toponym resolution. Gritta et al. (b) further converted CamCoder into a geoparser by connecting it with the spaCy NER tool for toponym recognition. There also exist studies that focus on the step of toponym resolution only (Overell and Ruger, ; Buscaldi and Rosso, ; Speriosu and Baldridge, ; Ju et al., ). This thesis addresses the problem of toponym resolution. Given an ambiguous placename like Springfield in some natural language context, the task is to automatically predict the location on the earth's surface the author is referring to.

Toponym resolution is a process of assigning a toponym (place name) identified in text to a single non-ambiguous place on the earth's surface. The following sub-section briefly reviews the state-of-the-art approaches in toponym resolution relevant to the work reported in Cited by:   For the evaluation of toponym resolution, we have excluded the following examples from the dataset. (a) the most difficult to resolve toponyms such as street names, building names, festival venues and so on, which account for \(\sim 8\%\) of the total, without an entry in Geonames and often requiring a reference to additional by: 2.

Hence, techniques from supervised machine learning can be applied to improve accuracy. New classification features to improve toponym resolution, termed adaptive context features, are introduced that consider a window of context around each toponym, and use geographic attributes of toponyms in the window to aid in their correct resolution. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A key problem that arises when unstructured text is being queried is that of properly recognizing and exploiting geographical terms and entities. Here we describe a mechanism for probabilistic toponym resolution, and our experiments with the new method in the setting of the GeoCLEF queries and judgments.

Toponym Resolution, the task of assigning a location mention in a document to a geographic referent (i.e., latitude/longitude), plays a pivotal role in analyzing location-aware content. However, the ambiguities of natural language and a huge number of possible interpretations for toponyms constitute insurmountable hurdles for this task.

Text-Driven Toponym Resolution using Indirect Supervision Michael Speriosu Jason Baldridge Department of Linguistics University of Texas at Austin Austin, TX USA fsperiosu,jbaldrid [email protected] Abstract Toponym resolvers identify the specic lo-cations referred to by ambiguous place-names in text.

Most resolvers are based on. However, many proposed approaches [3,5,7,9,14,[18][19][20]23] to toponym resolution are utilizing the GeoNames, an open-source geographical databases of millions of place names [1], as its source.

Toponym resolution has the advantage over general concept resolution that user-generated, gold standard data is available, and especially in social media data. This is due to the ability to, and interest in, geotagging UGC. In addition, in a limited context it is highly likely that a given location will have only oneCited by: Toponym resolution in text: annotation, evaluation and applications of spatial grounding.

Jochen L. Leidner; Geography, Computer Science; SIGF; (First Published: 1 December ). In geographic information systems, toponym resolution is the relationship process between a toponym, i.e. the mention of a place, and an unambiguous spatial footprint of the same place.

The same geographic names have historically been used by emigrant settlers to denote their new homes, leading to referential ambiguity of place names.

Sometimes, the original name gets modified (as in "York" vs. toponym recognition (NER), we compare the precision and recall of six different NER algorithms implemented in publicly available packages. We also carry out assessments for the system's toponym resolution method, which leverages a set of heuristic rules, plus additional toponym resolution methods based on spatial hierarchies and spatial by: 7.

Both toponym resolution and document geoloca-tion involve assigning geographic reference, usu-ally latitude-longitude coordinates, to spans of text, but differ as to the size of the span. Toponym resolution involves assigning such reference to in-dividual, potentially ambiguous toponyms (e.g.

Springeld or Dallas), while document geoloca. toponym resolution, termed adaptive context features, are introduced that consider a window of context around each toponym, and use geographic attributes of toponyms in the window to aid in their correct resolution.

Adaptive pa-rameters controlling the window’s breadth and depth afford flexibility in managing a tradeoff between feature compu. Toponym resolution, also known as geoparsing, geo-grounding or place name resolution, aims to assign geographic coordinates to all location names mentioned in documents. Toponym resolution is usually performed in two independent steps.

First, toponym detection or geotagging, where the span of place names mentioned in a document is noted.Toponym resolution is the task of linking place name instances in a text with spatial footprints, given the context in which they occur. Whereas a lot of work on the evaluation of temporal resolution is ongoing (e.g.
