Improving Google Patents with European Patent Office patents and the Prior Art Finder

At Google, we're constantly trying to make important collections of information more useful to the world. Since 2006, we’ve let people discover, search, and read United States patents online. Starting this week, you can do the same for the millions of ideas that have been submitted to the European Patent Office, such as this one.

Typically, patents are granted only if an invention is new and not obvious. To explain why an invention is new, inventors will usually cite prior art such as earlier patent applications or journal articles. Determining the novelty of a patent can be difficult, requiring a laborious search through many sources, and so we’ve built a Prior Art Finder to make this process easier. With a single click, it searches multiple sources for related content that existed at the time the patent was filed.

Patent pages now feature a “Find prior art” button that instantly pulls together information relevant to the patent application.

The Prior Art Finder identifies key phrases from the text of the patent, combines them into a search query, and displays relevant results from Google Patents, Google Scholar, Google Books, and the rest of the web. You’ll start to see the blue “Find prior art” button on individual patent pages starting today.

Our hope is that this tool will give patent searchers another way to discover information relevant to a patent application, supplementing the search techniques they use today. We’ll be refining and extending the Prior Art Finder as we develop a better understanding of how to analyze patent claims and how to integrate the results into the workflow of patent searchers.

These are small steps toward making this collection of important but complex documents better understood. Sometimes language can be a barrier to understanding, which is why earlier this year we released an update to Google Translate that incorporates the European Patent Office’s parallel patent texts, allowing the EPO to provide translation between English, French, German, Spanish, Italian, Portuguese, and Swedish, with more languages scheduled for the future. And with the help of the United States Patent & Trademark Office, we’ve continued to add to our repository of USPTO bulk data, making it easier for researchers and law firms to analyze the entire corpus of US patents. More to come!

Export of Office Outlook contacts to GMail

To import your Microsoft Office Outlook contacts to GMail or Google Apps, you need to export them first to a CSV file.

• In Outlook, go to the "File" tab in the ribbon menu, and click "Options" in the left sidebar.
• In the Outlook Options dialog, click on "Advanced" in the sidebar, and click the "Export" button. 
• In the first step of the Import and Export wizard, select "Export to a file", and click "Next".
• In the second step, select "Comma Separated Values (Windows)", and click "Next".
• In the third step, select your Contacts folder that you want to export (normally "Contacts"), and click "Next".
• In the fourth step, enter or select the filename, e.g. "contacts.csv".
• Click "Finish" to start the export.

When you import this file in GMail, and you are a member of a Windows Active Directory domain, the e-mail addresses are not imported.  Instead, the e-mail address field in GMail contains the "distinguished name" of your contact as known to your ActiveDirectory.  E.g. "cn=jsmith,ou=promotions,ou=marketing,dc=noam,dc=reskit,dc=com".
The real e-mail address is however included in the CSV file, as part of the column "E-mail Display Name", which contains the full name and the regular e-mail address between parentheses, but this column isn't used by the GMail import.

You could replace all E-Mail Addresses in the file using an Excel formula, or manually in a text-editor.
Or you can simply use this FxGqlC command to replace all e-mail address columns with the e-mail address taken from the display name:

select replaceregex($line, '\"/o=.*?\",\"EX\",(\".*?\((.*?)\)\")', '"$2","EX",$1') into [contacts2.csv] from [contacts.csv]

The same method can be used to replace national telephone numbers into an international format:
select replaceregex($line, '\+?(32\d{8,9})', '+$1') into [meucci3.csv] from [meucci2.csv]

You need to adopt the regular expression to a format appropriate for your contacts.

Import the resulting file in GMail, and that's it.

Teaching the World to Search

Posted by Maggie Johnson, Director of Education and University Relations

For two weeks in July, we ran Power Searching with Google, a MOOC (Massive Open Online Course) similar to those pioneered by Stanford and MIT. We blended this format with our social and communication tools to create a community learning experience around search. The course covered tips and tricks for Google Search, like using the search box as a calculator, or color filtering to find images.

The course had interactive activities to practice new skills and reinforce learning, and many opportunities to connect with other students using tools such as Google Groups, Moderator and Google+. Two of our search experts, Dan Russell and Matt Cutts, moderated Hangouts on Air, answering dozens of questions from students in the course. There were pre-, mid- and post-class assessments that students were required to pass to receive a certificate of completion. The course content is still available.

We had 155,000 students register for the course, from 196 countries. Of these, 29% of those who completed the first assessment passed the course and received a certificate. What was especially surprising was 96% of the students who completed the course liked the format and would be interested in taking other MOOCs.

This learning format is not new, as anyone who has worked in eLearning over the past 20 years knows. But what makes it different now is the large, global cohort of students who go through the class together. The discussion forums and Google+ streams were very active with students asking and answering questions, and providing additional ideas and content beyond what’s offered by the instructor. This learning interaction enabled by a massive “classroom”, is truly a new experience for students and teachers in an online environment.

Going forward, we will be offering Power Searching with Google again, so if you missed the first opportunity to get your certificate, you’ll have a second chance. Watch here for news about Power Searching as well as some educational ideas that we are exploring.

Speech Recognition and Deep Learning

Posted by Vincent Vanhoucke, Research Scientist, Speech Team

The New York Times recently published an article about Google’s large scale deep learning project, which learns to discover patterns in large datasets, including... cats on YouTube!

What’s the point of building a gigantic cat detector you might ask? When you combine large amounts of data, large-scale distributed computing and powerful machine learning algorithms, you can apply the technology to address a large variety of practical problems.

With the launch of the latest Android platform release, Jelly Bean, we’ve taken a significant step towards making that technology useful: when you speak to your Android phone, chances are, you are talking to a neural network trained to recognize your speech.

Using neural networks for speech recognition is nothing new: the first proofs of concept were developed in the late 1980s(1), and after what can only be described as a 20-year dry-spell, evidence that the technology could scale to modern computing resources has recently begun to emerge(2). What changed? Access to larger and larger databases of speech, advances in computing power, including GPUs and fast distributed computing clusters such as the Google Compute Engine, unveiled at Google I/O this year, and a better understanding of how to scale the algorithms to make them effective learners.

The research, which reduces the error rate by over 20%, will be presented(3) at a conference this September, but true to our philosophy of integrated research, we’re delighted to bring the bleeding edge to our users first.

Reflections on Digital Interactions: Thoughts from the 2012 NA Faculty Summit

Posted by Alfred Spector, Vice President of Research and Special Initiatives

Last week, we held our eighth annual North America Computer Science Faculty Summit at our headquarters in Mountain View. Over 100 leading faculty joined us from 65 universities located in North America, Asia Pacific and Latin America to attend the two-day Summit, which focused on new interactions in our increasingly digital world.

In my introductory remarks, I shared some themes that are shaping our research agenda. The first relates to the amazing scale of systems we now can contemplate. How can we get to computational clouds of, perhaps, a billion cores (or processing elements)? How can such clouds be efficient and manageable, and what will they be capable of? Google is actively working on most aspects of large scale systems, and we continue to look for opportunities to collaborate with our academic colleagues. I note that we announced a cloud-based program to support Education based on Google App Engine technology.

Another theme in my introduction was semantic understanding. With the introduction of our Knowledge Graph and other work, we are making great progress toward data-driven analysis of the meaning of information. Users, who provide a continual stream of subtle feedback, drive continuous improvement in the quality of our systems, whether about a celebrity, the meaning of a word in context, or a historical event. In addition, we have found that the combination of information from multiple sources helps us understand meaning more efficiently. When multiple signals are aggregated, particularly with different types of analysis, we have fewer errors and improved semantic understanding. Applying the “combination hypothesis,” makes systems more intelligent.

Finally, I talked about User Experience. Our field is developing ever more creative user interfaces (which both present information to users, and accept information from them), partially due to the revolution in mobile computing but also due in-part to the availability of large-scale processing in the cloud and deeper semantic understanding. There is no doubt that our interactions with computers will be vastly different 10 years from now, and they will be significantly more fluid, or natural.

This page lists the Googler and Faculty presentations at the summit.

One of the highest intensity sessions we had was the panel on online learning with Daphne Koller from Stanford/Coursera, and Peter Norvig and Bradley Horowitz from Google. While there is a long way to go, I am so pleased that academicians are now thinking seriously about how information technology can be used to make education more effective and efficient. The infrastructure and user-device building blocks are there, and I think the community can now quickly get creative and provide the experiences we want for our students. Certainly, our own recent experience with our online Power Searching Course shows that the baseline approach works, but it also illustrates how much more can be done.

I asked Elliot Solloway (University of Michigan) and Cathleen Norris (University of North Texas), two faculty attendees, to provide their perspective on the panel and they have posted their reflections on their blog.

The digital era is changing the human experience. The summit talks and sessions exemplified the new ways in which we interact with devices, each other, and the world around us, and revealed the vast potential for further innovation in this space. Events such as these keep ideas flowing and it’s immensely fun to be part of very broadly-based, computer science community.
