Embodiment 1

[0085] figure 2 A flow chart of a method for establishing a POI state recognition model provided by the embodiment of the present application, such as figure 2 As shown in , the method may include the following steps:

[0086] In 201, training data is obtained, wherein the training data includes: text and labeling results of POI names and POI states contained in the text.

[0087] When acquiring training data, some texts including POI names and POI states may be marked manually as training data. However, this method can only generate a small amount of data due to the limitation of manpower, which will bring certain restrictions on the accuracy of model training. Here, as a preferred embodiment, such as image 3 The methods shown in to obtain training data include:

[0088] In 301, a pre-trained POI recognizer is used to obtain text containing POI names from the Internet.

[0089] Crawl the Internet text from the webpage, in order to ensure that the text contains POI inf...

Embodiment 2

[0123] Figure 5 The flow chart of the method for obtaining POI status information provided by the embodiment of this application, the method is based on figure 2 The POI state recognition model established by the flow shown. Such as Figure 5 As shown in , the method may include the following steps:

[0124] In 501, texts containing POI information within a preset period of time are obtained from the Internet.

[0125] In order to ensure the real-time performance of POI status information, the most recent text can be crawled from the Internet, and then POI information recognition can be performed on the obtained text using the pre-trained POI recognizer, and the text containing POI information can be retained.

[0126] For relevant records about the POI recognizer, refer to the relevant records for step 301 in Embodiment 1, which will not be repeated here.

[0127] In 502, the text is recognized by using the POI state recognition model obtained through the training, and ...

Embodiment 3

[0141] Figure 7 The device structure diagram for establishing the POI state recognition model provided by the embodiment of the present application, such as Figure 7 As shown in , the device may include: an acquisition unit 01 and a training unit 02, wherein the main functions of each constituent unit are as follows:

[0142] The acquiring unit 01 is responsible for acquiring training data, which includes: text and labeling results of POI names and POI states contained in the text.

[0143] Specifically, the acquisition unit 01 can first obtain the seed text and the POI name contained in the seed text and the labeling result of the POI state corresponding to the POI name; then, use the POI name of the same type as the POI name contained in the seed text in the POI database , replace the POI name in the seed text to obtain the extended text; obtain the training data from the seed text and the extended text.

[0144] Among them, when obtaining the seed text, you can use the ...

Abstract

The invention discloses a POI (Point of Interest) state information obtaining method and device, equipment and a computer storage medium, and relates to the field of big data. According to the specific implementation scheme, the method comprises the steps of obtaining a text containing POI information in a preset time period from the Internet; identifying the text by using a pre-trained POI stateidentification model to obtain a two-tuple in the text, the two-tuple comprising a POI name and POI state information corresponding to the POI name, wherein the POI state recognition model performs POI name label prediction and POI state label prediction on a word sequence corresponding to the text, and aligns a POI name label prediction result with a POI state label prediction result to obtain the binary group. According to the invention, the labor cost can be saved, and the timeliness and accuracy are improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, device and computer storage medium for obtaining POI status information in the field of big data. Background technique [0002] POI (Point of Interest) refers to a point of interest. It is a term in geographic information systems and generally refers to all geographical objects that can be abstracted into points. A POI can be a house, a shop, a mailbox, a bus stop, A school, a hospital, etc. The main purpose of POI is to describe the location of things or events, thereby enhancing the ability to describe and query the location of things or events. [0003] In Internet map applications, POI plays a very important role. By using POI users can easily find a place of interest and the route to that place on the map. However, due to the influence of urban planning and other factors, the information of some POIs will change over time, such as newly a...
