Doctor Kurohashi's laboratory at Kyoto University proposed a method for classifying
Japanese documents without performing any morphological
parsing of these documents but just by observing the
kanjis
.
The model was trained using a database of texts already classified
according to their topic (philosophy, architecture etc...) to
extract the kanjis characteristic for each topic using a
method. The kanjis found to be characteristic can
thereafter be used to classify new texts depending on the kanjis
observed in it.
