Automated Indexing: Weighted Tags for Better Search
Article-level SMART Content tags help
confirm relevance and provide a topical
overview about a piece of content.
Paragraph-level SMART Content tags
uncover highly-relevant information not
necessarily evident from the title or
abstract alone.

Clinical Search Results
Search
BNP guided therapy for CHF
TM
• 1 relevant result, last updated
in 2009
• 310,000 results—mostly news
summaries
• Requires Google Scholar to
produce a sublist of journal
articles
• 10 results in reverse
chronological order, burying
several key papers
• 2nd result is an unwanted
editorial comment
• Result set misses several key
publications due to lack of term
expansion and acronym
confusion
*Based on an actual case study. Search conducted in March 2011.
