Excerpt: Google has put information about the Youtube Symphony Orchestra on its homepage! Whatch yourself: After Thomas recommended reading a paper about trending topics in twitter where it was discovered that trends can be strongly influenced by external factors (media, news) I went right away to twitter looking for the #ysto. Of course I was not surprised that it was already trending on the twitter homepage. After searching for the hashtag an leaving the result page as it was for about 15 minutes Twitter told me that there where 1754 new tweets since my last search! If I find the time I will…

Excerpt: Linked open data or the web of data is the main concept and idea of the semantic web proposed by Tim Berners-Lee. The semantic web is often also referred to as web3.0. But what is the difference of the Internet as we know it by now and the web of data? On the Internet there are hypertext documents which are interlinked to each other. As we all know search engines like Google use the hyperlinks to calculate which websites are most relevant. A hyper text document is created for humans to read and understand. Even though Google can search those…

Excerpt: After Eli’s talk on TED and my recent article about the filter bubble I decided to dig a little deeper into Facebook’s EdgeRank algorithm, which decides what Updates appear in your news feed. I found some more scientific background on how EdgeRank really works. Even though EdgeRank was first mentioned on Facebook F8 Live on April 21st in 2010 it is already mentioned in a footnote of the scientific paper “All friends are not equal: using weights in social graphs to improve search” by Sudheendra Hangal, Diana MacLean, Monica S. Lam and Jeffrey Heer all from Computer Science department at…

Excerpt: Just today an interesting story came up on a German news site which goes back to Eli Pariser’s (Homepage, follow @Twitter ) talk on TED about a thing he calls the Filter Bubble and how personalization is changing the Internet. Before commenting on his talk I want to personally thank him to use his reputation and start a discussion on such a fundamental and important topic! UPDATE most likely you are looking for my list of almost 57 signals google might use to filter I had a short Mail conversation with Eli. He asked me to temporarly remove his TED talk since…

Excerpt: Fans are the most valuable asset a musician has. Without fans there won’t be sales of an album or the possibility to hold concerts. Therefore a musician should always care about the interaction with his fans. On one hand the musician has to protect himself since die hard fans might have the tendency to become stalkers. On the other hand the band has an interest to be able to talk (which means to spread information) to as many fans as possible. Taking good care of your fans is probably a science by itself and I strongly recommend every musician to read…

Excerpt: This is the first part of a series of articles about the perfect band website. It consits of one very important aspect of a band’s website which would be SEO also know as search engine optimization. There are some great resources on the Web about all the technical stuff related to search engine optimization. That is why I will not talk about how to craft your titles, headings and sites structure. I assume that you are a musician or record label working together with a partner that is responsible for your web presence. This Article is supposed to help you to…

Excerpt: In this article I explain how a music band in my opinion should react to all those illegal downloads on the Internet. First of all it is important to understand that no one will be able to change the people and make them stop downloading music on the Web and start buying records again. After Napster went down people found new ways of sharing music. So the question is not: “How to fight illegal downloads?” but rather “How to make the best out of them?” 4 different approaches: We have seen all kinds of different reactions. The most frequent reaction is anger…

Excerpt: Wikipedia is an amazing data set to do all different kinds of research which will go far beyond text mining. The best thing about Wikipedia is that it is licensed under creative common license. So you are allowed to download Wikipedia and use it in any way you want. The articles have almost no spelling mistakes and a great structure with meaningful headings and subheadings. This makes Wikipedia to a frequently used data set in computer science. No surprise that I decided to download and examine Wikipedia. I first wanted to gain experience in natural language processing. Furthermore I wanted…

Excerpt: Recently there was a lot of news on the Web about IBM’s natural language processing system Watson. As you might have heard right now Watson is challenging two of the best Jeopardy players in the US. A lot of news magazines compare Watson with Google which is the reason for this article. Even though the algorithms behind Watson and Google are not open source still a lot of estimates and guesses can be made about the algorithms both computer systems use in order to give intelligent answers to the questions people ask them. Based on this guesses I will explain…

Excerpt: Collective intelligence is a phenomenon that existed in human society for many years. The British mathematician Francis Galton basically discovered collective intelligence when he found out, after averaging all individual guesses, that a crowd of 787 visitors at a county fair indeed accurately guessed the weight of an ox. In his blog Ryan Tomayko provides a text copy of the original article vox populi that appeared in the scientific journal Nature on on March 07, 1907.. In fact, collective intelligence is such a significant issue (particularly on the Internet) that I will devote a whole section of my blog to this…
