Conceptual hierarchy represents the relationship between objects or concepts in a hierarchical form. The work presented here focuses on creating hierarchies which have a relationship between parent and child nodes but not between siblings. When we evaluate or classify certain objects (e.g., service quality), we often use a conceptual hierarchy which has various items (concept) at its nodes. If the...
There are a large number of accessible deep Web sites on the Internet. However, even if identical entity has different representation formats on different Web sites. So entity identification plays a crucial role in deep Web data mining. This paper proposes an entity identification method in the field of Chinese books. First, using improved Jaccard coefficients to calculate similarity of text attributes...
Since 1996, land detailed investigation project and the second-time land resources survey and monitoring project have been developed one after another. The methods of land resource management have been a shift from the traditional manual method to the modern information means, as the corresponding information technology has been utilized in processing, statistics and updating the database, of which...
The data mining of E-commerce is to extract implicit, valuable business and understandable information from vast information to guide future business activities. As an important branch of data mining, grey relational clustering has become a hot research spot in the field of data mining because its form is simple, easy to be interpreted and understood, and it describes the important data relationship...
According to production statistic work for coal enterprise developing present situation and actual application situation in our country now , the production statistic system for coal enterprise, based the C/S and B/S unify composite structure model, has been proposed in this paper. The system use the exploitation method of combining SAD and object oriented. It has realized many essential functions,...
Factor analysis is a statistical method used to uncover relationships among many variables. Factor analysis could be used to separate the information gained about the interdependencies variables, helping reduce a large number of variables to a smaller number of factors for modeling purposes. It is becoming more and more popular in socio-economics statistics. This paper, based on mathematical statistics...
Ensuring public security is an important issue for every government, and effective public security depends on the efficiency of criminal justice processes and procedures. The procedures of the criminal justice may be viewed as the upper-, middle-, and down-stream sections of a supply chain. Like their business counterparts, most law enforcement agencies have to deal with logistics, information flow,...
In order to realization electronic parts product appearance quality detection control, one kind of processor based on the intelligent knowledge automatic extraction and system intelligence modeling was presented. In the processor, wavelet-fuzzy technique and neural network technique are combined. Uses the fuzzy wavelet extraction image feature, and wavelet function is used as fuzzy membership function...
