Semantic similarity and relatedness measures assess how alike two words are within a language and are playing an important role in the development of the Semantic Web. This thesis research advances the knowledge of existing similarity and relatedness measures. A generalized tool to experiment with semantic similarity and relatedness measures in a variety of ontological terminologies has been developed using the Simple Knowledge Organization System (SKOS), a proposed W3C standard for the Semantic Web. SKOS represents a terminology or domain vocabulary in a machine-understandable way. A flexible conversion tool is used to convert any vocabulary in the Unified Medical Language System (UMLS) Metathesaurus and OWL ontologies into an extended SKOS ontological terminology. The generalized tool for measuring semantic similarity and relatedness is then used to analyze a wide variety of semantic similarity measures and new set-based relatedness measures on three major vocabularies of the UMLS

Abstract—Recently, P2P lending has become a hot research topic in finance, especially after the global financial crisis. Most existing research did not consider the efficiency from the borrowers ’ perspective. This paper proposes a decision support system based on intelligent agents in P2P Lending for borrowers. The system provides borrowers with individual risk assessment, eligible lender search, lending combination and loan recommendation. The system is developed in JADE and evaluated with the PROSPER’s sample data. The result shows that, the model can meet borrower’s needs better and help borrower getting loan more efficiently. Furthermore, it contributes to finance industry by accelerating the funds flow and does favor to economic recovery. Index Terms—online P2P lending, loan recommendation, decision support system, intelligent agent system I.

There has been an emergence of various ontologies describing data from either the clinical or biological domains. Associated with this are attempts to develop systems that integrate clinical and biological ontologies using various strategies to overcome issues of scope, differing levels of granularity and conflicting user needs. However, lack of knowledge about user needs for such integration systems, and absence of a general framework to assess their suitability for specific application remain obstacles to their reuse and wide adoption in distributed computing environments. This paper describes a study that aims to address this problem by proposing an evaluation framework for ontology integration to suit user needs. The framework draws on existing ontology evaluation approaches in relating user objectives to ontology characteristics. Systems theory is used to explain the dynamics of a biomedical environment. The framework therefore includes feedbacks from the evaluation process to the user characteristics of the integrated systems. This framework was validated by a study using structured interviews and questionnaires in a survey. The results indicate that it is sufficiently flexible for evaluating ontology based biomedical integrated systems, taking into account the conflicting needs of different users interested in

A survey has been presented on the usage of ontology in various domains like Medical, Agriculture, Geosciences, Education, Marine, Communication, Computer, Chemical, Defence, Linguistic etc. A summary of the available ontology developed in various domains is given and no attempt has been made to evaluate them. Only a broad picture of ontology applications in various domains practiced today are described. In some cases details like number of concepts, relationship, classes and subclasses defined are also given. The survey indicated that considerable effort has gone in the development of ontology in the domains of medical, education, computer science. It is noted that rather limited effort has gone into the development of ontology in the domains of power plants and atomic energy.

Innovation within established industry can be viewed as a cyclic loop consisting of four distinct phases, i.e., recognition, initiation, implementation, and stabilization. Different information technology enabled innovation management tools supporting the lifecycle of innovation are classified as five layers, i.e., individual innovation, project innovation, collaborative innovation, distributed innovation, and semantic innovation. According the fact that the current state is evolving from distributed innovation to semantic innovation, this paper focus on the realization of Semantic Web technologies enabled semantic innovation. To explicitly and formally specify all the different perspectives of innovation related information, a shared ontology is proposed as the common language of innovation management, which describes the critical and minimal information about the innovation process in a holistic way. Then, a technical framework which employs the machine readable innovation ontology to actually improve innovation management inside an organization and among loosely coupled organizations is presented. Finally, some features of the semantic innovation are discussed.

Abstract. Current efforts in Semantic Web Services lack reusability and often lack a clear separation between Web services and user goals. We propose a unified architecture based on the principles of the Web Services Modeling Framework WSMF together with the Unified Problem-Solving Method Development Language UPML in order to make the vision of reusable Semantic Web Services a reality. We reuse the concept of a task- and domain-independent Problem-Solving-Method to introduce goal- and domain-independent Web services, organized in Web Service Libraries. Reuse is achieved through the use of bridges and refiners for goal, Web service and domain descriptions. A conceptual agent architecture combines these descriptions in order to achieve user goals with reusable Semantic Web Services.
Coevolution of Database Schemas and Associated Ontologies in Biological Context
