WebLib's PolySearch enterprise search engine is a best-of-class domain independent semantic indexing and search solution built on top of the open source Solr/Lucene enterprise search platform.
PolySearch is powered by WebLib's proprietary Web Knowledge Base(TM).
The Web Knowledge Base contains millions of concepts and billions of semantic entity pairs and semantic triples covering the breadth and depth of ideas and their relationships in biomedicine, energy and the broadest spectrum of human endeavors.
The Web Knowledge Base can be customized with customer provided thesauri, taxonomies and other semantic resources.
The PolySearch Semantic Enterprise Search Engine enables clients (content providers, publishers, the media, government agencies, universities and other organizations) to create new knowledge products or enhance their existing products and services with powerful semantic search and Semantic Web capabilities.
