Data Uncertainty Model for Mashup
نویسندگان
چکیده
Mashup is a new kind integration application and users can compose related services as components to build new application—the mashups. Now the services on the web have different degrees of data uncertainty, including data error, stale data, and improper data processing and so on. We provide a data uncertainty model for mashup component which is assessed in the space of the homogeneous components that have the same functionality, and then we give the uncertainty computation mechanism of mashups based on the data uncertainty of mashup components and the computation sequence for different composition relationships. Keywords-component; mashup; data uncertainty

Discovery of Service HyperLinks with User Feedbacks for Situational Data Mashup
Discovery of loose data linkages between data services can help on-demand Web data integration in accordance with situation changes. However, we met the uncertainty challenge when discovering such data linkages with current automatic matchers. To handle the uncertainty problem, this paper develops a synthesized matching algorithm to combine the matching results from multiple automatic matchers ...
متن کاملSensormash: Exploring System Fidelity through Sensor Mashup
Context-aware services are driven by sensed data from both real and virtual worlds. Building effective pervasive systems involves administration and fine tuning of sensors toward optimal operation. Difficulties arise because sensors are prone to inaccuracies through miscalibration, malfunction and component limitations. Any incorrect values of sensed data need to be accounted for and dealt with...
متن کاملMashup Model and Verification Using Mashup Processing Network
Mashups are defined to be lightweight Web applications aggregating data from different Web services, built using ad-hoc composition and being not concerned with long term stability and robustness. In this paper we present a pattern based approach, called Mashup Processing Network (MPN). The idea is based on Event Processing Network and is supposed to facilitate the creation, modeling and the ve...
متن کاملLet It Flow: Building Mashups with Data Processing Pipelines
Mashups are a new kind of interactive Web application, built out of the composition of two or more existing Web service APIs and data sources. Whereas “pure” mashups are built relying entirely on the Web browser as a platform for integration at the presentation layer, this approach is not always feasible and part of the mashup integration logic must be deployed on the Web server instead. In the...
متن کاملRecommending Optimal API Orchestration with Mining Frequent Mashup Patterns
As more and more organizations publish their data or services through Open APIs on the Internet, mashup applications have captured a lot of attention in recent years. However, as the number and categories of Open APIs grow rapidly, efficiently creating optimal mashup applications becomes a crucial issue for making the technology of mashup more applicable. In this work, we present a Mashup Direc...
