Web技術によるデータ公開の方法としてLinked Open Data(LOD)が注目されている.しかし,既存のWeb上の情報資源の多くは人が読む利用形態に適したデータ構造のままであるなど,構造化が不十分であることが指摘されている.本研究においては,異なる性質の要素を持つ複合的な情報資源に対し,相互運用性を持ちかつ情報損失を起さずにLODを適用する方法について検討を行った.この結果,対象となる情報資源に記載されている情報を元にして,文書の構造や使用されている語彙などを分析することにより,LODへの再構成を効率的に行うことが可能であることを明らかにした.また,関連付けが可能な他の情報資源を用いて不足している情報を補うことを前提とした構造化により,人が読む利用形態に適したデータ構造に基づいていても適切なLOD の適用を可能とし利活用しやすくするための一手法を示した.

The 'Neo-Schumpeterian' school is a general term of a researchers group who has been discussing theoretical and empirical development on the Schumpeter's vision of 'Economic Evolution'. This vision is formulated from Marx's vision of dynamic process of Capitalist Economy. Hence, introduction about Neo-Schumpeterian research tendency here gives many hints to modern Marxian economics that goes toward new course of research about an evolution of capitalism and an institutional analysis. We set here three original points at issue refer to Marx's and Schumpeter's 'Economic Evolution', and consider those points while referring to the great work of Hanusch and Pyka, eds. (2007). The first point is on the analytical view of 'Micro-Meso-Macro'. Two main problems are (1)how to place the meso domain and (2)how to examine it concretely. The meso domain plays a roll that connects mutually micro individual decision making/ behavior with macro outcomes, and actualizes 'Economic Evolution' through the process of 'origination → adoption → retention'. The Second point is on recent developments of ways of model building on the process of competition. The evolutionary models of competition process have been investigating since a monumental achievement Nelson and Winter (1982). Now, new various tools-replicator dynamics, evolutionary game theory and agent-based simulation-are introduced and still develop the old models. It is the strong point for Neo-Schumpeterian economics that these tools can cope with diverse aspects of 'Economic Evolution'. The third point is on the 'History-Friendly' approach as a mediator between a theoretical research and an empirical research. When we understand capitalist economy as an evolving economic system, we use enormous historical and institutional research outcomes accumulated by past Marxian economics. Furthermore, this approach will contribute to new theoretical research programs about modern Marxian economics. In the final section, we conclude some meanings of Neo-Schumpeterian contributions for modern Marxian economics and present some problems to be solved.
