v0.7.0

Added

• patterns.is_wildcard().
• Base class hypergraph.memory.keyvalue.KeyValue for key-value hypergraph databases, removing redundant code between LevelDB and SQLite.
• Tests for LevelDB (only the SQLite Hypergraph implementation was being directly tested).
• Hyperedge.is_unordered_pattern().
• Functional pattern: any.
• Parser-level inference of coreferences between proper nouns.
• Parser.parse_and_add() now adds token information to the main edge of a sentence: the attribute 'tokens' contains the list of tokens and 'tok_pos' a structure with the token position for each atom in the edge.
• Post-processing step improves parser.
• Hypergraph.get_attributes().

Changed

• Entire project is now in pure Python
• Python >=3.10 now required.
• Hypergraph.search(), .match() and .count() now working with functional patterns and argument role matching.
• Fixed bug on match_pattern(), variables were not correctly matched when argument roles were specified past the first position in an atoms functional pattern.
• Simplified default systems connectors (breaks hypergraph DB backwards compatibility).
• max_text argument in parser.parse_and_add().
• Matches from patterns with repeated variables are collected in lists.

Removed

• graphbrain.logic obsolete module.
• LevelDB backend
