 About me

Dr. Zhongyuan Wang currently is a Research Scientist at Facebook. Before Facebook, he was a Lead Researcher at Microsoft Research. He received his PhD (advisors are Haixun Wang and Ji-Rong Wen), master’s degree (advisor was Xiaofeng Meng) and bachelor's degree in computer science from Renmin University of China. Zhongyuan Wang won Wu Yuzhang Scholarship (Top-level Scholarship at Renmin University), Kwang-Hua Scholarship, and ACM SIGMOD07 Undergraduate Scholarship (one of the seven winners all over the world) in the university. After he graduated from RUC, he joined MSRA as a Research Software Development Engineer. Until now, Zhongyuan Wang has published several papers in the leading international conferences, such as VLDB, ICDE, etc. He is also the translator of the book “Windows Phone 7 Programming for Android and iOS Developers”, published in 2012. His research interests include knowledge base, web data mining, online advertising, machine learning and natural language processing.

Currently, Zhongyuan Wang takes charge of Probase project. He focuses on acquiring web tables, attributes, knowledge facts from more than 7 billion web documents in MS Cloud platform, addressing entities disambiguation/attributes synonyms in Probase, understanding web documents by reasoning over uncertain data, and building cool applications (such as short text understanding, ads matching, and query recommendation) upon on the knowledge base.

  • I lead two important projects in MSRA: Probase and Enterprise Dictionary, which were reviewed by Bill Gates, Harry Shum, Peter Lee, etc. The demo of Enterprise Dictionary was a candidate for MGX 2014.
  • I publish 10+ papers in top international conferences
  • I got the Best Paper Award in ICDE 2015
  • I have 4 US patents, and 1 Chinese patent
  • I'm the co-author/translator of 2 books: “Windows Phone 7 Programming for Android and iOS Developers”,  and “Web Data Management: Concepts and Techniques”
  • I won Wu Yuzhang Scholarship (Top-level Scholarship at Renmin University), and ACM SIGMOD07 Undergraduate Scholarship (one of the seven winners all over the world)

 Research Projects

  • Short Text Understanding /Conceptualization

The goal of this project is to provide better text understanding.

A large variety of applications need to handle short texts such as search queries, ads keywords, tweets, image captions, etc. Understanding short texts is a big challenge for machines. Unlike long texts and documents, for which we can use “bag of words” based statistical approaches to analyze, short texts do not contain enough information or statistical signals to make the analysis meaningful. Furthermore, short texts are usually not well-formed sentences. For example, queries submitted to search engines usually do not follow grammar rules. Consequently, approaches based on sentence structure analysis do not work well either. Human beings are good at deriving meaning from noisy, ambiguous, and sparse input. We understand short texts because knowledge in our mind enriches the input to produce meaning. Thus, in order for machines to understand short texts, we need to supply such knowledge to machines so that the gap between insufficient input and understanding can be bridged.

We have been continuously improving our conceptualization mechanism, which is at the core of our short text understanding services. We leverage the co-occurrence network to enhance sense disambiguation. We also generate the mappings between auxiliary words and concept clusters. These can help sense disambiguation using context auxiliary words.
