iTA: A Digital Teaching Assistant

Topics: Intelligent Tutoring Systems; Mentoring and Tutoring

In Proceedings of the 13th International Conference on Computer Supported Education - Volume 2: CSEDU, 274-281, 2021

Authors: Vishnu Dutt Duggirala ; Rhys Sean Butler and Farnoush Banaei-Kashani

Affiliation: Department of Computer Science and Engineering, University of Colorado Denver, U.S.A.

Keyword(s): Machine Reading Comprehension, Question-answering.

Abstract: Designed and implemented a question-answering chatbot, dubbed iTA (intelligent Teaching Assistant), which can provide detailed answers to questions by effectively identifying the most relevant answers in “long” text sources (documents or textbooks). iTA answers questions by implementing a two-stage procedure. First, the topmost relevant paragraphs are identified in the selected text source using a retrieval-based approach and scores for the retrieved paragraphs are computed. Second, using a generative model, extracted the relevant content from the top-ranked paragraph to generate the answer. Our results show that iTA is well suited to generate meaningful answers for questions posed by students.
