Assignments of IoT device types

A method comprising:

• receiving, by a processor, data pertaining to a network interaction by an Internet of Things (IoT) device;
• extracting, by the processor, a set of features associated with the interaction from the received data;
• accessing, by the processor, a plurality of previously identified sets of features corresponding to other IoT devices, the plurality of previously identified sets of features being assigned with respective device types;
• determining, by the processor, whether the extracted set of features is similar to any of the previously identified sets of features within a predefined similarity threshold;
• and
• based on a determination that the extracted set of features does not meet the predefined similarity threshold with respect to any of the plurality of previously identified sets of features,
• querying, by the processor, a knowledge graph for identification of a cluster of features that includes at least some of the extracted set of characteristics, wherein the cluster of features is one of a plurality of clusters of features in the knowledge graph, and wherein each of the plurality of clusters of features includes a device type;
• and
• assigning, by the processor, the device type in the cluster of features that most closely meets the query as the device type of the device.

A non-transitory computer-readable medium on which is stored machine-readable instructions that when executed by a processor, cause the processor to:

• construct a table that includes rows of features, wherein each of the features in the rows of features corresponds to a feature of a communication over a network by an Internet of Things (IoT) device and an indication of a device type of the IoT device;
• construct a knowledge graph that includes clusters of features, each cluster of features including a plurality of nodes corresponding to an IoT device, wherein each of the plurality of nodes identifies a feature of a communication over the network by an IoT device, and wherein one of the features in each of the clusters of features is a device type assigned to the cluster of features;
• and
• for each of the clusters, interconnect features that have at least a predefined minimum weight with links, wherein the weights correspond to levels at which features are relevant to an identification of device types of the IoT devices.
