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 ...
