Profile
I specialise in theoretical linguistics, particularly morphology, syntax and their interface. I have been working on formalising the framework in which the paradigm-baed realisational model of morphology is incorporated into Lexical-Functional Grammar (LFG). The linguistic phenomena I am interested in include case and agreement, clitics, verb inflectional morphology, modality and negation. The target languages are diverse, such as Japanese, my native language, Germanic languages (English, Icelandic etc.), Romance languages, in particular European Portuguese, and Hindi/Urdu.

As a long term research target, I am also interested in revealing the nature of the knowledge of language found in human being by using a system with psychological reality. To be more specific, I try to model the correspondences between the capacity of structuring complex concepts and that of constructing linguistic structures by postulating mathematical functions that map different types of linguistic information with each other. Further, this framework allows us to construct a robust model for language evolution, namely the transition from primitive language that has extremely transparent correspondences to conceptual structures to a highly complex symbolic system with grammatical operations.

With regard to teaching, I have a mixed role of a language instructor and a linguist in School of Law. I teach English languages classes and lectures and seminars on linguistics and cognitive sciences, which are provided as a part of minor (sub-major) on linguistics and information science. I also teach lectures on syntax and linguistic typology, both of which are open to the entire university as well as a lecture on linguistic typology at School of International Liberal Studies.

    　View Summary

    This papers aims to present a lexicalist analysis of verb placement variation found in Germanic and Romance languages. Unlike derivational approaches to syntax, Lexical Functional Grammar accounts for different phrase structure positions of finite verbs by base-generating them in functional heads. The present study proposes a framework that allows us to formulate the conditions that license finite verbs to bear a functional category status. Crucial in the analysis is the encoding patterns of person features in lexical entries and their paradigmatic organisation of the lexicon. I will further show that the current proposal can be supported by dialectal variation and diachronic change of verb placement.

    　View Summary

    This research project is an attempt to uncover the structural properties of modal expressions, which can be exemplified by English modal auxiliaries 'may' and 'can'. The analysis formulated within the mathematical linguistic framework of Lexical-Functional Grammar, in which distinct types of linguistic information are encoded in parallel structures. The project successfully account for the common and different characteristics of modal expressions across different languages such as English, other Germanic languages and Japanese.

  • 文構造の階層性に関する研究：形態統語論と言語類型論の視点から

    2010  

    　View Summary

    文構造の階層性に関する研究の中でも，本年度の研究課題ではモダリティの内部構造について，形態論，統語論の観点から言語横断的にデータを観察し，その一部について分析を試みた．文構造，とりわけモダリティ表現が示す階層性に関しては，これまでの先行研究で主に意味論的な考察に基づくものが多く見られるが，形態的・統語的側面を詳細にまとめ，形式的に分析されたものはあまり存在しない．よって，比較的詳細な文法記述が利用できるゲルマン諸語の英語，ドイツ語，ノルウェー語やロマンス諸語のフランス語，イタリア語，スペイン語，および近年モダリティ研究が盛んに行われている日本語に関して，文献や先行研究にあたり，モダリティ表現の形態統語的側面についてまとめた．その上で研究初期の試みとして制約に基づく文法理論の1つである語彙機能文法（Lexical-Functional Grammar）での分析を行った．とりわけ日本語，英語に見られる真性モーダルと擬似モーダルの違いに焦点をあて，詳細に分析したものを論文として発表した．具体的には，句構造のレベルでは両者ともに動詞句を補部に取る助動詞要素として現れる一方，文法関係や素性を表す機能構造においては，前者はMOODの素性を指定する要素であるのに対し，後者はそれ自体が述部（PRED）として機能することを経験的データに基づき主張した．今後この理論的提案のさらなる検証を，これまでにまとめたその他の言語のデータに基づき行い，適宜修正を加えていくこととなる．また，さらに研究の対象を類型論的に多様な言語へと広げ，それらの言語に見られるモダリティ表現の詳細な記述と理論的分析を試みることで，言語類型論，文法理論へのさらなる貢献が期待できる．本研究課題はそれらより広範な研究への第一歩の基礎的研究として位置づけられると考えている．

  • 日本語動詞活用の包括的モデルの構築

    2009  

    　View Summary

    本研究課題は，日本語動詞の包括的な活用モデルを構築することを目的とし，とりわけモダリティ表現の形態・統語的特性の解明，有限状態トランスデューサーによる形態解析に応用可能な形での形式化を具体的な目標として設定した．形態論的な研究としては，Moodの活用素性を[+cond, +conj, +desid, +hort,...]のように設定し，その他の活用素性と並列的に扱う提案を行った．さらに近年Word-and-Paradigmモデルで新たな展開を見せている活用形の推論的関係をアナロジーを基本として記述することを試みた．この形式化は目標として挙げた有限状態トランスデューサーでの形態解析との親和性が高く，今後の研究課題として解析モデルの構築を行う予定である．またアナロジーによる推論的関係は表層的な語形によって定義されるものであり，その点においてJoan Bybeeの提唱する表層的な語形に基づく活用形のモデルを応用して，語形間の関係をネットワークとして関連付けることができることを示した．これらの論点を研究会などを通して他の研究者からの意見も参考にをまとめたものを論文として発表した（業績を参照）．ネットワークモデルは各語形のネットワーク内での関連性の強さを表すことができ，コーパスに基づく統計的なデータを利用することで，より心理的実在性の高いレキシコンのモデルを提供することができる．今後この研究を発展させ，より完成度の高い研究成果を公表するよう試みたい．またモダリティの統語論的な研究として，近年「文構造の階層性」という観点から生成文法，機能文法，Role and Reference Grammarなどの理論的枠組で盛んに進められている．本研究課題ではこれらの先行研究をまとめ，上述の形態論的研究をベースにとりわけ所謂真性モーダルと擬似モーダルの統語的特性の違いについて語彙機能文法の枠組みでの考察を試みた．この研究はまだ現在進行中であるが，その途中段階において，日本語のみならず広範な言語を研究対象に含め類型論的な視点からも議論を展開していく目標を設定し，科学研究費補助金への申請を行った．類型論的にも理論的にも意義のある研究であり，複数年の計画で今後も進めていきたい．
