Hi All, I am trying to use the ConceptMapper add on to assign a SemClass feature to tokens. I am getting the following error:
SEVERE: ConceptMapper SEVERE: FeatureList[1] 'SemClass' specified, but does not
exist for type: org.apache.uima.conceptMapper.DictTerm
I configured FeatureList and AttributeList in ConceptMapperOffsetTokenizer.xml
as given below:
<nameValuePair>
<name>AttributeList</name>
<value>
<array>
<string>canonical</string>
<string>SemClass</string>
</array>
</value>
</nameValuePair>
<nameValuePair>
<name>FeatureList</name>
<value>
<array>
<string>DictCanon</string>
<string>SemClass</string>
</array>
</value>
</nameValuePair>
<nameValuePair>
<name>ResultingAnnotationName</name>
<value>
<string>
org.apache.uima.conceptMapper.DictTerm
</string>
</value>
</nameValuePair>
Here is my simplified dict.xml file
<synonym>
<token canonical="grocery" SemClass="category">
<variant base="grocery"/>
</token>
</synonym>
I debugged the problem and found that it is looking for the SemClass feature in
resultAnnotationType which DictTerm. But actually, the SemClass is not a
feature in DictTerm type.
resultEnclosingSpan =
resultAnnotationType.getFeatureByBaseName(resultEnclosingSpanName);
if (resultEnclosingSpan == null) {
logger.logError(PARAM_ENCLOSINGSPAN + " '" + resultEnclosingSpanName
+ "' specified, but does not exist for type: " +
resultAnnotationType.getName());
throw new AnnotatorInitializationException();
}
I just started using UIMA, so I don't understand the complete architecture yet.
Could any of you point me to the right direction ? Thanks a lot in advance.
