Abstract: Systems and methods for displaying dynamically changing content within scrollview class applications are described. In some example embodiments, an intermediate module fetches images from an underlying layer of a webview module, and provides the images to a scrollview module, which presents the images via a scrollable user interface on a computing device, such as a scrollable user interface within a game application presenting an online game via a user interface of a mobile device.

Abstract: Methods and apparatus for selecting advertisements to display to a user requesting a primary webpage is provided. Keywords related to the primary webpage are determined using internal information of the primary webpage and/or external information provided in neighboring webpages. The external information may include anchor text metadata of hyperlinks on neighboring webpages that link to the primary webpage or include the number of such hyperlinks having a same particular anchor text. Other internal and/or external information may be used to determine a list of keywords related to the primary webpage. One or more of keywords on the list are selected to represent the primary webpage according to one or more objectives. One or more advertisements are selected to be served to the user using the selected keywords. Machine learning techniques may be used to develop a model that automatedly determines keywords representing a webpage.
