This paper proposes techniques for measuring semantic similarity between documents. We use ontology
to make a machine understand the meaning of a word. Our system measures similarity based on the distance
between a pair of nodes. The words extracted from two documents for comparison are mapped to the nodes. In
this paper, we focused on two processes. The first is a measuring similarity between a pair of nodes in ontology.
The second is a method of aggregating the results of the similarity of each node. Human intuition is influenced
not only by a distance between nodes but also by a structure of the ontology. In the ontology of the domain of
the real world, the depth and width of a node’s descendant are not uniform. Furthermore, a more important word
influences human judgment more strongly. Our approach improved the correlation coefficient between the proposed
approaches and human judgment by considering these human intuitions. |
