I have been using LsiModel in gensim for modelling topics from a corpus of 10000 mails. I am able to get the words and word scores for each topic and store them in a file. I have tried using print_topics() and show_topics() but both return only the words & score associated with those words. But I also need the topic score that it outputs to the log file, I want those values in a variable. Like for this example log output below:
2010-11-03 16:08:27,602 : INFO : topic #0(200.990): -0.475*"delete" + -0.383*"deletion" + -0.275*"debate" + -0.223*"comments" + -0.220*"edits" + -0.213*"modify" + -0.208*"appropriate" + -0.194*"subsequent" + -0.155*"wp" + -0.117*"notability"

2010-11-03 16:08:27,701 : INFO : topic #4(116.927): -0.307*"image" + 0.195*"players" + 0.184*"median" + -0.184*"copyright" + -0.181*"age" + -0.167*"fair" + -0.162*"income" + -0.151*"population" + -0.136*"households" + -0.134*"census"
I need these score in a variable.
topic #0 : 200.990
topic #1 : 143.129
topic #2 : 135.665
topic #3 : 125.027
topic #4 : 116.927
Is there any method in the package to get these outputs? Please help.
Yes. These are the singular values associated with each factor.
You can get them from
model.projection.s.
