  • Patent number: 7921129
    Abstract: At least one implementation described herein relates to evaluating queries structured according to a first format against one or more objects structured according to a second, different format without serializing the object. Typically, evaluating an XML (eXtensible Markup Language) query against a CLR (Common Language Runtime) object required serializing the CLR object and deriving an XML construct from the serialized data. The query is then be evaluated against the XML construct. In the described implementations, significant system resources are realized by creating an infoset model that maps properties of an object to an object infoset. The query is then evaluated using the infoset to locate object values and, thus, no serialization is required. Dynamically generated IL is used and re-used to efficiently perform subsequent evaluation steps on similar queries.

  • Patent number: 7899817
    Abstract: Embodiments herein prevent or mitigate attacks on inverse query engines by providing safe mode routines that allow for the acceptance of third party messages and/or query expressions, as well as prevent trusted sources from accidental attacks. The mitigations fall into two categories: compile-time and runtime. Compile-time mitigations prevent query expressions from being accepted and compiled that are susceptible to known attacks. For example, the complexity of query expressions may be limited to functions with linear runtimes; constant memory usage; or ones that do not create large strings. Further, language constructs for the criteria in the query expression may not allow for nested predicates complexities. Runtime mitigations, on the other hand, monitor the data size and processing lengths of messages against the various query expressions. If these runtime quotas are exceeded, an exception or other violation indication may be thrown (e.g., abort), deeming the evaluation as under attack.

  • Publication number: 20110040576
    Abstract: Medical records may be evaluated in order to assign condition codes to the records in a medical vocabulary. In one example, the medical vocabulary contains a list of codes (e.g., numeric codes) that correspond to specific conditions, where each code is associated with a concept description. Text from a medical record may be used to form a query, and the query may be evaluated against the concept descriptions to determine which code(s) match the query. A code may be selected based on how well the description associated with that code matches the query. The process of converting text from medical records into queries, and then comparing the query to concept descriptions in a medical vocabulary, may be used to automate the process of assigning formal medical codes to arbitrary text records.

  • Patent number: 7664728
    Abstract: Implementations described herein relate to evaluating multiple queries represented in an opcode tree having opcode nodes and branch nodes. Each opcode node comprises an opcode that is a part of an opcode block derived from compilation of a query, the opcode block consisting of a linear sequence of opcodes. Opcode nodes are arranged in the tree according to location of its corresponding opcode in the opcode block with opcodes that occur earlier in the opcode block being represented at a higher tree level than subsequent opcodes. Only one opcode node corresponds to a common opcode block segment that is included in multiple queries. Executing the opcode tree against an input evaluates each of the multiple queries represented in the opcode tree.

  • Patent number: 7644064
    Abstract: At least one implementation described herein relates to using multiple filter engines to optimize query processing. A filter engine comprises a general matcher and at least one optimized matcher, a matcher being a filter engine in its own right. When the filter engine receives an input, the input is analyzed to determine if it can be handled by the optimized matcher. While the general matcher is fully compliant with a query language, the optimized matcher only handles a subset of the query language. Therefore, inputs that can be processed in the optimized matcher are compared against fewer filters, making the filtering process more efficient. The filter engine may also process only a portion of an input in the optimized matcher and another portion of the input in the general matcher, which reduces processing overhead.

  • Patent number: 7627681
    Abstract: The present invention extends to methods, systems, and computer program products for relaying messages through firewalls. A message relay negotiates first communication parameters with relay components inside a firewall and (potentially different) second communication parameters with applications outside the firewall. The message relay receives a message from an outside application in accordance with the second negotiated parameters and maps an electronic address in the received message to an inside application. The message relay transforms the message and sends the transformed message over an established connection through the firewall to a relay component in accordance with the first negotiated parameters. The relay component receives the transformed message and transforms the transformed message back into the message. The relay component delivers the message to the inside application in accordance with the second negotiated parameters.
