REPORT vin04cIRR/IDIAP Application of Information Retrieval Techniques to Single Writer Documents Vinciarelli, Alessandro EXTERNAL https://publications.idiap.ch/attachments/reports/2004/rr04-12.pdf PUBLIC Idiap-RR-12-2004 2004 IDIAP Accepted for publication by ``Pattern Recognition Letters'', 2005 This work shows Information Retrieval experiments performed over handwritten documents produced by a single writer. The same retrieval task has been performed over both manual (no errors) and automatic (Word Error Rate around 45%) transcriptions of 200 handwritten texts. The results show that the performance loss due to recognition errors is acceptable and that Information Retrieval technologies can be effectively applied to handwritten data.
