Adding a Text File or a PDF Document

As language and information grow increasingly complex, text network visualization can be extremely useful for a better and clearer understanding of long texts, complex writing samples or even just getting a different perspective on your writing and research. 

The InfraNodus graph will provide you with the main topics of the text you want to analyse, how these topics are related to each other and the structural gaps in the discourse to give you some hints to develop it further. 

Visualise a New Text or a Document

1.   First, you need to open the top left menu and click +add new graph, give a name to your new text and click the save button (as seen on the picture below with the red circle):
 

2.   Click +add new graph, give a name to your new text: 

Alternatively, you can go directly to InfraNodus Apps and then click the Advanced Import app button.

3.   Then click the + File button at the edit pane at the bottom left. If you don’t see the edit pane, click the show statements button at the top right corner:

You will find yourself on the Import File page. Click Choose file to select the file you want to visualize from your disk, check that it’s a txt or a pdf file, check the name of the new graph, and click Save:

4.   After a few seconds you will see a new page. If your file was big, you might have to reload it after a few seconds to see the full graph. To do that, click Ctrl+R (Cmd + R on Mac) or click the button. You will see the full graph:

The bigger the node, the more important that word is in your text. Words that often appear together are grouped in the same colour and placed close to each other on the graph.

5.   To get a cleaner view, you can: 1. Hide the text panel by clicking the Graph menu at the top left 2. Minimise the edit panel by clicking the minimise icon

You can also clean up the graph by removing irrelevant words. For example, in a scientific paper you may want to remove words likefig, rev, and doi or an author's name since they appear a lot but don't add meaning. To do this, simply click on a node and add it to the stopwords list. It will disappear from the graph.
 

6.   Once your graph is clean, click the Essence tab at the top to see a summary of the most important keywords and topics in your document. The Essence tab in InfraNodus gives you a concise interpretation of your text by extracting its most central themes and concepts from the underlying network. It helps to understand what the discourse is fundamentally about by summarising the dominant ideas, key connections, and overall structure of meaning.
