Free webinar: Putting all species in a graph database

Biology + Technology = OTOL

Neo4j screenshotOne of the developers of the Open Tree of Life demonstrates Thursday, during a free webinar, how graph databases are used to construct a tree of life. The lecture is organized by Neo Technology, which is the maker of Neo4j, an open-source database that is used for OTOL.

Stephen Smith, an ecology and evolutionary biology professor at the University of Michigan, is going to explain how Neo4j and other digital technologies are assisting in constructing the tree of life. Starting at 10:00 PDT (19:00 CEST), he will also discuss other aspects of the interface of biology with next generation technologies.

“Our project is building the tools with which scientists in the community can continually improve the tree of life as we gather new information. Neo4j allows us to not only store trees in their native graph form, but also allows us to map trees to the same structure, the graph. So in fact, we are facilitating the construction of the graph of life,” says Smith.

Neo4j approached the Open Tree of Life team to present a webinar because it is a project that utilizes the Neo4j graph database to represent the interconnectedness of biological data. The company considers the project a great example of how a graph database can better model the natural world.

The online lecture is intended for a broad audience including beginner computer programmers, advanced hackers, data scientists, natural scientists, and anyone interested in the cross-section of science and technology, especially data modeling. Over 150 people have already registered online.

Connecting millions of data points in a graph database

Creating ‘Facebook’ for species

Neo4j screenshotThe Open Tree of Life database is not just a list with about two million species. Information is added about their special characteristics and possible relationships with others as well. “It may become tens or hundreds of million pieces of data when we are all done.”

Stephen Smith, an evolutionary biology professor at the University of Michigan, is working together with the other researchers of the Open Tree of Life project to develop the programs and tools that will be used to construct the full tree of life. Scientists from all over the world can then synthesize all the information in the database.

“We are currently building the back-end of the Open Tree of Life. We need to create software that allows us to put all our information in a graph network, so that we can easily retrieve the information that researchers are specifically looking for.” (more…)
