Semantic Annotators - how good are they, and how can we make them better?

Auditorio, Department of Computer Science, Universidad de Chile

This will be an informal talk discussing a line of research in Oxford on using semantic annotation services. The talk will overview what these services are, and discuss what we have discovered experimentally about their behavior. It will then go over some approaches we have developed for increasing the reliability of annotators, embedded in the ROSeAnn system for integrating and reconciling semantic annotations. This is joint work with Luying Chen, Giorgio Orsi, and Stefano Ortona, to be presented at VLDB’14.
