SEMANTIC FEATURES AND SELECTION
RESTRICTIONS
LEXICAL DATABASE OF THE
SYSTEM
LEXICOGRAPllER
an expert system
designed
consists of two basic components :
Lexical database (LBD)
is a vocabulary presented

Bibliographical database (BBD)
for every lexeme
or semantic feature

SEMANTIC FEATURE ACCORDING
TO U.WEINREICH
The notion of semantic feature is
associated
in the first place
with the name of
U.Weinreich (1967)
who proposed a useful distinction between
a paradigmatic semantic feature
and a transfer feature
In Weinreieh's conception semantic feature
serves several different purposes:
1) as a basis of semantic agreement
2) i deviant and metaphorical readings
3) provisional semantic contents
SEMANTIC FEATURES IN SYSTEMS OF NATURAL LANGUAGE PROCESSING
Semantic features belong to
obviously significant
NLP resources
having no equivalents
in existing dictionaries
The following problems of NLP
may be
listed where semantic features
are constantly made
use of:
Revealing predicate-argument relations
lexically
homonymous predicate word
3 lexically homonymous
noun
Combinability of verbs with adverbials
analysis of coordinate constructions
revealing anaphoric relations
Transfer semantic features
SEMANTIC FEATURES AND SELECTION RESTRICTIONS IN LEXICON AND GRAMMAR
In early 60-ies semantic features
were almost
unique theoretical
instrument of semantic analysis
We claim that different choice
of the case of the
subject
t in these examples has a semantic explanation.
An important
condition
is that this essential component
should have - in the semantic
representation of a sentence - the
status of an assertion or an implication
