What are different aspects of a Text Analysis or Generation?
Syntax, structure of sentences (role of the words), Grammar (set of rules, principles and processes)
Semantics, meaning of words and combination of words (to meaningful phrases and sentences)
- done by mapping syntactic structures and objects in the task domain
Morphology, form construction of words
- Stem – the smallest meaningful unit for a word – untouchable (from untouchable-s)
- Root – does not have a prefix or a suffix before or after the word (Touch (from Un- touch-able-s))
- Base is any form to which affixes can be added which change the meaning of the word (book – booking)
Lexicon
- the study of words, their nature and meaning
- a collection of information about the words
- usually structured as a collection of lexical entries ( like ”run" N V Adj, Adv).
- what form the verb takes, e.g., present participle (the form base +ing), or presence, past tense, future tense
Pragmatics – situation / context analysis
- interpreting what it actually meant.
- involves deriving those aspects of language, which require real world knowledge
