I am currently a PhD candidate in CICS of UMass Amherst working with Prof. James Allan in the Center for Intelligent Information Retrieval (CIIR). I work on different Information Retrieval, Natural Language Processing, and Machine Learning problems. Currently, I enjoy working on Cross-Lingual Information Retrieval (CLIR) which includes desigining search and recommendation models that are language-agnostic with the help of machine translation literature.
I obtained my MS degree in computer engineering from Bilkent University, Ankara, Turkey, 2016. I was fortunate to be a member of Bilkent Information Retrieval Group (BilIR) and work under the supervision of Prof. Fazli Can. I received my B.Sc. degree in Computer Engineering (Software Engineering) from Iran University of Science and Technology (IUST), Tehran, Iran, in 2013.
(August 2021) Three papers got accepted at CIKM 2021: (1) Cross-Market Product Recommendation (Pre-print, Dataset, Code) (2) Mixed Attention Transformer for Leveraging Word-Level Knowledge to Neural Cross-Lingual Information Retrieval (Pre-print) (3) Query-driven Segment Selection for Ranking Long Documents (Pre-print)
(March 2021) Our workshop proposal for cross-market recommendation is accepted at RecSys'21. See the Workshop Page
(October 2020) Our paper titled "100,000 Podcasts: A Large-Scale Spoken Document Corpus" is accpeted to COLING 2020 as a full paper. Congrats to colleagues @Spotify
(June 2020) I joined Spotify NLP research team @ Boston, MA for summer 2020 research internship program
(April 2020) Our paper titled "Training Effective Neural CLIR by Bridging the Translation Gap" is accpeted to SIGIR 2020 as a full paper. (Pre-print)
(Dec 2019) I passed PhD candidacy "with distinction"
Our paper titled "Unsupervised Concept Drift Detection with a Discriminative Classifier" is accepted as short paper to CIKM 2019.
Our paper titled "Simulating CLIR Translation Resource Scarcity using High-resource Languages" is accepted as full paper to ICTIR 2019 (Pre-print) (Dataset)
Our paper titled "Incorporating Hierarchical Domain Information to Disambiguate Very Short Queries" is accepted as short paper to ICTIR 2019 (Pre-print)(Dataset)
I started my research internship in AI team of Dataminr. NYC, Summer 2019.
Our paper titled "A Multi-Task Architecture on Relevance-based Neural Query Translation" is accepted as short paper in ACL 2019 (Pre-print)
Our paper titled "Less Is More: A Comprehensive Framework for the Number of Components of Ensemble Classifiers" is accepted as "Regular Paper" in the IEEE Transactions on Neural Networks and Learning Systems (TNNLS), The impact factor is 11.683. (Pre-print)
