Title:   Automated Quality Assessment of Obesity Websites 


Abstract:
   We previously developed an automated quality rating technique
   (AQA) for depression websites and showed that it correlated
   0.85 with expert ratings using evidence-based guidelines.
   AQA scores the pages within a site against complex learned
   'quality' and 'relevance' queries using the BM25 ranking
   function. It then aggregates these scores across sites using
   a learned combining function.

   In this talk, we report on our generalisation of the AQA
   method and our evaluation of its application to a different
   health domain, namely obesity. We find that correlations as
   high as 0.80 averaged across ten folds can be obtained, but
   that performance is quite dependent on the choice of the high
   quality websites used for generating the 'quality' query.
   This is ongoing work.
