Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Information Scaling Function for Synonym Retrieval
Disclosed is an algorithm for reducing noise in a conversational entry
document retrieval system caused by the introduction of synonyms to broaden
the retrieval scope.
Each entry keyword is referenced through a comprehensive totally inverted
synonym data base and the appropriate synonyms for the keyword also become
search keys for document retrieval. This technique lowers the requirement for
preciseness of the input and provides a more comprehensive search of the data
base, but it has the drawback of including synonyms that are only remotely
connected to the meaning of the input keyword and therefore documents may be
retrieved that may be completely unrelated to the intended search. The disclosed
function addresses this problem by taking advantage of the linguistic nature of
the organization of the synonym dictionary. The synonym relationships in the
synonym dictionary override alphabetical order in the prioritization for displaying
synonyms of a given word. Synonyms of a keyword are retrieved and delineated
by "sense" and kept in descending affinity order.
A retrieval score, numerical weight, is determined for each keyword and each
of its synonyms. However, before they enter into the computation of respective
document retrieval scores, the numeric contribution to a score made by each of
the synonyms of a keyword is scaled according to its relative "affinity" position in
the list of synonyms that it came from. De...
