The main thrust of this paper is application of a novel data mining approach on the log of user' s feedback to improve web multimedia information retrieval performance. A user space model was constructed based on data mining, and then integrated into the original information space model to improve the accuracy of the new information space model. It can remove clutter and irrelevant text information and help to eliminate mismatch between the page author' s expression and the user' s understanding and expectation. User spacemodel was also utilized to discover the relationship between high-level and low-level features for assigning weight. The authors proposed improved bayesian algorithm for data mining. Experiment proved that the au-thors' proposed algorithm was efficient.

Aiming at the problems existing in the traditional power grid information security access system, such as poor data processing timeliness, low recall rate and low information filtering accuracy, a power grid information security access system based on improved bayesian algorithm is proposed. In the part of hardware design, the data source layer, data acquisition layer, data access layer, data storage layer, bus layer, application support layer and application layer are designed from bottom to top according to the idea of layered design, and the application support suite and main function modules of the system are developed. In the part of software design, the traditional bayesian algorithm is improved, and the improved algorithm is used to construct the internal information filter of the power grid, which is applied in the information security access system to realize the security access of the internal information of the power grid. The experimental results show that compared with the traditional system, the information security access system based on improved bayesian algorithm has better data processing timeliness, higher recall rate and higher information filtering accuracy, and its application advantages are more obvious.

As information on the Internet expanded rapidly, we can get more information than before. However, how to find user-intended information from the Internet include text, images, videos isn't easy, In this paper, we use relevant feedback and build user space by improved bayesian algorithm to mine the log of user's feedback to improve retrieval performance. Data mining is used to remove clutter and irrelevant text information, and help to eliminate mismatch between the page author's expression and the user's understanding and expectation.
