I'm not sure how the bet365 poker application works, but the one I play via Facebook (Zynga Poker) is a Java application, and it's going to be challenging to scrape the dealer chat from that.
You'd also like to know how many players there are, and where you are relative to the dealer; that information can be inferred from the dealer chat I have, but the sooner you have that the better. (For example, if you're the first to be asked for a bet, that means the big blind's on your right -- but you still don't know whether there's a full table, or it's heads-up. And that makes a difference to your odds, and therefore to your strategy.)
Once you have access to that information, it would be possible to give you live odds on your hand, and from there make some recommendations on strategy. I'm not sure I'd call that data-mining.
