Abstract Details

2001, MS, University of Cincinnati, Engineering : Computer Science.
A document management system, called SDMS (Signature-file Document Management System), has been designed and implemented. This system was designed based on the signature file method to store documents in a database file and to retrieve them according to the user queries. We implemented an application, Email Organizer, based on the SDMS. This system will be useful for individuals as well as organizations where their emails need to be stored, indexed, categorized and then retrieved efficiently based on the content. User queries can be formulated by using keywords from the text that are interrelated by the Boolean operators AND, and OR. A novel algorithm based on linear feedback shift registers (LFSR) has also been developed and implemented for generating word signatures. The objective of incorporating this approach is to reduce its false drop ratio and to improve its signature generation speed. This algorithm has been compared with the hashing functions for performance. Experiments revealed that the LFSR algorithm is comparable to the hashing algorithm in terms of signature generation time and false drop ratio.
