Logic Programming as a Service
This work addresses the need for situated intelligence in pervasive systems by providing a service-oriented approach, though it appears incremental as it adapts existing logic programming methods to a new architectural context.
The paper tackles the challenge of enabling logic programming in pervasive intelligent systems by proposing Logic Programming as a Service (LPaaS), which reinterprets classical logic programming concepts into a distributed service model and demonstrates its implementation using distributed tuProlog engines.
New generations of distributed systems are opening novel perspectives for logic programming (LP): on the one hand, service-oriented architectures represent nowadays the standard approach for distributed systems engineering; on the other hand, pervasive systems mandate for situated intelligence. In this paper we introduce the notion of Logic Programming as a Service (LPaaS) as a means to address the needs of pervasive intelligent systems through logic engines exploited as a distributed service. First we define the abstract architectural model by re-interpreting classical LP notions in the new context; then we elaborate on the nature of LP interpreted as a service by describing the basic LPaaS interface. Finally, we show how LPaaS works in practice by discussing its implementation in terms of distributed tuProlog engines, accounting for basic issues such as interoperability and configurability.
