HCIR 2012

A tweet from RiparianData caught my eye the other day:

I built getvouched.com with this idea of “expert and expertise discovery” using skill based vouching adjusted by the distance from searcher to target as a way to find rank. So I dug in and found out that Human-computer Information Retrieval (HCIR) combines research from the fields of human-computer interaction (HCI) and information retrieval (IR), placing an emphasis on human involvement in search activities.

The HCIR challenge for this years symposium includes “hiring,” “assembling a conference program,” and “finding people to deliver patent research or expert testimony” as summarized by Patrick Durusau.

Batch Importer – Part 3

At the end of February, we took a look at Michael Hunger’s Batch Importer. It is a great tool to load millions of nodes and relationships into Neo4j quickly. The only thing it was missing was Indexing… I say was, because I just submitted a pull request to add this feature. Let’s go through how it was done so you get an idea of what the Neo4j Batch Import API looks like, and in the next blog post I’ll show you how to generate data to take advantage of it.

MadCoderTV is live on Roku

I’ve had a Roku streaming player for my TV for a few years now and a few months ago I got interested in how it actually worked. I started seeing more channels pop-up and I thought how hard could it be to put one up? So I found their SDK, grabbed their sample application and after a few tweaks, some nice artwork and finding content, it was approved.

Why go through the trouble of doing this to watch videos on my TV when I can just watch them on the laptop? One word… Distraction.

If a video is more than 3 to 5 minutes long, there is a good chance I won’t make it all the way through. It’s hard to sit still when you have the full power of your laptop and the internet at your fingertips. On the TV, as long as there are no commercials, I’m pretty much going to just sit there and watch. Maybe it is some mild form of ADD, maybe it’s normal.

Batch Importer – Part 1

Data is everywhere… all around us, but sometimes the medium it is stored in can be a problem when analyzing it. Chances are you have a ton of data sitting around in a relational database in your current application… or you have begged, borrowed or scraped to get the data from somewhere and now you want to use Neo4j to find how this data is related.

Michael Hunger wrote a batch importer to load csv data quickly, but for some reason it hasn’t received a lot of love. We’re going to change that today and I’m going to walk you through getting your data out of tables and into nodes and edges.

Let’s clone the project and jump in.

Chicago Graph DB Meet-Up

We had our first Graph Database Meet-up in Chicago yesterday!

16 Graphistas came out to learn more about the craft and get an introduction to Neo4j. Ryan Briones from Groupon gave us a venue and helped host the event. No worries if you missed it, your next chance to learn more about Neo4j is coming up on Tuesday February 7th @ 6pm, when Prasanna Pendse will share his experiences with Neo4j at ChicagoRuby: Downtown.

Our next Chicago Graph DB meet-up is tentatively scheduled for February 29th @ 6 pm. This will be a hands-on meet-up. I’ll help you get started with either Neo4j on your laptop or in the cloud with Heroku. We’ll create a few graphs, learn some basic traversals and get comfortable with Neo4j. I’ll have a GitHub repository graph for us to play with and see how you are connected to Kevin Bacon (err I mean Linus Torvalds). He is the center of the GitHub universe right? Right? We’ll let’s find out.

The slides of our first meet-up are available below:
