[Draft] Management of Conversation-Oriented Languages for Semantic Web Services through Marked Petri Nets

This draft paper is written as part of a master course in Semantic Web, collecting key issues around composition of semantic web services, from the point of view of the representation of formal execution semantics and conceptual models based on marked Petri nets.

Special thanks to José Emilio Labra Gayo, and Juan Miguel Gómez Berbis for their support.

Abstract

This paper reviews the needs of a collaborative web environment to model visual interactive marked Petri nets, focusing on the issues around the definition of semantic web services interaction languages and modeling of instance conversations derived from them. So that, we start describing the traditional requirements for those languages and discussing the background of graph visualization and interaction concerns. Once reviewed all key issues among those broad areas we present our suggested approach, describing briefly a proof of concept prototype and introducing our future work around graph structured semantic information related with conversation-oriented languages for semantic web services composition and mediation.

[Draft] Visualization, Navigation and Edition of Graph Structured Semantic Information

This draft paper is written as part of a master course in Semantic Web, collecting key issues around graph visualization and interaction, from the point of view of the representation of semantic information based on RDF and OWL.

Special thanks to José Emilio Labra Gayo for such great references, like the graph survey by Herman et al. and the article by M.C. Schraefel and A. Karger.

Abstract

This paper focuses on the concepts related to the visualization, navigation and edition of semantic data which can be represented in graph structured formats, widely used in the Semantic Web; like RDF and other extensions as RDFS or OWL. First of all, a background introduction presents concepts like size, planarity, predictability and time complexity related to graph visualization. Later on we offer an overview of available layout algorithms and interaction key issues. And finally, we describe briefly a proof of concept prototype and introduce our future work around graph structured semantic information tools.

IADIS Interfaces and Human Computer Interaction Conference 2008 (IHCI)

I have just received the acceptance of the paper:
Web Environment for Collaborative and Extensible Diagram Design

Paper is proposed to be in the proceedings of IADIS Interfaces and Human Computer Interaction Conference 2008 (IHCI) as "Reflection Paper" . However, I had to renounce to publish it due to personal issues, economical mayorly. I also think that it can be improved a lot, as can be realized reading reviewers comments.

Somme positive comments for the paper are:

• "The paper has reasonable technical quality, and clear and consistent diagram and use of technical language"
• "The architecture is based on newly technologies and use well-known patterns"
• "The subject is relevant: Collaborative web-based tools demand a lot of research and implementation work"
• "An excellent idea, very promissing but a lack of credibility as regard to the implementation and the evaluation"
• "Very interesting key issue"

Also, some weak points were remarked by reviewers:

• "This is more a position paper than the result of implementatory work"
• "The lack of any sort of formal discussion or results, makes it hard to see the real world value of the model proposed"
• "Scenarios could be used to improve the explanation, even using hypothetical situations/applications"
• "There is not a proof of concept"
• "In addition, the introduction needs to be expanded to include an overview of the literature on collaborative web-based systems and how is the main differences/similarities with respect to other existing tools (e.g. Google docs)"
• "Unfortunately, there is no evaluation that measures the impact of the system on actual users"
• "It seems unusual to have a paper written in English with references written in any other language"
• "You claim as key words psychology and data mining but you don't adress these questions seriously"
• "Your bibliography could be broadenned"
