Over the past decade, online crowdsourcing has established itself as an emerging paradigm that industry and government have been using to harness the cognitive abilities of a multitude of users distributed around the world. In this context, microtask crowdsourcing has become the method of choice for addressing a wide range of diverse problems. Microtasks typically require a minimum of time and cognitive effort, but combined individual efforts have made it possible to accomplish great achievements. The goal of this paper is to contribute to the ongoing effort of understanding whether the same success that microtask crowdsourcing has achieved in other domains can be obtained in the field of social news curation. In particular, we ask whether it is possible to turn online news curation, typically a social and collaborative activity on the Web, into a model in which curatorial activities are mapped into microtasks to be performed by a crowd of online users.

Design is a knowledge intensive activity, which depends on information to be undertaken. Previous designs, recent innovations, new techniques and materials must be taken into account when working on a new project, whatever its nature. Therefore, retrieving appropriate information is of paramount importance to the design process. Information retrieval is an established field, which has seen great progress in recent years. However, as the amount of unstructured information available increases, it becomes harder to retrieve the most relevant information using standard techniques and, frequently, users end up with results that don't fulfill their information needs. In this paper, we present an approach to improve retrieval using query expansion through ontologies allied to faceted navigation. We constructed the Ontoogle tool, which uses an ontology describing a domain to expand the query and define result ranking and presentation using Faceted Navigation. This proposal was evaluated in a case study and the results indicate that this approach contributes to increased satisfaction and confidence of users during their search process.
