Tagging is one of the defining characteristics of Web 2.0 services and platforms. Tagging techniques allow users to collectively annotate, classify and categorize content. Social tagging systems are a mix of two standards: one based on user actions and other based in the system architecture that defines the rules and the relationship between users and resource tags.

Geotagging moving video
Hoo, Chang Sheng · DR-NTU (Nanyang Technological University) · 2017
Today, digital video technologies have advanced and made it simple to use through smartphones. Sharing of video contents online have been increasingly popular, and in times of incident, these are often essential evidences of crime to the investigation. However, there posed challenges to identify relevant video contents due to the insufficient information inputs. This report presents an incident sharing system called Geo-Recorder that can be installed on a smartphone and view its shared content on a web browser. Geo-Recorder capture essential inputs by leveraging what the smartphone have and formats the data into relevant information. The incident sharing system is made up in two parts, a developed Android application installed on a smartphone that record and upload incident videos, and a web application that served as a visualization representation of these uploaded videos.

Geotagging the Self
Milton Fernando González Rodríguez · 2023
This chapter argues that a transmuted/transmitted locatable self has become central in the construction of personal identity on transmediatised platforms. Sharing one’s whereabouts via text messages (e.g., WhatsApp), providing accurate position information about one’s photos (e.g., Facebook), and allowing one’s gallery and precise location to be displayed as part of a grid of potential partners (e.g., Tinder) are examples of a self that has become geographically locatable and virtually relatable. A need for social connection has driven people to create online identities that reflect intimate aspects of their spatial offline reality. On-hand presence and information about location enhances the credibility, accessibility and legitimacy of individuals’ virtual identities. Self becomes practical (e.g., sharing one’s address), approachable (e.g., location entwined with compatibility and availability on dating sites), and public (e.g., checking into a location on social networks). In varying ways and to varying extents, the creation of a mediatic, relatable virtual identity relies on the notion that the internal (offline) and external (online) self can be mapped, pinned down in terms of figures of longitude and latitude, and revealed through conflictual paradoxes that denote its borders. This occurs even if carefully engineered, interactive and distinctively mediatised identities become recognizable for their sense of futility, briefness and commercialization. Ultimately, this chapter sheds light on the ways in which space plays a role in the construction of virtual identity across mobile/social media platforms.

Privacy paradox on geotagging
Deniz Kılıç · Utrecht University Repository (Utrecht University) · 2017
Nowadays, social media applications are embedded with geotag features, and users share their experiences of places with other people online to express themselves. Users post their text messages, photos and videos online and geotag them to share the location of the undertaken activity. Geotag features enhance the user experience, but also introduce privacy related threats and issues. Social media users place themselves at a greater risk for identity theft or cyber stalking by disclosing their whereabouts online. Academic literature suggests social media users are concerned about their online and location privacy, and also have a cautious attitude towards sharing personal and location information. However, users keep sharing their location information with fellow users and application\nservices despite their concerns. This dichotomy between concern and disclosure behaviour is known as privacy paradox.\n\nThis thesis investigates if privacy paradox applies to geotagging behaviour on social media. With the help of an online survey, 184 social media users are questioned about their geotagging activities, their attitude towards re-use of location information and the accessibility of their location information by fellow users. In addition, their concerns regarding location privacy are also examined.

Multifaceted Geotagging for Streaming News
Lieberman, Michael David · Digital Repository at the University of Maryland (University of Maryland College Park) · 2012
News sources on the Web generate constant streams of information, describing the events that shape our world. In particular, geography plays a key role in the news, and understanding the geographic information present in news allows for its useful spatial browsing and retrieval. This process of understanding is called <italic>geotagging</italic>, and involves first finding in the document all textual references to geographic locations, known as <italic>toponyms</italic>, and second, assigning the correct lat/long values to each toponym, steps which are termed <italic>toponym recognition</italic> and <italic>toponym resolution</italic>, respectively. These steps are difficult due to ambiguities in natural language: some toponyms share names with non-location entities, and further, a given toponym can have many location interpretations. Removing these ambiguities is crucial for successful geotagging. To this end, geotagging methods are described which were developed for streaming news. First, a spatio-textual search engine named STEWARD, and an interactive map-based news browsing system named NewsStand are described, which feature geotaggers as central components, and served as motivating systems and experimental testbeds for developing geotagging methods. Next, a geotagging methodology is presented that follows a multifaceted approach involving a variety of techniques. First, a multifaceted toponym recognition process is described that uses both rule-based and machine learning–based methods to ensure high toponym recall. Next, various forms of toponym resolution evidence are explored. One such type of evidence is lists of toponyms, termed <italic>comma groups</italic>, whose toponyms share a common thread in their geographic properties that enables correct resolution. In addition to explicit evidence, authors take advantage of the implicit geographic knowledge of their audiences. Understanding the local places known by an audience, termed its <italic>local lexicon</italic>, affords great performance gains when geotagging articles from local newspapers, which account for the vast majority of news on the Web. Finally, considering windows of text of varying size around each toponym, termed <italic>adaptive context</italic>, allows for a tradeoff between geotagging execution speed and toponym resolution accuracy. Extensive experimental evaluations of all the above methods, using existing and two newly-created, large corpora of streaming news, show great performance gains over several competing prominent geotagging methods.

Geotagging av platsnamn från metadata
Språkbanken Text · Språkbanken Text · 2018
Texter berikas med platsnamn (och deras geografiska koordinater) som finns i dess metadata. Detta är baserat på platsnamn som hittats genom namnigenkänning med SweNer. Geografiska koordinater letas upp i GeoNames-databasen. Denna annotation kan användas på valfria textspann och valfria attribut som innehåller platsnamn. Exempel (in English) This analysis is used with Sparv. Check out Sparv's quick start guide to get started! To use this analysis, add the following line under export.annotations in the Sparv corpus configuration file: - <text>:geo.geo_metadata # Geographical places with coordinates In order to use this annotation you need to tell Sparv where to look for the geographic metadata. If, for example, your corpus looks like this: <text author_location="Göteborg">Det var då änna bösigt i bamban!</text> and you would like to use author_location as input for your annotation you need to add the following setting to your Sparv corpus configuration file: geo: metadata_source: text:author_location For more info on how to use Sparv, check out the Sparv documentation. Example output: <text author_location="Göteborg" geo_metadata="|Göteborg;SE;57.70716;11.96679|"> <token>Det</token> <token>var</token> <token>då</token> <token>änna</token> <token>bösigt</token> <token>i</token> <token>bamban</token> <token>!</token> </text>

Geotagging accuracy in smartphone photography
Elénore Ryser, Hannes Spichiger, David-Olivier Jaquet-Chiffelle · Forensic Science International Digital Investigation · 2024
After a decade of technological advancements, digital forensic science is under increasing pressure to deliver investigative findings with a high degree of scientific rigor. The judicial community has voiced growing concerns regarding digital traces and their interpretation. This research focuses on assessing the significance of geolocation information embedded within the metadata of photographs captured using a mobile phone. In order to examine the variability in the accuracy of this geolocation metadata and identify potential external influences, images were taken at 29 different locations distributed along three distinct paths. The photographs were captured using two Samsung Galaxy S8 SM-G950F devices running on Android 8.0. Various configurations of GNSS and mobile network connections were tested, and their potential impact on the accuracy of geolocation metadata was investigated. The findings show the dependency of geolocation accuracy on the specific measurement location. This research ultimately highlights the imperative for evaluative approaches to take into account the specific characteristics of each point of interest, as opposed to leaning on broad statements about the reliability of geolocation processes in general.
