  • Systems and methods for homogeneous entity grouping
    Patent number: 10372743
    Abstract: Systems and methods are disclosed to identify entities that have a similar meaning, and may, in embodiments, be grouped into entity groups for knowledge base construction. In embodiments, the entity relations of similarity or non-similarity for an entity pair are predicted as a binary relationship. In embodiments, the prediction may be based upon similarity score between the entities and the entity features, which features are constructed using an entity feature or representation model. In embodiments, the prediction may be an iterative process involving minimum human checking and existing knowledge update. In embodiments, one or more entity groups are formed using graph search from the predicted entity pairs. In embodiments, a group centroid entity may be selected to represent each group based on one or more factors, such as its generality or popularity.

  • Integrating a calendaring system with a mashup page containing widgets to provide information regarding the calendared event
    Patent number: 10373121
    Abstract: A method, system and computer program product for integrating a calendaring system with a mashup page. A mashup server accesses the calendar data inputted by a user to create or edit an entry in a calendar application. The mashup server provides the user access to widgets to be included on a mashup page, where the widgets use the accessed calendar information so that the widgets provide information to the recipients of the calendared event. In this manner, the widgets provide information that normally would be accessible by the participants via links to a myriad of disjoint applications thereby negating the fractured experience of the participants. Upon finalizing the mashup page, the mashup page is saved as a Uniform Resource Location (URL) in the created/edited calendar entry. The mashup page is later transmitted by the mashup server to the recipients of the calendar entry.
