Let’s Chat: Understanding User Expectations in Socialbot Interactions

no code implementations NAACL (HCINLP) 2022 Elizabeth Soper, Erin Pacquetet, Sougata Saha, Souvik Das, Rohini Srihari

This paper analyzes data from the 2021 Amazon Alexa Prize Socialbot Grand Challenge 4, in order to better understand the differences between human-computer interactions (HCI) in a socialbot setting and conventional human-to-human interactions.

Dialo-AP: A Dependency Parsing Based Argument Parser for Dialogues

1 code implementation COLING 2022 Sougata Saha, Souvik Das, Rohini K. Srihari

While neural approaches to argument mining (AM) have advanced considerably, most of the recent work has been limited to parsing monologues.

Argument Mining Dependency Parsing

EDU-AP: Elementary Discourse Unit based Argument Parser

1 code implementation SIGDIAL (ACL) 2022 Sougata Saha, Souvik Das, Rohini Srihari

Neural approaches to end-to-end argument mining (AM) are often formulated as dependency parsing (DP), which relies on token-level sequence labeling and intricate post-processing for extracting argumentative structures from text.

Proto-Gen: An end-to-end neural generator for persona and knowledge grounded response generation

no code implementations CCGPK (COLING) 2022 Sougata Saha, Souvik Das, Rohini Srihari

In this paper we detail the implementation of Proto-Gen, an end-to-end neural response generator capable of selecting appropriate persona and fact sentences from available options, and generating persona and fact grounded responses.

UB Health Miners@SMM4H’22: Exploring Pre-processing Techniques To Classify Tweets Using Transformer Based Pipelines.

no code implementations SMM4H (COLING) 2022 Roshan Khatri, Sougata Saha, Souvik Das, Rohini Srihari

Here we discuss our implementation of two tasks in the Social Media Mining for Health Applications (SMM4H) 2022 shared tasks – classification, detection, and normalization of Adverse Events (AE) mentioned in English tweets (Task 1) and classification of English tweets self-reporting exact age (Task 4).

Steering Conversational Large Language Models for Long Emotional Support Conversations

1 code implementation16 Feb 2024 Navid Madani, Sougata Saha, Rohini Srihari

In this study, we address the challenge of consistently following emotional support strategies in long conversations by large language models (LLMs).

Consolidating Strategies for Countering Hate Speech Using Persuasive Dialogues

no code implementations15 Jan 2024 Sougata Saha, Rohini Srihari

There is now a need to focus on deeper, long-term solutions that involve engaging with the human perpetrator behind the source of the content to change their viewpoint or at least bring down the rhetoric using persuasive means.

Rudolf Christoph Eucken at SemEval-2023 Task 4: An Ensemble Approach for Identifying Human Values from Arguments

no code implementations9 May 2023 Sougata Saha, Rohini Srihari

Our ensemble comprises three models: (i) An entailment-based model for determining the human values based on their descriptions, (ii) A Roberta-based classifier that predicts the set of human values from an argument.

ArgU: A Controllable Factual Argument Generator

no code implementations9 May 2023 Sougata Saha, Rohini Srihari

Our results demonstrate that it is possible to automatically generate diverse arguments exhibiting different inference patterns for the same set of facts by using control codes based on argument schemes and stance.

Diving Deep into Modes of Fact Hallucinations in Dialogue Systems

1 code implementation11 Jan 2023 Souvik Das, Sougata Saha, Rohini K. Srihari

Knowledge Graph(KG) grounded conversations often use large pre-trained models and usually suffer from fact hallucination.

Using Multi-Encoder Fusion Strategies to Improve Personalized Response Selection

no code implementations COLING 2022 Souvik Das, Sougata Saha, Rohini K. Srihari

Ablation studies on the Persona-Chat dataset show that incorporating emotion and entailment improves the accuracy of response selection.

Similarity Based Label Smoothing For Dialogue Generation

no code implementations23 Jul 2021 Sougata Saha, Souvik Das, Rohini Srihari

Generative neural conversational systems are generally trained with the objective of minimizing the entropy loss between the training "hard" targets and the predicted logits.
