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.

Use of Computations in Panels for Decision Support
A method is described to define computations on a panel based on data
fields in the panel and display the results of the computations on the panel.
A panel designer creates a panel to view or edit data from tables in the
database. The data on the panel may be used in computations. The
computations may be based on data input on the panel or retrieved from the
database and displayed on the panel. The results of these computations may be
used as final data values on the panel or as input into another panel as a
The panel may also contain rows of data that are repeated multiple times on
the panel. Within a row, the designer may include a computation that applies to
data fields in the row. When the row is repeated on the panel, the designer also
wants the computation to be repeated.
In accordance with the new method, the designer is allowed to define
computed fields on the panel in addition to table fields. Table fields are defined
as input and/or output fields on the panel and correspond to columns in the
tables on the database. Computed fields are output only fields on the panel.
The computation is expressed as a formula which contains table fields, constants
or other computed fields, arithmetic operators or simple functions. Arithmetic
operators allowed are +, -, * and /. The function must apply to a repeating field
on the panel and may be Sum, Average, Min, Max or Count.
The method also allows the designer to define a row on the panel which
contains data fields and computed fields. This row may be repeated multi...
