File 6.0-6.4: Semantics (F) Flashcards
What can semantics be divided in?
- Lexical semantics
- Compositional semantics
lexical semantics
Lexical semantics deals with the meanings of words and other lexical expressions, including the meaning relationships among them.
compositional semantics
Compositional semantics is concerned with phrasal meanings and how phrasal meanings are assembled. The meaning of sentences and how they are assembled.
What are the two aspects of linguistic meaning?
- Sense
- Reference
How do we store word meanings?
a. Dictionary-Style Definitions
b. Mental Image Definitions
c. Usage-Based Definitions
Dictionary-Style Definitions
Word meanings store in our minds with words describing words.
Mental Image Definitions
Word meanings stored in our minds as a mental image. Think of the words Mona Lisa.
prototype
For any given set, a member that exhibits the typical qualities of the members of that set.
So, for a mental image based storage one image represents a word, but is often very specific and the word can mean more than one idea so the image isn’t always a good representation.
Usage-Based Definition
A characterization of a word’s sense based on the way that the word is used by speakers of a language.
In what way can words semantically be related?
- Hyponymy (sister terms)
- Synonymy
- Antonymy
hyponomy
A meaning relationship between words where the reference of some word X is included in the reference of some other word Y. X is then said to be a hyponym of Y, and conversely, Y is said to be a hypernym of X. (See also Sister Terms.)
For example, consider the words dog and poodle. The reference of dog is the set of all things that are dogs, while the reference of poodle is the set of all things that are poodles.
sister terms
Another word for hyponymy, when the reference is on the same level in the hierarchy.
synonymy
Two words are synonymous if they have exactly the same reference. (couch/sofa, etc.)
antonymy
Two words that are opposite of each other.
In order for two words to be antonyms of one another, they must have meanings that are related, yet these meanings must contrast with each other in some significant way.
In which ways can words be opposite of each other?
- Complementary
- Gradable pairs
- Reverses
- Converses
complementary antonyms
Two words X and Y are complementary antonyms if there is nothing in the world
that is a part of both X’s reference and Y’s reference. (married/unmarried)
gradable antonyms
Gradable antonyms typically represent points on a continuum, so while something can be one or the other but not both, it can also easily be between the two. (wet/dry, hot/cold)
reverses antonyms
Reverses are pairs of words that suggest some kind of movement, where one word in the pair suggests movement that “undoes” the movement suggested by the other. (put together/take apart, ascent/descent)
converses antonyms
Converses have to do with two opposing points of view or a change in perspective: for one member of the pair to have reference, the other must as well. (lend/borrow, send/receive)
proposition
The claim expressed by a sentence is called a proposition.
The sense expressed by a sentence. Characteristically, propositions can be true or false, i.e., have truth values.
truth value
The ability to be true or false is the ability to have a truth
value. (It doesn’t have to be true!)
truth conditions
The conditions that
would have to hold in the world in order for some proposition to be true are
called truth conditions.
What kind of propositional relationships are there?
- Entailment
(- Mutual entailment) - Incompatible
entailment
A relationship between
propositions where a proposition p is said to entail another proposition q just in case if p is true, q has to be true as well.
a. All dogs bark.
b. Sally’s dog barks.
