2. Semantic Features General Issues 1. Componential Analysis 2. Lexical Relations

3. Semantic Features A 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 [+ / -]. A 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 are those aspects of a linguistic unit, such as a morpheme, word, or sentence, that contribute to the meaning of that unit. Semantic properties are those aspects of a linguistic unit, such as a morpheme, word, or sentence, that contribute to the meaning of that unit.

4. Semantic Features Man is [+HUMAN], [+MALE], [+ADULT] Woman is [+HUMAN], [-MALE], [+ADULT] Boy is [+HUMAN], [+MALE], [-ADULT] Girl is [+HUMAN], [-MALE], [-ADULT]

5. Componential Analysis Componential analysis, also called feature analysis or contrast analysis, refers to the description of the meaning of words through structured sets of semantic features, which are given as “present”, “absent” or “indifferent with reference to feature”. Componential analysis, also called feature analysis or contrast analysis, refers to the description of the meaning of words through structured sets of semantic features, which are given as “present”, “absent” or “indifferent with reference to feature”.

6. Componential Analysis Componential analysis is a method typical of structural semantics which analyzes the structure of a word's meaning. Componential analysis is a method typical of structural semantics which analyzes the structure of a word's meaning. Thus, it reveals the culturally important features by which speakers of the language distinguish different words in the domain Thus, it reveals the culturally important features by which speakers of the language distinguish different words in the domain

7. Componential Analysis Example Man = [+ male], [+ mature] Man = [+ male], [+ mature] woman = [– male], [+ mature] woman = [– male], [+ mature] boy = [+ male], [– mature] boy = [+ male], [– mature] girl [– male] [– mature] girl [– male] [– mature] child [+/– male] [– mature]. child [+/– male] [– mature]. By this, we realize that the word girl can have three basic factors (or semantic properties): human, young, and female.

8. Binary Features In Componential Analysis, Binary Feature is used. In Componential Analysis, Binary Feature is used. A Binary Feature assumes both the [+] and [- ] Features. Girl, woman, sister, wife, queen [+ FEMALE ] Boy, man, brother, husband, king [+ MALE ] Child, person, sibling, spouse, monarch [sex not specified] (Lobner, 2002:133)

9. Binary Feature The features [FEMALE] and [MALE] are not just different but also complementary. We can replace them with one binary feature. Another example is: Woman [+FEMALE], [+ADULT], [+HUMAN] Bachelor [-FEMALE], [+ADULT], [+HUMAN], [-MARRIED] Spinster [+FEMALE], [+ADULT], [+HUMAN], [-MARRIED] Wife [+FEMALE], [+ADULT], [+HUMAN], [+MARRIED] So woman is [+/- MARRIED] (Saeed, 2002:261) (Saeed, 2002:261)

10. Lexical Relations Semantic features can be used to describe differences between Antonyms, Hyponymy, and Synonymy. Or Semantic Components might help us to define Lexical Relations.

11. Lexical Relations Hyponymy (Inclusion) Hyponymy (Inclusion) Hyponymy can be captured by binary features. Let’s examine Semantic Features (components) of Woman and Spinster. Woman [+FEMALE], [+ADULT], [+HUMAN] Spinster [+FEMALE], [+ADULT], [+HUMAN], [- MARRIED] We can see that the spinster is a hyponym of woman.

12. Lexical Relations And by comparing the sets of components we could define hyponymy as: And by comparing the sets of components we could define hyponymy as: A lexical item (P) can be defined as a hyponym of (Q), if all the features of (Q) are contained in the feature specification of (P). Woman is [+/- married], but Spinster is only [- married] (Saeed, 2002:260) (Saeed, 2002:260)

13. Lexical Relations Antonymy, or Incompatibility Antonymy, or Incompatibility By analyzing semantic components we also might be able to deal with some kinds of Antonymy or Incompatibility. E.g. we examine the words Bachelor, Spinster and Wife. Bachelor [MALE], [ADULT], [HUMAN], [-MARRIED]. Spinster [FEMALE], [ADULT], [HUMAN], [-MARRIED] Wife [FEMALE], [ADULT], [HUMAN], [+MARRIED]

14. Lexical Relations The words bachelor, spinster and wife are incompatible. The words bachelor, spinster and wife are incompatible. And the following definition can derived from a comparison of their semantic components: And the following definition can derived from a comparison of their semantic components: Lexical items P,Q,R are incompatible if they share a set of features but differ from each other by one or more contrasting features.

15. Lexical Relations Bachelor [MALE], [ADULT], [HUMAN], [-MARRIED]. Spinster [FEMALE], [ADULT], [HUMAN], [-MARRIED] Wife [FEMALE], [ADULT], [HUMAN], [+MARRIED] Thus spinster is incompatible with bachelor by contrast of gender specification; and with wife by the marital specification. Thus spinster is incompatible with bachelor by contrast of gender specification; and with wife by the marital specification. (Saeed, 2002:261) (Saeed, 2002:261)

16. Semantic Field Besides basic properties of semantics, semantic property is also sometimes used to describe the semantic components of a word, such as: Besides basic properties of semantics, semantic property is also sometimes used to describe the semantic components of a word, such as: Man assumes that the referent is human, male, and adult. and Man assumes that the referent is human, male, and adult. and Female is a common component of girl, woman, and actress. Female is a common component of girl, woman, and actress. In this sense, semantic properties are used to define the semantic field of a word or set of words. http://en.wikipedia.org/wiki/Semantic_feature http://en.wikipedia.org/wiki/Semantic_feature

17. Semantic Field A semantic field is a technical term in the discipline of linguistics to describe a set of words grouped by meaning in a certain way. A semantic field is a technical term in the discipline of linguistics to describe a set of words grouped by meaning in a certain way. Semantic Field is defined as the set of words covering a certain area in one language. It is often illustrated by the field of color terminology, e.g. green, blue and grey (Aitchison, 1992:82). Semantic Field is defined as the set of words covering a certain area in one language. It is often illustrated by the field of color terminology, e.g. green, blue and grey (Aitchison, 1992:82).

18. Semantic Field The words in a semantic field share a common semantic property. But, words in a semantic field are not synonymous, but are all used to talk about the same general. A kurdish example for Semantic Field may be: (طريان – فيغان – شيوةن – شةثوَر) (طوَر – كفن – كيَل - تةنط – تاريك)

19. Semantic Field The kinds of semantic fields vary from culture to culture. The kinds of semantic fields vary from culture to culture.
