David Carmel (born 1955) is an Israeli computer scientist specializing in information retrieval (IR).[1] He is a Scientist at the Technology Innovation Institute (TII) in Haifa, where his research focuses on IR and generative AI.[2]
He is also a part-time Research Fellow at the Technion,[3] Israel Institute of Technology. Carmel is an Association for Computing Machinery (ACM) Distinguished Member since 2016[4] and was elected in 2025 to the ACM SIGIR Academy.[5]
Early years
David Carmel was born in 1955 in Kibbutz Beit HaShita, Israel. He is the eldest son of Dan, who worked at the Beit HaShita Metal Industries[6] and Elka, who worked as a seamstress.[7]
Education
Carmel received a B.Sc. in mathematics and physics from the Haifa University, Israel in 1982. After working for over a decade as a mathematics teacher in Beit HaShita High School,[8] he pursued graduate studies in computer science at the Technion,[9] Israel Institute of Technology. He completed his Ph.D. in 1997 under the supervision of Prof. Shaul Markovitch, specializing in artificial intelligence.[10]
Career
Upon graduating, Carmel joined IBM Haifa Research Labs, working on the Juru information retrieval system; there he led the team that achieved the best precision@10 score at the TREC conference in the “ad-hoc” Web search track in 2001.[11] Another area he explored was efficiency, first with static index pruning, published with co-authors at SIGIR 2001,[12] and, two years later, with dynamic pruning, embodied in the now well-known WAND algorithm, published at CIKM 2003, jointly with Andrei Broder and others.[13] The WAND algorithm was extended later by many other researchers in the community.[14] Carmel contributed to the development of the XML Fragments query language, which adopted a classical IR approach for XML search by embedding the XML query and the XML fragments into the same search space.[15] The XML search engine relying on XML Fragments that achieved top results at the INEX competition over the years 2002-2006.[16]
Carmel then looked at another key challenge in IR around “difficult queries”. His paper on “Learning to Estimate the Query Difficulty”, together with Elad Yom-Tov and others, earned the best paper award at SIGIR 2005.[17] [18]
Carmel was a contributor to IBM Watson project, which competed against human champions on the television quiz show Jeopardy!.[19][20][21]
He joined Yahoo Research in 2013 and contributed to multiple research efforts, in particular, around reinventing Web Mail Search, devising new ranking algorithms[22][23] that were deployed in Yahoo mail, serving millions of users, and helped revive a dormant area of research.[24][25]
Dr. Carmel is listed as the inventor on dozens of patents registered in the United States and internationally, granted during his time at IBM and Yahoo. [26]
Between 2017 and March 2024, Carmel served as a Principal Applied Scientist at Amazon.[27] There he started investigating yet another field of research around voice product search/question answering with Alexa (Amazon’s voice assistant). The results of his research were deployed to hundreds of millions of Alexa’s customers and led to several publications.[28][29][30][31]
Since 2024, he has been serving as a Distinguished Researcher at the Technology Innovation Institute (TII), focusing on Retrieval Augmented Generation (RAG), thus combining his early days’ love for AI and his world-wide expertise in search.[32]
Teaching and Academia
Throughout his industrial career, Carmel maintained ties with academia. He was a part-time lecturer for several years in courses on artificial intelligence and information retrieval in the Department of Computer Science at the University of Haifa.[33] As of 2024, he was appointed as a Research Fellow at the Technion, in the Faculty of Data and Decision Sciences.[3]
Publications
Dr. Carmel has published over 100 papers [34] in leading international journals and conferences, including SIGIR, WWW, WSDM, and CIKM. Among his notable publications, he co-authored the paper “Learning to Estimate Query Difficulty”, which won the Best Paper Award at SIGIR 2005.[35]
Carmel jointly with one of his coauthors, Dr Elad Yom-Tov then extended this work and published a book entitled Estimating the Query Difficulty for Information Retrieval, which was published by Morgan & Claypool in 2010.[36]
