Agents for invocation of web services

Web services are becoming popular and widely accepted on the Internet. UDDI is the standard for publishing and discovery of web services. In this paper, we investigate semantics description of web services based on domain ontology; based on this language, we propose an architecture for invoking agents to consume services within the UDDI registry. The semantics service description language together with agent creation
architecture provides a new way to discover and utilise published web services. This method is flexible and extendable to accomplish complex web service requests.

Service guarantees and customer satisfaction: an empirical study of guarantee type and service experience

Scenario analysis was used to examine empirically the relationships between guarantee type and service experience, and consumer satisfaction, for the service of an Internet Service Provider (ISP). The scenarios involved hypothetical situations in which several factors were varied: the existence of a problem; the invocation of a guarantee, the identity of the invoker; and the manner of resolution of any problem. Alternative service guarantees were associated with each hypothetical experience: a specific guarantee, and an unconditional guarantee. Overall, consumer satisfaction related to the nature of the service experience much more strongly than it did to the difference in guarantee type.

Service guarantee redress options in a hotel environment

Unconditional service guarantees are a popular marketing tool in the hotel industry worldwide. They promise total satisfaction and guests are free to invoke the guarantee whenever they are dissatisfied. While many hotels offer “money-back” compensation following guarantee invocation, others vary the payout depending on the severity of the service failure and still others will only compensate the customer if the problem leading to invocation of the guarantee cannot be fixed. To the researcher’s knowledge, the influence of compensation and fix (i.e., taking action to resolve the problem) on consumers’ perceptions of distributive justice has not been examined previously in a service guarantee context. This paper begins to address this gap by presenting a conceptual model and related propositions, arguing that redress (compensation and fix) is an important predictor of consumers’ perceptions of distributive justice, and that this relationship is moderated by service failure severity.

Service recovery in a service guarantee context

This study employed a 2 x 2 full-factorial, between-subjects design experiment examining the influence of service failure severity and fix on hotel guests’ satisfaction following invocation of a service guarantee. The study involved a sample of 130 online panel members. As expected, guests are less dissatisfied following a minor (versus a major) service failure while satisfaction is enhanced when the problem is corrected. Surprisingly, fix has a stronger influence on satisfaction when a severe failure occurs, and satisfaction evaluations are approximately equal regardless of the severity of the failure when the problem is fixed.

The influence of failure severity and perceived employee effort on consumers' postcomplaint negative WOM intentions in a service guarantee context

This study employed a 2 x 2 full-factorial, between-subjects design experiment examining the influence of failure severity and perceived employee effort on hotel guests’ negative word-ofmouth (WOM) intentions following invocation of a service guarantee. The study involved a sample of 131 online panel members. Results suggest that negative WOM intentions reduced when a greater level of effort is exerted by staff in rectifying the guest’s problem and increased when a more severe failure is experienced. There is a stronger difference in guests’ negative WOM intentions between the high and low employee effort conditions when a minor versus a severe service failure is experienced by guests.

The influence of guarantee compensation and fix on service recovery

This study employed a 3 x 2 full-factorial, between-subjects design experiment examining the influence of service guarantee compensation and fix on hotel guests’ satisfaction following invocation of a service guarantee. The study involved a sample of 390 online panel members. As expected, satisfaction is enhanced when the problem is corrected, however overcompensating guests beyond what was initially promised does not enhance satisfaction evaluations. Increasing compensation from the low to the medium (promised) level results in stronger satisfaction ratings when the problem is fixed versus when it is not.

‘Else-where’ : essays in art, architecture, and cultural production 2002-2011

“Else-where”: Essays in Art, Architecture, and Cultural Production 2002–2011 is a synoptic survey of the representational values given to art, architecture, and cultural production at the closing of the twentieth century and the opening of the twenty-first. Written primarily as a critique of what is suppressed in architecture and what is disclosed in art, the essays are informed by the passage out of post-structuralism and its disciplinary analogues toward the Real (denoted over the course of the studies as the “Real-Irreal,” or “Else-where”). The essays collected in “Else-where” cross various disciplines (inclusive of landscape architecture, architecture, and visual art) to develop a nuanced critique of a renascent formal regard and elective exit from nihilism in art and architecture that is also an invocation of the highest coordinates given to the arts – that is, formal ontology as speculative intelligence itself, or the return of the universal as utopian thought “here-and-now.”

Is narrative identity four-dimensionalist?

The claim that selves are narratively constituted has attained considerable currency in both analytic and continental philosophy. However, a set of increasingly standard objections to narrative identity are also emerging. In this paper, I focus on metaphysically realist versions of narrative identity theory, showing how they both build on and differ from their neo-Lockean counterparts. But I also argue that narrative realism is implicitly committed to a four-dimensionalist, temporal-parts ontology of persons. That exposes narrative realism to the charge that the narratively constituted self, on the one hand, and the self that is the object of much of our everyday self-reference and self-experience, on the other, can’t be the same thing. This conclusion may well force narrativists to abandon metaphysical realism about narrative selves — which, in turn, may leave the invocation of ‘narrativity’ as identity-constituting somewhat under-motivated.

Making intellectual room for persona studies: a new consciousness and a shifted perspective

It is an enormously difficult—and perhaps impossible, but ultimately important—task to comprehensively define the contemporary moment through a particular concept. This introduction and this journal make the claim that both in a pervasive way and to a pandemic extent, there is enormous activity and energy in the production, construction, and exhibition of personas. Something quite extraordinary has shifted over the last twenty years that has led to this intensive focus on constructing strategic masks of identity. The catalyst is the development of online culture and its invocation to personalize the expression of a public self—essentially a persona—regularly and incessantly. This culture of producing and monitoring our public selves is the focus of this journal as online culture blends with everyday culture and leads to an insistent proliferation of personas for both presentation and for strategic purposes in order to manage very new notions of value and reputation. The task of investigating persona is complex, and is dependent on connections and intersections across an array of disciplines. This journal and the field of Persona Studies is designed to serve as a site for this essential work of comprehending, analysing, and critiquing persona, and to allow disciplines to intersect, exchange ideas, and debate the play of persona historically and in contemporary culture.

Exploring the effectiveness of true abnormal data elimination in context-aware web services recommendation

Recent years have witnessed a growing interest in context-aware recommender system (CARS), which explores the impact of context factors on personalized Web services recommendation. Basically, the general idea of CARS methods is to mine historical service invocation records through the process of context-aware similarity computation. It is observed that traditional similarity mining process would very likely generate relatively big deviations of QoS values, due to the dynamic change of contexts. As a consequence, including a considerable amount of deviated QoS values in the similarity calculation would probably result in a poor accuracy for predicting unknown QoS values. In allusion to this problem, this paper first distinguishes two definitions of Abnormal Data and True Abnormal Data, the latter of which should be eliminated. Second, we propose a novel CASR-TADE method by incorporating the effectiveness of True Abnormal Data Elimination into context-aware Web services recommendation. Finally, the experimental evaluations on a real-world Web services dataset show that the proposed CASR-TADE method significantly outperforms other existing approaches.
