  • Motivated by psycholinguistic findings that eye gaze is tightly linked to human language production, we developed an unsupervised approach based on translation models to automatically learn the mappings between words and objects on a graphic display during human machine conversation. The experimental results indicate that user eye gaze can provide useful information to establish such mappings, which have important implications in automatically acquiring and interpreting user vocabularies for conversational systems. ...

  • CarSim is an automatic text-to-scene conversion system. It analyzes written descriptions of car accidents and synthesizes 3D scenes of them. The conversion process consists of two stages. An information extraction module creates a tabular description of the accident and a visual simulator generates and animates the scene. We implemented a first version of CarSim that considered a corpus of texts in French. We redesigned its linguistic modules and its interface and we applied it to texts in English from the National Transportation Safety Board in the United States. ...

  • To enable conversational QA, it is important to examine key issues addressed in conversational systems in the context of question answering. In conversational systems, understanding user intent is critical to the success of interaction. Recent studies have also shown that the capability to automatically identify problematic situations during interaction can significantly improve the system performance. Therefore, this paper investigates the new implications of user intent and problematic situations in the context of question answering. ...

  • Work on Deisboeck and Kresh's Complex Systems Science in BioMedicine started years ago. In fact, thoughts and ideas leading up to this textbook date back to our first conversation, sometime in the fall of 1996. We quickly found common ground, and talked about emergence and self-organization and their relevance for medicine. We were both fascinated by the idea of complexity and marveled about its tremendous possibilities for cancer research, which was then and still is Tom's main scientific interest. Much has happened in science and technology since we first discussed our vision.

  • 2007, I wrote an ebook called “Save the Pixel—the Art of Simple Web Design,” which teaches that simplicity is the key to designing web pages that work. Th e book has sold more than 8,000 copies, and my agency Scratchmedia has become well known for the clean, spacious design style. Aft er I presented on simple web design at Ken McCarthy’s System Intensive seminar in 2008, I was asked what evidence I could share that proved the eff ectiveness of my approach. I was shocked to realize I had no numbers to prove that simplicity works!...

  • An increasing number of telephone services are offered in a fully automatic way with the help of speech technology. The underlying systems, called spoken dialogue systems (SDSs), possess speech recognition, speech understanding, dialogue management, and speech generation capabilities, and enable a more-or-less natural spoken interaction with the human user. Nevertheless, the principles underlying this type of interaction are different from the ones which govern telephone conversations between humans, because of the limitations of the machine interaction partner.

  • This book is based on publications from the ISCA Tutorial and Research Workshop on Multi-Modal Dialogue in Mobile Environments held at Kloster Irsee, Germany, in 2002. The workshop covered various aspects of development and evaluation of spoken multimodal dialogue systems and components with particular emphasis on mobile environments, and discussed the state-ofthe- art within this area. On the development side the major aspects addressed include speech recognition, dialogue management, multimodal output generation, system architectures, full applications, and user interface issues.

  • Individual utterances often serve multiple communicative purposes in dialogue. We present a data-driven approach for identification of multiple dialogue acts in single utterances in the context of dialogue systems with limited training data. Our approach results in significantly increased understanding of user intent, compared to two strong baselines.

  • The Automatic Content Linking Device is a just-in-time document retrieval system which monitors an ongoing conversation or a monologue and enriches it with potentially related documents, including multimedia ones, from local repositories or from the Internet. The documents are found using keyword-based search or using a semantic similarity measure between documents and the words obtained from automatic speech recognition.

  • Correct stress placement is important in text-to-speech systems, in terms of both the overall accuracy and the naturalness of pronunciation. In this paper, we formulate stress assignment as a sequence prediction problem. We represent words as sequences of substrings, and use the substrings as features in a Support Vector Machine (SVM) ranker, which is trained to rank possible stress patterns. The ranking approach facilitates inclusion of arbitrary features over both the input sequence and output stress pattern. ...

  • We present the first English syllabification system to improve the accuracy of letter-tophoneme conversion. We propose a novel discriminative approach to automatic syllabification based on structured SVMs. In comparison with a state-of-the-art syllabification system, we reduce the syllabification word error rate for English by 33%. Our approach also performs well on other languages, comparing favorably with published results on German and Dutch.

  • We demonstrate one aspect of an affectextraction system for use in intelligent conversational agents. This aspect performs a degree of affective interpretation of some types of metaphorical utterance. of metaphor, with a significant degree of linguistic open-endedness. Also, note that our overarching research aim is to study metaphor as such, not just how it arises in e-drama. This increases our need for systematic, open-ended methods.
