MusicGraph semantically connects over a billion facts according to a rich music ontology that can be leveraged by users as well as developers

MIAMI–(BUSINESS WIRE)–December 4, 2013–

Senzari® today announced MusicGraph, the world’s first knowledge engine for music, which will be available as a consumer app across most major mobile platforms, as well as a powerful “graph API” that can be leveraged by developers to enhance their applications with deep musical intelligence. MusicGraph contains over a billion facts that have been organized into a rich music ontology, which includes acoustical and lyrical features, detailed artist, album and song information, as well hundreds of other data points related user preferences.

“We are very excited to unveil MusicGraph, which constitutes over two years of our work,” explained Demian Bellumio, COO of Senzari. “It all started when we were looking for a music recommendation engine to license for our own music service, and we found the few market alternatives to be very limiting in terms of data and features – all meant to build a Pandora clone. But even more frustrating was the onerous licensing structure, whereby you not only need to give up part of your business, but also have no real visibility into what is going on under the hood,” added Bellumio.

MusicGraph leverages the latest and most advanced “graph computing” and “Big Data” technologies to create large, distributed graphs, which contain detailed information of over twenty million songs, and are connected to millions of individual albums and artists across all genres. The information includes proprietary data generated via feature extraction from the music, like tempo, chord progression, and key, as well as lyrical data, such as ‘bag-of-words’ and concept extractions derived from lyrics.

The consumer version of MusicGraph has first been launched on the Firefox OS platform in order to support Senzari partner, Mozilla in development of this initiative. MusicGraph puts the world’s music knowledge at the fingertips of all Firefox OS users. MusicGraph will be expanded to iOS, Android and Windows Mobile users in the coming weeks. With the app users will be able to ask the service very detailed questions about the music they love, for example: “Who are artists that are similar to Coldplay that were born in Manchester and are male?”

The MusicGraph API is available under a “developer” model, which is free of charge, as well as a commercial licensing model. There are three core components of the API: the playlist generator, graph search and data access. The playlist generator allows for the creation of playlists based on Senzari’s proprietary graph algorithms that can personalize and contextualize each recommendation based on a variety of signals. Furthermore, each song recommendation comes with “evidence” that details why the song was chosen, providing an unparalleled level transparency when compared to other solutions in the market. The graph search component allows developers to incorporate Senzari’s deep musical knowledge into their apps and search engines. And lastly, Senzari’s data access component provides a number of low-level features extracted from the songs that developers and scientists can leverage to optimize their own music analysis or to develop new novel algorithms on top of it.

“We are excited to see how the market responds to our approach, as such a level of data access has not been common in the music space,” commented Bill Hajjar, CEO of Senzari. “More importantly, we are pricing our API starting at $499 and increasing based on usage, which is at least ten times lower than market alternatives. This model allows our partners to clearly understand how their costs will scale, like they do with other components of their infrastructure, such as AWS and other cloud services.”
