Abstract: A method including classifying a plurality of users into different user groups according to at least one attribute information of the plurality of users; determining a keyword corresponding to each user group according to historical user behavior logs of different user groups; receiving a request of a current user for accessing a current transaction object, and determining a user group of the current user according to attribute information of the current user; segmenting an original title of the current transaction object into word segments, and determining a word segment matching the keyword corresponding to the user group of the current user in the word segments; generating a new title of the transaction object according to the matching word segment for display at a user client terminal. The techniques of the present disclosure ensure that a title displayed to a user is short and meets personalized demands of the user.

Abstract: Control servers of various IoT service providers are pre-registered with a gateway platform, so that a client terminal is decoupled from the control servers of the IoT service providers and the client terminal becomes a universal terminal corresponding to the gateway platform. The control servers of the IoT service providers and controllers installed by the IoT service providers no longer uniquely correspond to the client terminal, and a user may send a control request to control servers of different IoT service providers via the client terminal and the gateway platform. Thus, if the user replaces a damaged controller with a controller of another IoT service provider or uses controllers of more than two IoT service providers at the same time, the user does not need to change a new client terminal or use more than two client terminals at the same time.

Abstract: A search request sent by a user is received to obtain one or more query words included in the search request. Historical operating information relating to a data object in a search result corresponding to the query words is conducted statistics. An attribute of the data object is selected as a specified attribute to generate a probability distribution model of the attribute value on the specified attribute of the data object. A respective probability corresponding to the attribute value of each data object on the specific attribute in the research result corresponding to the search request sent by the current user is calculated by using the probability distribution model. The output rank of the data objects in the search result is adjusted by using the probability. The present techniques improve reasonability of displaying the data objects in the search result and provide more accurate result.

Abstract translation: 接收用户发送的搜索请求以获得包括在搜索请求中的一个或多个查询词。 对与查询词相对应的搜索结果中的数据对象有关的历史操作信息进行统计。 选择数据对象的属性作为指定属性，以生成数据对象的指定属性上的属性值的概率分布模型。 通过使用概率分布模型计算与当前用户发送的搜索请求对应的研究结果中的每个数据对象的特定属性的属性值相应的概率。 通过使用概率来调整搜索结果中的数据对象的输出等级。 本技术提高了在搜索结果中显示数据对象的合理性，并提供更准确的结果。
