Subject: Carrot2 clustering component
Hi,
I am not able to understand the caarot2 clustering component from
http://wiki.apache.org/solr/ClusteringComponent
please provide me more detailed information if someone had already worked on
this. How to run this and use this during search query.
Thanks!
Isha
I had downloaded some jar files compatible with solr1.4 including:
carrot2-core-3.4.2.jar
guava-r05.jar
hppc-0.3.1.jar
jackson-core-asl-1.5.2.jar
mahout-collections-0.3.jar
jackson-mapper-asl-1.5.2.jar
log4j-1.2.14.jar
mahout-math-0.3.jar
simple-xml-2.3.5.jar
And placed them at contrib/clustering/lib
Then changed the solr.config as:
<requestHandler name="standard" default="true">
<!-- default values for query parameters -->
<lst name="defaults">
<str name="echoParams">explicit</str>
<!--
<int name="rows">10</int>
<str name="fl">*</str>
<str name="version">2.1</str>
-->
<!--<bool name="clustering">true</bool>-->
<str name="clustering.engine">default</str>
<bool name="clustering.results">true</bool>
<!-- The title field -->
<str name="carrot.title">headin</str>
<str name="carrot.url">id</str>
<!-- The field to cluster on -->
<str name="carrot.snippet">text</str>
<!-- produce summaries -->
<bool name="carrot.produceSummary">true</bool>
<!-- the maximum number of labels per cluster -->
<!--<int name="carrot.numDescriptions">5</int>-->
<!-- produce sub clusters -->
<bool name="carrot.outputSubClusters">false</bool>
</lst>
<arr name="last-components">
<str>clustering</str>
</arr>
</requestHandler>
<searchComponent name="clustering">
<!-- Declare an engine -->
<lst name="engine">
<!-- The name, only one can be named "default" -->
<str name="name">default</str>
<str
name="carrot.algorithm">org.carrot2.clustering.lingo.LingoClusteringAlgorithm</str>
<str name="LingoClusteringAlgorithm.desiredClusterCountBase">20</str>
</lst>
<lst name="engine">
<str name="name">stc</str>
<str
name="carrot.algorithm">org.carrot2.clustering.stc.STCClusteringAlgorithm</str>
</lst>
</searchComponent>
And then run solr using command:
java -Dsolr.clustering.enabled=true -jar start.jar
Now can you tell me where i am wrong ?????????? what else should i do?????????
