Here is the how TwitterJobSearch describe their service:

Until now, search engines for social media sites merely looked for words.
We’re looking at context.

We use semantic tools to look at what was said.
We then look at what they’ve said before.
We then look at who was saying it.

If we do this right, we can figure out why they’re saying anything at all.
