[Paper] Towards Meta-Model Interoperability of Models through Intelligent Transformation

I have just received the confirmation of a paper submitted to the International Symposium on Distributed Computing and Artificial Intelligence (DCAI'09), organized into the 10th International Work-Conference on Artificial Neural Networks (IWANN'09). This meeting will be held at the University of Salamanca in June 10-12th, 2009.

Special thanks to Vicente García Díaz, Oscar Sanjuán Martínez, Héctor Fernández Fernández and Gloria García Fernández for their support.

Abstract

Models and transformations between models are provided as the core of Model-Driven Engineering, offering reusability of knowledge and processes. In order to establish the basis of future advances in this emerging paradigm, this paper is focused on the principles of meta-models and transformation models. Moreover, the concept of meta-model is becoming an essential artifact for MDE based solutions, thus we have centered our background review in the state of art related with meta-model specifications and model transformation technologies. Our research is aimed at getting a higher degree of interoperability among available meta-model specifications by raising the transformation models to the upper meta-layers. Some conclusions extracted suggest that this is yet an early solution which demands greater efforts in terms of research, development and specification, with many interesting open subjects like design of generic editors for model-agnostic visual modeling, integration of models instances from different meta-models, improvements of the semantic knowledge offered by actual modeling languages or even the evaluation of the applicability of graph transformation techniques towards formal transformation models.

Full Paper

All papers accepted will be published in an special volume of IWANN in Lecture Notes in Computer Science (LNCS Springer Verlag). IWANN is included in the ranking of the best conferences established by the Computer Science Conference Ranking based on the "Estimated Impact of Conference (EIC)", concretely in position 55 among 620 considered (in the Artificial Intelligence field). Therefore the papers will be indexed by CiteSeer.IST, and by the organization Computing Research and Education Association (CORE).

A special issue in the International Journal of Artificial Intelligent Real-Time Automation (Engineering Applications of Artificial Intelligence), from Elsevier, will include a selection of between 10 to 15 papers published in DCAI 2009 (JCR 2007 - 0.762).

[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.
