It is inadequate to just assure the functional requirements. Quality of service (QoS) must also be satisfied. An important challenge for developing efficient Service Oriented Architecture (SOA) is to maintain the QoS attributes because of compositional and dynamical environment of SOA. It is significant to scrutinize how quality attributes are supported by SOA. However, implementation of SOA pr...

In this paper, we present a computational approach to understanding and augmenting the conversational knowledge process that is a collective activity for knowledge creation, management, and application, where conversational communications are used as a primary means of interaction among participating agents. The key idea is conversation quantization, a technique of approximating a continuous fl...

The author describes a system for defining conversation policies that allows conversants to exchange explicit representations of how they use messages to get things done. This system allows conversation policies to be defined for one or more conversation partners. It does not require that every partner be aware of the other’s conversation policies; however, it does provide more capabilities if ...

A café table is a traditional setting for conversation. Tabletop displays may have an active role in this connection. In particular for a museum scenario, conversation after the visit is important for a joint elaboration of a small group visit experience. We propose the museum café as the location to introduce a tabletop display meant to foster and support conversation about the visit. The goal...

Color is commonly described in terms of the three perceptual attributes-hue, saturation, and brightness-of which only hue has a qualitative nature, saturation and brightness being of a quantitative nature. A possible reason for such a phenomenological structure of the color manifold, and its geometric representation, are discussed.

Actions can create preferences, increasing the value ascribed to commodities acquired at greater cost. This behavioural finding has been observed in a variety of species; however, the causal factors underlying the phenomenon are relatively unknown. We sought to develop a behavioural platform to examine the relationship between effort and reinforcer value in mice trained under demanding or lenie...

Existing open-domain human-computer conversation systems are typically passive: they either synthesize or retrieve a reply provided with a humanissued utterance. It is generally presumed that humans should take the role to lead the conversation and introduce new content when a stalemate occurs, and that computers only need to “respond.” In this paper, we propose STALEMATEBREAKER, a conversation...

This research examined whether children with autism could be trained to improve their conversational skills and whether this led to changes in standard tests of theory of mind (ToM). Three high-functioning children with autism participated in a multiple baseline across participants design. The children were taught how to initiate a conversation, take turns during conversation, listen attentivel...

Complex human actions are modelled as graphs over basic attributes and their spatial and temporal relationships. The attribute dictionary as well as the graphical structure are learned automatically from training data. y(x,w) = D X i=0 wixi 1 The activity model A set C = {ci, c2, . . . , cC} of C complex activities is considered, where each activity ci is modelled as a Graph Gi = (Vi, Ei), and ...
