Hi  Nadana Ravishankar,

There are prepositions, negation, questions, adverbs, and pronouns as important rules in Tamil. As I believe that you just follow the structure of the language is enough since you are going to type limited number of letters.

Hi,

I don't think anyone can say how many grammar rules there are in any given language. Theoretically, whether you are a generativist grammarian or just an NLP practitioner, the assumption is that there is a finite number or grammatical rules (though we don't know how many) capable of analyzing or generating an infinite set of well-formed sentences.

In practice, though, it all depends on a lot of variables. I think the most important one is the application. If you're trying to achieve fine-grained syntactic representations (for example, if you're building a Tamil Treebank, or if you're working on deep parsing for Machine Translation), then you'll probably need rather complex syntactic formalisms (by descending order of complexity: HPSG, TAG, LFG, PCFG), and you'll have to manage quite a few rules, and probably end up writing a PhD in the process. On the other hand, if you're "just" trying to spot specific words or patterns, regular expressions or finite state transducers will generally do the trick. Now, if Tamil allows for complex morphological operations such as can be found in semitic languages (i.e. 3-consonantic roots, eg. k-t-b --> kitab, kataba, mektub...) or if word boundaries are not that clear (as in Arabic, or worse Thai), then you'll probably have to use weighted finite-state transducers, just for spotting words. So even spotting patterns made of specific words might not be that easy.

Could you elaborate a little on the kind of application you're working on?

I am also interested in this, waiting for more answers.
