This book was released on 2011-04-07 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reasoning for Information: Seeking and Planning Dialogues provides a logic-based reasoning component for spoken language dialogue systems. This component, called Problem Assistant is responsible for processing constraints on a possible solution obtained from various sources, namely user and the system's domain-specific information. The authors also present findings on the implementation of a dialogue management interface to the Problem Assistant. The dialogue system supports simple mixed-initiative planning interactions in the TRAINS domain, which is still a relatively complex domain involving a number of logical constraints and relations forming the basis for the collaborative problem-solving behavior that drives the dialogue.

Download or read book User Models in Dialog Systems written by Alfred Kobsa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: User models have recently attracted much research interest in the field of artificial intelligence dialog systems. It has become evident that flexible user-oriented dialog behavior of such systems can be achieved only if the system has access to a model of the user containing assumptions about his/her background knowledge as well as his/her goals and plans in consulting the system. Research in the field of user models investigates how such assumptions can be automatically created, represented and exploited by the system in the course of an "on-line" interaction with the user. The communication medium in this interaction need not necessarily be a natural language, such as English or German. Formal interaction languages are also permit ted. The emphasis is placed on systems with natural language input and output, however. A dozen major and several more minor user modeling systems have been de signed and implemented in the last decade, mostly in the context of natural-language dialog systems. The goal of UM86, the first international workshop on user model ing, was to bring together the researchers working on these projects so that results could be discussed and analyzed, and hopefully general insights be found, that could prove useful for future research. The meeting took place in Maria Laach, a small village some 40 miles south of Bonn, West Germany. 25 prominent researchers were invited to participate.

Available in PDF, EPUB and Kindle. Book excerpt: Human conversational partners are able, at least to a certain extent, to detect the speaker’s or listener’s emotional state and may attempt to respond to it accordingly. When instead one of the interlocutors is a computer a number of questions arise, such as the following: To what extent are dialogue systems able to simulate such behaviors? Can we learn the mechanisms of emotional be- viors from observing and analyzing the behavior of human speakers? How can emotionsbeautomaticallyrecognizedfromauser’smimics,gesturesandspeech? What possibilities does a dialogue system have to express emotions itself? And, very importantly, would emotional system behavior be desirable at all? Given the state of ongoing research into incorporating emotions in dialogue systems we found it timely to organize a Tutorial and Research Workshop on A?ectiveDialogueSystems(ADS2004)atKlosterIrseein GermanyduringJune 14–16, 2004. After two successful ISCA Tutorial and Research Workshops on Multimodal Dialogue Systems at the same location in 1999 and 2002, we felt that a workshop focusing on the role of a?ect in dialogue would be a valuable continuation of the workshop series. Due to its interdisciplinary nature, the workshop attracted submissions from researchers with very di?erent backgrounds and from many di?erent research areas, working on, for example, dialogue processing, speech recognition, speech synthesis, embodied conversational agents, computer graphics, animation, user modelling, tutoring systems, cognitive systems, and human-computer inter- tion.

Researchers and professionals in natural language systems will find this important new book an invaluable addition to their libraries.

Download or read book Computational Models of Mixed Initiative Interaction written by Susan Haller and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational Models of Mixed-Initiative Interaction brings together research that spans several disciplines related to artificial intelligence, including natural language processing, information retrieval, machine learning, planning, and computer-aided instruction, to account for the role that mixed initiative plays in the design of intelligent systems. The ten contributions address the single issue of how control of an interaction should be managed when abilities needed to solve a problem are distributed among collaborating agents. Managing control of an interaction among humans and computers to gather and assemble knowledge and expertise is a major challenge that must be met to develop machines that effectively collaborate with humans. This is the first collection to specifically address this issue.

Download or read book Two Topics in Deep Learning Based Dialogue Systems written by Jinglun Cai and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building more intelligent and more resourceful dialogue systems has been a long sought-after goal in Artificial Intelligence and Natural Language Processing. In this dissertation, we investigate two topics in deep learning based dialogue systems: Leveraging Knowledge Graph (KG) in Query Rewriting (QR), and balancing multi-domain corpora in response generation. Query rewriting is a critical component in dialogue systems to reduce frictions caused by systematic errors or user ambiguity. When there is an entity error, it imposes extra difficulties for a dialogue system to produce satisfactory interpretation. Knowledge Graph information can be beneficial for query rewriting, as common queries for dialogue systems are often related to external knowledge like celebrity names, artworks names, and locations. In this dissertation, we investigate how to incorporate knowledge graph for query rewriting. In particular, we study knowledge graph based entity retrieval in query rewriting. We utilize neural encoders to produce utterance/entity embeddings, and similarity search for entity retrieval. We incorporate KG to provide graph structural information (neighboring entities in KG encoded by Graph Neural Network) and textual information (KG entity descriptions encoded by RoBERTa). Experimental results show that both hard negative sampling and incorporation of knowledge graph consistently improve retrieval precision on all test sets. We observe large performance gain from utilizing KG on few-shot test entities. This shows that external knowledge information is particularly beneficial for dealing with rarely seen cases. Open-domain conversational systems are assumed to generate good responses on multiple domains. Previous work achieved good performance on a single corpus, but combining multiple corpora from different domains is less studied. In this dissertation, we explore methods that deal with multi-domain corpora. We first investigate interleaved learning which intermingles multiple corpora as the baseline. We then investigate two multi-domain learning methods, labeled learning and multi-task labeled learning, which encode each corpus through a unique embedding. Furthermore, we propose Domain-specific Frequency (DF), a novel word-level importance weight that measures the relative importance of a word in a specific corpus compared to multiple corpora. Based on DF, we propose weighted learning, a method that integrates DF to the loss function, and we also adopt DF as a new evaluation metric. Extensive experiments show that our methods gain significant improvements on both automatic and human evaluation. We share our code and data for reproducibility. Our main contributions are the following: 1. We propose a knowledge graph enhanced system for query rewriting, leveraging both graph neighbor information and entity textual description. 2. We propose labeled learning and multi-task labeled learning for open domain, and show these two methods achieve significant improvements on automatic and human evaluation.

Download or read book Situated Dialogue Systems written by Robert J. Ross and published by Createspace Indie Pub Platform. This book was released on 2011-01-01 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: For 50 years the natural language interface has tempted and challenged researchers and the public in equal measure. As advanced domains such as robotic systems mature over the next ten years, the need for effective language interfaces will become more significant as the disparity between physical and language ability becomes more evident. Natural language conversation with robots and other situated systems will not only require a clear understanding of theories of language use, models of spatial representation and reasoning, and theories of intentional action and agency – but will also require that all of these models be made accessible within tractable dialogue processing frameworks. While such issues pose research questions which are significant, particularly when we consider them in the light of the many other challenges in language processing and spatial theory, the benefits of competence in situated dialogue to the fields of robotics, geographic information systems, game design, and applied artificial intelligence cannot be underestimated. This book examines the burgeoning field of Situated Dialogue Systems and describes for the first time a complete computational model of situated dialogue competence for practical dialogue systems. The book can be broadly broken down into two parts. The first three chapters examine on one hand the issues which complicate the computational modelling of situated dialogue, i.e., issues of agency and spatial language competence, and on the other hand examines theories of dialogue modelling and management with respect to the needs of the situated domain. The second part of the book then details a situated dialogue processing architecture. Novel features of this architecture include the modular integration of an intentionality model alongside an exchange-structure based organization of discourse, plus the use of a functional contextualization process that operates over both implicit and explicit content in user contributions. The architecture is described at a course level, but in sufficient detail for others to use as a starting point in their own explorations of situated language intelligence.
