Semantic Features and Selection Restrictions in Lexicon and Grammar
Semantic features can be interpreted as a label for one or more semantic componets.
Examples of selection restrictions:
Namely motivated by some semantic component of a word.
Semantically motivated.
E.g: To believe
Incompatibility of contraries & Excluded neutrality
Two semantic features
On Semantic Invariant of the Class of Words with Genitive Subject
Verbs that can be used with genitive subject are called: genitive verbs.
They have semantic invariant.
The choice of the case of the subject is determined by a syntactic feature of a verb.
Examples: verb forms (passive forms) or predicatives
Significance of semantic features in NLP resources:
Subtopic
Transfer semantic features
for distinguishing
literal from deviant
or metaphoric interpretations
Use in revealing
anaphoric relations
in the text
Role in analysis
of coordinate
constructions
Combinability of verbs
with adverbials
relying on semantic concord
Disambiguation of lexically
homonymous words
Utilization in revealing predicate-argument
elations in parsing algorithms
Absence in existing dictionaries
Introduction to U. Weinreich's distinction of semantic features:
Semantic Features in Systems of Natural Language Processing (NLP):
Semantic conditions imposed on arguments by transitive features
Division of semantic features into categorial and transitive groups
Weinreich's purposes for semantic features:
basis of semantic agreement,
explanation of deviant readings,
addition of provisional semantic contents
Broader sense usage compared to transformational grammar (TG)
Paradigmatic vs. transfer features
