Pico Safari: Active Gaming in Integrated Environments

With the recent release of Pokemon Go, I’m posting my presentation notes from for designing a similar game called Pico Safari in collaboration with Lucio Gutierrez, Garry Wong, and Calen Henry in late 2009. The concept of virtual creatures in the real world follows so nicely from the technological affordances of the past few years, with ARG-enabling technologies in our phone and the evergreen motivation of “collecting stuff” (Remember victorian-era insect collecting?).

The talk below was presented at SDH-SEMI 2011, earning the Ian Lancashire Student Promise award.

A Modern Proposal

Last month, I gave a presentation about paid crowdsourcing in the humanities at SDH-SEMI. Below are my notes.

In a 2004 talk, John Unsworth characterized the dominant model of the humanities as one of appreciation– rigorous and qualitative. By examining a work from multiple angles and multiple contexts, our belief is that we can learn “notice things about it that have never been noticed before, and increase its value.“ Such research does not easily lend itself to large-scales like quantitative work does: qualitative undertakings, ones of concentrated appreciation, are restrained by the amount of human involvement available.

However, as we explore new ways to utilize our digital environment for humanities research, so-called ‘big data’ approaches are not only becoming possible but inevitable. The archival efficiency of computers coupled with the digitization efforts of historians, librarians, and digital humanists has resulted in endless bytes of data to understand and call our own, while the offline limitations of scale have left a large area of questions thus far unturned.

There are numerous approaches for scaled up humanities research. Today, I’ll speak of one in particular: crowdsourcing. In doing so, I’ll describe how crowdsourcing is currently being undertaken and share a project of my own – one where semi-anonymous online users rewrote Jonothon Swift’s A Modest Proposal – as one approach to crowdsourcing workflow.

Building Topic Models through Selective Document Exclusion

Earlier this month, I attended the ASIS&T 2011 Annual Meeting where our paper was selected for the Best Paper Award.

In Building Topic Models in a Federated Digital Library through Selective Document Exclusion, we presented a way to improve the coherence of algorithmically derived topical models.

The work stems from topic modeling we were doing, first with PLSA and later LDA, on our IMLS DCC research group. The system we are working with brings together cultural heritage content from over a thousand institutions and, as a result contains quite diverse and often problematic metadata. This noise presents problems for inferring strongly coherent topic models, so Miles came up with the successful idea of identifying and removing topically weak documents from topic training. The paper outlines how this was done and the outcomes.

I encourage you to look through the full paper, which is fairly accessible, or the press release.
