Do computer-generated summaries, "The Bottom Line (TBL)" accurately reflect published journal abstracts?

txt2MEDLINE allows users to search and retrieve MEDLINE/PubMed citations using SMS text messages. "The Bottom Line" (TBL) concept was developed because of the 160-character limitation of text messages. TBL algorithm generates a shortened version of the published abstract thereby decreasing the number of characters while attempting to maintain the key points of the full-length, author-generated abstract. The data seems to indicate that the TBL generally conveys the essential elements of the full abstract.
