Getting Better Dialogue Context for Knowledge Identification by Leveraging Document-level Topic Shift

no code implementations SIGDIAL (ACL) 2022 Nhat Tran, Diane Litman

To build a goal-oriented dialogue system that can generate responses given a knowledge base, identifying the relevant pieces of information to be grounded in is vital.

Multi-task Learning in Argument Mining for Persuasive Online Discussions

no code implementations EMNLP (ArgMining) 2021 Nhat Tran, Diane Litman

We utilize multi-task learning to improve argument mining in persuasive online discussions, in which both micro-level and macro-level argumentation must be taken into consideration.

Enhancing Knowledge Retrieval with Topic Modeling for Knowledge-Grounded Dialogue

1 code implementation7 May 2024 Nhat Tran, Diane Litman

In this work, we propose an approach that utilizes topic modeling on the knowledge base to further improve retrieval accuracy and as a result, improve response generation.

Utilizing Natural Language Processing for Automated Assessment of Classroom Discussion

no code implementations21 Jun 2023 Nhat Tran, Benjamin Pierce, Diane Litman, Richard Correnti, Lindsay Clare Matsumura

Rigorous and interactive class discussions that support students to engage in high-level thinking and reasoning are essential to learning and are a central component of most teaching interventions.

Layer-stacked Attention for Heterogeneous Network Embedding

no code implementations17 Sep 2020 Nhat Tran, Jean Gao

Additionally, by successively stacking layer representations, the learned node embedding offers a more interpretable aggregation scheme for nodes of different types at different neighborhood ranges.

Network Representation of Large-Scale Heterogeneous RNA Sequences with Integration of Diverse Multi-omics, Interactions, and Annotations Data

no code implementations17 Jun 2019 Nhat Tran, Jean Gao

We proposed a novel deep learning-based framework, rna2rna, which learns from RNA sequences to produce a low-dimensional embedding that preserves the proximities in both the interactions topology and the functional affinity topology.
