Abstract
In this paper, we explain the development of a new Mizar tokenizer and parser program as a component of a search system that works on the Mizar Mathematical Library. The existing Mizar tokenizer and parser can handle only an article as a whole written in the Mizar language, however, the newly developed program can deal with a snippet of a Mizar article.In particular, since it is possible to handle a snippet of an article without specifying a vocabulary section of an environment part, it is expected that user input efforts will be greatly reduced.
Highlights
T HE AUTHOR is developing a new information retrieval system that works on the Mizar Mathematical Library (MML) [1]
In order to learn from the drawbacks of MML Query, the newly developing search system extracts features of the input data and compares them with that of theorems and definitions registered in the MML
The Mizar language consists of a context sensitive grammar, and a set of valid symbols are determined according to Mizar articles enumerated in a vocabulary section of an environment part
Summary
T HE AUTHOR is developing a new information retrieval system that works on the Mizar Mathematical Library (MML) [1]. We explain a developed tokenizer and parser program of the Mizar language as a component of our search system
