Current efficient planners employ an informed search guided by a heuristic function that is quite expensive to compute. Thus, ordering nodes in the search tree becomes a key issue,...
Abstract. Description Logics are a family of class based knowledge representation formalisms characterised by the use of various constructors to build complex classes from simpler ...
Abstract—A growing number of applications start using Semantic Web technologies. The base concept in this technology is the use of ontologies, allowing first-order logic reasoni...
—This paper describes a model of a hierarchical, heterogeneous knowledge-base. The proposed model consists of an associative level that is implemented by a Kanerva-like sparse di...
In [6], Gallager introduces a family of codes based on sparse bipartite graphs, which he calls low-density parity-check codes. He suggests a natural decoding algorithm for these c...
