What is InternetArchiveBot (IABot)

InternetArchiveBot is a powerful PHP, framework independent, OAuth bot designed primarily for use for WMF Wikis, per the request of the global communities, by Cyberpower678. It is a global bot that uses wiki-specific functions in an abstract class to run on different wikis with different rules. For maximum flexibility, it features on and off site configuration values that can be altered to suit the operator, and/or the wiki community. Its function is to address many aspects of linkrot. For large sites, it can be set to multi-thread with a specified number of workers to get the job done faster. Each worker analyzes its own page, and reports back to the master with the statistics afterwards.

What does it do?

IABot has a suite of functions it can do when it analyzes a page. Since the aim is to address link rot as completely as possible, analyzes links in many ways by,

1. Looking for URLs on the page rather than the DB. This allows the bot to grab how the url is being used, such as detecting if it's used in a cite template, a reference, or if it's a bare link. This allows the bot to intelligently handle sources formatted in various ways, almost like a human.
2. Checking the archives if a link already exists, and if it doesn't request archiving into the Wayback Machine.
3. Looking into the archives at the Wayback Machine to fetch a working copy of the page for a link that is dead, or using archives already being used for a URL on Wikipedia.
4. Checking if untagged dead links are dead or not. This has a false positive rate of 0.1%.
5. Automatically resolving templates that resolve as URLs in citation templates and working from there. The same also applies for templates as access dates.
6. Saving all that information to a DB, which allows for the use of interfaces that can make use of this information, and allows the bot to learn, and improve its services.
7. Convert existing archive URLs to their long form if enabled.
8. Fix improper usages of archive templates, or mis-formatted URLs.

Como funciona este trabalho

IABot's functions are in several different classes, based on the functions they do. Communication-related functions and wiki configuration values, are stored in the API class. DB related functions in the DB class, miscellaneous core functions in a static Core class, dead link checking functions in a CheckIfDead class, thread engine in Thread class, and the global and wiki-specific parsing functions in an abstract Parser class. While all but the last functions can run uniformly on all wikis, the Parser class requires a class extension due to its abstract nature. The class extensions contain the functions that allow the bot to operate properly on a given wiki, with its given rules. When the bot starts up, it will attempt to load the proper extension of the Parser class and initialize that as its parsing class.

Configuração

As of v2.0, the on wiki pages for configuring IABot are no longer used. The bot instead is configured with the IABot Management Interface. All global keywords are still used.

If you are running InternetArchiveBot yourself, you can configure it via the on wiki config page and by creating a new deadlink.config.local.inc.php file in the same directory. If someone else is running InternetArchiveBot and you just need to configure it for a particular wiki, you can set up a subpage of the bot's userpage called "Dead-links.js" and configure it there. For example, User:InternetArchiveBot/Dead-links.js. The configuration values are explained below:

• link_scan – Determines what to scan for when analyzing a page. Set to 0 to handle every external URL on the article. Set to 1 to only scan URLs that are inside reference tags.
• page_scan – Determines what pages to scan when doing it's run. Set to 0 to scan all of the main space. Set to 1 to only scan for pages that have dead link tags.
• dead_only – Determines what URLs it can touch and/or modify. Set to 0 to all the bot modify all links. Set to 1 to only allow the bot to modify URLs tagged as dead. Set to 2 allow the bot to modify all URLs tagged as dead and and all dead URLs that are not tagged.
• tag_override – Tells the bot to override its own judgement regarding URLs. If a human tags a URL as dead when the bot determines it alive, setting this to 1 will allow the tag to override the bot's judgement. Set to 0 to disable.
• archive_by_accessdate – Setting this to 1 will instruct the bot to provide archive snapshots as close to the URLs original access data as possible. Setting this to 0 will have the bot simply find the newest working archive. Exceptions to this are the archive snapshots already found and stored in the DB for already scanned URLs.
• touch_archive – This setting determines whether or not the bot is allowed to touch a URL that already has an archive snapshot associated with it. Setting this to 1 enables this feature. Setting this to 0 disables this feature. In the event of invalid archives being present or detectable mis-formatting of archive URLs, the bot will ignore this setting and touch those respective URLs.
• notify_on_talk – This setting instructs the bot to leave a message of what changes it made to a page on its respective talk page. When editing the main page, the talk page message is only left when new archives are added to URLs or existing archives are changed. When only leaving a talk page message without editing the main page, the message is left if a URL is detected to be dead, or archive snapshots were found for given URLs. Setting this to 1 enables this feature. Setting this to 0 disables it.
• notify_error_on_talk – This instructs the bot to leave messages about problematic sources not being archived on respective talk pages. Setting to 1 enables this feature.
• talk_message_header – Set the section header of the talk page message it leaves behind, when notify_on_talk is set to 1.

  See the #Magic Word Globals subsection for usable magic words.

• talk_message – The main body of the talk page message left when notify_on_talk is set to 1.

  See the #Magic Word Globals subsection for usable magic words.

• talk_message_header_talk_only – Set the section header of the talk page message it leaves behind when the bot doesn't edit the main article.

• archive#_tags – A collection of general archive tags to seek out, that supports the archiving services IABot uses. Automatically resolves the redirects, so redirects are not required. Format the template as you would on an article, without parameters. The "#" is a number. Multiple categories can be implemented to handle different unique archiving templates. This is dependent on how the bot is designed to handle these on a given wiki and is wiki specific.
• talk_only_tags – A collection of IABot tags to seek out, that signal the bot to only leave a talk page message. These tags overrides the active configuration.
• no_talk_tags – A collection of IABot tags to seek out, that signal the bot to not leave a talk page message. These tags overrides the active configuration.
• ignore_tags – A collection of bot specific tags to seek out. These tags instruct the bot to ignore the source the tag is attached to. Automatically resolves the redirects, so redirects are not required. Format the template as you would on an article, without parameters.

Phase 3 (in progress) – Deploy InternetArchiveBot on other wikis besides English Wikipedia (with community consent).

Management

Many aspects of InternetArchiveBot can be managed at https://iabot.toolforge.org/, including reporting false positives for dead links and directing the bot to fix a single page.
