Temporal Data MiningTemporal data mining deals with the problem of mining knowledge from temporal data, which can be either symbolic sequences or numerical time series. Both types of temporal data have been intensively studied in data mining and statistics.
Development of Methods for Storing, Accessing, and Visualizing Temporal Patterns for Selecting the Best Patterns.
In this era of information, one of the major problems frequently encountered by
companies is how to process their data into information that provides benefits to the company. In order to face this challenge many techniques have been developed to find the information from the data. This information is usually presented in the form of patterns or rules. However, most of these techniques focus on the discovery of non-temporal patterns from non-temporal data. In reality, much of the data owned by the company is in the form of temporal data. Although several methods for discovering patterns from temporal data have been developed these techniques are still weak in terms of post-processing the discoverd patterns. In order to discover the best pattern, post-processing role is very important because from thousands of patterns generated by data mining algorithms only a small part of them is useful, and this can only be identified through post-processing.
Selecting the pattern from thousands of temporal patterns is not easy work. Because of that, in this research we develop a mechanism that can facilitate users in selecting the best temporal patterns, especially sequential patterns. Our research has developed a method for storing and accessing sequential patterns efficiently. It has also developed a visualization method that allows a group of sequential pattern to be displayed in the form of tree that can be easily used by the user for selecting the pattern.
