Publication number: 20150248382Abstract: An apparatus and method for converting an electronic form. After a table is extracted as an image of information on a cell range instead of text by analyzing the table of the PDF document file requested according to a standard operation of the PDF document file requested to be converted and converting the analyzed table into the standard document based on the prescribed reference information, the standard document including information on cell range corresponding to the table of the converted PDF document is converted into the XML document according to the XML conversion format. In turn, as the XML document is structurized and provided according to the prescribed XML reference information and the XML document file, the PDF document file is accurately converted into the XML document file which is in turn provided, thereby improving the form conversion quality of the document, and also easily storing and managing the document.Type: ApplicationFiled: November 12, 2013Publication date: September 3, 2015Applicant: KOREA INSTITUTE OF SCIENCE 7 TECHNOLOGY INFORMATIONInventors: Yong Ju Shin, Kiseok Choi, Jaesoo Kim, Hongro Lee, Kyu Chul Lee, Seung Jun Cha, Gyu Jin Chol
