people are concerned and talk about every day. Hot topics can play an important role in the political, economic, cultural and other fields. Therefore, it is very meaningful to study the hot topics. In this paper, the author will introduce how to build a hot topics real-time detection system and related research.The main works are as follows:Firstly, the author designed and completed a hot topics real-time detection system to view details of hot topics;Secondly, the author proposed a crawler technique based on template to collect the web news and microblog data. The crawler was applied in information collection model and can collect data efficiently; Thirdly, the author proposed a Chinese segment technique based on word frequency and the technique was applied in pre-processing model. It can solve the ambiguous words problem and get more accurate results;Finally, the author proposed a quasi-maximum clique algorithms to combine the similar topics, and it was applied in topic extraction module. The algorithm is able to get more accurate topics.The system discussed in the paper can efficient collect data from news and microblog, complete text pre-processing and extract topics. Finally, results are shown on the display platform. As a result, the system has a good application value.
