I use quite a few of 'J', 'L' and 'F', but generally I doubt theres enough
usage of alphabetic characters to be able to detect ASCII art from the presence
of letters rather than the absence.
You could link it with a spell checker - if it cant find any words it recognises
in large amounts of ASCII then its probably not writing.

Hello. I am writing a program to detect ASCII art in email messages. I am currently designing the heuristics, or to put it another way, I'm trying to work out how you can identify the presence of ASCII art. I thought I'd write and ask you folks who do lots of it what you think the determining features are. My observations so far: There's lots of spaces, often at the start of a line. Spaces are used differently to those in text. There are few tab characters used. Many non-alphanumeric characters are used. If you can add any more features, such as the alphabetic characters that you use a lot of, then I'd be most grateful. (The program will be in Perl, but any code or pseudocode will also be warmly received.) Many thanks, Ian.

None, if you are precise. Otherwise it wouldn't be ASCII Art :-) > Many non-alphanumeric characters are used. Well. It don't think that you can find a script that catches most of the arts. Why? Some are very small, some are larger. Some even use just words you find in a dictionary, or even consist of plain HTML (like VK's NO HTML ;)). It fully depends on the artist what characters he like to use. There are even arts around that just use 8, d, b P q and so on - and nothing that isn't alphanumeric. So I simply think it's hard to judge. Just stick to this simple rule: Use always an monospaced font - you don't know what you'd miss otherwise ;) What for do you want to do such a thing? > If you can add any more features, such as the alphabetic characters > that you use a lot of, then I'd be most grateful. As mentioned above - that depends fully on the artist. Some use J and F for lines, others are only /, \ and so forth. I wish you _much_ luck with you - you will need it desperately!

I would bet that you could get fairly solid results if you searched for
occurances of /, |, and \ as your primary hooks. Toss in - and _, maybe +
and some others (. and , and ' and = and others) if you like, or as a
lower-weighted factor for your heuristic, but in terms of raw efficiency,
the pipe and slashes are probably more omnipresent in ASCII art and
lacking in non-ART posts than any other characters. The first 80% or so
of the search is the easist part. :)

Yes, that too. :-) > It sure wouldn't survive your ascii-checker, Veronika =) No, but the point was that it wouldn't survive Henry Segerman's suggestion that one use a spell checker to identify what's _ascii art_. That *might* work, for *some* pictures, *if* everybody wrote in English (assuming that it would be an English spell checker).

A high proportion of spaces and punctuation would be indicative of possible ascii-art.

But it's hexB4. It's not that big problem, actually. And the second thing is that you used the tab character at the last line. You won't see it in the orgiginal post if your tabstops are setup to 8 chars - but if it's quoted, and maybe someone else have tabstops set to something else that can break the picture up.

You could include very common but multiple letter words like 'the' in as
many languages as you want. I'm guessing that in the end the decision as
to wether something is ascii art or not is going to come down to adding up
a number of factors with weightings and comparing against a threshold value.
So anything we can say about what ascii art usually is is good.

Heh. Touche'. Then again, regexps in Perl are a sort of art themselves.

After reading some of the suggestions in this thread, I've had a go at this and have had a fair amount of success detecting which posts to this group contain ascii-art, and in avoiding false positives with other types of text such as source code. I've only used 7 rules so far, but I've tried to make it easy to add new ones, and to adjust the weighting values.
