摘要

This paper describes the results of initial work aimed at increasing the number and improving the quality of textual versions of the historical documents available in Polish digital libraries. Digital libraries community is missing tools that integrate existing digitisation workflow with customizable OCR engine and crowd-based text correction, this paper describes work on providing such a solution. Apart from today's state of the art in this field, this paper includes a description of the Virtual Transcription Laboratory (VTL) prototype, a crowdsourcing platform that utilize the Tesseract OCR engine. The last chapter outlines results of the prototype's evaluation on real life dataset of historical documents from the IMPACT project. Results prove the applicability of the proposed solution as an enhancement of the digitisation workflow.
