Description

【Technical field】 [0001] The present invention relates to the technical field of Internet information processing, in particular to a method and device for acquiring an organization's alias. 【Background technique】 [0002] The point of interest (POI) data in the electronic map usually includes information such as name, address, contact number, category, location coordinates, etc., which are used to represent the location entity in the electronic map, which can be a place name, or a company or unit and other organization names. When a user queries a point of interest, the search engine, after receiving the search term (query) input by the user, finds the data that matches the name of the point of interest and the search term, and returns relevant search results to the user.

Problems solved by technology

[0004] However, the name field of most of the current POI data uses the corresponding full name. Since the current search engine cannot automatically handle the correspondence between the full name and the alias, when the user uses the abbreviation or alias of the place name to query, For example, "Bird's Nest" is another name for "National Stadium". If only "National Stadium" is included in the POI database but not "Bird's Nest", when users search for the keyword "Bird's Nest", it is very likely that they will not be able to return the corresponding search results, which causes a lot of waste of data resources and affects user experience

[0005] Existing search engines can only rely on manual addition when dealing with the correspondence between full names and aliases

This will consume a lot of manpower, and it is also prone to untimely updates or omissions, which will result in not covering relevant search results, resulting in low recall rate and poor user experience
