Applications of String Mining Techniques in Text Analysis

The focus of this project is on the algorithms and data structures used in string mining and their applications in bioinformatics, text mining and information retrieval. More specific, it studies the use of suffix trees and suffix arrays for biological sequence analysis, and the algorithms used for approximate string matching, both general ones and specialized ones used in bioinformatics, like ...

Adaptive Approximate Record Matching

Typographical data entry errors and incomplete documents, produce imperfect records in real world databases. These errors generate distinct records which belong to the same entity. The aim of Approximate Record Matching is to find multiple records which belong to an entity. In this paper, an algorithm for Approximate Record Matching is proposed that can be adapted automatically with input error...

On Approximate String Matching of Unique Oligonucleotides

The current research considers the approximate string matching search for important subsequences from DNA sequences, which is essential for numerous bioinformatics computation tasks. We tested several approximate string matching algorithms and furthermore developed one for DNA data. Run times of the algorithms are important, since the amount of data is very large.

Approximate String Matching with Reduced Alphabet

We present a method to speed up approximate string matching by mapping the factual alphabet to a smaller alphabet. We apply the alphabet reduction scheme to a tuned version of the approximate Boyer– Moore algorithm utilizing the Four-Russians technique. Our experiments show that the alphabet reduction makes the algorithm faster. Especially in the k-mismatch case, the new variation is faster tha...

A Lossy Data Compression Based on String Matching: Preliminary Analysis and Suboptimal Algorithms

A practical suboptimal algorithm (source coding) for lossy (non-faithful) data compression is discussed. This scheme is based on an approximate string matching, and it naturally extends lossless (faithful) Lempel-Ziv data compression scheme. The construction of the algorithm is based on a careful probabilistic analysis of an approximate string matching problem that is of its own interest. This ...
