Research Interest

  • Web search, Data Mining, Computing for Development, Computers in Education, Computational Sustainability


Education

  • PhD (Sep 2010- present): Department of Computer Science, New York University, USA .

  • MS (2008): Department of Computer Science and Engineering, Indian Institute of Technology, Kharagpur, INDIA. [MS Thesis: Shikshak: A Framework for an Intelligent Tutoring System]

  • B.Tech (2004): Department of Computer Science & Engineering, University of Kalyani, INDIA


Projects

  • Drought characterization and Prediction from Online Media: From a corpus of news articles, identification of occurrences and magnitude of drought in different locations and based on past drought cases, characterizing the causes and effects of drought in a particular location. Using these past trends, a model is being trained to predict drought in a particular location given recent news articles from that location. Methodology is based on spatial- temporal relationship analysis, topic modeling and event extraction from the news documents.
  • Location-Specific Summarization of Climatic and Agricultural Trends: Mining information from the web to collect data about agriculture, climate change, identify and predict the presence of different problems in these areas in a particular location.
  • Structured summarization of unstructured text: In some cases, users search a website where the website text is in an unstructured form. However, the user query is in a structured format. Changing the backend text into a structured form can greatly improve the search quality, search speed and the presentation of the results. This project is aimed to extract key features from such texts and prepare a structured summary of the entire content, taking Craigslist ads as a case.
