COROR: A COmposable Rule-Entailment Owl Reasoner for Resource-Constrained Devices

Design and validation of a light-weight reasoning system to support remote health monitoring applications

“…Second, the existing systems proposed in (Ali and Kiefer, 2009;Gu et al, 2007;Kim et al, 2010;Tai et al 2011;Motik et al 2012) do not make their code accessible to be downloaded and tested on mobile devices for a comparative performance evaluation. Differently, Bossam (Jang and Sohn, 2004) makes its implementation freely available, but it supports only J2ME Connected Device Configuration, so resulting incompatible to be ported on a lot of mobile devices only compliant with CLDC 1.1 or Android-based.…”

“…In the following, only mobile reasoning systems (Ali and Kiefer, 2009;Gu et al, 2007;Kim et al, 2010;Lorecarra, 2009;Tai et al 2011;Motik et al 2012) expressly devised as rule-based, i.e. having if-then rules as their basic unit of computation, have been analyzed, since mostly suitable to deal with declarative and procedural knowledge.…”

“…Moreover, it offers a RETE-based rule engine with some basic mechanisms to reduce the memory usage by optimizing the handling of data instances. However its RETE implementation is not optimized and, therefore, it is likely that inefficient pattern matches may occur if rules are not tuned by experts (Tai et al, 2011).…”

“…COROR (Tai et al 2011) is a COmposable Rule-entailment Owl Reasoner for resource-constrained devices. It makes use of two composition algorithms, i.e.…”

“…There are some semantic-enabled proposals supporting these two typologies of reasoning (Ali and Kiefer, 2009;Gu et al, 2007;Kim et al, 2010;Lorecarra, 2009;Jang and Sohn, 2004;Tai et al, 2011;Motik et al, 2012). Nonetheless, from a theoretical point of view, their performance on mobile devices and under a realistic RHM scenario is unlikely to achieve acceptable levels with reference to responsiveness and memory consumption, since strongly influenced by various factors, such as the reasoning algorithms used and the data scale.…”
