Semantic Feature
Semantic feature is a notational method which can be used to express the
existence or non-existence of pre-established semantic properties by using
plus and minus signs.
Semantic properties: The components of meaning of a word.
Meaning as collection of properties/features typically with two possible
values (+ / -)
Example of componential analysis:
baby is [+ young], [+ human], [+animate]

Components of meaning
The meanings of the individual items can be expressed by combinations of
these features:
man girl boy woman horse window
ANIMATE + + + + + -
HUMAN + + + + - -
MALE + - + - + -
ADULT + - - + + -

Neutralization
child and adult are not specified for sex, man ( = 'human being') is
unspecified for both sex and adulthood, and the adjective female (-MALE)
is unspecified for both species and adulthood. This feature represented by
the symbol [ o ].
man: +HUMAN (OMALE) (OADULT)
adult: +HUMAN +ADULT (OMALE)
child: +HUMAN -ADULT (OMALE)
female: (OHUMAN) (OADULT) –MALE
Men have lived on this planet for over a million years

Synonym
Synonym: words that have the same meanings or that are closely related in meaning [more than one form having the same meaning ]
e.g.: ‘John is grown up.’ entails ‘John is an adult.’
Other examples:
1. answer = reply
2. Almost = nearly
3. Buy = purchase
4. Freedom = liberty
‘sameness’ is not ‘total sameness’- only one word would be appropriate in a sentence.
E.g. Sandy only had one correct answer on the test. (but NOT reply)

Antonym
Antonym: words of opposite meaning.
For example: quick × slow, big × small, old × young, male × female, true ×false, alive × dead.
Antonyms are divided into two parts.
Gradable antonyms: they can be used in comparative constructions.
such as the pair big × small, like
This book is bigger than that book. ×
That book is smaller than this book.
Non-gradable Antonyms: Such antonyms have “complementary pairs, comparative constructions and negative of one member does imply the other.
For example : The person is not dead, it means that the person is alive. 5/13/2014

Polysemy
A word which has multiple meanings related by extension,
e.g. bright: ‘shining’ ; ‘intelligent’
Shining = It is a bright sunshine.
Intelligent = He is a bright child.
‘Head’ of the body and the person at the top of a company.
‘Foot’ of a body and of a mountain and of the bed or chair.

Hyponym Words whose meanings are specific instances of a more general word.
When the meaning of one form is included in the meaning of another, the relationship is describedas hyponym. For example:
Flower: daffodil
Animal: dog
Dog: poodle
Vegetable: carrot
Tree: banyan
: …
:
The concept of “inclusion’ involved here.
Dog is a hyponym of animal. Animal is the superordinate of dog.
Dog is the specific lexical item (word), but Animal is the general one.
When we say that dog is a hyponym of animal, we mean that dog is a type of animal. 5/13/2014
Animal dog, cat, cow, camel, lion, giraffe,
Superordinate Hyponyms (Co-hyponyms)

Incompatibility
It is containing at least one feature contrasting with a feature in the other.
e.g. Woman: child
She is a woman. [ entails that she is not a child.]
the meaning of woman is incompatible with child because of the clash
between + ADULT and -ADULT

12
Componential Analysis
Justifying a componential analysis means showing that the contrasts and
combinations of meaning one has recognized are necessary and sufficient
to explain relevant data.
Entailment: it is a relation between sentence meanings, or propositions.
e.g.
'The secretary is a woman' entails 'The secretary is an adult.‘
'I met two boys' entails 'I met two children.‘

13
Inconsistency:
It is a situation in which two statements are different and cannot be true.
X is inconsistent with Y
If X is true, Y is false; also, if Y is true X is false.
'The secretary is a woman' is inconsistent with 'The secretary is a man.‘
'Her best pupil is a boy' is inconsistent with 'Her best pupil is an adult.'

Tautology and Contradiction
Some types of tautology and contradiction, too, can be defined in terms of
hyponymy and incompatibility, as may be gathered from these examples:
Tautology is a way to express something by repeating or saying it in a
different way.
'That man is an adult' is a tautology.
Contradiction is a difference between two statements, ideas, beliefs or
opinions about something that cannot be true.
'That boy is a woman' is a contradiction.

Taxonomy
Taxonomy is the relationship between the general term and the instance. It
is often be described using hierarchical diagram.
There are two types of taxonomy:
BINARY TAXONOMY
MULTIPLE TAXONOMY

Taxonomy
BINARY TAXONOMY:
The absoluteness of the boundary needs explanation. It might be pointed
out that in objective, physical terms, there is no clear-cut opposition
between life and death;
'John is alive' is inconsistent with 'John is dead‘
'John is dead' entails 'John is not alive‘
'John is alive' entails 'John is not dead'.

17
Taxonomy
MULTIPLE TAXONOMY
Examples of this type are semantic classes dealing with types of metal,
species of animal, or tree, or fruit, etc., primary colours, noises ('bang',
'crash1, 'clatter', etc.) and types of vessel ('vase', 'mug', etc.).
the absoluteness of boundaries may be justified in logical terms, for
example by the contradictoriness of a statement like
'This copper jug is made of silver'.
'This red book is brown'

Relative Oppositions
Relative oppositions imply that there are several semantic features on
which the opposition rests. The verb to leave means ‘to go away from’ and
its opposite, the verb to arrive denotes ‘to reach a place, esp. at the end of
a journey’.
It is a relation which involves contrast of directions, for example:
own/belong to , parent/child, teacher/pupil
5/13/2014
19
The contrast between two relative features consists in the fact that the two arguments
(a and b in the diagram) may be related either in one order or in another.
John is the parent of James,
James is the parent of John.
a b
Parent of
Child of

My uncle owns this car is synonymous with This car belongs to my uncle.
'John s married to Susan' entails 'Susan is married to John'.
'Clive is taller than Bill' is inconsistent with 'Bill is taller than Clive.' 'Clive is taller.
'The king is in his counting house and his counting house is in his castle'
entails 'The king is in his castle.' [transitivity ]
John is the parent of George, and George is the parent of Tom ' is
inconsistent with * John is the parent of Tom '. [ intransitivity ]
