用户推文中的地名信息是定位推特用户的重要基础数据之一,但现有推特用户定位方法提取的地名在数量和可靠性方面均存在欠缺,影响了用户定位准确性。提出基于单点地名匹配和局部地名筛选的推特用户定位方法。设计一种基于地名位置聚集度的地名类型判别算法,根据位置分布的聚集程度构建单点地名库,获取推文中更多可靠地名;提出一种基于用户位置聚集度的局部地名筛选算法,分别以地名经纬度和用户平均经纬度为中心,计算用户位置聚集度,筛选更高聚集度、更可靠的局部地名;基于用户社交关系、用户对地名的提及关系构建用户-地名异构图,并利用图表示学习和神经网络定位用户。基于常用公开数据集GEOTEXT和TW-US进行大量用户定位实验,并与HGNN、ReLP、GCN等9种现有推特用户位置推断典型方法进行了对比,结果表明,所提方法对推特用户的位置推断准确率具有明显优势,相比9种现有典型方法,在GEOTEXT数据集上,平均误差降低了7.3~342.8 km,中位数误差降低了2.4~354.4 km,大地区级定位准确率提高了1.3%~26.3%;在TW-US数据集上,平均误差降低了8.6~246.6 km,中位数误差降低了5.7~149.7 km,大地区级定位准确率提高了1.5%~20.5%。
The availability of accurate toponyms in user tweets is crucial for geolocating Twitter users.However
existing methods for locating Twitter users often suffer from limited quantity and reliability of acquired toponyms
thus impacting the accuracy of user geolocation.To address this issue
a twitter user geolocation method based on single-point toponym matching and local toponym filtering was proposed.A toponym type discriminating algorithm based on the aggregation degree of locations of the toponym was designed.In the proposed algorithm
a single-point toponym database was generated to provide more reliable toponyms extracted from tweets.Then
according to a proposed local place name filtering algorithm based on the aggregation degree of user location
the aggregation degree of user location centered on the longitude and latitude of toponyms and the average longitude and latitude of users were calculated.This process helped in extracting local toponyms with a high aggregation degree
which enhances the reliability of toponyms used in geolocation.Finally
a user-toponym heterogeneous graph was constructed based on user social relationships and user mentions of toponyms
and users were located by graph representation learning and neural networks.A large number of user geolocation experiments were conducted based on two commonly used public datasets in this field
namely GEOTEXT and TW-US.Comparisons with nine existing typical methods for Twitter user geolocation
including HGNN
ReLP
and GCN
demonstrate that our proposed method achieves significantly higher geolocation accuracy.On the GEOTEXT dataset
the average error is reduced by 7.3~342.8 km
the median error is reduced by 2.4~354.4 km
and the accuracy of large area-level geolocation is improved by 1.3%~26.3%.On the TW-US dataset
the average error is reduced by 8.6~246.6 km
the median error is reduced by 5.7~149.7 km
and the accuracy of large area-level geolocation is improved by 1.5%~20.5%.
