摘要： Methods and apparatus for a system providing group recommendations, event scheduling, and forming consensus agreements among a group of disparately located users are provided by the present principles. Communication among the disparately located users may be achieved through social media tools, online polling, chatting, and texting. The methods and apparatus allow a user profile to be constructed based on ratings that a user provides to items in a database. The items may comprise such things as restaurants, movie theaters, or other entertainment and group activities. The items may comprise feature vectors including attributes of the individual items. With user profiles constructed, the methods and apparatus may allow prediction of a rating that an individual with a particular user profile may give to a similar item in a database. The system may be used to predict the best choice for a group activity by considering the ratings of all users within a group.

摘要： The present invention concerns the replication of data, in particular the replication of data in a peer-to-peer network of mobile devices. Each device stores a plurality of data items. When two devices come into range, a decision as to whether to replicate a data item is made in dependence the extent to which that data item has been requested by other devices, and (b) the extent to which that data item is replicated on other devices. In this way, both the demand and supply of a data item are taken into account.

摘要： The present invention relates to searching, in particular guided searching through a database of stored objects. A user is presented with proposals of objects and is invited to select the objects she considers closest to the intended objective of her search. One of the presented objects that is not selected is then replaced with a different object and the user is invited to make a fresh selection. The procedure is repeated iteratively until the user is satisfied with the result. The choice of replacement object is made taking into account the users previous choices, thereby improving the efficacy of the search.

Communication among the disparately located users may be achieved through social media tools, online polling, chatting, and texting. The methods and apparatus allow a user profile to be constructed based on ratings that a user provides to items in a database. The items may comprise such things as restaurants, movie theaters, or other entertainment and group activities. The items may comprise feature vectors including attributes of the individual items. With user profiles constructed, the methods and apparatus may allow prediction of a rating that an individual with a particular user profile may give to a similar item in a database. The system may be used to predict the best choice for a group activity by considering the ratings of all users within a group. Individual ratings may be weighted to give higher or lower priority to some users. The system may also recommend activities based on the users participating in the group, or allow the users to select other activities to be considered. In one exemplary embodiment, the system selects recommendations for the users, comprising elements such as movie title, theater location, seating, and prices. The system sends notifications to the users, collects preferences from the users, and determines a choice based on the collected preferences. The users are notified of the choice and given an opportunity to purchase tickets electronically. If so, they may receive electronic tickets, coupons, promotions, or offers.

摘要： A method is provided for performing a content search through comparisons, where a user is presented with two candidate objects and reveals which is closer to the user's intended target object. The disclosed principles provide active strategies for finding the user's target with few comparisons. The so-called rank-net strategy for noiseless user feedback is described. For target distributions with a bounded doubling constant, rank-net finds the target in a number of steps close to the entropy of the target distribution and hence of the optimum. The case of noisy user feedback is also considered. In that context a variant of rank-nets is also described, for which performance bounds within a slowly growing function (doubly logarithmic) of the optimum are found. Nu-merical evaluations on movie datasets show that rank-net matches the search efficiency of generalized binary search while incurring a smaller computational cost.

摘要： A method for recommending content items to a user is provided. It includes: (i) receiving one of at least an acceptance input and a rejection input from a user in relation to content presented to the user; (ii) in response to an acceptance input, rendering the presented content, or in response to a rejection input, selecting fresh content for presentation; and, (iii) repeating steps (i) and (ii) until a acceptance input is received. Content is selected in dependence on a associated probability associated with that content. The probability is increased in response to an acceptance input, the increase being determined in part on a measure of a predicted reduction in user satisfaction that would be associated with an additional rejection input.

摘要： In interactive content search through comparisons, a search for a target object in a database is performed by finding the object most similar to the target from a small list of objects. A new object list is then presented based on the earlier selections. This process is repeated until the target is included in the list presented, at which point the search terminates. A solution to the interactive content search problem is provided under the scenario of heterogeneous demand, where target objects are selected from a non-uniform probability distribution. It has been assumed that objects are embedded in a doubling metric space which is fully observable to the search algorithm. Based on these assumptions, an efficient comparison-based search method is provided whose cost in terms of the number of queries can be bounded by the doubling constant of the embedding c , and the entropy of demand distribution, H . More precisely, the present principles show that the average search costs scales C F = O(c 5 H) , which improves upon the previously best known bound and is order optimal for constant c .
摘要翻译：在通过比较的交互式内容搜索中，通过从小的对象列表中找到与目标最相似的对象来执行数据库中的目标对象的搜索。然后基于先前的选择来呈现新的对象列表。重复该过程直到目标被包括在所呈现的列表中，此时搜索终止。在异构需求的场景下提供了交互式内容搜索问题的解决方案，其中从不均匀的概率分布中选择目标对象。已经假设对象被嵌入在搜索算法中完全可观察到的加倍度量空间中。基于这些假设，提供了一种有效的基于比较的搜索方法，其查询数量的成本可以由嵌入c的倍增常数和需求分布熵H限制。更准确地说，本原理显示平均搜索成本缩放CF = O（c 5 H），其改善了先前最为已知的界限，并且对于常数c是顺序优化的。
