The Information Retrieval and Data Science Group’s (I.R.D.S.) mission is to research and develop new methodology and open source software to analyze, ingest, process, and manage Big Data and to turn it into information. We contribute to the world’s largest and most often downloaded open source software projects, we apply tried and true techniques including content detection and analysis, crawling, deduplication, similarity, named entity recognition, construction of inverted indices, query analysis, search, relevancy and ranking, interactive query analysis, and management of large data sets. We have expertise in data collection, working with NASA, DARPA, DHS, NIH across a number of domains, Earth Science, Planetary Science, Astronomy, defense, and private industry.
Dr. Chris Mattmann is the Director of the IRDS Group at USC and an Adjunct Research ("Full") Professor and has taught at the University since 2008, and been a student at USC since 1998. Mattmann was instrumental in establishing USC as a powerhouse in data science building a diverse portfolio of awards from many sponsors. Mattmann has advised 3 Postdocs, and mentored hundreds of masters and dozens of undergraduate students. In addition to his roles at USC, Mattmann is also the Chief Data and Artificial Intelligence Officer (CDAIO) at UCLA, the first such position in the UC system. He collaborates with key stakeholders to develop the strategy and roadmap for data and artificial intelligence (AI) innovations. Before UCLA, Mattmann was the Division Manager of the Artificial Intelligence, Analytics and Innovative Development Organization at NASA JPL and was the Chief Technology and Innovation Officer. Mattmann has a proven track record of delivering large enterprise implementations that fundamentally changed the way the world searches, clicks on, organizes, and transacts with data. He is experienced leading executive committees, advising the C-Suite, chairing governance boards and in making organization’s data more valuable.
Dr. Jeffrey Miller is currently an Associate Professor of Engineering Practice in the Computer Science department at the University of Southern California. Prior to that, he was an Assistant and Associate Professor in the Computer Engineering department at the University of Alaska Anchorage for six years and an Adjunct Professor in the Computer Science department at California State University, Los Angeles for five years. Dr. Miller’s research interests include vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication, ethical issues related to driverless vehicles, and Computer Science education (K12, undergraduate, and graduate). He has given talks for the National Academy of Engineers and other organizations related to ethics in driverless vehicles, and he has a passion for K12 STEM education. Jeff helps IRDS by running our Undergraduate Capstone class and has helped supervise several IRDS projects that have advanced machine learning, search, and AI.
Yao-Yi Chiang is an Associate Professor (Research) in Spatial Sciences, the Director of the Spatial Computing Laboratory at the Spatial Sciences Institute, and the Associate Director of the NSF's Integrated Media Systems Center (IMSC) at the University of Southern California (USC). Dr. Chiang received his Ph.D. degree in Computer Science from the University of Southern California; his bachelor’s degree in information management from the National Taiwan University. His general area of research is information integration and data mining with a focus on spatiotemporal data and their applications. Dr. Chiang is also an expert on digital map processing and geospatial information system (GIS). His research interests further include computer vision, image processing, and semantic web. Dr. Chiang develops computer algorithms and intelligent systems that discover, collect, fuse, and analyze data from heterogeneous sources to solve real-world problems. Before USC, Dr. Chiang worked as a research scientist for Geosemble Technologies and Fetch Technologies in California. Geosemble Technologies was founded based on a patent on geospatial data fusion techniques, and he was a co-inventor. Yao-Yi contributes by supervising and mentoring Directed Research projects for IRDS.
