Derric,

The SVD is used _very_ widely indeed!  Also look for where "PCA" has been 
used.

I have written an introduction to it for undergrad math students, and it 
includes a lot of references for more detail, examples, theorems, etc:

 	http://people.maths.ox.ac.uk/porterm/papers/s4.pdf


The voting matrix in one of the examples in the paper can be construed as 
a signed two-mode network (person i votes either yay or nay on a bill), 
though those of us who did the calculation didn't bother thinking of it as 
a network for the purpose of that calculation.

One can also build a lot on SVD-like things (see, e.g., the work by Poole, 
Rosenthal in others in political science over the past many decades).

I'll leave it to someone else to comment on the use of SVD in bipartite 
networks per se (with a networks perspective, which the above paper does 
not take explicitly), as I am pretty sure that somebody has brought that 
up on this list-serv before.

I hope this helps.

> Hello All,
>
> I am wondering if someone can help me out with an issue I have in my
> research. I have data on information sources from a name interpreter
> question. This question asked if they had heard of, read, think the
> source is reputable and if they agree with the source of information
> on a certain issue (valued data). It also includes sources that are
> supportive of the issue and sources that disagree with the issue at
> hand (+/- data). I want to show that sources of information are
> correlated to beliefs and concerns on the issue and that groups may
> form around these based on where people get their information.
>
> I ran across the use of SVD in a couple manuscripts and it seems very
> promising but my searches are not showing wide utilization. It seems
> that the mathematics camp is more supportive of the technique? I am
> wondering if you all can help point me to more literature or maybe
> even give me some advice on if I should abandon this and focus
> elsewhere or should I pursue it with gusto? Part of my issue is my
> time-line for my dissertation so I could also abandon this for more
> familiar techniques and then try SVD with my data in an attempt for a
> paper later?
>
> Any replies will be greatly appreciated!!

> Thank you,
