Patent number: 9135370Abstract: Provided is a method of generating updating parameters. The method obtains search keywords used by users within a predetermined time period; counts the search keywords to obtain primary keywords, related keywords, co-search frequencies of each primary keyword and the respective related keywords being searched together, and search frequencies of the primary keywords being searched alone; computes first feature values based on the search frequencies of the primary keywords being searched alone; and then computes second feature values based on the first feature values and the co-search frequencies of the primary keywords and the respective related keywords. The second feature values serve as updating parameters for determining displaying modes of the related keywords. An apparatus of generating updating parameters, and a method and an apparatus of displaying related keywords according to the updating parameters are also provided.Type: GrantFiled: September 25, 2014Date of Patent: September 15, 2015Assignee: Alibaba Group Holding LimitedInventors: Lei Pan, Yuanhu Yao, Zhen Yang, Tianji Zhang

Patent number: 8768906Abstract: A method and a system of displaying related keywords are provided. The method includes: receiving a primary keyword inputted by a user and a request for retrieving keywords related to the primary keyword; recording a frequency of the retrieving request corresponding to the primary keyword; selecting a candidate group of related keywords based on the frequency from the groups of related keywords corresponding to the primary keyword; and displaying the related keywords in the candidate group of related keywords. The system includes: an interface unit, a recording unit, an acquiring unit and a displaying unit. The disclosed method and system retrieve different groups of related keywords based on the frequency of the request for retrieving keywords related to a certain primary keyword, and display the retrieved related keywords in a rotating manner and allow a user to obtain the related keywords in an easier and more complete way.Type: GrantFiled: August 28, 2007Date of Patent: July 1, 2014Assignee: Alibaba Group Holding LimitedInventors: Lei Pan, Yuanhu Yao, Weiwei Wang, Yu Zhang
