Spanish Gigaword First Edition is a comprehensive archive of newswire text data that has been acquired over several years by the Linguistic Data Consortium (LDC) and contains over 750 million tokens spanning approximately 2.7 million documents. Although this is the first edition of the Spanish Gigaword Corpus, some of the data included here has been released previously in other LDC corpora.

The three distinct international sources of Spanish newswire in this edition, and the time spans of collection covered for each, are as follows:

  • Agence France-Presse, Spanish Service (afp_spa) May 1994 - Dec 2005
  • Associated Press Worldstream, Spanish (apw_spa) Nov 1993 - Dec 2005
  • Xinhua News Agency, Spanish Service (xin_spa) Sep 2001 - Dec 2005


The overall totals for each source are summarized below. The "K-wrds" figures are simply the number in thousands of whitespace-separated tokens of all types after all SGML tags are eliminated.

Source K-wrds #DOCs
AFP_SPA 393354 1382679
APW_SPA 263225 886998
XIN_SPA 94459 388561
TOTAL 751038 2658238

Most of the text data (all of AFP_SPA, most of APW_SPA) were received at LDC via dedicated, 24-hour/day electronic feeds (leased phone lines in the case of APW_SPA, a local satellite dish for AFP_SPA). These 24-hour transmission services were all susceptible to "line noise" (occasional corruption of text content), as well as service outages both at the data source and at our receiving computers. Usually, the various disruptions of a newswire data stream would leave tell-tale evidence in the form of byte values falling outside the range of printable ASCII characters, or recognizable patterns of anomalous ASCII strings.

All the XIN_SPA data, and the portion of APW_SPA data beginning with 200406, were received as bulk electronic text archives via internet retrieval. As such, they were not susceptible to modem line-noise or related disruptions, though this does not guarantee that the source data are free of mishaps. More detailed information can be found in the included documentation.
