  • Running analytics on the CSCW corpora
  • My codebase at home was out of data, and I was having my missing bouncycastle jar file issue, so I updated the development folders. I also started updating my IntelliJ, which has taken 10 minutes so far…
  • First pass of running the CSCW data through the tool.
    There are three categories:
    • CSCW17 – these are the submitted papers
    • MostCited – These are (generally) the most cited paper by the author where they are first or last author. It took me a while to start doing this, so the set isn’t consistent.
    • MostRecent – These are the most recent papers that I could get copies of. Same constraints and caveats as above.
    I also deleted the term ‘participants’, as it overwhelmed the rest of the relationships and is a pretty standard methods element that I don’t think contributes to the story the data tell.
    Here’s the top ten items, ranked by influence of terms inside of the top 52 items in the LSI ranking. It’s kind of interesting…
    CSCW2017 Most Cited Most Recent Most Cited Most Recent

  • Finished rating! 530 pages. Now I need to get the outputs to Excel. I think the view_ratings should be enough…?
  • I don’t have just names alone, but I’m going to assume that the initial set of queries (‘board actions’, ‘criminal’, ‘malpractice’ and ‘sanctions’) may modestly improve the search. So with a proxy for the current system, with my small data set, I have the following results:
    • Hits or near misses – 46 pages or 16.7% of the total pages evaluated
    • Misses – 230 or 83.3% of the total pages evaluated

    With the new CSE configuration (exactTerms=<name permutation>, query=<full state name>, orTerms=<TF-IDF string>, we get much better results:

    • Hits or near misses – 252 pages or 78% of the total pages evaluated
    • Misses – 71 or 22% of the total pages evaluated

    So it looks like we can expect something on the order of a 450% improvement in results.

  • Good presentation on document similarity

7:00 – 5:00 VTX

  • Finished MostRecent.
  • Checked Data directory into SVN
  • Testing rating algorithms. Seems to be working pretty well 🙂
  • Rated all day. Should finish tomorrow.
  • Worked through paragon and fallen angel patterns with Aaron. Pulled out by bayesian spreadsheets and realized I no longer understood them…

Phil 6.20.16

7:00 – 7:00 VTX

  • Building chair corpus = Current and Cited
  • Filled MostCited.
  • Rating a few more pages. Still not getting any name hits.
  • Going to advanced search and entering items into each field, I get a different looking query: 
    https://www.google.ca/search?as_q=New+York&as_epq=Nader+Golian&as_oq=+license+board+practice+patient+physician+order+health+practitioner+medicine+medical
    • These seem to be the important differences
    • as_q=New+York — This is a ‘normal’ query
    • as_epq=Nader+Golian — This must be in the results
    • as_oq=+license+board+practice+patient+physician+order+health+practitioner+medicine+medical — at least one of these must be in the result
  • Going to add a test to look for the name in the query (and the state?) and at least check the NA box and throw up a dialog. Could also list the number of occurrences by default in the notes

    • Assistive technologies are not being designed right. We need to improve the design process.
    • That’s too general – give me a citation that says that technology abandonment WRT wheelchair use has high abandonment
    • Patrick responds with a bad design
    • Helena – isn’t the principal user-centered design. How has the HCI community done this before WRT other areas than wheelchairs to interact with computing systems
    • Helena – Embodied interaction is not a new thing, this is just a new area.Why didn’t you group your work. Is the prior analysis not embodied? Is your prior work not aligned with this perspective
  • How were the design principles used o develop an refine the pressure sensors?

  • Creating Friction: Infrastructuring Civic Engagement in Everyday Life
    • This is the confirming information bubble of the ‘ten blue links’: Because infrastructures reflect the standardization of practices, the social work they do is also political: “a number of significant political, ethical and social choices have without doubt been folded into its development” ([67]: 233). The further one is removed from the institutions of standardization, the more drastically one experiences the values embedded into infrastructure—a concept Bowker and Star term ‘torque’ [9]. More powerful actors are not as likely to experience torque as their values more often align with those embodied in the infrastructure. Infrastructures of civic engagement that are designed and maintained by those in power, then, tend to reflect the values and biases held by those in power.
  • Meeting with Wayne. My hypothesis and research questions are backwards but otherwise good.

  • Got the official word that I should be charging the project for research. Saved the email this time.
  • Continuing to work on the papers list
  • And in the process of looking at Daniele Quercia‘s work, I found Auralist: introducing serendipity into music recommendation which was cited by
    An investigation on the serendipity problem in recommender systems. Which has the following introduction:

    • In the book ‘‘The Filter Bubble: What the Internet Is Hiding from You’’, Eli Pariser argues that Internet is limiting our horizons (Parisier, 2011). He worries that personalized filters, such as Google search or Facebook delivery of news from our friends, create individual universes of information for each of us, in which we are fed only with information we are familiar with and that confirms our beliefs. These filters are opaque, that is to say, we do not know what is being hidden from us, and may be dangerous because they threaten to deprive us from serendipitous encounters that spark creativity, innovation, and the democratic exchange of ideas. Similar observations have been previously made by Gori and Witten (2005) and extensively developed in their book ‘‘Web Dragons, Inside the Myths of Search Engine Technology’’ (Witten, Gori, & Numerico, 2006), where the metaphor of search engines as modern dragons or gatekeepers of a treasure is justified by the fact that ‘‘the immense treasure they guard is society’s repository of knowledge’’ and all of us accept dragons as mediators when having access to that treasure. But most of us do not know how those dragons work, and all of us (probably the search engines’ creators, either) are not able to explain the reason why a specific web page ranked first when we issued a query. This gives rise to the so called bubble of Web visibility, where people who want to promote visibility of a Web site fight against heuristics adopted by most popular search engines, whose details and biases are closely guarded trade secrets.
    • Added both papers to the corpus. Need to read and code. What I’m doing is different in that I want to add a level of interactivity to the serendipity display that looks for user patterns in how they react to the presented serendipity and incorporate that pattern into a trustworthiness evaluation of the web content. I’m also doing it in Journalism, which is a bit different in its constraints. And I’m trying to tie it back to Group Polarization and opinion drift.
  • Also, Raz Schwartx at Facebook: , Editorial Algorithms: Using Social Media to Discover and Report Local News
  • Working on getting all html and pdf files in one matrix
  • Spent the day chasing down a bug where if the string being annotated is too long (I’ve set the  number of wordes to 60), then we skip. THis leads to a divide by zero issue. Fixed now

  • Going to go through the RQs and describe how to address them
  • Start with the back end and my local cohort, which I can assume to be diversity-seeking because of where they are.
  • Iteratively develop tool so that it gets used for diversity-related activities
  • Logs and questionairres.

Phil 6.8.16

6:30 – 4:30 Writing

  • Wondering if I should add a section on trust and credibility
  • Huh – just saw this on Google image search. You get a bar of context words that allow for drilling down into a result
  • Reworked a lot of the paper since the whole anonymous part has been shelved
  • Started on the hypotheses and research questions in the plan section

  • More on libraries and serendipity. Found lots, and then went on to look for metions in electronic retrieval. Found Foster’s A Nonlinear Model of Information-Seeking Behavior, which also has some spiffy citations. Going to take a break from writing and actually read this one. Because, I just realized that interdisciplinary researchers are the rough academic equivalent of the explorer pattern.
  • Investigating Information Seeking BehaviorUsing the Concept of Information Horizons
    • Page 3 – To design and develop a new research method we used Sonnenwald’s (1999) framework for human information behavior as a theoretical foundation. This theoretical framework suggests that within a context and situation is an ‘information horizon’ in which we can act. For a particular individual, a variety of information resources may be encompassed within his/her information horizon. They may include social networks, documents, information retrieval tools, and experimentation and observation in the world. Information horizons, and the resources they encompass, are determined socially and individually. In other words, the opinions that one’s peers hold concerning the value of a particular resource will influence one’s own opinions about the value of that resource and, thus, its position within one’s information horizon.
