SEARCH DECONSTRUCTION, RECONSTRUCTION, AND ALLOCATION

摘要

A machine is configured to access a search phrase or other communicated phrase and deconstruct the accessed phrase into multiple subphrases. The machine performs an analysis of n-grams that occur within the sub-phrases, generates a set of potentially different sub-phrases from the ngrams, and selects which data source among multiple available video sources should be accessed for each generated sub-phrase in the generated set. For example, the machine may allocate each generated sub-phrase to a corresponding data source and cause the corresponding data source to execute a query based on its corresponding sub-phrase. Thus, the machine chooses from which data source to obtain partial search results that correspond to each subphrase generated based on the analyzed n-grams in the accessed phrase.
