TRUST CALCULATION Semantic Agreement for Ontology Integration
نویسندگان
چکیده
The Semantic Web is generally envisioned as a vast collection of document embedded knowledge that makes it highly improbable for agents traversing this space to know directly what entity, person, or organisation they are dealing with. In such an environment, the explicit representation of trust becomes an intrinsic part of calculating whether an agent can believe and use (or reuse) foreign sources. A key activity in this process is the step of integrating an agent’s ontology with that of another document found on the Web. To assist in calculating trust values for this purpose, Riposte provides a set of trust models and trust manipulation algorithms to create a dynamic model of author trust based on work that is being provided to an agent. Riposte is an ontology integration tool that uses suggestions and bases trust on whether an object in the provided ontology confirms or refutes current beliefs. The author can be assigned an initial trust value and this value is recalculated after the integration process.

Trust Based Ontology Integration For The Community Services Sector
As ontologies become more prevalent for information management the need to manage the ontologies increases. In the community services sector multiple organisations often combine to tender for funding. When separate organisations come together to generate reports for funding bodies an alignment of terminology and semantics is required. Ontology creation is privatised for these individual organis...
متن کاملCentralized Clustering Method To Increase Accuracy In Ontology Matching Systems
Ontology is the main infrastructure of the Semantic Web which provides facilities for integration, searching and sharing of information on the web. Development of ontologies as the basis of semantic web and their heterogeneities have led to the existence of ontology matching. By emerging large-scale ontologies in real domain, the ontology matching systems faced with some problem like memory con...
متن کاملLet's talk about our "being": A linguistic-based ontology framework for coordinating agents
In open scenarios, agents willing to cooperate must impact the communication barrier between them and their unknown partners. If agents are not relying on any agreement about the meaning they ascribe to the symbols used in the conversation, semantic misalignments will arise on the discourse domain as well, thus making the communication impossible. In wide and heterogeneous scenarios offered by ...
متن کاملAn Improved Semantic Schema Matching Approach
Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...
متن کاملPublic Transport Ontology for Passenger Information Retrieval
Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...
