我们开始半自动地建立日语“动词+动词”复合词同义表达的数据库。众所周知，日语中有大量由两个动词连接在一起组成的复合动词。然而，我们没有一个全面的日语复合词汇。最近，国立日本语言语言研究所（NINJAL）（2013-15）构建了一个日语复合动词词典。虽然它有意义，例句，句法模式和实际的句子，从他们拥有的语料库，它没有信息的关系与另一个词，如同义词和短语。利用word 2 vec和余弦相似度从Kawahara等人（2006）的“5亿条日语网络文本”语料库中自动提取复合动词的同义表达，并利用k-means ++和主成分分析找到与复合动词意义相对应的合适聚类。从语料库中自动抽取同义词不仅可以帮助人们发现典型的同义词，而且可以帮助人们发现意想不到的同义词和短语。然后，我们通过评估的结果，手工编制日语复合动词同义表达的列表，并将其链接到NINJAL出版的“复合动词词典”。
We started to construct a database of synonymous expressions of Japanese “Verb + Verb” compounds semi-automatically. Japanese is known to be rich in compound verbs consisting of two verbs joined together. However, we did not have a comprehensive Japanese compound lexicon. Recently a Japanese compound verb lexicon was constructed by the National Institute for Japanese Language and Linguistics(NINJAL)(2013-15). Though it has meanings, example sentences, syntactic patterns and actual sentences from the corpus that they possess, it has no information on relationships with another words, such as synonymous words and phrases. We automatically extracted synonymous expressions of compound verbs from corpus which is “five hundred million Japanese texts gathered from the web” produced by Kawahara et.al. (2006) by using word2vec and cosine similarity and find suitable clusters which correspond to meanings of the compound verbs by using k-means++ and PCA. The automatic extraction from corpus helps humans find not only typical synonyms but also unexpected synonymous words and phrases. Then we manually compile the list of synonymous expressions of Japanese compound verbs by assessing the result and also link it to the “Compound Verb Lexicon” published by NINJAL.
