Oh yes, there are some, but these people often do content analyses of
text. Nowadays content analysis of internet stuff is called web content
mining. With search engines one can find appropriate web sites, but many
search engines just process the meta-tags in head of a document, but
leave the rest untouched. What you really must do is to download the
sites you are interested in, you can use an offline-reader for that,
also IE 5.x supports this as far as I know.

I am currently working in this field, I wrote a special offline-reader
named TextGrab that downloads the texts and prepares them for the
analysis of my text analysis program TextQuest. That means, it auto
segments the text into units (the single file), assignes values to
external variables (e.g. file name, date, etc), and writes everything in
one single outpt file. This is required by most ext analysis software,
because ordinary offline-reader just copy the data structure with all
direcotires/folders and their files. For more information look at
