Deciphering Political Entity Sentiment in News with Large Language Models: Zero-Shot and Few-Shot Strategies

1 code implementation5 Apr 2024 Alapan Kuila, Sudeshna Sarkar

Employing a chain-of-thought (COT) approach augmented with rationale in few-shot in-context learning, we assess whether this method enhances sentiment prediction accuracy.

A Novel Multi-Stage Prompting Approach for Language Agnostic MCQ Generation using GPT

1 code implementation13 Jan 2024 Subhankar Maity, Aniket Deroy, Sudeshna Sarkar

We introduce a multi-stage prompting approach (MSP) for the generation of multiple choice questions (MCQs), harnessing the capabilities of GPT models such as text-davinci-003 and GPT-4, renowned for their excellence across various NLP tasks.

Harnessing the Power of Prompt-based Techniques for Generating School-Level Questions using Large Language Models

1 code implementation2 Dec 2023 Subhankar Maity, Aniket Deroy, Sudeshna Sarkar

We carefully annotate this dataset as quadruples of 1) Context: a segment upon which the question is formed; 2) Long Prompt: a long textual cue for the question (i. e., a longer sequence of words or phrases, covering the main theme of the context); 3) Short Prompt: a short textual cue for the question (i. e., a condensed representation of the key information or focus of the context); 4) Question: a deep question that aligns with the context and is coherent with the prompts.

In contrast, the anti-government news agencies would focus more on the views of the opponent stakeholders to inform the readers about the shortcomings of government policies.

ArgFuse: A Weakly-Supervised Framework for Document-Level Event Argument Aggregation

1 code implementation ACL (CASE) 2021 Debanjana Kar, Sudeshna Sarkar, Pawan Goyal

Most of the existing information extraction frameworks (Wadden et al., 2019; Veysehet al., 2020) focus on sentence-level tasks and are hardly able to capture the consolidated information from a given document.

A Robust Fuel Optimization Strategy For Hybrid Electric Vehicles: A Deep Reinforcement Learning Based Continuous Time Design Approach

no code implementations1 Jan 2021 Nilanjan Mukherjee, Sudeshna Sarkar

This is followed by the design of a deep reinforcement learning based optimal control law for the non-linear system (i. e., hybrid electric vehicles) such that the actual states and the control policy remain close to the optimal trajectory and optimal policy even in the presence of external disturbances, modeling errors, uncertainties and noise.

UsingWord Embeddings for Query Translation for Hindi to English Cross Language Information Retrieval

no code implementations4 Aug 2016 Paheli Bhattacharya, Pawan Goyal, Sudeshna Sarkar

In this paper, we propose an approach based on word embeddings, a method that captures contextual clues for a particular word in the source language and gives those words as translations that occur in a similar context in the target language.
