Markov chain for Malayalam
Posted on June 8, 2019
| Santhosh Thottingal
I have been trying to generate a Markov chain for Malayalam content. A Markov chain is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event.(wikipedia). For natural language, it represents a probabilistic model of words- the probability that one word can come after another word. This model can be prepared by feeding large amount of text to system that learns the probabilities of each words.

Lexicon Curation for Mlmorph
Posted on May 26, 2019

One of the key components of Mlmorph is its lexicon. The lexicon contains the root words categorized as nouns, verbs, adjectives, adverbs etc. These are the components used with morphological rules to generate the vocabulary of Malayalam. I collected initial lexicon with about 100,000 words from various sources such as Wikipedia, CLDR and many targeted web crawls. One problem with such collected words is they often contains spelling mistakes. Secondly, classifying these words is not possible without the tedious task of a person going through each and every words.

This is an attempt to list down all forms of Malayalam word ചിരി(meaning: ☺️, smile, laugh). For those who are unfamiliar with Malayalam, the language is a highly inflectional Dravidian language. I am actively working on a morphology analyser(mlmorph) for the language as outlined in one of my previous blogpost.
