Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for providing an adaptive knowledge platform. In one or more aspects, a system can include a knowledge management component to acquire, classify and disseminate information of a dataset; a human-computer interaction component to visualize multiple perspectives of the dataset and to model user interactions with the multiple perspectives; and an adaptivity component to modify one or more of the multiple perspectives of the dataset based on a user-interaction model.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, provide visualizations of sentiment assessments derived from content published online. In one or more aspects, a method includes: obtaining sentiment scores and associated data, the sentiment scores assigned to entities based on emotional tone detected in obtained content; obtaining input defining a subset of the sentiment scores and associated data to present; and outputting a visualization corresponding to the subset of the sentiment scores and associated data. In addition, obtaining the input can include receiving a definition corresponding to company relationships used to filter the sentiment scores and associated data. The definition can include an indication of which relationship types indicate the company relationships, and parameters that govern filtering by the indicated company relationships.
