"Finding Document Similarity Based Mostly on Keywords and Title"

Hi all,
Sorry for the long title, but I could not find an efficient one Smiley
I am new to RM, and I am finding document similarities via RM. My sources are the webpages, and I basically read them and compare them.
So far so good; but here is the problem:
I want to determine keywords and title for the documents, and I also want to assign weights to keywords. When I run the program, title and keywords seem to be '?'. So, is there a way to manually enter the keywords and title for now? For later stages: how can RM automatically get keywords from webpages?

Hi,

if you just want to assign a score, based on the keywords you might want to have a look at this thread http://rapid-i.com/rapidforum/index.php/topic,8638.0.html

If you want to find the words automatically, you can do standard text mining on them. The trick is, that you can cluster the documents. Afterwards you can use the cluster information as Label and do a feature selection on them. Thus you can get the important words per cluster.

Cheers,

Martin
