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.

Abstract: Described herein is a system that allows a user to send an alpha-numeric message from a stan- dard touchtone phone.
The set-up basically consists of a Paging System provided with an algorithm such that is able to recognize and execute a customer's '?one command" instruction. The Alpha-Call mode engagement as well as the sys- tem's instructions, are done by sets of two tones as described below.
To each user, there will be either a X amount of minutes or a Y number of tones allowed to deliver each message.
Depressing the '*' and then any of the numerical keys (except #I), will enable the character imprinted on the upper left corner of the key.
Depressing "#" and then any of the numerical keys (except #l), will enable the character on the upper right corner.
Depressing any key (except 1, 0, *, #), will enable the upper middle character.
