Abstract: 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.

Abstract: 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.

Abstract: The present disclosure provides a hotspot information analysis method and apparatus and a computer storage medium. The hotspot information analysis method comprises: extracting, from Internet data, hotspot data describing a hotspot event; performing analysis for association of business data in the whole business market related to a business transaction and the hotspot data, and obtaining a correspondence relationship between candidate hotspot data and candidate business data, wherein the candidate hotspot data refers to hotspot data in the hotspot data related to the business transaction, and the candidate business data refers to business data in the business data related to the hotspot event; merging and processing the candidate hotspot data according to the correspondence relationship between the candidate hotspot data and candidate business data, and obtaining target hotspot data and target business data corresponding to the target hotspot data.

Abstract: A rapid preparation method of high-quality hot water, includes steps of: a) calculating a temperature difference between an inlet water temperature and an predetermined outlet water temperature, determining an adjacent heating power pair from heating curves of the pipeline heater according to the temperature difference and a predetermined flow rate, wherein the heating power pair is corresponding to one of time points in a slow nonlinear heating area K, then selecting the heating power pair for preparing to heat water in the pipeline heater; and b) inputting the water with the predetermined flow rate into the pipeline heater, heating with one of the heating power pair selected in the step a) in such a manner that the water in the pipeline heater is heated according to the K area of the pipeline heater, obtaining the water with the target water temperature from an outlet.
