USE OF CORPUS TO INVESTIGATE AND
DEVELOP LEXICAL KNOWLEDGE

3. CONTINUE…
• Use of corpus to investigate and develop lexical knowledge through phrase,
phraseology, collocation, colligation ,polysymy, word formation ,lexical sets
etc.

4. WHAT IS LEXIS
• According to oxford dictionary the level of language consisting of
vocabulary , as opposed to grammar or syntax: the distinction between
grammar and lexis.
• According to Collins English dictionary the totality of vocabulary items in a
language, including all forms having lexical meaning and grammatical
function from the Greek lexis words.

5. CONTINUE….
• Linguistic is the scientific study of language.
• According to ‘Sinclair’ ‘one does not study all botany by
making artificial flowers’.
• According to ‘Trudgill’ Trudgill is even harsher in his criticism
of those who do not base their descriptions on actual
language use. in the final analysis if linguistic is not about
language as it is opposed actually being spoken or written
by human beings, then it is about nothing at all.

6. WHAT IS CORPUS?
• Corpus is not just any collection of text, a corpus is a collection of naturally
occurring language text chosen to characterize a state or variety of a
language. in other words corpus is designed and complied based on corpus
design principles. another feature which is fundamental to corpus linguistic is
that a corpus is ‘machine readable’.

7. LIMITATIONS OF CORPUS
• Corpora can tell us whether something is frequent, or not, but they are not
able to tell us if something is possible in a language.
• Corpora can only show us what they contain.
• Corpora can give us evidence but the user must then interpret this
information.
• Corpora contain examples of language outside of divorced from their
original ‘visual and social context’.

8. CONTINUE….
• It’s a healthy, vibrant discipline’.
• The key to its success remains the same basic method.
• Large quantities of ‘raw’ text are opposed directly in order to present the
researcher with objective evidence.

9. CORPUS-DRIVEN AND CORPUS-BASED
APPROACHES
• Corpus-based approach is ‘deductive’ because reasoning works from the
more general to the more specific, which is a ‘top down’ approach. The
researcher begins with a theory about a topic of interest and then narrows
that down into more specific hypothesis that can be tested using a corpus.
• Corpus-driven approach is ‘inductive’ Inductive reasoning works from
specific observation to broader generalizations and theories, and therefore
a bottom-up approach. the researcher begins with specific observations
and measures in order to identify patterns and regularities.

10. PHRASE
• In everyday speech, a phrase may refer to any group of words. In linguistics,
a phrase is a group of words that form a constituent and so function as a
single unit in the syntax of a sentence.
• Examples
• in the big hall

considering the sum of its parts.
