E-travel is comprehensive framework for delivering personalized travel services using agent infrastructure based on our works in agent-related fields: Multimodal Communication Between Users and Software Agents and Modelling User on the Basis of Interactions with a WWW Based System. The system utilizes many existing up-to-day technologies related to the term of Semantic Web: JADE agent platform together with Jena semantic framework for processing ontology demarcated data. For easy and type safe access to ontology Jastor (Java beans generator from Web Ontologies (OWL)) has been used. Raccoon server provides a way to transform ontological data into browser-readable forms.
Our solution addresses set of the following problems:
* Connecting synchronous HTTP protocol with asynchronous nature of software agents.
* Web browser and mobile interface providing natural access to the multi-agent system.
* Separation of data and view thanks to: Model-View-Controller architecture, ontologies and Raccoon server for transforming data into view.
* Content personalization basen on user modelling, including: stereotyping, user profile learning and exploitation.
Semantics in Business Systems begins with a description of what semantics are and how they affect business systems. It examines four main aspects of the application of semantics to systems, specifically: How do we infer meaning from unstructured information, how do application systems make meaning as they operate, how do practitioners uncover meaning in business settings, and how do we understand and communicate what we have deduced? This book illustrates how this applies to the future of application system development, especially how it informs and affects Web services and business rule- based approaches, and how semantics will play out with XML and the semantic Web. The book also contains a quick reference guide to related terms and technologies. It is part of Morgan Kaufmann's series of Savvy Manager's Guides.
