Politeness and Alignment in Dialogues with a Virtual Guide

Language alignment is something that happens automatically in dialogues between human speakers. The ability to align is expected to increase the believability of virtual dialogue agents. In this paper we extend the notion of alignment to affective language use, describing a model for dynamically adapting the linguistic style of a virtual agent to the level of politeness and formality detected in the user’s utterances. The model has been implemented in the Virtual Guide, an embodied conversational agent giving directions in a virtual environment. Evaluation shows that our formality model needs improvement, but that the politeness tactics used by the Guide are mostly interpreted as intended, and that the alignment to the user’s language is noticeable

The Problem of Fake News

Looking at the recent spate of claims about “fake news” which appear to be a new feature of political discourse, I argue that fake news presents an interesting problem in epistemology. Te phenomena of fake news trades upon tolerating a certain indiference towards truth, which is sometimes expressed insincerely by political actors. Tis indiference and insincerity, I argue, has been allowed to fourish due to the way in which we have set the terms of the “public” epistemology that maintains what is considered “rational” public discourse. I argue one potential salve to the problem of fake news is to challenge this public epistemology by injecting a certain ethical consideration back into the discourse

A Flexible pragmatics-driven language generator for animated agents

This paper describes the NECA MNLG; a fully implemented Multimodal Natural Language Generation module. The MNLG is deployed as part of the NECA system which generates dialogues between animated agents. The generation module supports the seamless integration of full grammar rules, templates and canned text. The generator takes input which allows for the specification of syntactic, semantic and pragmatic constraints on the output

Politeness and bias in dialogue summarization: two exploratory studies

In this chapter, two empirical pilot studies on the role of politeness in dialogue summarization are described. In these studies, a collection of four dialogues was used. Each dialogue was automatically generated by the NECA system and the politeness of the dialogue participants was systematically manipulated. Subjects were divided into groups who had to summarize the dialogues from a particular dialogue participant’s point of view or the point of view of an impartial observer. In the first study, there were no other constraints. In the second study, the summarizers were restricted to summaries whose length did not exceed 10% of the number of words in the dialogue that was being summarized. Amongst other things, it was found that the politeness of the interaction is included more often in summaries of dialogues that deviate from what would be considered normal or unmarked. A comparison of the results of the two studies suggests that the extent to which politeness is reported is not affected by how long a summary is allowed to be. It was also found that the point of view of the summarizer influences which information is included in the summary and how it is presented. This finding did not seem to be affected by the constraint in our second study on the summary length

Subtle Discrimination in the Rental Housing Market: Evidence from E-Mail Correspondence of Landlords

We find that landlords practice subtle discrimination in the rental housing market through the use of language associated with describing and viewing a unit, inviting further correspondence, making a formal greeting, and using polite language when replying to e-mail inquiries from a white name more often than to an African American name, they also send longer e-mails and respond quicker to white names

IT’S NOT THEM, IT’S YOU: A CASE STUDY CONCERNING THE EXCLUSION OF NON-WESTERN PHILOSOPHY

My purpose in this essay is to suggest, via case study, that if Anglo-American philosophy is to become more inclusive of non-western traditions, the discipline requires far greater efforts at self-scrutiny. I begin with the premise that Confucian ethical treatments of manners afford unique and distinctive arguments from which moral philosophy might profit, then seek to show why receptivity to these arguments will be low. I examine how ordinary good manners have largely fallen out of philosophical moral discourse in the west, looking specifically at three areas: conditions in the 18th and 19th centuries that depressed philosophical attention to manners; discourse conventions in contemporary philosophy that privilege modes of analysis not well fitted to close scrutiny of manners; and a philosophical culture that implicitly encourages indifference or even antipathy toward polite conduct. I argue that these three areas function in effect to render contemporary discourse inhospitable to greater inclusivity where Confucianism is concerned and thus, more broadly, that greater self-scrutiny regarding unexamined, parochial western commitments and practices is necessary for genuine inclusivity

Coalitional power indices applied to voting systems

We describe voting mechanisms to study voting systems. The classical power indices applied to simple games just consider parties, players or voters. Here, we also consider games with a priori unions, i.e., coalitions among parties, players or voters. We measure the power of each party, player or voter when there are coalitions among them. In particular, we study real situations of voting systems using extended Shapley–Shubik and Banzhaf indices, the so-called coalitional power indices. We also introduce a dynamic programming to compute them.Peer ReviewedPostprint (published version

Pronominal Choice as an Interpersonal Strategy

This paper offers a review of the main aspects of address theory and examines the main interpersonal strategic functions of terms of address. In order to illustrate these issues I have chosen some examples from political discourse. Specifically, I selected three political interviews which took place around the same time (21st April 2003, 16th November 2003 and 30th May 2004), and with the same worldwide conflict in the background (the Iraqi war), but which featured three different interviewees of three different nationalities. Nonetheless, these interviewees share a common characteristic: they held the highest political office in their countries at the time. These interviewees are: Mr. José M. Aznar (President of Spain), Mr. George W. Bush (President of the USA) and Mr. Tony Blair (Prime Minister of the UK). I will try to relate the choice of specific pronominal references to the pragmatic nature of the questions being asked. For this purpose, I will borrow the terms “CC (communicative conflict) question” and “equivocation” from Bavelas, Black, Chovil and Mullett (1990
