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.

Chord Spelling and Melody Translation
An interactive graphic display system can be used to spell musical chords
and to translate melodies from one key to another.
Chord Spelling: Fig. 1 shows an example of a display frame that could be
used for chord spelling. Input to the system can be by directly indicating items in
the menu at the bottom of the frame (using, for example, a light pen or a cursor)
or by pressing predefined keys on a keyboard. The individual notes of a chord
can be entered into the system for display in an area 1. The system will then
display the name of the chord in an area 2. Conversely, the name of a chord can
be entered into the system (as above, using a light pen, cursor or keys to select
items from the menu) and the system will generate and display the individual
notes of the chord.
Melody Translation: Fig. 2 shows an example of a display frame that could
be used for melody translation. The user would select FROM KEY and the key in
which music is to be entered. The user would then select TO KEY and the key
into which he wants the music to be translated. He can also elect to have the
translation up or down one or more octaves. The notes entered into the system
will appear in an area 3. The translation will appear in an area 4.
