Probably too complex for this exercise, but no mete/information should be unnecessarily deleted as a rule. ” VPOS=””> show exact positioning of each word on the page and could prove useful in disambiguating layout.I didn’t see a lot of information conveyed in the few files I looked at for this characteristics, but it may apply in other scans or future rescans. may give some clue as to special text like titles or italicized text depending on scanner settings, font sets, etc.”> the HEIGHT attribute of the tag gives valuable semantic clues as to which words on the page are titles and which are simply the body of the text.tags mark paragraph units (this valuable syntactic/semantic information is completely lost when all pages text is concatenated together).tags mark sentence units as far as the ABBYY can detect (parsing for a period cannot always successfully parse a character stream into sentence units, especially with noisy text from newspaper OCR).

Paragraphs)Īlthough it takes more work, the more complex *.xml structure of the smaller sample dataset provides us structural/syntactic information that denotes meaning/semantics: Sample dataset with complex *.xml tag structure that preserves more syntactic and semantic information For example, the more complex *.xml markup in the smaller sample dataset has the tag structure.

The full *.xml dataset makes it easier to pull out each page of OCR text by concatenating within a tag for each scanned page, but this ignores potentially valuable structural information found in the smaller sample dataset *.xml files. …….(all the newspaper text as one long string) The *.xml files in the smaller sample dataset have OCR text set the to value of the attribute “CONTENT” in tags.įull *.xml dataset with simplified *.xml file with all text between tags The full *.xml dataset has each page of OCR text embedded with the text area of tags. These different xml tag structures can be visualized using online xml visualizers. The OCR/scan configuration for generating *.xml files is different for both the full *.xml dataset as well as the smaller sample dataset. A sample dataset with several college newspapers is available on the HackOH5 website and has a wider variety of formats including one with a richer *.xml tag structure. The dataset will be available in a variety of batch file formats (pdf, jp2, html, xml) as well as via online interactive REST-like API requests based upon OCLC’s CONTENTdm digital content server.

You can download it at a *.zip file (514MB) which decompresses into one large *.xml file (1.47GB). The full *.xml dataset was released a few days ago. The other is slightly more difficult to parse but provides a lot more syntactic and semantic information that would be valuable for downstream natural language processing.

One makes it easier to simply grab all the text on the page. Our HackOH5 Hackathon has newspaper OCR scans saved as *.xml files with two different structures.
