Abstract: A system is disclosed for evaluating diagnostic effectiveness of one or more diagnostic tests or additional findings from a set of known findings as to a patient. The system includes a computing device containing a software application which is used by a healthcare provider to review the patient's medical history and enter findings as to the patient's condition or symptoms, a system storing a validated probabilistic health model including a database of medical knowledge informed from aggregated electronic medical records or other sources of medical knowledge; and a medical knowledge-based inference engine operating on the patient's medical history and findings and the validated probabilistic health model. The engine determines a set of the most probable diseases of the patient, suggests a set of one or more tests or additional findings that differentiate the set of most probable diseases, and generates indicia indicating diagnostic effectiveness or relevancy of the one or more tests or additional findings.

Abstract: A system, a machine-readable storage medium storing instructions, and a computer-implemented method are described herein to a Discussion Relevance Engine that filters a plurality of discussions in a social network to identify a discussion pool. The Discussion Relevance Engine identifies a plurality of eligible discussions in the discussion pool, wherein each eligible discussion corresponds to a respective social network member group to which a target member account has previously subscribed. The Discussion Relevance Engine calculates, for each eligible discussion, a relevance score predictive of a relevance of the eligible discussion to the target member account. The Discussion Relevance Engine recommends at least one of the eligible discussions to the target member account based at least in part on the calculated relevance scores.

Abstract: A system, a machine-readable storage medium storing instructions, and a computer-implemented method are described herein to a Group Relevance Engine that generates, for a group in a social network, an aggregate group feature based on a common attribute shared amongst member accounts currently subscribed to the group. The Group Relevance Engine identifies an account feature corresponding to the common attribute in a profile of a target member account. The Group Relevance calculates a relevance score based at least on a match between the aggregate group feature and the account feature. The Group Relevance determines whether to recommend the group to the target member account based at least on the relevance score.

Abstract: A system, a machine-readable storage medium storing instructions, and a computer-implemented method are directed to a Digest Engine that identifies a feature(s) that is predictive of relevance, to a target member account in a professional social network, of content from a member group(s) to which the target member account is subscribed. Based on the feature(s), the Digest Engine determines a portion(s) of relevant content created amongst respective member accounts subscribed to the member group(s). The Digest Engine generates a persistent message providing access to the portion(s) of relevant content. The Digest Engine sends the persistent message to the target member account.

Abstract: A method and system are disclosed for browsing an electronic hierarchical product catalog. The catalog is organized as a tree data structure with each node corresponding to an item category, an item sub-category, or an attribute that describes characteristics of items in a category. Such attributes may be used as filters for searching for an item or item category. The catalog tree is a collection of linked independent sub-trees including category and attribute sub-trees. The sub-trees allow navigation of the catalog tree via links between various nodes. The sub-trees may be linked to multiple other sub-trees, providing easy navigation for users and simplifying the addition of new sub-categories and attributes to the catalog tree, for service providers. The use of linked sub-trees also allows attributes set by the user in a previous search to be used in a subsequent search for a similar item.
