Questions and suggestions

Hi Dandan
The relationship with the apple, fruit, food is just an example for explaining how the algorithm works. The second paper considers the structure of the ontology while searching. So it ranks and gives results that are similar to the input query and filters out ontologies which have lower resultant vector value. A 3 words input would give you a better precision in the results than a 1 word input. Also these papers were written in 2004 and 2005. So google's api for ontology search must have changed from back then.
