And more specifically stripped. Incredible song. Or for that matter kokain. Man those riffs just drive you out of your mind dont they.

Filled up a survey today, about some perception thing, of companies recruiting on campus. Was so totally painful. I dont really understand. Why did I spend so much time filling it up. There was this HUGE matrix, which had to be filled with my opinions. Someone did not tell them things properly. I dont have opinions. Not atleast as many to fill up that monstrous matrix of theirs. Well, I did try, for a while. As i tried to form opinions on the spot and them put them on paper. Do you know how hard it is to form opinions on the spot? It is. And if you are finding it easy, you dont form opinions, you just think you do. Trust me on this. :)

One of the most incredible things is the fact that most people around you dont bother to form opinions. They have a few of their own opinions. You can figure out that this is their own opinion when people can be completely irrational about it and its consequences. But most other opinions you see around are only the sum total of the opinions formed from the positive part of your sphere of perception, that is all.

Okay, enough of rambling. Lets continue with the discussion we were having last. In the last post, we talked about the a number of definitions that led to the definition of the LSI or the linear scale of information. Given any observation, it can be located on this scale. What is an observation. An observation is any representation of a Data Source or DS. A photo is an observation of some reality. A word is an observation of some idea. A poem is an observation of some emotion/idea. A simple sentence also is an observation. So is a complex mathematical model of the universe.

One peculiarity about the LSI should be kept in mind. The LSI stretches from 0 to infinity. It is unbounded on the upper side. This means that a DS lies at infinity, and a completely useless bit of information lies at 0. We define data to lie in the small reaches, closer to 0 on the LSI. Information, relatively is higher on the scale. It represents a higher richness of data about a particular DS. Knowledge tends towards the object itself. A picture, worth a 1000 words, is therefore higher on the LSI with respect to the words it replaces.

This can be extended to any object, idea, thought or any other information content without any modifications. We can therefore use this structure to compare and develop better and higher forms of information management systems. That is what is envisaged as the end objective of this study. This structure can be used to describe any informational content with ease. We will go into details about the implementation of this structure soon, but before that we shall look into the way this method can be used to model interactions.

We define an interaction to be a process that allows for transfer of data between a DS and a DA using a Data Transfer Medium. This is the simplest definition of an interaction. An interaction can give rise to one of the following results. Information will be transferred from the DS to the Data Acquirer. In addition, the DS can change its state due to the interaction of the DS with the DTM (also known as the medium). Further, the interaction between the medium and the DA, will cause changes in the DA. Note that these changes are in addition to the simple transfer of information that can be attributed to the interaction.

This in fact follows from the defnitions we had seen yesterday. We have already talked about a query that is used by the DA to get information from the DS. Now when the query travels from the DA to the medium, the medium has obtained information. This causes a change in the medium itself. When the query is transported to the DS, the DS undergoes changes because of the informational content in the query. The exact similar process occurs when the DS replies with the answer to the query. The reader may note that no change occurs in the DA during the asking phase of the query, and no change happens in the DS during the reply phase. The DTM undergoes change twice, with both the query and the answer.

Lets see some practical explanations of the entire structure. Any systemic structure can be abstracted using this. In fact, now with the addition of the term interaction, we can now model dynamic changes in systems too.

Mail me, if you think there is some structure that cannot be abstracted using this framework. We will go into more practical considerations using this framework in later posts.

This is the first time that I actually continued a post beyond just one post. That must mean, I dont really think this idea to be crap.
