An annotation system for enhancing quality of natural language processing

Natural language processing #NLP# programs are confronted with various di#culties in processing HTML and XML documents, and have the potential to produce better results if linguistic information is annotated in the source texts. Wehave therefore developed the Linguistic Annotation Language #or LAL#, which is an XML-compliant tag set for assisting natural language processing programs, and NLP tools such as parsers and machine translation programs which can accept LAL-annotated input. In addition, we have developed a LALannotation editor which allows users to annotate documents graphically without seeing tags. Further, we have conducted an experiment to check the translation quality improvementby using LAL annotation
