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.
This invention presents a method that allows a multi-modal IP based IVR system to provide the user with a visual cue when the operator joins the call.

Visual notification of a stream change in an IP call.
This invention solves the problem described above by introducing a new payload type into the VoIP audio stream. A special "stream switch" packet will be inserted in between the transition of the "on hold" audio stream and the new "operator's speech" stream which is about to take over. On the client side, the stream handler will propagate that message up to the multi-modal application which can then provide a visual cue to the user. On the IVR side there will be a lower level streaming engine that accepts audio prompts from the system, packetizes them, and transmits them to the multi-modal client. The low level streaming engine will provide API's to accept audio and will also provide an API that indicate a stream switch. Here is a flowchart that shows how the IVR will interact with the audio layer.

On the client side the stream handler keys off of the "stream switch" payload type and propagates that information up to the multi-modal client. The multi-modal client will put a visual cue on the screen to alert the user that the operator has joined the call.
