| 20100241639 | APPARATUS AND METHODS FOR CONCEPT-CENTRIC INFORMATION EXTRACTION - Disclosed are methods and apparatus for extracting (or annotating) structured information from web content. Web content of interest from a particular domain is represented as one or more tree instances having a plurality of branching nodes that each correspond to a web object such that the tree instances correspond to one or more structured data instances. The particular domain is associated with domain knowledge that includes one or more presentation rulesets that each specifies a particular structure for a set of data instances, a domain-specific concept labeler, one or more specified properties of the web objects in the tree instances, and a concept schema that specifies a representation of the data to be extracted from the web content. A structured data instance that conforms to the concept schema is extracted from the one or more tree instances based on the domain knowledge for the particular domain. Extraction of the structured data instances is accomplished by (i) using the domain-specific concept labeler to annotate a subset of nodes of the tree instances; and (ii) using a locally adaptive concept annotator to extract the structured data instances based on the annotated segments and the local properties associated with such annotated segments. The extracted structured data instance is stored as structured output records in a database. | 09-23-2010 |

| 20080294495 | Methods of Processing and Segmenting Web Usage Information - A current behavioral targeting system is first tested using a suite of test data. The output of the test is one or more performance metrics. Next, newly proposed behavioral targeting system created. The newly proposed behavioral targeting system is then evaluated using both the existing source data and a new source data. The evaluation of the newly proposed behavioral targeting system produces one or more performance metrics of the same type earlier calculated. Finally, the two sets of performance metrics are compared. The performance metric difference represents the impact of the new source data. | 11-27-2008 |
| 20100076815 | STORAGE OPTIMIZATION FOR UPDATED USER BEHAVIORAL PROFILE SCORES - Scores are maintained usable by a behavioral targeting service for providing personalized content, such as advertisements. Event indications are processed, wherein the event indications being processed are indicative of user interaction generally with at least one online. It is determined, based at least in part on detected events (usable for scoring), scoring data indicative of user behavior relative to the at least one online service for each of a plurality of targeting categories. This includes updating the scoring data based on additional event indications being detected as being usable for generating scoring data for behavioral targeting. The updated scoring data is caused to be provided to the data store accessible to the behavioral targeting service when it has been determined that the updated scoring data will change the operation of the behavioral targeting service with respect to personalized content that would be served based on the updated scoring data. | 03-25-2010 |
| 20100077152 | PRIMARY-SECONDARY CACHING SCHEME TO ENSURE ROBUST PROCESSING TRANSITION DURING MIGRATION AND/OR FAILOVER - Scores are maintained usable by a behavioral targeting service. Each of a plurality of scoring engine partitions is provided events (first events) for at least one of the particular non-overlapping subsets of the users, and at least one particular scoring engine partition is also provided events (second events) for at least an additional one of said particular non-overlapping subsets of the users. The event indications are processed to determine updated scoring data indicative of behavior of the users represented by the detected events relative to the at least one online service and the updated scoring data are written to a persistent scoring engine storage. The particular scoring engine provides updated scores to the persistent scoring engine storage according to a first writeback caching scheme for updated scores determined from the first events and according to a second writeback caching scheme for updated scores determined from the second events. The time-to-live parameters are controlled for the first writeback caching scheme independently of controlling time-to-live parameters for the second writeback caching scheme. | 03-25-2010 |

A profile engine processes event indications that are both indicative of interaction by users generally with at least one online service and are specifically indicative of events usable for generating profile data for behavioral targeting to provide personalized content. It is determined which of a plurality of behavioral models to apply to an event indication based on a time associated with the event indication and time periods associated with the behavioral models. The determined behavioral model is applied to determine at least one updated profile. The behavioral targeting service determines which of the plurality of behavioral models to apply to the updated profile data based on a time associated with the updated profile, and processes the updated profile data provided by the profile engine according to the determined behavioral model and, based at least in part on the further processed updated profile data, causes personalized content to be provided in response to the request. | 04-01-2010 |

| 20090278726 | Method and Apparatus for Representing and Classifying Microwave Back-Projection Radar Signals - A moving object is classified by transmitting, by a linear array of transmit antenna elements, a microwave into a surveillance area. A scattered microwave backprojected from a moving object is received by a linear array of receive antenna elements. Features are extracted from the scattered microwave related to a spiral evolution of the scattered microwave. The moving object is then classified as one of a set of possible classes according to the extracted features, and an alarm signal can be generated indicating the selected class. | 11-12-2009 |

| 20090177443 | METHOD AND SYSTEM FOR DETECTING CHANGES IN SENSOR SAMPLE STREAMS - A method detects a change in a stream of samples acquired by a sensor. A stream of samples acquired by a sensor over time is stored sequentially in a buffer in which an oldest sample is discarded and a newest sample is stored when the buffer is full such that the buffer forms a window of samples sliding forward in time. For each new sample, the buffer is partitioned into all possible pairs of contiguous sub-windows of samples including a first sub-window and a second sub-window such that the newest sample is stored in the second sub-window of the pair. A difference is determined between the first and second sub-window of each pair of the contiguous sub-windows of samples, and a maximum difference is assigned as a merit score. A change in the stream of samples is signaled if the merit score is greater than a predetermine threshold. The change can be abrupt or gradual. | 07-09-2009 |

The displayed prices may include a last price, best offer and bid prices and depth of market prices. A cell is provided for each price and a color indicator for a price to be persisted is implemented, e.g., as a background coloring of the cells. Best offer and bid prices may be indicated by a first color, e.g., white, depth of market offer prices indicated by a second color or colors in one color family, e.g., green, and depth of market bid prices indicated by color or colors in another color family, e.g., red, with the particular color becoming more intense (e.g., darker) as the price worsens. | 11-03-2011 |
