  Hi Ema,
  this is quite simple: Just select the Cosine Simularity in one of the clustering operators supporting different distance measures. An example:

  <operator name="Root" class="Process" expanded="yes">
      <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
          <parameter key="number_examples"	value="1000"/>
          <parameter key="number_of_attributes"	value="2"/>
          <parameter key="target_function"	value="three ring clusters"/>
      </operator>
      <operator name="AgglomerativeClustering" class="AgglomerativeClustering">
          <parameter key="measure_types"	value="NumericalMeasures"/>
          <parameter key="numerical_measure"	value="CosineSimilarity"/>
      </operator>
      <operator name="FlattenClusterModel" class="FlattenClusterModel">
      </operator>
      <operator name="ClusterModel2ExampleSet" class="ClusterModel2ExampleSet">
      </operator>
  </operator>
  

  Greetings,
    Sebastian
