Some time ago I had some blog posts introducing some of the basic Statistical function available in Oracle. Here are the links to these.
Over the past while I've been working a lot with text strings. Some of these have been short in length like tweets from Twitter, or longer pieces of text like product reviews. Plus others of various lengths.
In all these scenarios I have to break up the data into individual works or Tokens.
The examples given below illustrate how you can take a string and break it into its individual tokens. In addition to tokenising (more...)
For a few years now I (and I'm sure you have too) have heard about and followed the various Oracle User Group tours that OTN arranges/facilitates. A tour consists of a number of Oracle User Groups in a region coordinating together to have their conferences organised so that they can get speakers from across the world to come and present.

The conference kind of started on the Wednesday. It seemed like most of the speakers from across Europe and USA were getting into Helsinki around lunch time. Heli had arranged to be a tour guide for the afternoon and took us to see (more...)
In ORE there are a number ways to get you R scripts to run in parallel in the database. One way is to enable the Parallel option in ORE. This is what will be shown in this post. There are other methods of running various ORE commands/scripts in parallel. With these the scripts are divided out and several parallel R processes are started on the server.
But what if you want to use the database (more...)
In previous posts I gave the steps required to install Oracle R Enterprise on your Database server and your client machine.
One of the steps that I gave was the initial set of Database privileges that the DB needed to give to the RQUSER. The RQUSER is a little bit like the SCOTT/TIGER schema in the Oracle Database. Setting up the RQUSER as part of the installation process allows you to test that you can (more...)
