Title: "A Survey on Interactive Queries"
by
Mr. Qixu CHEN
Abstract:
The field of multi-criteria decision-making has witnessed a growing interest in
interactive queries. Given a dataset, interactive queries first learn the
user's preference by asking the user several rounds of simple questions, and
then the relevant tuples meeting the user's preference are retrieved. This
novel query type can be viewed as combining the strengths of the well-known
top-k and skyline queries. In particular, it eliminates the need for users to
specify a preference function in advance, which is a demanding and sometimes
impractical requirement in top-k queries. Moreover, it provides a controlled
number of tuples as output, addressing the potential issue of overwhelming
results that can occur in skyline queries.
This survey begins by presenting the conventional top-k query and skyline
query. Subsequently, we discuss algorithms for two popular types of interactive
queries: the interactive regret-minimizing query and the interactive best point
retrieval query. We examine the strengths and limitations associated with each
approach. We also introduce several relevant fields which are closely related
to interactive queries. To conclude, we point out the main challenges
encountered in interactive query research, and provide new directions for
future work.
