Vinay K. Chaudhri, Stijn Heymans, Michael Wessel, Son Cao Tran. Query Answering in Object Oriented Knowledge Bases in Logic Programming: Description and Challenge for ASP, in Workshop on ASP and Other Computing Paradigms, 2013.
Research on developing efficient and scalable ASP solvers can substantially benefit by the availability of data sets to experiment with. KB Bio 101 contains knowledge from a biology textbook, has been developed as part of Project Halo, and has recently become available for research use. KB Bio 101 is one of the largest KBs available in ASP and the reasoning with it is undecidable in general. We give a description of this KB and ASP programs for a suite of queries that have been of practical interest. We explain why these queries pose significant practical challenges for the current ASP solvers.
