Abstract: Systems and methods are described relating to detecting an indication of at least one attribute of an individual; accepting sensor data about the individual; and presenting a set of health care options at least partially based on the detecting an indication of at least one attribute of the individual and the accepting sensor data about the individual.

Abstract: The claimed subject matter relates to architectures that can construct a hierarchical set of decryption keys for facilitating user-controlled encrypted data storage with diverse accessibility and hosting of that encrypted data. In particular, a root key can be employed to derive a hierarchical set of decryption keys and a corresponding hierarchical set of encryption keys. Each key derived can conform to a hierarchy associated with encrypted data of the user, and the decryption capabilities of the decryption keys can be configured based upon a location or assignment of the decryption key within the hierarchy. The cryptographic methods can be joined with a policy language that specifies sets of keys for capturing preferences about patterns of sharing. These policies about sharing can themselves require keys for access and the policies can provide additional keys for other aspects of policy and or base-level accesses.

Abstract: A semantic query may refer to a logical rule, where the rule is defined in terms of constituent expressions. In order to execute the semantic query efficiently, occurrences of the rule may be expanded by replacing the rule with its constituent expressions. Expansion may be performed repeatedly, until only grounded expressions remain. Expressions are grounded when they refer to tables or views that are represented in an underlying database. Once the rule has been reduced to grounded expressions, the semantic query processor may formulate a relational query in terms of the grounded expressions. If the relational query takes into account the various grounded expressions to which the rule reduces, then the portion of the semantic query that refers to the rule may be processed without an excessive number of round trips to the relational database.

Abstract: In one example, information may be stored in a relational database. The information in the database may define a graph, in the sense that the information may define a set of entities and relations between the entities. A user may want to query the information using a graph-based query language. A graph query engine may receive the query, and may convert the query into a relational query language, for execution by the relational database. The relational database may calculate views of the underlying tables. Each view corresponds to a particular relation, and the rows in each view are pairs of entities to which the relation applies. Since the views correspond very closely to the specification of a graph, the graph-based query may be translated into a relational query that performs relational algebraic operations on the views in order to answer the graph-based query.
