Both approaches are relevant for m-commerce
because they save time in browsing and searching, which is very much required by
mobile users who are always on the move. Thus, by combining keyword queries
with ontology, it is possible to achieve a better and more effective query formation.
Before ontology terms are accessed to form the queries, there will be a keyword
search to find the required ontology term. For example, ps2 can be hidden in the
node ???mouse??? when presented in the ontology. The user will not be able to know
where ps2 can be found intuitively without eyeballing the ontology. With the help
of keyword search, the term ps2 can be found easily.
In forming queries, there can be a high chance that the vocabulary used by the user
to describe a query does not exactly match the vocabulary used by a query system
(Preece et al., 1999). This will result in getting insufficient information. Therefore,
