Current Medical Text Indexer (MTI):
The MTI system consists of software for
applying alternative methods of discovering MeSH headings for citation
titles and abstracts and then combining them into an ordered list of
recommended indexing terms. The top portion of the diagram consists of
three paths, or methods, for creating a list of recommended indexing
terms: MetaMap Indexing, Trigrams and PubMed Related Citations. The
first two paths actually compute UMLS Metathesaurus®
concepts which are passed to the Restrict to MeSH process.
The results from each path are weighted and combined using the
Clustering process. The system is highly parameterized not only
by path weights but also by several parameters specific to the
Restrict to MeSH and Clustering processes.

Original Indexing Initiative Prototype System:
The Indexing Initiative Prototype System consists of software for
applying alternative methods of discovering MeSH headings for citation
titles and abstracts and then combining them into an ordered list of
recommended indexing terms. The top portion of the diagram consists of
five paths, or methods, for creating a list of recommended indexing
terms: the INQUERY method, MetaMap Indexing, Barrier Words with
Approximate Matching, Trigrams and PubMed Related Citations. The
middle three paths actually compute UMLS Metathesaurus®
concepts which are passed to the Restrict to MeSH process, and the
outer two paths compute MeSH headings directly. The results from
each path are weighted and combined using the Clustering process.
The system is highly parameterized not only by path weights but also
by several parameters specific to the Restrict to MeSH and Clustering
processes.
