We propose the system that offers only the article that is the relation to topics to the user in this research. When the user wants to read the article that is the relation to topics, the user must click the link to the article. Therefore, it is difficult for the user to read only the article related to topics. Moreover, there is the article that is similar to each other content or article. Therefore, user must read the article that is similar to other article. We propose the algorithm to find similar articles. For the proposed system, we use the feature of reported articles. There is an outline of the entire article

In this paper, we propose the technique of the sen- sor data mining by the P2P (Peer-to-Peer) network. The mechanism that it is possible to share on the P2P network is considered by receiving information from the sensor by the P2P application. Searching request for sensor unit and mining the sensor data does on the P2P application. We consider that the proposed technique is applied to the school environment mea- surement system. In its system, sensor units are ar- ranged on campus, user can measure room's temper- ature and humidity. The temperature sensor and the humidity sensor are implemented in a microcomputer board that can connect to the Internet, and we define the microcomputer board as a sensor unit. We con- struct the P2P sensor network on which a PC accesses the sensor unit and P2P application on its PC uploads on the P2P network. The P2P network becomes possi- ble disclosing sensor information after more advanced processing is given by thinking as P2P application not the sensor unit but on the sensor unit and PC.
