Abstract: Provided are systems and methods for selecting a hierarchical location corresponding to a geographic location of a client computer. In some embodiments, a request for location information may be received from a client computer. The request may include a token that enables determination of geolocation data based on the token. The geolocation data may include a list of hierarchical locations, such as a postal code, a city, a state, and a county, and each hierarchical location may be associated with a confidence measure. The hierarchical locations may be iteratively traversed from smallest to largest. If the confidence measure of a selected hierarchical location is greater than a threshold, the hierarchical location may be provided as the location information. If the confidence measure of the selected hierarchical location is less than the threshold, the next hierarchical location may be selected and the associated confidence measure compared to the threshold.

Abstract translation: 提供了用于选择对应于客户端计算机的地理位置的分层位置的系统和方法。 在一些实施例中，可以从客户端计算机接收对位置信息的请求。 请求可以包括能够基于令牌来确定地理定位数据的令牌。 地理位置数据可以包括诸如邮政编码，城市，州和县之类的分层位置的列表，并且每个分层位置可以与置信度量度相关联。 分层位置可以从最小到最大迭代地遍历。 如果所选分层位置的置信度大于阈值，则可以提供分层位置作为位置信息。 如果所选分层位置的置信度小于阈值，则可以选择下一个分层位置，并将相关的置信度量度与阈值进行比较。
