NLP Lab

Massive research project undertaken by Prof. Damir Cavar, under whom I am a volunteer research assistant, information regarding the same can be found here.
Gist of the whole is to create a NLP environment using various tools like Stanford CoreNLP, Spacy, etc. to extract information from corpus and augment a knowledge graph which can be parsed for easy extraction and validation of information under one umbrella project.
There are quite a few sub-projects in which I have been involved like
JSON-NLP Schema wherein we identified a common schema to gather outputs of the NLP tools in order to compare them and get the most accurate information and reduce the errors.
OpenIE (Open Information Extraction), which uses and extends the Yago database in order for us to validate the information we gather from various corpus, and then extend the database. We utilize Neo4J to create a small graph databse of the information extracted for comparision with Yago and MongoDB is utilized to load the data from Microsoft Concept Graph and DbPedia in order to identify the most relevant hypernym for the entity extracted e.g. Apple is a company while apple is a fruit.
HOOSIER (Hoosier Semantic Information ExtractoR), which will extend OpenIE and utilize network analysis tool like SNAP in order to analyze the sematic relation between entities.


Projects

  • Analysis of Bitcoin Blockchain
    Researched the Bitcoin Blockchain w.r.t. functionality like block, nonce, mining, in order to demonstrate how it actually works also implemented certail aspects of the same. The entire was presented to a group of peers in order to showcase the capabilities and drawbacks of using blockchain and to bust some myths.

  • Pichu
    Implemented a restricted version of chess and tried to maximize winning chance of player we represent by implementing the min-max algorithm to run on the statespaces for each play.

  • Parts of Speech Tagging
    Trained models to showcase the difference between Naive Bayes, Variable Elimination and and Viterbi Algorithm and analyzed the model performance by training it to tad the parts of speech of a given corpus. Naive Bayes achieved 78%, Variable Elimination achieved 89% and Viterbi achieved 93% accuracy.

  • Spooky Author Classification
    Trained models based on Naive Bayes, Viterbi Algorithm and NN on a corpus of 3 authors and then classified test sentences for each to showcase difference and accuracy of all 3 implementations. WHile implementing Naive Bayes I had an inkling that the problem looked like a HMM and so attempted Viterbi as well. Naive Bayes achieved 89%, Viterbi achieved 74% and NN achieved 96% accuracy.

  • Tweet Extraction and Classification
    Extracted tweets associated with cat, dog and both and extracted a portion of the same for testing the implementation and used the rest to train models implemented using scikit learn package, implemented Naive Bayes (80-82%), SVM(44-53%), NN (90-95%), KNN 1 Neighbor(86-92%), KNN 5 Neighbor (89-92%) and KNN 5 Neighbor Weighted (90-93%) for 1500 and 4000 tweets respectively.
