  1. Ist 331 class 4 • 4 yorkshiremen • Computers still off, ist331 in subject • Readings notes come in • Groups, 2-person, and flks who are new • Will move next week • Questions? [10] • Project choice [5 min], moved back • PQ4R, how to work with memory (review) [5] • Barnes et al. 1996 [12] • IS lab [40]

  2. §5.2.3 (PQ4R) • Preview • Question • Read • Reflect • Recite • Review What is it? Who is it by? What does it say? What does it imply? Do we believe it? So, begin with the end in mind, chapter 14…

  3. Cognitive Architecture to Summarise how people think

  4. ABCS • Anthropometrics • Behavioral, perceptual psychology • Cognitive • Social • Task analysis • Risk driven spiral model, how will systems fail because users are not supported and could have been, cheaply and easier than costs to do so?

  5. Barnes et al. 1996 [12min] • What is it? • Who is it by? • What does it say? • What does it imply? • Do we believe it?

  6. IS Lab • Choose a task/topic/question to examine • you could use a Java program to parse one of these files, and they could quite do the whole set • but you start to see some tradeoffs; • if you do it by hand, you can go through a thousand queries • by splitting with your group members you might go through 4k queries • you really understand them but you have only four thousand • on the other hand if you use a Java program, you can analyse a million queries, but you cannot understand them as well...

  7. Tradeoffs in analysis • That is one of the fundamental tradeoffs in this area, whether your study users, or drivers, or website visitors • you can either understand a few in great detail and depth, or you can understand all of them very superficially. • If you look at the data it might influence what you will look for in the data. That is ok.

  8. Details of the data available • That is the first lab, what you are asked to do is to do whatever you want, in the framework of the lab. 150 MB data. It is a lot. • It is a set of a set of search queries. There is Yahoo, Altavista, and a couple of other engines. It is a listing of what queries users type into the search engines. • Pick among those sets of data and choose what your group wants to do. • One group can look at the first data set and look at what is the average number of words per query.That is a perfectly reasonable lab although it’s a bit boring.

  9. Possible topics • The lab is designed to make you see how far this process can be and see how successful you can also be. • You could also look at how many queries were about sex, and not about sex. • Websites that sold kumquats. • How often is pennstate mentioned. • How many have google in it? Are there common abbreviations used? How many records where returned? Is your site/topic/area mentioned? • If you look at the literature, some say that users only look at the first page. But some others say that some users look at 10s of pages. Both are true. • I will give you 20 minutes to discuss what you want to do • If one of your groups member is not here, today you are authorized by me to make a decision for him, and if they contest this decision you can send them to me. • It is one of the hardest project you will have if you struggle with it. It is one of the easiest project you will have if you engage it. • That is very much like a real world project.
