An expert system approach to assess service performance of travel intermediary

Asian travel industry, in terms of outbound travel markets, has been confronting the global accelerating competition in 21st century. Regarding to the outbound travels, the incumbent travel intermediaries (destination tour operators), the ultimate front-liners of tourism packages provisions is accordingly essential. Technically, estimation on the incumbent travel intermediaries is a series of multiple-criteria decision making (MCDM). Subsequently, this paper executes the implementation of focus group which interviewed 35 travel experts and further integrates the analytic network process approach (ANP) via the insights of host travel agency. Research results objectively enable the Asian travel agencies to evaluate the sustained travel intermediary as well as elaborating the service performance and quality.     

An expert intermediary system for interactive document retrieval

Constructing natural language interfaces to computer systems often requires achievement of advanced reasoning and expert capabilities in addition to basic natural language understanding. In this paper the above issue is tackled in the frame of an actual application concerning the design of a natural language interface for interactive document retrieval. After a short discussion of the peculiarities of this application, which requires both natural language understanding and reasoning capabilities, the general architecture and fundamental design criteria of a system presently being developed at the University of Udine are presented. The system, named IR-NLI, is aimed at allowing non-technical users to directly access through natural language the services offered by online databases. Attention is later focused on the basic functions of IR-NLI, namely understanding, dialogue and reasoning. An example of interaction with IR-NLI is fully worked out to introduce the main features of the system. Knowledge representation methods and algorithms adopted are then illustrated. Perspectives and direction for future research are also discussed.     

Enhancing service system design: An entity interaction pattern approach

The notion of system thinking and the Industrial Marketing and Purchasing Group (IMP)’s findings have been emphasizing that “interaction is the basis analysis unit” of service systems or enterprises. Service system design is an attempt to change the outcome of a service ecosystem and make it more innovative in terms of figuring out not only who those entities are and what their outcomes are, but more importantly how they interact to realize their service values. The design of a service system could accordingly be viewed as changes made to the interactions. In the paper, system entity interactions are classified into patterns to become more analyzable, and different patterns can serve as measurements and guidelines for enterprises to follow and use to gain higher service value. To justify the important role of interaction in the service value creating process, a particular information system is developed and evaluated to explore the benefits of using interaction patterns for enterprise users to create their service values.     

User-centered design of a QoS-based web service selection system

In most of quality of service (QoS)-based web service selection systems, inexperienced end users are not the focal point of the design. Most systems assume that users could formulate their QoS requirements easily and are accurately using the provided query languages. However, oftentimes it is not true. To tackle this issue and emphasize more on the user-centered design of the service selection system, in this paper, we come up with a more expressive and flexible way for non-expert users to define their QoS queries, together with the user support on formulating queries and understanding services in the registry. Then, we propose an enhanced selection model that could handle both exact and fuzzy requirements, return two categories of matching offers—super-exact and partial matches, and rank them using a two-level ranking algorithm. A prototype system is implemented, and experiments are done using a real QoS dataset to show the system performance.     

Applying discrete event simulation to the design of a service delivery system in the aerospace industry: a case study

This paper presents the results of a simulation study concerned with the design of a service delivery system. In particular, it shows how discrete event simulation can be used at the point of signing a long-term service contract to assess whether a service delivery system will be able to comply with the contractual terms over time. This study also proposes a methodology based on the Monte Carlo simulation to estimate the service demand in a context where the installed base evolves dynamically over time. Such a methodology has been used to verify the discrete event simulation model. This research is based on real data from a leading global supplier of human to machine electronic controls operating in the aerospace industry. This supplier has recently signed a major contract for the provision of several devices and related services. These devices will be installed on aircrafts progressively entering service over the next seven years.     

Creating a system for lexical substitutions from scratch using crowdsourcing

This article describes the creation and application of the Turk Bootstrap Word Sense Inventory for 397 frequent nouns, which is a publicly available resource for lexical substitution. This resource was acquired using Amazon Mechanical Turk. In a bootstrapping process with massive collaborative input, substitutions for target words in context are elicited and clustered by sense; then, more contexts are collected. Contexts that cannot be assigned to a current target word’s sense inventory re-enter the bootstrapping loop and get a supply of substitutions. This process yields a sense inventory with its granularity determined by substitutions as opposed to psychologically motivated concepts. It comes with a large number of sense-annotated target word contexts. Evaluation on data quality shows that the process is robust against noise from the crowd, produces a less fine-grained inventory than WordNet and provides a rich body of high precision substitution data at low cost. Using the data to train a system for lexical substitutions, we show that amount and quality of the data is sufficient for producing high quality substitutions automatically. In this system, co-occurrence cluster features are employed as a means to cheaply model topicality.

Customer preferences in mobile game pricing: a service design based case study

This article examines the service design of freemium game pricing. Freemium games are a type of game that is partially free to play, but its players are able to access various options by playing real money. The article increases knowledge of the usability of service design processes in the pricing of mobile games, as well as the understanding of central aspects of freemium pricing models from the perspective of user experience and customer value. Existing research shows that one major reason for failing freemium pricing models is the orientation for technology development, alongside poor content and too aggressive monetization, rather than customer experience. The article presents a process in which an alternative pricing model was developed for freemium games, through the use of service design workshops.

An integrated component design approach to the development of a design information system for customer-oriented product design

In product design, the designer must draw upon many different types of information including both product-user requirements and design developments in related fields. As each designer has his/her own subjective opinion, an appropriate link between the user requirements and design features must be carefully developed to generate the most suitable design recommendation.The objective of this research is to develop a component design approach for the generation and evaluation of feasible design alternatives to help designers make the most effective design decisions. The development of the approach is based on the concept of component design and interaction links between user requirements and design output parameter values so that the design alternatives can be generated. A confidence interval for order statistics is then used to determine if enough unique feasible design alternatives have been generated. The research is presented in conjunction with a ballpoint pen design to demonstrate the feasibility and advantages of this approach.The results should provide designers with a useful method for the development of a design information system that will efficiently generate and evaluate a set of feasible design alternatives in product design process.
