| Abstract | A THAI and ENGLISH Information Retrieval (TEIR) system is developed by using an
extended double-array as the retrieval table and a relational database management system
(RDBMS) to implement the posting file. Extended double-arrays for digital search tree are
introduced and a new updating algorithm presented. The new algorithm has many advantages over
the original one: faster insertion time, support of up to 2 GB of nodes, and retrieval of keywords
in sequence. The advantages of using RDBMS to implement posting files are that the file system
can easily be ported to other computer systems and one has better file management.
A major limitation of IR system when dealing with THAI text is that it cannot retrieve text
using THAI phrases. Current THAI IR systems can retrieve text only by employing some specific
THAI keywords. The TEIR presents 2 methods to correct the problem of retrieving text using
THAI phrases. |
