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.

Extended POI Search System with Question Generating Capability
The disclosed is a speech-based search system that could be used for POI (Point Of Interest) search, music search and etc. In order to perform search by user-spoken key-words, some of the conventional search systems allow users to say an additional key-words to narrow down the search results. However, the additional key-word need to be selected by the user. The
o question to be answered by the user so to narrow
o question is something like "Is it related with <keyword > ?". The keyword is automatically determined by this system so to maximize the mutual information by adding it. The new part of this approach includes taking the summation of the mutual information for all the possible word sequences, which are the N-best outputs of the speech recognizer. The summation introduces options of the weighting techniques using acoustic likelihood and joint
probability of the word sequences.
The user is supposed to answer the question with "Yes" or "No". If the answer is "Yes", the keyword is added to all the possible word sequences. If the answer is "No", a pseudo keyword indicating the negation of the keyword is added to them. Then, the search and the keyword generation are performed again with the enhanced word sequences. These operations are repeated until the user finds what he/she wants in the search results.
The probability of the pseudo keyword is given by...
