Mathematical Search Engine
Mišutka, Jozef ; Galamboš, Leo (advisor) ; Dvorský, Jiří (referee) ; Kohlhase, Michael (referee)
Mathematics has been used to describe phenomena and problems in many re- search fields for centuries. The basic elements used in the description are formu- lae which express information symbolically. However, searching for mathematical knowledge in digital form using available tools is still cumbersome. We address this issue by presenting the mathematical search engine EgoMath, based on a full text searching, which can search for mathematical formulae and text. We perform an eval- uation over a large collection of documents showing that our solution is usable. Our approach can be used with huge document collections by applying one specialised technique. In order to provide a valuable evaluation of the quality, we built an al- ternative mathematical search engine using the feature extraction technique proposed by Ma et al. We propose important improvements to this solution achieving interest- ing results. We perform the first ever cross-evaluation of mathematical search engines based on different algorithms. A comprehensive survey of existing techniques avail- able, presented in this thesis, completes the picture of mathematical searching.

Title: Mathematical search engine Author: Jozef Mišutka Department: Department of Software Engineering Supervisor: RNDr. Leo Galamboš, Ph.D. Supervisor's e-mail address: leo.galambos@mff.cuni.cz Abstract: The WWW is dominated by search engines such as Google. They are inseparable part of everyday search for information. Theoretical research field interested in searching, the information retrieval, focuses mainly on the natural language constructs - words. During the last years the field has been extended to other searchable content as well. The world of mathematical knowledge on the WWW has grown enormously. The importance of a general mathematical search engine is clear. However, this research field had been abandoned until very recently. Despite the fact that an active ongoing research is in progress, few practical results have been presented. The main goal of this thesis is to fill this gap. A new mathematical search engine was proposed with the focus on applicability. As the only capable search engine of indexing WWW effectively is the full text search engine it was used as the basis. The mathematical extension was designed as an extension which allows it to exploit and use all the advantages of the full text search engine. Most of the mathematical documents do not contain semantic information. The...
