This Is Like is an online mnemonic network that helps you retain and share your knowledge through notating its relations. It was initiated in 2007 by Dmitry Paranyushkin with the support of Nodus Labs and went live in 2009.
 
This Is Like is an open system, which allows anyone to add content entities and make connections between them.
 
For example, one can start with adding their favorite venue in Berlin and connecting it to similar venues in New York. This way someone who’s traveling from NY to Berlin can quickly discover their scene quickly and easily.

A more sophisticated way to use the system is to notate one’s research. One can enter a certain concept and create relationships between this and other concepts, describing how they are related. This way it’s possible to keep track of the material and to represent it in a more interconnected way. This Is Like allows one to have instant access to the whole history of research and share it with others.
 
Finally, This Is Like can also be used to provide a more holistic way of navigating through website content. A user can quickly view how an article she is reading relates to the other articles on the website and navigate to related content. The difference from automated content recommender systems is that these relations are curated by the editors, thus providing a more quality way to represent interconnectedness of material within a certain context.

The actual website www.thisislike.com is a backend, which can be used to manually edit and view content. The software has an API, which allows remote access to the database and content for use in external applications. There is also a WordPress plugin and widget that enables easy use and integration of ThisIsLike system into blogs. This blog is an example of how ThisIsLike can be integrated into the platform, but you can also look at www.knnk.org or www.playberlin.com
