Machine Reading Comprehension (MRC), which requires the machine to answer questions based on the given context, has gained increasingly wide attention with the appearance of deep learning over the past few years. Although the research of MRC based on deep learning is flourishing, there is a lack of a comprehensive survey article to summarize the proposed approaches and the recent trends. As a result, we conduct a thorough overview of recent research efforts on this promising field. To be concrete, we compare MRC tasks in different dimensions and introduce the general architecture. We further provide a taxonomy of state-of-the-art approaches utilized in prevalent models. Finally, we discuss some new trends and conclude by describing some open issues in the field.
