Recommendations for media assets based on product similarities are provided. In some embodiments, a recommendation can be determined using asset-to-asset similarity information that can be obtained by mapping media assets to products and further mapping products to media assets based at least on the prior mapping. In addition, product similarity information can be leveraged to generate groups of media assets for different categories of similarity present in the product similarity information. Such groups can be identified, for example, by using the mapped products to media assets as applied to the different categories. Further a diverse arrangement of media assets can be generated by selecting media assets from the groups according to a defined selection rule.

Process and machine for media determination using product information

A document analysis module analyzes electronic media items and identifies regions and region types for the electronic media items. The document analysis module may use rules, typographical feature sets, and cluster analysis to identify regions and region types. The document analysis module may also receive user input and may use the user input to identify regions and region types. The document analysis module may further use template pages to identify regions and region types.

Document analysis for region classification

A content validation module receives an electronic media item in a first format. The content validation module may determine whether the electronic media item will contain errors when the electronic media item is converted to a second format. The content validation module may also obtain an error metric for the electronic media item and may refrain from converting the electronic media item to the second format if the error metric exceeds an error threshold.

Validating document content prior to format conversion based on a calculated threshold as a function of document size

In some implementations, content of a content item may be presented on an electronic device and a portion of the content item may be selected to be hidden from presentation. The electronic device may hide the selected portion of the content during presentation of the content. Further, selection information identifying at least the location of the selected portion of the content item may be communicated over a network to a computing device to enable synchronization of the hidden content with other instances of the content item on other devices of the user. In some examples, the user may select one or more chapters of the content item to be hidden by selecting one or more chapter identifiers in a table of contents of the content item. Hidden content may include text, images, audio and/or video content, depending on the type of content item that is accessed.
