This repository exhibits the power and the importance of domain knowledge(in this case, it's English grammar) in building good features and a good model. However, if you want to solve this problem today, my recommendation would be train a Bi-directional LSTM model - Primarily, because of the availability of ready made, free and massive amount of training data set for this problem(Pick up the content from any standard book, novel, news paper :-) ).
Each code snippet tries to tell a story from the Text Mining world.

Simple implementation of Hidden Markov Model for discrete outcomes/observations in Python. It contains implementation of 1. Forward algorithm 2. Viterbi Algorithm and 3. Forward/Backward i.e. Baum-Welch Algorithm.
A python toolbox for gaining geometric insights into high-dimensional data
At Karza Technologies, we are creating one of the most comprehensive and AI based digital due-diligence platform that helps financial institutes realise the possibilities of AI at each stage of decisioning viz on-boarding & KYC, due diligence, monitoring, skip tracing and recoveries. On top of thousands of publicly available data points, we are applying state-of-the-art algorithms/techniques in Fraud analytics, Semi-supervised Graph Algorithms, Computer Vision and NLP etc. to help financial institutes combat unconventional problems as diverse as capturing irregularities in Indian names & addresses, automate document worflows on virtually any kind of document and automated filtering of applications basis Risk Score. This Repository contains details pertaining to the Open-Paper Recruitment at Karza for the position of a Data Scientist.

This repository contains my experiments with RAKE and its variants. RAKE is one of the most popular unsupervised approach for automatically extracting key-phrases/keywords from an unstructured data source like reviews, news, articles, documents etc.
Sentiment Analysis Using Python NLTK. This Repository contains 3 models for Sentiment Analysis: 1. Naive Bayes 2. MaxEnt Model 3. SVM Model
This repository holds an implementation of Discrete Hidden Markov Model which is trained and tuned to work for the sequence prediction challenge (SPiCe). Parameter tuning of this simple HMM implementation got me top 10 in the global ranking of the Sequence Prediction Challenge(SPiCe).
