My research helps people better work with search systems and text analytics. I apply a combination of information retrieval, data/text mining, and HCI methods to study search engines, conversational systems (chatbots), exploratory text analytics, and other techniques for understanding large-scale text data.

Jiepu Jiang is an Assistant Professor of Computer Science at Virginia Tech (started in August 2018). He directs the Human AI Technology (HAT) lab and is affiliated with the Digital Library Research Lab (DLRL) and the Discovery Analytics Center (DAC). He has regularly published and served in top conferences & journals such as SIGIR, WWW, WSDM, CIKM, and JASIST. His research has received the best student paper award in CHIIR 2017 (the ACM SIGIR Conference on Human Information Interaction & Retrieval). He holds bachelor's degrees and a master's degree from Wuhan University, a Ph.D. in Library & Information Science from the University of Pittsburgh, and is finishing up another Ph.D. in Computer Science from the University of Massachusetts Amherst.

My group has two Ph.D. openings for Fall 2019 admissions. Please send me an email with your CV if you are interested. Students will work on highly interdisciplinary research topics connecting human and information retrieval, text analytics, and AI, such as:

  • Explainable Information Retrieval: making search/retrieval techniques more understandable to end users and experts
  • Exploratory Text Analytics: addressing ad hoc text mining problems in an interactive mode with minimal human inputs
  • Human-AI Collaboration Techniques for IR & text mining applications
