Abstract: A virtual assistant is configured to automatically identify tasks for a user by processing text from various applications of a unified communications platform (e.g., transcripts of conferences, voicemails, emails, and chat logs) to detect action items and infer associated action item data (e.g., task owner, location, and due date). For example, a virtual assistant system may be configured to utilize machine learning natural language understanding technology to extract action items from various input text to form a to-do list with due dates for the task owner. In some implementations, a two-tier machine learning model topology is used to identify action items in strings. The system may recognize named entities such as nouns, verbs, dates/times, locations of action item sentences. The output information may be displayed on a dashboard, in push notifications, or within other user interface aspects of a personal device, thus providing notification or task planning for personal assistance.

Abstract: A method for predicting changes in customer demand is provided. The method comprises collecting subscription data for a number of customers at specified time intervals, wherein each customer is subscribed to one of a number of defined bundles of services. Any changes in customer bundle subscriptions during a given time interval are determined along with metrics for defined customer tasks for subscribed services during the given time interval. Multimodal multi-task learning is used to simultaneously model both bundle subscription change events and time-to-event for each bundle subscription change. Using the modeling, types and timing of changes in customer bundle subscriptions are predicted based on customer service activities.

Abstract: Voicemail spam detection is performed based on content of voicemail messages. The content of an incoming voicemail message is compared to a spam template that includes a representation of a spam voicemail. Spam templates may be generated based on spam indications provided by users for voicemail messages they have received. User indications for sufficiently similar voicemail messages may be aggregated by maintaining a vote count for a spam template that reflects how many times a user has indicated a matching voicemail message is spam. A spam template may also include an occurrence count that reflects how many times voicemail messages matching a spam template have been detected in a telephony system. An incoming voicemail message may be compared to spam templates and, responsive to a match of content and/or a corresponding vote count or occurrence count meeting a condition, the voicemail message may be identified as spam.
