Summary of 11th International Semantic Web Conference

Big Graph Data Panel at ISWC 2012

Big Graph Data Panelists (L to R): Mike Stonebraker, John Giannandrea, Bryan Thompson, Tim Berners- Lee, Frank van Harmelen

Last week, the 11th International Semantic Web Conference (ISWC 2012) took place in Boston. It was an exciting week to learn about the advances of the Semantic Web and current applications.

The first two days, Sunday November 11 and Monday November 12, consisted of 18 workshops and 8 tutorials. The following three days (Tuesday November 13 – Thursday November 15) consisted of keynotes, presentation of academic and in-use papers, the Big Graph Data Panel and industry presentations. It is basically impossible to attend all the interesting presentations. Therefore, I am going to try my best to summarize and offer links to everything that I can.

Linked Open Government Data: Dispatch from the Second International Open Government Data Conference

“What we have found with this project is… the capacity to take value out of open data is very limited.”

With the abatement of the media buzz surrounding open data since the first International Open Government Data Conference (IOGDC) was held in November 2011, it would be easy to believe that the task of opening up government data for public consumption is a fait accompli.  Most of the discussion at this year’s IOGDC conference, held July 10-12, centered on the advantages and roadblocks to creating an open data ecosystem within government, and the need to establish the right mix of policies to promote a culture of openness and sharing both within and between government agencies and externally with journalists, civil society, and the public at large.   According to these metrics the open government data movement has much to celebrate:  1,022,787 datasets from 192 catalogs in 24 languages representing 43 countries and international organizations.

The looming questions about the utility of open government data make it clear, however, that the movement is still in its early stages.    Much remains to be done to to provide usable, reliable, machine-readable and valuable government data to the public.

The Semantics of NASA’s POPS Project

The W3C recently interviewed Jeanne Holm, Chief Knowledge Architect at the Jet Propulsion Laboratory at Cal Tech. Holm also leads the Knowledge Management team at NASA. In the interview, Holm stated, “The goal of our project was to make it easy find expertise within an organization, or, as you’ll see, across organizational boundaries. The project is called POPS for ‘People, Organizations, Projects, and Skills.’ The acronym does not include E for Expert for a good reason: we tried three times to create a system with data specifically about expertise, but failed each time for different social reasons. Each attempt relied on self-generated lists of expertise. In the first attempt, people over- or under-inflated their expertise, sometimes to bolster their resumes. The second attempt prompted labor unions to get overly involved because greater expertise could be tied to higher pay. The third approach involved profiles verified by management, and that led to a number of human resources grievances when there was a disagreement. In all cases, the data became suspect.” Read more
