• Research Engineer

  searchme

  (Privately Held; Internet industry)

  July 2008 — July 2009 (1 year 1 month)

  Searchme was a search engine startup. As a research engineer, I created new features and products to improve our engine, with particular emphasis on relevance and web spam detection. I worked primarily with perl, python, hadoop and sql. Searchme shut down in July 2009.
  
  Some of the projects I did:
  
  -Designed and built a system for automatically assessing the general quality of a web document. Led to 5.7% improvement in DCG (discounted cumulative gain).
  -Experiments in feature selection, in order to maximize DCG at lowest cost. Led to 2% improvement in DCG.
  -Data mining in various logs for new feature generation. These features were added to our production ranking system.
  -Designed and built a webspam detection system that is production live. I worked on all aspects of this project from feature development, training data generation, feature and dataset analysis, and model evaluation.
  -Multimedia blending of results: Created a machine learned model that serves relevant mixed media content in the search results when the query is appropriate for showing media; built automated system for collecting media content from various sources so it could be added to our index and served as a result in our UI; feature selection and generation to ensure relevant media results rank correctly, and blend properly with non-media results; set up a production-like environment for evalulation of the model before launching live.
