"Text mining operators are not visible in RM5"

Hi All,

I installed RM 5 at home PC and also at work place. But installation at work place doesn't have entire text mining operators, where as home installation has all text mining operators. Do I need to make any changes in the application configurations to display?

Kindly advice me on this.

Thanks in advance and regards,
Veeranna Ronad.

    Hi,
    do you have the Text Processing Extension installed on both installations? It can be added by using the integrated update mechanism in the help menu.

    Thanks Sebastian.

    I have updated software from the help menu and now text and web crawl operators are visible.

    But when I wrote web crawl process, I did not get any result. The xml is given below. I want operator to search 'Sachin' text in the URL 'http://www.indiatimes.com'

    XML:
    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="5.0">
      <context>
        <input>
          <location/>
        </input>
        <output>
          <location/>
          <location/>
        </output>
        <macros/>
      </context>
      <operator activated="true" class="process" expanded="true" name="Process">
        <process expanded="true" height="100" width="145">
          <operator activated="true" class="web:crawl_web" expanded="true" height="60" name="Crawl Web" width="90" x="45" y="30">
            <parameter key="url" value="http://www.indiatimes.com/"/>
            <list key="crawling_rules">
              <parameter key="1" value="Sachin"/>
            </list>
            <parameter key="output_dir" value="C:\Documents and Settings\36533\Desktop\x.txt"/>
          </operator>
          <connect from_op="Crawl Web" from_port="Example Set" to_port="result 1"/>
          <portSpacing port="source_input 1" spacing="0"/>
          <portSpacing port="sink_result 1" spacing="0"/>
          <portSpacing port="sink_result 2" spacing="0"/>
        </process>
      </operator>
    </process>

    Hi,
    probably the page obeys the crawling. This might be done in the robots.txt.
