Data Science Portfolio

Data Mining: Bing Search Engine

  • Improved Bing's search results by finding and normalizing business name synonyms during my data analyst internship at Microsoft
  • Before my work, searching for “7 11” returned fewer results than “7-Eleven”. After my work, both queries returned the same number of results.
  • Normalized 38,910 distinct businesses and propagated website information between 49,145 distinct businesses

Skills: Data mining Data analysis Natural language processing Project documentation

Tools: SQL Regular expressions Cosmos
