  • *Introduction*

    2009 CoNLL Shared Task Part 2, LDC Catalog Number LDC2012T04 and ISBN 1-58563-611-8, contains the Chinese and English trial corpora, training corpora, development and test data for the 2009 CoNLL (Conference on Computational Natural Language Learning) Shared Task Evaluation. The 2009 Shared Task developed syntactic dependency annotations, including the semantic dependencies model roles of both verbal and nominal predicates.

    The Conference on Computational Natural Language Learning (CoNLL) is accompanied every year by a shared task intended to promote natural language processing applications and evaluate them in a standard setting. The 2004 and 2005 CoNLL shared tasks were dedicated to semantic role labeling (SRL) in a monolingual setting (English). In 2006 and 2007, the shared tasks were devoted to the parsing of syntactic dependencies and used corpora from up to thirteen languages. In 2008, the shared task focused on English and employed a unified dependency-based formalism and merged the task of syntactic dependency parsing and the task of identifying semantic arguments and labeling them with semantic roles that data has been released by LDC as 2008 CoNLL Shared Task Data (LDC2009T12). The 2009 task extended the 2008 task to several languages (English plus Catalan, Chinese, Czech, German, Japanese and Spanish). Among the new features were comparison of time and space complexity based on participants input, and learning curve comparison for languages with large datasets.

    The 2009 shared task was divided into two subtasks:

    * parsing syntactic dependencies
    * identification of arguments and assignment of semantic roles for each predicate
    2009 CoNLL Shared Task Part 1 (LDC2012T03) contains the Catalan, Czech, German and Spanish task data and is also available through LDC.

    *Data*

    The materials in this release consist of excerpts from the following corpora:

    * Penn Treebank II (LDC95T7) (English): over one million words of annotated English newswire and other text developed by the University of Pennsylvania
    * PropBank (LDC2004T14) (English): semantic annotation of newswire text from Treebank-2 developed by the University of Pennsylvania
    * NomBank (LDC2008T23) (English): argument structure for instances of common nouns in Treebank-2 and Treebank-3 (LDC99T42) texts developed by New York University
    * Chinese Treebank 6.0 (LDC2007T36) (Chinese): 780,000 words (over 1.28 million characters) of annotated Chinese newswire, magazine and administrative texts and transcripts from various broadcast news programs developed by the University of Pennsylvania and the University of Colorado
    * Chinese Proposition Bank 2.0 (LDC2008T07) (Chinese): predicate-argument annotation on 500,000 words from Chinese Treebank 6.0 developed by the University of Pennsylvania and the University of Colorado
    In addition, an archive of all of the uploaded data from the participants is included in the eval-data folder. Users should note that not all data indicated in the individual READMEs is included in this release and neither are some of the corresponding DTDs for the XML. Additionally, all data is presented in its uncompressed form for ease of use. Within the user eval-data folder, the two folders marked bad contain references to data from languages included in Part 1 of this release as well as to Japanese data. Japanese data is not included in this release.
