International Semantic Web Summer School in Bertinoro

Image
This summer I had a very nice opportunity to attend to the  International Semantic Web Summer School (ISWS) . The school took 1 week and was mainly organized for Phd students, young professionals and graduates who are interested in topics like Semantic Web and surrounding technologies (e.g Natural Language Processing, Machine Learning, Ontology Design, Blockchain). My master thesis topic was ' Usage of Linked Open Data in Content-Based Recommender Systems for Real World E-Commerce ', which I've written under the supervision of  Prof. Harald Sack  (Karlsruhe University) who is one of the directors of the summer school. Thus, I decided to take a chance and to refresh my knowledge about the semantic topics, to network with researchers from the area and at the same time to represent the SpringerNature company by the target audience.  As an outcome I've got very special experience, a lot of lessons learned, great socializing and two awards for  the best research paper  and

1 month in the USA

Incredible, one month is already gone since I came to Palo Alto. The time is going so fast here. So it is probably time me to look back and summarize my first impressions... First impressions My first thought when I came here was: oh my God, I'm in a Hollywood movie. Actually when you live in every European country and you watch an american movie you don't think that the action is happening near your house, because everything is little bit different. Other houses, other cars, other policemen and even post boxes. When you are here you see that everything looks really like in a movie. Same small, very elegant, maintained houses, huge pickups, policemen with their shiny badges and post boxes with a red flag, which rises when a letter is inside. Households differences All kinds of measures are different from Europe. Instead of kilometers - miles, instead of kilograms - pounds, etc. If you will say to an American let us meet up at 17:00 o'clock - he won't

I was waiting for this day since 1 year. After long preparation, visa application, room search and packing I'm sitting in the airport and waiting for my flight. This flight will bring me to the country of thousand opportunities in other part of the world. Incredible, more than 9000 kilometers (5600 miles) is San Francisco from Berlin airport away. My flight will take 14 hours. I was never so far away from home.I don't know what is expecting to me but I hope to be very satisfied with thejorney. To meet new interesting people, learn country and people living here, learn something in my profession and extend my point of view. Leaving comfort zone I want to leave my comfort zone and learn new things. The disadvantage of the comfort zone is that you do all daily things automatically, you don't recognize details and don't feel surrounding environment. To get rid of this situation you should go to the places where you weren't before anddo things you never done. In

Excurse: Introduction to databases

In my previous post I started to explain the SAP Coding Masters Challenge and the assignments, which we had to solve. We should analyse data taken from twitter API to answer different questions. In this post I will tell about the second challenge and make briefly introduction into databases. Second Challenge In the second challenge our teams should solve similar exercises, but this time not with our technologies but with the SAP new HANA database. The challenge was organised to give us the opportunity to get to know this new technology and to work with it. At this point I would like to introduce how the data is stored in conventional databases and how it is different from the SAP HANA. Brief Introduction into Databases Almost every computer program consists of application logic and program data. The data is even more important for the business than logic. It's said that:  the business without application logic adapted to its needs will be lame on both its feet, but wi
