  1. MediaWiki Bots: An Introduction for Beginners

MediaWiki bots are automated tools used to perform repetitive tasks on a wiki, relieving human editors of mundane work and contributing to the overall health and maintenance of the site. They are powerful assets for larger wikis, but can also be beneficial to smaller ones. This article will provide a comprehensive introduction to MediaWiki bots, covering their purpose, capabilities, setup, and common uses. We will focus on the tools and concepts relevant to MediaWiki version 1.40.

What are MediaWiki Bots?

At their core, MediaWiki bots are user accounts that are operated by software, rather than a human. They are programmed to execute specific tasks, often involving a large number of page edits. These edits, while numerous, are designed to be non-controversial and improve the wiki in a consistent and predictable manner. The software controlling the bot can be written in various programming languages such as Python, PHP, or Perl.

Think of it like this: manually fixing a typo on hundreds of pages would be incredibly tedious for a human. A bot can be programmed to find and correct that typo automatically, saving significant time and effort.

It's crucial to understand that bots are *not* meant to replace human editors. They are tools to *assist* human editors, freeing them up for more complex and nuanced tasks like content creation, dispute resolution, and policy enforcement. Incorrectly configured or poorly written bots can cause significant damage to a wiki, so careful planning and testing are essential.

Why Use a MediaWiki Bot?

There are numerous reasons why a wiki administrator might choose to implement a bot. Some of the key benefits include:

  • **Automation of Repetitive Tasks:** This is the primary benefit. Bots can handle tasks that are boring, time-consuming, and prone to human error.
  • **Improved Consistency:** Bots ensure that changes are applied consistently across the entire wiki, leading to a more uniform and professional appearance.
  • **Increased Efficiency:** Bots can perform tasks much faster than humans, significantly accelerating the maintenance and improvement process.
  • **Reduced Burden on Editors:** By automating routine tasks, bots free up human editors to focus on more important and creative work.
  • **Proactive Maintenance:** Bots can be scheduled to run automatically, providing continuous maintenance and identifying potential problems before they escalate.
  • **Scalability:** As a wiki grows, the workload increases. Bots provide a scalable solution for managing that workload.

Capabilities of MediaWiki Bots

MediaWiki bots can perform a wide range of tasks, including but not limited to:

  • **Fixing Common Typos:** Identifying and correcting frequently occurring spelling errors.
  • **Standardizing Formatting:** Ensuring consistent use of headings, lists, and other formatting elements. This aligns with principles of style guides.
  • **Adding Categories:** Automatically categorizing pages based on their content. Proper categorization is vital for information architecture.
  • **Updating Templates:** Refreshing data in templates, such as infoboxes or navigation boxes.
  • **Creating Stub Articles:** Generating basic articles for topics that are currently missing from the wiki.
  • **Removing Orphaned Pages:** Identifying and tagging or deleting pages that are not linked from anywhere else on the wiki.
  • **Adding Interwikis:** Linking articles to their equivalents on other wikis.
  • **Monitoring Recent Changes:** Identifying potentially problematic edits and flagging them for review. This is akin to risk management.
  • **Checking for Broken Links:** Identifying and reporting broken links within the wiki.
  • **Adding Missing Fair Use Templates:** Identifying and tagging images lacking appropriate fair use rationales.
  • **Archiving Talk Pages:** Moving old discussion threads from talk pages to archive pages.
  • **Implementing Semantic MediaWiki functionality:** Automated tagging and data extraction.
  • **Performing bulk edits based on regular expressions:** Powerful tool for complex find and replace operations. This is similar to applying a trading technical indicator to a dataset.

Setting Up a MediaWiki Bot

Setting up a bot involves several steps:

1. **Create a Bot Account:** Create a dedicated user account specifically for the bot. It's best practice to name the account something like "WikiBot" or "[WikiName]Bot". This account should *not* be used for any manual editing. 2. **Request Bot Status:** On most wikis, you'll need to request bot status for the account. This typically involves submitting a request to the administrators or a dedicated bot requests page. The request should clearly outline the bot's intended purpose and capabilities. 3. **Choose a Bot Framework:** Select a software framework for controlling the bot. Popular options include: 

   *   **PyWikiBot:** A Python-based framework that provides a wide range of tools for interacting with the MediaWiki API. [1]
   *   **AutoWikiBrowser (AWB):** A GUI-based tool written in C# that allows users to perform bulk edits with a visual interface. [2]
   *   **Wikibot Framework:** Another Python-based option. [3]

4. **Configure the Bot:** Configure the bot with the necessary credentials (username, password, API endpoint) and settings. This usually involves editing a configuration file or setting environment variables. 5. **Write the Bot Script:** Write the script that defines the bot's behavior. This script will use the MediaWiki API to interact with the wiki and perform the desired tasks. Understanding the MediaWiki API is crucial here. 6. **Test the Bot:** Thoroughly test the bot on a test wiki or a small subset of the live wiki before deploying it to the entire site. Start with small, non-controversial edits and gradually increase the complexity. A/B testing different bot configurations can optimize performance, similar to backtesting a trading strategy. 7. **Deploy the Bot:** Once you're confident that the bot is working correctly, you can deploy it to the live wiki. 8. **Monitor the Bot:** Regularly monitor the bot's activity and logs to ensure that it's functioning as expected and not causing any problems. Analyzing the bot's logs is like performing data analysis on trading results.

Common Bot Tasks in Detail

Let's delve deeper into a few common bot tasks:

  • **Fixing Typos:** Bots can use dictionaries and regular expressions to identify and correct common spelling errors. For example, a bot could be programmed to replace "teh" with "the" throughout the wiki. This relies on pattern recognition, similar to identifying chart patterns in financial markets.
  • **Adding Categories:** Bots can analyze the content of a page and automatically add relevant categories. This requires a good understanding of the wiki's categorization scheme. Algorithms can be used to determine category relevance based on keywords and phrases, much like a sentiment analysis tool assesses market mood.
  • **Updating Templates:** Bots can be used to update data in templates, such as population figures in infoboxes. This requires the bot to access external data sources or query the wiki's database. This is similar to a trading bot utilizing a real-time market data feed.
  • **Removing Orphaned Pages:** Bots can identify pages that are not linked from anywhere else on the wiki. These pages are often abandoned or irrelevant and can be tagged for deletion. This is a form of wiki housekeeping.
  • **Archiving Talk Pages:** Bots can automatically move old discussion threads from talk pages to archive pages. This helps to keep talk pages organized and manageable. A well-maintained talk page reflects good communication skills.

Important Considerations and Best Practices

  • **Respect the Wiki's Policies:** Always adhere to the wiki's policies and guidelines when developing and deploying a bot.
  • **Avoid Disruptive Edits:** Bots should only perform non-controversial edits that are unlikely to be reverted.
  • **Rate Limiting:** Implement rate limiting to prevent the bot from overloading the wiki's servers. The MediaWiki API has rate limits that must be respected. This is analogous to risk management in trading.
  • **Error Handling:** Implement robust error handling to prevent the bot from crashing or causing unexpected behavior.
  • **Logging:** Keep detailed logs of the bot's activity for debugging and monitoring purposes.
  • **Regular Updates:** Keep the bot's software and scripts up to date to ensure compatibility and security.
  • **Community Consultation:** Consult with the wiki community before deploying a bot, especially if it's going to perform complex or potentially disruptive tasks. Open communication is vital for building trust.
  • **User Rights:** Ensure the bot account has only the necessary user rights to perform its tasks. Avoid granting it administrator privileges unless absolutely necessary.
  • **Understand the API:** A deep understanding of the MediaWiki API is essential for developing effective bots.
  • **Consider the impact on server load:** Large-scale bot operations can significantly increase server load. Schedule tasks during off-peak hours if possible. This is similar to considering market liquidity when executing large trades.

Advanced Bot Techniques

  • **Using Regular Expressions:** Regular expressions are powerful tools for pattern matching and text manipulation. They can be used to perform complex find and replace operations. This is akin to using advanced technical analysis tools.
  • **Accessing External Data Sources:** Bots can be programmed to access external data sources, such as databases or APIs, to enrich the wiki's content.
  • **Machine Learning:** More advanced bots can incorporate machine learning techniques to automate tasks that require more intelligence, such as content categorization or spam detection.
  • **Parallel Processing:** Using parallel processing can significantly speed up the bot's execution time.
