After differentiation of the factors, apropriate information on certain locations needs to be acquired. Since most up-to-date information is transmited mainly as free-text documents via online media, information extraction technology plays a key role in converting such data into valuable and structured knowledge, which faciliates automatic real-estate value estimation. This article reports on creation of a corpus of Polish free-text documents, tagged with name mentions of CIS-relevant entities, which constitutes a core resource for development and evaluation of information extraction components used within a cadastre framework.enText/Conference Paper1617-5468
