Towards Browsing Distant Metadata Using Semantic Signatures
نویسندگان
چکیده
In this document, we describe a light-weighted ontology mediation method that allows users to send semantic queries to distant data repositories to browse for learning object metadata. In a collaborative E-learning community, member data repositories might use different ontologies to control a set of vocabularies describing topics in learning resources. This could hinder the search of learning resources based on local ontological concepts. With the use of WordNet, we develop a toolkit that indexes ontological concepts with WordNet senses for semantic browsing in order to integrate information in a distributed learning community. The effectiveness of the toolkit was validated with real-world data in a specific domain, namely Elearning metadata.

SemWeB: A Semantic Web Browser for Supporting the Browsing of Users Using Semantic and Adaptive Links
Web browsing is a complex activity and in general, users are not guided during browsing. The aim of this research is to support the browsing of users using semantic and adaptive hyperlinks using Semantic Web technologies and personalization methods. In this paper, we propose a novel Semantic Web browser (SemWeB), which uses a behavior-based and an ontology-driven user modeling architecture. In ...
متن کاملSemantically Linking and Browsing Provenance Logs for E-science
e-Science experiments are those performed using computerbased resources such as database searches, simulations or other applications. Like their laboratory based counterparts, the data associated with an e-Science experiment are of reduced value if other scientists are not able to identify the origin, or provenance, of those data. Provenance is the term given to metadata about experiment proces...
متن کاملEfficient Content Creation on the Semantic Web Using Metadata Schemas with Domain Ontology Services (System Description)
Metadata creation is one of the major challenges in developing the Semantic Web. This paper discusses how to make provision of metadata easier and costeffective by an annotation editor combined with shared ontology services. We have developed an annotation system supporting distributed collaboration in creating annotations, and hiding the complexity of the annotation schema and the domain ontol...

The realization of Semantic Web vision is based on the creation and use of semantic web content which needs software tools both for semantic web developers and end users. Over the past few years, semantic web software tools like ontology editors and triple storage systems have emerged and are growing in maturity with time. While working on a large triple dataset during the course of a research ...
متن کاملEfficient Web Browsing with Semantic Annotation: A Case Study of Product Images in E-Commerce Sites
Web browsing task is based on depth-first searching scheme, so that searching relevant information from Web may be very tedious. In this paper, we propose personal browsing assistant system based on user intentions modeling. Before explicitly requested by a user, this system can analyze the prefetched resources from the hyperlinked Webpages and compare them with the estimated user intention, so...
