Capturing Multi-Perspective Knowledge of Job Activities for Training

Dimoklis Despotakis
2010 European Conference on Technology Enhanced Learning  
The proposed approach aims at extracting an advanced context model which will augment digital records of job activities with semantics, and will provide intelligent search to augment simulated context  ...  The main limitations are the poor structure and the lack of approaches to retrieve the knowledge nuggets embedded in the existing digital content (e.g. videos or user stories) and to relate them to the  ...  On the other hand, there is a remarkable amount of resources available over the web, which offer rich content related to job activities and every day practice that can be used as a source for capturing  ...

Automated Concept Discovery from Web Resources

Michael Dittenbach, Helmut Berger, Dieter Merkl
2006 2006 IEEE/WIC/ACM International Conference on Web Intelligence (WI 2006 Main Conference Proceedings)(WI'06)  
The result materializes as a network of semantic concepts with their various contextual interrelations and provides a holistic view on the topic of interest.  ...  The task of researching information on a particular topic using the Web is mainly accomplished by using keywordbased search engines.  ...  To bring the Semantic Web to life, however, efficient ways to access and extract semantic concepts from Web documents are needed.  ...

Searching for Flash Movies on the Web: A Content and Context Based Framework

Jun Yang, Qing Li, Liu Wenyin, Yueting Zhuang
2005 World wide web (Bussum)  
The phenomenal growth of online Flash movies in recent years has made Flash one of the most prevalent media formats on the Web.  ...  The retrieval and management issues of Flash, vital to the utilization of the enormous Flash resource, are unfortunately overlooked by the research community.  ...  The contextual text of a movie refers to the textual parts of a web page that are most descriptive to the meaning of the embedded movies.  ...

An approach for service oriented discovery and retrieval of spatial data

Manoj Paul, S. K. Ghosh
2006 Proceedings of the 2006 international workshop on Service-oriented software engineering - SOSE '06  
The implementation is in compliant with the Web Map Service (WMS) and Web Feature Service (WFS), the web service standards proposed by OGC.  ...  Ontology-based discovery and retrieval of geographic data solves the problem of semantic heterogeneity, the major bottleneck for spatial interoperability.  ...  As a consequence, the system must contain a module that uses the resource descriptions in the ontology in order to translate a user query into sub queries that refers directly to the schemas of the data  ...
