Value proposition on a Web based knowledge Portal Joaquim Fernando Silva 1 Faculty of Engineering of University Of Oporto 1 joaquim.silva.pt , Abstract. Our focus is on value proposition as a concept of comprehending integration on a Web- based Knowledge Portal for educational purposes. In this early stage of our Portal framework design we bring some discussion of the usefulness in another web tool for learning. Introduction This study was carried out for a discipline, Integration of Information Systems, of the Doctoral Program in Informatics and tries to give some answers to these questions: What is the difference of this Web Portal in relation to others similar? What forms of knowledge construction are involved? Why accessing information from multiple information systems and integrating them into a knowledge portal are key issues? Some previous studies [1] took into account some technical aspects of building a Web-based Knowledge Portal for educational purposes, namely ontologies, concept maps and software agents to deal with semantic issues. Some aspects like syntactic and semantic interoperability were also considered. On this short paper first we present some considerations about value propositions as a new concept of integration. Next we characterise the learning platform we are working in and which value we will bring to make this a competitive advantage idea. Finally the conclusions of this essay are presented. The importance of value propositions According to [2] one must use a progressive approach for building information systems by aligning technology closer to business in a way that reflects the business need to adapt to market opportunities as governed by a strategic vision.
