Este trabalho apresenta um estudo sobre como a tecnologia adaptativa pode ser utilizada para aprimorar métodos existentes de gerenciamento de diálogo. O gerenciamento de diálogo é a atividade central em um sistema computacional de diálogo falado, sendo a responsável por decidir as ações comunicativas que devem ser enviadas ao usuário. Para evidenciar pontos que pudessem ser melhorados através do uso da tecnologia adaptativa, faz-se uma revisão literária ampla do gerenciamento do diálogo. Esta revisão também permite elencar critérios existentes e criar outros novos para avaliar gerenciadores de diálogos. Um modelo de gerenciamento adaptativo baseado em máquinas de estados, denominado Adaptalker, é então proposto e utilizado para criar um framework de desenvolvimento de gerenciadores de diálogo, o qual foi exercitado pelo desenvolvimento ilustrativo de uma aplicação simples de venda de pizzas. A análise desse exemplo permite observar como a adaptatividade é utilizada para aperfeiçoar o modelo, tornando-o capaz, por exemplo, de lidar de forma mais eficiente tanto com o reparo do diálogo quanto com a iniciativa do usuário. As regras de gerenciamento do Adaptalker são organizadas em submáquinas, que trabalham de forma concorrente para decidir qual a próxima ação comunicativa.; This work presents a study on how to apply adaptive technologies to improve existing dialog management methodologies.

This manual describes a method for annotating rhetorical relations, adjacency pairs, and other argumentation acts found in task-oriented spoken dialog [Traum, 1993; Traum and Hinkelman, 1992]. It is largely aimed at the novice annotator rather than the computational linguist, and therefore in choosing terminology we have valued intuitiveness over precision. This work came out of an exploration of how to mark structure above the speech act in the Monroe corpus [Stent, 2000 (TN 99-2)]. For more information about the development of this manual, see [Stent, 2000 (INLG)]. This tool is designed for use with ArgumentationTool, a tool for marking argumentation acts in dialog that is available from http://www.cs.rochester.edu/research/cisd/resources/aad/.

Currently, the TRAINS dialog system uses a more or less standard chart parser as the interface between the text of the dialog and the rest of the dialog processing system. However, traditional chart parsers are not well equipped to handle dialogs because dialog constituents can be discontinuous, with interspersed acknowledgments, editing terms, repairs, etc. This paper proposes some modifications of the current TRAINS parser enabling it to handle discontinuous dialog structure. The representation of a dialog is still superficially hierarchical (rather than consisting of interleaved structures). This is made possible by two devices: one is to accommodate repairs (e.g., to uh .. to Corning) through explicit grammar rules; the other is to accommodate mid-sentence acknowledgments (e.g., okay), editing terms (e.g., uh), etc. as ``trailers" attached to lexical items. We show how this works on a simple sample dialog. Because allowing for repairs and interruptions introduces much ambiguity, we also discuss some initial disambiguation techniques.

Die Dissertation untersucht die Entwicklung des christlich-jüdischen Dialogs in Deutschland. im Zeitraum ab der Nachkriegszeit (1948) bis 2009. Hierbei richtet sich das Augenmerk vor allem auf die deutschen Vereine „Gesellschaften für christlich-jüdische Zusammenarbeit“. Diese haben sich in ihren Satzungen der Überwindung religiöser Vorurteile verpflichtet. Die Arbeit intendiert, über die Optionen zur Entlarvung und Bekämpfung von Vorurteilen über Menschen anderer Religionen, insbesondere von mythisch-irrationalen Klischeebildern über Menschen jüdischen Glaubens, aufzuklären. Dies erfolgt anhand konkreter Beispiele aus der Lebenswelt von Vereinsmitgliedern, die sich für interreligiöse, schwerpunktmäßig christlich-jüdische Veranstaltungen einsetzen. Thematisiert wird in der Dissertation nicht ausschließlich der Religionsdialog unter Geistlichen, sondern im Mittelpunkt steht die Dokumentation und Analyse der Kooperation von Menschen unterschiedlicher ideologischer Ausgangspunkte, Atheisten eingeschlossen. Ausgangspunkt für die Untersuchungen war die Hypothese, dass permanente, friedliche und effektive Zusammenarbeit möglich sei, ohne dass die Teilnehmer an der Zusammenarbeit ihre individuellen Glaubensweisen einander angleichen. Die Dissertation ist eine religionshistorische Arbeit zu einem aktuellem Thema und ist zum Teil parallel zu den laufenden Geschehnissen in der christlich-jüdischen Zusammenarbeit (z.B. Reaktionen auf die neue Karfreitagsfürbitte) entstanden. Die Analyse erfolgte aus einem religionssoziologischen Blickwinkel. Wesentlich ist dabei die Gegenüberstellung von Selbst- und Fremdbild dreier religiöser Gruppen (Katholiken...

Der interkulturelle Dialog hat von realistisch-weltkundigen Voraussetzungen auszugehen. Er findet in einem Kontext statt, der viele Ähnlichkeiten mit weltwirtschaftlichen Strukturmerkmalen aufweist. Im Beitrag werden diese Strukturanalogien erläutert und dafür plädiert, historisch-komparativ erschließbare Erfahrungen, vor allem ein realistisches Bild der Kulturkonflikte in der europäischen Geschichte, für einen solchen Dialog nutzbar zu machen.; The intercultural dialog has to go out from realistic-world-expert conditions. He takes place in a context which shows many resemblances to world-economic structure characteristics. In this text these structure analogies are explained and are pleaded to make historical-comparatively developable experiences, above all, a realistic picture of the cultural conflicts in the European history, usable for such a dialog.

In this paper, we describe a conversational agent which provides academic information. The dialog model of this agent has been developed by means of a statistical methodology that automatically explores the dialog space and allows learning new enhanced dialog strategies from a dialog corpus. A dialog simulation technique has been applied to acquire data required to train the dialog model and then explore the new dialog strategies. A set of measures has also been defined to evaluate the dialog strategy. The results of the evaluation show how the dialogmodel deviates from the initially predefined strategy, allowing the conversational agent to tackle new situations and generate new coherent answers for the situations already present in the initial corpus. The proposed technique can be used not only to develop new dialog managers but also to explore new enhanced dialog strategies focused on user adaptation required to interact in AmI environments.; Research funded by projects CICYT TIN2011-28620-C02-01, CICYT TEC2011-28626-C02-02, CAM CONTEXTS (S2009/TIC-1485), and DPS2008-07029-C02-02.; Proceedings of: 3rd International Symposium on Ambient Intelligence (ISAmI 2012).

In this paper, we present an agent-based dialog simulation technique for learning new dialog strategies and evaluate conversational agents. Using this technique the effort necessary to acquire data required to train the dialog model and then explore new dialog strategies is considerably reduced. A set of measures has also been defined to evaluate the dialog strategy that is automatically learned and compare different dialog corpora. We have applied this technique to explore the space of possible dialog strategies and evaluate the dialogs acquired for a conversational agent that collects monitored data from patients suffering from diabetes.; Funded by projects CICYT TIN2008-06742-C02-02/TSI, CICYT TEC2008-06732-C02- 02/TEC, CAM CONTEXTS (S2009/TIC-1485), and DPS2008-07029-C02-02.; Proceedings of: 9th International Conference on Practical Applications of Agents and Multiagent Systems (PAAMS 11).

During recent years, conversational agents have become a solution to provide straightforward and more natural ways of retrieving information in the digital domain. In this article, we present an agent-based dialog simulation technique for learning new dialog strategies and evaluating conversational agents. Using this technique, the effort necessary to acquire data required to train the dialog model and then explore new dialog strategies is considerably reduced. A set of measures has also been defined to evaluate the dialog strategy that is automatically learned and to compare different dialog corpora. We have applied this technique to explore the space of possible dialog strategies and evaluate the dialogs acquired for a conversational agent that collects monitored data from patients suffering from diabetes. The results of the comparison of these measures for an initial corpus and a corpus acquired using the dialog simulation technique show that the conversational agent reduces the time needed to complete the dialogs and improve their quality, thereby allowing the conversational agent to tackle new situations and generate new coherent answers for the situations already present in an initial model.; This work was supported in part by Projects MINECO TEC2012-37832-C02-01...

Multimodal dialog systems can be defined as computer systems that process two or more user input modes and combine them with multimedia system output. This paper is focused on the multimodal input, providing a proposal to process and fusion the multiple input modalities in the dialog manager of the system, so that a single combined input is used to select the next system action. We describe an application of our technique to build multimodal systems that process user's spoken utterances, tactile and keyboard inputs, and information related to the context of the interaction. This information is divided in our proposal into external and internal context, user's internal, represented in our contribution by the detection of their intention during the dialog and their emotional state.; This work was supported in part by Projects MINECO TEC2012-37832-C02-01, CICYT TEC2011-28626-C02-02, CAM CONTEXTS (S2009/TIC-1485).; Proceedings of: PAAMS 2014 International Workshops.

Multimodal dialog systems have demonstrated a high potential for more flexible, usable and natural humancomputer interaction. These improvements are highly dependent on the fusion and dialog management processes, which respectively integrates and interprets multimedia multimodal information and decides the next system response for the current dialog state. In this paper we propose to carry out the multimodal fusion and dialog management processes at the dialog level in a single step. To do this, we describe an approach based on a statistical model that takes user's intention into account, generates a single representation obtained from the different input modalities and their confidence scores, and selects the next system action based on this representation. The paper also describes the practical application of the proposed approach to develop a multimodal dialog system providing travel and tourist information.; This work was supported in part by Projects MINECO TEC2012-37832-C02-01, CICYT TEC2011-28626-C02-02, CAM CONTEXTS (S2009/TIC-1485).; Proceedings of: 17th International Conference on Information Fusion (FUSION 2014): Salamanca, Spain 7-10 July 2014.

Context-aware dialog systems must be able to process very heterogeneous information sources and user input modes. In this paper we propose a method to fuse multimodal inputs into a unified representation. This representation allows the dialog manager of the system to find the best interaction strategy and also select the next system response. We show the applicability of our proposal by means of the implementation of a dialog system that considers spoken, tactile, and also information related to the context of the interaction with its users. Context information is related to the detection of user's intention during the dialog and their emotional state (internal context), and the user's location (external context).; This work was supported in part by Projects MINECO TEC2012-37832-C02-01, CICYT TEC2011-28626-C02-02, CAM CONTEXTS (S2009/TIC-1485).; Proceedings of: 17th International Conference on Information Fusion (FUSION 2014): Salamanca, Spain 7-10 July 2014.

One of the main challenges faced by social robots is how to provide intuitive, natural and enjoyable usability for the end-user. In our ordinary environment, social robots could be important tools for education and entertainment (edutainment) in a variety of ways. This paper presents a Natural Programming System (NPS) that is geared to non-expert users. The main goal of such a system is to provide an enjoyable interactive platform for the users to build different programs within their social robot platform. The end-user can build a complex net of actions and conditions (a sequence) in a social robot via mixed-initiative dialogs and multimodal interaction. The system has been implemented and tested in Maggie, a real social robot with multiple skills, conceived as a general HRI researching platform. The robot's internal features (skills) have been implemented to be verbally accessible to the end-user, who can combine them into others that are more complex following a bottom-up model. The built sequence is internally implemented as a Sequence Function Chart (SFC), which allows parallel execution, modularity and re-use. A multimodal Dialog Manager System (DMS) takes charge of keeping the coherence of the interaction. This work is thought for bringing social robots closer to non-expert users...

Research endeavors on spoken dialogue systems in the 1990s and 2000s have led to the deployment of commercial spoken dialogue systems (SDS) in microdomains such as customer service automation, reservation/booking and question answering systems. Recent research in SDS has been focused on the development of applications in different domains (e.g. virtual counseling, personal coaches, social companions) which requires more sophistication than the previous generation of commercial SDS. The focus of this research project is the delivery of behavior change interventions based on the brief intervention counseling style via spoken dialogue systems. Brief interventions (BI) are evidence-based, short, well structured, one-on-one counseling sessions. Many challenges are involved in delivering BIs to people in need, such as finding the time to administer them in busy doctors' offices, obtaining the extra training that helps staff become comfortable providing these interventions, and managing the cost of delivering the interventions. Fortunately, recent developments in spoken dialogue systems make the development of systems that can deliver brief interventions possible. The overall objective of this research is to develop a data-driven, adaptable dialogue system for brief interventions for problematic drinking behavior...

The study aimed to step into two-person (teacher–student) educational neuroscience. We describe a physiological marker of cortical hemodynamic correlates involved in teacher–student interactions during performance of a classical teaching model, the Socratic dialog. We recorded prefrontal brain activity during dialog execution simultaneously in seventeen teacher–student pairs using functional near-infrared spectroscopy (fNIRS). Our main finding is that students, who successfully transferred the knowledge, showed less activity than those who not showed transfer. Correlation analysis between teacher and student activity indicate that in successful educational dialogs student and teachers ‘dance at the same pace’. This is the first study measuring simultaneously brain activity of teacher–student interactions and paves future investigations of brain networks involved in complex educational interactions.; Fil: Holper, Lisa.

The dialog boxes are useful in case of displaying warnings, errors, confirmations etc. in special situations. A typical dialog box is displayed in a small window with some text message along with a few options for the user to select. However, there are certain difficulties associated in programming and implementing a conventional dialog box, such as, severe programming effort, rigidity of the hard coded message, obscuring screen space and so on. There is a need to overcome these difficulties of the dialog box to make them more efficient and useful. The modality of the dialog boxes also creates some limitations. While modal dialog boxes needs to be closed explicitly by the user, modeless dialog boxes can grow in number and become difficult to control. Thus, an ideal dialog box should be deprived of all the above-mentioned drawbacks. The dialog box should not obscure the screen. The user should be able open multiple dialog boxes but without obscuring the screen. This article analyses 5 interesting inventions on dialog boxes selected from US Patent database. Each invention tries to overcome some limitations of a conventional dialog box and provides some innovative features. Each solution is also analyzed from a TRIZ perspective.; Comment: Available at SSRN: http://ssrn.com/abstract=949247. Mishra...

In this paper, we present a probabilistic framework for goal-driven spoken dialog systems. A new dynamic stochastic state (DS-state) is then defined to characterize the goal set of a dialog state at different stages of the dialog process. Furthermore, an entropy minimization dialog management(EMDM) strategy is also proposed to combine with the DS-states to facilitate a robust and efficient solution in reaching a user's goals. A Song-On-Demand task, with a total of 38117 songs and 12 attributes corresponding to each song, is used to test the performance of the proposed approach. In an ideal simulation, assuming no errors, the EMDM strategy is the most efficient goal-seeking method among all tested approaches, returning the correct song within 3.3 dialog turns on average. Furthermore, in a practical scenario, with top five candidates to handle the unavoidable automatic speech recognition (ASR) and natural language understanding (NLU) errors, the results show that only 61.7\% of the dialog goals can be successfully obtained in 6.23 dialog turns on average when random questions are asked by the system, whereas if the proposed DS-states are updated with the top 5 candidates from the SLU output using the proposed EMDM strategy executed at every DS-state...

We outline how utterances in dialogs can be interpreted using a partial first order logic. We exploit the capability of this logic to talk about the truth status of formulae to define a notion of coherence between utterances and explain how this coherence relation can serve for the construction of AND/OR trees that represent the segmentation of the dialog. In a BDI model we formalize basic assumptions about dialog and cooperative behaviour of participants. These assumptions provide a basis for inferring speech acts from coherence relations between utterances and attitudes of dialog participants. Speech acts prove to be useful for determining dialog segments defined on the notion of completing expectations of dialog participants. Finally, we sketch how explicit segmentation signalled by cue phrases and performatives is covered by our dialog model.; Comment: 17 pages

This is the author accepted manuscript. The final version is available from ACM at http://dl.acm.org/citation.cfm?doid=2742647.2742672.; The wearable revolution, as a mass-market phenomenon, has finally arrived. As a result, the question of how wearables should evolve over the next 5 to 10 years is assuming an increasing level of societal and commercial importance. A range of open design and system questions are emerging, for instance: How can wearables shift from being largely health and fitness focused to tracking a wider range of life events? What will become the dominant methods through which users interact with wearables and consume the data collected? Are wearables destined to be cloud and/or smartphone dependent for their operation? Towards building the critical mass of understanding and experience necessary to tackle such questions, we have designed and implemented ZOE ? a match-box sized (49g) collar- or lapel-worn sensor that pushes the boundary of wearables in an important set of new directions. First, ZOE aims to perform multiple deep sensor inferences that span key aspects of everyday life (viz. personal, social and place information) on continuously sensed data; while also offering this data not only within conventional analytics but also through a speech dialog system that is able to answer impromptu casual questions from users.
