Week 9 Semantics Flashcards
What is semantics?
• Knowledge of words including their meaning and relationships among words (lexical semantics)
• Meaning of syntactic units larger than a word is called phrasal or sentential semantics
(compositional semantics)
What is ‘reference’ in semantics?
• Meaning of word comes from associating it with
the real object, concept or individual it refers to
(the referent)
• Referring expressions used to identify a referent
• noun phrases (eg. the little dog, that girl, the chair)
• proper names (Paul, Mexico), pronouns in a noun
phrase (I, you, him)
• can have definite (my doctor) or indefinite (a doctor)
reference
• Can test referent knowledge through picture
naming
What is ‘sense’ in semantics?
- Abstract representation stored in mental lexicon
- Sometimes also termed “concept”
- Suggests the properties the entity may have
- Similar to other entities
- Distinguishing from other entities
- Help determine what the referent is
- e.g., Orange Juice
- Liquid produced by squeezing the round reddishyellow (orange), sweet or bitter, edible citrus fruit

Eg Animal (dog): +fur, +four leg
What are distinctive features?
Distinctive features: semantic feature or features that differentiates between category members (or between concepts generally) • Animal (Dog v Cat): canine v feline; barks v meows
What is a synonym?
Different word form, similar meaning, shared semantic properties
What is an antonym

What is hyponomy
