New and Emerging Legal Infrastructures Conference (NELIC)
From the post:
The New and Emerging Legal Infrastructures Conference (NELIC) was held April 15, 2011 at Berkeley Law School in Berkeley, CA. It brought together the lawyers, entrepreneurs, and technologists who are working to build the next biggest disruptive technologies in the legal industry.
The aim of the conference was to provide a meeting point for a deep and substantive discussion about the long-term impact of these technologies, and how they might come to be broadly adapted in the industry as a whole. It tackled the topics of quantitative legal prediction, legal automation, legal finance, the design of user-facing interfaces that make it possible for laypeople to manage the law, and startups in the legal industry.
The entire conference is available on videos.
Looks like a good resource for finding places where topic maps would make a substantive contribution.
