Trust Mining: Analyzing Trust in Collaborative Business Processes

Müller, Marcel ; Ostern, Nadine ; Koljada, Denis ; Grunert, Kai ; Rosemann, Michael ; Küpper, Axel (2021-04-26)

The ongoing digital transformation and internationalization of business processes cause a shift towards a more collaborative nature of processes. In such collaborations, different organizations execute separate parts of the process autonomously. This fragmentation leads to uncertainty regarding the correct execution of activities, the proper workflow, and data in the process flow. If organizati...

Context flow graphs: Situation modeling for rule-based proactive context-aware systems

Garzon, Sandro Rodriguez ; Louis, Bernd (2020-11-23)

A proactive context-aware system automatically adapts its user interface to the user’s situational needs. This is achieved by continuously capturing the environmental properties, reasoning upon the context, and detecting situations where unsolicited adjustments are helpful or notifications informative. If the characteristics of those situations are well known in advance, their occurrence can be...

MobRec — Mobile Platform for Decentralized Recommender Systems

Beierle, Felix ; Egger, Simone (2020-10-07)

Recommender systems recommend new movies, music, restaurants, etc. Typically, service providers organize such systems in a centralized way, holding all the data. Biases in the recommender systems are not transparent to the user and lock-in effects might make it inconvenient for the user to switch providers. In this paper, we present the concept, design, and implementation of MobRec, a mobile pl...

Sensafety: Crowdsourcing the Urban Sense of Safety

Rodriguez Garzon, Sandro ; Deva, Bersant (2019-11-06)

Today, community initiatives to improve the urban quality of life can be conducted in a more focused way because local authorities and urban planners are able to reveal urban hotspots through the investigation of location-annotated crime and accident data. However, urban areas, which according to well-recorded incident data are characterized by a high level of public safety, but which are gener...

Geocoding user queries

Clemens, Konstantin (2020)

While human users refer to locations using toponyms and addresses, computers rely on latitude and longitude coordinates, or similar, numerical encoding of location information. Geocoding is the process of resolving such toponyms and addresses into machine-friendly numerical encoding. Thus, wherever human users need to specify a location to a computer, geocoding is involved. The process, thereby...

STEAM: A Platform for Scalable Spatiotemporal Analytics

Deva, Bersant ; Raschke, Philip ; Rodriguez Garzon, Sandro ; Küpper, Axel (2017)

Spatiotemporal datasets have become increasingly available with the introduction of a various set of applications and services trac- ing the behavior of moving objects. Recently, there has been a high demand in understanding these datasets using spatiotemporal analytics. While being considered of high value, spatiotemporal analytics did not yet see a wide spreading into the actual business work...

Geofences on the Blockchain: Enabling Decentralized Location-based Services

Victor, Friedhelm ; Zickau, Sebastian (2018)

A decentralized ride- or carsharing application is among the early proposals of what smart contracts on blockchains may enable in the future. To facilitate use cases in the field of location-based services (LBS), smart contracts need to receive trustworthy positioning information, and be able to process them. We propose an approach on how geofences can be defined in smart contracts, and how sup...

Managing cloud ecosystems

Slawik, Mathias (2018)

In recent years, the ever-growing proliferation of cloud services led to the creation of large cloud ecosystems. The most prominent example is the cloud ecosystem of Amazon Web Services (AWS), which now has over 8,000 partners and more than $ 18 billion in revenue in 2017. In addition to these "giants", many smaller ecosystems address more specific challenges. An example is the TRESOR cloud eco...

Blockchain-based Supply Chain Traceability: Token Recipes model Manufacturing Processes

Westerkamp, Martin ; Victor, Friedhelm ; Küpper, Axel (2018)

Growing consumer awareness as well as manufacturers’ internal quality requirements lead to novel demands on supply chain traceability. Existing centralized solutions suffer from isolated data storage and lacking trust when multiple parties are involved. Decentralized blockchain-based approaches attempt to overcome these shortcomings by creating digital representations of physical goods to facil...

Seamless interoperability and data portability in the social web for facilitating an open and heterogeneous online social network federation

Göndör, Sebastian Jürg (2018)

Online Social Networks (OSN) have become an integral part of our everyday lives. We express ourselves, create and collect content such as images or videos, share content and information with our friends and colleagues, exchange messages, or keep track of what's happening in the world. Yet, despite social communication being implicitly a distributed, decentralized phenomenon, most OSN services a...
