Matches for analogy between relations related to banana with other conceptsSixth Search:Cook(mother, banana)Cook(chief, pasta)Cook(grandmother, potato)Cook(human, pasta)Eighth Search:Eat(monkey, banana)Eat(rabbit, carrot)Eat(child, chips)Eat(<strong>do</strong>g, meat)Tenth Search:Peel(woman, banana)Peel(knife, carrot)Peel(peeler, potato)Peel(woman, potato)Seventh Search:Cut(man, banana)Cut(knife, meat)Cut(scissors, vegetable)Cut(peeler, potato)Ninth Search:Buy(supermarket, banana)Buy(butchery, meat)Buy(restaurant, pasta)Buy(mother, vegetable)It is worth pointing out that the first concept in each meta-relation presented in Table 5 represents entities(Y) that can perform an action (MR) in something (X). For instance, the meta-relation eat(monkey, banana),formally expressed by MR(Y, X), shows that the entity “monkey” can perform the action “eat” in the object“banana”. With these matches we can define a score which represents the times that the same concept has thesame relation (R) or meta-relation (MR) as banana. Table 7 shows the concepts with higher score based inthe results of Table 2 and Table 5.Table 6.

Forexample, “banana” and “potato” are analogous concepts because both can receive the actions of cook, cut andpeel, different from the first experiment, where “banana” and “car” are analogous concepts because they havethe LocationOf and IsA relation.Of course other meta-relation can be considered to refine the results in order to augment the specificity.The results are just one example to illustrate the potential of the meta-relation, i.e. considering more metarelationthe results will be stronger.5. CONCLUSIONThe early results presented show evidences that the Gentner’s theory to search for analogies in the semanticnetwork of the OMCS-Br Project was not suitable. Because, for analogy, it is necessary to use a network withmore semantic, provided by the addition of the meta-relation created by the combination of Minsky’srelations.It is important to explain that nowadays there are Minsky’s relations and meta-relations in the OMCS-Brsemantic network in order to search literal similarity and analogies. On the other hand, in this paper, we just40
