Controlled Text Generation with Hidden Representation Transformations

1 code implementation30 May 2023 Vaibhav Kumar, Hana Koorehdavoudi, Masud Moshtaghi, Amita Misra, Ankit Chadha, Emilio Ferrara

We propose CHRT (Control Hidden Representation Transformation) - a controlled language generation framework that steers large language models to generate text pertaining to certain attributes (such as toxicity).

Teacher-Student Learning Paradigm for Tri-training: An Efficient Method for Unlabeled Data Exploitation

no code implementations25 Sep 2019 Yash Bhalgat, Zhe Liu, Pritam Gundecha, Jalal Mahmud, Amita Misra

Given that labeled data is expensive to obtain in real-world scenarios, many semi-supervised algorithms have explored the task of exploitation of unlabeled data.

Using Structured Representation and Data: A Hybrid Model for Negation and Sentiment in Customer Service Conversations

no code implementations WS 2019 Amita Misra, Mansurul Bhuiyan, Jalal Mahmud, Saurabh Tripathy

We further investigate the results of negation scope detection for the sentiment prediction task on customer service conversation data using both a traditional SVM and a Neural Network.

SlugNERDS: A Named Entity Recognition Tool for Open Domain Dialogue Systems

no code implementations LREC 2018 Kevin K. Bowden, Jiaqi Wu, Shereen Oraby, Amita Misra, Marilyn Walker

In dialogue systems, the tasks of named entity recognition (NER) and named entity linking (NEL) are vital preprocessing steps for understanding user intent, especially in open domain interaction where we cannot rely on domain-specific inference.

Slugbot: An Application of a Novel and Scalable Open Domain Socialbot Framework

no code implementations4 Jan 2018 Kevin K. Bowden, Jiaqi Wu, Shereen Oraby, Amita Misra, Marilyn Walker

In this paper we introduce a novel, open domain socialbot for the Amazon Alexa Prize competition, aimed at carrying on friendly conversations with users on a variety of topics.

Summarizing Dialogic Arguments from Social Media

no code implementations31 Oct 2017 Amita Misra, Shereen Oraby, Shubhangi Tandon, Sharath TS, Pranav Anand, Marilyn Walker

We show that we can identify the most important arguments by using the dialog context with a best F-measure of 0. 74 for gun control, 0. 71 for gay marriage, and 0. 67 for abortion.

Combining Search with Structured Data to Create a More Engaging User Experience in Open Domain Dialogue

no code implementations15 Sep 2017 Kevin K. Bowden, Shereen Oraby, Jiaqi Wu, Amita Misra, Marilyn Walker

The greatest challenges in building sophisticated open-domain conversational agents arise directly from the potential for ongoing mixed-initiative multi-turn dialogues, which do not follow a particular plan or pursue a particular fixed information need.

Are you serious?: Rhetorical Questions and Sarcasm in Social Media Dialog

no code implementations WS 2017 Shereen Oraby, Vrindavan Harrison, Amita Misra, Ellen Riloff, Marilyn Walker

We present experiments to distinguish between these uses of RQs using SVM and LSTM models that represent linguistic features and post-level context, achieving results as high as 0. 76 F1 for "sarcastic" and 0. 77 F1 for "other" in forums, and 0. 83 F1 for both "sarcastic" and "other" in tweets.

Debbie, the Debate Bot of the Future

no code implementations10 Sep 2017 Geetanjali Rakshit, Kevin K. Bowden, Lena Reed, Amita Misra, Marilyn Walker

Chatbots are a rapidly expanding application of dialogue systems with companies switching to bot services for customer support, and new applications for users interested in casual conversation.

Data-Driven Dialogue Systems for Social Agents

no code implementations10 Sep 2017 Kevin K. Bowden, Shereen Oraby, Amita Misra, Jiaqi Wu, Stephanie Lukin

In order to build dialogue systems to tackle the ambitious task of holding social conversations, we argue that we need a data driven approach that includes insight into human conversational chit chat, and which incorporates different natural language processing modules.

Measuring the Similarity of Sentential Arguments in Dialog

no code implementations6 Sep 2017 Amita Misra, Brian Ecker, Marilyn A. Walker

Debate websites produce curated summaries of arguments on such topics; these summaries typically consist of lists of sentences that represent frequently paraphrased propositions, or labels capturing the essence of one particular aspect of an argument, e. g.

Using Summarization to Discover Argument Facets in Online Ideological Dialog

no code implementations3 Sep 2017 Amita Misra, Pranav Anand, Jean E. Fox Tree, Marilyn Walker

What are the CENTRAL PROPOSITIONS associated with different stances on an issue, what are the abstract objects under discussion that are central to a speaker's argument?

Topic Independent Identification of Agreement and Disagreement in Social Media Dialogue

no code implementations WS 2013 Amita Misra, Marilyn Walker

Research on the structure of dialogue has been hampered for years because large dialogue corpora have not been available.

A Semi-Supervised Approach to Detecting Stance in Tweets

no code implementations3 Sep 2017 Amita Misra, Brian Ecker, Theodore Handleman, Nicolas Hahn, Marilyn Walker

Stance classification aims to identify, for a particular issue under discussion, whether the speaker or author of a conversational turn has Pro (Favor) or Con (Against) stance on the issue.
