``Laughing at you or with you'': The Role of Sarcasm in Shaping the Disagreement Space

1 code implementation EACL 2021 Debanjan Ghosh, Ritvik Shrivastava, Smaranda Muresan

We exploit joint modeling in terms of (a) applying discrete features that are useful in detecting sarcasm to the task of argumentative relation classification (agree/disagree/none), and (b) multitask learning for argumentative relation classification and sarcasm detection using deep learning architectures (e. g., dual Long Short-Term Memory (LSTM) with hierarchical attention and Transformer-based architectures).

Topical Stance Detection for Twitter: A Two-Phase LSTM Model Using Attention

no code implementations9 Jan 2018 Kuntal Dey, Ritvik Shrivastava, Saroj Kaushik

The topical stance detection problem addresses detecting the stance of the text content with respect to a given topic: whether the sentiment of the given text content is in FAVOR of (positive), is AGAINST (negative), or is NONE (neutral) towards the given topic.

A Big Data Analysis Framework Using Apache Spark and Deep Learning

no code implementations25 Nov 2017 Anand Gupta, Hardeo Thakur, Ritvik Shrivastava, Pulkit Kumar, Sreyashi Nag

In this paper, we propose a novel framework that combines the distributive computational abilities of Apache Spark and the advanced machine learning architecture of a deep multi-layer perceptron (MLP), using the popular concept of Cascade Learning.

A Paraphrase and Semantic Similarity Detection System for User Generated Short-Text Content on Microblogs

no code implementations COLING 2016 Kuntal Dey, Ritvik Shrivastava, Saroj Kaushik

We propose a set of features that, although well-known in the NLP literature for solving other problems, have not been explored for detecting paraphrase or semantic similarity, on noisy user-generated short-text data such as Twitter.
