Concept Extraction Applied to the Task of Expert Finding [chapter]

Georgeta Bordea
2010 Lecture Notes in Computer Science  
The Semantic Web uses formal ontologies as a key instrument in order to add structure to the data, but building domain specific ontologies is still a difficult, time consuming and error-prone process since  ...  Therefore the development of fast and cheap solutions for ontology learning from text is a key factor for the success and large scale adoption of the Semantic Web.  ...  We wish to thank Paul Buitelaar for his valuable contributions and supervision.  ...

Moveek: a semantic social network

Pablo Camarillo Ramírez, Abraham Sánchez L., David Núñez R.
2012 Research in Computing Science  
We must therefore devise means for transforming existing, non-semantic social networks into semantic social networks. We propose using information extraction ontologies to handle this challenge.  ...  In this work we show how a successful ontology-based data-extraction technique can automatically generate semantic annotations for social networks.  ...  For discovering the knowledge, our proposal is completed when we use all Web services mentioned previously. Every Web service has a key role in our architecture.  ...

In this paper, we present a framework that can process user query for retrieval of information from documents of different properties across multiple domains, with specific application to patent laws and  ...  A case example is given to demonstrate how results from multiple domain searches can be combined using ontology and cross referencing. A user feedback mechanism is also discussed in this paper.  ...  Extracting Features on Publications To determine if a scientific publication is important or relevant to a patent, we need to extract certain features and quantify them.  ...

Unstructured information organization based on ontology

Zhigang Ji, Gang Liu, Qingyu Sun
2010 2010 International Conference on E-Health Networking Digital Ecosystems and Technologies (EDT)  
In this context, we propose a new approach of ontology based information correlation from various web resources.  ...  Therefore, the (semi-)automatic applications become necessity to find appropriate information in a brief time.  ...  These concepts constitute the key of extraction process, and consequently extracted information will populate the system ontologies.  ...

An Ontology-based Architecture for Cooperative Information Agents

Frederico Luiz Gonçalves de Freitas, Guilherme Bittencourt
2003 International Joint Conference on Artificial Intelligence  
To enable cooperation, two design requirements are crucial: (a) a Web vision coupling a vision for contents (classes and attributes to be extracted) to a functional vision (the role of pages in information  ...  Employing this Web vision and agents' cooperation can accelerate the retrieval of useful pages. We got encouraging results with two agents for the page classes of scientific events and articles.  ...  A key requirement for CIG systems came up with the tests: a detailed ontology is needed to process the richness of a cluster's domain.  ...
