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.

TITLE User Defined Call Forwarding
Christensen & Soren Sorensen
User defined call forwarding enables
incoming calls to be forwarded on the request of the calling party.
In a public safety communication
system, where the reliability of
contact between users is a must, is it important that users are being
redirected if it not possible to obtain a connection for all call types. Group
calls are typically several users in a call whereas phone and private calls
only are between two parties.
1) When user "A" makes a private call to
user "B" and user is busy or doesn’t answer. User "A" will
get a reject/no answer back.
2) When user "A" makes a phone call to user "B" and user is
busy or doesn’t answer. User “A” will either get a reject/no answer back or go
to an answering machine.
This can in some cases be acceptable but in most cases it is important for user
"A" to get into contact with a specific user or a user within user
"A" group without making a group call.
Solution to the Problem(s)
In order that the idea may fully be understood, the
following example is given. My idea is to build a list of private call numbers
/ phone call numbers in the subscriber, so that when user "A" gets a
“reject” or no “answer back” when making either a private call or phone call to
user "B", the User "A" subscriber will automatically try to
make a new attempt to user "B" maybe up to 3 times with a certain
time interval. If it...
