Efficient mining of frequent XML query patterns with repeating-siblings
Information and Software Technology, 2008A recent approach to improve the performance of XML query evaluation is to cache the query results of frequent query patterns. Unfortunately, discovering these frequent query patterns is an expensive operation. In this paper, we develop a two-pass mining algorithm 2PXMiner that guarantees the discovery of frequent query patterns by scanning the ...

Commercial detection by mining maximal repeated sequence in audio stream
2011 IEEE International Conference on Multimedia and Expo, 2011Efficient detection of commercial is an important topic for many applications such as commercial monitoring, market investigation. This paper reports an unsupervised technique of discovering commercial by mining repeated sequence in audio stream. Compared with previous work, we focus on solving practical problems by introducing three principles of ...

Post, Mine, Repeat: social media data mining becomes ordinary
Information, Communication & Society, 2017In times of datafication, we are producing more and more social media (and other) data. But this opens up new avenues for it to be collected, stored, classified, analysed, and disseminated: for it ...

An Automated Matrix Profile for Mining Consecutive Repeats in Time Series
2018A key application of wearable sensors is remote patient monitoring, which facilitates clinicians to observe patients non-invasively, by examining the time series of sensor readings. For analysis of such time series, a recently proposed technique is Matrix Profile (MP).

Large Scale Analysis of Small Repeats via Mining of the Human Genome
2009 20th International Workshop on Database and Expert Systems Application, 2009Small repetitive sequences, called tandem repeats, are abundant throughout the human genome, both in coding and in non-coding regions. Their role is still mostly unknown, but at least 20 of those repetitive sequences have been related to neurodegenerative disorders. The mutational process that is the basis of these disorders is not yet fully understood.

Incrementally Mining Recently Repeating Patterns over Data Streams
2009Repeating patterns represent temporal relations among data items, which could be used for data summarization and data prediction. More and more data of various applications is generated as a data stream. Based on time sensitive concern, mining repeating patterns from the whole history data sequence of a data stream does not extract the current trend of

MINING APPROXIMATE REPEATING PATTERNS FROM SEQUENCE DATA WITH GAP CONSTRAINTS
Computational Intelligence, 2011The rapid increase of available DNA, protein, and other biological sequences has made the problem of discovering meaningful patterns from sequences an important task for Bioinformatics research. Among all types of patterns defined in the literature, the most challenging one is to find repeating patterns with gap constraints.

A novel approach for mining cyclically repeated patterns with multiple minimum supports
Applied Soft Computing, 2015We consider the mining of cyclically repeated patterns (CRPs) with skewed repetition distribution.The problem of mining CRPs with multiple minimum supports is formally defined.An efficient method is developed to discover significant CRPs.Our approach is efficient and can discover valuable CRPs in all tests.

An Efficient Approach for Mining Top-K Fault-Tolerant Repeating Patterns
2006In this paper, an efficient strategy for mining top-K non-trivial fault-tolerant repeating patterns (FT-RPs in short) with lengths no less than min_len from data sequences is provided. By extending the idea of appearing bit sequences, fault-tolerant appearing bit sequences are defined to represent the locations where candidate patterns appear in a data

Mining Knowledge from Repeated Co-Occurrences: DIOGENE at TREC 2002. [PDF]
, 2002 This paper presents a new version of the DIOGENE Question Answering (QA) system developed at ITC-Irst. With respect to our first participation to the TREC QA main task (TREC-2001), the system presents both improvements and extensions. On one hand, significant improvements rely on the substitution of basic components (e.g. the search engine and the tool
