It depends on the context.

These grammars that we've been introducing describe something new context free languages.

You might think, Boy, is there a context expensive grammar out there? What's the opposite of free?

That's an excellent question.

These days I think your time, the human's time, is more important than the computers.

But that's an example of an application that also uses this sort of linguistic analysis perhaps a little less related to context free grammars but still in the same vein.

They may get a little bit bigger, but it will totally work.

I am just gonna pause for a moment to let you think about that.

Another common story or storyline is the claim that we have to get tough .

This is always true because we have our Pac Man diagram here, and also because you can take any regular language and represent it with a context free grammar.

But is there anything beyond that?

We'll talk about it in a lot of different contexts.

... the misspelled word shown in context...

But if right above it I've written X 0, then we'd get a different answer.

Units 3 and 4 were relatively abstract to some degree, intentionally so.

A context free grammar can capture the language a N and b N, where N is the same.

Finite State Machines, adding a lexer that follows them automatically,

The meaning of words can change according to their context.

It handles LL. It handles LR. It handles LALR.

The brain is recording all information and driving all change in temporal context.

like HTML or SQL, the language of database queries.

The set of languages that can be described by re write rules or grammers like this are called context free languages.

It relates grammars to parsing, which is one of the concepts in this class.

All of that is going to matter for figuring out the true interpretations of programs.

It can really be a contortion that distorts meaning to try to get C to fit into one of these other tools.

So in lecture, we spent a lot of time learning about context free grammars and languages.

Actually, they're both just concise notations for specifying possibly infinite sets of strings.

likewise, a very distinctive notion of the family, social relationships like guanxi,

That line above it is the context.

What we want to determine is how we can connect these two.

These are just the ESPN SportsCenter version of the game.

Sometimes this statement is true, and sometimes it's not.

Same as ever. This taricardia is killing me.

This New York means the same to me as it does to everyone else.

This branch of the family is all about representation.

Here I've written down four claims.

These are both infinite, infinite grammars.

In theory, you could compose it over here as well.

And understand its interactions with the entire Earth.

All right. Now that you've gone to the hard work of defining all of those procedures,

In most interpreters, this is a problem.

And also do fine and do reasonable things even if your data is not linearly separable.

Right it's gonna have to go away from the heart. So that's the aorta. The aorta actually has the little arch like that.

The concept conjures of thoughts of our species, our planet and our civilization.

Build the system so that anybody can contribute at any amount.
