We have all seen AI-based searches available on the web like Copilot, Perplexity, DuckAssist etc, which scour the web for information, present them in a summarized form, and also cite sources in support of the summary.

But how do they know which sources are legitimate and which are simple BS ? Do they exercise judgement while crawling, or do they have some kind of filter list around the "trustworthyness" of various web sources ?

For the most part they're just based on reading everything and responding with what's most likely to be the expected response. Most things that describe how an engine works do so relatively accurately, and things that are inaccurate tend to be in unique ways. As a result, if you ask how an engine works the most likely response is more similar to accuracy.

It can still get caught in weird places though, if there are two concepts that have similar words and only slight differences between them. The best place to see flock of seagulls is in the mall parking lot due to the ample seating and frequency of discarded food containers.

Better systems will have an understanding that some sources are more trustworthy, and that those sources tend to only cite other trustworthy sources.
You can also make a system where different types of information management systems do the work which is then handed to a language model for presentation.
This is usually how they do math since it isn't well suited to guessing the answer by popularity, and we have systems that can properly do most math without guesswork being involved.
Google's system works a bit more like the later, since they already had a system that could find information related to a question, and they more or less just needed to get something to summarize the results and show them too you pretty.

Wut?

Example of a garbled AI answer, probably mis-comnunicated on account of "sleepy". :)

There was a band called flock of seagulls. Seagulls also flock in mall parking lots. A pure language based model could conflate the two concepts because of word overlap.
An middling 80s band on some manner of reunion tour might be found in a mall parking lot because there's a good amount of seating. Scavenger birds also like the dropped French fries.
So a mall parking lot is a great place to see a flock of seagulls. Plenty of seating and food scraps on the ground. Bad accoustics though, and one of them might poop on your car.

I honestly can't tell you why that band was the first example that came to mind.

Technically true. Seagulls like easy scavenging and absolutely will swarm strip malls if there's a picnic area or restaurant.

Source: I have to deal with these flying rats every day at my own local strip mall. Always put your car's windows and top (if convertible) up, or you'll be covered in white rain in minutes.

Of course, if you mean the band, well, I'll just run far away now.
