Abstract

<p>This paper explains factors and changes on a traditional information retrieval model，which is illustrated in definitions of “information retrieval”. It also reviews recent trends and evolutions on research and development in the field of information retrieval. Analysis of the full papers titles from ACM SIGIR conferences in this decade shows the rise of new countries, such as China and Singapore, and diversifying research topics including accessing devices, document domains, and the rise of machine learning technologies. Finally, we pick up and discuss the topics and their issues such as learning to rank, neural information retrieval, user studies, query analysis, sessions and tasks, exploratory search, legal document search, entity-oriented search, vertical search, social impact and ethics of information retrieval as emerging topics in the fields.</p>
