Exploring Parallelization of Conjunctive Branches in Tableau-Based Description Logic Reasoning

Kejia Wu, Volker Haarslev
2013 International Workshop on Description Logics  
Multiprocessor equipment is cheap and ubiquitous now, but users of description logic (DL) reasoners have to face the awkward fact that the major tableau-based DL reasoners can make use only one of the  ...  In this work, we present an algorithm to process conjunctive branches in parallel and address the key implementation aspects of the algorithm.  ...  Unfortunately, few such advances have been achieved for tableau-based Description Logic (DL) reasoning, which is the dominant method adopted by the major DL reasoning systems.  ...

Parallel Computation Techniques for Ontology Reasoning [chapter]

Jürgen Bock
2008 Lecture Notes in Computer Science  
As current reasoning techniques are not designed for massive parallelisation, usage of parallel computation techniques in reasoning establishes a major research problem.  ...  I will propose two possibilities of applying parallel computation techniques to ontology reasoning: parallel processing of independent ontological modules, and tailoring the reasoning algorithms to parallel  ...  chunks of computation (e.g. branches in a tableau).  ...

Bridging the Gap between Tableau and Consequence-Based Reasoning

Yevgeny Kazakov, Pavel Klinov
2014 International Workshop on Description Logics  
We present a non-deterministic consequence-based procedure for the description logic ALCHI.  ...  This is similar to tableau-based procedures, for which an ontology is inconsistent if every expansion of the tableau eventually results in a clash.  ...  Introduction and Motivation Consequence-based and tableau-based methods are two well-known approaches to reasoning in Description Logics (DLs).  ...

Converting Instance Checking to Subsumption: A Rethink for Object Queries over Practical Ontologies

Jia Xu, Patrick Shironoshita, Ubbo Visser, Nigel John, Mansur Kabuka
2015 International Journal of Intelligence Science  
Efficiently querying Description Logic (DL) ontologies is becoming a vital task in various data-intensive DL applications.  ...  With independence between computed MSC's, scalability for query answering can also be achieved by distributing and parallelizing the computations.  ...  Acknowledgements This work is partly supported by grant # R44GM097851 from the National Institute of General Medical Sciences, part of the U.S. National Institutes of Health (NIH).  ...

Handling Non-determinism with Description Logics using a Fork/Join Approach

Jocelyne Faddoul, Wendy MacCaull
2015 International Journal of Networking and Computing  
The rise of such powerful execution environments calls for new parallel and distributed Description Logics (DLs) reasoning algorithms.  ...  We implement a fork/join parallel framework into our tableau-based algebraic reasoner, which handles qualified cardinality restrictions and nominals using in-equation solving.  ...  Parallelizing Non-determinism Tableau-based reasoning has been the most common choice for Description Logics tools.  ...

Implementation of a Tableau-based Satisfiability Checker for HS3

Emilio Muñoz-Velasco, Guido Sciavicco, Ionel Eduard Stan
2017 Italian Conference on Theoretical Computer Science  
In this paper we describe an implementation of a tableau-based satisfiability checker for HS3 interpreted in the class of all finite linear orders.  ...  Although there exist several decidable fragments of Halpern and Shoham's interval temporal logic HS, the computational complexity of their satisfiability problem tend to be generally high.  ...  Conclusions In this paper we have described an efficient implementation of a tableau-based reasoner for the interval temporal logic HS3, whose finite satisfiability problem had been shown to be PSpace-complete  ...

A New Rule for LTL Tableaux

Mark Reynolds
2016 Electronic Proceedings in Theoretical Computer Science  
In this paper, we introduce a novel style of tableau rule which supports a new simple traditional-style tree-shaped tableau for LTL. We prove that it is sound and complete.  ...  Propositional linear time temporal logic (LTL) is the standard temporal logic for computing applications and many reasoning techniques and tools have been developed for it.  ...  It is also unique in allowing separate parallel development of branches.  ...
