Optimal Trust Network Analysis with Subjective Logic
Trust network analysis with subjective logic (TNA-SL) simplifies complex trust graphs into series-parallel graphs by removing the most uncertain paths to obtain a canonical graph...

The Expressive Rate of Constraints
In reasoning tasks involving logical formulas, high expressiveness is desirable, although it often leads to high computational complexity. We study a simple measure of expressiven...

Untestable Properties Expressible with Four First-Order Quantifiers
Abstract. In property testing, the goal is to distinguish between structures that have some desired property and those that are far from having the property, after examining only a...

Worst-case Optimal Conjunctive Query Answering for an Expressive Description Logic without Inverses
Answering conjunctive queries (CQs) has been recognized as a key task for the usage of Description Logics (DLs) in a number of applications, and has thus been studied by many auth...
