A content generation service is described that generates content for electronic documents in different languages based upon templates. The templates may include paragraph templates composed of sentence types including sentence templates. The sentence templates may further include variables having corresponding attributes. Each of the paragraph templates, sentence templates, and attributes may be hierarchically organized. The content generation service may obtain data describing an item of interest, such as a travel item. The obtained data may further specify a document language, section and paragraph for which content is to be generated. Content is generated for variables in hierarchical order, with higher ranked paragraphs considered first. Within the highest ranked paragraph, a sentence type is selected and the variables within the highest ranked sentence template of the sentence type are considered. Sentence templates which contain attributes matched by the data obtained for the item of interest are added to the generated document.
