Description

The Webis Gmane Email Corpus 2019 is a dataset of more than 153 million parsed and segmented emails crawled between February and May 2019 from gmane.io covering more than 20 years of public mailing lists. The dataset has been published as a resource at ACL 2020.

The dataset comes as a set of Gzip-compressed files containing line-based JSON in the Elasticsearch bulk format. Each data record consists of two lines:

{"index": {"_id": "<urn:uuid:c1d95e4b-0f43-46c7-a99e-c575d1d8e1ce>"}}
{"headers": {"header name": "header value", ...}, "text_plain": "plaintext body", "lang": "en", "segments": [{"end": 99, "label": "paragraph", "begin": 0}, ...], "group": "gmane group name"}

The first line is the Elasticsearch index action with a document UUID, the second one the actual parsed email with a (reduced and anonymized) set of headers, the detected language, the original Gmane group name and the predicted content segments as character spans. The Gzip files are splittable every 1,000 records (line pairs) for parallel processing in, e.g., Hadoop.

Available email headers are:

  • message_id
  • date (yyyy-MM-dd HH:mm:ssZZ)
  • subject
  • from
  • to
  • cc
  • in_reply_to
  • references
  • list_id

Available segment classes are:

  • paragraph
  • closing
  • inline_headers
  • log_data
  • mua_signature
  • patch
  • personal_signature
  • quotation
  • quotation_marker
  • raw_code
  • salutation
  • section_heading
  • tabular
  • technical
  • visual_separator
