example 1

[0099] Specifically, it can support the limitation of nearby range based on latitude and longitude. Take the technical implementation of the functional sentence "bus station near Hisense Building" as an example, determine the type of demand through the short text classification algorithm, and extract the first noun "Hisense Building" and the second noun "Bus station", according to the related word "nearby", the matching sentence template is "*2 near *1", and the extracted "Hisense Building" and "bus station" are added to the sentence template and passed to the post At the end, search the range with the location of "Hisense Building" as the center, determine all bus stops within the search range with a certain step size, and gradually expand the search radius until the searched bus stop is found.

[0100] Taking the technical realization of the functional sentence pattern "the nearest subway to Hisense Building" as an example, the demand is judged through the short text classifi...

example 2

[0107] Specifically, attribute restrictions based on business districts / administrative regions can be supported. Taking the technical implementation of the functional sentence "What are the Japanese-flavored stores in the Licang business district" as an example, the short text classification algorithm is used to determine the type of demand and extract the first noun "" Licang business circle" and the second noun "Japanese food flavor store", the distance relation word is the implied relation word "nei". The matching sentence template is found to be "*1*2", and the extracted "Licang business district" and "Japanese food store" are passed to the backend, and the backend calls the retrieval corresponding to the sentence template The specific process is as follows:

[0108] Retrieve the POI entities included / connected (that is, within the search distance) of the first point of interest "Licang business circle", find out the POI store whose flavor type is Japanese cuisine, and ret...

[0112] Specifically, it can support the limitation based on roads, intersections, and scope. Taking the technical realization of the functional sentence "what are the pharmacies on Ningxia Road" as an example, the short text classification algorithm is used to determine the type of demand, and the first noun "Ningxia Road" and the second noun are extracted. For the noun "drugstore", the relative word representing the distance relationship is "上", "上" is a fuzzy distance word, and the matching sentence template is found to be "*2 on *1", and "Ningxia Road" and "Drugstore" is passed to the backend, and the backend invokes the search method corresponding to the sentence template to search and query. The specific process is as follows:

[0113] Based on the extraction of "Nanjing Road" and "pharmacy", the backend searches for the entity "Nanjing Road" in the knowledge map, and finds the POI connected to the entity within the retrieval distance, selects the entity whose type is phar...

Abstract

The invention provides an interest point display method and device. The method comprises the steps of receving a search requirement input by a user, generating search requirement text information, extracting a first noun, a second noun and relation words representing distance relations from search requirement text information, and in the character sequence of the search requirement text information, wherein a first noun is ahead of a second noun; determining a first interest point corresponding to the first noun in the knowledge graph data, determining a retrieval distance corresponding to therelational word, and searching for a second interest point, the distance between which and the first interest point is not greater than the retrieval distance, the second interest point correspondingto the second noun; and outputting the second interest point, wherein the second interest point is used for displaying on a user interaction interface. Fuzzy query is supported by analyzing the relationship between the interest points, and the precision of retrieval demand information in existing navigation software and life service software is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for displaying points of interest. Background technique [0002] Smart travel service applications generally provide end users with geographic location information query services by performing map-based path calculations on existing electronic maps based on the query information provided by users, and provide end users with location information near designated locations through integrated other service interfaces. Specify POI (Point of Interest, point of interest) information query. [0003] At present, mainstream intelligent travel service applications use the query information provided by users as keywords to query geographic location information, but this query method requires users to provide more accurate query information, and cannot realize fuzzy location queries, fuzzy problem queries, and multi-purpose queries. A series of query me...
