semantics for universal search and discovery
DESCRIPTION
WebLib has recently won a prestigious U.S. challenge.gov award with its NLMplus entry, a large scale semantic search and knowledge discovery application that makes innovative use of the National Library of Medicine’s vast collection of biomedical data and services.The NLMplus app (http://nlmplus.com) combines a number of leading-edge semantic knowledge resources and technologies, such as a biomedical knowledge base, a semantic search engine, a distributed search engine, and a variety of smart content analysis and discovery services. Users can concurrently access 60 NLM databases to find trusted information ranging from consumer health topics to drugs and from news to clinical trials and translational medicine. One of the important innovations of NLMplus is WebLib’s Semantic Search Engine, which typically produces relevant search results with improved precision and recall from 1.6 million PubMed Review articles, which are semantically indexed and searched on a WebLib server. The NLMplus application also sends conceptually enhanced user queries to NLM’s PubMed system of more than 21 million citations from the biomedical literature, life science journals, and online books.Providing flexible access to heterogeneous databases is a common challenge in medical libraries, biomedical research institutions and the health care industry. The same is true for non-biomedical content and applications. WebLib’s domain independent semantic indexing and searching of local databases, in combination with universal search and discovery solutions for free and fee-based content allows all types of organizations to better serve their diverse user communities, including the public, researchers, professionals, and policy and decision makers.TRANSCRIPT
