"Lookup data

Hi there.


I'm new to rapid miner and I have some difficulty for doing some of my case :
1. Lookup value from another data..
Is there any lookup operator like in MS excel or SSIS (MSSQL)? I already try to search for the operator but I didn't find any..

2. Is there any operator or ways to write the data into the XML file?


Thanks,
Felix

    Hi,

    if you want to find out whether there is a certain pattern in your data, you first have to load it to RapidMiner. Once this is done you may use a filter to match to some value or regular expression. Finally there are lots of possibilities to store your findings or proceed using this knowledge processing further actions.
    How does your data look like and what do you want to do with your findings?

    Cheers,

    Hi,

    Thanks for your help, actually I already done it using left join for lookup the data..

    Ohh this is actually the xml data looks like :
    <?xml version="1.0" encoding="utf-8"?>
    <data>
          <contract_id>int</contract_id>
          <amt_financed>decimal</amt_financed>
          <term>int</term>
          <customer>
                <party_id>int</party_id>
                <name>string</name>
                <sex>string</sex>
                <occupation>string</occupation>
                <salary>decimal</salary>
          </customer>
          <supplier>
                <party_id>int</party_id>
                <name>string</name>
                <supplier_segment>string</supplier_segment>
          </supplier>
    </data>
    I need the xml formats to support an object data type like in the example (customer might have multiple data)..
    And I need the xml perfectly the same format because I need it to upload to the system, which is only accept that kind of format..

    Thanks :)

    Hi Felix,

    there is no fully customizable XML output generator. But nevertheless you may build a process that does what you need. Please install the text mining extension for RapidMiner (Help -> Udates and Extensions, search for text mining) and open the following process, which shows how yours may look like: 

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="6.0.008">
      <context>
        <input/>
        <output/>
