Abstract
Users usually need to learn more about the objects for their specific needs. However, it is inconvenient for users to acquire detailed information about the objects based on the abstract object descriptions. On the other hand, it might cost a lot of money and manpower for the object providers to attach comprensive and latest information on the objects. Taking the business card for example, it usually simply shows the abstact personal information and thus the card receiver might not be able to know the detailed information via the card. This research aims at developing an RFID-based model for extended information extraction (R-EIE) to search the extended information about the target object based on its identification and abstract descriptions. Based on the R-EIE concept, this research develops an RFID-based information extraction technology for business cards (R-EIE-BC) to assist the card receivers obtain the latest and comoprehensive information based on the contact information on cards. Before developing the R-EIE-BC methodology, this research analyzes the compoents for representing personal information. Based on the representation architecture of personal information, this research establishes a thesaurus to define the terms used to represent personal features. On the basis of the predefined thesaurus, an R-EIE-BC methodology and system is proposed. Using the R-EIE-BC system, the card receiver can maintain the contact information corresponding to each card in the database. As the card receiver acquires the identification of the target card by RFID reader, the system will search the extended information about the target person through the other information resources (e.g., Weblogs) based on the abstract information about him. The extended information is integrated with the original abstract information to represent the latest and comprehensive information about the target person. In brief, this research develops an RFID-based information extraction technology for business cards that can assists the card receivers to more efficiently acquire the latest and comprehensive profiles of the target person.
