analysis

Слайд 4The process of scientific investigation may be subdivided into several stages:
1.

observation (the collection of data)
2. classification (orderly arrangement of the data obtained through observation)


Слайд 5Example: English nouns
-er is added to verbal stems (speak + -er),

noun stems (village + -er),
the same morpheme in mother, father. But they haven’t a suffix


-er can be found in derived and non-derived words



Слайд 6
3. generalisation (the formulation of a hypothesis, rule, or law)




Слайд 7Example: The rule:
derived nouns in -er may

have either verbal or noun stems.

The suffix -er in combination with adjectival or adverbial stems cannot form nouns (bigger, longer are not nouns).



Слайд 8
4. verification (to seek evidence of the correctness of the generalizations

that are the result of the inquires)

Слайд 9Various methods of lexicological research are used for classification, generalization and

verification:

1. Contrastive analysis.
2. Statistical methods of analysis.
3. Immediate Constituents analysis.
4. Distributional analysis.
5. Transformational analysis.
6. Componential analysis.


Слайд 10
The selection of this or that particular method largely

depends on the goal set before the investigator.

Слайд 11
Contrastive analysis



Слайд 12
Comparative linguistics investigates those elements and processes despite their surface diversity

that all languages have in common.

Contrastive linguistics attempts to find out similarities and differences in both related and non-related languages.


Слайд 13The aim of the contrastive analysis:
a detailed comparison of the

structure of a native and a target language

Слайд 14Contrastive analysis can be carried out at three linguistic levels:
phonology


grammar (morphology and syntax)
lexis (vocabulary)

Слайд 15
Contrastive analysis is the basis of teaching foreign languages:

it helps to foresee and prevent recurrent mistakes caused by the interference of the learner‘s mother tongue.

Слайд 16
новости, деньги, волосы plural
news, money,

hair singular




Слайд 17
Contrastive analysis is generally applied to reveal the

features of sameness and difference in the lexical meaning and the semantic structure of correlated words in different languages.

Слайд 18
Watch, clock and часы
Head: the head of a person, bed or

match; in Russian different words have to be used: голова человека, изголовье кровати, сторона монеты


Слайд 19
Statistical methods of analysis


Слайд 20The aim of the statistical analysis:
the quantitative evaluation of the material

(different structural types of words, affixes, vocabularies of great writers, etc.)
the selection of vocabulary items of a foreign language for teaching purposes

Слайд 21
Statistical regularities can be observed only if the phenomena

under analysis are sufficiently numerous.

Слайд 22
Immediate Constituents analysis


Слайд 23
The theory of Immediate Constituents is based on the

idea that combinations of units are usually structured into hierarchial sets of binary constructions (Immediate Constituents.

Слайд 24The aim of the Immediate Constituents analysis:
1. to find out the

morphemic structure of lexical units

Слайд 25Friendliness:
1. is divided into the component friendly-, occurring in such words

as friendly, friendly-looking, and the component ness- as in dark-ness, happy-ness.
2. is divided into friend- and -ly which are ultimate constituents (cannot be divided into smaller meaningful units).

Слайд 26The aim of the Immediate Constituents analysis:
2. to determine the ways

in which lexical units are relevantly related to one another

Слайд 27a black dress in severe style
a black

dress | in severe style

a + black + dress|in + severe + style










Слайд 28 Immediate Constituents analysis depends on the meaning of the whole complex:

fat major’s wife ?

fat major’s | wife

fat | major’s wife


Слайд 29
Distributional Analysis


Слайд 30Distribution:
the position which linguistic units may occupy in the flow of

speech, or the co-occurrence of units of the same level: words to words, morpheme to morphemes

Слайд 31The aim of the distributional analysis:
the investigation of sameness / difference

of meaning of words and word-groups
the analysis of word-formation.

Слайд 32
The word has different meanings in different patterns:
to treat

smb kindly (treat + N + Adv) – to behave towards;
to treat smb to ice-cream (treat + N + to + N) – to supply with smth at one’s own expense.

Слайд 33The boy__________ home.
the missing word is easily identified as

a verb (came, went, goes, etc.), but not as an adverb or a noun, or an adjective

Слайд 34
Transformational Analysis


Слайд 35Transformational analysis:
repatterning (reorganization) of identical distributional structures in order to

discover difference or sameness of their meaning.

Слайд 36Example of transformation:
his work is excellent –
his excellent work –


the excellence of his work –
he works excellently

Слайд 37The aim of the transformational analysis:
to investigate polysemantic patterns (e.g. compounds

which have the same pattern (n + n) may have different lexical meanings: dogfight – a fight between dogs; dogcart – a cart drawn by dogs)

Слайд 38
Componential Analysis


Слайд 39
In the componential analysis linguists proceed from the assumption

that the denotational component of word meaning can be seen as a complex cluster of smaller units - semantic components, or semes organized in a componential structure.

Слайд 40
man can be described as [+HUMAN] [+ADULT] [+MALE]
boy as [+HUMAN] [–ADULT]

[+MALE]
woman as [+HUMAN] [+ADULT] and
[–MALE]
girl as [+HUMAN] [–ADULT] and
[– MALE].


Слайд 41
It helps to find out which of the meanings

should be represented first of all in the dictionaries of different types and how the words should be combined in order to make your speech sensible.
