Jiafeng Guo is currently a Professor in Institute of Computing Technology, Chinese Academy of Sciences, and University of Chinese Academy of Sciences. He received his B.E. in Computer Science and Technology from the University of Science and Technology of China, Hefei, China, in 2004 and earned his Ph.D. in Computer Software and Theory from the University of Chinese Academy of Sciences, Beijing, China, in 2009.

Dr. Guo has worked on a number of topics related to Web search and data mining, including query representation and understanding, learning to rank, and topic modeling. His current research is focused on representation learning and deep models for information retrieval and information filtering. He has won the Best Paper Award in ACM CIKM (2011) and Best Student Paper Award in ACM SIGIR (2012).

MatchingZoom is a toolkit for text matching. It was developed with a focus on facilitate the designing, comparing and sharing of deep text matching models. The architecture of the MatchZoo toolit is depicited in Figure. There are three major modules in the toolkit, namely data preparation, model construction, training and evaluation, respectively. These three modules are actually organized as a pipeline of data flow.

Social Scholar (http://soscholar.com)

A vertical social network platform for academia. The system aims to introduce collaboration into academic search, mining and analysis tasks. Supported by CAS-ICT innovation project.

Academic Universe (http://soscholar.com/universe)

A platform for fast exploring linked academic objects. The system provides users with a single-page view of multiple academic objects, and allows users to easily explore the academic data by filtering different aspects.

The Academic Benchmark is designed to facilitate research in computer science (CS). The major purpose is to change the situation in CS where most published methods are difficult to compare with due to the lack of public dataset, open codes, or clear experimental settings. Therefore, in this website, we not only report the performances of state-of-the-art algorithms in different domains, but also collect the corresponding datasets, codes, and scripts that can make the experimental results reproducible. When developing new methods in these domain, researchers can simply take-away and compare with all the available baseline methods. In this way, we can help researchers spend less time on duplicated efforts, and focus more on new ideas.
