There is an increasing amount of structure on the web as a result of modern web languages, user tagging and annotation, emerging robust NLP tools, and an ever growing volume of linked data. These meaningful, semantic, annotations hold the promise to significantly enhance information access, by enhancing the depth of analysis of today's systems. Currently, we have only started exploring the possibilities and only begin to understand how these valuable semantic cues can be put to fruitful use. To complicate matters, standard text search excels at shallow information needs expressed by short keyword queries, and here semantic annotation contributes very little, if anything. The main questions for the workshop are how to leverage the rich context currently available, especially in a mobile search scenario, giving powerful new handles to exploit semantic annotations. And how can we fruitfully combine information retrieval and knowledge intensive approaches, and for the first time work actively toward a unified view on exploiting semantic annotations.There was a strong feeling that we made substantial progress. Specifically, each of the breakout groups contributed to our understanding of the way forward. First, there is a need for further integration of symbolic and statistical methods with each adopting parts of the other's strengths, by focusing on types of annotations that are informed by and meaningful for the task at hand, and relying on automatic information extraction and annotation based on web scale observations. Second, the discussion contributed to the creation of a concrete shared corpus with state of the art semantic annotation-in particular a web crawl annotated with Freebase concepts-that will benefit research in this area for years to come.

In the past years various methods have been developed which require semantic annotations of Web services as an input. Such methods typically leverage discovery, match-making, composition and execution of Web services in dynamic settings. At the same time a number of automated Web service annotation approaches have been proposed for enabling application of these methods in settings where it is not feasible to provide the annotations manually. However, lack of effective automated evaluation frameworks has seriously limited proper assessment of the constructed annotations in settings where the overall annotation quality of large quantities of Web services needs to be evaluated. This paper describes an evaluation framework for measuring the quality of semantic annotations for a large number of real-world Web services from heterogeneous application domains. The evaluation framework is generally based on analyzing properties of Web service networks constructed from semantic annotations of the Web services. More specifically, we measure scale-free, small-world and correlation degree properties of the networks to evaluate the overall quality of annotations. The evaluation is demonstrated using annotations constructed semi-automatically for a set of publicly available WSDL documents containing descriptions of about 200 000 Web service operations.
