Experiments of E-Mail Filtering Method Based on Sender, Sentence Type, Existence of Time Expression, and Subject of Mail Contents

Filtering is a method of attaining only the wanted data and blocking the unwanted ones. Using this technology, the users can extract on the data that satisfy the query. As the previous studies use the single data, frequency of the data for example, it cannot be considered as the effective filtering method. What is needed is the effective technology that can process the electronic network documents such as the e-mail that contain the tags of various formats. This paper describes the study of extracting the information from the user query based on multi-attributes. It proposes a method of extracting the data such as the sender, text type, time limit syntax in the text, and title from the e-mail. It also describes the experiment to verify that multi-attribute based filtering method is more accurate than the existing filtering method.
