    Abstract: Trust networks in a recommender system are automatically updated in response to user feedback on recommendations provided by the trust network. In response to a user request, a set of referrals is generated, with some of the referrals being recommended based on judgment data received from members of the trust network. If the user evaluates the recommended referral, a trust parameter for at least one of the trust network members is updated based on the evaluation.

    Abstract: Method, system, and programs for providing enhanced search term suggestions. A set of incomplete search terms indicating a sequence of search terms entered may be received. It may be detected that the sequence contains a descending phase followed by an ascending phase. In response to the detection, a pair of misinput term and corresponding corrected term may be identified in the set of incomplete search terms. A probability with respect to the misinput term is a misinput of the corresponding corrected term may be determined based on a historical context. Using such a probability, an incomplete search term containing the misinput term may be corrected. One or more proposed search terms may be determined based on the corrected incomplete search term for suggestion to the user.

    Abstract: The present invention is directed towards systems and methods for trust propagation. The method according to one embodiment comprises calculating a first feature vector for a first user, calculating a second feature for a second user and comparing the first feature vector with the second feature vector to calculate a similarity value. A determination is made as to whether the similarity value falls within a threshold. If the similarity value falls within the threshold, a relationship is recorded between the first user and the second user in a first user profile and a second user profile.

    Abstract: The present teaching relates to methods, systems, and programming for indexing and providing suggestions. In one example, a method, implemented on at least one machine each of which has at least one processor, storage, and a communication platform connected to a network for providing a suggestion is presented. An input from a user is first received. At least a part of the input is processed to generate a plurality of tokens. At least one multi-layered key is generated based on one or more of the plurality of tokens. One or more suggestions are retrieved based on the at least one multi-layered key. At least one of the one or more suggestions is provided to be presented to the user.

    Abstract: Techniques are provided for automatically determining when to trigger instant search. In one technique, while a user is entering text to formulate a search query, and prior to receiving an indication that the user has completed formulation of the search query, a search assistant system determines the most popular queries that include the text the user has already entered. The search assistant system then determines whether to proactively provide, to the user, search results for the top-candidate of those completed queries. That determination may take into account factors such as whether the top-candidate qualifies as a dominant completed query, a richness metric determined for the search results for the particular completed query, and/or a satisfaction metric determined for the search results for the particular completed query. If the search assistant system determines to proactively provide search results for the particular completed query, the search results for the particular completed query are presented to the user prior to receiving any indication that the user has completed formulation of the search query.

    Abstract translation: 提供了自动确定何时触发即时搜索的技术。 在一种技术中，当用户正在输入文本以制定搜索查询时，并且在接收到用户已经完成了搜索查询的制定的指示之前，搜索助理系统确定包括用户已经存在的文本的最流行的查询 输入 搜索助理系统然后确定是否主动地向用户提供搜索结果以获取那些完成的查询的顶级候选者。 该确定可以考虑诸如顶级候选人是否被认为是主要完成查询，针对特定完成查询的搜索结果确定的丰富度量度和/或针对特定完成查询的搜索结果确定的满意度度量的因素 查询。 如果搜索助理系统确定主动地为特定的完成查询提供搜索结果，则在接收到用户已经完成了搜索查询的制定的任何指示之前，向用户呈现特定完成查询的搜索结果。
