Measure of Landmark #Semantic Salience through #Geosocial Data Streams | #wayfinding #bigdata

Measure of Landmark #Semantic Salience through #Geosocial Data Streams | #wayfinding #bigdata | The urban.NET | Scoop.it
Research in the area of spatial cognition demonstrated that references to landmarks are essential in the communication and the interpretation of wayfinding instructions for human being. In order to detect landmarks, a model for the assessment of their salience has been previously developed by Raubal and Winter. According to their model, landmark salience is divided into three categories: visual, structural, and semantic. Several solutions have been proposed to automatically detect landmarks on t
luiy's insight:

Thus, we are asking the following global research question as a starting point: can we improve the urban intelligence using geosocial data generated by users of online social networks? We argue that geolocated content published on Facebook and Swarm can be exploited to enhance citizens’ spatial literacy. More precisely, check-ins datasets can be used to improve human wayfinding and smart mobility by detecting relevant semantic landmarks. Lots of research in wayfinding is done in order to enable individuals to reach as quickly as possible a desired destination, to help people with disabilities by designing cognitively appropriate orientation signs, and reduce the fact of being lost [16]. Therefore, designing tools that effectively support people’s wayfinding remains a major concern.

 

In order to defend our argument, we detail in the following section a brief state of art related to the concept of wayfinding. Then, we focus both on landmarks and systems designed for their automatic detection. The fourth section puts forward the reasons why check-ins are, in our opinion, a reliable source of information to identify semantic landmarks. More precisely, three scores based on Facebook and Swarm check-ins are suggested in order to measure landmark semantic salience. Finally, the last section of this article presents concrete examples where these scores are applied with real check-ins datasets harvested from Facebook and Foursquare APIs.

luiy's insight:

The MagicBand is the world’s largest and most diverse experiment in wearable data fashion. And like all fashion, MagicBands are classist. Automatic visits to Dataland are limited to guests who book their stay on Disney property. Those who visit Disney World for a day trip or who stay in a nearby, non-Disney owned hotel are limited to the old RFID credit card for their park tickets. But fear not, for MagicBands can be purchased for $12.95 at any Disney theme park gift shop. And everyone is allowed the opportunity to customize and personalize their MagicBands: “MagicSliders” sleeves and “MagicBandits” charms that bear the images of Disney characters can be purchased ($6.95-14.95) and attached to a MagicBand.

Anatomy of a #SmartCity | #NatureCentric #Sensors

Anatomy of a #SmartCity | #NatureCentric #Sensors | The urban.NET | Scoop.it

The 19th century was a century of empires, 20th century was a century of nation states and the 21st century will be a century of cities...

 

This outstanding infographic (courtesy of postscapes.com) begins with some information about our current state of urbanization.

 

Did you know that 1.3 million people are moving to cities each week?! It then explains the need for smart cities and delves into what is required to establish these intelligent connected environments, how the smart city may take various forms in the developing worlds and what specific technologies are necessary to achieve such grand goals in practice.

luiy's insight:

We have been grateful to the wide array of planners, architects, techies, entrepreneurs and students of the built environment who have joined us on this journey. And the ‘Smart City‘ has featured again and again, whether it be a futurologist’s insights into the bionic, nature-centric adaptable cities of the future, or an economist’s keen ideas on instilling happiness in the built environment.

There is an evolution taking place where politics, policy, technology, the environment, and the economy all intersect. This movement towards technical, empirically driven local policy making could be our saving grace.This could be the future of government.

Vast information infrastructures are creating new challenges for future cities
luiy's insight:

Agility is key


With such diverse information flying around a smart city, new technology is needed to coordinate not only this vast amount of data, but also the array of applications it may have.

 

One solution to coordinate data is an “agile network” – a system that uses new technology to automatically control and configure data. This data can also be disseminated across a number of varying devices.

 

Chinese company Huawei Enterprise is one firm helping to build these agile networks, as well as the cloud computing data centres that they hope will help make Smart Cities a reality.
