Pervasive environments are composed as spontaneous aggregation of heterogeneous and independent devices, which may seamlessly consume, but also provide, software resources over the network. As result, applications emerge from the dynamic composition of the resources available within the environment. This requires applications of being semantic-aware, to reason about and learn from the environment...
Modeling co-authorship networks merely in FOAF, as is common with social networks, suffers the inability to capture semantics which are specific to collaboration schemes in the scientific community. For instance, the weight of the co-author relation which expresses the magnitude of that relation between two co-authors is subject to change dynamically as new publications are assigned to the co-authorship...
In this paper we present a framework that extracts meaningful knowledge from microposts shared in social platforms in order to build user profiles. This process involves different steps for the analysis of such microposts (extraction of keywords, named entities and their matching to ontological concepts) and their weighting. The concept weighting involves different scores, such as sentiment analysis...
To address important marine research and application challenges, there is a critical need for ocean observatories to share data in a way that is easy to use and integrate. Fulfilling this interoperability requirement is greatly facilitated by several standards efforts and recent advancements in Web technology. Although these infrastructures provide a fundamental capability for data sharing, there...
