Abstract
Given two documents A and B we define two mathematical notions: their resemblance r(A, B) and their containment c(A, B) that seem to capture well the informal notions of "roughly the same" and "roughly contained." The basic idea is to reduce these issues to set intersection problems that can be easily evaluated by a process of random sampling that can be done independently for each document. Furthermore, the resemblance can be evaluated using a fixed size sample for each document. This paper discusses the mathematical properties of these measures and the efficient implementation of the sampling process using Rabin (1981) fingerprints.

Using Sketches to Estimate Associations

TL;DR: This work generalizes sketches to estimate contingency tables and associations, using a maximum likelihood estimator to find the most likely contingency table given the sample, the margins (document frequencies) and the size of the collection.

De-duping URLs via rewrite rules

TL;DR: This work provides an efficient algorithm for mining and learning URL rewrite rules and shows that under mild assumptions, it is complete, i.e., the algorithm learns every URL rewrite rule that is correct, for an appropriate notion of correctness.

A Counterexample to Strong Parallel Repetition.

TL;DR: Feige et al. as discussed by the authors showed that the strong parallel repetition problem cannot be reduced to the strong Max-Cut problem, which is equivalent to the hardness of distinguishing between instances of MaxCut that are satisfiable from instances that are at most satisfiable.

Syntactic clustering of the Web

TL;DR: An efficient way to determine the syntactic similarity of files is developed and applied to every document on the World Wide Web, and a clustering of all the documents that are syntactically similar is built.

Min-Wise Independent Permutations

TL;DR: This research was motivated by the fact that such a family of permutations is essential to the algorithm used in practice by the AltaVista web index software to detect and filter near-duplicate documents.

Copy detection mechanisms for digital documents

TL;DR: This paper proposes a system for registering documents and then detecting copies, either complete copies or partial copies, and describes algorithms for such detection, and metrics required for evaluating detection mechanisms (covering accuracy, efficiency, and security).
