DBMS with probabilistic model • Probabilities and uncertainty taken seriously as foundation for the database model – not an add-on • old idea but never taken seriously • e.g. Fuhr’s Probabilistic Datalog • Probabilistic retrieval model, probabilistic schema, uncertain queries, learning, appropriate data structures, etc.

  2. IR queries for DBMS • Not the same as NL queries work done in 80s • Take a NL query, apply it to a DBMS, determine what type of answer can be provided • may be fact-type answer (QA) • may be ranked tuples (IR) • Useful for distributed, heterogeneous search • e.g. Hidden Web • should not require wrappers
