Reproducing a legally accessible protected work for text and data mining is a permitted exception under CDADC Article 75.º(2)(w), unless the rights holder has expressly reserved that use through a machine-readable means, such as optical reading of content made available to the public online, or another adequate means.
A separate, unconditional exception in Article 75.º(2)(v) covers a research organization or a cultural-heritage institution carrying out text and data mining on legally accessible works for scientific research. Article 75.º(3) defines text and data mining as any automated analytical technique aimed at analyzing text and data in digital form to produce information such as patterns, trends, and correlations.
