CAREER: Human-Computer Cooperation for Word-by-Word Question Answering

Categories: Research, Chatbots & Assistants, Education | Pricing: Free | Official Website ↗

A research project investigating human-computer collaboration for efficient word-by-word question answering using AI and natural language processing.

This CAREER project, funded by the National Science Foundation, explores how humans and computers can effectively collaborate to answer questions. It focuses on leveraging the complementary strengths of both: human commonsense and language understanding, and computer's factual recall and retrieval. A core aspect of the research is word-by-word question answering, which aims to optimize information usage for both human and computer participants. The project develops new representations of entities using medium-dimensional embeddings to encode relationships between them, enabling the system to answer complex questions. The effectiveness of these representations is validated through traditional question answering evaluations and interactive experiments involving human collaboration. Beyond training computers, the research also uses opponent modeling and reinforcement learning to help improve human question-answering skills. The project includes an outreach program to engage high school and college students in interactive question-answering competitions.
