Treo: Schema-agnostic queries over databases
Treo is a Semantic Search and Question Answering System for Databases. Treo is designed to cope with the Big Data vision of handling very heterogeneous (schemaless) databases, a scenario where it becomes unfeasible for data consumers to understand the representation of the data in order to query the database.
Schema-agnostic/vocabulary-independent natural language queries Designed to work with very heterogeneous databases Comprehensive semantic matching based on distributional semantics Supports queries over Linked Data/RDF
