2. Documentation

    2.1 Data format

    	Data adheres to the following rules:

    	* Data files contain one or more sentences separated by a
	  blank line.

    	* A sentence consists of one or tokens, each one starting on a
	  new line.

    	* A token consists of ten fields described in the table
	  below. Fields are separated by one tab character.

	* All data files will contains these ten fields, although only
          the ID, FORM, CPOSTAG, POSTAG, HEAD and DEPREL columns are
          guaranteed to contain non-underscore values for all
          languages.

	* Data files are are UTF-8 encoded (unicode).


	Field 1: ID 	

	    Token counter, starting at 1 for each new sentence.

	Field 2: FORM

	    Word form or punctuation symbol

	Field 3: LEMMA 	

	    Stem of word form. Not available for Swedish, so contains 
	    always an underscore.

	Field 4: CPOSTAG 

	    Coarse-grained part-of-speech tag; see the html
	    documentation.

	Field 5: POSTAG 	

	    Fine-grained part-of-speech tag. Not available for
	    Swedish, so identical to the coarse-grained part-of-speech

	Field 6: FEATS 	

	    List of set-valued syntactic and/or morphological
	    features.  Not available for Swedish, so this is always an
	    underscore
	
	Fields 7: HEAD 	

	    Non-projective head of current token, which is either a
	    value of ID or zero ('0')
	
	Field 8: DEPREL 	

	    Dependency relation to the non-projective-head, which is
	    'ROOT' when the value of HEAD is zero; see html
	    documentation for the set dependency relations.

	Field 9: PHEAD 	

	    Projective head of current token, which is always an
	    underscore because it is not available from the Swedish
	    treebank

	Field 10: PDEPREL 

	    Dependency relation to projective head, which is always an
    	    underscore, because it is not available from the Swedish
    	    treebank.
    
    2.2 Text
