A search can be launched and execution controlled by the use of a set of control buttons, which operate much in the manner of media control buttons, as in Windows Media Player(tm), or RealPlayer(tm). The figure below shows the control buttons, as they would appear immediately after execution of a search.
When you press the Fetch button,
the set of queries in the Query Editor is submitted to multiple
user-selected search engines. The retrieved results (documents) are
fetched from their respective sources and each document is then parsed into
sentences and analyzed for concept associations (e.g. protein-protein
associations). Agilent Literature Search uses a set of lexicons for defining concept names
(and aliases) and association terms (verbs) of interest. The concept lexicon supplied with this version
of Agilent Literature Search contains gene/protein names and
aliases. An association is extracted for every sentence containing at
least two concept names and one verb. Associations are then
converted into interactions, which are further grouped into a network.
The sentences and source hyperlinks for each association are further stored as
attributes of the corresponding interactions .
At any point in the search operation, you can Abort the
operation by pressing the button. This terminates the
source with no possibility of recovery.
Once the documents are fetched from their respective sources, you have the
additional option to Pause the operation while document parsing
and analysis is underway. You will see a Pause button
, in the
place where the Fetch button was displayed. If you
press this button, Agilent Literature Search interrupts the search in
progress, with the possibility to Continue . If you then press the Continue button
, then Agilent
Literature Search
resumes execution.
When you are finished with a search operation, the contents of the
Terms, Context, and Query Editor
panels remain intact. You can edit them for subsequent refined
searches or modified searches. Or you can clear the contents of the
Terms, Context, and Query Editor
panels by pressing the Clear button.
The Clear button can also be used to clear the contents of the
Terms, Context, and Query Editor
panels while you are building up your query strings prior to your
initial search.
The table below summarizes the functionality of the search control buttons.
Clear | ![]() |
