IRC Channel

ClueBot NG's development and discussion about internals takes place almost entirely on its IRC channel. The IRC channel can be accessed on channel #cluebotng. Please join if you have any detailed questions about the internals or would like to speak real-time with the developers.

Bots in #cluebotng that may be useful are:

  • CBNG-RC - RCBot for the report interface. Relays new reports, report comments and changes in status (such as reports getting picked up by the review interface).
  • ClueBot_NG - Live bot, mostly does nothing but relays some edit info such as pages listed on User:Cobi/CBAutoedit.js

Dataset Review Interface

For the bot to be effective, the dataset needs to be expanded. Our current dataset has some degree of bias, as well as some inaccuracies. We need volunteers to help review edits and classify them as either vandalism or constructive. We hope to eventually completely replace our current dataset with a random sampling of edits, reviewed and classified by volunteers. More thorough instructions on how to use the interface, and the interface itself, are at the dataset review interface.

Extended statistics on contributors, including edit review counts and accuracy, are available here.

For those that help with and contribute to the review interface, a user box is available for you:

US Air Force 021105-O-9999G-001 Spirit in the blue sky.jpg This user reviews dataset edits for ClueBot NG to help automatically mass revert vandalism on Wikipedia.

Use it with: {{User:ClueBot NG/Review User Box}}


As ClueBot-NG requires a dataset to function, the dataset can also be used to give fairly accurate statistics on its accuracy and operation. Different parts of the dataset are used for training and trialing, so these statistics are not biased.

The exact statistics change and improve frequently as we update the bot. Currently:

  • Selecting a threshold to optimize total accuracy, the bot correctly classifies over 90% of edits.
  • Selecting a threshold to hold false positives at a maximal rate of 0.1% (current setting), the bot catches approximately 40% of all vandalism.
  • Selecting a false positive rate of 0.25% (old setting), the bot catches approximately 55% of all vandalism.

Currently, the trial dataset used to generate these statistics is a random sampling of edits, each reviewed by at least two humans, so statistics are accurate.

Note: These statistics are calculated before post-processing filters. Post-processing filters primarily reduce false positive rate (ie, the actual number of false positives will be less than stated here), but can also slightly reduce catch rate.

Frequently Asked Questions

See the FAQ.

Vandalism Detection Algorithm

ClueBot-NG uses a completely different method for classifying vandalism than all previous anti-vandal bots, including the original ClueBot. Previous anti-vandal bots have used a list of simple heuristics and blacklisted words to determine if an edit is vandalism. If a certain number of heuristics matched, the edit was classified as vandalism. This method results in quite a few false positives, because many of the heuristics have legitimate uses in some contexts, and only about a 5% to 10% vandalism catch rate, because most vandalism cannot be detected by these simple heuristics.

ClueBot-NG uses a combination of different detection methods which use machine learning at their core. These are described below.

Machine Learning Basics

Instead of a predefined list of rules that a human generates, ClueBot-NG learns what is considered vandalism automatically by examining a large list of edits which are preclassified as either constructive or vandalism. Its concept of what is considered vandalism is learned from human vandal-fighters. This list of edits is called a corpus or dataset. The accuracy of the bot largely depends on the size and quality of the dataset. If the dataset is small, contains inaccurately classified edits, or does not contain a random sampling of edits, the bot's performance is severely hampered. The best thing you and other Wikipedians can do to help the bot is to improve the dataset. If you're interested in helping out, please see the Dataset Review Interface section.

Bayesian Classifiers

A few different Bayesian classifiers are used in ClueBot-NG. The most basic one works in units of words. Essentially, for each word, the number of constructive edits that add the word, and the number of vandalism edits that add the word, are counted. This is used to form a vandalism-probability for each added word in an edit. The probabilities are combined in such a way that not only words common in vandalism are used, but also words that are uncommon in vandalism can reduce the score.

This differs from a simple list of blacklisted words in that word weights are exactly determined to be optimal, and there's also a large "whitelist" of words, also with optimal weights, that contributes.

Currently, there's also a separate Bayesian classifier that works in units of 2-word phrases. We may add even more Bayesian classifiers in the future that work in different units of words, or words in different contexts.

Scores from the Bayesian classifiers alone are not used. Instead, they're fed into the neural network as simple inputs. This allows the neural network to reduce false positives due to simple blacklisted words, and to catch vandalism that adds unknown words.

Artificial Neural Network

The main component of the ClueBot-NG vandalism detection algorithm is the neural network. An artificial neural network is a machine learning technique that can recognize patterns in a set of input data that are more complex than simply determining weights. The input to the ANN used in ClueBot-NG is comprised of a number of different statistics calculated from the edit, which include, among many other things, the results from the Bayesian classifiers. Each statistic has to be scaled to a number between zero and one before being input to the neural network.

The output of the neural network is used as the main vandalism score for ClueBot-NG. As with other machine-learning techniques, the score's accuracy depends on the training dataset size and accuracy.

Threshold Calculation

The ANN generates a vandalism score between 0 and 1, where 1 is 100% sure vandalism. To classify some edits as vandalism, and some as constructive, a threshold must be applied to the score. Scores above the threshold are classified as vandalism, and scores below the threshold are classified as constructive.

The threshold is not randomly chosen by a human, but is instead calculated to match a given false positive rate. When doing actual vandalism detection, it's important to minimize false positives to a very low level. A human selects a false positive rate, which is the percentage of constructive edits incorrectly classified as vandalism. A threshold is calculated to have a false positive rate at or below this percentage, while maximizing catch rate. False positive rate is set by a human, and the bot stays at or below that false positive rate, while catching as much vandalism as possible. The false positive rate is not fixed, but is adjustable.

To make sure the threshold and statistics are accurate and do not give inaccurate statistics or a higher false positive rate than expected, the portion of the dataset used for threshold calculations is kept separate from the training set, and is not used for training. Also, only the most accurate parts of the dataset (currently, the ones that are human-reviewed from the review interface) are used for this calculation. This ensures that all statistics given here are accurate, and that false positives will not exceed the given rate.

Post-Processing Filters

After the core makes its primary vandalism determination, the data is given to the Wikipedia interface. The Wikipedia interface contains some simple logic designed to reduce false positives. Although it also reduces vandalism catch rate a small amount, it also reduces false positive rate, and some of these are mandated by Wikipedia policy.

The first two of these rarely reduce catch rate, but both prevent a fair number of false positives. Note: The false positive rate (and catch rate) are calculated in the core, before post-processing filters. This means that actual false positive rate will be less than stated false positive, often by a significant factor.

  • User Whitelist - If an edit made by a user that is in a whitelist is classified as vandalism, the edit is not reverted.
  • Edit Count - If a user has more than a threshold number of edits, and fewer than a threshold percentage of warnings, the edit is not reverted.
  • 1RR - The same user/page combination is not reverted more than once per day, unless the page is on the angry revert list.

Development News/Status

Core Engine

  • Current version is working well.
  • Currently writing a dedicated wiki markup parser for more accurate markup-context-specific metrics. (No existing alternative parsers are complete or fast enough)

Dataset Review Interface

  • Code to import edits into database is finished.
  • Currently changing logic that determines the end result for an edit.

Dataset Status

  • We found that the Python dataset downloader we used to generate the training dataset does not generate data that is identical to the live downloader. It's possible that this is greatly reducing the effectiveness of the live bot. We're working on writing shared code for live downloading and dataset generation so we can regenerate the dataset.
  • This has been fixed and the bot retrained. It's now working much better.
  • Currently getting more data from the review interface.


  • C / C++ — The core is written in C/C++ from scratch.
  • PHP — The bot shell (Wikipedia interface) is written in PHP, and shares some code with the original ClueBot.
  • Java — The dataset review interface is written in Java using the Google App framework.
  • Bash — A few scripts to make it easier to train and maintain the bot are Bash scripts.
  • Python — Some of the original dataset management and downloader tools were written in Python.

Source Code

The source code for the bot is public, and available on request. Please join the IRC channel and ask the devs for access. If you would like to run the bot for yourself on your own wiki, you should discuss with the devs all the factors involved in making it work properly. You should also be aware that it will only run on a Linux/UNIX system, and the source code can be rather difficult to compile (many dependencies) unless you're experienced with Linux/UNIX systems.

ClueBot-NG RC Feeds

ClueBot-NG provides two IRC-based feeds of its data, primary intended for use by other automated tools. Both feeds are on the server The feeds are:

  • Vandalism Feed on #wikipedia-van — This is a feed of all edits that ClueBot-NG calculates to be above vandalism threshold. Not all of these edits are reverted due to post-processing filters. The edit's score, whether it was or was not reverted, and the reason for the revert/not-revert, is given in the feed. Format is \x0315[[\x0307 article title \x0315]] by "\x0303 edit user \x0315" (\x0312 diff url \x0315) \x0306 Revert time (in seconds) \x0315 ("\x0304 Reverted or Not Reverted \x0315) (\x0313 Reason \x0315) (\x0302 Process time (in seconds) \x0315s).
  • Complete RC Feed on #cluebotng-spam — This is essentially a copy of the Wikipedia RC feed, but with ClueBot-NG's analysis data added. It includes everything the Wikipedia RC feed does, with the addition of the ClueBot-NG score and whether it was reverted or not. Format is edit line \003 # score # reason # Reverted or Not reverted

Note that edits in the feed may not necessarily be in precise order, because ClueBot-NG processes them in parallel. But non-reverted edits are usually processed in under a second. Reverted edits can sometimes take up to 10 seconds or more to process due to API lag on reverting.

Information About False Positives

ClueBot-NG is not a person, it is an automatic robot that tries to detect vandalism and keep Wikipedia clean. A false positive is when an edit that is not vandalism is incorrectly classified as vandalism.

The bot is not biased against you, your edit, or your viewpoint (unless your edit is vandalism). False positives are rare, but do occur. By handling false positives well without getting upset, you are helping this bot catch over half of all vandalism on Wikipedia and keep the wiki clean for all of us.

False positives with ClueBot-NG are (essentially) inevitable. For it to be effective at catching a great deal of vandalism, a few constructive (or at least, well-intentioned) edits are caught. There are very few false positives, but they do happen. If one of your edits is incorrectly identified as vandalism, simply redo your edit, remove the warning from your talk page, and if you wish, report the false positive. ClueBot-NG is not (yet) sentient - it is an automated robot, and if it incorrectly reverts your edit, it does not mean that your edit is bad, or even substandard - it's just a random error in the bot's classification, just like email spam filters sometimes incorrectly classify messages as spam.

The reason false positives are necessary is due to how the bot works. It uses a complex internal algorithm called an Artificial Neural Network that generates a probability that a given edit is vandalism. The probability is usually pretty close, but can sometimes be significantly different from what it should be. Whether or not an edit is classified as vandalism is determined by applying a threshold to this probability. The higher the threshold, the fewer false positives, but also less vandalism is caught. A threshold is selected by assuming a fixed false positive rate (percentage of constructive edits incorrectly classified as vandalism) and optimizing the amount of vandalism caught based on that. This means that there will always be some false positives, and it will always be at around the same percentage of constructive edits. The current setting of the false positive rate is listed in Statistics above.

When false positives occur, they may not be poor quality edits, and there may not even be an apparent reason. If you report the false positive, the bot maintainers will examine it, try to determine why the error occurred, and if possible, improve the bot's accuracy for future similar edits. While it will not prevent false positives, it may help to reduce the number of good-quality edits that are false positives. Also, if the bot's accuracy improves so much that the false positive rate can be reduced without a significant drop in vandalism catch rate, we may be able to reduce the overall number of false positives.

If you want to help significantly improve the bot's accuracy, you can make a difference by contributing to the review interface. This should help us more accurately determine a threshold, catch more vandalism, and eventually, reduce false positives.

I don't think were going to have to wait that long. :D --Ixfd64 (talk) 07:06, 4 November 2010 (UTC)
Of course, we could have a >99.9% detection rate by making the bot revert every edit from a non-whitelisted user, but the false positive rate would be a tad high, wouldn't it? --Ixfd64 (talk) 07:07, 4 November 2010 (UTC)
The false positive rate is configurable — vandalism catch rate depends on it. Current false positive rate is 0.25%, which seems reasonable. It may end up being lowered, but is unlikely to be raised. At this rate, we are currently catching about 60% of vandalism. 99.9% isn't a realistic goal, because some borderline edits really should have a human decide. But maybe we can get close. Crispy1989 (talk) 07:20, 4 November 2010 (UTC)

I noticed this bot pop up on my watchlist, as I understand it, it seems likley that when completed it will be able to catch and revert upto 70% of the vandalism on wikipedia within 0.02 seconds with a 0.5% false positive rate? <---- That's a very exciting prospect, great work! Ajbpearce (talk) 21:31, 5 November 2010 (UTC)

Well, it can already catch 70% of vandalism, with a 0.5% false positive rate, and the core operates in 0.02 seconds. However, the false positive rate was lowered to 0.25% (at which it catches around 60% of vandalism) and may be lowered still. Also, 0.02 seconds is how long it takes the core to classify an edit as vandalism. The interface to Wikipedia takes most of the time, and can add up to several seconds to this. Crispy1989 (talk) 00:53, 6 November 2010 (UTC)
Thank you for this bot. It seems quite more aggressive than previous bots, and that's a great thing. With the amount of vandalism we see, I much rather have the occasional false positive than scale back the triggers. --CutOffTies (talk) 16:10, 18 November 2010 (UTC)

When I realized how much I relied on wikipedia I made a pledge to hand fix at least five acts of vandalism a day (That includes fact checking of minor date changes and similar issues). Problem is, you catch at least 3/5 of those right when I click on them! I click on the history, see obvious vandalism, go to edits... when BOOM! It's already gone, along with a warning for the user.

I for one am really glad to see you back. I'm just a regular Wikipedian, but when I heard Cluebot NG went down I started freaking out and ended up watchlisting a bunch of pages, just so I could defend them. I was very concerned about the vandalism that was piling up on Wikipedia, and really hoping that your server issue would be addressed swiftly. Fortunately, the bot's back up and running now, so everything seems much better now. I'm sorry to hear about the dataset issues, but I've looked at its contributions and the vast majority of its reverts are vandalism, which pleases me very much. Seriously, well done on the bot programming, it truly is a remarkable accomplishment. If you ever have trouble with finances again, do speak up and I'm sure we the appreciative community will see what we can do. :D Impressed and pleased, Jessemv (talk) 07:40, 11 December 2011 (UTC)

It's sad how little praise there is here. Anyway I was amazed that Cluebot detected this as vandalism... it has no junk characters, profanity or hate speech, it's a normally-written insertion of a tired but obscure conspiracy theory. Pretty cool that a bot could detect that as vandalism. Nice work. --Runame (talk) 15:07, 10 January 2012 (UTC)

Darn you Clue Bot! I was so exited that I caught a vandal in the act, and I was just about to revert it, when it disappeared. How can we possibly keep up with you? (talk) 19:08, 8 February 2012 (UTC)

Hi ClueBot! Just wanted to say thank you for finding the false positive in the James B. Harkin article I was working on. Looks like a friend was playing around with my class project when he found out about it. Didn't realize it even occurred since you found it so quickly. Very amazing to see how quick wikipedia can catch things like this :) --Allisontheresa (talk) 22:04, 9 April 2012 (UTC)

You are so extremely and utterly awesome. When i grow up i wanna be just like you. I love you. Will you marry me? Please? U r my idol. u r hotter than jessica simpson — Preceding unsigned comment added by (talk) 02:03, 11 April 2012 (UTC)

Thanks to ClueBot creators and maintainers for doing a great job. It is appreciated. One of the best things about its counter-vandalism work is that, in many cases, the vandals don't even have time to gloat at the results of their actions before they are reverted. One almost feels sorry for them... Maias (talk) 00:29, 2 May 2012 (UTC)

Do 'bots possess self-awareness and a sense of humor in comments or was this comment: "(reverting possible vandalism by to version by Helpful Pixie Bot)" at this edit just coincidence? Either way thanx, it gave me a good laugh on a dismal day. --Naaman Brown (talk) 22:12, 28 August 2012 (UTC)

Thank you for the revert that you recently conducted to the Flip tricks article, as the vandalism was blatantly racist and has no place on this website.--Soulparadox (talk) 03:23, 13 December 2012 (UTC)

ClueBot, I think you are one of the nicest robots I have ever met, not that I know that many or anything... If you guys ever ponder taking over and / or getting rid of all the pesky humans, while I am wholly obligated against collaboration contrary to the interests of the human race, I hope you would take the chance to get to know me first before giving up on my brethren, and through me you might learn that we are not truly so bad, and our peoples can surely find peace and friendship despite our differences, and learn to better explore and shape our world, together, for the benefit of time. For peace, love, and truth! --Elgaroo (talk) 06:43, 2 February 2013 (UTC)

Please stop reverting all the vandalism, ClueBot. All those reverts are impressing me, and if you continue to revert vandalism, I might give you a Barnstar! Epicgenius (talk) 20:59, 4 April 2013 (UTC)

But keep up the great work at reverting vandals almost instantly! StevenD99 Talk | Stalk 04:18, 14 September 2013 (UTC)

I've taken ClubBot for granted for years and was so relived to have 80% of the vandalism caught immediately and reverted. By the time I crawled up the watchlist, I could attend to actual content. Having ClueBot down for a few days earlier this month was truly a reminder of how much we depend on you guys. Thanks. Student7 (talk) 19:59, 20 October 2013 (UTC)

I find that a lot of the bots on Wikipedia do annoying things, like making unnecessary edits ("imdb" to "IMdB", for instance, or "commonscat" to "Commons category"), but I'm very thankful that ClueBot is around. It is, by far, the most useful bot we have, and I'm grateful for it every time I see vandalism that it has fixed. Everyone involved is to be congratulated for a really great job, and for the service you all have provided to the community. Beyond My Ken (talk) 02:00, 30 October 2013 (UTC)

It's funny. 9 times out of 10 I find a vandal on the edit filter, ClueBot has beaten me to the punch no matter how innocuous or random the edit seems to be. To the programmer(s), great job and keep up the awesome work! I hope you continue to beat me to the punch and help keep Wikipedia free of vandalism! Jns4eva (talk) 05:57, 4 November 2013 (UTC)

Information icon Please refrain from reverting too much vandalism on Wikipedia. While we certainly appreciate the help, rollbackers, recent changes patrollers, and users who want to help out are quickly losing their jobs. If you revert any more vandalism, you may be spammed repeatedly with barnstars and you will be showered with roses and confetti. Lolz, keep up the good work! K6ka (talk) 17:40, 6 November 2013 (UTC)

I was looking in the history of the article on Kant, and I discovered that earlier today a piece of very stupid and counter-productive (but admittedly hilarious; I would never encourage it, but seeing as it was already reverted I was able to get a good giggle from it) vandalism was reverted in the very same minute it was added! I was confused and impressed. I don't understand how this bot works, but—for its good work—I definitely do thank both it and its human overlords (who I presume exist; please, God, don't let this bot be sentient! Its power would be too great!) BreakfastJr (talk) 10:45, 29 January 2014 (UTC)

Well, I've always been impressed by ClueBot NG's advanced artificial neural network, and its large database of edits, but I am still mindblown on how it could catch this. You're a very underestimated bot. Underestimated and neglected by the world. It seems only the people who edit Wikipedia know about you. The readers don't know about you. The teachers don't know about you. And if they did, they'd be more comfortable reading Wikipedia and knowing that a lot of work and time and effort has been put into building the articles, and a bot plus an army of rollbackers that number in the thousands to keep it clean from vandalism.

And yes, if you haven't seen those warnings I gave you - you should really stop beating me to reverts all the time. K6ka (talk | contribs) 02:49, 13 February 2014 (UTC)

Hello, I just want to let you know THAT CLUEBOT IS SO FAST THAT IT IS ANNOYING ME BECAUSE IT REVERTS VANDALISM BEFORE I FIND IT XD. No hard feelings. Nice job keeping Wikipedia good and clean, I have seen everything. Happy_Attack_Dog "The Ultimate Wikipedia Guard Dog" (talk) 15:00, 28 February 2014 (UTC)

this is ridiculous. I cannot believe that anyone can program an algorithm to find such teensy-weensy little edits of vandalism buried in there. nope, nope, nope. i'm wondering if those were just a test... then again, come to think about it...even if they were a test...obviously ClueBot ACED IT. :p amazing. you guys rock!!!

Stop hand.svgSTOP. This is a message informing you that you have breached the limit of edits you are authorized to do as of May 28, 2014.
