In the past few months, Orange has been getting smarter and sleeker. Since version 3.15.0, Orange remembers which distinct widgets users like to connect, adjusting the sorting on the widget search menu accordingly. Additionally, there is a new look for the Edit Links window coming soon. Orange recently implemented a basic form of opt-in usage tracking, specifically targeting how users add widgets to the canvas.

In the past couple of weeks we have been working hard on introducing a better language support for the Text add-on. Until recently, Orange supported only a limited number of languages, mostly English and some bigger languages, such as Spanish, German, Arabic, Russian… Language support was most evident in the list of stopwords, normalization and POS tagging. Related: Text Workshops in Ljubljana Stopwords come from NLTK library, so we can only offer whatever is available there.

Did you know that Orange has already been to space? Rosario Brunetto (IAS-Orsay, France) has been working on the analysis of infrared images of asteroid Ryugu as a member of the JAXA Hayabusa2 team. The Hayabusa2 asteroid sample-return mission aims to retrieve data and samples from the near-Earth Ryugu asteroid and analyze its composition. Hayabusa2 arrived at Ryugu on June 27 and while the spacecraft will return to Earth with a sample only in late 2020, the mission already started collecting and sending back the data.

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.
