For the problem of content-based information filtering, this paper introduces genetic algorithm to solve this problem, because it could find optimal solutions within global context. In order to illustrate the effectiveness of this approach, it gives a new approach based on set theory, and it also gives an experiment. From the theoretical proof and the experimental results, we could see that the method is feasible and could obtain better information filtering results. With the development of information technology, the Information world provides several network information to computer users, however, people are also inevitably exposed to a lot of spam, while they enjoy the convenience of information. Hence, the network information filtering arises at this historic moment. The text information filtering (Belkin and Croft, 1992; Liddy et al., 1994; Xuan-Jing, 2003) is a process that extracts the texts from a large amount of text stream in order to meet specific user requirements. ©2010 Academic Journals.

This paper researched an improved digital video watermarking algorithm based on relationship. The algorithm combines the video processing and video coding compression principle which adopts improved Arnold algorithm as well as the technology of the block and carries out a series of replacement process in the DCT coefficients of the video frame YCbCr spatial luminance Y components. Meanwhile, we segment information watermark image, aiming at the information watermark and mark watermark to be double embedded to improve the watermark embedding capacity and computing speed of the algorithm. Simulation results show that this algorithm can keep good invisibility of watermark. It has good robustness to video compression processing and special video attacks which can realize the blind extraction and random watermark detection. Copyright © 2015 Binary Information Press.

For mining useful data from mass data generated by Internet of things, analyses shortages of the traditional Apriori algorithm which has a lower mining efficiency and occupies the larger memory space. So, MapReduce model of cloud computing is introduced. In the mechanism of MapReduce, combine the architecture characteristics and key technology of Internet of Things, conduct distributedmining on data and information in environment of the Internet of Things, and the calculation model of distributed data stream mining is drawn. Performance analysis proves that the new data stream mining model overcomes difficulty of traditional data mining, and each link reflects the idea of distributed structure and improves mining efficiency obviously. © 2014.

The design of 3D model family in knowledge support framework has been recognized as an efficient means to realize sufficient 3D model variety to satisfy a range of customer demands. This paper proposed 3D model family modeling and design process based on FBS (function-behavior-structure) and API ontology, built the knowledge support design platform and framework, and described the knowledge-intensive design process. Finally, the prototype was developed for the actual design. © 2014 WIT Press. Source
