Open semantic service networks
Online service marketplaces will soon be part of the economy to scale the provision of specialized multi-party services through automation and standardization. Current research, such as the *-USDL service description language family, is already deļ¬ning the basic building blocks to model the next generation of business services. Nonetheless, the developments being made do not target to interconnect services via service relationships. Without the concept of relationship, marketplaces will be seen as mere functional silos containing service descriptions. Yet, in real economies, all services are related and connected. Therefore, to address this gap we introduce the concept of open semantic service network (OSSN), concerned with the establishment of rich relationships between services. These networks will provide valuable knowledge on the global service economy, which can be exploited for many socio-economic and scientiļ¬c purposes such as service network analysis, management, and control
Product information management for complex modular security systems
Um sistema PIM gere toda a informaĆ§Ć£o que possibilita a comercializaĆ§Ć£o dos produtos
atravĆ©s de diferentes canais. A sua importĆ¢ncia durante o ciclo de vida de um produto
aumentou devido Ć sofisticaĆ§Ć£o tĆ©cnica dos produtos, a gerir internamente e a publicar
externamente. Sistemas, tais como o ERP e o CCMS, deverĆ£o integrar-se com um sistema
PIM, o qual deve funcionar como a āespinha dorsalā da informaĆ§Ć£o de produto.
O presente projeto tem como objetivo principal a criaĆ§Ć£o de uma soluĆ§Ć£o para gerir a
informaĆ§Ć£o de produto para sistemas modulares complexos. A proposta de soluĆ§Ć£o inclui
a criaĆ§Ć£o de uma ontologia para parte dos inĆŗmeros sistemas disponĆveis no catĆ”logo de
produtos de uma das maiores organizaƧƵes multinacionais do setor de engenharia e
tecnologia a nĆvel mundial. O processo de criaĆ§Ć£o da soluĆ§Ć£o proposta baseou-se na
metodologia de investigaĆ§Ć£o pesquisa-aĆ§Ć£o e foi dividido em cinco fases. Na fase de
diagnĆ³stico descreveu-se e analisou-se a atual situaĆ§Ć£o dos sistemas ERP e CCMS que
gerem o catƔlogo online dos sistemas de produtos comercializados. Levantaram-se ainda
as taxonomias de produto atuais e elaborou-se a proposta. Na fase de planeamento da
aĆ§Ć£o descreveram-se a equipa de trabalho, a abordagem inspirada na metodologia Agile
usada para desenvolver a soluĆ§Ć£o, as reuniƵes de planeamento, os parceiros de trabalho,
as ferramentas a usar e a sua justificaĆ§Ć£o. Na fase de tomada de aĆ§Ć£o foi descrito o
processo de criaĆ§Ć£o da soluĆ§Ć£o ontolĆ³gica e o resultado final, incluindo a construĆ§Ć£o das
novas taxonomias e a sua validaĆ§Ć£o pelos especialistas. Propuseram-se exemplos e
representaƧƵes grĆ”ficas usando a ferramenta ProtĆ©gĆ©. Na fase de avaliaĆ§Ć£o, a soluĆ§Ć£o
ontolĆ³gica foi testada, tendo-se validado que os requisitos necessĆ”rios foram satisfeitos
pela estrutura. Na fase de especificaĆ§Ć£o de aprendizagem propuseram-se os prĆ³ximos
passos para a implementaĆ§Ć£o e gestĆ£o futura do modelo ontolĆ³gico.
Com esta soluĆ§Ć£o, a organizaĆ§Ć£o poderĆ” gerir mais eficientemente a informaĆ§Ć£o de
produto e a estrutura de dados. Ela possui versatilidade para gerir produtos individuais ou
sistemas modulares complexos e melhorar a sua comunicaĆ§Ć£o com o cliente. AlĆ©m disso,
a ontologia tem ainda um enorme potencial se combinada com tƩcnicas de IA. Algumas
limitaƧƵes do projeto e propostas de trabalhos futuros foram ainda apresentadas
CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap
After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in
multimedia search engines, we have identified and analyzed gaps within European research effort during our second year.
In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio-
economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown
of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on
requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the
community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our
Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as
National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core
technological gaps that involve research challenges, and āenablersā, which are not necessarily technical research
challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal
challenges
Combination of web usage, content and structure information for diverse web mining applications in the tourism context and the context of users with disabilities
188 p.This PhD focuses on the application of machine learning techniques for behaviourmodelling in different types of websites. Using data mining techniques two aspects whichare problematic and difficult to solve have been addressed: getting the system todynamically adapt to possible changes of user preferences, and to try to extract theinformation necessary to ensure the adaptation in a transparent manner for the users,without infringing on their privacy. The work in question combines information of differentnature such as usage information, content information and website structure and usesappropriate web mining techniques to extract as much knowledge as possible from thewebsites. The extracted knowledge is used for different purposes such as adaptingwebsites to the users through proposals of interesting links, so that the users can get therelevant information more easily and comfortably; for discovering interests or needs ofusers accessing the website and to inform the service providers about it; or detectingproblems during navigation.Systems have been successfully generated for two completely different fields: thefield of tourism, working with the website of bidasoa turismo (www.bidasoaturismo.com)and, the field of disabled people, working with discapnet website (www.discapnet.com)from ONCE/Tecnosite foundation
