•Open Sourced Technologies. We deploy aspects of our technology into the open source
community to help increase the speed at which the technology can mature. The combination of
open source and proprietary technologies used in our platforms allows us to quickly deploy our
products at scale. For example, Hadoop is an open source project used to batch compute data
for different features on our website based on our members’ data and traffic patterns. Hadoop
enables us to scale our calculations on an expanding set of data and to perform these
calculations more frequently.
•Search. Our proprietary search technology combines structured and free-form content to allow
users to search across numerous parameters. Our search is powered by our rich dataset based
on facets and keywords and is fundamentally personalized as all search requests use a
member’s network to influence relevance and ranking. Our search is real time, distributed and
multilingual and serves the needs of both members and enterprises and professional
organizations.
•Customized Content, Matching, Targeting and Recommendations. We have developed a
proprietary intelligence and recommendation engine for extracting professional insights by
utilizing our rich dataset. This engine enables us to provide our users with customized content
and recommendations. For example, based on a member’s profile, their second and third degree
connections, their viewing and clicking history, and a host of other criteria, our algorithms can
provide intelligence and recommendations around Talent Match, People You May Know, Groups
You May Like, Jobs You May Be Interested In, Sponsored Content or Companies You May Be
Interested In. Our targeting and recommendation technologies continue beyond just a member’s
profile by providing intelligence around similar profile views and similar job views.
•Ad Targeting Platform. We use a combination of traditional and proprietary ad targeting and
delivery technologies. The combination is optimized to work with our respective partners to
provide the optimal user experience. Our proprietary systems leverage our feature extraction,
information retrieval, and matching systems to provide the most relevant ads.
•Document Conversion Technologies. We use a combination of open source and proprietary
technologies to convert documents in various formats (e.g., pdf, doc, ppt) into HTML5, a
mark-up language for structuring and presenting content on the Internet, so that the document
can be displayed on LinkedIn.com and Slideshare.net, and embedded throughout the Internet.
•Service Infrastructure. We have invested and are continuing to invest in updating our online
applications to our new service infrastructure, which we believe will improve developer
productivity, agility and operability, and accelerate our mobile strategy.
•Experimentation Platform. We have developed a testing platform that allows us to evaluate
different options for rendering an experience to our members. As a test runs, this platform
provides an in-depth perspective on how the test impacts our metrics. This proprietary
technology allows us to better evaluate potential changes in our products.
Operations
We have developed our website and related infrastructure with the goal of maximizing the
availability of our platform to our members, enterprises and professional organizations. Our website and
related infrastructure are hosted on a network located in multiple third-party facilities, and we lease
data center facilities in various locations.
Intellectual Property
We protect our intellectual property rights by relying on various laws and rights in the United States
and other countries, as well as contractual restrictions.
