Beyond Memorization: Distinguishing Between Pattern-Based and Epistemic Reasoning in LLMs Using Epistemic Puzzles
Adi Gabay, Gabriel Stanovsky, Liat Peterfreund
Epistemic reasoning requires agents to infer the state of the world from partial observations and information about other agents' knowledge. Prior work evaluating LLMs on epistemic…
Database Theory in Action: From Inexpressibility to Efficiency in GQL's Order-Constrained Paths
Hadar Rotschield, Liat Peterfreund
Pattern matching of core GQL, the new ISO standard for querying property graphs, cannot check whether edge values are increasing along a path, as established in recent work. We pre…
On the Expressiveness of Languages for Querying Property Graphs in Relational Databases
Hadar Rotschield, Liat Peterfreund
SQL/PGQ is the emerging ISO standard for querying property graphs defined as views over relational data. We formalize its expressive power across three fragments: the read-only cor…
Towards Cross-Model Efficiency in SQL/PGQ
Hadar Rotschield, Liat Peterfreund
SQL/PGQ is a new standard that integrates graph querying into relational systems, allowing users to freely switch between graph patterns and SQL. Our experiments show performance g…
Rel: A Programming Language for Relational Data
Molham Aref, Paolo Guagliardo, George Kastrinis +12
From the moment of their inception, languages for relational data have been described as sublanguages embedded in a host programming language. Rel is a new relational language whos…
GQL and SQL/PGQ: Theoretical Models and Expressive Power
Amélie Gheerbrant, Leonid Libkin, Liat Peterfreund +1
SQL/PGQ and GQL are very recent international standards for querying property graphs: SQL/PGQ specifies how to query relational representations of property graphs in SQL, while GQL…
