Part VII
Summary and Outlook
In this part, we will give a summary of the topic and mention several research di-
rections for future study. We try to conclude the topic by answering several impor-
tant questions regarding existing learning-to-rank algorithms, their empirical perfor-
mances, and theoretical properties. We present future directions by giving several
examples.
After reading this part (as well as the entire topic), the readers are expected to
have quite a comprehensive view on the topic of learning to rank for information
retrieval, to be able to use existing algorithms to solve their real ranking problems,
and to be able to invent better learning-to-rank technologies.
