Research

Areas (specific): Information Retrieval (IR) • Crowdsourcing & Human Computation (HCOMP) • Natural Language Processing (NLP)
Areas (general): Artificial Intelligence (AI) • Human-Computer Interation (HCI)

Overview: IR is the science behind search engines such as Google, Bing, & Yahoo. Crowdsourcing and human computation engage online workers to train or augment automated artificial intelligence algorithms. My IR research seeks to improve core search algorithms, reliably evaluate search systems, and to enable new forms of search. My HCOMP research seeks to optimize crowdsourced data collection (e.g., quality, cost, and speed), to expand the reach of crowdsourcing to tackle new problems, and to investigate broader socio-technical questions of how paid crowdsourcing is transforming digital work and the lives of workers engaged in it. At the intersection of IR and HComp, I develop crowdsourcing methods to better scale IR evaluation methodology while preserving its reliability. Both IR and HComp place people at the center of computing: system users in IR and online workers in HComp. I thus seek to orchestrate effective man-machine partnerships which creatively blend front-end HCI design with back-end AI modeling of people and their tasks. By capitalizing on the respective strengths of each party - man and machine - we can compensate for the other's limitations to create a whole greater than the sum of its parts. For example, IR systems can utilize front-end HCI design to empower searcher intuition and creativity, while back-end AI algorithms interpret ambiguous human queries, sift through vast information, and suggest potentially relevant results. In HCOMP, front-end HCI design can enable workers to more easily understand and complete tasks, while back-end AI modeling of workers and tasks enables principled optimization of data collection.

Biography. Matthew Lease received his Ph.D. in Computer Science from Brown University and his B.Sc. in Computer Science from the University of Washington. He received early career awards from the NSF, IMLS, and DARPA. Recent honors include Best Student Paper at the 2019 European Conference for Information Retrieval (ECIR) and Best Paper at the 2016 Association for the Advancement of Artificial Intelligence (AAAI) Human Computation and Crowdsourcing conference (HCOMP).
