  • Abstract:

    Systematic reviews are literature reviewing processes that aim to retrieve all relevant content based on a specific topic, in an exhaustive manner. Such reviews are particularly useful in healthcare, where decision making must take into account all possible evidence, and are usually done by constructing a boolean query and submitting it to a database, and then screening the retrieved documents for relevant ones. Task 2 of CLEF 2018 eHealth lab focuses on automating this process on two fronts: Sub-Task 1 is about bypassing the construction of the boolean query, retrieving relevant documents and ranking them by relevance based on a protocol that describes a topic, and Sub-Task 2 is about ranking the documents retrieved by an already constructed query by Cochrane experts. We present our approaches for both sub-tasks, which combine a learning-to-rank model trained on multiple reviews with a model incrementally trained on each individual review using relevance feedback.
