Long-form Question Answering: An Iterative Planning-Retrieval-Generation Approach

no code implementations15 Nov 2023 Pritom Saha Akash, Kashob Kumar Roy, Lucian Popa, Kevin Chen-Chuan Chang

From an extensive experiment on both an open domain and a technical domain QA dataset, we find that our model outperforms the state-of-the-art models on various textual and factual metrics for the LFQA task.

Long Form Question Answering Retrieval

Let the Pretrained Language Models "Imagine" for Short Texts Topic Modeling

no code implementations24 Oct 2023 Pritom Saha Akash, Jie Huang, Kevin Chen-Chuan Chang

Besides, we provide a simple solution extending a neural topic model to reduce the effect of noisy out-of-topics text generation from PLMs.

Text Generation Topic Models

TopicAdapt- An Inter-Corpora Topics Adaptation Approach

no code implementations8 Oct 2023 Pritom Saha Akash, Trisha Das, Kevin Chen-Chuan Chang

Topic models are popular statistical tools for detecting latent semantic topics in a text corpus.

Topic Models

Unsupervised Open-domain Keyphrase Generation

no code implementations19 Jun 2023 Lam Thanh Do, Pritom Saha Akash, Kevin Chen-Chuan Chang

To solve this problem, we propose a seq2seq model that consists of two modules, namely \textit{phraseness} and \textit{informativeness} module, both of which can be built in an unsupervised and open-domain fashion.

Informativeness Keyphrase Generation

Coordinated Topic Modeling

no code implementations16 Oct 2022 Pritom Saha Akash, Jie Huang, Kevin Chen-Chuan Chang

It then uses the axes to model a corpus for easily understandable representation.

Domain Representative Keywords Selection: A Probabilistic Approach

1 code implementation Findings (ACL) 2022 Pritom Saha Akash, Jie Huang, Kevin Chen-Chuan Chang, Yunyao Li, Lucian Popa, ChengXiang Zhai

We propose a probabilistic approach to select a subset of a \textit{target domain representative keywords} from a candidate set, contrasting with a context domain.

Exploring Variational Graph Auto-Encoders for Extract Class Refactoring Recommendation

no code implementations16 Mar 2022 Pritom Saha Akash, Kevin Chen-Chuan Chang

Then, the variational graph auto-encoder is used to learn a vector representation for each method.
