find edges for nodes in texts

Hi at all,

I'm very new to this. I don't know if there is a better section for my question. So don't hesitate to move this thread elsewhere.

Problem: I've got a lot of key terms out of some text, which i want to visualize and therefore Gephi came to my mind. So the key terms will be the nodes but I also need the relationships (undirected edges) between them. Is there any tool that can analyse them mainly out of the box and make an importable file for Gephi?
Along with this question I found an interesting paper http://noduslabs.com/research/pathways- ... -analysis/. At the end of section 2 is described how an algorithm works to convert text into graph data (GraphML). But there are no information about how they did it in detail.

Here are some additional information about my data: The text is stored in Excel. Every row contains a cell with a unique text entry of some sentences. If in one cell any of my key terms co-occure they should become linked later in Gephi. All in all there are about 700 terms and more than 2000 texts.

I would be very thankful if you have advices or references for me :)

Thank you for your tip! Over the weekend I've made a little script using python and networkx and loop trough my texts. The generated GraphMl looks good imported in Gephi. So I think the thread can be closed :)
