They include preambles and footnotes, are formatted visually, and in general do not follow csv-guidelines. The ability to easily ingest such files into data systems opens up many opportunities for data analysis and processing. With ExtracTable, we present a system that can automatically ingest a large variety of raw data files, including text files and poorly structured csv-files by detecting row patterns and thus separating their values into coherent columns. We manually annotated 957 files of a wide variety containing 1208 tables. We show experimentally that ExtracTable can correctly parse 90% of all lines in structured files and 76% of all lines in files with a visual layout only, significantly outperforming state-of-the-art.","PeriodicalId":421643,"journal":{"name":"Datenbanksysteme für Business, Technologie und Web","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129806476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
