To make it easier for you to navigate through the file system and create folders, here are some basic commands of the Bash Command Line: The data of all past conferences is provided by the International Labour Organization (ILO) and is publicly available. Throughout this lesson you will work with historical documents from the First International Conference of Labour Statisticians from 1923. If that doesn't work, go to Systems Preferences, click on Security & Privacy, and then click Open Anyway. If you are using a Mac and receive an error message that the file is from an “unidentified developer,” you can overwrite it by holding control while double-clicking it.

Analyze a large corpus using Topic Modelling to get a quick overview of the topics it contains.

Do all of the above at once (batch processing) with a large corpus.Combine images and PDFs into a single PDF file.Recognize and extract texts in PDFs with Optical Character Recognition (OCR).In more technical terms, in this lesson you will learn to: You don’t have access to commercial software, such as Adobe Acrobat Professional or Abbyy FineReader.You want to examine your corpus by the means of Distant Reading and therefore need it to be in plain text format.You work with a large corpus and you do not want to touch each file individually (batch processing).Your files are in PDF file format or can be converted to this file format.You work with text-based sources and need to extract the content of the sources.If you meet one or more of the following criteria, this lesson will be instructive for you: However, PDF documents are only suitable for digital processing to a limited extent and must first be converted into plain text files. As a result, humanities scholars are increasingly exploring larger collections by means of Distant Reading and other algorithmic tools. Even more dramatic is the increase in the amount of data in digitally created sources such as those necessary for corporate and government reporting. Archives have begun to digitise entire collections and make them accessible via the Internet. The digitisation of these objects increases their accessibility and availability. This includes digital reproductions of physical sources such as books and photographs as well as digitally created documents.

You may want to see my early notes when I first learned to install IM manually. The second line seems to be needed on macs so that you can display images, but you need to install X11 (which may come on your install CD, perhaps as part of Xcode Tools, but is probably not installed by default. That way I do not have to supply the path to the script.Įxport PATH='$:/Users/fred/Applications/ImageMagick-Scripts/bin' It is modified to include the path to where I keep my scripts. profile file (a hidden file in my home directory, but you can use BBEdit to view and edit hidden files if you need some text editor for that). My procedure now is to keep all my images at the root of my home directory (to avoid the path to the images), but store my scripts at Applications/bin/ImageMagick-Scripts. I learned quite a lot from Anthony Thyssen in the beginning. I am on a mac (OSX Tiger) and have built many scripts (see ). Pathtoscript/scriptname arguments pathtoinputimage pathtooutputimage
