Abstract: A document management system accesses a document signed by one or more parties. The document may indicate one or more events that the parties contracted to occur in relation to the time-based conditions. The document management system inputs the document to a machine-learned model configured to identify one or more time-based conditions indicated in the document. The document management system receives one or more time-based conditions from the machine-learned model. For each time-based condition, the document management system identifies a respective database that catalogs event information corresponding to the time-based condition. The document management system obtains the event information related to the time-based condition and determines whether the time-based condition has been met based on the event information. For each time-based condition that has not been met, the document management system transmits an alert to one or more of the parties.

Abstract: Methods, systems, apparatuses, and computer-readable storage mediums described herein are directed to determining and recommending an optimal compute resource configuration for a cloud-based resource (e.g., a server, a virtual machine, etc.) for migrating a customer to the cloud. The embodiments described herein utilize a statistically robust approach that makes recommendations that are more flexible (elastic) and account for the full distribution of the amount of resource usage. Such an approach is utilized to develop a personalized rank of relevant recommendations to a customer. To determine which compute resource configuration to recommend to the customer, the customer’s usage profile is matched to a set of customers that have already migrated to the cloud. The compute resource configuration that reaches the performance most similar to the performance of the configurations utilized by customers in the matched set is recommended to the user.
