Improving Toponym Extraction and Disambiguation Using Feedback Loop

This paper addresses two problems with toponym extraction and disambiguation. First, almost no existing works examine the extraction and disambiguation interdependency. Second, existing disambiguation techniques mostly take as input extracted toponyms without considering the uncertainty and imperfection of the extraction process.it is the aim of this paper to investigate both avenues and to show that explicit handling of the uncertainty of annotation has much potential for making both extraction and disambiguation more robust.keywordshide markov modelconditional random fieldproperty descriptionextraction modelentity extractionthese keywords were added by machine and not by the authors.
