摘要：
Similarity measure of fuzzy sets can boils down to distance nearness and "shape" similarity of two fuzzy sets, and distance nearness of two fuzzy sets can be regarded the question of least value of some function with some norm, and similarity measure can be defined the optimum factor of proportionality. Mutual subsethood theorem proposed by Kosko or Wang is the optimum factor of proportionality with l/sup 1/-norm. We construct some new similarity measure by the optimum factor of proportionality with l/sup 2/-norm.

摘要：
Association rules mining is an effective method to extract hidden knowledge in databases that is used widely in intrusion detection. But it causes the sharp boundary problem in handling databases with quantitative attributes. To solve the problem, a method is presented that integrates fuzzy sets and genetic algorithm in anomaly detection. Encoding the parameters of membership functions into an individual (chromosome) and embedding the fuzzy association rules mining techniques into the genetic optimization, an optimal parameter-set can be obtained. With the use of the parameter-set in anomaly detection, the normal states of protected system can be differentiated from the anomalous states to the largest extent, and the veracity of anomaly detection is improved significantly.

摘要：
Integrating with ontology and XML Schema, taking advantage of Web Service, this paper develops a service oriented information representation architecture-SOIRA to solve the semantic heterogeneity of distributed and semi-structured information. It introduces a mediated semantic schema. originating from ontology to XML Schema, discusses the multi-matching strategy between the mediated schema and source schemas. The implementation of SOIRA with two kinds of semantic representation services are presented at the end of this paper, which enable interoperability, translation of information, and queries across the representations as well.
摘要：
The formula of a similarity measure defined by σ-entropy is simplified depending upon universal calculate formula of σ-entropy, and prove two important propositions by this formula. Our conclusions lay a foundation of answering the problem that not be solved by Liu.
摘要：
In this paper, we designed a Electrical Power Management Information System(EPMIS), which facilitates a integrated retrieval of data from several distributed database on the network. We propose the EPMIS structure which relies on a global replicated data and a local information database. And several key techniques in the EPMIS are illuminated.
摘要：
Based on ideal absolute errors and relative errors, a new grey model-GM{sup}p(1,1) model is presented. The existence problem of its solution is also solved based on a few conditions. Then MGM{sup}p(1,n) model is presented. These optimized models GM{sup}p(1,n) and MGM{sup}p(1,n) have good anti-noise property to absolute and relative errors. Examples illustrate that they have very good fitting and forecasting results.

摘要：
It is well known that the similarity measure can be induced from entropy of fuzzy sets, we prove that this existing kind of similarity measure all satisfies the proposition, that is, the similarity measure of two fuzzy sets equals to that of their complementary sets. But the mutual subset hood does not content this proposition. We construct a new kind of similarity measure depending on entropy, and it doesn't meet this proposition.

摘要：
Almost present similarity measure of fuzzy set is rooted in the relation of equivalence of the equality of sets. A fuzzy set can be considered a vector, and make use of the equality of two vectors, we propose a similarity measure of two fuzzy sets, which do not meet the relation of equivalence of the equality of sets.
