An increased number of machine translation services are now available. Unfortunately, none of them can provide adequate translation quality for all input sources. This forces the user to select from among the services according to his needs. However, it is tedious and time consuming to perform this manual selection. Our solution, proposed here, is an automatic mechanism that can select the most appropriate machine translation service. Although evaluation methods are available, such as BLEU, NIST, WER, etc., their evaluation results are not unanimous regardless of the translation sources. We proposed a two-phase architecture for selecting translation services. The first phase uses a data-driven classification to allow the most appropriate evaluation method to be selected according to each translation source. The second phase selects the most appropriate machine translation result by the selected evaluation method. We describe the architecture, detail the algorithm, and construct a prototype. Tests show that the proposal yields better translation quality than employing just one machine translation service.

QoS computation plays an important role in Web service selection. It involves property value preprocessing aspect, user satisfaction calculation aspect, and aggregation of multiple QoS properties aspect. However, little attention has been paid to users participating in QoS computation. In this paper, we examine QoS computation from the angle of experienced users and novice users. An experienced user is able to be more active in providing configuration information such as expected boundary of a QoS property, distribution function of user satisfaction, and the aggregation weight of each QoS property. While a novice user has limited experience to do this. Based on the study of user-centered factors in QoS computation, we propose a user-centered QoS computation, which provides a new choice of normalization in property value preprocessing aspect, an approach of approximation in user satisfaction calculation aspect, and a weight suggestion way in aggregation of multiple properties aspect. A case study in translation service selection shows that the proposed user-centered QoS calculation is more efficient for novice users than random configuration, and much more efficient for experience users. © 2012 IEEE.

Service Composition Scenarios for Task-Oriented Translation. 査読

Chunqi Shi, Donghui Lin, Toru Ishida 0001

Due to instant availability and low cost, machine translation is becoming popular. Machine translation mediated communication plays a more and more important role in international collaboration. However, machine translators cannot guarantee high quality translation. In a multilingual communication task, many in-domain resources, for example domain dictionaries, are needed to promote translation quality. This raises the problem of how to help communication task designers provide higher quality translation systems, systems that can take advantage of various in-domain resources. The Language Grid, a service-oriented collective intelligent platform, allows in-domain resources to be wrapped into language services. For task-oriented translation, we propose service composition scenarios for the composition of different language services, where various in-domain resources are utilized effectively. We design the architecture, provide a script language as the interface for the task designer, which is easy for describing the composition scenario, and make a case study of a Japanese-English campus orientation task. Based on the case study, we analyze the increase in translation quality possible and the usage of in-domain resources. The results demonstrate a clear improvement in translation accuracy when the in-domain resources are used.

Since various communities withmultiple languagesinteract in daily life, tools are needed to support intercultural communication. However, we often observe that the success of a multi-language tool in one situation does not guarantee its success in another. To develop multi-language environments that can handle various situations in various communities, existing language resources should be easy to share and customize. Therefore, we designed the Language Grid as service-oriented collective intelligence; it allows users to freely create language services from existing language resources and combine them to develop new services to meet their own requirements. This paper explains the design concept and service architecture of the Language Grid, and our approach to user involvement in collective intelligence activities. An institutional design is also essential forcollective intelligence. We create a federated operation model to bridgedifferentstake-holders including service providers, service users, and service grid operators.

Service grid is an infrastructure for service-oriented collective intelligence. It provides a set of enabling functionalities to support coordination of services, such as service registries, service composition, access control, and monitoring. To form the service-oriented collective intelligence, various types of services need to be connected on the service grid, and managed by the service grid operator. However, it is difficult for single service grid operator to gather and organize services in various domains. Therefore, building service grids in different domains and connecting these service grids are essential for expanding service-oriented collective intelligence across domains. To this end, we have designed a service domain model to specialize general-purpose service grid to a specific domain and realize interoperability among service grids. Moreover, we have also developed service grid federation architecture to share service registries, compose services across service grids, and control and monitor accesses to the composite services. Finally, we have applied the proposed architecture to the language service domain to construct the Language Grid. © 2012 IEEE.

In recent years, collaborative translation has become more and more important for translation volunteers to share knowledge among different languages, among which Wikipedia translation activity is a typical example. During the collaborative translation processes, users with different mother tongues always conduct frequent discussions about certain words or expressions to understand the content of original article and to decide the correct translation. To support such kind of multilingual discussions, we propose an approach to embedding a service-oriented multilingual infrastructure with discussion functions in collaborative translation systems, where discussions can be automatically translated into different languages with machine translators, dictionaries, and so on. Moreover, we propose a Meta Translation Algorithm to adapt the features of discussions for collaborative translation, where discussion articles always consist of expressions in different languages. Further, we implement the proposed approach on LiquidThreads, a BBS on Wikipedia, and apply it for multilingual discussion for Wikipedia translation to verify the effectiveness of this research. © 2012 IEEE.

Dynamic Service Selection Based on Context-Aware QoS. 査読

With the development of service-oriented computing environments, QoS-aware service selection has been a more and more important research issue. In service composition environments, QoS attributes of atomic services are always aggregated for computing the QoS of the composite services, which has been reported in many previous studies. However, there are situations that some QoS attributes cannot be aggregated for composite services. For example, it is difficult to compute the translation quality of a composite translation service by simply aggregating its component atomic services (machine translation service, morphological analysis service, dictionary service). Moreover, when multiple QoS attributes are used for evaluating services, it is always difficult to maximize all the QoS attributes because there might be anti-correlated relations between them. To address above problems, this paper proposes an approach for selecting services based on context-aware factors of QoS attributes. In our proposed approach, context-aware factors that affect QoS attributes are first extracted from analyzing their correlation with QoS attributes. Then, QoS data is generated based on the extracted factors for QoS prediction and evaluation. Further, dynamic service selection is realized based on QoS prediction and evaluation considering user requirements. We use a case study in the domain of language service with some experiments to show the effectiveness of our approach. © 2012 IEEE.

Since various communities, which use multiple languages, now want to interact in daily life, tools that can effectively support multilingual communication are necessary. However, we often observe that the success of a multilingual tool in one situation does not guarantee its success in another. To develop a multilingual environment that can handle various situations in various communities, existing language resources (dictionaries, parallel texts, part-of-speech taggers, machine translators, etc.) should be easily shared and customized. Therefore, we designed our proposal, the Language Grid, as service-oriented collective intelligence
it allows users to freely create language services from existing language resources and combine those language services to develop new services to meet their own requirements. This chapter explains the design concept and service architecture of the Language Grid, and the approach of user involvement in the collective intelligence activities.

Decision Making of Networked Multiagent Systems for Interaction Structures. 査読

Networked multiagent systems are very popular in large-scale application environments. In networked multiagent systems, the interaction structures can be shaped into the form of networks where each agent occupies a position that is determined by such agent's relations with others. To avoid collisions between agents, the decision of each agent's strategies should match its own interaction position, so that the strategies available to all agents are in line with their interaction structures. Therefore, this paper presents a novel decision-making model for networked multiagent strategies based on their interaction structures, where the set of strategies for an agent is conditionally decided by other agents within its dependence interaction substructure. With the presented model, the resulting strategies available to all agents can minimize the collisions of multiagents regarding their interaction structures, and the model can produce the same resulting strategies for the isomorphic interaction structures. Furthermore, this paper uses a multiagent citation network as a case study to demonstrate the effectiveness of the presented decision-making model.

With the development of service-oriented computing, more and more Web services are provided for users. However, there are situations that services or service processes cannot meet users' requirements in functional QoS dimensions (e.g., translation quality in a machine translation service). Meanwhile, the emergence of crowdsourcing makes various types of tasks done in more and more efficiency ways with low costs. To consider both functional QoS and non-functional QoS, in this paper we try to combine crowdsourcing activities with service processes. Further, this study aims at analyzing the effects of crowd activities on service processes in the real world. We use a case study in the domain of language service with a large scale experiment to show that composing crowd activities and Web services brings variety and creativity to the traditional service processes and human processes. From the experiments and analysis, we find out that quality of crowd activities is essential to service processes, and that crowd activities with high quality can significantly improve various QoS dimensions of the service processes. © 2012 Springer-Verlag.

In service composition environments, users and service entity hosts are always geometrically distributed. Therefore the performance of the service response might be poor when users invoke services that are physically far from them. Such issues are difficult to be solved with traditional caching technologies in the areas of contents delivery network because service providers do not always allow their service entities to be copied to all service entity hosts. In this paper, we deal with the service invocation control problem considering the above issues. First, we formally model the service invocation problem in service composition environments. Then we design several dynamic service invocation control mechanisms to improve the response performance of atomic services and composite services. The evaluation results show that (1) the mechanism for atomic services that considers both potential users for most service invocation requests and potential users for continuous requests can best improve the response performance
(2) the mechanism for composite services that considers the group characteristics of atomic services can improve the response performance more than other mechanisms
and (3) our proposed dynamic mechanisms can bring a stable response performance from the perspective of users.

The Language Grid is an infrastructure for enabling users to share language services developed by language specialists and end user communities. Users can also create new services to support their intercultural/multilingual activities by composing language services from a range of providers. Since the Language Grid takes the service-oriented collective intelligence approach, the platform requires the services management to satisfy stakeholders’ needs: access control for service providers, dynamic service composition for service users, and service grid composition and system configurability for service grid operators. To realize the Language Grid, this chapter describes the design concept and the system architecture of the platform based on the service grid.

The Language Grid is a service-oriented infrastructure for language services. In the Language Grid, machine translation services play important roles in supporting multilingual activities for communities. Although the effectiveness of using machine translation services for multilingual communication has been shown in previous reports, the gap between human translators and machine translators remains huge especially in the domain of localization processes that require high translation quality. In this chapter, we aim at improving localization processes by introducing humans into the loop to utilize machine translation services. We try to compare several different types of localization processes (i.e., absolute machine translation processes, absolute human translation processes and processes by human and machine translation services) in the dimensions of translation quality and translation cost. The experiment results show that monolinguals can help improve the translation quality of machine translators with the aid of community dictionary services, and that collaboration of human and machine translation services make it possible to reduce the cost compared with absolute human translations.

Service-oriented collective intelligence, which creates new value by combining various programs and data as services, requires many participants. Therefore it is crucial for an infrastructure for service-oriented collective intelligence to satisfy various policies of service providers. Some previous works have proposed methods for service selection and adaptation which are required to satisfy service providers' policies. However, they do not show how to check if the selected services and adaptation processes certainly satisfy service providers' policies. In this paper, we propose an execution control framework which realizes service selection and adaptation in order to satisfy service providers' policies. On the framework, the behaviors of composite services are verified against service providers' policies based on model checking. We also formally defined the effect of the proposed execution control APIs. This enabled us to update models for verification at runtime and reduce the search space for verification.

Service-oriented collective intelligence, which creates new value by combining services provided by various organizations via services computing technologies, has been gaining in importance with the development of services computing technologies. Because collective intelligence needs many participants, it is crucial to build a framework where a wide variety of policies of service providers are satisfied. In this paper, we propose an architecture which handles a comprehensive process of service selection, adaptation, and coordination to satisfy policies of service providers. First the system selects services, and then adapts the services to the given policies if any of available services cannot satisfy the policies. To achieve this, we formalized this problem as an extension of constraint satisfaction problem and showed a solution. Moreover, the system often needs to force a composite service to follow protocols given by service providers. Therefore we proposed a method which uses meta-level control functions for composite services in order to change order of service execution. © 2010 IEEE.

With the development of the Internet environments, more and more machine translation tools have become available on the Web, which provides the opportunity for some multilingual communities to use machine translation for communication. However, there exist several major problems in machine translation tools available on the Internet. 1) Translation for specific terms or sentences within communities is always of low quality. 2) Most of the available machine translation tools only provide basic functions of translating sentences, documents or Web pages, and lack necessary communication functions for community users. 3) It is difficult to conduct collaborative work among community users. 4) There is no support for creating customized multilingual environments based on unique community requirements. To address the above issues, we develop the Language Grid Toolbox which enables easy creation of multilingual community sites and customized multilingual environments for communities. For example, Toolbox has the basic function of creating language resources like dictionaries, which are used to combine with atomic translation services to improve the translation quality. Further, since Toolbox is developed as open source software and provides many basic APIs that can be used for communication, customized functions for communities can be easily developed. Several customized communication tools that are extended from Toolbox basic modules have already been implemented by universities and local government. ©2010 IEEE.

Dynamic Service Invocation Control in Service Composition Environments. 査読

Service composition environments enable people to create, manage, share services, and compose atomic services for their own requirements. Since users and service entity hosts are always distributed in locations in such environments, service responses might be very slow if users invoke services that are physically far from them, which is even slower for invoking composite services. However, those problems cannot be solved using traditional caching technologies in the areas of contents delivery network because service providers in service composition environments always have their own policies about service license issues, and do not allow their service entities to be copied on all service entity hosts. In this paper, we propose the approach of dynamically switching availability of services among service entity hosts based on the invocation request from users, and design several dynamic invocation control mechanisms to improve the response performance of services considering the service license constraints by service providers. Our proposed mechanisms are evaluated by simulation in service composition environments. © 2010 IEEE.
