Problems solved by technology
[0002] A large number of news texts are generated for the whole country and various parts of the world every day. These news texts may contain millions of data volumes. Such a huge amount of data will consume a lot of manpower and material resources only by manually identifying news occurrences. Therefore, it is necessary to use The machine automatically recognizes the location of the news from the news text, but there are also various difficulties in the process of automatically identifying the location of the news
[0003] Usually, if you want to get the place where the news happened, the ideal situation is that there is only one place mentioned in the news, and it is the place where the news happened, but this is rarely the case in the actual news. , it will also involve location information that has nothing to do with the location of the news. In this case, it is difficult to accurately determine the location of the news from multiple locations.

The invention provides a news occurrence place identification method and device, a storage medium and computing equipment. The method comprises the following steps: extracting multiple pieces of entity information from a news text; if any entity information is site information, constructing a first site tree according to the entity information; if any entity information is not the location information, analyzing the location information related to the entity information, and constructing a second location tree according to the location information related to the entity information; fusing the location information contained in the first location tree and the location information contained in the second location tree, and identifying the news location based on the fused location information. Through the site information related to the entity information in the constructed second site tree, the site information in the news text can be effectively supplemented, and the recognition accuracy and recall rate of the news occurrence site in the news text are improved.
