180 Day 13 Notes

Feb 26, 2001

1. One minute papers (both last Monday plus last wed)

Last monday

Main Point

Give people options and versatility

Agile views, look aheads, enriched links

Everything is connected

Q:

How will look aheads/enriched links work with ADA compliant browsers?

Since search embedded in real problems, how are paths/directories deficient?

Is there danger of offering too many views (either overload user or lose structure)?

How could agile views be used in OPACs?

Are these techniques used? Successful?

More RB examples? (see web site), next steps?

Why called agile views (is speed the only factor?)

Get involved in open video?

Last wed

Main Point

Relevance is relative and quality is personal (but what about bridges?)

Q:

Do people really expect a definition of relevance, or is the process of seeking a def the point?

What kinds of research on searching is underway?

Isn’t your ISP a personal filter?

So we want machines judging relevance for us?

What is bibliometrics?

Interview a search engine article?

Background on link analysis?

Do people care about relevance? Quality?

Can SE both map search history and protect privacy?

2. Assessing the Value of Information—the key to intelligent USE

We have read and discussed theoretical notions of relevance. We will now consider the practical notions of the value of information.

A. Compare the value of an information unit [factoid/document] versus the value of the process of extracting that unit.

The IU’s value is dependent on the USE of this information—we can link this to real capital (like labor, intellectual property, etc.)

The value of the process is dependent on the individual (organization?)—we can perhaps link this to psychological or social capital.

B. Is information value absolute or relative?

Consider these question

Knowing Lee’s plan of attack at any point in the Civil War today is interesting but has a different value than it did the night before. [consider time]

Knowing that pressure stops bleeding [consider criticality, universality]

Knowing that Carlos Santana won best album Grammy [consider application scope]

Knowing about safe sex practices [consider age]

Are there some fundamental information that are universally known?

Are there basic information rights (presumably, these would have very high value)?

3 Reading discussions this week
