Healthcare data originates in a wide variety of data formats, data models and vocabularies, making information interoperability a major challenge. Although many standards exist, and each one strives for a level of interoperability within its scope, in the aggregate these standards form an uncoordinated patchwork that thwarts interoperability. Furthermore, even when standards are used, translation between data formats, data models and vocabularies is still needed, for a variety of reasons. The Yosemite Project describes an ambitious roadmap for achieving semantic interoperability of all structured healthcare information. Based on RDF as the best available candidate for a universal information representation, this roadmap addresses both the need to 'standardize the standards' and the opportunity to crowdsource data translations that are still required for information interoperability.

The first indication of a new outbreak is often in unstructured data (natural language) and reported openly in traditional or social media as a new ‘flu-like’ or ‘malaria-like’ illness weeks or months before the new pathogen is eventually isolated. We present a system for tracking these early signals globally, using natural language processing and crowdsourcing. By comparison, search-log-based approaches, while innovative and inexpensive, are often a trailing signal that follow open reports in plain language. Concentrating on discovering outbreak-related reports in big open data, we show how crowdsourced workers can create near-real-time training data for adaptive active-learning models, addressing the lack of broad coverage training data for tracking epidemics. This is well-suited to an outbreak information- flow context, where sudden bursts of information about new diseases/locations need to be manually processed quickly at short notice.
