Scientific articles often contain relevant geographic information such as where field work was performed or where patients were treated. Most often, this information appears in the full-text article contents as a description in natural language including place names, with no accompanying machine-readable geographic metadata. Automatically extractin...

Cancers arise from the accumulation of somatic genome mutations, which can be influenced by inherited genomic variants and external factors such as environmental or lifestyle-related exposure. Due to the heterogeneity of cancers, precise information about the genomic composition of germline and malignant tissues has to be correlated with morphologi...

Defining and identifying duplicate records in a dataset is a challenging task which grows more complex when the modeled entities themselves are hard to delineate. In the geospatial domain, it may not be clear where a mountain, stream, or valley ends and begins, a problem carried over when such entities are catalogued in gazetteers. In this paper, w...
Article
In scientific communication, ambiguities in term usage can go unnoticed due not only to the distance between reader and writer, but also to the existence of highly specialized scientific subcommunities. This commentary therefore aims at raising awareness about the use of terms that have different meanings within different hydrological subcommunitie...

How do people perceive landscapes? What elements of the landscape do they identify as characteristic of a landscape? And how can we arrive at descriptions, and ultimately representations that better reflect people’s notions of landscapes? In this study, we collected landscape descriptions from five landscape types at 10 study sites in Switzerland....
Conference Paper
We investigate gazetteer matching between natural features in Switzerland. We produce a gold standard dataset for a subset of features from 8 natural feature types in GeoNames aligned with their corresponding match(es) in SwissNames3D, an authoritative gazetteer. Based on this dataset, we comment on feature type alignments between the two resources...
Conference Paper
Explicitly linking text documents to geographical space is an important processing step for applications such as map visualization, spatial querying, and placename disambiguation. In this work, we present a proof-of-concept processing pipeline to generate spatial footprints for a spatially-rich, manually-annotated corpus of hiking blogs. We present...
Article
Gazetteers are important tools used in a wide variety of workflows that depend on linking natural language text to geographical space. The spatial properties of these data sources, such as coverage, balance, and completeness, affect the performance of common tasks such as geoparsing and geocoding. However, little attention has focused on how these...

Gazetteers are playing a central role in the current data revolution as key tools to link content to geographical space. However, their geographies and idiosyncrasies are poorly understood despite their potential to worsen application outcomes and information inequalities. In this study, we analyze two open gazetteers, GeoNames and the Getty Thesau...

... Also by separating functional processing and structural processing, precision and recall could be improved. Parsing for obtaining geographic information has been presented in [14]. This technique employs fully automatic pipe line model. ...
... Cancers result from the cumulative effects of gene mutations that eventually undermine cellular reproductive controls, such as contact inhibition. When such mutations are found to be caused by external factors, the cancers may be classified as environmental (Carrio-Cordo et al., 2020). Nearly all cancers are non-communicable diseases (NCDs). ...
... The confusion matrix diagram is presented in Figure 4. Precision and recall are the most often used metrics for gauging the effectiveness of DL models. Precision is the ratio of the technique's correct or wrong estimates, whereas recall refers to the percentage of the total number of true matches and the total number of positive matches [31]. These metrics are showcased in the form of equations as follows [32,33]. ...
... A widely accepted list of definitions would avoid confusion and facilitate successful interaction and collaboration. Furthermore, we need to clarify hydrological terms for peers from other disciplines, stakeholders, and a general audience (Brunner et al., 2018) to facilitate easier communication, understanding, and analysis. ...
... Although not explored in this thesis, the advantage of crowdsourced data is that it provides a lot of information on these more relational interactions with nature (Langemeyer and Calcagni, 2022). In other research, for example, Flickr images and the associated text have been used to understand cultural properties such as digital identities (Davies, 2007) and peoples' sense of place (Jenkins et al., 2016;Wartmann et al., 2018). These rich new data sources can therefore also support measures of this more relational NCP at the generalising-level. ...
... • We use open datasets and, for a subset of gazetteer records, a publicly available annotated gold standard (Acheson et al. 2017b), thus enabling future work to be directly comparable. • We implement machine learning methods for the matching task and compare these to rule-based methods. ...
... This has been achieved through initiatives such as Humanitarian OpenStreetMap Team (HOT) Tasking Manager0F , Missing Maps1F and YouthMappers2F . Gazetteers collect and make available place names and their coordinates (39) increasing the quantity and quality of geocoded place-names (40 and its sentinel satellites, The National Aeronautics and Space Administration (NASA) and the US Geological Survey3F (41). As changes were happening in Kenya's MHFL and increased geocoding platforms, in 2011, District Health Information System 2 (DHIS2) (42)-an open-source, web-based platform used as a health management information system was launched in Kenya (43). ...
... Ahlers (2013) conducted a broader examination of data quality in GeoNames, identifying anomalies and quality indicators for populated places in Central America, Germany, and Norway. Looking at both GeoNames and TGN, De Sabbata andAcheson (2016)quantitatively compared their coverage for all features and populated places in Great Britain, finding the datasets less detailed and less balanced than national mapping agency data. Although these studies have revealed that coverage in these products is unbalanced even within individual countries, the overall picture remains unclear since to date, an in-depth systematic global analysis, looking across country boundaries and at a range of feature types across gazetteers, has not been carried out. ...
