An Exploration of New Ranking Strategies for Medical Record Tracks
نویسندگان
چکیده
We report our system and experiments at the 2011 Medical Record Track. Our goal is to return most relevant visits according to a query. In particular, we start with an axiomatic retrieval, and combine it with an aspect based term proximity strategy to improve the retrieval performance. We also propose a “disease-diversity” strategy based on the assumption that most of documents only contain information related to one main disease. Query expansion using external resources has also been studied.

متن کاملAcceleration-Based Quality Assessment of Railway Tracks using a 2D simulation model and recorded track data
Car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. Though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. To do so, car body acceleration is determined using a 10 DOF simulat...
