Text classification is an important task of data mining. Existing algorithms, which based on vector space models, does not considered concept similarities among words, so the accuracy of traditional text classification cannot guarantee. To solve the problem, this paper proposes a new text classification algorithm in Chinese text processing based on concept similarity. The contributions of the paper...
We propose an algorithm for extracting fields from HTML search results. The output of the algorithm is a database table - a data structure that better lends itself to high-level data mining and information exploitation. Our algorithm effectively combines tree and string alignment algorithms, as well as domain-specific feature extraction to match semantically related data across search results. The...
Recently, mining negative association rules has received some attention and proved to be useful. To the best of our knowledge, three typical forms for negative association rules and three corresponding mining methods have been proposed. However, the existing forms are not general enough, and can not represent some special cases in the real world. In this paper, an extended form for negative association...
