[infomap-nlp-users] Hor get all coordinate vectors?

[Sverker L. <sv...@de...>]

Dear "infomap-nlp-users" mailing list,

I have some questions:

1. How do I know which documents have which ID?

2. I need the coordinate vectors for *all* documents and *all* words. Is  
there a simple way to get these data?

3. Which is the best way to exclude words with low frequency from the  
model (before the diagonalization)?

I'm trying to use infomap to visualize relations between documents, in the  
style of Multiple Correspondence Analysis.

Yours sincerely,

Sverker Lundin

Hi Sverker,

Sorry not to reply for a while, I'm horribly busy. (again. long story)

I believe there's a print_doc function that will take a document ID and 
return the document.

I believe Scott implemented something that did this over the summer. I 
don't think it's in the released version, but should be under CVS on 
Sourceforge. Scott may be able to help more.

I think you set the ROWS variable in /admin/default-params

Very cool. Let us know if you get interesting results.

Again, apologies for not giving more detailed answers. I hope this 
helps somewhat.
Best wishes,
