SEMANTIC FEATURES AND SELECTION RESTRICTIONS
SEMANTIC SELECTION FEATURES RESTRICTIONS LEXICON AND GRAMMAR
semantic features can be interpreted as a label for one or more semantic components in the semantic decomposition of a lexeme.
SEMANTIC FEATURE ACCORDING TO U.WEINREICH
who proposed a useful distinction between a paradigmatic semantic feature and a transfer feature.
Weinreieh's conception semantic feature
1) it is regarded as a basis of semantic agreement (examples pretty girl vs. *pretty man)
it explains deviant and metaphorical readings (as in a grief ago, before the wall)
it adds provisional semantic contents to a potentially ambiguous word
SEMANTIC FEATURES IN SYSTEMS OF NATURAL LANGUAGE PROCESSING (NLP)
The following problems of NLPi
Revealing predicate-argument relations in parsing algorithms
Disambiguation of a lexically homonymous predicate word
Disambiguation of a lexically homonymous noun by addressing transfer features of the predicate.
Combinability of verbs with adverbials designating time, place, reason, purpose, instrument etc.,
It is often necessary to carry out a transformation opposite to conjunction reduction, and semantic agreement
Semantic features may be useful in the proce- dure of revealing anaphoric relations in the tex
Transfer semantic features may be used to distinguish texts allowing for literal interpretations from deviant or metaphoric
LEXICAL DATABASE OF THE SYSTEM
LEXICOGRAPllER
expert system designed, in the first place, for the purposes of natural language processing.
two basic components:
bibliographical database (BBD)
vocabulary consists of some 12.500 words.
ON SEMANTIC IN-VARIANT OF THE CLASS OF WORDS WITH GENITIVE SUBJECT
Verbs that can be used with genitive subject will be called genitive verbs.
There are two semantic components, different but cognate, such that at least one of them is always present in every
negative sentence
with the
genitive subject construction
negative sentences with the nominative and with the genitive subject will have different meanings
lexical database (LBD)
is a vocabulary
presented in a machine readable form and consisting of several domaines
included in the database there are such features as:
[ + Speech act verb]
[ + Per- formative verb]
[ + Verb of motion]
