Data format

• Data are stored in UTF-8 encoded XML format.
• Design principles
• Reduced inventory of node names.
• Attributes are atomic.
• Attributes describe only the node they depend of.
  
• There is no redundancy in the data.
• Adding new annotation levels/values is fast and
  easy.
• Annotation time has been reduced by a whole 50.

4
Annotation interface

• Installation requirements
• Java 1.5 o higher.
• SWT Java graphic library (included in our package
  for Windows XP).
• Otherwise, the graphic library can be obtained
  with the free Eclipse package.

5
Annotation interface

• Description
• The interface is organized in a series of screens
  where specific data for each annotation level are
  shown.
• The interface highlights all nodes capable of
  being annotated, and the sentences which have not
  been marked yet, in order to make the annotators
  work easier.

6
Annotation interface

• The system allows for the addition of external
  tools for specific annotation levels
• WordNet
• Coreference

7
Future improvements

• Making the tool available from the Internet,
  adapting it to Linux and Mac environments.
• Implementing corpus query methods from the
  interface.
• Implementing statistical corpus description
  methods.
• Adding tools to handle verbal and nominal
  lexicons.
• Adding semiautomatic methods and machine learning
  functions for the partial annotation of corpora.
