Hi, I don't know about DKPro, so someone more familiar with its conventions could respond.
UIMA supports a decoupling of resources, shared among annotators running in some pipeline. I'm guessing you're asking about this mechanism, but before proceeding, there's nothing preventing you from implementing an annotator (let's call it the spelling corrector annotator) which could load a dictionary (let's say, specified by a configuration parameter), and then have some mechanism to "reload it", if it changes. This link in the UIMA Reference manual describes Resources: https://uima.apache.org/d/uimaj-2.10.2/references.html#ugr.ref.resources See also the Javadocs for SharedResourceObject https://uima.apache.org/d/uimaj-2.10.2/apidocs/org/apache/uima/resource/SharedResourceObject.html These have a "load" method which the user is supposed to implement to cause the resource to be "loaded". Typically, if the resource, for example, implemennts a hashmap, the load might read some external file and initialize the hashmap from that. The implementation of the load method is the responsibility of the resource implementer. UIMA will instantiate the resource class, and call the load method, once. One possibility would be to have your spelling annotator check "every so often" to see if the on-disk version has changed, and if so, call the load method again. If you consider doing this, remember that your annotator might (in some deployments) be "scaled up" in multiple Java threads, so you might need to do this under a synchronization lock. Does this help? There may be more conventions / built-in ways that DKPro has for this scenario.
