A relative effective approach to calculate the Choquet integral of fuzzy-valued function with nonmonotonic fuzzy measure is proposed. Base on the connection between the Choquet integral value of the real-valued function and the Choquet integral values of its order-preserving functions, it is shown that the minimum and maximum of the integration of interval-valued function must be reached by ones of...
An axis-parallel k-dimension box is a Cartesian product R1 × R2 × ... × Rk, where each Ri is a closed interval of the form [ai, bi] on the real line. For a graph G, its boxicity(denoted by box(G)) is the minimum dimension k such that G is representable as the intersection graph of axis-parallel k-dimension boxes. Let each Ri be of the same length, then the k-dimension box is a k-dimension cube. When...
In the process of concept design of bridges, it is necessary to select the best from feasible alternatives through comparison and filter. The criterion set, used to evaluate and select the satisfying alternative, consists of many qualitative and quantitative factors. Therefore, the selection is a problem of multi-criteria and semi-structural decision making. Different from traditional methods in semi-structural...
Along with the technology and society's unceasing development, the regarding regional economies' promotion effect's research of highway construction investment entered the new stage. This article focused on the region influence appraisal after highway project investment in the entire life cycle which involved to it proposed a kind of new computation models, this model by conformity fuzzy analytic...
How to construct Web ontologies has become a key technology to enable the Semantic Web, especially constructing ontologies by extracting domain knowledge from database model. However, classical ontologies are limited to crisp concepts and may not be sufficient for handling fuzzy information found in many real-word application domains. Considering the difficulty of generation of fuzzy ontology using...
High in situ stress and some geological disasters induced, such as large deformation, are well known as the complex engineering problem which often happen in tunnel construction. Large deformation can bring great threat to tunnel safety during construction and operation, but so far there is no concrete and applicable methods for the prediction of large deformation, it needs to to further developed...
This Energy is one of the important factors in the economic development. People pay increasingly attention to the energy security which is especially taken seriously by the government to ensure the normal running of the economy. The paper uses set pair analysis and fuzzy approach to evaluate the security status of the oil, coal and natural gas subsystem and finally the whole energy system. The case...
In order to solve the problem on evaluation of road schemes which is affected by many factors, through all the influence factors and the technical features were comprehensive analyzed, the evaluation model was set up which was based on the fuzzy mathematics and the analytic hierarchy process, and the expert evaluation method was also used. First the hierarchical structure of the road scheme evaluation...
The stability evaluation of the central pillar between twin neighborhood tunnels is an important step in a tunnel construction process. In this paper an indicator system was proposed to evaluate the stability state of the central rock pillar between twin neighborhood tunnels; then an AHP (Analytic Hierarchy Process) model was constructed to calculate the weights of indicators; and finally, with fuzzy...
On the base of the research and summarization of the pedagogical exercitations of vocational business Japanese major of Eastern Liaoning University, the pedagogical exercitations quality of business Japanese major is evaluated comprehensively in the article, by taking use of models and level analysis of multi-level fuzzy comprehensive evaluation. According to actual characteristics and relative documents,...
Finding frequent itemsets is one of the most important issues in mining data streams for many applications such as web click stream mining, sensor networks, and network traffic analysis. Most prominent algorithms for traditional transaction databases need multiple scans, therefore, they are not suitable for data streams which are continuous, unbounded, usually come with high speed. In this paper,...
To deal with the problem of too many answers returned from a Web database in response to a user query, this paper proposes a novel categorization approach which takes advantages of the user contextual preferences to construct a navigational tree in order to reduce the information overload. Based on the user original query, we first speculate how much the user cares about each attribute in the specified...
The accuracy and fairness of the assessment results to a large extent limited by the choice of methods of assessment data processing. In the current practice of the equipment support core competencies (ESCC) assessment, there are two methods of assessment data processing mainly used, which are named the simple arithmetic average method and the weighted arithmetic average method. In this paper, an...
This paper introduces the basic conceptions of metadata and ontology, analyzes process and relations between them. By employing the semantic logic ability of ontology to the enterprise metadata information system, it indicates ontology dominance in mutual operational of metadata. On the basis of establishing enterprise metadata information resource domain ontology, the author elaborates idea of metadata...
Based on the analysis of the existing opinion mining techniques, mining accuracy and complexity, this paper proposes a opinion mining system which mines useful opinion information from camera reviews by utilizing Semantic Role Labeling (SRL) and polarity computing method. Feature lexicon and sentiment lexicon are constructed to mine features and emotional items. In the end, the comparison between...
The explosive growth of the Internet inevitably leads to the proliferation of harmful information such as pornography, drug and violence. A great deal of filtering techniques based on image and text categorization is proposed in the literature. Among them, text-based filtering plays a leading role for its good performance. Existing text filtering algorithms can be seen as a classical text categorization...
Service discovery is the premise of service composition. The existing service discovery methods only consider individual service functions and static properties, less considering the inherent dependencies between the composite services. The data dependencies between services reveal the logic correlation between the composite services, but it is of great significance for the service composition and...
The granularity is used to describe decision knowledge based on the concept of rough degree in rough theory. The rule distance are put forward, and a feasible distance formula between different rules is constructed according to the requirement of describing the distance between different rules and the definition of attribute signification in information system. Both of the n-dimensional knowledge...
In tunnel advanced detection, it will use FEM and physical experiment to simulate the anomalous characteristics of the new DC resistivity method of focus-current. Firstly, the principle and electrode arrangement will be introduced in the paper. Secondly, it makes an analog calculation to several relatively typical geoelectric models which apply the finite element method with solving anomalous potential...
This paper describes the active statistical map of cartographic concepts and application requirements, focusing on analysis of active statistical map-making process used in the structural design of the knowledge base, the use of knowledge classification and knowledge of decomposition and renewal strategy, which uses a Bayesian probability model as a knowledge filter model for the screening, and analyzes...
