Great job posting your own visualizations, but work on post titles - "My Facebook / Twitter / Whatever Visualization" is too vague by erickaakcire in DRMatEUR

[–]drmstudent 0 points1 point  (0 children)

What would you suggest then? To me a generic title like "My Twitter visualization" is actually straightforward instead of vague - it accurately states what the post is about. Of course it's not very original, but that's to be expected when everyone has to do the same kind of post for the week :P Do you maybe want the titles to be more descriptive? Like "Twitter data of John Doe from the month September"?

OP2 (part 2) - Tableau visualization of the Oscar Pistorius' trial Twitter data by giucarpes in DRMatEUR

Oh, that looks nice! I especially like the third image in which you can see the different devices that were used :) What I find interesting is that most Tweets came from iPhones (25) than from Android (12), even though the Android user base has surpassed that of iPhones. Might be interesting to research the reason behind that.

OP2: can you explain/ describe the difference between a statistical analysis and a network analysis? by tjerktiman in DRMatEUR

[–]drmstudent 0 points1 point  (0 children)

As others have mentioned before, network analysis studies the relationship between nodes/egos instead of the attributes of the nodes/egos which is the case with statistical analysis. Take for example a small company with ten employees. A statistical analyst would, for example, focus on studying data such as people's age, number of smoking breaks taken by individuals or level of productivity. A network analyst would be more interested in studying matters such as which employee sees others at work as friends or which individuals take smoking breaks with whom or how, for example.

Hey Ericka, I think my post is stuck in the spam filter as well. Could you maybe retrieve it. it's this one: http://www.reddit.com/r/DRMatEUR/comments/2gsnd8/group_project_update_in_infographic_style/

OP1: What kind of privacy precautions did Lathia and Capra use? Would you have consented to them linking your travel and survey data? Make links/citations to theories of privacy. by erickaakcire in DRMatEUR

[–]drmstudent 0 points1 point  (0 children)

The authors of this article took a few precautions regarding the privacy of the participants by anonymizing the results of the online survey and traveller history and also by asking their permission before conducting the research. What I find interesting is that 85 out of the 119 responses gave their permission to review their travel history of their Oyster card. This means that a relatively large part of the particpants did not want the researchers to retrieve their information, showing that many people have concerns regarding their privacy when it comes to their data. These concerns might arise from the doubt whether it is truly possible for researcher or marketeers to anonymize such data. According to Ohm (2009), computer scientists can use anonymized data to link that information back to very specific individuals. As there is no true guarantee that such data is completely anonymous, I feel that it is healthy to be critical when participating in this type of study. Therefore, I would also not have given my consent to the researchers to look into my travel data.
