Source: The Stanford GraphBase. A network can be represented by an adjacency matrix, where each cell ij represents an edge from vertex i to vertex j. Here, vertices represent characters in a book, while edges represent co-occurrence in a chapter. Given this two-dimensional representation of a graph, a natural visualization is to show the matrix! However, the effectiveness of a matrix diagram is he
Last month I shared details of the locations where I was planning to deliver my “Introduction to Data Visualisation” training courses during the first half of 2012. I’m delighted to announce more details about the schedule, specifically the dates of the events. This is the list of locations I will be visiting and the dates on which I will be delivering the courses. Venue details will be confirmed
So far we’ve learned how to get Neo4j up and running with Neography, how to find friends of friends and degrees of separation with the Neo4j REST API and a little bit of the Gremlin and Cypher languages. However, all we’ve seen is text output. We haven’t really “seen” a graph yet, but that’s about to change. Vouched holds a graph of skill specific recommendations people have made to each other and
Open access is the idea that scholarship should be accessible to all. Many believe that we should require publicly funded researchers to make their work available to the public. That is, if some professor discovers a new algorithm or a new remedy while on a government grant, you should be able to download and read the paper freely. To non-scientists, open access may sound like a socialist utopia.
We are pleased to announce the first release of Kafka from the Apache incubator. Kafka is a distributed, persistent, high throughput messaging system for collecting and delivering a high volume of data with low latency. The 0.7.0 release adds compression and mirroring features. At LinkedIn, Kafka is primarily used for tracking the huge volume of activity events generated by the website. These acti
Introducing DataFu: an open source collection of useful Apache Pig UDFs At LinkedIn, we make extensive use of Apache Pig for performing data analysis on Hadoop. Pig is a simple, high-level programming language that consists of just a few dozen operators and makes it easy to write MapReduce jobs. For more advanced tasks, Pig also supports User Defined Functions (UDFs), which let you integrate custo

Relational algebra is a theory for manipulating relations whose power is equivalent to SQL and relational calculus. Remarkably, relational algebra has only six primitive operations. I define the six primitives below, but if you're looking for a comprehensive work on relational theory, particularly as it relates to modern databases, I recommend Date's SQL and Relational Theory: Relations in Unix Ma
