TLDR
A predictive model of debate is proposed that estimates the effects of linguistic features and the latent persuasive strengths of different topics, as well as the interactions between the two, and finds that winning sides employ stronger arguments.Abstract:
Debate and deliberation play essential roles in politics and government, but most models presume that debates are won mainly via superior style or agenda control Ideally, however, debates would be won on the merits, as a function of which side has the stronger arguments We propose a predictive model of debate that estimates the effects of linguistic features and the latent persuasive strengths of different topics, as well as the interactions between the two Using a dataset of 118 Oxford-style debates, our model's combination of content (as latent topics) and style (as linguistic features) allows us to predict audience-adjudicated winners with 74% accuracy, significantly outperforming linguistic features alone (66%) Our model finds that winning sides employ stronger arguments, and allows us to identify the linguistic features associated with strong or weak argumentsread more

Argument Generation with Retrieval, Planning, and Realization
Xinyu Hua,Zhe Hu,Lu Wang +2 more
TL;DR: This paper presents a novel framework, CANDELA, which consists of a powerful retrieval system and a novel two-step generation model, where a text planning decoder first decides on the main talking points and a proper language style for each sentence, then a content realization decoder reflects the decisions and constructs an informative paragraph-level argument.

Neural Argument Generation Augmented with Externally Retrieved Evidence
Xinyu Hua,Lu Wang +1 more
TL;DR: This article proposed an encoder-decoder style neural network-based argument generation model enriched with externally retrieved evidence from Wikipedia, which generates a set of talking point phrases as intermediate representation, followed by a separate decoder producing the final argument based on both input and the keyphrases.

Trouble on the Horizon: Forecasting the Derailment of Online Conversations as they Develop
TL;DR: This work introduces a conversational forecasting model that learns an unsupervised representation of conversational dynamics and exploits it to predict future derailment as the conversation develops, and shows that it outperforms state-of-the-art systems at forecasting derailment.

TL;DR: In this article, an apex seal for a rotary combustion engine is disclosed having a hollow, thin wall, tubular, metal core member embedded in an extruded composite metal-carbon matrix, adapted to slideably engage the slot of the rotor in which it rides and sealingly engage the rotor housing against which it is spring and gas pressure biased.

Accurate Unlexicalized Parsing
Dan Klein,Christopher D. Manning +1 more
TL;DR: It is demonstrated that an unlexicalized PCFG can parse much more accurately than previously shown, by making use of simple, linguistically motivated state splits, which break down false independence assumptions latent in a vanilla treebank grammar.
