From 2004 to 2016 the Leipzig Linguistic Services (LLS) existed as a SOAP-based cyberinfrastructure of atomic micro-services for the Wortschatz project, which covered different-sized textual corpora in more than 230 languages. The LLS were developed in 2004 and went live in 2005 in order to provide a webservice-based API to these corpus databases. In 2006, the LLS infrastructure began to systematically...
Discovering the correct dataset efficiently is critical for computations and effective simulations in scientific experiments. In contrast to searching web documents over the Internet, massive binary datasets are difficult to browse or search. Users must select a reliable data publisher from the large collection of data services available over the Internet. Once a publisher is selected, the user must...
Service providers hosting multi-tiered applications require accurate analytical models of the applications they will host for different system management activities, such as capacity planning, configuration management, cost analysis and feedback control. Due to the complexity of real world scenarios, developing accurate analytical models is hard. This paper presents the commonly faced challenges in...
This paper discusses the real-time data modeling, acquisition and analysis, analyses and designs the real-time data warehouse architecture. In this architecture, the introduction of a multi-level real-time data cache facilitates the real-time data storage. And the using of the Web service to capture real-time data makes the real-time data capture and load easily. This paper also discusses the real-time...
Though the functional relationship analysis for gene products is useful, a convenient and user- friendly tool to measure the functional similarity for genome-wide gene products in multiple species is still not available. We computed the functional similarity of gene products in genome wide in human, mouse and rat based on our algorithm. Database and web services were built based on the precomputed...
Web service combination, which integrates independent and modular distributed services, has loosely coupled, location transparent, protocol independent and other characteristics, but it is still lack of autonomic, self-adaptive and self-organized characteristics, and it's difficult to deal with the complex, dynamic, open and uncertain Internet environment. A framework to improve composition adaptability...
Record linkage, also known as duplicate detection, is a key process that ensures the quality of data stored for Web service data. Given two lists of records, record linkage consists of determining all pairs that are similar to each other, where the overall similarity between two records is defined based on domain-specific similarities over individual attributes constituting the record. In this paper,...
Data as a Service (DaaS) emerges as a new trend for exchanging data between independent data owners and data users so that data can be acquired on demand through standard protocols across heterogeneous platforms. It is usually a user-interactive and iterative process to compose the services into various data-driven business scenarios of data acquisition, analysis, and other processing activities....
Microarrays are state technologies of the art for the measurement of expression of thousands of genes in a single experiment. The treatment of these data are typically performed with a wide range of tools, but the understanding of complex biological system by means of gene expression usually requires integrating different types of data from multiple sources and different services and tools. Many efforts...
Scientific workflow design is usually complex and demands integration of numerous resources. Geographical distribution and semantic heterogeneity of resources add to this complexity. The cost effectiveness of such workflow design thus depends upon the lifespan of the application and its anticipated use. Shorter application lifespan usually entails prohibitive development costs. In this paper, we present...
Large numbers of consumers, businesses, and public entities are now using the Internet for a variety of transactions. This has enabled service providers to offer outsourcing capabilities to business customers using software-as-a-service delivery models in services marketplaces. However, challenges remain in widespread acceptance of such delivery models because they require customers to share business...
In view of the large number of heterogeneous enterprise applications can not be interoperability, not sharing resources, data can not be linked the status quo. OGSA architecture based on the use of the latest GT4 grid development tools to build a data grid platform to integrate existing applications.
Data mining is an important technique in summarize and prediction in different industry. With the help of grid computer, the capability for data storage and efficiency of data mining process can be highly increased. Nowadays, most of studies focus on data replication mechanism and replica selection method, but ignore the part of service replica mechanism which is also important. In the paper, we propose...
OGSA-DQP is a service-based distributed query processor that is able to execute queries over data services and combine data integration with data analysis by invoking Web services. OGSA-DQP currently supports only one type of data source, relational databases wrapped using OGSA-DAI (a middleware tool that exposes XML or relational database management systems as Grid services). OGSA-WebDB is another...
Several vulnerability analysis techniques in web-based applications detect and report on different types of vulnerabilities. However, no single technique provides a generic technology-independent handling of Web-based vulnerabilities. In this paper we present our experience with and experimental exemplification of using the application vulnerability description language (AVDL) to realize a unified...
This project deals with the problems of utilization of mobile equipment working in the biomedicine field, particularly telemedicine. This field is relatively new; it focuses on the observation of life functions from a distance. Practically developing system works with an ECG sensor connected to mobile equipment, such as PDA/Embedded device, based on Microsoft Windows CE class operating system. The...
