The task is to find out the name, email and phone of as many documents
as possible. Since the documents are not in a specific format, you
have to do a lot of guessing and getting approximate results is fine.
For example, to find the email you can use a simple regexp. If there
is a match you can be certain that that is the authors email. But what
algorithms can you use to figure out the other information?
Tricky! :-)
How would _you_ recognise them? Have a look at the documents and see if
you can see a pattern. For example, names and address often consist of a
sequence of words in title case, eg "Björn Lindqvist", which might help
you narrow down the list of possibilities. What do telephone numbers
look like, etc?
