We present and analyze the results of the MATHWEBSEARCH (MWS) system in the Math-2 task in the NTCIR-11 Information Retrieval challenge. MWS is a content-based full-text search engine that focuses on low-latency query answering for interactive applications. It combines a powerful exact formula unification/matching with the fulltext search capabilities of ElasticSearch to achieve simultaneous full-text search for mathematical/technical documents. MWS 1.0 focuses on scalability (memory footprint, index persistence), integration of keyword- and formula search, and hit presentation issues. It forms a stable basis for future research into extended query languages and user-interaction issues. The system has been integrated into high-profile information systems like Zentralblatt Math. In this paper we describe MWS 1.0, evaluate the submission and results for the NTCIR-11 Math-2 Task and conclude with future work suggested by the task results.
