Abstract
Corporate portals make an important integral part of the enterprise infrastructure, facilitating the creation, sharing, discovery and consumption of enterprise assets through blogs, news, forums, documents and information in general. However, as the amount of data grows, it becomes much more difficult to access the right asset in the precise moment when it is needed. Annotation systems tried to address this problem to a certain extent by allowing the users to collaboratively annotate assets using tags such that these assets can be found more easily by reusing these tags in queries. However, this model often falls short due to mismatches in the vocabularies of different users, due to the use of synonymous, polysemous, more specific or general terms in tagging and searching, and so on. In this paper we: (a) provide an analysis of the corporate portal of the Telefonica group; (b) identify requirements for a semantics-enabled annotation system that is capable of addressing the above-mentioned shortcomings; (c) define a semantic annotation model that meets the requirements; (d) provide the details of the implementation of the annotation model for the Telefonica portal; and (e) provide an initial evaluation from the use of the semantic annotation system in the enterprise.
