On behalf of Ciklum Digital, Ciklum is looking for a Senior Data Scientist to join the team on a full-time basis.

Project description:

Client is an audio-first entertainment studio and independent audiobook publisher that finances, develops, produces and distributes immersive audio content.

While making an audiobook isn’t cheap it is crucial to know whether the audio book is going to be popular and successful or not. Client is looking to develop a tool which can predict the success of an audiobook depending on the success of the related online print book, genre, past experience and other data sources.

The Proof of Concept delivered was designed to test and evaluate the ability to use data for analysis of titles and predict which titles will be successful as audio books. Technology choices were made for speed in proving these hypotheses and not necessarily for the purposes of scaling. Client requested to enhance the product and focus on building out capability and improving usability, thereby enhancing accuracy.

Current objectives for the project include enhancing Client’s existing predictive analytics platform (‘Brenda’) and development of a web-application for data visualization purposes.
