Before it gets too far behind us, I wanted to write briefly about the Health 2.0 Conference, which was held in San Francisco on October 22 and 23rd. The Health 2.0 Conference focuses on the application of Web 2.0 technologies to the fields of medicine and healthcare. Specifically, I wanted to comment on health search, the semantic web and the demonstration of the health 2.0 service iMedix.
Search engines today rely extensively on keywords. However, with health-related searches, context or meaning takes on great importance. Consider this: a study earlier this summer found that simply replacing the search term “vaccine safety” with “vaccine danger” replaced virtually all accurate search results (out of the first 20) with inaccurate results . Granted, there are several limitations to the study (small sample size, controversial topic), but it nonetheless illustrates how a single keyword can dramatically alter search results.
Frequently, health search results are incomplete, inaccurate or altogether wrong. Indeed, although there is a large amount of reliable health information online, an equal or greater amount of misinformation also exists. Many health seekers have grown accustomed to repeatedly reviewing search results, revising the search criteria and searching again until they find the right keywords that return the desired information. Ultimately, health seekers are faced with determining which sources of information are reliable. One way to confront this issue is to discard the traditional search engine approach based on keywords and use Semantic Web technology.
Using medical semantic technology to translate health questions into a series of weighted medical terms, iMedix returns relevant search results from top-rated sources. iMedix CEO and cofounder Amir Leitersdorf presented a demo of the health 2.0 service at the Health 2.0 Conference. The fast-paced iMedix demo (presenters were only alloted 4 minutes for each presentation) provides a nice overview of what happens “behind the scenes” when a question is posted to the iMedix community.
