   <p>The Polish Coreference Corpus (PCC) is a large manually annotated corpus of general Polish coreference built upon the National Corpus of Polish. With its over 1800 documents from 14 text genres, containing about 540,000 tokens, 180,000 mentions and 128,000 coreference clusters, the PCC is among the largest coreference corpora in the international community. It has some novel features, such as the annotation of the quasi-identity relation, inspired by Recasens’ near-identity, as well as the mark-up of semantic heads and dominant expressions. It shows a good inter-annotator agreement and is distributed under an open license.</p>
   <p>The texts of the corpus were manually annotated in a so-called series approach in which each document was first reviewed by one human annotator, and his/her results were further corrected and validated by an adjudicator. The annotation covered indicating mention borders, semantic mention heads, marking quasi-identity relations, clustering coreferential mentions and indicating dominant expressions in each cluster. In the last version of the corpus the annotation of bridging relations was also added.</p>
  </projectDesc> 

  <samplingDecl>
   <p>The PCC consists of two main subcorpora: 1745 “short” texts, i.e. containing 250–350 segments in length, constituting fragments of longer documents (but always full consecutive paragraphs) and 21 “long” texts – complete documents. In the latest correction of the short text subcorpus it was noted that some texts are composed of shorter separate notes so they were split and moved into a separate subcorpus of 62 “very short” texts.</p>
   <p>“Short texts” and “very short texts” are plain text fragments of randomly selected documents (of certain types, to create a balanced representation) from NKJP. For each document, paragraph sequences were also extracted randomly. Short text types in PCC correspond to NKJP text types and text type representation is similarly balanced, matching the 1-million-word manually annotated subcorpus of NKJP.</p>
   <p>“Long texts” are complete texts from the so-called Rzeczpospolita Corpus (see http://www.cs.put.poznan.pl/dweiss/rzeczpospolita) – press articles retrieved in HTML from the online edition of Rzeczpospolita, one of the most prominent daily newspapers in Poland. The length of the selected texts varies from 1000 to 4000 segments. Collection of data, ultimately converted to plain text, has been performed semi-randomly (with interviews or documents combining a series of short press notes removed from the selection). Based on the metadata present in the original HTML (DZIAL attribute) 7 most common text domains in the corpus were determined and 3 texts representing each domain have been included into PCC.</p>
