Analyzing State Sequences with Probabilistic Suffix Trees: The PST R Package

open access: yesJournal of Statistical Software, 2016
This article presents the PST R package for categorical sequence analysis with probabilistic suffix trees (PSTs), i.e., structures that store variable-length Markov chains (VLMCs).

Representing the suffix tree with the CDAWG

open access: yesCoRR, 2017
Given a string $T$, it is known that its suffix tree can be represented using the compact directed acyclic word graph (CDAWG) with $e_T$ arcs, taking overall $O(e_T+e_{\overline{T}})$ words of space, where ${\overline{T}}$ is the reverse of $T$, and supporting some key operations in time between $O(1)$ and $O(\log{\log{n}})$ in the worst case.

Faster repetition-aware compressed suffix trees based on Block Trees [PDF]

open access: yes, 2022
The suffix tree is a fundamental data structure in stringology, but its space usage, though linear, is an important problem in applications like Bioinformatics.

Construction of distributed suffix trees

open access: yesТехнічна інженерія
The paper addresses the problem of parallel suffix tree construction over large text arrays without the use of cluster infrastructure. The evolution of relevant algorithms is analysed – from the single-threaded methods of Weiner, McCreight, and Ukkonen ...

Structure and Sequence Aligned Code Summarization with Prefix and Suffix Balanced Strategy

open access: yesEntropy, 2023
Source code summarization focuses on generating qualified natural language descriptions of a code snippet (e.g., functionality, usage and version). In an actual development environment, descriptions of the code are missing or not consistent with the code

Doubts on Irish Iubhar 'Yew Tree' and Eburacum or York [PDF]

open access: yesВопросы ономастики, 2019
York, a cathedral city in the north of England, was the Eburacum or Colonia Eburacensis of Roman Britain. Its name has usually been explained from Irish iubhar ‘yew tree’ (or alternatively from Welsh efwr ‘hogweed’) and so ‘place where yew trees grow ...

BuST-Bundled Suffix Trees [PDF]

open access: yes, 2006
We introduce a data structure, the Bundled Suffix Tree (BUST), that is a generalization of a Suffix Tree (ST). To build a BuST we use an alphabet Σ together with a non-transitive relation ≈ among its letters. Following the path of a substring β within a BUST, constructed over a text α of length n, not only the positions of the exact occurrences of β in

Suffix trees for very large genomic sequences [PDF]

open access: yes, 2009
A suffix tree is a fundamental data structure for string search-ing algorithms. Unfortunately, when it comes to the use of suffix trees in real-life applications, the current methods for constructing suffix trees do not scale for large inputs.

Linear-Time Text Compression by Longest-First Substitution

open access: yesAlgorithms, 2009
We consider grammar-based text compression with longest first substitution (LFS), where non-overlapping occurrences of a longest repeating factor of the input text are replaced by a new non-terminal symbol.
