The vertical association rules mining algorithm is an effective mining method recently, which makes use of support sets of frequent itemsets to calculate the support of candidate itemsets. It overcomes the disadvantages that Apriori and its relative algorithms produce large amount of candidate itemsets and require scanning database many times. The vertical association rules mining algorithm needs...
The new method of active fortify organizing a supervised area based on color and geometric feature is proposed in this paper. By the basis of color feature in the real supervised scene, in the first instance extracting several regions of interest (ROI) with noise, then matching with geometric shape by Fourier descriptors in the database, sequentially achieving automatic organizing a supervised area...
When studying attribute reduction, we need to enumerate all the minimal reductions to prove the correctness of the attribute reduction algorithm. The explosion of attributes combination makes time complexity of the enumeration algorithm pretty high. An algorithm derived from grouping the rows of decision table is put forward to validate if an attribute set is reduction. Based on this algorithm, a...
A new method of decision support system (DSS) is put forward, and the theory of immune arithmetic and agent is applied in the scopes. Based on immune agent, a decision support system of urban river water pollution control based on immune agent is proposed. The system includes apperceive agent, control agent and response agent, which solves the problem that DSS can not acclimatize itself to dynamic...
In this paper, some unique features of fuzzy object-class relationships, which do not occur in classical object-oriented databases, are investigated. We identify direct object-class relationship, indirect object-class relationship, and arbitrary object-class relationship in fuzzy object-oriented databases. In particular, soft computing methods are developed in the paper to quantitatively determine...
Owning to the expansion of network scale and complication of network construction, it has a big challenge to previous network monitoring technology. After analyzing the network monitoring technology and IA (intelligent agent) technology, in this paper, a method based on IA is proposed to complete dynamic network monitoring, developed by a cross-platform language Python, including two monitoring modes:...
Grid has attracted great attention of researchers during the past years. With its developing, it has coped with an increasing amount of complicated data and huge heterogeneous databases. So it is indispensable to develop a middleware that could access and integrate heterogeneous databases. Therefore, we propose a new fundamental architecture of the heterogeneous database access and integration in...
Conceptual data models, being the tool of design databases, have been proposed. Information in real world application is often vague or ambiguous. Currently, less research has been done in modeling imprecision and uncertainty in conceptual data model. The UML (Unified Modeling Language), being a set of OO modeling notations and a standard of the Object Management Group (OMG), can be applied for many...
Nowadays, the number of Web databases has experienced an increase at a surprising rate. Data in the Web databases are hidden behind query forms. As the general reptiles are difficult to search these data, massive resources have been wasted. In order to integrate Web databases and provide a convenience to users' query, one of important problems in this research area is to understand what a query form...
As complex and varied concrete structures and their disease characteristics, it is difficult to extract a stable identification feature. Interpretation of the ground penetrating radar(GPR) scanned image is mostly based on experts experiences. Thus we designed an efficient concrete bridge disease identification system based on sample database(CBDI). The CBDI is based on principal component analysis...
With the rapid development of the Internet and communication technology, huge data is accumulated. Short text such as conversation in chatting room and email is common in such data. It is useful to cluster such short documents to get the structure of the data or to help building other data mining applications. But most of the current clustering algorithms can not get acceptable clustering accuracy...
With the general use of Information Management System, log management is more and more important. After analyzing the requirements of log service on large-scale information management system, the idea of specialization, high reliability, easy to operate and manage comes out to sort the problem of limitation on current log management kit. The paper??s main idea is to achieve specialization, practical...
Collaborative design is a new design style for mechanical manufacture. It can help designers of different places complete the same design project at the same time. It is an important problem to select a suitable partner for the collaborative design project from the partners. A fuzzy analytic hierarchy process (AHP) methodology is presented for the partner selection, which provide a multi-criteria...
Contemporary multi-dimensional database technology is severely limited at managing indexed data types of keys for many advanced application. Here, we present an elaborate retrieval method to extend the traditional R-tree, and we call it Generalized R-Tree(GRT). It can serve as an indexing structure in some multi-dimensional database systems. This method mainly addresses the problem of that traditional...
Hydrological parameters play important roles in designing new well. Dupuit formula and Theis formula are usually used to calculate hydrological parameters by insert numerical method. The precision of parameters is affected by insert numerical table and pumping test data of reference wells. Purpose of this paper is to study on utilizing these data efficiently. Firstly, database of water resource is...
With the rapid development of Internet in the world, E-commerce has become a new research field, and the digital copyright protection in E-commerce has also become a big concern of society. The conventional method of copyright protection is to search information of digital works with search engine, and download them to a server where all digital works would be authenticated. In this paper a new copyright...
Based on the analysis of the heterogeneous data environment, the system integration platform is built to resolve the heterogeneous data sharing and mutual visit in view of the status quo of the heterogeneous data and integration demand in the coal enterprise. The system chooses the integration project based on the middleware, constructs the heterogeneous data integration frame based on the XML, gives...
Government business model (GBM) is used to depict business processes of governments. It includes three basic models, which are process model, organization model and resource model. But these three models can not depict the collaboration relation between the infrastructure elements (including organization model elements and resource model elements) or the information flow in a government business process...
At present, storing XML document in a relational database is a hot topic because relational databases are mature and scale well. In this paper, a novel relational database storage structure that can store XML document is proposed. An algorithm that translates XML document to relational database is given according to the proposed storing structure and algorithms that translate XPath Query to SQL Query...
To make function test of Web application based on struts automation, an automated test tool is proposed. The content of form is produced through analyzing Web page by HtmlParser. The test cases are produced by matching the data in test database and the content of form. The test cases are described by XML. Changing the test cases to code of Cactus and running the code to achieve the target of testing...
