DC Proposal: Decision Support Methods in Community-Driven Knowledge Curation Platforms [chapter]

Razan Paul
2011 Lecture Notes in Computer Science  
Semantic Web technologies can, however, provide the appropriate means for encoding the knowledge and hence enabling complex forms of reasoning.  ...  Performing efficient and automated knowledge discovery in this domain poses serious challenges, one of the main issues being the lack of a proper formalization.  ...  The work presented in this paper is supported by the Australian Research Council (ARC) under the Linkage grant SKELETOME -LP100100156.  ...

A collaborative decision framework for managing changes in e-Government services

Dimitris Apostolou, Gregoris Mentzas, Ljiljana Stojanovic, Barbara Thoenssen, Tomás Pariente Lobo
2011 Government Information Quarterly  
We argue that such a synthesis of systematic response to changes with knowledge to deal with them has a positive impact on the change management process.  ...  In this paper, we address this challenge by presenting an ontology-based approach that: (i) enables systematic response of e-Government systems to changes by applying formal methods for achieving consistency  ...  Acknowledgments We thank the European Commission for its funding and our partners in the OntoGov project for their contributions to the development of OntoGov.  ...

Social Networks Applied

S. Staab, P. Domingos, P. Mika, J. Golbeck, Li Ding, T. Finin, A. Joshi, A. Nowak, R.R. Vallacher
2005 IEEE Intelligent Systems  
We model how likely each customer is to buy some product, as a function of the customer's and product's intrinsic properties and of the influence of the customer's neighbors in the network.  ...  In the past, this was due largely to lack of data; the networks available for study were small and few and contained minimal information about each node.  ...  Acknowledgments The Vrije Universiteit Research School for Business Information Sciences (VUBIS) provided funding for this work.  ...

From science to e-Science to Semantic e-Science: A Heliophysics case study

Thomas Narock, Peter Fox
2012 Computers & Geosciences  
The integration of search with web services, relational databases, and other cyberinfrastructure is a central tenet of our case study and one that we believe has applicability as a generalized research  ...  The Semantic Web has proven invaluable in this effort; however, much of the literature is devoted to system design, ontology creation, and trials and tribulations of current technologies.  ...  Yet, our case study has shed light on emerging issues and provides empirical evidence in support of some of the founding tenets (Fox and Hendler, 2009a) of Semantic e-Science.  ...

Search on the Semantic Web

Li Ding, T. Finin, A. Joshi, Yun Peng, Rong Pan, P. Reddivari
2005 Computer  
For example, an agent reasoning over the content found in an SWD should access and process all of the ontologies it imports.  ...  Swoogle considers an SWD to be an ontology document (SWO) if its ontology ratio exceeds an empirical threshold (that is, 0.8); • Relational metadata.  ...

2008 Leadership Quarterly  
Thus, an alternative leadership ontology is proposed: direction, alignment, and commitment. A theoretical framework based on such an ontology is sketched out.  ...  The further development of leadership theory calls for a corresponding development at the level of leadership ontology.  ...  Acknowledgements The authors would like to thank David Day, Fred Morgeson, Anson Seers, Mary Uhl-Bien, and Gary Yukl for their very helpful comments on an earlier draft of this paper.  ...

A Comparative Study of Ontology Languages and Tools [chapter]

Xiaomeng Su, Lars Ilebrekke
2002 Lecture Notes in Computer Science  
Ontology attracts many attentions nowadays in computer science, largely because of the envision of semantic web, where real "semantic" of the web lies in ontology.  ...  There are many languages and tools for constructing ontologies. In this paper we survey and compare different ontology languages and tools by the aid of an evaluation framework.  ...  We adopt one of the definitions from Uscholod [33] : "ontology is an explicit representation of a conceptualization.  ...
