Fully compressed suffix trees [PDF]

open access: yesACM Transactions on Algorithms, 2008
Suffix trees are by far the most important data structure in stringology, with a myriad of applications in fields like bioinformatics and information retrieval. Classical representations of suffix trees require Θ( n log n ) bits of space, for a string of size n .

Efficient computation of absent words in genomic sequences [PDF]

open access: yesBMC Bioinformatics, 2008
Background Analysis of sequence composition is a routine task in genome research. Organisms are characterized by their base composition, dinucleotide relative abundance, codon usage, and so on.

Converting suffix trees into factor/suffix oracles [PDF]

open access: yesJournal of Discrete Algorithms, 2008
Several methods to compress suffix trees were defined, most of them with the aim of obtaining compact (that is, space economical) index structures. Besides this practical aspect, a compression method can reveal structural properties of the resulting data structure, allowing a better understanding of it and a better estimation of its performances.

Weighted Ancestors in Suffix Trees [PDF]

open access: yes, 2014
The classical, ubiquitous, predecessor problem is to construct a data structure for a set of integers that supports fast predecessor queries. Its generalization to weighted trees, a.k.a. the weighted ancestor problem, has been extensively explored and successfully reduced to the predecessor problem.

Intent Arabic text categorisation based on different machine learning and term frequency

open access: yesIET Networks, EarlyView., 2022
Abstract The complexity of Internet network configurations has made managing networks a complicated undertaking. Intent‐Based Networking (IBN) is a potential solution to this issue. In contrast to conventional networks, where a concrete description of the settings typically conveys a network administrator's goal kept on each device, an administrator's ...

Average profiles, from tries to suffix-trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
We build upon previous work of Fayolle (2004) and Park and Szpankowski (2005) to study asymptotically the average internal profile of tries and of suffix-trees. The binary keys and the strings are built from a Bernoulli source $(p,q)$.

Sliding Suffix Tree [PDF]

open access: yesAlgorithms, 2018
We consider a sliding window W over a stream of characters from some alphabet of constant size. We want to look up a pattern in the current sliding window content and obtain all positions of the matches. We present an indexed version of the sliding window, based on a suffix tree.

Analysis of the multiplicity matching parameter in suffix trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
In a suffix tree, the multiplicity matching parameter (MMP) $M_n$ is the number of leaves in the subtree rooted at the branching point of the $(n+1)$st insertion.

A tight upper bound on the size of the antidictionary of a binary string [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
A tight upper bound of the size of the antidictionary of a binary string is presented. And it is shown that the size of the antidictionary of a binary sting is always smaller than or equal to that of its dictionary.

Non-Overlapping LZ77 Factorization and LZ78 Substring Compression Queries with Suffix Trees

open access: yesAlgorithms, 2021
We present algorithms computing the non-overlapping Lempel–Ziv-77 factorization and the longest previous non-overlapping factor table within small space in linear or near-linear time with the help of modern suffix tree representations fitting into ...
