k-step Reachability Query Processing on Label-constrained Graph [PDF]
The k-step reachability query processing on label-constrained graph is used to answer whether there is a path with a length not greater than k between two points and the labels on this path are in the specified label set.The k-step reachability query ...

PIR with Compressed Queries and Amortized Query Processing [PDF]
Private information retrieval (PIR) is a key building block in many privacy-preserving systems. Unfortunately, existing constructions remain very expensive. This paper introduces two techniques that make the computational variant of PIR (CPIR) more efficient in practice.

Skew in parallel query processing [PDF]
We study the problem of computing a conjunctive query q in parallel, using p of servers, on a large database. We consider algorithms with one round of communication, and study the complexity of the communication. We are especially interested in the case where the data is skewed, which is a major challenge for scalable parallel query processing.
