Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a method, apparatus, and electronic device for processing point-of-interest (POI) data. Background Technology

[0002] With the development of technology, electronic maps have brought convenience to people's lives. The graphics displayed in electronic maps are basically composed of points, lines, and polygons, and Points of Interest (POIs), as an important component of point data, are an indispensable part of electronic maps. Their quality directly determines the user experience of electronic maps.

[0003] In existing technologies, each POI typically contains data such as name, address, coordinates, and type. However, this data may be incomplete or contain errors, especially the name of the POI. This is because the personnel responsible for collecting the POI name and the area may be different, or they may collect the data at different times. Furthermore, since many buildings (such as residential communities) do not have signs for their doors or entrances, or only have abbreviations for the doors, the data collectors often judge the names based on experience or add abbreviations to the doors. This leads to many incorrect names for doors or entrances, causing considerable inconvenience to travelers. Summary of the Invention

[0096] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0097] Points of Interest (POIs) refer to any geographic object that can be abstracted as a point, especially geographic entities closely related to people's lives. They typically include attributes such as name, coordinates, address, and type (label). In geographic information systems, a building, a company, a residential area, a gate, a parking lot, a bus stop, etc., can all be considered POIs.

[0098] Principal-Child Point Relationships: These describe the relationships between Points of Interest (POIs). They typically include naming relationships and containment relationships between regions / areas, such as:

[0099] (1) The principal-sub-point relationship established by the inclusion relationship between the area surfaces: If the park where "Sogou Map" is located is "Tsinghua Science Park", then the POI "Sogou Map" and POI "Tsinghua Science Park" can be described as having a principal-sub-point relationship, with "Tsinghua Science Park" being called the principal point and "Sogou Map" being called the sub-point.

[0100] (2) The master-child relationship established through the association between names: The POI “Sohu Network Building - East Gate” and the POI “Sohu Network Building” are described as having a master-child relationship, with “Sohu Network Building” being called the master point and “Sohu Network Building - East Gate” being called the child point;

[0101] Sub-point abbreviation: The name of the sub-point after removing the main point name. Sub-points may or may not have an abbreviation. For example, in the relationship in "(1)" above, the sub-point "Sogou Map" has no abbreviation; in the relationship in "(2)" above, the abbreviation of the sub-point "Sohu Network Building - East Gate" is "East Gate";

[0102] Name container: The main point in the main and child points that are associated by name is the name container, such as "Sohu Network Building" in "(2)" above;

[0103] Area container: The principal point among the principal child points associated with the area surface is the area container, such as "Tsinghua Science Park" in "(1)" above.

[0104] In existing technologies, the names in Points of Interest (POIs) may contain errors, causing considerable inconvenience to travelers. Therefore, it is necessary to correct the names in POIs. In this embodiment of the invention, point of interest data is acquired, which includes the name and coordinates of sub-points. An abbreviation for the sub-point is determined based on its name. One or more area containers to which the sub-point belongs are determined based on its coordinates, and a target area container is determined from these one or more area containers. A constructed name for the sub-point is generated based on the target area container and the abbreviation. An alias for the sub-point is obtained based on the area container. A target name is determined based on the alias and the constructed name, and this target name replaces the name of the sub-point in the point of interest data. This avoids delays caused by incorrect sub-point names.

[0105] Reference Figure 1 The diagram illustrates a flowchart of an embodiment of a point-of-interest (POI) data processing method according to the present invention. The method may specifically include the following steps:

[0106] Step 101: Obtain point of interest data, which includes the name and coordinates of the sub-points;

[0107] Points of Interest (POIs) data can include information such as the name and coordinates of sub-points. Sub-points can be doors or entrances / exits, etc. The coordinates of a sub-point include a series of latitude and longitude coordinates, which can be used to determine the area corresponding to the sub-point. The name of a sub-point consists of a name container (i.e., the main point) and a short name for the sub-point. For example, if the name of a sub-point is "Jiaming Tongcheng - South Gate", then "Jiaming Tongcheng" is the name container for the sub-point, and "South Gate" is the short name for the sub-point.

[0108] Step 102: Determine the abbreviation of the sub-point corresponding to the sub-point based on the name of the sub-point;

[0109] In a practical implementation, the name container and abbreviation of the sub-point can be obtained by separating the name of the sub-point.

[0110] Step 103: Determine one or more area containers to which the sub-point belongs based on the coordinates of the sub-point, and determine the target area container from the one or more area containers;

[0111] Specifically, the region where a sub-point is located can be determined based on its coordinates, and further, one or more area containers to which the sub-point belongs can be determined based on its region. For example, the area containers to which the sub-point belongs based on its coordinates could be: Jiaming Tongcheng, Jiaming Tongcheng Area F. Furthermore, a target area container can be determined from the one or more area containers to which the sub-point belongs. This target area container is the area closest to or innermost of the sub-point, for example, Jiaming Tongcheng Area F.

[0112] Step 104: Using the target region container and the abbreviation of the sub-point, generate the construction name of the sub-point;

[0113] Specifically, the name of the sub-point can be reconstructed by combining the target area container and the abbreviation of the sub-point to generate the constructed name of the sub-point. For example, if the target area container is: Jiaming Tongcheng F District, and the abbreviation of the sub-point is: South Gate, then the constructed name of the generated sub-point is: Jiaming Tongcheng F District - South Gate.

[0114] Step 105: Obtain the alias corresponding to the sub-point based on the region container;

[0115] Among them, the alias of a sub-point is a name other than its formal or standardized name. The alias of a sub-point can be determined from collected user feedback information. In some application scenarios, different users may have different names for the same sub-point (such as a door or entrance / exit). These different names for the sub-point can be collected as the alias of the sub-point. For example, the alias of a sub-point can be Jiaming Tongcheng F District - South Gate, Jiaming Tongcheng F District - Southeast Gate, Jiaming Tongcheng F District - South Gate 1, Jiaming Tongcheng F District - South Gate 2, etc.

[0116] Step 106: Determine the target name based on the alias corresponding to the sub-point and the constructed name, and replace the name of the sub-point in the point of interest data with the target name.

[0117] Specifically, we can determine whether a construct name exists in the alias corresponding to the sub-point. If a construct name exists in the alias corresponding to the sub-point, the construct name can be directly determined as the target name. For example, if "Jiaming Tongcheng F District - South Gate" exists in the alias of the sub-point, then the target name is determined to be "Jiaming Tongcheng F District - South Gate", and the initial name of the sub-point "Jiaming Tongcheng - South Gate" is corrected to "Jiaming Tongcheng F District - South Gate".

[0118] In a preferred embodiment of the present invention, step 106 may specifically include the following sub-steps:

[0119] Determine whether there is a directional word in the abbreviation of the sub-point;

[0120] If the abbreviation of the sub-point contains a directional term, determine the directional region to which the sub-point belongs in the target area container based on the coordinates of the sub-point, and determine whether the directional term meets the directional conditions based on the directional region;

[0121] If the directional term meets the orientation condition, then the name of the sub-point in the point of interest data will be replaced by the target name.

[0122] In this embodiment of the invention, when replacing the name of a sub-point in the point of interest data with the target name, it can be further determined whether the directional word in the target name is reasonable, so that if the directional word is reasonable, the target name can be used to replace the name of the sub-point in the point of interest data.

[0123] Specifically, it can be determined whether the abbreviation of a sub-point contains a directional word. For example, if the abbreviation of a sub-point is "South Gate," then "South" is a directional word, indicating the presence of a directional word in the abbreviation. If a directional word is present in the abbreviation, the directional region to which the sub-point belongs within the target area container is determined based on its coordinates. In practice, the center point of the area (i.e., the target area container) is first calculated: the minimum and maximum longitude coordinates (Xmax and Xmin) are obtained based on the area's longitude coordinates; the minimum and maximum latitude coordinates (Ymax and Ymin) are obtained based on the area's latitude coordinates. Therefore, the coordinates of the center point can be calculated as: Longitude = (Xmin + Xmax) / 2, Latitude = (Ymin + Ymax) / 2. The area is then divided based on its center point, for example, into East, West, South, North, Southeast, Southwest, Northwest, and Northeast regions. Figure 2 As shown. Then, based on the coordinates of the sub-point, the directional region to which the sub-point belongs in the target area container can be determined. For example, whether "Jiaming Tongcheng F District - South Gate" belongs to the southern region of the area container "Jiaming Tongcheng F District".

[0124] Furthermore, the system can determine whether a directional term meets the location criteria based on the directional region. If the directional term meets the location criteria, the name of the sub-point in the point of interest data is replaced with the target name. For example, if the directional term "south" belongs to the "southern region," then the directional term is considered to meet the location criteria. In practical implementation, since different geographic entities are built in different directions, it can be set that as long as the directional term is not in the opposite region of the directional region to which the corresponding sub-point belongs, the directional term is considered to meet the location criteria. For example, if the directional region to which the sub-point belongs is "southern region," and the opposite region of "southern region" is "northern region," then as long as the directional term is not "north," the directional term is considered to meet the location criteria. Figure 3 As shown, "non-eastern region" is the reverse region of the eastern region, "non-western region" is the reverse region of the western region, "non-southern region" is the reverse region of the southern region, "non-northern region" is the reverse region of the northern region, "non-southern region" is the reverse region of the southeastern region, "non-southern region" is the reverse region of the southwestern region, "non-northwestern region" is the reverse region of the northwestern region, and "non-northeastern region" is the reverse region of the northeastern region.

[0125] In a preferred embodiment of the present invention, step 106 includes:

[0126] Determine whether the constructed name exists in the alias corresponding to the sub-point; if the constructed name exists in the alias corresponding to the sub-point, then determine that the constructed name is the target name.

[0127] In this embodiment of the invention, it is determined whether a construction name exists in the alias corresponding to the sub-point; if a construction name exists in the alias corresponding to the sub-point, the construction name can be directly determined as the target name. For example, if the sub-point alias contains "Jiaming Tongcheng F District - South Gate", then the target name is determined to be "Jiaming Tongcheng F District - South Gate".

[0128] In a preferred embodiment of the present invention, step 106 further includes:

[0129] If the construction name is not found in the alias corresponding to the sub-point, the abbreviation of the sub-point is expanded to generate multiple first construction names; from the multiple first construction names, the name belonging to the alias corresponding to the sub-point is determined as the target name.

[0130] Here, the first constructive name refers to the name reconstructed after expanding the abbreviation of the sub-point. In this embodiment of the invention, if there is no constructive name in the alias corresponding to the sub-point, the abbreviation of the sub-point can be expanded to obtain multiple first constructive names, for example, by synonym substitution. Furthermore, the name belonging to the alias corresponding to the sub-point can be determined from the multiple first constructive names as the target name.

[0131] In a preferred embodiment of the present invention, the abbreviation of the sub-point is expanded to obtain a plurality of first construction names, including:

[0132] The abbreviation of the sub-point is expanded according to the direction name and / or according to the numerical value to obtain multiple first construction names.

[0133] Specifically, the abbreviation of a sub-point can be expanded according to its direction name. For example, if the abbreviation of a sub-point is "West Gate", then the abbreviation of that sub-point can be expanded to "Southwest Gate", "Northwest Gate", etc. Alternatively, the abbreviation of a sub-point can be expanded according to its numerical value. For example, the abbreviation of a sub-point can be expanded to "West Gate 1", "West Gate 2", ... "West Gate N". Alternatively, the abbreviation of a sub-point can be expanded both according to its direction name and its numerical value, such as "Southwest Gate 1", "Southwest Gate 2", ... "Southwest Gate N", "Northwest Gate 1", "Northwest Gate 2", ... "Northwest Gate N".

[0134] Furthermore, by reconstructing according to the target area container and the expanded sub-point abbreviation, multiple first construction names are obtained, such as "Ruidu International South District - Southwest Gate", "Ruidu International South District - Northwest Gate", "Ruidu International South District - West Gate 1", "Ruidu International South District - West Gate 2"... "Ruidu International South District - Northwest Gate N", etc.

[0135] In a preferred embodiment of the present invention, the method further includes:

[0136] If no alias exists for the sub-point, determine the partition term in the target region container and delete the partition term;

[0137] The name container corresponding to the sub-point is determined based on the name of the sub-point, and the similarity between the target region container after deleting the partition term and the name container is determined.

[0138] If the similarity is greater than a preset threshold, a second constructed name is generated based on the target region container after deleting the partition term and the abbreviation of the sub-point;

[0139] The second constructed name replaces the name of the sub-point in the point of interest data.

[0140] In this embodiment of the invention, when there is no alias corresponding to a sub-point, the partition word in the target area container is determined and the partition word is deleted. For example, the partition word in "Jintian Park - North District" is "North District", and after removing the partition word, it becomes "Jintian Park".

[0141] Then, the name container corresponding to the sub-point is determined by separating the sub-point's name, and the similarity between the target region container and the name container after deleting the partition term is calculated. In the specific implementation, the similarity is calculated as follows: Step 1: Remove the administrative division part from the names of the region container and the name container respectively; Step 2: Obtain the maximum common substring from the names of the region container and the name container after removing the administrative division; Step 3: Calculate the proportion of the maximum common substring in each name; Step 4: When the proportion of the maximum common substring reaches a preset threshold (e.g., 80%) of their original names (after removing the administrative division part), it is necessary to continue to check whether their non-common substrings contain different directional words and numeric characters. If different directional words or numeric characters exist, the similarity drops to 0.

[0142] By determining whether the similarity exceeds a preset threshold, if the similarity exceeds the preset threshold, a second constructed name is generated based on the target region container and sub-point abbreviation after deleting the partitioning words, and this second constructed name replaces the sub-point name in the point of interest data. The preset threshold is a pre-defined critical value; for example, a preset threshold of 80%. If the similarity exceeds 80%, the newly generated second constructed name is used as the sub-point name.

[0143] In a preferred embodiment of the present invention, determining a target slice container from the one or more slice containers includes:

[0144] Determine the inclusion relationship between the one or more slice containers, and determine the innermost slice container from the one or more slice containers according to the inclusion relationship, as the target slice container.

[0145] The innermost segment container is the smallest segment container among all the segment containers to which the child point belongs. This is achieved by first determining the inclusion relationships among all the segment containers to which the child point belongs, and then selecting the innermost segment container as the target segment container based on these relationships. Specifically, the innermost segment container can be determined in the following two ways:

[0146] Case 1: If the area containers are contained within each other, the contained area container is the innermost area container. Case 2: If the area containers are intersecting, the intersecting part must occupy more than a certain percentage of the area of ​​one area container (e.g., 80%) and no more than a certain percentage of the area of ​​the other area container (e.g., 20%). The area container that meets these conditions is the innermost area container.

[0147] The embodiments of the present invention will be explained and illustrated below with three examples.

[0148] [First scenario: The sub-point's alias contains the name "target region container + sub-point abbreviation"] For example... Figure 4 As shown, 401 is the original location of the sub-point "Jiaming Tongcheng - South Gate"; the area enclosed by 402 is the innermost area container of the sub-point "Jiaming Tongcheng F District"; the area enclosed by 403 is the main point name container "Jiaming Tongcheng".

[0149] (1) Assume that the original sub-points in the interest point data are named: Jiaming Tongcheng-South Gate.

[0150] (2) Name container of the main point: Jiaming Tongcheng;

[0151] (3) Abbreviation of sub-point: South Gate;

[0152] (4) The area container to which the sub-point belongs: Jiaming Tongcheng, Jiaming Tongcheng F area;

[0153] (5) The innermost region container to which the sub-point belongs (i.e., the target region container): Jiaming Tongcheng F District;

[0154] (6) Reconstruct the sub-point name using the innermost region container to which the sub-point belongs: Jiaming Tongcheng F District - South Gate;

[0155] (7) The alias of the sub-point contains exactly the reconstructed sub-point name: Jiaming Tongcheng F District - South Gate;

[0156] (8) Determine whether the directional words in the newly constructed sub-point name meet the directional conditions of the directional region to which the sub-point belongs in the innermost area container, that is, determine whether “Jiaming Tongcheng F District - South Gate” belongs to the southern region of the area container “Jiaming Tongcheng F District”.

[0157] (9) If both (7) and (8) above are true, then the newly constructed sub-point name is determined as the sub-point name, that is, “Jiaming Tongcheng F District - South Gate” is determined as the new sub-point name.

[0158] [Second scenario: After using a synonym replacement for the sub-point abbreviation, the name resulting from "region container name + the sub-point abbreviation after the synonym" happens to be an alias for the sub-point.] For example... Figure 5 As shown, 501 is the location of the original sub-point "Ruidu International - West Gate"; the area enclosed by 502 is the innermost area container of the sub-point "Ruidu International South Area"; the area enclosed by 503 is the main point name container "Ruidu International";

[0159] (1) Assume that the original sub-points in the point of interest data are named: Ruidu International-West Gate;

[0160] (2) Main point name container: Ruidu International;

[0161] (3) Sub-point abbreviation: West Gate;

[0162] (4) The area container to which the sub-point belongs: Ruidu International, Ruidu International South Area;

[0163] (5) The innermost area container to which the sub-point belongs: Ruidu International South Zone;

[0164] (6) Reconstruct the sub-point name using the innermost region container to which the sub-point belongs: Ruidu International South Zone - West Gate;

[0165] (7) The newly constructed “Ruidu International South District - West Gate” cannot be found from the aliases of the sub-points;

[0166] Then, the abbreviations for sub-points are expanded, including expansion of direction names and gate numbers, namely: Southwest Gate, Northwest Gate, West 1 Gate, West 2 Gate, ... West N Gate, Southwest 1 Gate, Southwest 2 Gate, ... Southwest N Gate, Northwest 1 Gate, Northwest 2 Gate, ... Northwest N Gate. Then, the name of the innermost area container to which the sub-point belongs is combined with the newly expanded abbreviations to form new names. For example, it can be combined into: Ruidu International South District - Southwest Gate, Ruidu International South District - Northwest Gate, Ruidu International South District - West 1 Gate, Ruidu International South District - West 2 Gate, ... Ruidu International South District - Northwest N Gate;

[0167] (8) Match the reconstructed sub-point name and the sub-point alias. As an example, assume that the reconstructed sub-point name "Ruidu International South District - Southwest Gate 3" exists in the sub-point alias.

[0168] (9) Determine whether the directional words in the newly constructed sub-point name meet the directional conditions of the directional area to which the sub-point belongs in the innermost area container, that is, determine whether “Ruidu International South District - Southwest Gate 3” belongs to the southwest area of ​​the area container “Ruidu International South District”.

[0169] (10) If both (8) and (9) above are true, then the newly constructed sub-point name is determined as the sub-point name, that is, “Jiaruidu International South District - Southwest Gate 3” is determined as the new sub-point name.

[0170] [Third scenario: The name container has no partitions (stages), but the region container has partitions (stages). For region containers and name containers with high name similarity, replace the original sub-point names with the region name + sub-point abbreviation.] For example... Figure 6 As shown, 601 is the location of the original sub-point "Jintian Park - East Gate"; the area enclosed by 602 is the innermost area container of the sub-point "Jintian Park - North Area"; and the area enclosed by 603 is the main point name container "Jintian Park".

[0171] (1) Assume that the original sub-points in the point of interest data are named: Jintian Park - East Gate;

[0172] (2) Main point name container: Jintian Park;

[0173] (3) Abbreviation of sub-point: East Gate;

[0174] (4) Sub-point area container: Jintian Park, Jintian Park-North Area;

[0175] (5) The innermost area container to which the sub-point belongs: Jintian Park - North Area;

[0176] (6) Reconstruct the sub-point name using the innermost area container to which the sub-point belongs: Jintian Park-North Area-East Gate;

[0177] (7) No alias record was found in the sub-point, so the above "first case" and "second case" cannot be used;

[0178] (8) Remove the zoning or phase information from the area container: "Jintian Park - North District" becomes "Jintian Park" after removing the zoning information "North District";

[0179] (9) Calculate the similarity between the name of the area container after removing the partition information and the name of the main point container. If the similarity exceeds 80%, the newly constructed name is used as the recommended name of the sub-point: that is, calculate the similarity between "Jintian Park" and "Jintian Park". If the similarity is 100% (exceeding 80%), then "Jintian Park-North District-East Gate" is used as the name of the new sub-point.

[0180] (10) If the newly recommended sub-point name contains a directional word, further determine whether the directional word in the newly recommended sub-point name meets the directional conditions of the directional area to which the sub-point belongs in the innermost area container, that is, determine whether "Jintian Park-North District-East Gate" is in the eastern area of ​​"Jintian Park-North District".

[0181] (11) If both (9) and (10) above are true, then the newly constructed sub-point name is determined as the sub-point name, that is, "Jintian Park-North District-East Gate" is determined as the new sub-point name.
