UIMA Annotators

As of August 2011, this page is out of date and nothing links to it; it will be deleted in the future.

UIMA™ Annotators do the real work of extracting structured information from unstructured data. You can write your own annotators, use the annotators available here, or find UIMA annotators on the web, often at various repositories.

Several annotators are available as part of Apache UIMA; they are packaged up into one downloadable package. You can access the source for the annotators in the SVN repository at https://svn.apache.org/repos/asf/uima/sandbox/trunk/.

The annotators available here are:

• Whitespace Tokenizer Annotator
• Snowball Annotator
• Regular Expression Annotator
• Hidden Markov Model Tagger Annotator
• BSF Annotator. BSF stands for the Java Bean Scripting Framework; this annotator allows you to write annotators using scripting languages supported by that framework.
• Dictionary Annotator
• OpenCalais Annotator - an experimental annotator that uses the OpenCalais service to do the annotations.
• Lucene CAS indexer (Lucas)
• Concept Mapper Annotator
• Configurable Feature Extractor (CFE)
