Similarity Identification Based on Word Trigrams Using Exact String Matching Algorithms

open access: yesIntensif: Jurnal Ilmiah Penelitian Teknologi dan Penerapan Sistem Informasi, 2022
Several studies regarding excellent exact string matching algorithms can be used to identify similarity, including the Rabin-Karp, Winnowing, and Horspool Boyer-Moore algorithms.

Ultra-high throughput string matching for deep packet inspection [PDF]

open access: yes, 2010
Deep Packet Inspection (DPI) involves searching a packet's header and payload against thousands of rules to detect possible attacks. The increase in Internet usage and growing number of attacks which must be searched for has meant hardware acceleration ...

Compressibility-Aware Quantum Algorithms on Strings [PDF]

open access: yes, 2023
Sublinear time quantum algorithms have been established for many fundamental problems on strings. This work demonstrates that new, faster quantum algorithms can be designed when the string is highly compressible. We focus on two popular and theoretically

Consistent Unsupervised Estimators for Anchored PCFGs

open access: yesTransactions of the Association for Computational Linguistics, 2020
Learning probabilistic context-free grammars (PCFGs) from strings is a classic problem in computational linguistics since Horning ( 1969 ). Here we present an algorithm based on distributional learning that is a consistent estimator for a large class of ...

Adaptive text mining: Inferring structure from sequences [PDF]

open access: yes, 2004
Text mining is about inferring structure from sequences representing natural language text, and may be defined as the process of analyzing text to extract information that is useful for particular purposes.

Rotation of bits: a classical and quantum perspective

open access: yesJournal of Electrical Systems and Information Technology, 2021
Bit rotation is an operation similar to shift except that the bits that fall off at one end are put back to the other end. In left rotation, the bits that fall off at left end are put back at right end.

Small Longest Tandem Scattered Subsequences

open access: yesScientific Annals of Computer Science, 2021
We consider the problem of identifying tandem scattered subsequences within a string. Our algorithm identifies a longest subsequence which occurs twice without overlap in a string.

Hide and Mine in Strings: Hardness and Algorithms [PDF]

open access: yes2020 IEEE International Conference on Data Mining (ICDM), 2020
We initiate a study on the fundamental relation between data sanitization (i.e., the process of hiding confidential information in a given dataset) and frequent pattern mining, in the context of sequential (string) data. Current methods for string sanitization hide confidential patterns introducing, however, a number of spurious patterns that may harm ...

Hardness of Detecting Abelian and Additive Square Factors in Strings [PDF]

open access: yes, 2021
We prove 3SUM-hardness (no strongly subquadratic-time algorithm, assuming the 3SUM conjecture) of several problems related to finding Abelian square and additive square factors in a string.

Computing Maximal Lyndon Substrings of a String

open access: yesAlgorithms, 2020
There are two reasons to have an efficient algorithm for identifying all right-maximal Lyndon substrings of a string: firstly, Bannai et al. introduced in 2015 a linear algorithm to compute all runs of a string that relies on knowing all right-maximal ...
