We aim at the automatic analysis of semantic structures of natural language texts, and developed a large-scale lexicon of lexical semantics, which represents meanings a word inherently owns. Conventional lexicons cannot assign semantic structures to unknown words (words that do not exist in a lexicon). Therefore, this research proposed a method for representing word-to-semantics mappings as a probabilistic model. We empirically demonstrated that we can obtain a probabilistic model of a large-scale lexicon by using an existing lexicon as training data and statistics extracted from large texts as features.

我们以自然语言文本语义结构的自动分析为目标，开发了一个大规模的词汇语义词典，它代表了一个词固有的意义。传统的词典不能将语义结构分配给未知词（词典中不存在的词）。因此，本研究提出了一种方法来表示词到语义的映射作为一个概率模型。我们的经验表明，我们可以获得一个大规模的词汇的概率模型，通过使用现有的词典作为训练数据和统计数据提取的大型文本作为特征。
