Abstract: Embodiments relate to an intelligent computer platform to build a federated learning framework including creating a hierarchy of machine learning models (MLMs). The hierarchy of MLMs has a primary MLM in a primary layer. Training the primary MLM includes capturing contributing model updates across at least one communication channel. A secondary MLM is created and logically positioned in a secondary layer of the hierarchy. The secondary MLM is operatively coupled to the primary MLM across the at least one communication channel. The created secondary MLM is initialized, including cloning weights and framework of the primary MLM into the secondary MLM, and populated with secondary data. The populated data has model updates local to the created secondary MLM. The secondary MLM is logically stored local to the secondary layer, and limits access to the secondary MLM to the secondary layer.

Abstract: Provided are a computer program product, system, and method for generation of tasks and retraining machine learning modules to generate tasks based on feedback for the generated tasks. A machine learning module processes an input text message sent in the communication channel to output task information including an intended action and a set of associated users. A task message is generated including the output task information of a task to perform. The task message is sent to a user interface panel in a user computer. Feedback is received from the user computer on the output task information in the task message. The machine learning module is retrained to output task information from the input text message based on the feedback to reinforce likelihood correct task information is outputted and reinforce lower likelihood incorrect task information is outputted.

Abstract: Using a natural language analysis, a current message is classified into a current message class, the current message being a portion of an interaction in narrative text form. Using a trained message class prediction model, a probability of a previous message class having resulted in the current message class is determined. A previous message is extracted from the interaction using the probability, the previous message being a portion of the interaction occurring prior to the current message, the previous message being classified into the previous message class.

Abstract: A method, system and computer program product for improving understanding of comments on collections of data. A social media stream is monitored for comments to a container (e.g., photo album) and elements within the container (e.g., photographs). These comments are stored in a data structure along with an identification of the container or element of the container upon which the comments are directed. In response to a user selecting to view comments to an element within the container or the container itself, the data structure is searched for the comments to the selected element or container. Images of the container are then displayed in a fliptych manner, where the selected element or container is displayed in the center section of the fliptych. A list of comments is displayed in a comments section below the fliptych, where the list of comments includes highlighted comments directed to the selected element or container.

Abstract: Using a natural language analysis, a current message is classified into a current message class, the current message being a portion of an interaction in narrative text form. For the interaction using a state prediction model, an interaction outcome corresponding to the current message class is forecasted, the forecasting comprising computing a probability that the current message class will result in a successful message class. Using the state prediction model, a set of next message classes and a set of predicted interaction outcomes are determined, each message in the set of next message classes corresponding to the current message class, each predicted interaction outcome in the set of predicted interaction outcomes corresponding to a next message class in the set of next message classes. According to the corresponding predicted interaction outcome, the set of next message classes is ranked.

Abstract: A method, a device and a computer program product for processing a segment are proposed. In the method, a property of at least one of a first segment and a second segment in a segment set is obtained. The segment set includes a plurality of segments belonging to at least one conversation. The second segment occurs after the first segment. A boundary feature of at least one of the first segment and the second segment is determined based on the property. The boundary feature indicates whether there is a boundary of a conversation after the first segment.

Abstract: Familiarity-based text classification framework selection is described. A list of participants in an electronic message thread is selected. For each pairing of participants, a familiarity score is determined based on a number of criteria. A familiarity model is formed based on multiple familiarity scores and a text classification framework for the electronic message thread is selected based on the familiarity model.

Abstract: Provided are techniques for finding content on computer networks. A search request having search terms is received. The search request is executed against an index to identify first search results, wherein the index comprises mappings of search terms to web sites and mappings of search terms to patterns. In response to determining that the search request failed based on first search results, an unknown search term in the search terms that does not exist in the index is found. The unknown search term is matched to a pattern of a similar search term using the mappings of search terms to patterns. A candidate web site is identified based on the matching. Additional content is requested from the candidate web site for the unknown search term to identify second search results comprising previously hidden content. The additional content is indexed.

Abstract: A method, system and computer program product for handling notifications. A notification system monitors content (e.g., photograph) followed by a user for updates on a communication system. If the notification system identifies updates to content out of the monitored content, then the notification system applies the policy for delivering notifications concerning the content followed by the user that was updated. The notification system registers to receive information about updates to the content followed by the user as well as new events on the communication system. In response to identifying updates to content related to the content followed by the user that was updated from the received information, a summary concerning the updates to the content followed by the user and the related content is then generated. A notification is then delivered to the user containing the generated summary in a manner consistent with the policy.

Abstract: Task-oriented messages are presented to a user in an interactive format for disposition. Natural language processing techniques parse task-oriented messages for individual tasks, such as assignments, information requests, and requests for approval or authorization. A user interface provides a recipient of a task-oriented message with selectable tasks for individual, or group, disposition, such as respond, defer, delegate, mark answered, and ignore. Recipients are notified if an incomplete response is generated, such as when an identified task is not dispositioned.
