Construction of a Simple Inference System of Textural Similarity (oka1 RITE2).
Hirotaka Morita, Koichi Takeuchi · 2013
The motivation to join the RITE-2 task is to understand what kinds of linguistic and common knowledge are needed to recognize textual similarity in RITE-2 data. After a shal-low manual analysis of RITE-2-bc example data, we found that morpheme similarity would be a major factor to rec-ognize textual similarity. Thus we construct a threshold based inference system with Japanese WordNet as a base system that can be extended to more deep linguistic knowl-edge in further development. The preliminary experimental results show that the simple noun similarity based system outperformed the WordNet based system; but in the formal run, the WordNet based system gives the highest score in f-measure among the other simple system we constructed.
