Resource: Ways to Compute Topics over Time, Part 4

Tue, 07/11/2017 - 12:00

From the resource:

This is the last in a series of posts which constitute a “lit review” of sorts, documenting the range of methods scholars are using to compute the distribution of topics over time. The strategies I am considering are:

Average of topic weights per year (First Post)
Smoothing or regression analysis (Second Post)
Proportion of total weights per year (Third Post)
Prevalence of the top topic per year (Final Post)

To explore a range of strategies for computing and visualizing topics over time from a standard LDA model, I am using a model I created from my dissertation materials.

Editors’ Choice: Disrupting The Silicon Valley Department of Education

Tue, 07/11/2017 - 11:00

First, Silicon Valley entrepreneurs are seeking to disrupt education in the same way its technologies have disrupted other areas of everyday life, from hailing a cab and booking accommodation to finding a date or looking after your health. The main concept Silicon Valley uses to explain its focus in education is “personalization,” as demonstrated by startup schools like AltSchool, Khan Lab School and the Summit Schools network.

The Stanford University education technology researcher Larry Cuban has been reporting on some of these new schools based on a series of lesson observations. Though he remains skeptical of their capacity to “scale-up” beyond the sites where they have started-up in Silicon Valley itself, he has also reported admiration for their synthesis of progressive, inquiry-based pedagogies and efficient, administrative uses of data analytics to support personalized learning.

Second, though, Silicon Valley has set itself the challenge of educating young people to be able to live and thrive in the disrupted world — that is, “to rule the machines.” The way it hopes to achieve this aim is through teaching kids to code.

One such effort, according to Natasha Singer in the New York Times, is the learning to code organization Code.org, “a major nonprofit group financed with more than $60 million from Silicon Valley luminaries and their companies, which has the stated goal of getting every public school in the United States to teach computer science. Its argument is twofold: Students would benefit from these classes, and companies need more programmers.”

Resource: Ways to Compute Topics over Time, Part 3

Thu, 07/06/2017 - 13:00

From the resource:

This is the third in a series of posts which constitute a “lit review” of sorts, documenting the range of methods scholars are using to compute the distribution of topics over time.

Graphs of topic prevalence over time are some of the most ubiquitous in digital humanities discussions of topic modeling. They are used as a mechanism for identifying spikes in discourse and for depicting the relationship between the various discourses in a corpus.

Topic prevalence over time is not, however, a measure that is returned with the standard modeling tools such as MALLET or Gensim. Instead, it is computed after the fact by combining the model data with external metadata and aggregating the model results. And, as it turns out, there are a number of ways that the data can be aggregated and displayed.

Resource: Full Draft of Theory & Craft of Digital Preservation

Thu, 07/06/2017 - 12:30

From the resource:

This weekend I’m submitting the full draft of the manuscript for my book The Theory and Craft of Digital Preservation to the publisher, Johns Hopkins University Press.

I’ve had a lot of fun working on this on nights and weekends over the last year. I have also learned a ton from everyone who has read drafts of the work in progress.

I’ve had a few folks reach out to me after reading parts of drafts and say things like “I’d love to read more of this. When will it be out?” I’m not sure exactly how long it will take for the next round of review and all the improvements that will come from working with a great press. With that said, drafts of the entire book are now online. Instead of having folks pick through my previous blog posts with the links, I figured I would put them all together in order in this post.

Editors’ Choice: Standard Practice – Libraries As Structuring Machines

Thu, 07/06/2017 - 12:00

As Lawrence Busch has put it, standards and related forms are “the ways in which we order ourselves, other people, things, processes, numbers, and even language itself.” Standards enable access to things, allowing social worlds to interact. Standards tell cars when to stop and go. Standards direct the flow of water and power. In libraries, standards do similar work, enabling some ways of knowing and being and not others due to the pathways they create through space. Users must adopt the vocabulary of the knowledge organization scheme to efficiently retrieve books on a topic, opting for Gays or Lesbians rather than Queer or Same-gender-loving or any of the myriad terms people use to describe their sexual selves or communities. David Wojnarowicz’s accounts of life with AIDS under Reagan will be classified with other books about AIDS (Disease)—Patients, reducing his fiercely political text to the story of an individual sick body. Librarians at the reference desk will smile, whether that smile is culturally or contextually appropriate. Standards have material effects in libraries.

Standards are not, of course, wholly determinative. Even when paths are clearly marked, walkers will move as they want to. As Adler argues, readers in libraries make their own meaning from the rigid designations on the shelves, reading “perversely” to tell stories other than those told by the classification schemes. And in digital spaces, search and retrieval is not bound by the same kinds of conventions as traditional library systems. If the card catalog enabled patrons to search only by author, title, and subject, the database expanded search to include keywords. Once the internet arrives, search and retrieval sidesteps completely controlled vocabularies and categories structured in advance. On the internet, we can sustain a fantasy of freedom.

And yet, digital spaces are constructed just as much by standards, though the stories they tell may be more difficult to parse.

Editors’ Choice: A Naive Empirical Post about DTM Weighting

Thu, 07/06/2017 - 11:00

In light of word embeddings’ recent popularity, I’ve been playing around with a version called Latent Semantic Analysis (LSA). Admittedly, LSA has fallen out of favor with the rise of neural embeddings like Word2Vec, but there are several virtues to LSA including decades of study by linguists and computer scientists. (For an introduction to LSA for humanists, I highly recommend Ted Underwood’s post “LSA is a marvelous tool, but…“.) In reality, though, this blog post is less about LSA and more about tinkering with it and using it for parts.

Like other word embeddings, LSA seeks to learn about words’ semantics by way of context. I’ll sidestep discussion of LSA’s specific mechanics by saying that it uses techniques that are closely related to ones commonly used in distant reading. Broadly, LSA constructs something like a document-term matrix (DTM) and then performs something like Principle Component Analysis (PCA) on it.1 (I’ll be using those later in the post.) The art of LSA, however, lies in between these steps.

Typically, after constructing a corpus matrix, LSA involves some kind of weighting of the raw word counts. The most familiar weight scheme is (l1) normalization: sum up the number of words in a document and divide the individual word counts, so that each cell in the matrix represents a word’s relative frequency. This is something distant readers do all the time. However, there is an extensive literature on LSA devoted to alternate weights that improve performance on certain tasks, such as analogies or document retrieval, and on different types of documents.

This is the point that piques my curiosity. Can we use different weightings strategically to capture valuable features of a textual corpus? How might we use a semantic model like LSA in existing distant reading practices? The similarity of LSA to a common technique (i.e. PCA) for pattern finding and featurization in distant reading suggests that we can profitably apply its weight schemes to work that we are already doing.

Editors’ Choice: Computers & Writing Session F1 – Critical Making As Emergent Techne

Thu, 06/29/2017 - 11:00

The panel “Critical Writing as Emergent Techne” worked with both criticality and technology, showing how both critical discourse and hands-on, constructive practices could reinforce each other in the college writing classroom.

Anthony Stagliano opened the session with a paper that situated “critical making” as a position that works to avoid both the “Scylla” of self-destructive or naval-gazing skepticism/criticality and the “Charybdis” of an over-excited indulgence in technology in the classroom simply for the sake of technology. The critical maker, Stagliano said, looks at technology with a subversive but playful eye, looks to see how the technologies work, how they can be opened up and modified, how they may be used to challenge the status quo, and how they can lead to perceptual shifts in conversations, in what can be done, what can be seen. “Critical making at its best is affirmative rather than negative,” Stagliano said; it’s about affirming possibilities, seizures, and perversions.

Bree McGregor offered her take on critical making in a video that explored her work with critical making in an online class. McGregor wanted to subvert common assumptions about online classes. Students believed that because the class was shorter, only a handful of weeks, and that it was online, there would be less rigor and less interaction required. McGregor sought to work against these expectations by involving the students in critical making exercises. In the class, students were immersed in “maker spaces” which demanded hands-on, tactile rhetorical constructs.

CFParticipation: Epoiesen – Call for Respondents

Tue, 06/27/2017 - 13:00

From the post:

I’m hoping to get Epoiesen unveiled in time for the autumn. You remember Epoiesen . Part of the idea is that we don’t do traditional peer review, but rather ask reviewers to be ‘Respondents’, who react to the piece in a short creative work on their own. We seek out at least two ‘Respondents’ (ideally) for every submission. The ‘Responding to…’ will itself be published with its own citation, DOI, etc. A response explores how the piece moves the responder, or puzzles her, or sparks new thoughts – a ‘Response’ is meant to become the starting point for a larger discussion that would take place via the site’s annotation framework (readers can annotate any piece of text on the site using Hypothes.is), across the blogosphere, and beyond.

Announcement: The Library of Digital Latin Texts (LDLT)

Tue, 06/27/2017 - 12:00

From the post:

Within the next year, the Digital Latin Library, in partnership with the Society for Classical Studies, the Medieval Academy of America, and the Renaissance Society of America, will launch The Library of Digital Latin Texts (LDLT), a series of digital critical editions of Latin texts from all eras. The DLL will provide the encoding guidelines, infrastructure, and platform for publishing these texts, and the learned societies will be responsible for receiving submissions, reviewing them, and deciding whether or not to publish them. Policies and procedures for this endeavor are still in development, but it seems worthwhile in the meantime to explain what we mean by “digital edition” so that prospective editors can begin preparing submissions.

Resource: This Political Moment – Resources for Educators in the Trump Era

Tue, 06/27/2017 - 11:30

From the post:

Educators have long been responsible for supporting the growth and development of all young people. The job of designing engaging lessons, promoting respectful discussion, creating an inclusive classroom, and preparing youth for life in democratic society is never an easy one. We expect educators to perform these and countless other feats on a daily basis. And, this particular political moment is especially challenging. Characterized by record-high indicators of polarization and ideological discord among our major political parties, this political moment has made educators’ routine job duties remarkably challenging and ever-important. What follows is a brief overview of a few of the significant challenges that face educators today. This document also provides a handful of supplementary resources to support equitable teaching and learning in this political moment (accessible through the open-access hyperlinks).
