What is Text Extraction and Crawling in dox2U?

dox2U’s “Text Extraction'' not only makes searching for documents easy but also intelligent. We use Optical Character Recognition (OCR) & ICR (Intelligent Character Recognition) to analyze your data and convert it into a workable format for you so that it can be easily analyzed, shared, and worked with. 

dox2U is engineered to make working on all types of formats seamless and convenient. For this purpose, dox2U provides the functionality of Crawling and Text Extraction. In simpler words; through crawling you can pull out text from non-image-based, workable formats like .doc, .docx, .txt, etc. On the other hand, dox2U is powerful enough to extract text from image-based, non-editable formats like PDF, JPG, etc., as well! This is achieved through the means of ‘Text Extraction’.

📓Things to be noted 

  • Searchable PDFs are created only in the case of Text Extraction, which can be easily retrieved by running a simple search on your Workspace.
  • The functionality of crawling the text of all workable document formats (.doc, .docx, .txt, .rtf, etc.) is a very useful tool and is available across all Workspaces no matter which subscription plan they are subscribed to.
  • The functionality of text extraction and downloading the text and Searchable Doc for all image-based files (.pdf, .png, .jpeg, .jpg, .tiff, .tif, .gif, .bmp etc) is another useful tool and is only available in Workspaces that are subscribed to Pro plans.

Step 3: Your extracted text as per the selected language will appear on the screen. 

Step 4: In case you want to reparse your document, choose a language from the dropdown menu and hit “Reparse”. Your document will be reparsed according to your newly selected language.
