As I said yesterday I have been busy over the last months producing content so here you go. For related work we are most likely to use neo4j as core data base. This makes sense since we are basically building some kind of a social network. Most queries that we need to answer while offering …

Foundations of statistical natural language processing Review of chapter 1
Due to the interesting results we found by creating Typology I am currently reading the related work about query prediction and auto completion of scentences. There is quite some interesting academic work available in this area of information retrieval. While reading these papers I realized that I am not that strong in the field of …
Neo4j based Typology also awarded top 90 at Google Science fair.
Yesterday I shared the good news about Till and Paul who have been awarded one of the top 5 projects at the German federal competition Young scientists. Today the good news continues. Together with more than 1000 competitors they did also submit the project to the Google Science Fair. And guess what! Google likes graph …
Typology using neo4j wins 2 awards at the German federal competition young scientists.
Two days ago I arrived in Erfurt in order to visit the federal competition young scientists (Jugend Forscht). I reported about the project typology by Till Speicher and Paul Wagner which I supervised over the last half year and which already won many awards. Saturday night they have already won a special award donated by …

Time lines and news streams: Neo4j is 377 times faster than MySQL
Over the last weeks I did some more work on neo4j. And I am ready to present some more results on the speed (In my use case neo4j outperformed MySQL by a factor of 377 ! That is more than two magnitudes). As known one part of my PhD thesis is to create a social newsstream …
Analysing user behaviour in internet communities
Yesterday Julia Preusse – who started her PhD studies at WeST just a month before I did – had a talk about her research interests. She is interested in communities and the behaviour of users in discussions. I thought she was having some interesting ideas. That is why I asked her for a meeting today. …
Neo4j Graph Database vs MySQL
For my social news stream application I am heavily thinking about the right software to support my backend. After I designed a database model in MySQL I talked back to Jonas and he suggested to search for a better suiting technology. A little bit of research brought me to a Graph database called Neo4j. After …
Social news streams – a possible PhD research topic?
It is two months now of reading papers since I started my PhD program. Enough time to think about possible research topics. I am more and more interested in search, social networks in general and social news streams in particular. It is obvious that it is becoming more and more important to aggregate news around …
Facebook User Search: Ever wondered how Facebook is more social than others?
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 …
