The invention provides a method for completing data acquisition and tourist knowledge map storage and update in a tourist scene, and fig. 1 is a flow chart of a tourist knowledge map updating method in an embodiment of the invention, and specifically, the tourist knowledge map updating method comprises the following steps:
s100: acquiring tourism data;
s200: extracting a target POI entity and attribute information of the target POI entity from the travel data; the target POI entity attribute information comprises at least one of target POI name, target POI alias, target POI pinyin, target POI longitude, target POI latitude, target POI address and target POI comment.
S300: determining a target POI entity to be updated according to the attribute information of the target POI entity;
s400: obtaining the relation information of each target POI entity according to the tourism data and judging whether the relation information of the target POI is accurate or not;
if the relationship information is accurate, S500: the target POI entity relationship information is determined as target POI relationship information to be updated;
s600: and storing the target POI entity to be updated and the target POI entity relationship information to be updated to obtain an updated travel knowledge map.
In an embodiment, the step of obtaining travel data described in step S100 includes:
s110: periodically synchronizing POI data from structured data of an internal system, or/and
s120: and POI data are acquired from the webpage through a web crawler.
After the step S200 of extracting the attribute information of the target POI entity from the travel data, the method may further include:
s210: judging whether the target POI entity attribute information meets a configured verification rule;
if the configured check rule is satisfied, S220: and determining the target POI entity attribute information as target POI entity attribute information to be updated.
Different verification rules configured for different target POI entity attribute information are different, and the verification rules are configured according to different characteristics of each attribute, for example, the verification rule of the target POI longitude or the target POI latitude can be a numerical range for setting the target POI longitude or the target POI latitude, if the target POI longitude or the target POI latitude of one target POI entity attribute information exceeds the numerical range, the verification rule is not satisfied, at this time, the target POI entity attribute information is considered to be inaccurate, and the attribute information is not used as the target POI entity attribute information to be updated; if the verification rule of the attribute of the target POI comment is that the set key word cannot appear, and when the set key word appears in the target POI comment, the verification rule is not satisfied. If the length of the target POI name is detected to be too long, the check rule is considered not to be satisfied, and the like, which is not described herein again.
The step S300 of determining the target POI entity to be updated according to the attribute information of the target POI entity includes the following steps:
s310: calculating the similarity of each target POI entity according to the attribute information of the target POI entities;
s320: and merging the target POI entities with the similarity larger than the threshold value to obtain the target POI entities to be updated.
In the above steps S310 and S320, the target POI entities with attribute information similarity greater than the threshold are determined to be the same entity for merging, and similarly, the calculation methods of the similarity of different attribute information are different, and for the target POI entities with different names, if the similarity of longitude and latitude of two target POIs is greater than a threshold and the similarity of addresses of two target POIs is also greater than a threshold, it is determined that the two POI entities are the same entity for attribute merging. The steps reduce the redundancy of the data and ensure the simplification of the data to be updated.
And the relation information of each target POI entity comprises the superior-inferior relation of each target POI entity or/and the destination relation of each target POI entity.
The step of obtaining the relationship information of the target POI entity according to the tour data and judging whether the relationship information is accurate in the step S400 includes:
s410: acquiring the superior-subordinate relationship information and/or destination relationship information of a target POI entity according to the tourism data;
s420: detecting whether a ring exists in the superior-inferior relation of each target POI entity through a depth-first search algorithm, and if the ring does not exist, determining that the superior-inferior relation exists among the target POI entities and the relation information is accurate; for example, the yellow mountain welcoming pine scenic spot of the target POI entity and the yellow mountain scenic spot of the target POI entity belong to a superior-inferior relationship. In step S420, if the obtained target POI entity relationship information does not form a loop with an edge relationship in the existing map, it is considered that this edge relationship can be fused into the existing map, and if the edge relationship forms a loop with the existing map, the variable relationship cannot be fused into the existing map. The method for checking whether the upper-level and lower-level relationships of the target POI entities are accurate is not limited to the upper depth-first search algorithm, and a minimum spanning tree algorithm or a set checking rule can be adopted, which is not described herein again.
Judging whether the relationship information is accurate may further include:
s430: and verifying whether the destination where each POI entity is located is correct or not through the boundary fence data of the destination, wherein if the destination is correct, the destination relation information of the POI entities is accurate. For example, if the destination relationship with the destination of the target POI entity is the beijing dongchun, the accuracy of the relationship information between the longitude and the latitude of the target POI entity can be determined by determining whether the longitude and the latitude of the target POI entity fall into the border fence data of the beijing dongchun. Wherein, the step S420 and the step S430 have no sequence.
According to some examples of the present invention, the saving the target POI entity to be updated and the target POI entity relationship information to be updated to obtain the updated travel knowledge map comprises the following steps:
fusing the target POI entity to be updated, the attribute information of the target POI entity to be updated and the relation information of the target POI entity to be updated to the current tourism knowledge map as nodes and edges of the tourism knowledge map;
and obtaining an updated travel knowledge map based on the fused result.
The data updated by the tourist knowledge map in the invention can be divided into two parts from the source: synchronizing from the structured data of the internal system, and acquiring from external networks such as a travel official website, a WeChat public number, a microblog and the like by adopting a web crawler. The data of the two parts can be acquired periodically or at regular time, the original data acquired by the web crawler generally needs to be subjected to preprocessing steps such as cleaning, useless data such as labels and pictures are removed, and only text description is reserved. Due to the real-time nature of the external network information, the data acquired by the web crawler can be used to supplement missing attribute information and relationship information in the target POI entity in the knowledge graph.
According to the invention, through acquiring the tourism data, the target POI entity contained in the tourism data and the relation information of the target POI entity are fused into the tourism knowledge map, and through the continuous iteration processing mode, the construction efficiency of the tourism knowledge map is greatly improved, unnecessary delivery and repeated operation time is compressed to the greatest extent, and the labor cost is greatly reduced. Meanwhile, the collected target POI entity and the target POI entity relation information marked to be updated can be updated to the travel knowledge map after manual examination. The updated travel knowledge graph can more intuitively show the association relation of the nodes and edges of the graph to the user through a visual display page, data summary statistics, interface documents and the like, and the graph is more diversified in use and calling modes.
