Relevance and Importance in PubMed Content Presentation

 

In this talk I will address information retrieval concepts of relevance and importance in the context of PubMed content. As PubMed matures, a substantial portion of its millions of users are from the general Internet population who are not proficient at using the search tags and modifiers. NCBI discovery initiative provides us an opportunity to target this group of users with focused ad portlets that will display content based on their combined relevance and importance. I will show that abstract retrievals can be used as a proxy for importance by comparing them to traditional standard for publication importance such as citation count. A prototype of term-weighted approach for improving the relevance for title search will be demonstrated. I will also present analysis of usage of gene sensor and recent activity portlets, and talk about how the relevance of presented content can be improved by adapting the discovery ads to user’s needs.
