Integrating Folksonomies with the Semantic Web
An approach for making explicit the semantics behind the tag space in social tagging systems, so that this collaborative organization can emerge in the form of groups of concepts and partial ontologies using a combination of shallow pre-processing strategies and statistical techniques. Expand
Semantic annotation for knowledge management: Requirements and a survey of the state of the art
This analysis shows that, while there is still some way to go before semantic annotation tools will be able to address fully all the knowledge management needs, research in the area is active and making good progress. Expand
Reusable components for knowledge modelling
An approach to the development of a library of problem solving components for knowledge modelling based on an epistemological modelling framework, the Task/Method/Domain/Application (TMDA) model, and on a principled methodology, which provides an integrated view of both library construction and application development by reuse.

AquaLog: An ontology-driven question answering system for organizational semantic intranets
AquaLog is a portable question-answering system which takes queries expressed in natural language and an ontology as input, and returns answers drawn from one or more knowledge bases (KBs) because the configuration time required to customize the system for a particular ontology is negligible. Expand
SemSearch: A Search Engine for the Semantic Web
SemSearch is presented, a search engine, which pays special attention to semantic search by providing several means to hide the complexity of semantic search from end users and thus make it easy to use and effective. Expand
PowerAqua: Supporting users in querying and exploring the Semantic Web
This work presents PowerAqua, an ontologybased Question Answering system that is able to answer queries by locating and integrating information, which can be distributed across heterogeneous semantic resources. Expand
IRS-II: A Framework and Infrastructure for Semantic Web Services
In this paper we describe IRS-II (Internet Reasoning Service) a framework and implemented infrastructure, whose main goal is to support the publication, location, composition and execution ofExpand
Watson, more than a Semantic Web search engine
An overview of the Watson system, a Semantic Web search engine providing various functionalities not only to find and locate ontologies and semantic data online, but also to explore the content of these semantic documents. Expand
An Overview of the OCML Modelling Language
This paper provides an overview of the OCML modelling language: it illustrates the underlying philosophy, describes the main modelling constructs provided, and compares it to other modellingExpand
MnM: Ontology Driven Semi-automatic and Automatic Support for Semantic Markup
M is presented, an annotation tool which provides both automated and semi-automated support for annotating web pages with semantic contents and integrates a web browser with an ontology editor and provides open APIs to link to ontology servers and for integrating information extraction tools. Expand
