The key problem in data integration systems is creating and maintaining mappings between schemas of heterogeneously structured data sources. The problem becomes increasingly important in P2P environment when new partners enter the system and their schemas evolve. In this work we focus on deriving mappings between XML schemas using their annotations in common domain ontology. A special attention is...
Semantic Business Process Management is a recent and promising research area devoted to extending the results from Semantic Web Services - i.e., the application of ontology-based modelling and reasoning to Web Services - to Business Process Management, which is these days often realised using Service-Oriented Architectures. One important task for Semantic Business Process Management is the addition...
In a previous work we presented an approach to allow invocation of services whose interface and behavior differ from each other. Such approach requires the definition of scripts by some human being able to completely understand the mismatches and properly combine the mapping functions. Furthermore, such approach requires an intensive effort from a system integrator that, in the worst case in which...
Configuration management is a key issue in flexible networking experimentation infrastructures (i.e., testbeds). However, manual procedures have several drawbacks (such as high time consumption in tedious and mechanic operations or the probability of introducing human errors). Moreover, inter-testbed scenario reutilization (i.e., the same network configuration replicated from one testbed to another)...
The identification of new useful patterns in data is a core process for intelligent systems. Information overflow is directly related to this problem. In this work we propose a knowledge discovery methodology to retrieve useful and novel information from raw data stored in a DBMS. We used ALSDB, a database that has been built suitably to access structured information obtained from the questionnaires...
FMEA (Failure Modes and Effects Analysis) is a method to analyze potential reliability problems in the development cycle of the project, making it easier to take actions to overcome such issues, thus enhancing the reliability through design. FMEA is used to identify actions to mitigate the analyzed potential failure modes and their effect on the operations. Anticipating these failure modes, being...
The Universal Business Language (UBL) is an initiative to develop common business document schemas for interoperability. However, businesses operate in different industry, geopolitical, and regulatory contexts and have different rules and requirements for the information they exchange. So, several trading communities are tailoring UBL schemas to their needs, requiring that these schemas translate...
Ontology (RDF/OWL) plays a foundational role of semantic Web for knowledge representation. But nowadays there are few Chinese ontology bases available, which hinders the research and development of Chinese Semantic Web applications. This paper introduces an ontology knowledge discovery tool, named OntoLTCn, which supports semi-auto domain ontology acquisition from Chinese corpus. In brief, OntoLTCn...
Domain specific ontologies can be used to improve both precision and recall of information retrieval systems. One approach in this regard is using query expansion techniques and the other would be introducing a semantic similarity measure for concepts in ontology. Although each approach has its own benefits and drawbacks, query expansion techniques are preferred when the corpus volume is so huge that...
Existing knowledge based grid workflow languages and composition tools require sophisticated expertise of domain scientists in order to automate the process of managing workflows and its components (activities). So far semantic workflow specification and management has not been addressed from a general and integrated perspective. This paper presents a novel domain oriented approach which features...
Digital repositories can preserve terabytes of information in the form of digital documents. Searching these digital documents requires time and computing resources. Techniques are required to efficiently process these digital repositories. Metadata and semantic annotations can augment the overall search process and provide a foundation to build intelligent applications by using the documents in the...
Integrating service description, discovery, and invocation functionalities presents several fundamental problems in the management of web services and is a basic problem for composing Web services over a network. In this paper, we present the design of a system called "semantic service, wrapper, and invocation manager" (SSWiM) which provides these key functionalities. In particular, SSWiM...
