The lexical route is the process whereby skilled readers can recognize known words by sight alone, through a "dictionary" lookup procedure. [ 1 ] [ 4 ] According to this model, every word a reader has learned is represented in a mental database of words and their pronunciations that resembles a dictionary, or internal lexicon.
Lexical semantics (also known as lexicosemantics), as a subfield of linguistic semantics, is the study of word meanings. [ 1 ] [ 2 ] It includes the study of how words structure their meaning, how they act in grammar and compositionality , [ 1 ] and the relationships between the distinct senses and uses of a word.
This can be explained by models that do not assume a distinct level between the semantic and the phonological stages (and so lack a lemma representation). [3] During the process of language activation, lemma retrieval is the first step in lexical access. In this step, meaning and the syntactic elements of a lexical item are realized as the lemma.
Before the 1950s, there was no discussion of a syntax–semantics interface in American linguistics, since neither syntax nor semantics was an active area of research. [17] This neglect was due in part to the influence of logical positivism and behaviorism in psychology, that viewed hypotheses about linguistic meaning as untestable.
The latter, semantic network theory, proposes the idea of spreading activation, which is a hypothetical mental process that takes place when one of the nodes in the semantic network is activated, and proposes three ways this is done: priming effects, neighborhood effects, and frequency effects, which have all been studied in depth over the years.
BabelNet is a multilingual lexical-semantic knowledge graph, ontology and encyclopedic dictionary developed at the NLP group of the Sapienza University of Rome under the supervision of Roberto Navigli. [1] [2] BabelNet was automatically created by linking Wikipedia to the most popular computational lexicon of the English language, WordNet.
Pronouns are a lexical category. Pronouns have the person feature, which can have a value of "first", "second", or "third". English pronouns also have the number feature, which can have a value of either "singular" or "plural". As a result, we can describe the English pronoun "they" as a pronoun with [person:3] and [number:plural].
Generative lexicon (GL) is a theory of linguistic semantics which focuses on the distributed nature of compositionality in natural language.The first major work outlining the framework is James Pustejovsky's 1991 article "The Generative Lexicon". [1]
