A distributed messaging platform may employ a trial system to provide a micro-randomized trial by identifying, over an electronic network, a plurality of user devices associated with a plurality of subjects; and at each of a plurality of intervals, and assigning the subjects into a respective distribution over a plurality of cohorts, such that the subjects are re-assigned at each fixed interval. The trial system may further perform operations that include, for each cohort, causing a respective subset of the user devices associated with subjects assigned to the cohort to output a respective treatment, the treatment for each cohort being different from each other; and collecting, from the user devices, response data of the subjects; such that, as the subjects are re-assigned to different cohorts across the different intervals, the user devices output different treatments corresponding to the different cohorts.

Systems and methods for providing a distributed platform with micro-randomized trials

Systems and methods for improved spelling checking are disclosed. A method includes receiving a search query from a user device and determining that the search query does not exist in a data store that stores (a) a corpus of correctly spelled words or (b) forced correction mapping data. The method further includes, in response to the determining, determining a plurality of suggested search queries generated by a plurality of respective spell corrector models, selecting a suggested search query determined using a spell corrector model from the plurality of spell corrector models based on at least one of a frequency of the suggested search query in historical search data or a weightage associated with the spell corrector model, and causing the suggested search query to be displayed on the user device.

Systems and methods for improved spell check

Various embodiments of the present disclosure provide computer interpretation techniques for implementing a query resolution process to improve upon traditional search resolutions within a search domain. The techniques may include generating a plurality of interaction embeddings for a plurality of textual descriptions corresponding to a plurality of interaction codes identified within an interaction dataset and a plurality of taxonomy embeddings for a plurality of taxonomy categories identified within a taxonomy dataset. The techniques may include generating similarity scores for a plurality of description-category pairs based on a comparison between the plurality of interaction embeddings and the plurality of taxonomy embeddings. The techniques may include generating an enhanced taxonomy by augmenting one or more of the plurality of taxonomy categories with one or more of the plurality of textual descriptions based on the similarity scores and initiating, using the enhanced taxonomy, the performance of a query resolution operation.
