1. What is UIMA Ruta?

Apache UIMA Ruta™ is a rule-based script language supported by Eclipse-based tooling. The language is designed to enable rapid development of text processing applications within Apache UIMA™. A special focus lies on the intuitive and flexible domain specific language for defining patterns of annotations. The Eclipse-based tooling for Ruta, called the Ruta Workbench, was created to support the user and to facilitate every step when writing Ruta rules. Both the Ruta rule language and the Ruta Workbench integrate smoothly with Apache UIMA.

2. Major Changes in this Release

This release contains changed in the analysis engine descriptor and the type system descriptors and therefore requires an update of the Ruta projects. This can be accomplished for example by right-click on the Ruta project, selecting "UIMA Ruta" and then "Update Project".

• The analysis engine is able to generate debug information about inlined rules which includes also an extension of the ruta type system.
• Type expressions in dot notation for annotation expressions a new supported: a1:ANY a2:ANY{a1.type==a2.type -> Type};
• Matching on string literals is no more restricted to single RutaBasic annotations, e.g., it is now possible to write: "This is a test"{-> Test};
• Dictionary matching is now more robust concerning white spaces in the word list. The parameter dictRemoveWS is now also set to true by default.
• Fixed anchors at composed rule elements.
• Labels at macro actions are supported now.
• Fixed several bugs.

UIMA Ruta Workbench:
