Linked Data on the Web Workshop at WWW 2012

Juan Sequeda photoThis year was the 5th version of the Linked Data on the Web Workshop co-located at the World Wide Web Conference going on in Lyon, France.

At this workshop, seven issues caught my attention:

1) Media: Yunja Li presented on Synote: Weaving Media Fragments and Linked Data. This is interesting for those who not only want to link to an entire video, but want to link to a part of a video at a specific interval of time, and also add metadata information about that.

2) NLP to Linked Data: How can we relate the results of different named entity extraction tools to Linked Data. Giuseppe Rizzo introduced their project, NERD, which is working on this area.

Captivating Presentations from LDOW2012

Ivan Herman recently offered a recap of some of the most intriguing presentations at the recent Linked Data on the Web Workshop in Lyon. Herman writes, “Giuseppe Rizzo made a presentation related to all the tools we know have to tag texts and thereby being able to use these resources in linked data (“NERD meets NIF: Lifting NLP Extraction Results to the Linked Data Cloud”), i.e., the Zemanta or Open Calais services of this World. As these services become more and more important, having a clear view of what they can do, how one can use them individually or together, etc., is essential. Their project, called NERD, will become an important source for this community, bookmark that page.” Read more

Google, Yahoo!, Bing, and Yandex all rely on structured data markup in HTML pages to improve the display of search results, making it easier for people to find the right web pages. Last June, these search engines announced a joint initiative called is a shared markup vocabulary that webmasters can use to describe information in their pages in ways recognized by these major search providers. This panel will explore the current state of standards activities, tools, and implementations of with leaders from the effort and W3C.

Mphasis on Semantics in Retail

This year’s National Retail Foundation’s Annual Convention & EXPO, also known as “Retail’s Big Show,” is going to feature a session entitled Profiting from Semantic Web in Retail: The new tool of successful practioners in Customer Experience and Operations. The session will be led by Mphasis, an HP company. According to the description, “IT and data practices have always needed humans to interpret the data and act on results. The Semantic Web aims to make data intelligible to computer systems, and is already leading to applications where computer systems replicate the nuanced decision making of humans. In this session we introduce Semantic Web concepts and ways in which retailers are already putting it to use to enhance customer experience and achieve orders of magnitude changes in operating efficiency.” Read more

Semantic web and linked data technologies are built around a simple data model that makes it easy to share and combine data from disparate sources across the public internet or across silos on a private intranet. SPARQL is the query language standard from the W3C (the same standards body that brought us HTML, CSS, and XML) for querying this data. A variety of free and commercial software implementations have made it easy for people to get started with SPARQL and to incorporate it into applications that take advantage of the growing availability of linked data on the web.

#SemTechBiz Keynote: Semantic Technology at The Library of Congress

Laura Campbell, CIO, Library of CongressLaura Campbell, CIO of the Library of Congress, spoke at the recent SemTech Conference about how the world’s largest library leverages semantic technology to help manage the vast resources of the LoC.

The Library of Congress is “more than just a library,” said Campbell, pointing out that the LoC has “the Congressional Research Service, the Copyright Office of the U.S., and the Law Library in addition to the National Collection.” With over 146 Million items in 470 languages, represented in both analog and digital content, and with newly gathered material regularly being added from around the world, there is undeniably a lot of content to manage.

In her keynote address, Ms. Campbell spoke about how the Library of Congress is leveraging linked data technologies in three key areas:

  1. Managing existing collections
  2. Maintaining the LoC’s role as a leader in the distribution of canonical information
  3. Fulfilling the mission to collect, preserve, and provide access to a more digital collection

The keynote in its entirety, is presented below.

#SemTech Spotlight on IBM Watson

At the 2011 SemTech San Francisco, there was a special presentation by Aditya Kalyanpur, of IBM Research. Kalyanpur was part of the algorithm team on the Watson project. You remember Watson, right? The computer who won Jeopardy earlier this year?  We covered the story, if you need a reminder of what happened.

Here is the full presentation by Kalyanpur. (Slides were not made available to the general public):

Following this presentation, our own Jennifer Zaino caught up with Kalyanpur for this interview.
