Breadth and depth in research on health disparities: commentary on the work of Nancy Krieger 总被引：1，自引：1，他引：0
Ellen K. Cromley 《GeoJournal》2009,74(2):115-121
Geocoding and spatial analysis of data describing populations and health events are important methods in health social science
now carried out using GIS technology. This commentary considers Nancy Krieger’s work on health disparities in light of the
various ways individuals and organizations use geocoded population and health data: analyzing spatial patterns of health and
disease including health disparities, aggregating data spatially, assessing health status of individuals based on characteristics
of aggregates, modeling neighborhood contextual factors affecting health, designing observation and intervention studies,
and delivering health interventions and services. The extent to which her work addresses each of these purposes is considered.
The strengths and limitations of the research including choice of spatial analytic units and techniques as reported in the
published work are discussed. Krieger’s work, with her colleagues, has used standard methods of spatial analysis to raise
the profile of GIS and spatial analysis in the public health community. 相似文献

ArcGIS中地理编码方法的改进 总被引：2，自引：0，他引：2
城市管理部门对空间数据与非空间数据共享整合的要求日益迫切,急需利用地理编码技术把空间数据和非空间数据联系起来。但是由于中国的地名、地址体系异常复杂等原因的存在,使得地理编码技术没有国外成熟,应用也没有国外广泛。针对上述问题,笔者提出了解决ArcGIS中组合定位器不支持中文等问题的一种解决方案,并且通过应用于上海市青少年管理系统,提出了关于如何提高地址匹配成功率的几点建议。 相似文献

ABSTRACT The analysis of geographically referenced data, specifically point data, is predicated on the accurate geocoding of those data. Geocoding refers to the process in which geographically referenced data (addresses, for example) are placed on a map. This process may lead to issues with positional accuracy or the inability to geocode an address. In this paper, we conduct an international investigation into the impact of the (in)ability to geocode an address on the resulting spatial pattern. We use a variety of point data sets of crime events (varying numbers of events and types of crime), a variety of areal units of analysis (varying the number and size of areal units), from a variety of countries (varying underlying administrative systems), and a locally-based spatial point pattern test to find the levels of geocoding match rates to maintain the spatial patterns of the original data when addresses are missing at random. We find that the level of geocoding success depends on the number of points and the number of areal units under analysis, but generally show that the necessary levels of geocoding success are lower than found in previous research. This finding is consistent across different national contexts. 相似文献

Chinese address segmentation is a serious challenge in geographic information system geocoding. Most previous studies have relied on predefined gazetteers without considering the information contained by a raw address corpus. In this paper, a hybrid method employing both rule-based and statistical methods is proposed for Chinese address segmentation without a predefined gazetteer. This approach utilizes statistical methods to extract address information from a raw address corpus and a rule-based method to segment Chinese addresses. Two typical statistical methods and their combinations with rule-based methods are compared with the hybrid method in an experiment involving approximately 460,000 address items in Shenzhen City, China. The experimental results indicate that the proposed method achieves an F-score of over 0.8, which is better than those of existing methods, thus validating the proposed method. 相似文献

ABSTRACTAddress matching is a crucial step in geocoding, which plays an important role in urban planning and management. To date, the unprecedented development of location-based services has generated a large amount of unstructured address data. Traditional address matching methods mainly focus on the literal similarity of address records and are therefore not applicable to the unstructured address data. In this study, we introduce an address matching method based on deep learning to identify the semantic similarity between address records. First, we train the word2vec model to transform the address records into their corresponding vector representations. Next, we apply the enhanced sequential inference model (ESIM), a deep text-matching model, to make local and global inferences to determine if two addresses match. To evaluate the accuracy of the proposed method, we fine-tune the model with real-world address data from the Shenzhen Address Database and compare the outputs with those of several popular address matching methods. The results indicate that the proposed method achieves a higher matching accuracy for unstructured address records, with its precision, recall, and F1 score (i.e., the harmonic mean of precision and recall) reaching 0.97 on the test set. 相似文献

To put on the map: according to the Oxford English Dictionary, whatever is so placed occupies “an important or prominent position” and is “of
some account or importance.” In this brief commentary, I take the opportunity to reflect on several articles by medical/health
geographers and others regarding our Public Health Disparities Geocoding Project and my research, as a social epidemiologist, on the myriad ways racism can harm health. In both cases, my work on these topics
has been motivated by my desire, starting a quarter of a century ago, to put health inequities on the map: as a topic of public
concern, research, and action. The insightful and informative points and questions raised by the geography-oriented articles
underscore the importance of bringing the best of our respective disciplinary insights and expertise to illuminate the profound
connections between social justice and public health, between our bodily truths and the body politic, so as to further the
goal of embodying equity––in an ecologically sustainable world. 相似文献
