从大序列数据中寻找序列模式

Finding Sequential Patterns from Large Sequence Data

Mahdi Esmaeili, Fazekas Gabor

摘要:

数据采掘是从大量数据中发现有趣模式的任务。有许多数据采掘任务,如分类,聚类,关联规则挖掘,序列模式挖掘。序列模式挖掘发现在某些序列中频繁出现的数据项集。序列模式挖掘是从序列数据库中提取频繁序列的一种方法,是近年来数据采掘研究的热点之一,因为它是许多应用的基础,如:网络用户分析、股票趋势预测、DNA序列分析、从自然语言文本中发现语言或语言模式、利用症状历史预测某种疾病等。应用的多样性可能不可能将单个序列模式模型应用于所有这些问题。每个应用程序可能需要一个独特的模型和解决方案。近年来,许多研究项目建立了有意义的序列模式模型和挖掘这些模式的有效算法。本文从理论上简要概述了三种类型的序列模式模型。

英文摘要:

Data mining is the task of discovering interesting patterns from large amounts of data. There are many data mining tasks, such as classification, clustering, association rule mining, and sequential pattern mining. Sequential pattern mining finds sets of data items that occur together frequently in some sequences. Sequential pattern mining, which extracts frequent subsequences from a sequence database, has attracted a great deal of interest during the recent data mining research because it is the basis of many applications, such as: web user analysis, stock trend prediction, DNA sequence analysis, finding language or linguistic patterns from natural language texts, and using the history of symptoms to predict certain kind of disease. The diversity of the applications may not be possible to apply a single sequential pattern model to all these problems. Each application may require a unique model and solution. A number of research projects were established in recent years to develop meaningful sequential pattern models and efficient algorithms for mining these patterns. In this paper, we theoretically provided a brief overview three types of sequential patterns model.
