Big data technology plays a role in promoting the development of Internet video, and data has become an important carrier for users and network video platform to dig the effect of video communication, guide the video production, and master the user's behavior habits. This system establishes the conceptual process from data acquisition, data processing, data visualization. This article makes analysis...
With the completion of the human genome sequencing, a large number of data especially amino acid sequences floods into biological database. How to analyze these data quickly and even predict the structure and function of protein correctly have become hot topics in recent years. In this paper, we mainly study K-means clustering algorithm and KNN classifier in amino acid sequences of complicated data,...
With the rapid development of mobile smart phone and 4G network, online micro-video has come into the view of more and more people. The providers for the micro-videos hope that if they put their micro-video on a video website, they can get as much attention as possible. So it is becoming more and more meaningful to research the users' interest in different video websites. First of all, this system...
To address the lack of health status identification and poor stability problems in the rotating machinery equipment, this paper proposes a new method for health status identification of rolling bearing based on SVM and improved evidence theory. Firstly, in order to reflect the rolling health condition, we use the empirical mode decomposition (EMD) to extract energy value and the original part of the...
The existing opinion mining method based on adverbs about Chinese comments has lower precision rate and recall rate. For this problem, this paper redefined the narrow opinion word, and proposed an improved algorithm of Chinese comments opinion mining based on adverbs: In the extraction process of the feature words and opinion words based on adverbs increased conjunctions and negative words judgment;...
On the Internet, Deep Web information is hidden in the depths, the ordinary search engines cannot return them directly. In order to provide Deep Web information conveniently for users, a Deep Web information integration system should be set up. However, schemas of Web databases are not known in advance. Thus, it is an important task to extract information from the query interfaces and construct the...
Visual data mining techniques can display the process of data mining and results to the user graphically, which makes the user more perceptual and easy to understand the meaning of the mining process and its results and moreover it is very important in data mining. However, most of the visual data mining now is progressed with the result of visualization. At the same time, it is not suitable for the...
Many websites such as Yelp provide platform for users to write reviews about places they have visited. But not all reviews are equally useful. However, it generally takes from several weeks to months to receive feedback about “usefulness” of review from online community. So there is a need to automatically predict the “usefulness” of review. In this paper, we are trying to solve the specific question...
Classification rule mining is one of important areas of data mining, and it is a hot subject at present. In this paper, we introduce some definitions: relevant concept, pseudo concept, and relevant concept cover. Then we presents an algorithm to compute relevant concept cover, which divides the context into subsets, calculate the set of relevant concepts by the value of concept shannon entropy, and...
