Aggregation (magazine)

Aggregation was a Canadian online magazine published between 2010 to 2012. Each issue collected together stories and trends from five contributors based on hyperlinks they'd discover on the web. It was one of the first Canadian publications designed exclusively for Apple's iPad.

Aggregation was conceived and published by Gary Campbell. It was released online, for free, on the 15th of the month for six consecutive months, from November 2010 to April 2011. After an eight-month hiatus, Campbell announced that a seventh issue was in the works. That issue was eventually published in August of 2012 while Campbell was living in New York City. There has been no indication whether more issues are forthcoming.

Each magazine cover featured a unique piece of interactive artwork by Campbell. The publication's design often took advantage of the multimedia nature of tablets by including touch-sensitive and video elements. Each issue's contributors were paid for their work through an honorarium to their charity of choice. Consequently, the publication raised several thousand dollars for Canadian charities far and wide. Other staff involved in the project included Jennifer Campbell, Laura Kathleen Maize and Rani Sheen.

Aggregation (linguistics)

Aggregation is a subtask of natural language generation, which involves merging syntactic constituents (such as sentences and phrases) together. Sometimes aggregation can be done at a conceptual level.

Examples

A simple example of syntactic aggregation is merging the two sentences John went to the shop and John bought an apple into the single sentence John went to the shop and bought an apple.

Syntactic aggregation can be much more complex than this. For example, aggregation can embed one of the constituents in the other; e.g., we can aggregate John went to the shop and The shop was closed into the sentence John went to the shop, which was closed.

From a pragmatic perspective, aggregating sentences together often suggests to the reader that these sentences are related to each other. If this is not the case, the reader may be confused. For example, someone who reads John went to the shop and bought an apple may infer that the apple was bought in the shop; if this is not the case, then these sentences should not be aggregated.
