Ontology-Guided Query Expansion for Biomedical Document Retrieval using Large Language Models
Zabir Al Nazi, Vagelis Hristidis, Aaron Lawson McLean +2
Effective Question Answering (QA) on large biomedical document collections requires effective document retrieval techniques. The latter remains a challenging task due to the domain…
Progressive Query Expansion for Retrieval Over Cost-constrained Data Sources
Muhammad Shihab Rashid, Jannat Ara Meem, Yue Dong +1
Query expansion has been employed for a long time to improve the accuracy of query retrievers. Earlier works relied on pseudo-relevance feedback (PRF) techniques, which augment a q…
NORMY: Non-Uniform History Modeling for Open Retrieval Conversational Question Answering
Muhammad Shihab Rashid, Jannat Ara Meem, Vagelis Hristidis
Open Retrieval Conversational Question Answering (OrConvQA) answers a question given a conversation as context and a document collection. A typical OrConvQA pipeline consists of th…
PAT-Questions: A Self-Updating Benchmark for Present-Anchored Temporal Question-Answering
Jannat Ara Meem, Muhammad Shihab Rashid, Yue Dong +1
Existing work on Temporal Question Answering (TQA) has predominantly focused on questions anchored to specific timestamps or events (e.g. "Who was the US president in 1970?"). Litt…
EcoRank: Budget-Constrained Text Re-ranking Using Large Language Models
Muhammad Shihab Rashid, Jannat Ara Meem, Yue Dong +1
Large Language Models (LLMs) have achieved state-of-the-art performance in text re-ranking. This process includes queries and candidate passages in the prompts, utilizing pointwise…
Generalized Zero-shot Intent Detection via Commonsense Knowledge
A. B. Siddique, Fuad Jamour, Luxun Xu +1
Identifying user intents from natural language utterances is a crucial step in conversational systems that has been extensively studied as a supervised classification problem. Howe…
Linguistically-Enriched and Context-Aware Zero-shot Slot Filling
A. B. Siddique, Fuad Jamour, Vagelis Hristidis
Slot filling is identifying contiguous spans of words in an utterance that correspond to certain parameters (i.e., slots) of a user request/query. Slot filling is one of the most i…
Unsupervised Paraphrasing via Deep Reinforcement Learning
A. B. Siddique, Samet Oymak, Vagelis Hristidis
Paraphrasing is expressing the meaning of an input sentence in different wording while maintaining fluency (i.e., grammatical and syntactical correctness). Most existing work on pa…
App-Aware Response Synthesis for User Reviews
Umar Farooq, A. B. Siddique, Fuad Jamour +2
Responding to user reviews promptly and satisfactorily improves application ratings, which is key to application popularity and success. The proliferation of such reviews makes it…
Top-K Product Design Based on Collaborative Tagging Data
Mahashweta Das, Gautam Das, Vagelis Hristidis
The widespread use and popularity of collaborative content sites (e.g., IMDB, Amazon, Yelp, etc.) has created rich resources for users to consult in order to make purchasing decisi…
