    September 2010 - Present

    Sigimera Ltd. was founded in 2013 and is the company behind the project with the same name (founded in 2010). Sigimera consists currently of two major platforms. The first is the Crises Information Platform with the purpose to crowd-source the information sharing part in and around crises. It is an ambitious project that combines information about crises - currently natural disasters - from official authorities with information from the community. The major goal is to help people in and around crises with relevant and easy accessible information. Additional the Sigimera Platform provides a REST API that could be used by developers to create crises software.
    The second is Sigimera Fundraising. This service helps small and medium enterprises, but also private persons, to manage their fundraising campaigns. Additional it improves trust in the beneficiary, allows the granular tracking of financial streams and helps to optimize campaigns.

    This paper conducts a literature study to answer the question if a decentralized ledger (blockchain), as used in Bitcoin and other alternative money like informational commodities, allows scaling of the Economy of Giving from small communities to a global scale. It starts by introducing the concept of Economy of Giving and the technology behind decentralized ledgers. It answers then the non obvious question how both concepts can be combined and explains the resulting implications. Finally, it concludes with an analysis why such a combination is favourable and gives an outlook to future work that is needed to make this new model a success.

    In this paper the transition of HPC from su-percomputers and clusters to the cloud is outlined. After a short introduction the term HPC is defined. On the base of HPC application requirements the paper describes why the first generation cloud is not suitable for HPC and how the major players in the cloud space try to fix that by going back to the cluster architecture. The paper concludes with an outlook to future development.

    In the past decades, the Web has become one of the most important mediums for the buying and selling of products or services online, leading to the development of a very prolific industry known as e-Commerce. Particularly in the Tourism domain, e-Commerce is becoming the dominant means for selling and buying touristic services. Trips, holidays and business travels are increasingly being bought and sold online. 55% of all travel bookings in Europe were made online in 2011, with an increase of 15% compared to 2010. Considering the latest developments of the Web in the direction of user-generated content, information sharing, online collaboration and social media, all gathered under the umbrella term of Web 2.0, the number of channels interacting with potential tourist and touristic offers have drastically increased. In this day and age, the development of successful e-Commerce solutions not only requires the infrastructure for businesses worldwide to sell their products and services to customers, but more importantly, the ability to communicate and engage with existing and new customers in order to increase the visibility, reputation and in the end, the revenues of these businesses. In this paper, we introduce the Seekda Social Agent (SESA), an ongoing effort which aims at delivering a platform that will help businesses in the tourism domain in dealing with the challenge of improving and maintaining their communication needs in order to engage with their customers in a proper and timely manner, and to effectively and efficiently support value exchange. Our solution integrates various social media channels including Facebook, Twitter, LinkedIn, YouTube and Flickr, disseminates information items with one click through a multitude of channels, shows feedback collected from customers, and supports engagement and value exchange through a multitude of on-line interaction possibilities based on the use of semantic technology.

    The number of online services is growing dramatically. Nowadays they can be semantic or Web 2.0 based, for fixed or mobile device consumption, end-user or provider created, oriented on specific user groups, social networks, etc. Therefore, selection and recommendation of services for the end users on the basis of the service and user data becomes a challenge, and conventional keyword-based information retrieval are no longer sufficient. Here we present an approach for effective selection and recommendation of heterogeneous online services, combining natural language based information retrieval techniques and analysis of semantic annotation, community-generated Web 2.0 type content and location awareness data.

    The European Union's vision of leveraging the current freight activities to actual e-freight paperless procedures is materialised in the scope of the e-freight project ( One of the crucial parts in the e-freight framework is the establishment of a solid interoperability base on which the different stakeholders would be able to flawlessly communicate and exchange data (i.e. requests, offers, directives etc.). This paper outlines a proposed approach, which could facilitate the trade and transport objectives in the EU regarding the improvement of the existing information exchange procedures and interoperability between the different messaging standards of the stakeholders.

    In the past several decades, the internet, and especially the Web, have become extremely important sources for the planning and booking of business travel, flights, and holidays. In 2012, around one third of all travel bookings worldwide were made on-line, a figure which has steadily increased over the last few years and is predicted to continue to rise in the years to come. Obviously, services targeting tourists will only be used if properly visible, accessible, and bookable through these channels. The latest Web developments in the direction of user-generated content, information sharing, on-line collaboration and social media, have drastically increased the number of channels offering the opportunity to interact with potential tourists and book touristic offers. In addition to semi-structured information sources, data centric channels (e.g. Linked Open Data), on-line services as well as mobile channels provide a significant andgrowing potential to present and access travel deals. Data centric channels provide machine-processable information such as mountain bike routes or public transport schedules; online services allow the booking of ski passes, restaurants, etc; mobile channels, which differ interms of types of devices and operating systems, bring new opportunities for tourism enterprises to advertise and access their services, as well as to engage with their customers. Theneed for ubiquitous access, interaction and bookability of tourist services is evident, including core services (e.g. booking accommodation) and enhanced services such as those composed of both core and added value services (e.g. booking accommodation and then ski passes). In general, the key challenge involves making tourism and travel-related services easy to find and bookable through a multitude of semi-structured data and mobile channels. This requires supportin multichannel booking in order to increase Web traffic, generate higher yield management over heterogeneous channels (with particular constraints), and help support channels through offering little to no external booking fees, and thus optimizing pricing and revenues. Furthermore, all of these channels should be accessible and consumable on mobile devices, as this is where most bookings are expected to be made in the future. In this paper, weintroduce an approach for the hospitality industry that will enable communication, collaboration and value exchange (i.e. booking) of users (i.e. tourists) through a multitude of on-line and mobile interaction possibilities based on the use of semantic technology.
