text-extraction

I'm looking for a PDF library which will allow me to extract the text from a PDF document. I've looked at PyPDF, and this can extract the text from a PDF document very nicely. The problem with this is that if there are tables in the document, the text in the tables is extracted in-line with the rest of the document text. This can be problematic because it produces sections of text that aren't useful and look garbled (for instance, lots of numbers mashed together). I'm looking for something that's a bit more advanced. I'd like to extract the text from a PDF document, excluding any tables and

I have a large set of real-world text that I need to pull words out of to input into a spell checker. I'd like to extract as many meaningful words as possible without too much noise. I know there's plenty of regex ninjas around here, so hopefully someone can help me out. Currently I'm extracting all alphabetical sequences with '[a-z]+' . This is an okay approximation, but it drags a lot of rubbish out with it. Ideally I would like some regex (doesn't have to be pretty or efficient) that extracts all alphabetical sequences delimited by natural word separators (such as [/-_,.: ] etc.), and

i want to detect text area from image as a preprocessing step for tesseract OCR engine, the engine works well when the input is text only but when the input image contains Nontext content it falls, so i want to detect only text content in image,any idea of how to do that will be helpful,thanks. Take a look at this bounding box technique demonstrated with OpenCV code: Input : Eroded : Result : Well, I'm not well-experienced in image processing, but I hope I could help you with my theoretical approach. In most cases, text is forming parallel, horisontal rows, where the space between rows will

I'm working on a program that downloads HTML pages and then selects some of the information and write it to another file. I want to extract the information which is intbetween the paragraph tags, but i can only get one line of the paragraph. My code is as follows; FileReader fileReader = new FileReader(file); BufferedReader buffRd = new BufferedReader(fileReader); BufferedWriter out = new BufferedWriter(new FileWriter(newFile.txt)); String s; while ((s = br.readLine()) !=null) { if(s.contains("<p>")) { try { out.write(s); } catch (IOException e) { } } } i was trying to add another while loop,

Anyone know of anything they can recommend in order to extract just the plain text from a .doc or .docx ? I've found this - wondered if there were any other suggestions? If you want the pure plain text(my requirement) then all you need is unzip -p some.docx word/document.xml | sed -e 's/<[^>]\{1,\}>//g; s/[^[:print:]]\{1,\}//g' Which I found at command line fu It unzips the docx file and gets the actual document then strips all the xml tags. Obviously all formatting is lost. LibreOffice One option is libreoffice /openoffice in headless mode (make sure all other instances of libreoffice are
