Comparing instances of the ontological concepts

Anton Andrejko and Mária Bieliková

Knowing user's rating of displayed concepts we can acquire some characteristics for personalization purposes by analyzing the content. In this paper we present a method for comparison of instances of ontological concepts. During the comparison we examine the relationship of the compared concepts based on the used class taxonomy. We also traverse all of their attributes, which might be either data type or object type attributes. For each attribute we look for adequate attribute in the second instance to be compared. When comparing attributes, a simple comparison of strings does not give satisfactory results as the semantic dissimilarities need to be evaluated. We extend achieved similarity measure with content's attribute that caused different rating according to defined threshold values.
