So now, you've warmed up with some basic questions that we can answer

about social networks and it's time for you to ask your own questions.

So in the course of this week, you'll be identifying questions that you want to

answer about data that you care about.

So you get to pick the social network, find the data that underpins that social

network and then think about what you'd like to discover about that data.

Now, that's really open ended and it might seem a little bit daunting.

How do I know what to look for?

But what we'll do this week is give you a few examples.

So you've already heard a little bit about community finding,

which is what I introduced to you last week when I gave you the overview of

the scope of a project that you might care about.

And so what I'll do this week is give you some more details with the algorithm that

goes at the heart of community finding and then Christine, and

Leah will give you three other examples of algorithms that can answer really

interesting questions about graphs, and social networks.

And again, give you some pointers to references for those algorithms, but

also some ideas about how to implement them using the tools that you know

from the courses in the specialization so far.

So by the end of this week, you'll have three very solid leads and

classes of questions that you might answer about your data.

But the thing is that the work's not over there,

because maybe you want to ask a tweak of one of those questions or

maybe you have something else completely in mind and that's great.

This capstone is really about your interests and your creativity.

And so, we really encourage you to keep looking and research.

Google is your friend here.

There's lots of information online.

Lots of papers that have been written about graph algorithms and in particular,

the application to social networks.

And also, the books that we've pointed to might give you some ideas about where you

might want to look further.

So really at this point, we just want you to get excited about and

start giving some direction to the project that you'll be developing, so

that then you can keep on working on it in the following weeks.
