Therefore, we are also specifically interested in workshops which bridge the two conferences. Topics historically covered at our conference (such as semantics, LOD, social semantic web) will also be integrated into i-KNOW 2014 and contributions are encouraged to cover these topics. CONFERENCE THEME: Cognitive Computing and Data-Driven Business i-KNOW 2014 aims at advancing research at the intersection of disciplines such as knowledge discovery, semantics, information visualization, visual analytics, social (semantic) and ubiquitous computing. The goal of integrating these approaches is to create cognitive computing systems that will interact naturally with humans, learn from their experiences and generate and evaluate evidence-based hypotheses. That is, we interpret cognitive computing as the convergence of various knowledge technologies research fields. On the other hand, data-driven business represents the business perspective on cognitive computing and takes application specific knowledge (such as semantics) into account. We are specifically interested in the integration of data-centric and user-centric approaches and welcome contributions from both ends of the spectrum.
