abstract = {Introduction: In previous papers (Gordon and Hobbs, 2003, 2004) we have described a methodology for determining what knowledge should be included in the knowledge base for an intelligent agent, capable of constructing and executing plans to achieve its goals. An intelligent agent is at least a planning mechanism, so Gordon (2004) asked what concepts are necessary for the common strategies that people use in achieving their goals. He investigated ten different domains, including politics, personal relationships, artistic performance, and warfare, and collected 372 strategies. He authored representations of these strategies in order to identify a controlled vocabulary involving of concepts. These concepts were categorized into 48 different representational areas, such as sets, space, and time. Thirty of the representational areas, involving 635 concepts, were concerned with commonsense psychology; among these are memory, knowledge management, planning, and so on. This result by itself demonstrates the very great importance of commonsense psychology in the construction of intelligent agents. Gordon et al. (2003) then, to deï¬ne further each of the representational areas, augmented the list of concepts by investigating the English language expressions for concepts in each area. The result was a list of 528 concepts, a set that identiï¬es the target coverage of a formal theory of commonsense psychology. The authors began the development of formal theories that would encompass this list of concepts. In our earlier work (Gordon and Hobbs, 2003), we described the ï¬rst theory we constructed, memory, as an illustration of the method. We have now completed 14 of the 30 theories, and this paper provides an overview of this work as we close in on the halfway mark.},

The use of constructive simulations for training poses a challenge when conducting such reviews, because behavior models are typically designed to simulate satisfactorially, without explicit concern for the interrogation of synthetic entities afterward. Ideally, users could obtain knowledge about not only the choices made by a simulatorEs behavior models, but also the rationale for those choices. This requires a rich representation of behavioral knowledge within the software system. We have integrated our explainable AI system with behavior models and log information from two simulation systems. Selecting examples from these simulators, we identify areas for improvement to facilitate the automation of explanation and tutoring.},

Here we take the perspective of the inhabited environment, that is, environments positioned somewhere on this continuum that are inhabited by virtual (embodied) agents, that interact with each other and with their human partners. Hence, we look at it from the multi-party interaction perspective. In this workshop we will investigate the current state of the art, its shortcomings and a future research agenda.},

We formulate a particular memory strategy (to create an associated obstacle) as a theorem in first-order predicate calculus. We then attempt to validate this strategy by showing that it is entailed by the axioms of the theory we evaluated. These axioms were encoded into the syntax of an automated reasoning system, which was used to automatically generate inferences and search for formal proofs.},

Further more, to address some of the practical issues in previously published methods, we introduce some novel components into the algorithm such as the use of pitch confidence, magnifying window, relative peak measure and relative threshold. By selecting the parameters and thresholds from realistic development sets, this method achieves a 0.972 correlation coefficient on syllable number estimation and a 0.706 correlation on speech rate estimation. This result is about 6.9% improvement than current best single estimator and 3.5% improvement than current multi-estimator evaluated on the same switchboard database.},

abstract = {The importance of automatically recognizing emotions from human speech has grown with the increasing role of spoken language interfaces in human-computer interaction applications. This paper explores the detection of domain-specific emotions using language and discourse information in conjunction with acoustic correlates of emotion in speech signals. The specific focus is on a case study of detecting negative and non-negative emotions using spoken language data obtained from a call center application. Most previous studies in emotion recognition have used only the acoustic information contained in speech. In this paper, a combination of three sources of information-acoustic, lexical, and discourse-is used for emotion recognition. To capture emotion information at the language level, an information-theoretic notion of emotional salience is introduced. Optimization of the acoustic correlates of emotion with respect to classification error was accomplished by investigating different feature sets obtained from feature selection, followed by principal component analysis. Experimental results on our call center data show that the best results are obtained when acoustic and language information are combined. Results show that combining all the information, rather than using only acoustic information, improves emotion classification by 40.7% for males and 36.4% for females (linear discriminant classifier used for acoustic information).},

Since prosody is intricately bound to the semantics of the utterance, recognition of prosodic events is important for spoken language applications such as automatic understanding and translation of speech. Moreover, corpora labeled with prosodic markers are essential for building speech synthesizers that use data-driven approaches to generate natural speech. In this paper, we build a prosody recognition system that detects stress and prosodic boundaries at the word and syllable level in American English using a coupled Hidden Markov Model (CHMM) to model multiple, asynchronous acoustic feature streams and a syntactic-prosodic model that captures the relationship between the syntax of the utterance and its prosodic structure. Experiments show that the recognizer achieves about 75% agreement on stress labeling and 88% agreement on boundary labeling at the syllable level.},

Generally, group strengths found in the early school years become more established at adolescence and remain stable through adulthood. The current study tested whether the patterns established in the early years remained among 30 adult subjects. We also utilized a series of exploratory analyses to determine if observed gender differences were impacted by the covariance present between all cognitive tests. Results suggest that although the patterns established in the early years remain stable through time for males, the established patterns for females are altered with age. Our findings are compelling in supporting a male advantage on visuospatial tasks among older adults. These findings are discussed in terms of common variance between test instruments as a possible source of difference. Our finding that the gender effect tended to increase when common variance was controlled argues that this methodology may enhance the ability to detect domain specific effects.},

abstract = {This special issue describes a number of applications that utilize lifelike characters that teach indirectly, by playing some role in a social interaction with a user. The design of such systems reflects a compromise between competing, sometimes unarticulated de- mands: they must realistically exhibit the behaviors and characteristics of their role, they must facilitate the desired learning, and they must work within the limitations of current technology, and there is little theoretical or empirical guidance on the impact of these compromises on learning. Our perspective on this problem is shaped by our interest in the role of emotion and emotional behaviors in such forms of learning. In recent years, there has been an explosion of interest in the role of emotion in the design of virtual hu- mans. The techniques and motivations underlying these various efforts can seem, from an outsider's perspective, as bewildering and multifaceted as the concept of emotion itself is generally accused of being.
