As others have said a lot of girls are into saying "Love you" and even hugging you but it will more than often mean nothing more than friendlyness.

You need to see if there are more signs.

Does she go out of her daily work to come and talk to you ?
Does she ask you alot of quesitons and always seems interested in what you are doing ?
Does she sit extremely close to you ?
Have you caught her starring at you ?
Does she act like this with everyone or pay more attention to you ?
Is she interested in your bobbies, or ask what you are doing at the weekend.
Has she asked for your email / mobile / MSN address ?

These are all things that can show she could be interested. But you need a few things from that list to really make a good judgement on whether she is interested.
