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. [Read More]

 Posted on May 26, 2019  |  Santhosh Thottingal

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. [Read More]

Malayalam Named Entity Recognition using morphology analyser

 Posted on March 10, 2019  |  Santhosh Thottingal

Named Entity Recognition, a task of identifying and classifying real world objects such as persons, places, organizations from a given text is a well known NLP problem. For Malayalam, there were several research papers published on this topic, but none are functional or reproducible research. The morphological characteristics of Malayalam has been always a challenge to solve this problem. When the named entities appear in an inflected or agglutinated complex word, the first step is to analyse such words and arrive at the root words. [Read More]
