Author | Topic: Data, Information, and all that.... | |||||||||||||||||||||||
Peter Member (Idle past 1479 days) Posts: 2161 From: Cambridgeshire, UK. Joined: |
I came across this recently:
"Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe." The research is actually from a doctoral thesis by Graham Rowinsonat Nottingham University (1976), but it made me think. Several very different orderings of the same data can provideexactly the same information. Not because of anything in the data, but because our mindsinterpret the data into something we recognise. I think this shows that data and information are separate(not entirely independent, but not the same thing). This means that ANY change in data COULD be an increase information regardless if whether the data increases or decreases and maynot change at all. Not sure whether that is a useful thought or not now ... stillthat's never stopped me before

(not entirely independent, but not the same thing). This means that ANY change in data COULD be an increase information regardless if whether the data increases or decreases and maynot change at all. Not sure whether that is a useful thought or not now ... stillthat's never stopped me before. Maybe you should begin stopping now? The reason for this apparent "identity" between data and information is that you've forgotten about the presence of the bridging feature - the software! It is the human mind - with its vast processing capabilities including memory, pattern recognition, and structuring software - that is able to tkae teh gralbed msseage and "FIX IT". Eliminate the existing software in the human brain and I'd like to see the feat accomplished (I really would but I won't be holding my breath!). By the way, programming a computer to accomplish this won't cut it either since, obviously, the computer program is merely a substitute for the human software. I'm afraid the 'intelligence requirement' is there to stay - certainly in this case. The study is interesting for other reasons but it doesn't do squat to support evolution. Sorry to rain on your parade, Peter. Joralex

Here's a much more reasonable explanation: the data or information content of the words is not in the words, it's in our heads. Therefore it's easy for our heads to reconstruct the meaning because the meaning is already there.
By the way, programming a computer to accomplish this won't cut it either since, obviously, the computer program is merely a substitute for the human software. Software is software. If it can't be done by a computer then it isn't software.
Maybe you should begin stopping now? You know if I was as consistently wrong about stuff as you are I'd sure make a lot less smart-ass comments. But that's just me, I guess.

One example of where this breaks down is in words that are composed of the same letters such as tarp and trap. One can usually coax out the meaning due to context, but I suspect crash is correct: If the reader has a solid grasp of the langauge, he will be able to unjumble the mess, often unconsciously.

It would seem to me that the mind does have its limits on how complex a sentence can be before unscrambling a series of words becomes too difficult to automatically be deciphered.

quote: I shall accomplish installing sentences prior to intelligence deciphering meanings within. That makes no sense, crashfrog.
quote: ? violent parties to participate through cooperation ? extreme caution. I think the second word is supposed to be "necessitates," but the letters provided do not spell out "necessitates"...there's an extra "t" and is lacking an "e" and and an "s." I can only guess that the first word is supposed to be "producing," but the letters provided don't spell that ("predusing"?) At any rate, the rest of the sentence makes no sense. There is already evidence that a person who is a native speaker of a language has the functional comprehension of the language. It allows us to say something like, "Blank blanked the blank blank," and knowing that the first "blank" is a noun, most like a proper noun, the second "blank" is a verb (in past tense because of the "-ed"), and the third and fourth "blanks" are either an adjective/noun combination or a noun/adverb combination. You could put true nonsense in those places, but the physical structure of the sentence requires certain types of speech to exist in certain places. ------------------Rrhain WWJD? JWRTFM!

You are right the first makes no sense so I constructed the second one.Again I messed up and I have to apologize for that.The sentence translates as follows. Persuading violent parties to participate through cooperation necessitates extreme caution. I messed up by not including an 'a' in persuading so small wonder you missed that.I am curious though did you immediately recognize the pattern of the words I did spell correctly or did it require a drawn out process?
Oh. I must state that you owe crashfrog an apology as I am the author of both examples.

Interestingly this jumbing doesn't work in Hebrew.
The language is apparently compressed alreadyby the removal of vowels (or some such).

I didn't think it possible for two people to simultaneously miss the exact same point. Uhhh ... crash ... if it's "in your head" then may I ask, what IS IT that is "in your head"? That "meaning" that you speak of is a combination of things formally called 'vocabulary, syntax and semantics'. Nowhere except associated with intelligence are such things found. And the reason that we would be able to distinguish between 'tarp' and 'trap' is due to context considerations (as you've recognized) maybe mixed with some forward-scanning. Such actions are directly linked with an intelligence and, therefore, the rain continues on the Naturalistic parade. Joralex

The language is apparently compressed already by the removal of vowels (or some such). Now that's an interesting observation, Peter! Seriously, my background includes pattern recognition theory and one of the aspects that we investigated was that of 'redundant/extraneous information'. For example, if you saw the tip - and only the tip - of the nose of someone's face, would that information allow you to recognize who that person was? Probably not. So, at what point do you have "just enough" information to allow a positive recognition? Such was the nature of the questions that we investigated back then. Applying this here, how much may words (or even a language) be "compressed" while retaining recognizability? And, as you've observed, it appears that some languages have a higher 'compressibility potential' than others. Now, isn't all this much better than that ridiculous notion of 'evolution'? Joralex

I've not forgotten about it -- I am pointing it out
sepifically as the reason that data and information are not directly related. The 'data' is the "material carrier" of the information. Naturalistically speaking, show me any information that does NOT have a carrier. I'm afraid that within Naturalism you cannot separate the two, Peter; i.e., the two are directly related. The extrusion of information from data requires aninterpretive act ... so information in this sense cannot be applied to DNA, or if it is, it must be recognised that it is the interpretation of the data that forms the informaiton, not the data itself. Precisely my point! Tell me, WHAT performs the 'interpretation'? DNA encodes the information for the assembly of proteins (via base sequences) and something has to interpret those base sequences as meaning exactly what the code intends it to mean. But that interpretative act is conducted by a system that is ALSO encoded within the DNA. The mother of all chicken-n-egg? Adding or removing a base changes the data, it may or may notchanged the information. That is an unsubstantiated assumption. In fact, while the contents in your brain are able to help you retain the information in 'To be, or not be to', changing a base will likely yield an interpretation producing B instead of A. The quantity of information may have remained the same but it is the quality of information that determines life. The same addition/deletion could represent a gain or a lossof inforamtion dpnednig on context. Again, the quantity of information may have remained the same but it is the quality (i.e., the specificity) of information that determines many aspects connected with life. Thus, you are partly correct but the important part that you're missing is why the rain continues on the Naturalist's parade. Joralex

quote:Yep for for me the substantive may be the reverse "adding or removing a base" may change the information but it might NOT change the data. In 1992 I was doing research in the ANIMAL SCIENCE DEPT at Cornell and I speculated that it might be that Guanosine changes (in the base) could change the way the centriolar cycle cycles across generations (AND HENCE ACROSS THE CELL BLOCK CLONING PROBLEM , I had been hired to solve, If...)but this would NOT CHANGE ANY DATA, only how time IS SIMULATING THE electronic option to visualize the data.- J got that yellow read right and writed. Sorry for not seperating the quotes. I think we all "know" who said what.
