概要

Natural language parsers provide a variety of output formats. The rationale for these output formats vary. Some formats emphasize readability, others provide a format that is easily parsed by other programs. This paper proposes a method of language tree output that enumerates tree node structure similar to Unix paths. This approach emphasizes the software tools methodology of early versions of Unix system and more recently the plan 9 operating system. This method, by providing the structure of the tree in the description of each output node, allows easy interoperates easily with traditional Unix tools, allowing tree queries and other tree operations to be performed by programs like grep and sort interoperate with a wide variety of scriptinq lanquaqes.
