"UMBEL Concept Plain Tagger This plain tagger uses UMBEL reference concepts to tag an input text. The OBIE (Ontology-Based Information Extraction) method is used, driven by the UMBEL reference concept ontology. By plain we mean that the words (tokens) of the input text are matched to either the preferred labels or alternative labels of the reference concepts, with the match basis denoted by color. The simple tagger is merely making string matches to the possible UMBEL reference concepts."

ShriGB - A Semantic Financial Search Engine Leveraging Big Data & Extracting Valuable Insights

Symbolab is a semantic web search engine for math and science. It allows users to search for equations, formulas and expressions using mathematical symbols and scientific notations as well as full text search. The stated goal of the site is to provide the most relevant search results that are theoretically and semantically similar, rather than visually.

The intention of this service is to simplify a common task in the work of RDF developers: remembering and looking up URI prefixes. You can look up prefixes from the search box on the homepage, or directly by typing URLs into your browser bar, such as http://prefix.cc/foaf or http://prefix.cc/foaf,dc,owl.ttl.

"Omnity is based on fundamental advances in associative semantic search technology, through which we create landscapes of meaning-based relationships arising from the semantic signatures of entire documents. In this manner, the knowledge contained within whole documents can be deeply inter-connected, solely through shared ideas."
