KPWr (Polish Corpus of Wrocław University of Technology, pl. Korpus Języka Polskiego Politechniki Wrocławskiej) is a corpus of written and spoken documents available on the Creative Common license. The texts are divided into 14 categories (blogs, science, stenographic recordings, etc.). The documents are annotated on the level of chunks and selected predicate-argument relations, named entities, relations between named entities, anaphora relations and word senses.

Content

The corpus is manually annotated on the following layers:

  • shallow syntax: syntactic chunking and selected inter-chunk syntactic
  • relations,
  • named entities and selected semantic relations between them,
  • anaphora (limited to the identity-of-reference type),
  • word senses (for selected lexemes).

The corpus is stored in CCL (*.xml) and REL (*.rel.xml) files, for format specification please consult the following site: CCL_format.

Note: the progress of annotation is different across the layers. Not all documents have been annotated on all layers.

The following files contain a list of documents annotated on the corresponding annotation layer:

index_chunks.txt syntactic chunking,
index_chunks_rel.txt inter-chunk syntactic relations,
index_names.txt named entities,
index_names_rel.txt semantic relations between named entities,
index_anaphora.txt anaphora,
index_wsd.txt word senses.
