20080221858 | Dynamic Online Multi-Parameter Optimization System and Method for Autonomic Computing Systems - An improved method and system for performing dynamic online multi-parameter optimization for autonomic computing systems are provided. With the method and system of the present invention, a simplex, i.e. a set of points in the parameter space that has been directly sampled, is maintained. The system's performance with regard to a particular utility value is measured for the particular setting of configuration parameters associated with each point in the simplex. A new sample point is determined using the geometric transformations of the simplex. The method and system provide mechanisms for limiting the size of the simplex that is generated through these geometric transformations so that the present invention may be implemented in noisy environments in which the same configuration settings may lead to different results with regard to the utility value. In addition, mechanisms are provided for resampling a current best point in the simplex to determine if the environment has changed. If a sufficiently different utility value is obtained from a previously sampled utility value for the point in the simplex, then rather than contracting, the simplex is expanded. If the difference between utility values is not sufficient enough, then contraction of the simplex is performed. In addition, in order to allow for both real and integer valued parameters in the simplex, a mechanism is provided by which invalid valued parameters that are generated by geometric transformations being performed on the simplex are mapped to a nearest valid value. Similarly, parameter values that violate constraints are mapped to values that satisfy constraints taking care that the dimensionality of the simplex is not reduced. | 09-11-2008 |
20080313737 | Stateful and Cross-Protocol Intrusion Detection for Voice Over IP - A method for detecting intrusions that employ messages of two or more protocols is disclosed. Such intrusions might occur in Voice over Internet Protocol (VoIP) systems, as well as in systems in which two or more protocols support some service other than VoIP. In the illustrative embodiment of the present invention, a stateful intrusion-detection system is capable of employing rules that have cross-protocol pre-conditions. The illustrative embodiment can use such rules to recognize a variety of VoIP-based intrusion attempts, such as call hijacking, BYE attacks, etc. In addition, the illustrative embodiment is capable of using such rules to recognize other kinds of intrusion attempts in which two or more protocols support a service other than VoIP. The illustrative embodiment also comprises a stateful firewall that is capable of employing rules with cross-protocol pre-conditions. | 12-18-2008 |
20100278325 | Annoying Telephone-Call Prediction and Prevention - A method for predicting whether a telephone call that is being set up will be considered annoying by the called party and, if so, for preventing it from being established. The illustrative embodiment predicts whether a telephone call will be considered annoying by the called party based on temporal characteristics of previous calls from the same caller. For example, when a called party receives an unwanted telephone solicitation, he or she will usually hang up within the first minute. If many telephone calls are made from the same caller, and all of these calls last under a minute, then it is reasonable to predict that future calls from this caller will be considered annoying. | 11-04-2010 |

20080255910 | Method and System for Adaptive Project Risk Management - A computer implemented method for improving project risk management based on (a) a quantitative analysis of risks affecting activities, i.e., the root factors leading to cost and time overruns on an activity by activity basis, and (b) an optimization of the resources allocation to each activity in the project plan, is employed to maximize the probability of completing projects on time and within-budget. The method can be employed prior to proceeding with one or more projects, but is also advantageous in that it is adaptive in the sense that more information can be learned during the course of a project about the risk factors present in the project, and this information is used to enable dynamically re-allocating resources to ensure a better outcome given an updated risk profile. Preferably, a Bayesian Belief Network (BBN) is used to capture how risk factors identified by project managers influence individual activity durations. | 10-16-2008 |

Preliminary types for the candidate answer are determined using first components to produce the preliminary types. Each of the first components produces a preliminary type using different methods. A first type-score representing a degree of match between the preliminary type and the question LAT is produced. Each preliminary type and each first type-score is evaluated using second components. Each of the second components produces a second score based on a combination of the first type-score and a measure of degree that the preliminary type matches the question LAT. The second components use different methods to produce the second score. A final score representing a degree of confidence that the candidate answer matches the question LAT is calculated based on the second score. | 09-18-2014 |
20150339299 | TYPE EVALUATION IN A QUESTION-ANSWERING SYSTEM - A system and method for automatically mapping LATs and candidate answers to multiple taxonomies without a need to merge these taxonomies. The method includes using a syntactic analysis of a corpus to extract all type instances of the LAT. The extracted instances are then mapped to a given taxonomy and clustered in a set of supertypes. Each supertype receives a score based on the coverage of LAT instances in the corpus. The method includes mapping the candidate answer to the same taxonomy to determine if the candidate answer is an instance of a significant supertype. Then the score of a candidate answer is obtained by aggregating or taking a maximum of the score of the matched significant supertypes. This score evaluates the type match between the LAT and candidate answer for a taxonomy. Multiple taxonomies can be used to increase the chance of LAT and candidate answer mapping. | 11-26-2015 |
