What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 127 Stack Exchange communities.

When one asks a simple question on this forum, the site doesn't allow the user to post it, as it detects that the question is too easy as per the Q&A and user standards.

My question is, what algorithm does Stack Exchange employ here that assesses the difficulty level of the question asked?

Being a computer engineer I am not able to even get a hint of that. Do they search for key words like "what", "simple thing" etc.?

No algorithm, just hard-working people. And your question is better suited to Meta Stack Overflow. –  David Gorsline May 5 '12 at 23:43

We do not have the feature you describe. There is nothing that detects questions as "too easy". In fact, there is nothing wrong with asking "easy" questions. What's easy to one person may not be easy for another. That's the whole premise behind a collaboratively-edited Q&A site.

There is, however, something wrong with asking questions that don't make any sense, that more closely resemble "assignments" rather than questions, that show no effort of research effort on the part of the asker, that cannot be reasonably answered, and that are not correctly formatted.

To this end, we do have a quality filter in place. You can read more about it, and how to compose your question to avoid tripping it, in the answer to this question.

Also, please see the FAQ for more information on the types of questions you can and cannot ask.

If you're still having trouble asking your question on Stack Overflow, please edit your question here and include the full text of the question you're attempting to post. We will be more than happy to tell you what's wrong with it and give you some suggestions on how to improve it.

how could you detect a question, if it make no sense using some keyword filtering? –  user65130 May 24 '12 at 10:10
    
@user You can't. We don't do that either. That's what close votes are for. –  Cody Gray May 24 '12 at 10:10
    
sometimes I cant post a question, I only get a message that this question does not meet the standards. –  user65130 May 24 '12 at 10:14
    
Ah, there is a secret "quality" detection algorithm. Updated answer to reflect that. Top secret how it works, though. We don't want people working around it easily. We want people to actually fix their questions. –  Cody Gray May 24 '12 at 10:14

This is misleading!

Instead of:

Oops! Your question couldn't be submitted because:

  • It does not meet our quality standards.

it should say:

Oops! Your question couldn't be submitted because:

  • It does not fit to our secret quality filter algorithm, we have created against dummies. Extend your answer according to Q&A in a hope that next time you will pass.

Except that's not what it means. The quality filter wasn't created to keep out "dummies", it was created to keep out bad questions. Since you want to press the issue, I'll give you a hint: it is weighted heavily against people who do not use proper grammar. If you fail to capitalize the letter I and/or do not use any punctuation, you will probably be blocked from submitting your question. It's a standard quality control feature, not intended to filter the subject matter of a question, but rather the presentation. –  Cody Gray May 24 '12 at 10:29

There isn't such thing as a dummy filter, otherwise this answer wouldn't have made it through... –  Yannis May 24 '12 at 10:35
