Abstract
To achieve classification of semistructured data with a Kernel method for labeled ordered trees, instances having a labeled ordered tree structure are input and their inner product is computed, the result of which is used for classification learning of the instances. In the inner product computation, a sum of matches is computed for descendant nodes of non-leaf nodes of the labeled ordered trees by applying dynamic programming based on correspondence in which order of the nodes is maintained.
