Abstract: Systems and methods for multilingual keyword generation for low-resource language passages are disclosed. For example, high-resource language passages describing items in a catalog or other such passages may include numerous keywords for classifying and searching for the item while a low-resource language description of the item may not include the same rich keyword environment due to lower usage and traffic in the low-resource language. The systems and methods herein provide for leveraging the high-resource language through a multilingual natural language processing algorithm to identify similar passages across language barriers and identify keywords in the high-resource language for input into a decoder to generate keywords in the low-resource language.

Abstract: Devices and techniques are generally described for per-query prediction of shard relevance for search. In some examples, a search system may receive a first search query. A first score may be determined for a first database partition, the first score indicating a relevancy of the first search query to first data stored by the first database partition. Similarly, a second score may be determined for a second database partition, the second score indicating a relevancy of the first search query to second data stored by the second database partition. A determination may be made that the first search query is related to the first data stored by the first database partition. A determination may be made, based at least in part on the second score, that the first search query is unrelated to the second data stored by the second database partition.
