Embodiments of methods and apparatuses for acquiring information are provided. One implementation of the method can include: determining an initial area corresponding to a target point of interest, and dividing the initial area corresponding to the target point of interest into a plurality of grids; and generating annotations of the plurality of grids respectively based on characteristics of the plurality of grids. Therefore, whether the user data associated with the each of the plurality of grids is used to generate the attribute of the target point of interest may be directly determined based on the annotation of the each of the plurality of grids, thereby saving the spending of the process of acquiring the user data required for generating the attribute of the target point of interest in data mining. The operation state of the target point of interest may be determined based on the annotation of the grid.

Method and apparatus for acquiring information

Embodiments of the present disclosure disclose a method and apparatus for acquiring information. A specific implementation of the method includes: acquiring a plurality of pieces of positioning data in a preset time period and a plurality of pieces of captured data captured by a WLAN probe device of a target point of interest in the preset time period; and finding, from the plurality of pieces of positioning data, a plurality of pieces of positioning data meeting a preset condition, and generating, based on the plurality of pieces of positioning data meeting the preset condition, indication information indicating whether the WLAN probe device being abnormal. The method realizes the evaluation of whether the WLAN probe device is abnormal, whether the deployment location of the WLAN probe device is reasonable, and whether it is necessary to add WLAN probe devices.

An objective of the present invention is providing a method and apparatus for providing recommended information. A method according to the present invention comprises steps of: determining, based on one or more pieces of content information in one or more webpages, whether the one or more pieces of content information may be used as recommended information, respectively; obtaining feature information of the recommended information if the content information is recommended information; determining ordering information of the each piece of recommended information based on the feature information of each piece of recommended information; wherein the method further comprises the following step: if a user's browsing operation on the webpage corresponds to at least one piece of recommended information, presenting the at least one piece of recommended information.

Method and apparatus for providing recommended information

The present disclosure provides a method and apparatus for determining relationship between POIs. The method comprises: obtaining a WiFi fingerprint uploaded by the user, the WiFi fingerprint comprising information of a wireless access point AP listing at a location where the user lies; determining a POI corresponding to each AP in each WiFi fingerprint; if the number of times that APs respectively corresponding to any two POIs occur in the same WiFi fingerprint exceeds a first threshold, determining the two POIs as being in a neighboring relationship. The solution of the present disclosure may be employed to save costs of manpower and material resources and improve accuracy of information.
