| Outline of Final Research Achievements |
A mathematical formula is an important component of scientific documents with a specific semantic structure. In this research, we aim at developing a framework for semantic enrichment of mathematical formulae using natural language processing techniques. We conducted researches on following techniques for mathematical information access and showed the usefulness of the proposed methods: automatic extraction of natural language description of mathematical symbols and formulae, extraction of dependencies between mathematical formulae in a document, and a fast algorithm for similarity search of a large-scale, complicated tree-structures. We also organized a shared task for mathematical formula search and constructed several evaluation datasets which can be shared by researchers in the related field.
