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.

Method For User Controlled Variable Rate of Scrolling
By using a locator device as an "accelerator" as well as direction indicator for
scrolling, a user can precisely vary the scrolling rate and scroll long distances
with minimal "hands-on" effort.
Current scrolling techniques using locators typically require that the locator
be continuously moved to cause continuous scrolling. This results in the
undesired consequence of requiring the user to pick up the locator and reposition
it when it reaches the edge of the user's workspace.
By using the locator as an "accelerator" such that the rate of scrolling is
proportional to the displacement of the locator from some reference position.
The direction of scrolling is established by the direction of movement from the
reference position. The reference position is established by pressing a "scroll
button" on the locator device. If the locator is moved further, the scrolling rate is
increased. If the locator is moved back towards the reference position, the
scrolling rate is decreased. As such, a user may very quickly scroll through large
amounts of data, yet slow to a comfortable "browse" rate for scanning.
