Test of Accuracy

In order to evaluate its accuracy, we restricted 100 pages, and chose the 5 queries related to AI in English and the 5 queries related to sightseeing in Japanese. Then we ran IICA on the WWW in the following ways.

1.Breadth first search: IICA doesn't use ontologies. It traces hyperlinks on the WWW using breadth first algorithm.

2.Ontology based search: IICA uses ontology-based search algorithm.

3.Ontology based search with heuristics: IICA uses ontology-based search algorithm and heuristics.

We evaluated the result of the experiment according to the standard as follows.

: The collected page is directly related to user's queries.

: The collected page is not directly related to user's queries, but it is related to user's interests.

¡ß: The collected page is neither directly related to the user's queries nor related to user's interests.
