Four years of Schema org Recent Progress and Looking Forward

Posted by Ramanathan Guha, Google Fellow

In 2011, we announced schema.org, a new initiative from Google, Bing and Yahoo! to create and support a common vocabulary for structured data markup on web pages. Since that time, schema.org has been a resource for webmasters looking to add markup to their pages so that search engines can use that data to index content better and surface it in new experiences like rich snippets, GMail, and the Google App.

Schema.org, which provides a growing vocabulary for describing various kinds of entity in terms of properties and relationships, has become increasingly important as the Web transitions to a multi-device, mobile-oriented world. We are now seeing schema.org being used on many millions of Web sites, defining data types and properties common across applications, platforms and products, in order to enhance the user experience by delivering the most relevant information they need, when they need it.

In Schema.org: Evolution of Structured Data on the Web, an overview article published this week on ACM, we report some key schema.org adoption metrics from a sample of 10 billion pages from a combination of the Google index and Web Data Commons. In this sample, 31.3% of pages have schema.org markup, up from 22% one year ago. Structured data markup is now a core part of the modern web.

The schema.org group at W3C is now amongst the largest active W3C communities, serving as a hub for diverse groups exploring schemas covering diverse topics such as sports, healthcare, e-commerce, food packaging, bibliography and digital archive management. Other companies, also make use of the same data to build different applications, and as new use cases arise further schemas are integrated via community discussion at W3C. Each of these topics in turn have subtle inter-relationships - for example schemas for food packaging, for flight reservations, for recipes and for restaurant menus, each have different approaches to describing food restrictions and allergies. Rather than try to force a common unified approach across these domains, schema.orgs evolution is pragmatic, driven by the combination of available Web data, and the likelihood of mainstream consuming applications.

Schema.org is also finding new kinds of uses. One exciting line of work is the use of schema.org marked up pages as training corpus for machine learning. John Foley, Michael Bendersky and Vanja Josifovski used schema.org data to build a system that can learn to recognize events that may be geographically local to a particular user. Other researchers are looking at using schema.org pages with similar markup, but in different languages, to automatically create parallel corpora for machine translation.

Four years after its launch, Schema.org is entering its next phase, with more of the vocabulary development taking place in a more distributed fashion, as extensions. As schema.org adoption has grown, a number groups with more specialized vocabularies have expressed interest in extending schema.org with their terms. Examples of this include real estate, product, finance, medical and bibliographic information. A number of extensions, for topics ranging from automobiles to product details, are already underway. In such a model, schema.org itself is just the core, providing a unifying vocabulary and congregation forum as necessary.

Moore’s Law Part 3 Possible extrapolations over the next 15 years and impact

This is the third entry of a series focused on Moore’s Law and its implications moving forward, edited from a White paper on Moore’s Law, written by Google University Relations Manager Michel Benard. This series quotes major sources about Moore’s Law and explores how they believe Moore’s Law will likely continue over the course of the next several years. We will also explore if there are fields other than digital electronics that either have an emerging Moores Law situation, or promises for such a Law that would drive their future performance.

More Moore
We examine data from the ITRS 2012 Overall Roadmap Technology Characteristics (ORTC 2012), and select notable interpolations; The chart below shows chip size trends up to the year 2026 along with the “Average Moore’s Law” line. Additionally, in the ORTC 2011 tables we find data on 3D chip layer increases (up to 128 layers), including costs. Finally, the ORTC 2011 index sheet estimates that the DRAM cost per bit at production will be ~0.002 microcents per bit by ~2025. From these sources we draw three More Moore (MM) extrapolations, that by the year 2025:

• 4Tb Flash multi-level cell (MLC) memory will be in production
• There will be ~100 billion transistors per microprocessing unit (MPU)
• 1TB RAM Memory will cost less than $100

More than Moore
It should be emphasized that “More than Moore” (MtM) technologies do not constitute an alternative or even a competitor to the digital trend as described by Moore’s Law. In fact, it is the heterogeneous integration of digital and non-digital functionalities into compact systems that will be the key driver for a wide variety of application fields. Whereas MM may be viewed as the brain of an intelligent compact system, MtM refers to its capabilities to interact with the outside world and the users.

As such, functional diversification may be regarded as a complement of digital signal and data processing in a product. This includes the interaction with the outside world through sensors and actuators and the subsystem for powering the product, implying analog and mixed signal processing, the incorporation of passive and/or high-voltage components, micro-mechanical devices enabling biological functionalities, and more. While MtM looks very promising for a variety of diversification topics, the ITRS study does not give figures from which “solid” extrapolations can be made. However, we can make safe/not so safe bets going towards 2025, and examine what these extrapolations mean in terms of the user.

Today we have a 1TB hard disk drives (HDD) for $100, but the access speed to data on the disk does not allow to take full advantage of this data in a fully interactive, or even practical, way. More importantly, the size and construction of HDD does not allow for their incorporation into mobile devices, Solid state drives (SSD), in comparison, have similar data transfer rates (~1Gb/s), latencies typically 100 times less than HDD, and have a significantly smaller form factor with no moving parts. The promise of offering several TB of flash memory, cost effectively by 2025, in a device carried along during the day (e.g. smartphone, watch, clothing, etc.) represents a paradigm shift with regard of today’s situation; it will empower the user by moving him/her from an environment where local data needs to be refreshed frequently (as with augmented reality applications) to a new environment where full contextual data will be available locally and refreshed only when critically needed.

If data is pre-loaded in the order of magnitude of TBs, one will be able to get a complete contextual data set loaded before an action or a movement, and the device will dispatch its local intelligence to the user during the progress of the action, regardless of network availability or performance. This opens up the possibility of combining local 3D models and remote inputs, allowing applications like 3D conferencing to become available. The development and use of 3D avatars could even facilitate many social interaction models. To benefit from such applications the use of personal devices such as Google Glass may become pervasive, allowing users to navigate 3D scenes and environments naturally, as well as facilitating 3D conferencing and their “social” interactions.

The opportunities for more discourse on the impact and future of Moore’s Law on CS and other disciplines are abundant, and can be continued with your comments on the Research at Google Google+ page. Please join, and share your thoughts.

2013 Google PhD Fellowships 5 Years of Supporting the Future of Computer Science

Posted by Michael Rennaker, Google University Relations

We are extremely excited to announce the 2013 Global Google PhD Fellows. From all around the globe, these 39 PhD students represent the fifth class in the program’s history, a select group recognized by Google researchers and their institutions as some of the most promising young academics in the world. As we welcome the newest class of PhD Fellows, we take a look back at the program’s roots and hear from two past recipients.

In 2009, Google launched its PhD Fellowship Program, created to recognize and support outstanding graduate students pursuing work in computer science, related disciplines or promising research areas. In its inaugural year, 13 United States PhD students were awarded fellowships, drawn from an extremely competitive pool of applicants. The global program now covers Europe, China, India and Australia and continues to draw some of the best young researchers, reflecting Google’s commitment to building strong relations with the academic community.

Among those first recipients of the fellowship award are 2009 PhD Fellow Roxana Geambasu, Visiting Professor in the Computer Science Department at Columbia University, and 2010 European Doctoral Fellow Roland Angst, Visiting Assistant Professor at Stanford University and affiliated with the Max Planck Center for Visual Computing and Communication. As early recipients of the award, Roxana and Roland reflect on the impact that the Google Fellowship program had on their careers.

For Roxana, the fellowship provided the tools and connections that helped lay the foundation for her academic career. She believes industrial fellowship programs are very important, as they give students an opportunity to interact more closely with industry.

“Beyond the financial support, I think that the fellowship impacted my career in many important ways. First, the Google fellowships are regarded as highly competitive, so receiving the award was probably a big plus on my resume when I was interviewing for faculty positions.”

“Second, the award yielded a mentor within Google, Brad Chen, with whom Ive kept in touch ever since, as well as opportunities to visit the campus, deliver talks and meet Google engineers. Brad and I continue to meet at conferences and discuss my work, his work and (of late) the work of my students; it’s through that relationship I’m exposed to new people from Google and gain valuable advice about faculty award opportunities.”

Roland Angst credits the award with the ability to lighten his teaching load and instead focus on his research, which ultimately prepared him for his future academic career. Like Roxanna, Roland states that the fellowship also gave him the opportunity to establish connections with people working in related topics in industry.

“In my view, programs such as the Google Fellowship Awards represent an important and integral link between industry and universities. Firstly, such programs increase the awareness in the academic world for relevant problems in industry. Secondly, these programs allow the IT industry to express their gratitude to the educational services provided by the universities on which the IT industry heavily relies on."

We welcome the latest recipients of the Global Google PhD Fellowships for 2013 with great excitement and high expectations. Recognized for their incredible innovation, creativity and leadership, we are very happy to support these excellent PhD students and offer our sincere congratulations.

BASIC is 50 years old

Dartmouth University has announced that: "At 4 a.m. on May 1, 1964, in the basement of College Hall, Professor John Kemeny and a student programmer simultaneously typed RUN on neighboring terminals. When they both got back correct answers to their simple programs, time-sharing and BASIC were born." They created a whole website, BASIC at 50, to support this anniversary and events to support it. If youre a computing purist you probably despise BASIC, but you cant deny its influence - I first programmed using BASIC on a BBC Micro computer. However, one of my older colleagues believes the history of BASIC is not as simple as Dartmouth makes out saying "Dartmouth always had a good press office."

Revolution The First 2000 Years of Computing Exhibit Opens at the Computer History Museum

Whether it be art museums, history museums, museums that focus on a specific event in history or some other kind, people love going to museums. However, the majority of museums are generally more fun for the elderly, buffs of the certain genre or elementary school field trips. But there is one museum that caters to a different type of visitor, a more technological visitor, the Computer History Museum, and this week they have something new for all the tech junkies out there.

This week the Computer History Museum opened a $19 million, 25,000-square-foot expansion with a new signature exhibition known as "Revolution: The First 2000 Years of Computing." This new exhibit, after being in development for over six years, represents the most comprehensive physical and online exploration of computing history in the world. It spans everything from the abacus and slide rules all the way to robots, Pong and the Internet.

According to John Hollar, CEO of the museum located in Mountain View, California, "Many times, people coming to the museum have very basic questions: How did that computer on my desk get there? How did that phone Ive used for so long get smart? Its an exhibition thats primarily aimed at a non-technical audience, though theres a ton of great history and information for the technical audience as well."

The exhibition has been specifically designed to be accessible to visitors in a multitude of ways. This includes documents, video presentations, over 5,000 images and 1,100 artifacts in 19 galleries. The exhibit also features hands-on interactive stations that will demonstrate the principles of computing like being able to pick up a 24lb Osbourne computer or playing a game of Pong, Pacman or Spacewar.

There are many key artifacts in the exhibit including a 1956 IBM 305 computer as well as its 350 hard drive, the first commercially available machine of its type which practically took up an entire room and only held 5MB of data. Guests will also get to see the console of a 1950 Univac 1, the first household computer, a complete installation of the original IBM System/360, the dominate technology in mainframe computing for nearly 20 years and a Cray-1 supercomputer which was the worlds fastest from 1976 to 1982.

Guests will even get the opportunity to see "The Utah Teapot", the device graphics designer pioneer Martin Newell used as his 3D computer model at the University of Utah. The teapot became the standard reference for computer graphics and the more realistic the designers could make the teapot, the better their graphics engine was considered. The ENIAC, which was built during World War II and was the worlds first large-scale computer to run at electronic speed, is also on display.

"This is one of the greatest electronic computers ever invented," stated Holler. "Weve made this a very human story. Weve tried to talk about not just what happened, but what mattered in history. What mattered often boils down to the people who were the great innovators and the problems they were trying to solve, and so much of the exhibit is devoted to those important stories."

The ceremonial opening, which took place yesterday, contained a number of technological legends like Apple co-founder and engineer Steve Wozniak, computer programming pioneer Donald Knuth, video game inventors Al Alcorn and Steve Russell and IBMs first female fellow Fran Allen. The galleries of the exhibit will have many legends of the computing world speak as part of a series entitled "Revolutionaries".

Guest can also partake of an oral history program with over 40 interactive stations featuring the legends of computing. The stations will contain archived interviews with pioneers like Chuck Thacker from Xeroxs Palo Alto Research Center and John Atanasoff who built the first digital computer in 1939. Holler added, "We often say, wouldnt it have been great to have been able to talk to Michelangelo as he painted the Sistine Chapel? We can do that."

The exhibit is open now and is sure to be the highlight of any computer or tech lovers trip to the museum. If you love technology, history, computers or all of the above, then this is one place you have to visit before you die. Put it on your bucket list or tattoo it to the inside of your eyelids. Do whatever it takes to remember to go and see this exhibit.
