Propositional Knowledge Base Revision and Minimal Change
- H. Katsuno, A. Mendelzon
- Mathematics, Computer Science
- Artif. Intell.
- 1 December 1991
Abstract The semantics of revising knowledge bases represented by sets of propositional sentences is analyzed from a model-theoretic point of view. A characterization of all revision schemes that… Expand

Finding Regular Simple Paths in Graph Databases
- A. Mendelzon, P. T. Wood
- Computer Science, Mathematics
- SIAM J. Comput.
- 1 July 1989
We consider the following problem: given a labelled directed graph G and a regular expression R, find all pairs of nodes connected by a simple path such that the concatenation of the labels along the… Expand
Extending query rewriting techniques for fine-grained access control
- S. Rizvi, A. Mendelzon, S. Sudarshan, P. Roy
- Computer Science
- SIGMOD '04
- 13 June 2004
Current day database applications, with large numbers of users, require fine-grained access control mechanisms, at the level of individual tuples, not just entire relations/views, to control which… Expand
GraphLog: a visual formalism for real life recursion
- Mariano P. Consens, A. Mendelzon
- Mathematics, Computer Science
- PODS '90
- 2 April 1990
We present a query language called GraphLog, based on a graph representation of both data and queries. Queries are graph patterns. Edges in queries represent edges or paths in the database. Regular… Expand
Database techniques for the World-Wide Web: a survey
- D. Florescu, A. Halevy, A. Mendelzon
- Computer Science
- SGMD
- 1 September 1998
The popularity of the World-Wide Web (WWW) has made it a prime vehicle for disseminating information. The relevance of database concepts to the problems of managing and querying this information has… Expand
Similarity-based queries for time series data
- Davood Rafiei, A. Mendelzon
- Computer Science
- SIGMOD '97
- 1 June 1997
We study a set of linear transformations on the Fourier series representation of a sequence that can be used as the basis for similarity queries on time-series data. We show that our set of… Expand

Testing implications of data dependencies
- D. Maier, A. Mendelzon, Y. Sagiv
- Computer Science
- TODS
- 1 December 1979
Presented is a computation method—the chase—for testing implication of data dependencies by a set of data dependencies. The chase operates on tableaux similar to those of Aho, Sagiv, and Ullman. The… Expand
