Patent number: 11138216Abstract: A unified visualization interface is disclosed. One example is a system including an association module, a multicasting module, a data sharing module, and a unified visualization interface. The association module associates an identified event in a first visualization system with a visualization function. The multicasting module stores event data related to the identified event and the associated visualization function in a shared data source, and multicasts the identified event to a second visualization system. The data sharing module associates the event data with characteristics of the first visualization system, and shares, in response to the multicast of the identified event, the shared data source with the second visualization system.Type: GrantFiled: February 20, 2015Date of Patent: October 5, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ming C Hao, Michael Hund, Nelson L Chang, Riddhiman Ghosh, Gregory William Cook, Kevin Smathers, Arun Kumar Paruchuri, Renato Keshet

Patent number: 10614094Abstract: A technique for visualizing topics includes depicting topic bubbles including pixels. In one example, selected topics are identified from records based on scoring candidate terms in the records according to a user-specified metric and a metric selected from among frequencies of occurrence of records pertaining to the respective candidate terms, and negativity of sentiment expressed with respect to the candidate terms in the records. A visualization is generated including bubbles representing topics, the bubbles including pixels representing corresponding records. A bubble has a shape dependent upon a number of records and a time interval represented by the bubble. Visual indicators are assigned to the pixels in a given bubble according to values of an attribute expressed in the corresponding records for the topic represented by the given bubble, resulting in the analysis of the selected topics being less time consuming and labor intensive.Type: GrantFiled: April 30, 2014Date of Patent: April 7, 2020Assignee: MICRO FOCUS LLCInventors: Ming C. Hao, Michael Hund, Christian Rohrdantz, Riddhiman Ghosh, Nelson L. Chang, Meichun Hsu, Daniel Keim
