    Networked software (NS) is a kind of online software produced by linking information resources on the Web with the help of intercommunication and cooperation between networks and users. Due to the complexity of NS, requirements engineering is now emerging as a critical issue in it. In the user-driven and networked-resources oriented environment, how to capture highly variable non-functional requirements become more and more important. In this paper, a context awareness non-functional requirements metamodel based on ontology is proposed, which introduces knowledge and rules provided by domain ontology to induce non-functional requirements in specified domains. So it can be used to establish meaningful semantic relationship between non-functional and context information, help users to complete their non-functional requirements to some degree, and finally support automatic detection of software requirements.

    The measurement of semantic similarity is a foundation work in semantic computing. In this paper the authors study the similarity measure between two words. Different from previous works, this paper suggests a novel method that relies on machine-readable dictionaries for measuring similarities. Machine-readable dictionaries are more widely available than other kinds of lexical resources. If two words have similar definitions, they are semantically similar. A definition is represented by a definition vector. Each dimension represents a word in the dictionary. The score of each dimension in the vector is calculated by a variation of tf*idf. Evaluations show that this method achieves competitive results in both Chinese and English. View full abstract»

    The traditional information annotation technology is usually based on text description methods. With the ever increasing multimedia resources and the rapid progress of cross-media technology, the annotation between different modalities of media information is becoming possible. This paper presents a study of a cross-media annotation technology. In this technology, some multimedia examples expressed by structured information segments are submitted to a cross-media meta-search engine, to which the results in return, as the examples of other multimedia, are submitted again. The correlation between those examples and results is calculated per-time so that a cross-media semantic network is constructed by the iterative process. Thus the content of a Web page could be explained by different audio-visual perceptive cross-media information using the semantic network. This technology is proved to be feasible and effectual in the archetype system CMA (Cross Media Annotation). View full abstract»

    Gap analysis is one of the most important phases in implementation of enterprise resource planning (ERP) system. In this paper, an approach is proposed to automatically detect gaps between software capacities and organizational needs based on semantic similarity computation. The approach takes two business process models as input, and one specifies software capacities and the other describes organizational needs. The output of it is a report of gaps. As a matter of fact, the differences between application domain and software discipline make semantic heterogeneity a key problem in gap detection, therefore the technologies of semantic similarity computing are employed to resolve ambiguity issues caused by the use of synonyms or homonyms. In particular, the idea of similarity propagation is introduced to pick out a mapping between corresponding activities and data, and Hungarian algorithm is employed to reduce its time complexity. Then the similarity of whole models is measured according to the minimal total cost of change operations. Finally, an experiment is given to evaluate the method. View full abstract»

    This paper analyzes the feasibility of agent application in the network centric Warfare (NCW), and points out the difficulties in this process as well. The Semantic Web-based information processing framework is constructed, so that we can process information based on agent, effectively translate information superiority into knowledge superiority and finally build the decision superiority. At the same time, this paper also propose an ontology-based Web Service description model to describe the Web Services in multi-directions, on the basis of which agent can accurately and correctly comprehend the function and process of Web Services. Thus, a general platform-independent technological framework is built to make agent automatically invoke and compose the Web Services, and the interconnection, intercommunication and interoperation of information on various platforms also can be realized finally.

    In generalization refactoring, preconditions and allowable source code modifications depend on type constraints of the refactored program. Type constraints of parameterized types should be considered when applying the refactoring to generic programs, otherwise type errors may be brought into the refactored program. Some type constraint rules for Java generic programs are presented to verify the preconditions in the refactoring. The type constraints can be solved by traversing a type constraint graph. Based on the type constraint graph, a refactoring algorithm for extract interface is proposed. View full abstract»

    P2P networks have become a popular way to share large volumes of data due to its open and anonymous nature. P2P network model is designed with the targets of decentralization, well-scaling, fault-tolerance and low cost. Meanwhile however, new targets bring new challenges. P2P network expose more security threats due to its open and anonymous nature. P2P networks are vulnerable to attacks by malicious peers that have an incentive to spread viruses, in authentic data, or provide poor quality services. In this paper, we analyze the potential trust problems for different kinds of P2P networks, and then present the general trust factors that are indispensable for building trust models in any kinds of networks.

    In the Web personalization of Web service and construction of adaptive Web site, how to represent uses profile is one of the key issues. Aiming at solving the existing problems in representation of user profile includes incapability of effectively representing userpsilas recent interest, lack in dynamically effectively updating. This paper presents a new method of representation of user profile. By computing the interest degree with association degree between topics, updating of interest degree is preformed. By introducing memory model, it can predict which Web pages are still concerned by the user. By classifying the operations on the presented user profile, the construction and evolution can be done. In case study a userpsilas browsing activities is traced and corresponding user profile is built and evolves, thus to prove the feasibility of this method. View full abstract»

    As our dependence on online services has steadily grown, the development of Web applications is becoming crucial to commercial success of organizations. However, adjusting business vision to new market conditions leads to high volatility in requirements of Web applications. Thus, the organizations require Web systems to update and/or grow at a rate of business requirements change. To address the issue, we propose a MDA-based approach to workflow-oriented Web application development. It focuses on modeling and analysis of business requirements in CIM level and model transformation from business process to BPEL in PIM level through a well-defined mapping. To assist the developers, we also provide a support tool suite for practical Web projects. View full abstract»

    Ant Colony Algorithm and Genetic Algorithm (GA), two bionic-inspired optimization algorithms, have great potentials to solve the combination optimization problems, respectively used in solving traveling salesman problem, but there are some shortcomings if only one of them is used to solve TSP. Performance comparative analysis have been done by using ACA and GA respectively in solving TSP in this paper. The experiments show the advantages and disadvantages used only ACA or GA, we can overcome the shortcomings if GA and ACA are combined to solve TSP and get faster convergent speed and more accurate results compared with only using ACA or GA.

    The implement of machine translation system based on semantic element (SE) requires a large scale semantic element base. An automatic acquisition method for SEs based on statistical decomposition was proposed in this paper. Firstly, .analogical decomposition was applied to decompose abandonable SE and two conditions are found to assure the correctness of decomposition. Secondly, three statistics were designed, namely parameter index, translation index and language model index, to measure the rationality of analogical decomposition. Finally, multi-attribute decision making values for the above three statistics were prioritized to choose the best decomposition. Abandonable SE could be decomposed iteratively thereafter. Experimental results show that the accuracy has reached around 60%. View full abstract»

    Web service becomes an important paradigm for internet application. To realize userspsila complex requirements, services with different functions, but sharing common features, should be selected quickly from a huge number of services on internet to be collaborated. Researches on the discovery of services have put the emphasis on the finding out of services with similar functions, which is unable to accomplish the purpose of collaboration. We propose a discovery method for the collaboration based on Collaborated Semantic Link Network. C-SLN is constructed using services represented by E-FCMs and the similar and associated relations between E-FCMs as well. Through the experiments on a set of public web services, our approach shows that it can help to improve the efficiency of the discovery of services in favor of the collaboration. View full abstract»

    Semantic Web service matchmaking is the process of searching the space of possible matches between demands and supplies, and finds the best available ones. To achieve this, the semantic Web service matchmaking framework is one of the absolutely necessary components of service oriented architecture. This paper proposes a matchmaking framework based on Description Logic for semantic Web service described by RDF4S model, a novel semantic Web service description which consists of three layers: service oriented knowledge base, semantic description model and semantic description language. We describe the service description and service query conditions by using the ontologies that are included in service oriented knowledge base. The service resource specification is described according to Description Logics syntax and a Description Logic reasoner is used to compare service descriptions. By representing the semantics of service descriptions, the matchmaker enables the behavior of an intelligent agent to approach more closely that of a human user trying to locate suitable Web service resources.
