Cornell Wikiconv Dataset

WikiConv is a multilingual corpus encompassing the history of conversations on Wikipedia Talk Pages—including the deletion, modification and restoration of comments. More information is available at: https://github.com/conversationai/wikidetox/tree/master/wikiconv. Distributed together with WikiConv A Corpus of the Complete Conversational History of a Large Online Collaborative Community.

Summary

Organize the conversations of the Wikiconv Dataset to mirror the most up-to-date version of the conversation at the time of data collection. This most up-to-date version of the conversation reflects the “final” state of each utterance (the utterance after all edits at time of data collection have been performed on the utterance) in the conversation.

Dataset Details

Types

Due to Wikipedia’s format and editing style, conversations are just snapshots of a history of edits (or revisions) that take place on a given Talk Page. We parse these revisions, compute diffs, and categorize edits into 5 kinds of ‘actions’ and each utterance is made up of a collection of the following actions:

  • CREATION: An edit that creates a new section in wiki markup.

  • ADDITION: An edit that adds a new comment to the thread of a conversation.

  • MODIFICATION: An edit that modifies an existing comment on a Talk Page.

  • DELETION: An edit that removes a comment from a Talk Page.

  • RESTORATION: An edit (for example, a revert) that restores a previously removed comment.

Utterance-level Information

Each conversational turn on the talk page is viewed as an utterance. For each utterance, we provide:

  • id: A unique identifier assigned by the original WikiConv reconstruction pipeline

  • speaker: Wikipedia user name of the editor

  • conversation_id: ID of the first utterance in the conversation this utterance belongs to

  • reply_to: ID of the utterance to which this utterance replies to (None if the utterance is not a reply)

  • timestamp: Time of the utterance

  • text: Textual content of the utterance

  • type: Type of the action that this comment represents (from one of the five previously defined types)

  • meta: Provided below

Metadata for each utterance includes:

  • is_section_header: Whether the utterance is a conversation “title” or “subject” as seen on the original talk page (if true, this utterance should be ignored when doing any NLP tasks)

  • indentation: Level of indentation of the comment when displayed on the page

  • ancestor_id: For modification, removal, and restoration actions, this provides the id of first creation of the action that was modified, removed, or restored respectively.

  • rev_id: The Wikipedia revision id of the edit from which the action was extracted.

  • parent_id: For modification, removal, and restoration actions, this provides the id of the action that was modified, removed, or restored respectively.

  • toxicity: Score assigned by Perspective API given the content using TOXICITY attribute (only available for English corpus).

  • sever_toxicity: Score given by Perspective API given the content using SEVERE_TOXICITY attribute (only available for English corpus).

  • original: Original Utterance if the original utterance was modified or deleted in any way

  • modification: A list of utterances indicating modification edits on this utterance, ordered by timestamp (earliest first)

  • deletion: A list of utterances (of size 1 unless the utterance was restored and then deleted again) indicating deletion edits on this utterance, ordered by timestamp (earliest first)

  • restoration: A list of utterances (of size 1 unless the utterance was deleted, restored, deleted and restored again) indicating restoration edits on this utterance, ordered by timestamp (earliest first)

Conversation-level Information

Metadata for each conversation include:

  • page_title: The name of the Talk Page where the action occurred.

  • page_id: The Wikipedia id of the page on which the action took place.

  • page_type: The type of the page (primarily talk vs user talk)

  • Example: “287020584.2938.0”: {“page_id”: “378580”, “page_title”: “Eric Harris and Dylan Klebold”, “page_type”: “talk”}

Additional notes

A common use case for the WikiConv corpora might be to combine corpora from different years for further analysis. This is straightforward with the Corpus’s merge functionality, which we demonstrate below.

>>> from convokit import Corpus, download
>>> wikiconv_2003 = Corpus(filename=download("wikiconv-2003"))
>>> wikiconv_2003.print_summary_stats()
Number of Speakers: 9168
Number of Utterances: 140265
Number of Conversations: 91787
>>> wikiconv_2004 = Corpus(filename=download("wikiconv-2004"))
>>> wikiconv_2004.print_summary_stats()
Number of Speakers: 34235
Number of Utterances: 613608
Number of Conversations: 303494
>>> merged_corpus = wikiconv_2003.merge(wikiconv_2004)
WARNING: Multiple values found for Speaker([('name', 'TUF-KAT')]) for meta key: user_id. Taking the latest one found
>>> merged_corpus.print_summary_stats()
Number of Speakers: 41509
Number of Utterances: 753873
Number of Conversations: 392883

Notice that the number of Utterances in the merged corpus is simply the sum of those in the constituent corpora. This is to be expected since the Utterances from these two corpora are from different years and are therefore distinct and non-overlapping.

However, the number of Speakers and Conversations is not the sum of those of the constituent corpora – undoubtedly because some Speakers have made Utterances in both years and because some Conversations took place over 2003 and 2004.
