Explicit data, Implicit data


Heidegger, says that "the meaning of a particular thing is enabled by the web of implicit meanings we call the world"

This quote is referring to the web of knowledge that allows humans to understand words. It relies completely on the idea that things can be categorized. For instance my favorite thing to drink is mountain Dew. Boom your braid just did what Heidegger is talking about. At the very least you know that what I like to drink is a liquid, that it is not poisonous, and that it’s the thing that I prefer to drink over all others. You were able to deduce this from my assertion that I enjoy drinking this thing. Drinking carries with it the implicit idea that something that is drank must be liquid. I believe that Weinberger used the example of a bird to show a similar idea. To someone who has no concept of what a bird is then telling them something is a bird is worthless. However if the concept bird is understood by someone then anything you tell that person is a bird will automatically have feathers, a beak, and wings.

The is a problem with the third order of order and the idea of implicit knowledge. The problem is that the third order of order tries to break everything down into separate parts and then rebuild words as a way to organize things. For instance if I had a picture of a pelican I would tag it with all the information needed to understand the picture. Pelican, Bird, Feathers, Fish, Flying, Ocean. The problem is that all these tags carry the same weight. According to the tags the word fly and bird are equally related to the picture. Now lets approach the system from the others side. Say I am reading a book and it talks about the constant buzzing of a fly that is circling a characters head. I want to see what this fly looks like so I type fly and wings into a image search that uses tags. This is utterly unhelpful because it returns thousands of images of birds, bats, planes, and insects. If I know that I am looking for an insect then I might have a chance of finding a picture of a fly but that knowledge is implicit. So that is the problem with the third order of order. It requires the user to already know some implicit information about what they are looking for. It offers no help to a user who is unversed in the implicit connections of the culture the system is designed for.

The Hanging Tree:
Are you, are you
Coming to the tree
Where they strung up a man they say murdered three.
Strange things did happen here
No stranger would it be
If we met up at midnight in the hanging tree.

Are you, are you
Coming to the tree
Where the dead man called out for his love to flee.
Strange things did happen here
No stranger would it be
If we met up at midnight in the hanging tree.

Are you, are you
Coming to the tree
Where I told you to run so we’d both be free.
Strange things did happen here
No stranger would it be
If we met up at midnight in the hanging tree.

Are you, are you
Coming to the tree
Wear a necklace of rope, side by side with me.
Strange things did happen here
No stranger would it be
If we met up at midnight in the hanging tree.
