While continuing the study of mahout, it is inevitable to write code that uses the various algorithms stored with it. So I asked a colleague to help out and one option was to start with a java wicket found here: http://blog.jteam.nl/wp-content/uploads/2010/04/taste-getting-started.zip
Using it is quite straightforward. Download the zip file. Unzip it to some folder (say taste-getting-started in the mahout machine). Using Ubuntu’s Terminal application, go to that folder and run mvn package. After packaging is complete, run mvn jetty:run-war. Once the jetty server is up, you can make use of the wicket by browsing http://localhost:8080/taste-getting-started/movies.
Although the above is the straightforward usage of the said wicket, setting it up requires some effort such as
- downloading the MovieLens’ 100K Ratings Data Set: http://grouplens.org/system/files/ml-data_0.zip
- Unzipping it to some other folder.
- Copying u.data to taste-getting-started/src/main/resources/grouplens/100K/ratings
- Copying u.item to taste-getting-started/src/main/resources/grouplens/100K/data
- Executing the initialize_movielens_db.sql using the following command mysql --user=mysqluser --password=mysqlpassword < initialize_movielens_db.sql while at the taste-getting-started/src/main/resources/sql folder.
Oh and if you do not have MySQL yet, install it by issuing the following command sudo apt-get install mysql-server mysql-client.
Hi Shem:
ReplyDeleteI have gone through all the steps that you have mentioned and I have also installed the Eclipse IDE. But I don't know how to run the examples. Could you please help me with it?
Do I have to install the Jetty? Because when I browse the test source files through Eclipse, it cannot find jetty references!
For example org.mortbay..jetty.Connector can not be found, although another code which runs a simple Jetty web server runs and has no problems (a jetty kick start code).
Do I have to make any changes to pom.xml?
And I have no idea how to use that xml find mentioned in http://blog.jteam.nl/2010/04/15/mahout-taste-part-two-getting-started/.
I'm talking about the following xml:
I would really appreciate your help :)
Thank you,
Aidin.
Thanks Aidin for your comment. Apologies too for this late reply as I've been busy at work this past few weeks.
ReplyDeleteI might have failed to actually mention here how I ran the example. Here's how:
at the prompt, I went to the /taste-getting/started/ folder and keyed in mvn package.
After packaging, I keyed in mvn jetty:run-war.
Maven will try to download all needed components.
