Abstract: In an example method, a system accesses a plurality of data vectors representing a plurality of text segments; clusters the plurality of data vectors into one or more clusters; determines semantic topic of each of the one or more clusters; generates a data structure representing the semantic topic of each of the one or more clusters; and stores the data structure. Determining the semantic topic of a cluster includes: parsing fields of the data vectors of the cluster, determining a first word representing the cluster, determining a first value representing a frequency of the first word in a training data set, comparing the first value to a threshold value. Responsive to determining that the first value is less than the threshold value, the first word is identified as a semantic topic of the cluster.

Abstract: A networking manager of an extension server of a virtualized computing service detects that a data link layer frame has been obtained at the extension server. The networking manager delivers at least a portion of contents of the frame to a compute instance running at the extension server in response to determining that a destination media access control (MAC) address of the frame matches a MAC address of a local-premise-access virtual network interface attached to the compute instance. The local-premise-access virtual network interface is not assigned an Internet Protocol (IP) address from a range of IP addresses managed by the virtualized computing service.
