FS-LF システムマニュアル バーション 1.2
Abstract:This manual presents user documentation for the ATR Interpreting Telephony Research
Laboratories FS-LF, the Feature Structure to Logical Form Translator. This package
translates information represented in feature structure format into a logical form
representation. Feature structures are translated directly, in a one-to-one format.
The FS-LF translator was developed to allow natural-language understanding
programs that work with logical forms to be able to take input from the results of programs
that work with feature structures.
The FS-LF translator version 1.2 is a special-purpose system that only works
with Nadine-style feature structures, as defined by the Hasegawa RWS rewriting system.
This system only translates information that is actually present, from one
representation scheme to another; different efforts are required to add
information that is not explicitly present in the feature structure (by doing
anaphora resolution, etc.). The translation is performed using automatically constructed
functions. The FS-LF system is thus similar to a compiler-compiler. This allows the
translation to be extremely rapid, which permits use of the package in a run-time
system.
