Text and Bibliographic searching
Introduction
As well as being a database of sequence information, DGENE is also a bibliographic patent
database complete with titles, abstracts and other front-page publication details. Each DGENE
sequence record includes a concise abstract per sequence written by a Thomson Reuters subject
specialist 1 . In addition, there are sequence-specific searchable details, including organism name,
Patent Sequence Location (PSL) and value-added feature table indexing. DGENE therefore offers
a number of different ways to refine sequence results searching by subject and dates, and is also an
excellent value-added resource for word-based searches on a wide variety of life science topics.
DGENE Basic Index
An unqualified search query is automatically searched against the Basic Index of DGENE. The
Basic Index comprises: Title (TI), Abstract (AB), Organism Name (ORGN), Description (DESC)
and Keywords (KW). It does NOT include Molecule Type (MTY) or the feature table (FEAT).
Title (TI)
The title comes from WPINDEX and provides a concise summary of the patent as a whole,
comprising the scope, novelty and practical application(s) of the overall invention.
Abstract (AB)
Concise summary of the sequence and its context within the overall invention, including features,
applications, preparation, analysis, etc depending on the content and focus of the patent document.
Organism name (ORGN)
The organism name is the name of the source organism for the sequence. This is generally in the
latin form: genus species. Synthetic (or unidentified) is indexed for sequences which were
prepared synthetically, or where the biological origin was not described in the patent document.
Description (DESC)
A concise description of the specific sequence, e.g. Human alcohol-dehydrogenase enzyme;
Human alcohol-dehydrogenase gene; DNA probe used to detect alcohol-dehydrogenase; etc
Keywords (KW)
A field comprising words and terms indexed by the abstractor which relate to the specific
sequence, rather than simply to the invention as a whole. The field features some useful
standardized terminology, e.g. ss (single stranded) or ds (double stranded) sequences. See note.
note
The DGENE Keywords (/KW) field often incorporates Gene Ontology (GO)
indexing. Look up GO terms of interest at: http://amigo.geneontology.org/.
