Key Questions Answered
How does Facebook improve the accuracy of the WURFL database?
Facebook enhances the WURFL database by crowdsourcing information directly from users and conducting programmatic experiments to detect device capabilities. This approach allows them to gather input from millions of users, improving the accuracy of capability entries like screen size and AJAX support.
What challenges does WURFL face in keeping up with mobile devices?
WURFL struggles to keep pace with the rapid innovation in mobile devices, as there are numerous emerging models. Facebook's crowdsourcing efforts aim to address this by collecting real-time data from users, thus augmenting WURFL's existing capabilities.
What methods does Facebook use to analyze survey data from users?
Facebook groups survey responses by WURFL device ID and applies point estimation algorithms to derive capability values. This iterative process continues until data within each subgroup is consistent, allowing for accurate capability mapping despite initial noise in the data.
How does Facebook contribute to the WURFL project?
Facebook collaborates with Luca Passani to integrate new findings from their crowdsourcing and automated detection efforts back into the WURFL project. This support aims to streamline the data integration process for broader community use.
