Koko: A System for Scalable Semantic Querying of Text
Summary: Koko is a declarative semantic-query system combining surface syntax, dependency-tree structure, evidence aggregation, and linguistic-variation tolerance for scalable text extraction. An interactive interface visualizes parses, token/query correspondences, and extraction scores. (summarized by gpt-5.6-luna on Jul 24 2026)
