PT Unknown AU Alicia Fornes Josep Llados Joan Mas Joana Maria Pujadas-Mora Anna Cabre TI A Bimodal Crowdsourcing Platform for Demographic Historical Manuscripts BT Digital Access to Textual Cultural Heritage Conference PY 2014 BP 103 EP 108 DI 10.1145/2595188.2595199 AB In this paper we present a crowdsourcing web-based application for extracting information from demographic handwritten document images. The proposed application integrates two points of view: the semantic information for demographic research, and the ground-truthing for document analysis research. Concretely, the application has the contents view, where the information is recorded into forms, and the labeling view, with the word labels for evaluating document analysis techniques. The crowdsourcing architecture allows to accelerate the information extraction (many users can work simultaneously), validate the information, and easily provide feedback to the users. We finally show how the proposed application can be extended to other kind of demographic historical manuscripts. ER
