SiteScreen is a product of Crystal Semantics. Crystal Semantics’ patented semantic classification technology is called Sense Engine™ and is the result of over 17 years of product development. 

The Sense Engine is the brain child of Professor David Crystal OBE, one of the world's leading linguists. The technology has benefited from a team of 40 lexicographers and encyclopedists that have worked their way through all the words and senses in English that are likely to discriminate and disambiguate contexts, and to give them appropriate classification.

Unlike other 'contextual' technologies that simply leverage bidded keywords, the Sense Engine will analyze all words on a single page and is designed to pinpoint the exact subject of each page.

Similarly, unlike statistically based algorithmic or natural language technologies, Sense Engine™ does not require training in order to identify relationships between words. This exhaustive work has been created using expert linguistic knowledge, to be capable of identifying the key information required to identify the context(s) on any given page.
