The Research And Design Of Text Calculation System Based On WEB

With the rapid development of computer technology and the popularity of the network, the era of Information Explosion has come. However, we enjoy the wealth of information and convenient life brought by the internet, we also bear the plague of the Information Explosion. Faced with the complex and endless information, how can people derive beneficial information, has become the main topic of current research. Currently, the study of information processing is focused on the theoretical study, and the effective information filtering system is not mature. Therefore, most researchers in different fields and companies all have the urgent requirement for a system which can provide for the different requirements of a computing system for the text features analysis.The system is mainly based on the actual needs. To create the separate database repository for different users, I use the stored procedure in the database. And it also realized the design based on cloud platform. To analyze and calculate the text features, I use the maximum forward matching algorithms for the text segmentation operate, and use lots of features like Term Frequency, Term Frequency & Inverse Document Frequency, Information Entropy, Term Distribution Entropy, Document Distribution Entropy, Pearson Correlation Coefficient and so on. I use the multiple feature and power spectrum matching algorithm. Compared with the traditional algorithm, it is more accurate and more intuitive.The system uses B / S architecture model, using SQL Server 2012 database to store data and using SSH open-source framework for system development. To invoke MATLAB in Java I use the access mode of COM object and to draw the power spectrum I use the technology of JFreeChart, at last it is displayed in the internet. In this paper, I made a system requirements analysis, outline design and detailed design based on the software development. At last, I also described the results of testing and maintenance.In this paper, a simple system requirements analysis and software development process based on the system of the outline design, detailed design, and the system was simple test and maintenance.In conclude, there is some innovations of this paper. Above all, this system combines a variety of text mining algorithms and achieves text similarity calculation by calculating eigenvalues. Secondly, the similarity calculation based on public and private cloud. Finally, the analysis and match of power spectrum is also the innovation of this article.
