Hi,
I am trying to integrate DictionaryAnnotator of UIMA to Solr 4.9.0 to find
gene names from a dictionary. So I made the following changes.
1. I Modified OverridingParamsExtServicesAE.xml file as follow:
<delegateAnalysisEngineSpecifiers>:
...
<delegateAnalysisEngine key="DictionaryAnnotator">
<import name="DictionaryAnnotator"/>
</delegateAnalysisEngine>
...
</delegateAnalysisEngineSpecifiers>:
2. Modified the <flowConstraints> sections for adding DictionaryAnnotator
node:
<fixedFlow>
<node>AggregateSentenceAE</node>
<node>OpenCalaisAnnotator</node>
<node>TextKeywordExtractionAEDescriptor</node>
<node>TextLanguageDetectionAEDescriptor</node>
<node>TextCategorizationAEDescriptor</node>
<node>TextConceptTaggingAEDescriptor</node>
<node>TextRankedEntityExtractionAEDescriptor</node>
<node>DictionaryAnnotator</node>
</fixedFlow>
3. Added org/apache/uima/desc/DictionaryAnnotator.xml
DictionaryAnnotator.xml
4. Added my dictionary to org/apache/uima/desc/dictionary.xml
5.- Generated the file apache-solr-uima-4.9.jar
6. Added Gene to schema.xml.
7.Added the following lines in solrconfig.xml:
<lib dir="../../../contrib/uima/lib" />
<lib dir="../../dist/" regex="solr-uima-\d.*\.jar" />
<lib dir="Path-to/apache-uima/lib" />
<uimaConfig>
<analysisEngine>DictionaryAnnotator</analysisEngine>
<fieldMapping>
<type name="org.apache.uima.DictionaryEntry">
<map feature="gene" field="gene"/>
</type>
</fieldMapping>
</uimaConfig>
<requestHandler name="/update" class="solr.XmlUpdateRequestHandler">
<lst name="defaults">
<str name="update.processor">uima</str>
</lst>
<updateRequestProcessorChain name="uima" default="true">
<processor
class="org.apache.solr.uima.processor.UIMAUpdateRequestProcessorFactory">
<lst name="uimaConfig">
<str name="analysisEngine">DictionaryAnnotator</str>
<bool name="ignoreErrors">false</bool>
<lst name="analyzeFields">
<bool name="merge">false</bool>
<arr name="fields">
<str>text</str>
</arr>
</lst>
<lst name="fieldMappings">
<lst name="type">
<str name="name">org.apache.uima.DictionaryEntry</str>
<lst name="mapping">
<str name="feature">gene</str>
<str name="field">gene</str>
</lst>
</lst>
</lst>
</lst>
</processor>
<processor class="solr.LogUpdateProcessorFactory" />
<processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
But I get the following error message when I am truing to import my
documents:
