Abstract: Computerized systems are provided for detecting or receiving a sharing gesture in a communication group and responsively instantiating or updating one or more computer objects that include rich contextual data associated with the sharing gesture. These computer objects can be instantiated or updated based on one or more rules or policies. These computer objects or associated indications can be surfaced back to a user to give the user context regarding the shared resource. It can be determined whether a user has access to (or permission to access) such a computer object and/or an associated computer resource for presentation to the user.

Abstract: A numerical score for each of a plurality of skills is assigned for each current worker of a current team and for one or more candidate workers who are candidates for addition to the current team. Vector spaces of the numerical scores for each current worker and candidate worker team are constructed. From the vector space of skills for the or each current worker and the vector space of skills for the or each candidate worker, a measure of the overlap of the skills of the or each candidate worker with the skills of the or each worker of the current team is obtained. This thereby assesses the suitability of the or each candidate worker to join the current team of one or more workers.
