ABSTRACT
This research project involved the creation of an information retrieval (IR) system, called the Information Retrieval system for Thai Revenue Codes (TIRReC). Revenue Codes (RC) are significant and necessary for the work of Revenue Departments (RD), and also, they can enable the taxpayer to understand the taxation process better. The goal was to improve the performance of the current RC searching system, which is a web-based application running on the intranet of RD. In contrast to the current system, TIRReC helps users retrieve the relevant RC and support them when needed. Furthermore, it also helps reduce the browsing time when the RC is retrieved. For query expression, many types of expressions can be applied. There is keyword searching, which involves the input of a query as a Boolean expression or a natural language expression, vector expression, which allows us to specify the important level of each keyword, and exact string matching. With the retrieved RC, one can perform further searching in order to reduce the number of output results. The result set of retrieved RCs will be ranked according to their relevancies to user query. This research project introduced modern information retrieval techniques to be used in the TIRReC system. The experimental results show that TIRReC performed satisfactorily and can improve the performance of RC retrieval system.
