We must remind some linguistic aspects which represented the basis
of our definition of morphological attributes and of the flexionary
classes from the Romanian language thesaurus which we have defined.
The non-flexible words have a unique form of representation and
are easy to analyze from a lexical point of view. The flexible
ones change their form in different syntactic situations, i. e.
they can be declined or conjugated. The sum of all the flexionary
forms of a word represents its paradigm
P:: + {Root + Flective}
The Root is compulsory for any flexionary unit and it is
also the element that carries the unit of content. In the paradigm,
the root may vary due to phonetic alternances or irregular forms.
The Flective represents the differentiating element from
the paradigm. Unlike the root, it can be zero. The flective varies
according to the grammatical categories of the part of speech,
i. e. in the case of nouns the variation corresponds to number,
case, gender and determination; in the case of verbs, it corresponds
to mood, tense, number and person.
3. Ways of determining the structure of the computerized Romanian lexic
The computerized Romanian lexical thesaurus is supposed to be
the fundamental theoretical basis for building the automatic instruments
destined for the further work on the linguistic information specific
for our language. This information is conceived and structured
so that it allows the development of a wide range of applications.
Up to the present moment, we have focused on elaborating a spelling
check soft (which corrects and also generates forms), and the
base contains only the specific morphological attributes. We have
to mention here the attributes introduced up to the present moment
have allowed to create a first version of a morphological spelling
check, also offering the possibility to pursue work and to create
a complete morphological analyzer (which is now only at the stage
of the automatic conjugation of verbs). The thesaurus is a primary
basis, which can be enriched with new specific attributes for
the different fields of language. In order to solve the specific
informatic instruments, we must use specific generators of dictionaries.
The purpose of this application is to obtain better dictionaries
containing the minimal information necessary for solving the specific
applications.
3.1. A definition of the flexionary classes
The variable part form from flexion is called the flective. Within
the same part of speech, the flectives corresponding to different
grammatical categories can have different forms. This is the criterion
of grouping words belonging to the same part of speech in flexionary
classes. The flectives which characterize a flexionary class are
the same for all the words which belong to that class. The flexionary
class associated to a part of speech determines the sum of flectives
which characterize the class and, implicitly, the sum of attributes
corresponding to the grammatical categories accepted by the classical
grammar.
