Some of my recommender and information retrieval systems research has been application-focused. I have led two particular application-driven projects.
Context-Aware Help Search
While interning at Autodesk Research, I prototyped and studied a context-aware help search tool that would monitor the user's interactions with a software program and use the collected data to enhance searches for help resources on the web.

Searching for Research Papers
My first recommender systems research project was a research paper recommender. The key idea of this project was to blend graph ranking algorithms (such as HITS, SALSA, and PageRank) with a collaborative or content-based filter; our goal was to make a recommender that was particularly good at producing reading lists for junior researchers.
We did a small user study indicating some modest improvement from the addition of the graph ranking. While our overall research method was sound and implemented the high-level research pipeline that I recommend, the user study we conducted in this should not be used as the starting point for new studies. Much better user study methods are now available.
