Japanese Word Similarity Dataset

Data

We built a Japanese word similarity dataset including rare words.

We target verb, adjective, noun and adverb.

Data construction

We constructed our dataset following the Stanford Rare Word Similarity Dataset (RW) proposed by Luong et al. (2013).

We extracted pairs of Japanese verbs (including sahen verb) and adjectives (both i-adjective and na-adjective) from Kodaira et al. (2016)'s Evaluation dataset for Japanese lexical simplification.

We employed a crowdsourcing service (Lancers) to recruite 10 annotators to assign 11 levels of similarity for word pairs.

0 (most dissimilar) - 10 (most similar)

Entry

The sample of the dataset is as follows:

word1 word2 mean sub1 sub2 ... sub9 sub10
排除する 無視する 4.6 5 3 ... 5 6
排除する 除外する 6.6 7 6 ... 5 7

mean : average of the similarity scores assigned by annotators

sub* : the similarity score for each annotator

Helper script in src

The src directory contains a helper script to calculate Spearman's rank correlation coefficient used in our LREC paper.

Specifically, we learned word vectors from Japanese Wikipedia to calculatethe rank correlation coefficient between the similarity of word pairs and mean of annotated scores.
