question: Is the NLM medical text indexer (MTI) still useful and relevant?
answer: Yes. The NLM Medical Text Indexer (MTI) is still relevant and useful, and needs to be improved and expanded. The BioASQ Challenge results have shown that more machine learning needs to be incorporated into MTI while still retaining the indexing rules that have earned MTI the indexers' trust over the years. MTI also needs to be expanded through the use of full text, when and where it is available, to provide coverage of indexing terms that are typically only found in the full text.
