Capabilities and limitation of topic modeling were explored through a literature review. A design opportunity was recognized in literature review for students as novice researchers. Interviews were held with master students to gain insight in their literature review process. Students reported issues with the process of related document acquisition and relevant information extraction. Document exploration was chosen as the most promising activity concerning both processes. PaperScout, a prototype for a tool which improves document exploration, has been proposed and tested with students. Recommendations have been made to further the development of PaperScout and to make other contributions to the larger process.
