Try using macros, e.g.:

Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

Hi there,

I started using Rapidminer 5 recently, and I want to Cluster the content of around 100 Blogs.

I set up the tool to cluster the content of one homepage. I generate the data with the function Read RSS Feed. My question is if there is a possibility to use an excel list with the url's of all the blog i want to store the data instead of typing every single url in the function Read RSS Feed.

Thanks a lot for your help,

HSG_Miner

fixed this error by installing the java developer's kit. Saw this tip after posting this.

This is solved.

I am getting a message when I attempt to open the rapidminer.app file indicating that I have a non-current release of Java. I just happened to update it today and the Java site verifies that I have version 7 installed.

Can you please review ?  The app is sensing that I have version 6 installed.

Thank you !

I'd first think of concatenating "article" and "action" (23_0, 92_0, 40_2, ...). Then e.g. use the template from your samples repository (samples/processes/01_learner/25_fpgrowth) plus a final "Item Sets to Data" and export the result to excel, where you can filter easily without java coding etc.

Friends:
I am using RM Studio 6 with unrestricted memory on a late model MacBook Pro Retina with 16Gb, quad core i7 with variable Hz from 2.6 to 3.2gHz depending on load and a 1Tb solid state drive, running Mavericks. I use .csv data consisting of up to 100 rows by up to 120 attributes, though I would like to be able to process much larger sets of up to 500,000 rows. Using the 100 row set with 29 attributes I was trying to set up the process by filling in the missing data. No sooner had I selected the proper operator to do this in the operator window than RM developed the spinning color wheel of death (scwd).

The computer itself was not frozen and other software could be run. I could not copy the XML code to put here because once the scwd appears, the only recourse I know of is to forcibly quit the process and that action closes RM without saving the XML for me to copy. The SCWD can also appear during clustering or decision tree analysis.
 
I have three questions: is there a way of saving the XML file once the scwd has appeared so that I can share it here, is the scwd always fatal or is there a way of recovering control of RM,  and are there some aspects of RM that I could check to lower the likelihood of developing the scwd?

Thank you for your consideration.

Hi there,

First of all let me apologize for my poor english. Iīm from germany and english isnīt one of my best skills.
Iīm totally new to RapidMiner and I have to do a little homework for my university. I have to analyse 100k datasets for association rules. Those datasets arenīt really complex, but I have zero experience in working with RapidMiner. One dataset consists of one custommer ID, one article ID and an integer variable between 0 and 2 with the translation: 0 = article was watched, 1 = article was placed in the shopping basket and 2 = article was puchased. Here are some examples:
ID   article   action
1       23        0
1       92        0
1       40        2
2       92        1
2       12        0

In this example customer 1 watched articles 23 and 92 and then bought article 40. Customer 2 put article 92 in his basket und watched article 12. So one customer can only choose one of the three actions for one article. There are no datasets with equal IDīs and equal article IDīs but different action. There will always be just one action for any article a customer looked at. I hope you get the idea of those datasets.
Now I have to find some rules like: If article 23 and article 92 were watched, article 40 was bought. But I have no clou how to find those rules with my RapidMiner community edition 5.3. My datasets are located in an excel file, so I read them and since the FP-Growth algorithm needs binomial attributes, I converted every attribut into binomial. At the end I connected the FP-Growth operator withe the Create Association Rules Operator. But the result I get are totally wrong. They ary like: If Article_ID Then Action or If Acticle_ID and customer_ID Then action. Instead I would like to get rules like: If article_ID = 23 and action = 0, article_ID = 92 and action = 0 then article_ID = 40, action = 2.
Can anybody explain to me how association rules in RapidMiner work? Do I have to transform my datasets or are there any operator configurations I have to do. Please halp me.
Btw. Again, sorry for my bad english.
