Math Retrieval Subtask

This paper describes and summarizes experiences of Masaryk University team MIRMU with the mathematical search per-formed for the NTCIR pilot Math Task. Our approach is the similarity search based on enhanced full text search uti-lizing attested state-of-the-art techniques and implementa-tions. The variability of used Math Indexer and Searcher (MIaS) system in terms of the math query notation was tested by submitting multiple runs with four query nota-tions provided. The analysis of the evaluation results shows that the system performs best using TEX queries that are translated to combined Presentation-Content MathML
