Composing semantic services in open sensor-rich environments

Abstract

Networked sensing promises to drastically change the way people interact with their environments by providing rich contextual information in real time. Major challenges remain on how concurrent users program and control such environments at the application level. This paper summarizes our research efforts in automatically composing semantics services to fulfill declarative user queries in resource efficient ways. We also describe an example software platform, MSR Sense, which supports service abstraction, composition, and execution.
