Pervasive applications rely on data captured from the physical world through sensor devices. Data provided by these devices, however, tend to be unreliable. The data must, therefore, be cleaned before an application can make use of them, leading to additional complexity for application development and deployment. Here we present (), a framework for building sensor data cleaning infrastructures for use in pervasive applications. is designed as a pipeline using declarative cleaning mechanisms based on spatial and temporal characteristics of sensor data. We demonstrate effectiveness and ease of use through three real-world scenarios. [ABSTRACT FROM AUTHOR] |
