ExPUNations: Augmenting Puns with Keywords and Explanations

1 code implementation24 Oct 2022 Jiao Sun, Anjali Narayan-Chen, Shereen Oraby, Alessandra Cervone, Tagyoung Chung, Jing Huang, Yang Liu, Nanyun Peng

The tasks of humor understanding and generation are challenging and subjective even for humans, requiring commonsense and real-world knowledge to master.

Context-Situated Pun Generation

1 code implementation24 Oct 2022 Jiao Sun, Anjali Narayan-Chen, Shereen Oraby, Shuyang Gao, Tagyoung Chung, Jing Huang, Yang Liu, Nanyun Peng

In this work, we propose a new task, context-situated pun generation, where a specific context represented by a set of keywords is provided, and the task is to first identify suitable pun words that are appropriate for the context, then generate puns based on the context keywords and the identified pun words.

Style Control for Schema-Guided Natural Language Generation

no code implementations EMNLP (NLP4ConvAI) 2021 Alicia Y. Tsai, Shereen Oraby, Vittorio Perera, Jiun-Yu Kao, Yuheng Du, Anjali Narayan-Chen, Tagyoung Chung, Dilek Hakkani-Tur

Our results show that while high style accuracy and semantic correctness are easier to achieve for more lexically-defined styles with conditional training, stylistic control is also achievable for more semantically complex styles using discriminator-based guided decoding methods.

Learning from Mistakes: Combining Ontologies via Self-Training for Dialogue Generation

no code implementations SIGDIAL (ACL) 2020 Lena Reed, Vrindavan Harrison, Shereen Oraby, Dilek Hakkani-Tur, Marilyn Walker

Here we explore, for the first time, whether it is possible to train an NLG for a new larger ontology using existing training sets for the restaurant domain, where each set is based on a different ontology.

Schema-Guided Natural Language Generation

1 code implementation INLG (ACL) 2020 Yuheng Du, Shereen Oraby, Vittorio Perera, Minmin Shen, Anjali Narayan-Chen, Tagyoung Chung, Anu Venkatesh, Dilek Hakkani-Tur

We train different state-of-the-art models for neural natural language generation on this dataset and show that in many cases, including rich schema information allows our models to produce higher quality outputs both in terms of semantics and diversity.

Maximizing Stylistic Control and Semantic Accuracy in NLG: Personality Variation and Discourse Contrast

no code implementations WS 2019 Vrindavan Harrison, Lena Reed, Shereen Oraby, Marilyn Walker

Neural generation methods for task-oriented dialogue typically generate from a meaning representation that is populated using a database of domain information, such as a table of data describing a restaurant.

Can Neural Generators for Dialogue Learn Sentence Planning and Discourse Structuring?

no code implementations WS 2018 Lena Reed, Shereen Oraby, Marilyn Walker

While neural generation methods integrate sentence planning and surface realization in one end-to-end learning framework, previous work has not shown that neural generators can: (1) perform common sentence planning and discourse structuring operations; (2) make decisions as to whether to realize content in a single sentence or over multiple sentences; (3) generalize sentence planning and discourse relation operations beyond what was seen in training.

Neural MultiVoice Models for Expressing Novel Personalities in Dialog

no code implementations5 Sep 2018 Shereen Oraby, Lena Reed, Sharath TS, Shubhangi Tandon, Marilyn Walker

Natural language generators for task-oriented dialog should be able to vary the style of the output utterance while still effectively realizing the system dialog actions and their associated semantics.

Controlling Personality-Based Stylistic Variation with Neural Natural Language Generators

no code implementations WS 2018 Shereen Oraby, Lena Reed, Shubhangi Tandon, T. S. Sharath, Stephanie Lukin, Marilyn Walker

We show that our most explicit model can simultaneously achieve high fidelity to both semantic and stylistic goals: this model adds a context vector of 36 stylistic parameters as input to the hidden state of the encoder at each time step, showing the benefits of explicit stylistic supervision, even when the amount of training data is large.

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.

Exploring Conversational Language Generation for Rich Content about Hotels

no code implementations LREC 2018 Marilyn A. Walker, Albry Smither, Shereen Oraby, Vrindavan Harrison, Hadar Shemtov

Dialogue systems for hotel and tourist information have typically simplified the richness of the domain, focusing system utterances on only a few selected attributes such as price, location and type of rooms.

TNT-NLG, System 1: Using a statistical NLG to massively augment crowd-sourced data for neural generation

no code implementations E2E NLG Challenge System Descriptions 2018 Shereen Oraby, Lena Reed, Shubhangi Tandon, Stephanie Lukin, Marilyn A. Walker

In the area of natural language generation (NLG), there has been a great deal of interest in end-to-end (E2E) neural models that learn and generate natural language sentence realizations in one step.

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.

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.

Harvesting Creative Templates for Generating Stylistically Varied Restaurant Reviews

"How May I Help You?": Modeling Twitter Customer Service Conversations Using Fine-Grained Dialogue Acts

no code implementations15 Sep 2017 Shereen Oraby, Pritam Gundecha, Jalal Mahmud, Mansurul Bhuiyan, Rama Akkiraju

We characterize differences between customer and agent behavior in Twitter customer service conversations, and investigate the effect of testing our system on different customer service industries.

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.

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.
