On the resemblance and containment of documents
TLDR
The basic idea is to reduce these issues to set intersection problems that can be easily evaluated by a process of random sampling that could be done independently for each document.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.read more

Tracking Web spam with HTML style similarities
TL;DR: This work study and compare several HTML style similarity measures based on both textual and extra-textual features in HTML source code and proposes a flexible algorithm to cluster a large collection of documents according to these measures.

Delta compression after identity deduplication
TL;DR: In this article, the identity deduplication is disclosed and a first data segment is determined to be identical to a first previous data segment, and a second data segment was determined not to be similar to a third previous segment.
Consistent Weighted Sampling
TL;DR: An ecient procedure for sampling representatives from a weighted set such that for any weightings S and T, the probability that the two choose the same sample is the Jacard similarity.

An improved plagiarism detection scheme based on semantic role labeling
TL;DR: The method significantly outperforms the modern methods for plagiarism detection in terms of Recall, Precision and F-measure and weighting for each argument generated by SRL to study its behaviour is introduced.

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.

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).
