    Some exciting things have been happening on the Web. One of them you're probably already familiar with: the so-called "Web 2.0" revolution with the growth of blogging, wikis, tagging spaces and social networking. However, somewhat in the background another set of technologies, has been growing, and even the Web 2.0 crowd is starting to take notice. In the past year, a number of startups have been ...

    The fundamental information unit in the current Web, the WWW, is a node which currently is a document (or a page) that is connected to other nodes using manually created referential links. By creating infrastructure for processing, storage, communication, organization, search, and presentation of all information available on this Web, the most accessible and ubiquitous source of knowledge and comm...

    The Web 2.0, GRID applications and, more recently, semantic desktop applications are bringing the Web to a situation where more and more data and metadata are shared and made available to large user groups. In this context, metadata may be tags or complex graph structures such as file system or web directories, or (lightweight) ontologies. In turn, users can themselves be tagged by certain propert...

    Ontology construction itself is a big challenge, especially when the ontology is expected to have relevance and value to a broad audience. In recent years, many collaborative methods for ontology construction are proposed. However, whenever there is collaborative developments there are conflicts. Current collaborative methods are suitable for teamwork, but they are ineffective if the team is big a... View full abstract»

    Ontology mapping seeks to find semantic correspondences between similar elements of different ontologies. Ontology mapping is critical to achieve semantic interoperability in the WWW. To solve the ontology mapping problem, this paper proposes a non-instance learning-based approach that transforms the ontology mapping problem to a binary classification problem and utilizes machine learning techniqu...

    In this paper, we put forward the method to design and implementation of vegetable supply chain knowledge acquisition system. First, a formalized vegetable supply chain ontology model by RDF is constructed; and then a two layers semantic reasoning model is set up; finally, the vegetable supply chain knowledge acquisition system based on ontology is realized, which is with high recall and precision...

  • An Ontology Model for Execution Records of Grid Scientific Applications

    Publication Year: 2008, Page(s):34 - 41
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (273 KB) | HTML iconHTML

    Records of past application executions are particularly important in the case of loosely-coupled, workflow driven scientific applications which are used to conduct in silico experiments, often on top of Grid infrastructures. In this paper, we propose an ontology-based model for storing and querying over the execution records of Grid scientific applications. The model comprises various aspects of t... View full abstract»

    OWL and RDF/RDFS are ontological languages developed by the World Wide Web Consortium (W3C), which have become a de facto standard for the ontological descriptions in various domains. The evolution of these standards was influenced by the numerous advances in the research of knowledge representation and reasoning. Although support for reasoning and standardized representation is the key benefit of... View full abstract»

    Ontology is a technology for conceptualizing specific domain knowledge, which can provide machine-readable definitions to the severed domain. Therefore, ontology can be utilized to enhance the performance of focused crawlers, by precisely defining the crawling boundary. In this paper, we will exhibit a conceptual framework of an ontology-based focused crawler serving in the domain of transport ser... View full abstract»

    There is huge explosion in the number of new databases, applications and documents in the recent past. This results into lot of redundancy and duplication, which leads to high inefficiency in query processing. Most of the users, who need the information, are naive, because they do not have knowledge of internal structures of databases, contents of data sources and query languages. So it is very di...

    This paper presents a method for the interconnection of heterogeneous knowledge bases on a knowledge grid for knowledge sharing and provision. Various knowledge bases have been created by using collaborative editing environments such as Wiki in each field. Each knowledge base exists independently. On the other hand, an event affects various aspects of an area, field or community. Therefore, in tod... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (371 KB) | HTML iconHTML

    Due to diversity of data formats, missing of certain properties, imprecise records in heterogeneous literature databases, there exist duplicate records when integrating heterogeneous databases. Duplicate records lower the efficiency of information retrieval. In this paper, we propose an approach, named length filtering and dynamic weighting (LFDW) for duplicate records cleansing. There are three s... View full abstract»

    Mining frequent patterns from transaction-oriented database is an important problem. Frequent patterns are essential for generate association rules, time series, etc. Most of frequent patterns mining algorithm can be classified into two categories: generate-and-test approach (Apriori-like) and pattern growth approach (FP-tree). In recent times, many methods have been proposed for solving this prob... View full abstract»

    Independent grid projects have developed their own solutions to information services. These solutions are not interoperable with each other, target vastly different systems and address diverse sets of requirements. To address these challenges, we designed a novel architecture for a grid information service that provides unification, federation and interoperability of major grid information service...

    Associated knowledge flow (AKF) is a sequential link between associated topics, which can be applied to intelligent browsing and personalized recommendation. One key problem is how to measure the knowledge delivery quantity (KDQ) on an AKF. In this paper, a computational method of knowledge delivery quantity on an AKF is proposed. Firstly, considering the keywords and associated relations between ... View full abstract»
