Semantic Halo for Collaboration Tagging Systems
نویسندگان
چکیده
Collaborative tagging systems allow many users to add keywords (tags) to community-shared data items. Recently, collaborative tagging systems, also known as folksonomies, are growing on the web allowing people to annotate content, and then query by submitting keywords or tags. In this paper we define a Semantic Halo, as a set of additional information that can be provided from tagging systems to end users when retrieving user-relevant documents. We analyze the semantic aspects of tagging and provide an algorithm for computing the Semantic Halo of tags. Finally, we show some preliminary results that demonstrate the effectiveness of our approach.

Trail Patterns in Social Tagging Systems: Role of Tags as Digital Pheromones
The popularity of social information systems has been driven by their ability to help users manage, organize and share online resources. Though the research exploring the use of tags is relatively new, two things are widely acknowledged in the research community: (a) tags act as a medium for social collaboration, navigation and browsing and (b) an overall stable equilibrium exists among tag pat...
متن کاملAn Executive Approach Based On the Production of Fuzzy Ontology Using the Semantic Web Rule Language Method (SWRL)
Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...

متن کاملA New Method for Improving Computational Cost of Open Information Extraction Systems Using Log-Linear Model
Information extraction (IE) is a process of automatically providing a structured representation from an unstructured or semi-structured text. It is a long-standing challenge in natural language processing (NLP) which has been intensified by the increased volume of information and heterogeneity, and non-structured form of it. One of the core information extraction tasks is relation extraction wh...
