A new version of FuXi (1.2) has been committed to mercurial [1] and uploaded to the Python Package Index [2]. The ReteAction wiki has been updated to reflect the new method added for registering externally defined actions to the production rule system. Below is changelist of modifications made. The most significant changes are 1) updates to the BFP reasoner so that it solves body literals in a rule in chunks that are converted into SPARQL queries that are evaluated at once (rather than at a tuple-at-a-time), 2) The handling of tokens by the RETE algorithm should now be a little more efficient, and 3) support for externally defined actions (as mentioned previously). - Extends the meta-interpreter with capabilities for collapsing chains of base predicate queries into a single SPARQL query - lazy evaluation of conjunction of multiple base predicates causes removal of certain meta interpreter rules - changed PartialInstanciation._generateBindings to use more efficient and concise algorithm - added FuXi.Network.Network.reportSize method which reports a summary of the RETE network (size of largest memories, etc.) - fix to deprecation warnings regarding use of md5 (use hashlib if available) - Added dict with set operations to FuXi.Rete.Util - added copy method to FuXi.Syntax.InfixOWL.BooleanClass - added registerReteAction method to Network instances There is only one [3] more step left before the top-down / SLD reasoner can be completely deprecated with the BFP reasoner As usual, comments / issues / etc. are welcome!
