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.

Raven: a de novo genome assembler for long reads

TL;DR: New methods for the improvement of long-read de novo genome assembly incorporated into a straightforward tool called Raven, which is one of two fastest, it reconstructs the sequenced genome in the least amount of fragments, has better or comparable accuracy, and maintains similar performance for various genomes.

Approximate Nearest Neighbor Search in High Dimensions

TL;DR: The nearest neighbor problem as mentioned in this paper is defined as follows: given a set of points in some metric space, build a data structure that, given any point $q, returns a point in the set $P$ that is closest to $q$ (its "nearest neighbor" in $P), which is then used to find the nearest neighbor without computing all distances between the points.

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).
