# Enhancing text-based data
Creating or compiling a corpus or converting a raw primary source into machine-readable text formats is a first, necessary step in digitally analyzing texts. There are, however, certain ways in which we can expand significantly our understanding of the semantic links, intertextual parallels and spatio-temporal relations of our text by enriching, enhancing, and annotating them. More specifically we can ehnace our texts by:

- using named entity recognition tools
- using geoparsing tools
- annotating texts
- correcting OCR


## Example: INCEpTION Annotation tool
INCEpTION is a Java-based text annotation platform.
You can [download](https://inception-project.github.io/downloads/) and set up a local installation of the INCEpTION platform or you can [try a demo verion](https://morbo.ukp.informatik.tu-darmstadt.de/demo) online.
`$ java -jar inception-app-standalone-x.xx.x.jar`
