The NLM Indexing Initiative's Medical Text Indexer

The Medical Text Indexer (MTI) is a program for producing MeSHindexing recommendations. It is the major product of NLM's Indexing Initiative and has been used in both semi-automated and fully automated indexing environments at the Library since mid 2002. We report here on an experiment conducted with MEDLINEindexers to evaluate MTI's performance and to generate ideas for its improvement as a tool for user-assisted indexing. We also discuss some ltering techniques developed to improve MTI's accuracy for use primarily in automatically producing the indexing for several abstracts collections
