Score: 8.0/10 (Innovation: 8, Technical: 8, Documentation: 9, Utility: 7)

Reckoner is a semantic query workbench that allows domain experts to query structured data using plain English-like terms (who, what, when, where, why, how) instead of SQL or column names. Its innovative approach combines semantic normalization, boolean routing, and a planner (Portolan) to deliver fast, traceable results, making it uniquely accessible for non-technical users working with datasets like record collections or legal databases.

Target audience: data engineers, domain experts, analysts
