1The tutorial is divided into the theoretical and empirical parts. In the theoretical part, the characteristics of parliamentary debates and the ParlaMint corpora are presented in Chapter 3 and the topic modelling method in Chapter 4. The empirical part begins with Chapter 5, guiding the reader through analysis preparation and explaining how to set up the Orange software, import and check the data, and prepare a data sample for the analysis. Chapter 6 moves on to the central empirical part of the tutorial, composed of three related tasks. The tasks use topic modelling and various visualisations to explore the topics of the debates and the prominence of different topics in general and during the COVID-19 pandemic.
2All the resources and tools used in this tutorial are freely accessible online. You can find the detailed instructions on downloading the ParlaMint data and setting up the Orange software in Chapter 5. If you are mainly interested in analysing texts in Orange, you can begin with Chapter 5. However, we recommend reading the introductory theoretical chapters containing key information on understanding the data and the topic modelling method. Reading the entire tutorial will reduce the possibility of non-critical use of the method and inappropriate interpretation of the results.
3Alongside the descriptions of the procedures, the materials include numerous screenshots that show widget1 settings and results. At the beginning and end of each task, you will find the workflow with the sequence of widgets used. The complete workflow is available for download in Chapter 5.1. However, we recommend that you create your own workflow by following the instructions in the tutorial in order to better understand the individual steps of the analysis. The widget names are typeset in bold, while widget settings, variable names, search queries anddiscussed words are italicized.
4Certain steps of the tutorial might be quite laborious for some computers which results in the process in Orange being stuck or aborted. In this case, you can opt for Option 2 instructions which will be provided in the relevant parts of the tutorial.
1The orange Try-it-yourself frames include instructions for independent research and help you consolidate the acquired knowledge.
