Abstract(in English) In this research, we develop a classification method that assigns fine-grained named entity labels to entries of Wikipedia articles. An essential part of our classification method is the general-purpose orientation so that it can be applied not only Wikipedia articles but also any entity that is not listed in Wikipedia. To achieve that, we propose a method that does not utilize the features that are intrinsically specific to the structure of Wikipedia articles. Specifically, our proposed method uses the distributed representation of both article title and its pseudo hypernym. Experiment result shows that our proposed method yields a slightly better performance compared to the previous research. It also shows that performance can be improved by taking multiple pseudo hypernyms as an additional feature.
