摘要： A collaborative filtering method for evaluating a group of items to aid in predicting utility of items for a particular user comprises assigning an item value of either known or missing to each item of the group of items, and applying a modification scheme to the item values of the missing items to assign a confidence value to each of the item values of the missing items to thereby generate a group of modified item values. The group of items having modified item values and the group known items are evaluated to generate a prediction of utility of items for a particular user.
摘要翻译：用于评估一组项目以帮助预测特定用户的项目的效用的协同过滤方法包括将已知或缺失的项目值分配给该组项目的每个项目，并将修改方案应用于项目值丢失的项目来为缺失项目的每个项目值分配置信度值，从而生成一组修改后的项目值。对具有修改项目值的项目组和组已知项目进行评估以产生用于特定用户的项目的效用的预测。

摘要： There is described a system and computer-implemented method for providing a recommendation based on a sparse pattern of data. An exemplary method comprises determining a likelihood that an item for which no user preference data is available will be preferred. The exemplary method also comprises determining a likelihood that an item for which user preference data is available for users other than a particular user will be preferred based on the likelihood that the item for which no user preference data is available will be preferred. The exemplary method additionally comprises predicting that an item for which no user preference data relative to the particular user is available will be preferred if the likelihood that the particular user will prefer the item exceeds a certain level.
摘要翻译：描述了一种用于基于稀疏数据模式提供推荐的系统和计算机实现的方法。一种示例性方法包括确定优选不具有用户偏好数据可用的项目的可能性。该示例性方法还包括基于不优选没有用户偏好数据的项目的可能性来确定用户偏好数据可用于除特定用户之外的用户可能优选的可能性。该示例性方法还包括如果特定用户更喜欢该项目的可能性超过一定水平，则预测相对于该特定用户没有用户偏好数据可用的项目将是优选的。

摘要： A system and method for providing personalized recommendations are disclosed herein. A system includes a processor and a software system executed by the processor. The software system provides a recommendation for an item. The recommendation is based on a comparison of a low-rank approximation of a domain matrix to a user profile. The user profile is based, in part, on the low-rank approximation of the domain matrix.

摘要： Systems, methods, and machine readable and executable instructions are provided for collaborative filtering. Collaborative filtering includes representing users and objects by rows and columns in a binary ratings matrix having a particular dimensional space. Unknown values in the binary ratings matrix are weighted with a weight matrix having the particular dimensional space. The binary ratings matrix and the weight matrix are hashed into a lower dimensional space by one of row and column. The hashed binary ratings matrix and the hashed weight matrix are low-rank approximated by alternating least squares. A result of the low-rank approximation for the one of row and column is updated using the binary ratings matrix and the weight matrix. A recommendation of one of the objects can be generated for one of the users based on the updated result.

摘要： Systems (490), methods (100, 200), and computer-readable and executable instructions (324, 424) are provided for estimating costs of behavioral targeting. Estimating costs of behavioral targeting can include scoring a topic with a behavioral targeting model (101, 201). Estimating costs of behavioral targeting can also include obtaining a plurality of data items including geographic location information (102, 202). Estimating costs of behavioral targeting can also include detecting (104, 204) and scoring (209) a sentiment from filtered data items regarding a topic within a region (104, 204). Estimating costs of behavioral targeting can include computing a penalty score for the topic in the region in response to the scored sentiment exceeding a threshold (213), (106, 206). Estimating costs of behavioral targeting can include adjusting the topic score in the region according to the penalty score (108, 208). Furthermore, estimating costs of behavioral targeting can include taking an action with respect to advertising based on the adjusted topic score (110, 210).
摘要翻译：系统（490），方法（100,200）和计算机可读和可执行指令（324,424）被提供用于估计行为目标的成本。估计行为定位成本可以包括使用行为定位模型评分主题（101,201）。估计行为定位的成本还可以包括获得包括地理位置信息（102,202）的多个数据项。估计行为定位的成本还可以包括从区域（104,204）内的关于主题的经过滤数据项的检测（104,204）和评分（209）得分（209）。估计行为定位的成本可以包括响应于超过阈值（213）（106,206）的评分情绪计算该区域中的主题的惩罚分数。估计行为定位的成本可以包括根据惩罚分数调整该地区的主题得分（108,208）。此外，估计行为定位的成本可以包括基于经调整的主题得分（110,210）采取关于广告的动作。

摘要： For each web page visited, a path is determined through a hierarchy of categories. The hierarchy of categories has levels from a most abstract level to a most concrete level. For each microblog entry of a microblog, a path is determined through the hierarchy of categories. Each microblog entry for which the path is similar to the path for at least one web page is determined as a selected microblog entry.
