Editors’ Choice: Building Topic Models through Selective Document Exclusion

Earlier this month, I attended the ASIS&T 2011 Annual Meeting where, much to my delight, the paper I co-authored with Miles Efron and Katrina Fenlon 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.

Report: Linked Data for Libraries, Museums, and Archives: Survey and Workshop Report

In June 2011, Stanford University hosted a group of librarians and technologists to examine issues and challenges surrounding the use of linked data for library applications. This report summarizes the activities and discussions that took place during the workshop, describes what came out of the workshop, outlines next steps identified by the participants, and provides contextual and background information, including preliminary reports and biographies of workshop participants. The workshop report was produced and edited by the participants and staff at Stanford University Libraries.

Report: Developing the digital humanities at the Open University: progress report

In June 2011 the Open University Senate recognized Digital Humanities as one of two new University Thematic Research Networks, and it was launched at a colloquium on 8 July. During the coming months we plan to develop collaborative activity across the University, with a particular emphases on exploring how the use of digital technologies is shaping the research process, and on their potentialities for enhancing our mission of ‘openness’ in research.  Appointment of a Research Associate who will play a leading role in taking this process forward is currently underway. In the meantime for details of the ongoing programme of workshops and seminars, please see the Events page.
