Project Description


We are a small research team from Germany and are currently working on a research project, for which we need someone who will assist us in implementing, connecting and modifying 3 open-source projects/libraries.

Our project is focused on social sentiment analysis. Most of the work has already been done.

This are the 3 open-source projects/libraries:

1. Kral: A tool which retrieves information from Twitter, Facebook, Reddit, and Youtube by using their respective API’s

2. Synt: A sentiment classification tool (using NLTK) which has been developed to work with Kral

3. OSAE (Open Sentiment Analysis Engine): It allows humans to flag sentiment for random Twitter samples, which are then used to train Synt.

(Information about the respective projects can be found at the bottom)

All these 3 Projects are from the same developer and should therefore be easy to connect.

For a full understanding please have a look at this info graphic attached!

Kral (1.) and Synt (2.) don’t really need to be modified much and are well documented. You will need to do some modification on OSEA, so that the same set of information (sample tweets) can be classified by several people and that only the tweets which were for example classified as positive 8/10 people are used to train Synt (2.) + the tweet will need to be shown in a random pattern.

We are currently running a Linux VPS and will need you to install all the required repositories, which are listed in the respective open source projects (should be one command in ssh each).

The finished product should allow us to do the following:

1. Define multiple keywords which are going to be analyzed (by Synt) at the same time

2. Have people classify sample tweets by using OSEA

3. Train Synt with the info from 2

4. Have Kral search through Twitter, Facebook, Reddit, and Youtube based on the keywords in 1

5. Analyzing Sentiment with Synt and store this info into a database.

• We want to be able to export this db to excel and distinguish between the different keywords (possibly one db per keyword) – I guess mySQL

• It’s important that we can graph the sentiment vs. time in excel

This should not be very complicated and it shouldn’t take a lot of time.

Most of the work has already been done - have a look at the code and you can judge for yourself (links can be found below). Code is well documented!!!
