KBLab is publishing a curated dataset of Statens Offentliga Utredningar or SOUs. In order to show a possible use of the dataset, we built some topic models based on it. This blogpost explains the process in more detail.
The datasets can be downloaded from here.
Beside the packages in the requirements, you will also need to install Mallet as explained here. You can also swap Mallet for the python library gensim which is easier to install.
