1st Conference on Biographical Data in a Digital World 2015, BD 2015; Amsterdam; Netherlands; 9 April 2015
This paper presents a solution for mining the biographical information from commentaries on Leo Tolstoy's letters. It is implemented as a part of Tolstoy Digital Project - a semantically marked-up web publication of the 90-volume complete collection of Leo Tolstoy's works. Extraction of relevant biographical information will be used to create an open database for all the persons who were somehow connected with Tolstoy or Tolstoy's works. The paper also accounts for various subtleties of the commentary apparatus and pays special attention to specific difficulties of biographical information extraction, such as the problem of defining the boundaries of expressions denoting profession, or the problem of non-standardized syntactic constructions for kinship relations.
