194 Million Linked Open Data Bibliographic Work Descriptions Released by OCLC

OCLC WorldCat logoYesterday, Richard Wallis gave a peek into some exciting new developments in the OCLC’s Linked Open Data (LOD) efforts.  While these have not yet been formally announced by OCLC, they represent significant advancements in WorldCat LOD. Our reporting to date on LOD at WorldCat is here.

Most significantly, OCLC has now released 194 Million Linked Open Data Bibliographic Work descriptions. According to Wallis, “A Work is a high-level description of a resource, containing information such as author, name, descriptions, subjects etc., common to all editions of the work.” In his post, he uses the example of “Zen and the Art of Motorcycle Maintenance” as a Work.

Video: Shared Library Data at the ALA Annual 2013

Logo of the OCLCRegular readers of this blog may know that Linked Data and Semantic Web technologies are gaining significant traction in the worlds of Libraries, Archives, and Museums. Earlier this summer, Richard Wallis (Technology Evangelist) and Ted Fons (Executive Director, Data Services and WorldCat Quality) of the OCLC discussed and demonstrated how that organization in particular is sharing library data. This presentation was delivered at the Annual Conference of the American Libraries Association in Chicago.

The presentations by Fons and Wallis serve as good introductory pieces to practical Linked Data use, and the potential benefits of using Linked Data as a platform for knowledge management for large collections of data.  Wallis also discusses why OCLC chose to use schema.org as a vocabulary.

Ready, Set, Lightning! 5-Minute Talks at SemTechBiz — Part 2

During the recent Semantic Technology and Business Conference in San Francisco, a motley crew of expert presenters got up in front of a packed room, took a deep breath, and spoke passionately about the semantic projects nearest and dearest to their hearts while the unforgiving clock ticked their five precious minutes away. At the conference I shared highlights from some of those aptly named Lightning Sessions. Here are a few more snappy sessions that captivated the room that day:

Semantic Technology to Shed Light on Big Dark Data with Ben Zamanzadeh, DataPop

DataPop is a startup in the field of semantic advertising. The company seeks to create actionable insights for clients with semantics. As Ben put it, “Ad data is still dark data. Consumer actions are very hard to understand and even harder to predict.” The talk description explains DataPop’s approach: “DataPop’s Semantic Advertising Technology uses Machine Learned Semantic Models to build and analyze advertising campaigns that surpasses conventional advertising capabilities. Composite Semantic Data Models are used to translate Big piles of Data into meaningful entities, then Inference Engines transcribe information such that decisions and strategies can be formed. Semantic Methods has made it possible for us to explain the reasoning behind ‘why’ things happen.” Read more

Libraries: Time To Take Your Place On The Web Of Data

At The Semantic Technology and Business conference in San Francisco Monday, OCLC technology evangelist Richard Wallis broke the news that Content-negotiation was implemented for the publication of Linked Data for WorldCat resources. Last June, WorldCat.org began publishing Linked Data for its bibliographic treasure trove, a global catalog of more than 290 million library records and some 2 billion holdings, leveraging schema.org to describe the assets.

“Now you can use standard Linked Data technologies to bring back information in RDF/ XML, JSON, or Turtle,” Wallis said. Or triples. “People can start playing with this today.” As he writes in his blog discussing the news, they can manually specify their preferred serialization format to work with or display, or do it from within a program by specifying to the http protocol for the format to accept from accessing the URI.

“Two hundred ninety million records on the web of Linked Data is a pretty good chunk of stuff when you start talking content negotiation,” Wallis told the Semantic Web Blog.

Announcing the Winner of the Semantic Web.Com “Spotlight On Library Innovation”

One sector that has been very active in the adoption of Linked Data is that of libraries. In an effort to highlight this activity, SemanticWeb.com, supported by OCLC and LITA, put out a call last month for work that promoted or demonstrated the benefits of linked data for libraries.

In addition to being an active contributor, Kevin is responsible for the BIBFRAME website; has devised tools to view MARC records and the resulting BIBFRAME resources side-by-side; authored the first transformation code for MARC data to BIBFRAME resources; and is project manager for The Library of Congress’ Linked Data Service. Kevin also writes and presents frequently to promote BIBFRAME, ID.LOC.GOV, and educate fellow librarians on the possibilities of linked data.

Congratulations to Kevin!

If you want to learn more about BIBFRAME and the role Linked Data is playing in the world of libraries, join us at Semantic Technology & Business Conference, June 2-5 where Kevin’s colleague from the Library of Congress, Nate Trail, will deliver a lightning talk on BIBFRAME, and Richard Wallis of the OCLC will present From Record to Graph – Exposing a Legacy.

The Future of Libraries, Linked Data and Schema.Org Extensions

Yesterday The Semantic Link Podcast featured Karen Coyle, a consultant in library technology who’s consulted for esteemed institutions including the Library of Congress. Coyle discussed libraries’ long history with metadata, including with the MARC (machine-readable cataloging) format for nearly 50 years, and of sharing that metadata. That history helps explain why libraries, she said, are looking at semantic web technology – but also why changes to established processes are huge undertakings. “The move toward Linked Data will be the most significant change in library data in these two centuries,” she said, requiring the move from mainly textual data into using identifiers for things and data instead of strings.

Today, The Semantic Web Blog continues the discussion by sharing some perspectives on the topic from OCLC technology evangelist Richard Wallis. As noted in yesterday’s podcast, change has its challenges. “Getting the library community to get its head around Linked Data as a replacement for MARC … will be a bit of a challenge,” Wallis says. While more members of the library community are starting to “get” Linked Data, and what can be accomplished by extracting entities and linking between them, some still struggle with why change can’t just occur within the MARC format itself or its successor Resource Description and Access (RDA), that provides atomistic, machine-actionable data and machine-interpretable relationships. RDA, Wallis reminds us, took a decade from inception to publication and business model.

“The ramifications of turning into the Linked Data world are quite deep and meaningful but it will be a few years for that to be established in the library world,” Wallis says.

On Friday, February 8, a group of Semantic thought leaders from around the globe met with their host and colleague, Eric Franzon, for the latest installment of the Semantic Link, a monthly podcast covering the world of Semantic Technologies. This episode includes a discussion about libraries, an area that has seen a great deal of activity in the Linked Data space recently.

“The Linkers” were joined by a very special guest to discuss what’s been happening in the library world: Karen Coyle.

Karen Coyle Analyzes OCLC’s Top 50 Metadata Records

Karen Coyle recently analyzed a new release of OCLC metadata records. She writes, “OCLC recently released a file of 1.2 million metadata records for the most widely held items in its catalog. These are all items with 250 library holdings or more. I created a list on WorldCat of the top 50, mostly out of curiosity. I was quite surprised at the results, however. Here’s how it breaks down: 16 periodicals, with Time and Newsweek being numbers 1 and 2, respectively; 29 kid and YA books, four of which (and very high even in this small list) from the Diary of a Wimpy Kid series; 5 adult books.”

Coyle goes on, “The five adult books are: (1) McCullough, D. G. (1992). Truman. New York: Simon & Schuster. (2) Brown, D. (2003). The Da Vinci code: A novel. New York: Doubleday. (3) Johnson, S. (1998). Who moved my cheese?: An a-mazing way to deal with change in your work and in your life. New York: Putnam.  (4) Haley, A. (1976). Roots. Garden City, N.Y: Doubleday.  (5) Peters, T. J., & Waterman, R. H. (1982). In search of excellence: Lessons from America’s best-run companies. New York: Harper & Row. This small set gives me many ideas of things to investigate in the full set.”
