Usage of Internet technologies by touristic service providers

Planet Data - Wed, 06/11/2014 - 10:19
Authors: Dieter FenselYear: 2014Presentation Date: Tuesday, 10 June, 2014Presented at: FORTH

Communicating straight with customers, in an efficient and effective manner is still a desideratum for small, medium and large companies alike. With the rapid development of ICT technologies, including Internet, Web-based communication, and recently Social Media, the number of possibilities to interact directly with customers has grown event larger. For small and medium companies in general and those in the touristic industry in particular, direct communication with customers has been always seen as an enabler for massive direct sales. However, these expectations are still to be fulfilled. In this talk we analyze the causes of this failure and propose a solution on how effective and efficient communication for touristic industry should be realized. We perform an empirical analysis of the usage pattern of Internet technology in the touristic domain. We introduce first the challenges faced nowadays by touristic service providers in terms of online and mobile booking, commission payments and social media. We then have a look at key technologies and communication channels that touristic service providers must use in order to be highly visible online including static, dynamic, sharing, collaboration, social media, fora, vocabularies, semantic formats, etc. We analyze the uptake of these technologies and channels by hotels, hotels chains, destinations and booking channels and point out on one hand how well intermediaries i.e. booking channels (e.g. booking.com, hrs.de, etc.) are using them, while on the other hand, touristic service providers are failing. Finally, we show how these technologies and communication channels should be used for effective direct marketing in the touristic industry by means of a real pilot developed in collaboration with the touristic association of service providers located in the city of Innsbruck and its surroundings i.e. Tourismusverband Innsbruck (TVb).

Linking Geospatial Data

Planet Data - Fri, 04/04/2014 - 16:09
Start date: Wednesday, 5 March, 2014End date: Thursday, 6 March, 2014

What are best examples of data-driven Web applications you've ever seen? The updates to Open Street Map after the Haiti earthquake? The mapping of all 9,966,539 buildings in the Netherlands? The NHS Prescription data? Things like SF Park that help you 'park your car smarter' in San Francisco using real time data? Bing maps and Google Earth?

 

All these and many, many more data-driven applications have geospatial information at their core. Very often the common factor across multiple data sets is the location data, and maps are crucial in visualizing correlations between data sets that may otherwise be hidden. 

 

It's this desire to work with multiple data sets in different formats about different topics and link those with the powerful technologies used in geospatial information systems that is behind the linking geospatial data workshop.

 

How can geographic information best be integrated with other data on the Web? How can we discover that different facts in different data sets relate to the same place, especially when 'place' can be expressed in different ways and at different levels of granularity?

 

On behalf of the Smart Open Data project, the World Wide Web Consortium (W3C), in partnership with the Open Geospatial Consortium (OGC) and the OGC GeoSPARQL Standards Working Group, the UK Government Linked Data Working Group, Google and Ordnance Survey, invite you to share your experiences, successes and frustrations in using GI.

 

The workshop is open to all and will take place at Campus London on Wednesday 5th - Thursday 6th March, 2014.

Tutorial on RDF-Stream Processing at ESWC 2014

Planet Data - Fri, 04/04/2014 - 16:08
Start date: Sunday, 25 May, 2014End date: Thursday, 29 May, 2014

The tutorial provides a comprehensive view of the RDF-Stream Processing (RSP) research area. It consists of four parts. The first one introduces the RSP basic concepts: RDF streams to represent temporally-ordered sequence of data items; continuous SPARQL extensions to query RDF streams, and RSP engines to execute continuous query answering over RDF streams. The second part presents the available RSP engine implementations. It starts with an overview on the existing RSP engines, highlighting similarities and differences among them. Next, two existing implementations are analysed in depth: C-SPARQL and SPARQLstream. The third part is a hands-on session where the attendees learn how to (1) use the three presented RSP engines presented above and (2) let the systems interact among them. Finally, the fourth part of the tutorial provides an overview on RSP-related topics: RSP engine benchmarking, stream reasoning and real-world deployments. The tutorial closes with a discussion on the open challenges and the research problems of this research field.

Exploring RDF/S Evolution using Provenance Queries

Planet Data - Fri, 04/04/2014 - 15:26
Year: 2014Publication Date: Friday, 28 March, 2014Published in: 1st International Workshop on Exploratory Search in Databases and the Web, Co-located EDBT/ICDT 2014Authors: Haridimos Kondylakis, Dimitris PlexousakisAbstract: 

The evolution of ontologies is an undisputed necessity in current research community. The problem of understanding this evolution is a fundamental problem as, based on this understanding, maintainers of depending artifacts need to take a decision about possible changes. Moreover, as ontologies are often developed by several ontology engineers, it is also important for them to understand what changes have been made by each other. Recent research focuses on just identifying and presenting the changes from one ontology version to another. In this paper, we argue that this is not enough and that we need more fine-grained methods for understanding how the ontology evolved. To this direction, we present a module, named ProvenanceTracker, which gets as input the list of changes between two or more RDF/S ontology versions and can answer fine-grained provenance queries about ontology resources. Our module can identify when a resource was created and how. The sequence of changes that led to the creation of that specific resource can be identified and presented to the user. We evaluate the time complexity of our approach and show that it can possibly reduce the human effort spent on understanding ontology evolution.

Hippalus: Preference-enriched Faceted Exploration

Planet Data - Fri, 04/04/2014 - 15:21
Year: 2014Publication Date: Friday, 28 March, 2014Published in: 1st International Workshop on Exploratory Search in Databases and the Web, Co-located EDBT/ICDT 2014Authors: Panagiotis Papadakos, Yannis TzitzikasAbstract: 

In this work we describe and evaluate Hippalus, a system that offers exploratory search enriched with preferences. Hippalus supports the very popular interaction model of Faceted and Dynamic Taxonomies (FDT), enriched with user actions which allow the users to express their preferences. The underlying preference framework allows expressing preferences over attributes (facets), whose values can be hierarchically valued and/or multi-valued, and offers automatic conflict resolution. To evaluate the system we conducted a user study with a number of tasks related to a "car selection" scenario. The results of the comparative evaluation, with and without the preference actions, were impressive: with the preference-enriched FDT, all users completed all the tasks successfully in 1/3 of the time, performing 1/3 of the actions compared to the plain FDT. Moreover all users (either plain or expert) preferred the preference enriched interface. The benefits are also evident through various other metrics.

Geospatial Data Integration with Linked Data and Provenance Tracking

Planet Data - Fri, 04/04/2014 - 15:14
Year: 2014Publication Date: Saturday, 3 May, 2014Published in: Linking Geospatial Data, London, W3C/OGCAuthors: Andreas Harth, Yolanda GilAbstract: 

We report on our experiences with integrating geospatial datasets using Linked Data technologies. We describe NeoGeo, an integration vocabulary, and an integration scenario involving two geospatial

datasets: the GADM database of Global Administrative Areas and NUTS, the Nomenclature of Territorial Units for Statistics. We identify the need for provenance to be able to correctly interpret query results over the integrated dataset.

Combining Reasoning on Semantic Web Metadata

Planet Data - Fri, 04/04/2014 - 15:07
Year: 2014Publication Date: Saturday, 1 March, 2014Published in: supporting ECAI’14 submissionAuthors: Loris Bozzato, Luciano Serafini Abstract: 

As the amount of available linked data expand and the number of related applications increases, the management of aspects such as provenance and access control of such data begin to become an issue. Current approaches do not provide sufficient support for automatic reasoning over different metadata and their possible interdependencies. MetaReasons is a framework that supports the representation of metadata in a logical formalism and consequently to support automated reasoning on metadata. Different types of metadata, such as data-provenance and accessibility-restrictions are represented as distinct meta-theories, and dependencies between types of metadata are represented by rules between different meta-theories. In this paper we present the logic based definition of the MetaReasons framework and two examples of meta-theories for provenance and access control. Moreover, we propose a materialization calculus for concrete forward reasoning on the two aspects.

EXPERIMEDIA @ The Future Internet Assembly, 8-10th May

Experimedia - Wed, 04/17/2013 - 16:21
The EXPERIMEDIA project will be at the Future Internet Assembly in Dublin, May 8-10th. We have a large booth in the Hands on FIRE exhibition shared with the related projects 3D-LIVE and STEER. We are also running a session on Linking user populations to novel networks in Future Internet research programmes on Thursday. With our second Open Call coming up it is a great opportunity to come and talk to us about getting your ideas funded.MEDIAConnect Demonstration The MEDIAConnect experiment is finding out whether people find Augmented Reality displays useful for accessing information. MEDIAConnect is deployed in Schladming, the Austrian ski resort that recently hosted the FIS World Ski Championship 2013. The experiment is investigating the Quality of Experience for tourists using a mobile augmented reality application. By pointing their tablet or phone at large panorama posters of the ski slopes located at the ski lifts they can view additional dynamic content such as weather conditions, ski lift states (open or closed) and photos of points of interest. This application aims to allow skiers to better plan their day of skiing and spot new areas of interest whilst at the ski station. See for yourself: come and try MEDIAConnect at our stand. Weightlifting Demonstration Become a Future Internet Athlete!  Can you lift the weights better than an Olympian?When lifting our (very light) weights you will be tracked in 3D and given a score for the leader board which is then Tweeted for your friends to enjoy. Meanwhile the score, Quality of Service data from the 3D tracking, your emotional feedback and analysis of social network activity is all fed into the Experiment Content Component database to help an experimenter understand the usage and impact of the system. This is a fun extension of an experiment being undertaken at CAR, the high-performance athletics training facility in Barcelona. Instant feedback is provided to the athletes and coach regarding the speed, position and balance of a lift and we may also investigate the pros and cons of sharing training performance data online with an athlete’s social circle. Come and see if you are the best and learn about experimentation in EXPERIMEDIA.Linking user populations to novel networks in Future Internet research programmes As one of the FIA working sessions on Thursday, we will be leading a discussion on how we can engage users in Future Internet research and experimentation. Using case studies from EXPERIMEDIA, STEER, 3D-LIVE and FI-CONTENT we will explore the following questions: What approaches exist and what is applicable in what situation? How does user participation change at different phases of the RTD lifecycle? How can we scale user participation from trials to industrialization and what does this mean for qualitative and quantitative assessment? How is user participation being addressed in the FIRE and FI-PPP programmes and what can be done to improve it?
