The indexing consists in characterising
the content of a document by a certain number
of key words. This means you need to know the
list of these key words to make it effective.
Indexing achieves its limits
very quickly, as uncertainties related to synonyms
and the absences of relations between the key
words or index becomes numerous.
THESAURUS MANAGER answers
these difficulties proposing in a very simple
way. It proposes an unlimited list of terms organised
by semantic affinity and relation links. Its
original graphical presentation makes it very
easy to understand and very easy to parameterise.
THESAURUS MANAGER is in fact
an extra database, connected to GARGANTUA and
intended to increase the relevance of search
by widening it with the domain of the expressions
used.
1) The
different types of connections between expressions
THESAURUS MANAGER manages the five principal
relations or functions between the terms, such
as those defined by standard ISO 2788, as follows
:
- USE
use
- UF use
for
- BT broader
term
- NT narrower
term
- RT related
term
The relations of equivalence USE and UF include
the functions of synonymy (example :
aspirin, acetylsalicylic acid), and quasi
synonymy which apply according to the context
(example :
glasses, telescope), as well as inclusions.
The hierarchical relations BT and NT include
the generic relation (example :
BT vertebrates, NT mammals, birds), hierarchical
relation all / part (example :
BT north area, NTG north state) and the
relation for the example (example :
BT seas, NT the Baltic sea, the Caspian sea:
which are not seas types but some examples).
The related term RT is
defined for the terms linked by the meaning only,
without hierarchical connection (example :
: toxicity, RT poisons). It is not a synonym,
a quasi synonym, a broader term or a narrower
term.
An explanatory note can be associated
to each term.
2) The
user interface - the classification of the
data in a thesaurus database
THESAURUS MANAGER is
organised in a tree structure in which each level
represents a definite classification of the terms.
The first level corresponds
of fields of the Thesaurus, then proceeds the
secondary fields or semantic fields, then the
various levels of the descriptors.
The number of levels as well
as the number of terms per branch is not limited.
THESAURUS MANAGER allows
the creators, when they build up a Thesaurus,
all types of classification and ordering. It
also allows an easy reorganisation of the subsets
through simple functions such as "move" or "link" as
well as the handling of the terms or the branches
by drag and drop.
Its comprehension is easier,
since the documentary system to which it must
apply is well organised.
3) THESAURUS
MANAGER and GARGANTUA
Connected to GARGANTUA, THESAURUS
MANAGER not only allows refining or
extending a search, but also to control the
indexing by using vocabulary limited to the
descriptors.
THESAURUS MANAGER is used for
:
- Index search
- Full text search
and in connection in a client Windows mode or
in a browser mode.
4) Particular
functions
The content of THESAURUS
MANAGER can be exported in whole or
part, in xml format or as a list of terms.
On the other hand, importation
of lists of terms files or xml files ensures
the fast addition of data, even the importation
of a complete Thesaurus base related to a documentation
database.
The content can be printed in
individual branches or in its totality.
