Hello world and welcome to the 10th annual CS 50 Fair.

My name is David Malin and this is indeed the 10 CS 50 fair.

Back in the very first day of 50 Fair, it was pretty much with me holding a balloon, hoping that people would come by was one.

But now we have hundreds of CS 50 students, hundreds of students and faculty and staff across campus and even hundreds of CS.

With AP students who were taking CS 50 at their own.

We just got started about 1/2 an hour ago is our second annual live show of the CS 50 pairs.

This is also a lot of fun and exciting indeed.

Doug is looking forward to going strong for the next several hours.

So many hours, so many hours of CS 50 fair.

And what are we gonna see throughout the day?

We're gonna do interviews from the floor from the interview station.

There's a whole lot of things that are gonna happen today.

We'll see lots of changes as Well, we've changed the way the look of affairs you mentioned things changed quite a bit in the last 10 years or more balloons this year.

Instead, above our heads, we have hundreds, maybe thousands, of L E D lights, all of which are software controlled.

So that Colton and the team on lighting can actually synchronize the lights with the song that is playing always, always innovating Here is 50.

Shall we take a look at the way should get right to the action.

So I'm gonna talk things over to the interview station where are not have a student who's gonna be talking about a stock analyzing.

I'm are not a teaching fellow for the scores.

And today I have with me, my two lovely friends Paul and Andrew here to talk more about that project.

I'm a junior economic concentrated statistics concentrator in the house.

You know what made you guys stop with the project.

So our project is stock sentiment analyzer.

So what we do is we allow the user to choose a portfolio of stocks to analyze it in our program allows the user to gather data on the sentiment as well as a stock price and see trends between them.

And if we go on sentiment record, So my portfolio Curly consists of Apple, Tesla and Alibaba.

Then we can analyse apple, and what I do is show us a graph off the sentiment score.

So a ground of sentiment and the stock price so yellow is the sentiment on a scale from minus 1211 Being positive and red is a stock price.

Yeah, and they're really easy to compare in this because the grafts have dual axes that make it really see also shows remarkable trends that overtime really poorly.

Things correlate pretty well now, and more data collects sensitivity for the markets close so that you also have the last couple days tracked.

You could do this for any stock once we put it in our database.

So it updates every 90 seconds every 90 seconds gathers data.

And one of the cool things is that in our database, if you select the stock that's not yet in our database will automatically at the database and start from that date on gather data on the sentiment and stock price.

And then the stock prices over time s o for the sentiment way.

So we gather tweets from an A P I called stock to it, gathers the 30 latest relevant tweets on a stock and then use natural language processor to analyze the sentiment.

Each street and the average sentiment score is seven score of stock in that time.

I mean, the name is quite literally our initials.

Paul obviously comes first, but then way have 1/3 partner who happens to be abs like missing at this moment off enjoying the fair eso just hearin it shows.

Thank you so much, guys, for talking to us more about your project.

All right, so that was a really cool project.

And, uh, you kind of remind me a little bit of he said, six.

He's had seven from this year for anybody who followed along.

But before we get too far away, there's somebody sitting next to me.

The fair look so much different than last year, but I'm loving it already.

Got to see a few projects, and it's pretty great.

Erin's gonna be with us on and off for the next couple hours.

Aaron, it's fairly nice with, Well, thank you very much.

I didn't have another one plan, but I got more to come because you'll have.

I think we're about to go back out into the field in just a moment.

But any other thoughts on the subject change in scenery this year before we head over.

I mean, I think that the students are definitely enjoying this new vibe.

I think it's ah, really interesting atmosphere to be here.

Live and help you guys get to get a little taste of that today.

All right, so you kind of take a look at that stock analyzer project was really cool.

Kind of tied together a couple of pieces of new things.

Always fun to see students sort of taking things you learn in the class and turning it up a notch and really innovating and doing something.

So I believe now we're gonna head out into the field and take a look at another student project right in.

All right, So we're here with Hillary and Anna, and they're gonna share their project with us.

What does it do and give us a little bit of an elevator pitch tweets, and basically, you can search any trending topic.
