A system like this would certainly be very hard to create because of the human element.
Humans are far smarter than machines.
Say, the machine succeeded and a terrorist cell was brought down.
The other cells will change their tactics and beat the system hands down.
e.g

they'll communicate codedly, such that their communication will go under the snoopers noses undetected.
imagine this kind of conversation:
A : Man, i saw a fine shoe i like but it was very expensive?
B : How much?
A : $1000
B: why didnt you borrow money to buy it
A : The bank wouldnt lend me?
B: ugh, banks are no good, next time, go to a lender
A : dyu know any?
B : Yes,
A : where?
B: i know one at 18 broad street, and another at 20 minks street
A : okay, i'll check them out
B: ok, tell me how the next bargain goes.

How would you suspect a terrorist activity from such a conversation?!
But this could be terrorist conversation transpiring codedly!

for those still confused here's a lil of the top of my head encoding.

"i saw a fine <whatever> " - I've found a suitable target but
"it was very expensive " - the security detail is too much
"why didnt you go to banks " - will the usual avenue not work?
"bank's wouldnt lend me " - no, brute force or usual tactic will fail
"go to the dealers " - meet master strategists, higher ups, to pull strings.
"18 broad street, mink street " - useless detail that doesnt mean anything , meant
to confuse any eaves dropper.
the other person knows who the "dealers" are.

for computers to be bought into the equation, we have to assume that relevant data is already available and need to be processed into information. how these data are gotten is not our businesses but that of the law enforcement agents

larisoft:
uhmmm...let me try

I d have a listener triggered every time a new batch of data is received,make objects of these data and pass the objects, each with fields like type, content, sender, receiver etc, as parameters to a 'process' method.


in this method, using several objects, algorithms and libs, I ll search for occurrences of terrorist-like words in the data like " bombs, explode , target. Match pictures to faces of known terrorists. match recordings to vocals of radical sentences. and grade each object based on the frequency by which these words/pictures/audio occur before inserting into db and notifying listeners that new information is ready.


at the front end, an Ajax call simply monitors one of these listeners every 5 or so seconds (could be a txt file containing the no of updates made to db so far) once it detects a change, it queries the.database and refreshes the screen with new results of the highest threats.

pretty much all technologies can be used but java and c# could be favored since this system will require a lot of processing power that ll be missed in interpreted languages...

ngwa, correction, sir.

your Algorithm would be too slow because no filter to monitor phone calls , text of millions and Internet activities all at once . One hour may crash the system . Your super computer processor may take days to process querys , it will load for days with no hit .

This is a very big project that requires database centres like Google and Facebook . One terabyte per minute is not an easy setup .
