Ning: Andreessen gets into social networking

The Globe and Mail has a story, Andreessen gets into social networking, on Ning, a “platform” for creating your own social network. It’s like an open FaceBook that lets you create a network for your family or for a class. You can create private or public networks; the public ones are visible and you can join them. You can pay Ning to make money off ads and for other services. Andreessen is, of course, the famous founder of Netscape. (So this is what he is up to now.)

Ning has a nice simple interface for choosing what you want on the portal. You drag the modules you want to the different columns. It lets you see what you can have and lets you arrange what you want.

State of the Union Visualization

SOTU Visualization ImageBrad Borevitz of onetwothree.net has developed another visualization of language in presidential State of the Union Addresses at State of the Union. He calls it a “data toy” and it combines a number of different graphs. One nice feature is that if you click on one Address and then another the word cloud for the first appears behind (and in red) the second for comparison purposes.

I have blogged other such visualization toys that use the State of the Union Addresses like State of the Union Parsing Tool and the SOTU Rich Prospect Browsing of the New York Times.

We Are Smarter Than Me

We are smarter than me logoWe Are Smarter Than Me is a large scale community writing experiment led by Wharton Business School, MIT Sloan School of Management, Pearson, and Shared Insights. They are inviting hundreds of thousands of people to contribute to the writing of a book about “a crucial shift in how businesses operate as they learn to leverage the power of ‘community.'” (Overview) In other words, a community written book about community business.

The site provides an interesting list of applications of community power in business, Community Reference. The Community Proposal page describes the book structures they propose to manage writing.

Thanks to Terry for this.

CNW Group: Mediavantage

Logo for MediavantageThe CNW Group that has it’s Canadian base in Toronto has a new service called MEDIAVANTAGE that has many of the features of a multimedia news crawling, managing, and visualizing service. From the Flash intro it looks like users define keywords to track. Mediavantage then shows you results from different sources. It can send alerts and graphs result history.

The interesting part is that they track TV news and provide text summaries that look like the text off close captioning. Subsets of results can be shared by e-mail and PDF. This is a news mining tool for business that offers a model for what Web Mining for Research might look like.

Thanks to Terry for this.

Web Mining for Research

What’s Web Mining for Research is a white paper I wrote on the TADA wiki trying to define an emerging research practice that draws on the web as evidence of human behaviour. I’m not happy with the phrase, but it hard to know what to call it. Text mining refers to mining large text databases, not the web. Web mining means all sorts of things. What stands out for me as important is that we have in the Web a massive body of evidence for philosophical and cultural analysis, something we haven’t had before. While a chance in evidence may seem trivial, the resulting change in research practices is not.

Plagiarism

Like most profs I have had to deal with plagiarism cases. Over the years I have become convinced that the problem is not the odd cheater, but students who have developed habits. My hypothesis is:

Prepatory colleges in Canada that prepare foreign students for acceptance to Canadian universities are a breeding ground for writing coping tactics. Students who go to these schools unprepared for high school writing in English, learn from their peers a collection of tactics that let them get by. Because of the family pressure to succeed and the short time they have to learn to write in English, they have to avail themselves of these tactics and don’t feel they have the luxury of really trying to write in their own voice. We make matters worse by, on the one hand threatening them with expulsion if caught, and on the other hand offering no real alternative tactics or writing courses with individual attention in the first year. Further I suspect that:

  • Students know that plagiarism is an integrity issue, but are more scared of failure. Even if students don’t understand all the nuances of plagiarism they know they can’t write the way they can in their native language.
  • Students fool themselves by thinking it doesn’t matter for the moment, or that this is what everyone does, or that they will learn it later.
  • We fool ourselves into thinking that it does matter in the work world the way it does to us when, in fact, in many situations a report cribbed off the web that answers questions is good enough. There is even software to support such cribbing, see Net Snippets.
  • Students in this situation don’t trust staff or their professors to help them as they are committed to coping tactics and don’t have the oral communication skills to get navigate help without admitting they are doing something they know is wrong.
  • Students are using a variety of tactics and find it easier to modulate tactics or acquire new ones than to start writing. These vary from collaborating to buying essays.
  • These tactics are successful at getting passing grades on writing assignments.
  • Native English writers are a very different problem and interventions aimed at them won’t work with ESL students. Most plagiarism modules are aimed at native writers.
  • ESL and native writers have realized that in the economics of education it costs under $100 to buy a cust written 5-page paper that will not get caught and will get a B for the assignment. This is less than the cost of textbooks for a course.

In short, with ESL students we are dealing with habits formed before they come to university and habits are not changed the way exceptional behaviour is. Habits are changed by understanding them, understanding the triggers, providing alternative tactics, and motivating students to try alternatives.

A good site on plagiarism is, Assessing Student Learning – five practical guides from the University of New South Wales. PLAGUE is a special interest group based at Monash University who are researching the issue. See their papers and links.

Web Mining for Research

Web Mining for Research is a white paper I’ve just written to get my ideas down about how we should be using the Web as evidence not just for social science research, but in the humanities. Digital humanities is more than studying old wine in new digital bottles – the challenge is to do humanities research using the digital as evidence. For me the challenge is how to rethink philosophy now that we can mine concepts in their sites, to paraphrase Ian Hacking.
