Text Workshops in Ljubljana
In the past month, we had two workshops that focused on text mining. The first one, Faksi v praksi, was organized by the University of Ljubljana Career Centers, where high school students learned about what we do at the Faculty of Computer and Information Science. We taught them what text mining is and how to group a collection of documents in Orange. The second one took on a more serious note, as the public sector employees joined us for the third set of workshops from the Ministry of Public Affairs.

Text Preprocessing
In data mining, preprocessing is key. And in text mining, it is the key and the door. In other words, it’s the most vital step in the analysis. Related: Text Mining add-on So what does preprocessing do? Let’s have a look at an example. Place Corpus widget from Text add-on on the canvas. Open it and load Grimm-tales-selected. As always, first have a quick glance of the data in Corpus Viewer.

Data Mining for Political Scientists
Being a political scientist, I did not even hear about data mining before I’ve joined Biolab. And naturally, as with all good things, data mining started to grow on me. Give me some data, connect a bunch of widgets and see the magic happen! But hold on! There are still many social scientists out there who haven’t yet heard about the wonderful world of data mining, text mining and machine learning.

Rehaul of Text Mining Add-On
Google Summer of Code is progressing nicely and some major improvements are already live! Our students have been working hard and today we’re thanking Alexey for his work on Text Mining add-on. Two major tasks before the midterms were to introduce Twitter widget and rehaul Preprocess Text. Twitter widget was designed to be a part of our summer school program and it worked beautifully. We’ve introduced youngsters to the world of data mining through social networks and one of the most exciting things was to see whether we can predict the author from the tweet content.
