AW: HashMap as type feature
Dear Richard,
to use StringStringMapEntry, needn't it subclass TOP or FeatureStructure? Is it
possible to store an arbitray object into a CAS?
Cheers,
Armin

Hi,
you could define a feature structure e.g.
StringStringMapEntry {
String key
String value
}
and store these in an FSList. Then, write additional convenience code around
that which transforms this to/from a MapString, String.

Re: HashMap as type feature
TOP or AnnotationBase (which contains view-related code) would be the
appropriate types, I believe.
It is not possible to store arbitrary objects in the CAS.

AW: HashMap as type feature
Hi Thomas, thanks for your answer. Using HashMap, does the n-th element of keySet() always corresponds to the n-th element of values()? Is this a defined behavior in Java?

Oktober 2013 18:53 An: user@uima.apache.org Betreff: Re: HashMap as type feature Armin, Our team does this with an annotation type designed to store feature vectors for Machine Learning applications. In this case we use a StringArray feature for the keys and a StringArray feature for the values. The StringArrays are pulled from a HashMapString, String vector variable and inserted into the features with the following code: int size = vector.size(); StringArray keys = new StringArray(jcas, size); StringArray values = new StringArray(jcas, size); keys.copyFromArray(vector.keySet().toArray(new String[size]), 0, 0, size); values.copyFromArray(vector.values().toArray(new String[size]), 0, 0, size); Retrieving the values is fairly straightforward. If you are using a static annotation type it can be as simple as: StringArray keys = vector.getKeysArray(); If you parameterize our annotation type in the annotator you can use the name of the feature to get a Feature object reference then pull the StringArrays like so: Type annotationTypeObj = aJCas.getRequiredType(com.my.Annotation); //parameter is the canonized name of the Annotation type Feature keyFeature = annotationTypeObj.getFeatureByBaseName(keyFeatureName); //the actual name of the feature storing the key StringArray reference Feature valuesFeature = annotationTypeObj.getFeatureByBaseName(valuesFeatureName); //the name of the values feature //Get a list of the annotation objects in the CAS then iterate through the list, for each annotation 'a' do the following to retrieve the keys and values StringArray keys = (StringArray) vector.getFeatureValue(keysFeature); StringArray values = (StringArray) vector.getFeatureValue(valuesFeature); If necessary you can retrieve a String[] from the StringArray FeatureStructure by calling the .toArray() method such as: String[] keysArray = keys.toArray(); Let me know if you have any questions.

Re: HashMap as type feature
Armin, Yes. Extracting the key set results in an array wherein the n-th element of the key array corresponds to the n-th element of the values array. That is part of how the hash map is handled in Java. Even if you implemented your own sorting algorithm for insertion the value would get inserted with the key and the corresponding key and values arrays would still match. The only caveat would be if you decided to manipulate the keys array independently after getting it from the HashMap.

XmiCasSerializer error in UIMA-AS
Hi all, I have an AE that produces the error below when deployed as a UIMA-AS 2.4.0 service. The same AE as part of a UIMA 2.4.2 CPE or a uimafit 2.* pipeline does not produce any errors and works as expected. Among other things, this AE uses ruta rules to process the CAS. When the rules are not used, the AE works as expected in both UIMA and UIMA-AS. I have tried to log all annotations generated by the AE when the rules are used and just before the AE processing is finished. The annotations seem the same in both the UIMA and the UIMA-AS processing scenarios. Does anyone have hints on what the cause of this might be or how I should proceed in debugging?

You could also use the entrySet which gives you all the key/value pairs. -- Richard On 17.10.2013, at 16:43, armin.weg...@bka.bund.de wrote: Hi Thomas, thanks for your answer.
