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 article covers the concept of a real expirable file system. This is a unique true-type file system, that integrates with the operating system for a period of time before it expires and is gone.

Expirable File System (EFS)
Disclosed is an idea for addressing the absence of a user creatable time based file
system. Typically, when user applications or programs create space it has to be done
within the confines of existing filesystems that are administered by users with root
authority. Or additional file systems have to be created by administrators with root
authority, and then manually deleted. The drawback is in a demanding environment,
users do not have the time to make requests, wait for administrators to set up file
systems, or in existing filesystems, space may run out, or the filesystem may not have
enough space to do the work needed by the user. Applications can create temporary
filesystems and remove them, but the application would have to run with root authority.
An additional solution is required for users who request on-demand and in such areas as
grid computing, where system time and resources are shared, and where user-based
applications do not have root authority, yet require dedicated filesystems for a period of
The core idea is to have an expirable file system, that can be generated by a user with
or without root authority. After an expiration period the filesystem will be removed. The
advantage to this is that users can define the request of how much space is needed, and
have an exclusive file system for the work needed to be done, without sharing the
resources with other users. A further advantage is that after the expiration period...
