SEMANTIC FEATURES AND SELECTION RESTRICTIONS

1. LEXICAL DATABASE
OF THE SYSTEM

Expert System for natural
language processing purposes

It consists of 2 basic components:

Lexical Database (LBD)

Consists of
several domains

Vocabulary presented in
machine-readable format

The user can obtain
information about:

--Morphology
--Syntactic features
--Semantic features
--Prosody
--Referential features
of individual lexical items.

Bibliographic Database (BBD)

Contains bibliographic information
on individual lexemes

The vocabulary
consists of
about 12,500 words

Syntactic and Semantic information
cannot be found
in existing dictionaries

3. SEMANTIC FEATURES
IN SYSTEMS OF
NATURAL LANGUAGE PROCESSING
(NLP)

Semantic features belong to NLP resources

You can list NLP problems
in which features are constantly used

Revealing
predicate-argument
relationships in
parsing algorithms

Disambiguation of a
lexically
homonymous
predicated word

Combination of verbs
with adverbs
that designate
time
place
reason
purpose
instrument, etc.

Semantic features
can be useful
in the process

Transfer semantic features
can be used to
distinguish texts that allow
liberal interpretations
of deviant or metaphorical texts.

4. SEMANTIC FEATURES AND SELECTION RESTRICTIONS IN LEXICON AND GRAMMAR

Evolution of semantic theory

Role in regulating selection restrictions

Examples

Neg-Raising
predicates

Semantic distribution
of conjunctions

Predicates introducing
indirect question

Semantic motivations
for syntactic behaviors

5. ON SEMANTIC INVARIANT OF THE CLASS OF WORDS WITH GENITIVE SUBJECT

Focus on

The construction with genitive subject in Russian,

Specifically in contrast with the nominative case.

Identification of two semantic components

'X exists'

Determines the case
of the subject
in negative sentences.

'X takes place'

Clarification that if the verb's meaning doesn't definitively predict the presence of the presupposition of existence

Example

Demonstrating
how the
presence or
absence
of the presupposition
of
existence affects
the
choice of case
for the subject.

2. SEMANTIC FEATURE
ACCORDING TO U. WEINREICH

U. Weinreich proposed

A distinction between a paradigmatic semantic feature and a transfer function.

The distinction made it possible to use

The notion in
a broader sense

than in
transformational
grammar

The semantic feature has several purposes:

As a basis for
semantic agreement

Explain deviant
and
metaphorical readings

Add provisional semantic
content to an
ambiguous word
