Based on the initial testing, using the IR approach in
storing and retrieving Thai-text structured data has the
advantages of having better response time and result
accuracy over the DBMS. The improvement in
response time is particularly critical when querying
fields storing long text strings. The improvement in
result accuracy is particularly critical when using short
query terms which can appear in text string of some
There are some disadvantages of using the IR
approach. First, retrieval performance of the IR
technique described in this paper partly depends on
dictionary, which affects performance of word
segmentation. More comprehensive dictionary will
result in better performance of word segmentation,
other terms.
