used algorithm proposed by M.F. Porter in 1980 was
used in our approach [30]. The prototype uses a PHP
encoding of the Porter Stemmer algorithm,
implemented by Richard Heyes in 2005 [31] and
extended by us with a look-up algorithm. This look-up
algorithm checks the stemmed words in a given table
to ensure that the word is correctly stemmed. The lookup
table used in this approach is the WordNet lexical
database developed by Princeton University [9]. This
combination ensures a more precise approach and
extends the word stemming. The following figure
shows the process of idea generation and the
algorithms implemented in the AI.
