Abstract: Described technologies automatically evaluate contact information and other submitted textual content to identify suspect data. Different data validation technologies alone or in combination identify frivolous content such as profanity, gibberish, and mismatched meanings. These technologies may perform regular expression recognition, naïve Bayes or other probabilistic classifications, named entity recognition, and subsidiary functions such as data cleaning, gibberish generation, and model training. A predictor value indicates how likely it is that the submitted data is valid input, e.g., a valid person name or valid company name, as requested. A trained machine learning based content characterizer embodies rules for content characterization, including implicit rules produced by supervised machine learning. Some content characterizers identify suspect content other than range violations or data type violations, by identifying profanity or gibberish.

Abstract: Example method includes determining, by a network management device, a location of a client device in a wireless local area network (WLAN); identifying, by the network management device, a first region comprising the location of the client device, wherein an irregular boundary of the first region is arbitrarily defined on a floor plan based on a device sharing policy; determining, by the network management device, that the device sharing policy permits the client device to discover a network service provided by at least one network device; and selecting, by the network management device, the at least one network device to be presented as providing the network service available to the client device.

Abstract: A non-transitory computer readable medium includes instructions which, when executed by one or more hardware processors, causes performance of operations. The operations include receiving, by a network device from a first user device, a first message addressed to a second user device and identifying a first user role associated with the first user device and a second user role associated with the second user device. The operations further include determining whether a set of predefined user role relationships authorizes a communication between user devices having the first user role and user devices having the second user role. In response to determining that the set of predefined user role relationships do not authorize the communication between user devices having the first user role and user devices having the second user role, the operations refrain forwarding the first message from the first user device to the second user device.

Abstract: A non-transitory computer readable medium includes computer readable program code including instructions for snooping a message from a client device addressed to a particular IP address corresponding to a shared device; determining whether the client device has authorization to access the shared device; responsive to determining that the client device does not have authorization to access the shared device, refraining from forwarding the message to the particular IP address; and responsive to determining that the client device has authorization to access the shared device, forwarding the message to the particular IP address.

Abstract: The present disclosure discloses a method and network device for providing precise and custom location based service discovery application for wired and wireless devices. Specifically, a network device determines a location of a client device. The network device also identifies a first region including the location of the client device, and identifies at least one network device associated with the first region. Responsive at least to determining that the at least one network device is associated with the first region that comprises the location of the client device, the network device selects the at least one network device, from a set of network devices, for presenting as an available resource to the client device.

Abstract: The present disclosure discloses a method and system for a user to create favorite server lists for multiple services. Specifically, a network device receives a request for a particular service from a client device. Then, from a plurality of network devices that include functionality to provide the particular service, the network device selects a first subset of network devices based on stored data indicating that the first subset of network devices is associated with the client device. The network device further orders the plurality of network devices to obtain an ordered list such that the first subset of network devices is in a more preferred order than a second subset of network devices that are not included in the stored data. The network device next transmits, to the client device, information identifying the first subset of network devices as available devices for providing the particular service.
