20100161591 | SYSTEM AND METHOD OF GEO-BASED PREDICTION IN SEARCH RESULT SELECTION - A system and method is disclosed for determining a prediction measurement, or measure, using geo-spatial information which can be used to determine whether or not to include type of information in search results. The prediction measurement comprises a measure of the likelihood that an item of the type of information for which the prediction measure is determined will be selected, or clicked on, by a user, if the item of the type of information is included in the search result. Without limitation, one such information type is news. | 06-24-2010 |
20120150854 | Relevance Estimation using a Search Satisfaction Metric - The subject disclosure is directed towards using a satisfaction model's prediction as to whether a user was satisfied or dissatisfied in satisfying a search goal to help estimate the relevance of a URL/document that was returned and clicked by the user. The clickthrough data for a search goal session is processed by either a utility model or a despair model based on whether the satisfaction model indicated that the search goal session ended with the user satisfied or dissatisfied, respectively. The utility model distributes a utility value to each clicked URL, while the despair model distributes a despair value to each clicked URL. The utility value and despair value of each query-URL pair may be used as corresponding feature data for learning a search ranker. | 06-14-2012 |

20130191310 | PREDICTION MODEL REFINEMENT FOR INFORMATION RETRIEVAL SYSTEM - A learning system refines a prediction model that determines the effectiveness of a search engine in achieving a goal of a search. Search goal achievements are estimated for sequences of user actions in an unlabeled data set using the prediction model, which is based on a mixture model and values for parameters of the mixture model. The values of the parameters are redefined based at least on the search goal achievement estimates of the unlabeled set. The prediction model is stored in accordance with the mixture model and the redefined values. | 07-25-2013 |
20140067783 | IDENTIFYING DISSATISFACTION SEGMENTS IN CONNECTION WITH IMPROVING SEARCH ENGINE PERFORMANCE - Technologies pertaining to automatically identifying sets of query attribute values that are highly correlative with user dissatisfaction with a search engine are described. Dissatisfied queries are automatically identified through analysis of search logs, wherein a dissatisfied query is a query submitted to a search engine by a user, wherein the user was dissatisfied with search results provided by the search engine responsive to receipt of the query. Sets of query attribute values that are highly correlated with dissatisfied queries, and thus user dissatisfaction, are automatically identified based at least in part upon the identifying of the dissatisfied queries. Subsequent to identifying a set of query attribute values, a segment-specific ranker is learned that is configured to rank search results responsive to receipt of a query with the set of query attribute values, wherein the segment-specific ranker outperforms a general purpose ranker for queries having the set of query attribute values. | 03-06-2014 |

20100041149 | BIOREACTOR AND METHOD FOR GENERATING CARTILAGE TISSUE CONSTRUCTS - A bioreactor includes a housing and a support mechanism for suspending the housing above the bottom surface of a culture vessel. The housing includes a member having oppositely disposed first and second surfaces and an inner surface defining an opening. The opening extends between the first and second surfaces of the member. The bioreactor includes a gas and liquid permeable membrane having first and second surfaces attached to the second surface of the member. The first surface of the gas and liquid permeable membrane and the member define a culture space for growing or culturing cells. | 02-18-2010 |

20110313541 | METHODS FOR GENERATING CARTILAGE TISSUE - A hyaline-like, single layer cartilage tissue construct includes chondrogenic cells dispersed within an endogenously produced extracellular matrix. The single layer cartilage tissue construct has a glycosaminoglycan content substantially equal to the glycosaminoglycan content of native cartilage tissue. A method for generating a single layer cartilage tissue construct includes isolating a population of chondrogenic cells and then expanding the population of chondrogenic cells. Next, the population of chondrogenic cells is seeded into a bioreactor having a volume defined by oppositely disposed gas permeable membranes. The population of chondrogenic cells is then cultured in a serum-free culture medium for a time sufficient to permit the population of chondrogenic cells to differentiate and form the single layer cartilage tissue construct. | 12-22-2011 |

20100275138 | SYSTEM AND METHOD OF IDENTIFYING AND MEASURING RESPONSE TO USER INTERFACE DESIGN - In accordance with aspects disclosed herein, impact that a user interface design has on a user's experience is measured. User response to one or more user interface designs is measured. Two or more user interface designs can be compared based on user response to each design. A single user interface design can be evaluated based on one or more measures of user response to the user interface, or two or more user interface designs can be compared using one or more user response measures corresponding to the user interface designs. | 10-28-2010 |
