Title:

A Multi-Data Mining Approach for Shelf Space Optimization - Considering Customer Behaviour

Authors:

Sheng-Hsiang Huang, Chieh-yuan Tsai and Chih-Chung Lo

Abstract: A well product-to-shelf assignment strategy can help customers easily find product items and dramatically increase the retailing store profit. Previous studies in this area usually applied the space elasticity to optimize product assortment and space allocation models. However, a well product-to-shelf assignment strategy should not only consider product assortment and space elasticity. Thus, this study develops a product-to-shelf assignment approach by considering both product association rules and traveling behaviour of consumer. Specifically, the first task of this research is to develop a method to discover traveling behaviour of consumer, which includes both product association rules and traveling behaviour of consumer, in the store. The second task is to construct and solve a product-to-shelf assignment model, based on the information provided in the first task. In this research, products are classified as major item, minor item and the others. Only minor will be reassigned. Experimental result shows our proposed method can reassign minor items to suitable shelves and increase cross-selling opportunity of major and minor items.

Business Models for Cloud-based High Perfomance Computing Service Provision - Insights from the Swiss Higher Education Sector

Authors:

Markus Eurich and Roman Boutellier

Abstract: In 2013, the Swiss Federal Institute of Technology in Zurich (ETH Zurich) and the University of Zurich jointly set up a Cloud stack in order to experiment with high performance computing (HPC) service provision in higher education institutions and its corresponding business model alternatives. This project demonstrated that Cloud-based service provisioning is possible for HPC and can be applied to big data problems as well. On this basis and against the background of new public management reforms, this study aims to foster the understanding of the business model aspects: value proposition and revenue mechanisms. Therefore, 14 interviews were conducted on the potential use of Cloud HPC services and revenue mechanisms. The results show that HPC service providers appreciate Cloud computing providing shorter time to service and more customized services; and eventually becoming more transparent and efficient, i.e. complying with new public management concepts. However, the service consumers do not see a real need to consume Cloud-based services as there is hardly any "Cloud-only" application at the moment. Finally, the three revenue mechanisms ‘pay per use’, subscription, and ‘pay for a share’ are discussed.

Decision Support and Online Advertising - Development and Empirical Testing of a Data Landscape

Authors:

Thomas Hansmann and Florian Nottorf

Abstract: The number of data sources available inside and outside companies and total data points increase, which makes the coordinated data selection in the forefront of decision making with respect to a specific economic goal becomes more and more relevant. To assess the available data and enhance decision support, we develop a framework including a process model that supports the identification of goal-oriented research questions and a data landscape that provides a structured overview of the available data inside and outside the company. We empirically tested the framework in the field of online advertising to enhance decision support in managing display advertising campaigns. The test reveals that the developed data landscape supports the identification and selection of decision-relevant data and that the subsequent analysis leads to economic valuable results.

A Resource-aware Simulation Tool for Business Processes

Authors:

Vincenzo Cartelli, Giuseppe Di Modica and Orazio Tomarchio

Abstract: The deep knowledge of internal and external business processes, along with the capability of governing them, are a key requirement for enterprises to survive. In the dynamic and unpredictable worldwide market, the achievement of business goals depends on the ability of enterprises to adapt to new market conditions by promptly re-engineering their processes. The cost for process re-engineering may be not negligible, if we consider that it may require several refinement steps and that tuning processes on-the-job may impair regular business activities. To this end, there is a growing interest towards tools that allow to simulate process modifications before actually enforcing such changes. In this paper we propose a tool for business process simulation which makes use of modeling specifications such as the Business Process Model and Notation (BPMN) and exploits the rigor of the Colored Petri Nets (CPNets) formalism. With respect to other approaches proposed in the literature, the one presented here defines a detailed model of enterprise’s resources (both human and non-human) and cost allocation inspired to the Activity Based Costing (ABC) accounting principles. A case study test was conducted on a prototype implementation and related results are presented.

Title:

The Use of Social Media to Enrich Information Systems Field Trip Experiences

Authors:

Laddawan Kaewkitipong, Charlie Chen and Peter Ractham

Abstract: A well-designed field trip can promote active learning and reinforce classroom materials (Kisiel, 2006). Few studies examine the potential of using social media to enhance IS field trip experiences by promoting active and collaborative learning. One major barrier to the exploitation of this potential is the adoption of social media by students as a learning tool to enhance field trip experiences. Therefore, the first and foremost task is to understand the motivation and satisfaction of students with the use of social media to enhance IS field trip. The research set to understand factors that could help increase students’ satisfaction with the use of social media to enhance IS fieldtrip and an intention to continue to do so in future field trips. The research shows that to help increase user satisfaction with the use of social media to enhance field trip study and an intention to do so, course instructors should ensure that students perceive the use of social media for enhancing field trip study as effortless, useful, and well used and accepted by their peers. Future research may further study how we should incorporate the use of social media to better enhance the field trip learning performance.

Open Source Geographic Information System and Petrel Software - Adaptation and Integration

Authors:

B. Sadoun, O. Al-Bayari and Samih Al Rawashdeh

Abstract: We present here the development of an Open Source Geographic Information System (OSGIS) tool using MapWindow GIS and petrel software to prove its efficiency for different applications. Geographic Information System (GIS) is a computer system capable of capturing, storing, analyzing, and displaying geographically all types of data. MapWindow is free of charge, extensible geographic information system (GIS) that can be used as an open-source alternative to desktop GIS to develop and distribute custom spatial data analysis tools. It is a "Programmable Geographic Information System" that supports manipulation, analysis, and viewing of geospatial data and associated attribute data in several standard GIS data formats. It is a mapping tool, a GIS modeling system, and a GIS application programming interface (API) all in one convenient redistributable package. It was developed by MapWindow Open Source Team to address the need for a GIS programming tool that could be used in engineering research, without requiring the purchase of a commercial GIS system, or become a GIS expert. In the following, we use Petrel software for subsurface interpretation and modeling to build and update reliable subsurface models for a study area. It allows the user to interpret seismic data, perform well correlation, build reservoir models suitable for simulation, submit and visualize simulation results, calculate volumes, produce maps and design development strategies to maximize reservoir exploitation. A new kind of application is tested for the sake of scientific satisfaction. We had used MapWindow in many applications and always proved efficient. We found Open Source MapWindow GIS is as efficient as the commercial GIS for essential applications such as Mapping, Navigation, and Tracking. Moreover, it is a free of charge tool. We have been using it in our applications and research such as OSGIS for BAU and in the design of a web site for navigation and tracking to be used by interested users on the web.

Authors:

George Kakarontzas, Leonidas Anthopoulos, Despoina Chatzakou and Athena Vakali

Abstract: Enterprise architecture for smart cities is the focus of the research project “EADIC - (Developing an Enterprise Architecture for Digital Cities)” which is the context of the reported results in this work. We report in detail the results of a survey we contacted. Using these results we identify important quality and functional requirements for smart cities. Important quality properties include interoperability, usability, security, availability, recoverability and maintainability. We also observe business-related issues such as an apparent uncertainty on who is selling services, the lack of business plan in most cases and uncertainty in commercialization of services. At the software architecture domain we present a conceptual architectural framework based on architectural patterns which address the identified quality requirements. The conceptual framework can be used as a starting point for actual smart cities’ projects.

Do Specific Text Features Influence Click Probabilities in Paid Search Advertising?

Authors:

Tobias Blask

Abstract: Paid Search Advertisers have only very few options to influence the user’s decision to click on one of their ads. The textual content of the creatives seems to be one important influencing factor beneath its position on the Search Engine Results Page (SERP) and the perceived relevance of the given ad to the present search query. In this study we perform a non reactive multivariate test that enables us to evaluate the influence of specific textual signals in Paid Search creatives. A Bayesian Analysis of Variance (BANOVA) is applied to evaluate the influence of various text features on click probabilities. We conclude by finally showing that differences in the formulation of the textual content can have influence on the click probability of Paid Search ads.

Business Model Framework to Provide Heterogeneous Mobility Services on Virtual Markets

Authors:

Markus C. Beutel, Christian Samsel, Matthias Mensing and Karl-Heinz Krempels

Abstract: Growing spontaneous mobility and decreasing affinity to automobile ownership in younger generations demand for an integrated service for intermodal mobility. In areas with lacking coverage of traditional public transportation, extending the coverage by integrating alternative services like car sharing, seems promising. Because of the very different nature, the collaboration between traditional public transport and emerging mobility services requires fundamental changes to business models. Current business models are designed under the assumption of separation and competition, which contradicts the idea of collaboration. Therefore, a restructuring of all main pillars of business models under the consideration of mutual interdependencies is required. This work defines such business model pillars and contributes a business model framework for providing different mobility services on centralized virtual markets. Basis is a joint platform which enables collaboration between multiple services to provide a collective intermodal mobility service to the customer.

Simulating Digital Businesses using an Agent Based Modeling Approach

Authors:

Aneesh Zutshi, Antonio Grilo and Ricardo Jardim-Gonçalves

Abstract: This paper proposes a complex systems approach to understand the growth and decline of Digital Businesses. Digital Businesses are characterised by unique factors such as a highly networked online customer base, where word of mouth spreads very fast, and minimal cost of incremental users due to economies of scale. Thus online businesses peak and plummet rapidly making it difficult to fathom their success. Through an Agent Based Modeling approach we propose that online businesses can be represented as simulation models which can enable forecasting, what-if analysis and optimization of business parameters.

Authors:

Ana Hol, Omar Mubin and Athula Ginige

Abstract: Literature indicates that SME (Small to Medium) farmers in peri-urban Sydney, Australia region are faced with uncertainties when selling their produce. Majority of farmers sell produce via agents, some sell produce via markets however in either case farmers do not get the full overview or the transparency of the expected market demands and prices. To identify if a suitable business model could be proposed, a carefully selected group of five peri-urban farmers has been studied in detail. Results indicate that through collaboration and networking farmers would be able to get a comprehensive overview of the markets and the digital-eco-system. In addition it is expected that this would further allow farmers to sell their produce via both traditional sale mediums as well as new more enhance mediums of the digital era.

Authors:

Shohei Suzuki and Shoichi Morimoto

Abstract: The tourism industry has been becoming the main business in Japan. In tourism industry, public relations from tourist areas is important to attract tourists, however, it has not been sufficiently performed in Japanese tourism industry. It is also common knowledge that tourism information systems with ICT (Information and Communication Technologies) are effective for such the activities. Therefore, we have proposed a tourism marketing technique utilizing ICT based on the concepts of service marketing. In the service marketing field, it is said that internal marketing to employees will be possible to provide high-quality services. Thus our tourism marketing technique electronically approaches local residents and local firms, which are the employees in the case of tourism.

e-Shop User Preferences via User Behavior

Authors:

Peter Ojtáš and Ladislav Peška

Abstract: We deal with the problem of using user behavior for business relevant analytic task processing. We describe our acquaintance with preference learning from behavior data from an e-shop. Based on our experience and problems we propose a model for collecting (java script tracking) and processing user behavior data. We present several results of offline experiments on real production data. We show that mere data on users (implicit) behavior are sufficient for improvement of prediction of user preference. As a future work we present richer data on time dependent user behavior.

Usage of Semantic Transformations in B2B Integration Solutions

Authors:

Leonid Shumsky, Pavel Shapkin and Viacheslav Wolfengagen

Abstract: We propose a computation-oriented approach to ontology-based B2B integration. The domain ontology is used within the integration platform as a scheme for internal data representation. The main idea is to represent the ontology in a form that enhances the usage of static and dynamic type-checking features offered by the programming language compiler or runtime environment. For these purposes the ontology is represented as a set of types and transformation functions. We study the resulting integration platform architecture and compare expressive power and logical inference possibilities to other ontology representations.

Automatic Business Process Model Assembly on the Basis of Subject-Oriented Semantic Process Mark-up

Authors:

Alexander Gromoff, Nikolay Kazantsev, Pavel Shapkin and Leonid Shumsky

Abstract: Business processes of large companies often lack the flexibility of their smaller competitors. This fact results in slower reaction to the changes in business environment which usually require to launch complicated IT projects. Nevertheless many tasks faced in these situations by IT departments have standard solutions which could be expressed in form of semi-formalized best practices and recommendations. Authors propose a business process model enriched by the semantic mark-up that enables to represent these recommendations in form of fully formalized high-level process descriptions. Using the proposed technical approaches concrete business process models can be generated from these descriptions. Authors discuss formal methods of searching the relevant high-level descriptions as well as rating and evaluation of the generated concrete models based on different criteria.

A Research on Inflation Expectations Measurements and Applications - A View Based on Network Behavior

Authors:

Yi Sun, Benfu Lv and Tian Xue

Abstract: In this paper, a thinking and research method of inflation expectations measurements based on web search data is proposed. First, a conceptual framework between search data and inflation expectations is built in order to clarify their mechanism of association. Then, a index of web inflation expectations is built by using principal component analysis and its effectiveness is verified. The results show that the index of inflation expectations based on web search behaviour is highly correlated with inflation trends, and a stable long-term co integration relationship exists between them, and the actual inflation is the Granger cause of inflation expectations. The conclusions by applying the method presented in this paper are agreed to the mainstream research in academe, which proves the rationality and feasibility of the research ideas and offers new sources of data to monitor the macroeconomic situation.

Location Data – A Trade-off between Control and Value - Business Model Implications

Authors:

Jonas Breuer, Heritiana Ranaivoson, Uschi Buchinger and Pieter Ballon

Abstract: The evolution of mobile technologies, and the enormous increase of users have also consolidated location related services as an inherent part of the mobile service landscape. The possibilities to detect one's whereabouts and relate them to any kind of networked information offer benefits for users and various kinds of businesses. However, LBS also present issues, harmful particularly to users’ privacy. This paper assesses mutually beneficial interaction in multi-sided markets (value is collective and actors are interdependent) and the gatekeeper role of user ownership (i.e. control over the user and data). It adopts a business modelling perspective to: a) define the value network around LBS as two-sided markets, where the LBS provider intermediates between end-users and Third Parties; and b) extract potential revenue models. It focuses on trade-offs between who has control in the ecosystem and how value is created. Finally, the paper assesses how current developments around LBS contribute to changes in the position of the user within the ecosystem.

Towards Real-time Collaboration in User Interface Mashups

Authors:

Alexey Tschudnowsky, Michael Hertel, Fabian Wiedemann and Martin Gaedke

Abstract: Recently, user interface mashups have become a popular approach for covering the long tail of end-user needs. The simple composition paradigm and rich tool support aim at enabling even non-programmers to aggregate data and application logic to solve situational business tasks. Despite of existing assistance mechanisms, both development and usage of UI mashups remain mostly a \emph{single-user} activity. As a result, novices are usually left alone in case of configuration problems or unexpected errors. Furthermore, the work cannot be distributed efficiently to solve tasks faster. This paper presents an approach to make development of and interaction with mashups a collaborative process. We show, how one can extend today's composition platforms towards real-time collaboration and demonstrate the approach in the context of the open-source mashup platform Apache Rave.

Authors:

Jedrzej Musial, Johnatan E. Pecero, Mario C. Lopez, Hector J. Fraire, Pascal Bouvry and Jacek Blazewicz

Abstract: In this paper we deal with the Internet Shopping Optimization Problem. An extended model that includes price sensitive discounts is considered. A set of algorithms to solve the Internet Shopping Optimization Problem with Price Sensitivity Discounts (ISOPwD) is introduced. The algorithms are designed to consider a different solution quality regarding computational time and results close to the optimum solution. Simulations based on real world data assess the new set of heuristics. The results of the proposed algorithms were compared with the optimal solutions, computed by a branch and bound algorithm. The scalability is evaluated by increasing the problem sizes. Computational experiments are performed and their results are carefully analyzed and discussed. The paper should be perceived as a work in progress - position paper.

Authors:

Britta Fuchs and Thomas Ritz

Abstract: The relevance of usability with regard to Blended Shopping concepts is addressed in this paper. First an introduction into usability as a crucial acceptance factor for applications is given. Then Blended Shopping - the combination of traditional retail and eCommerce – in practice is analyzed. Research findings presented reveal that merchants do not apply Blended Shopping concepts in practice until now. It is assumed that usability flaws are one of the main barriers for Blended Shopping. Different dimensions of usability problems that prohibit a wide acceptance among users are explained and analyzed. Then a methodological approach is suggested to address vertical problems. A technology-driven approach to address horizontal problems is described. The paper will close with a future outlook.

Semantic and Syntactic Matching of e-Catalogues - Using Vector Space Model

Authors:

Ahmad Mehrbod, Aneesh Zutshi and António Grilo

Abstract: E-catalogues play a key role in e-procurement. Matching a product request from a buyer with products e-catalogues, helps companies to find business partners in e-marketplaces. Plethora of e-catalogue standards and enterprise specific formats is one of the major challenges in the matching process. In addition to this syntactic heterogeneity, the same product concept can be expressed using different words that causes semantic diversity in e-catalogues. In this paper, we propose a flexible approach to e-catalogue matching using Vector Space Model. Each e-catalogue is interpreted syntactically in its schema and semantically in an ontology that is developed based on its product classification system. Schemas and ontologies are added to the VSM by adding the syntax of the structure and semantic of the ontology to the indexing and searching mechanisms. The matching process uses the syntactic and semantic metadata for interpreting each e-catalogue as much as the information is available for the system, but is not dependent on this information.

Authors:

Jakub Marszałkowski, Łukasz Rusiecki, Maciej Drozdowski and Hubert Narożny

Abstract: Tag clouds provide a graphical method of summarizing content of a text document (e.g. of a web page) with a set of phrases projected onto a plane. In this paper we consider building aesthetic tag clouds algorithmically for website use. General design choices in tag-cloud construction are analyzed. State of the art will be outlined along the lines of these design choices. Special requirements imposed on tag clouds used on web sites are presented. Rules of beautiful page setting existing in typography are discussed and subsequently applied in an attempt to quantify aesthetic aspect of tag cloud appearance. The quantification is performed with the goal of constructing an objective function to be optimized in tag cloud construction. Then, a mathematical formulation for tag clouds construction is given. Finally, algorithms constructing tag clouds by optimization are given.

QoS based Resource Allocation and Service Selection in the Cloud

Authors:

Rima Grati, Khouloud Boukadi and Hanêne Ben-Abdallah

Abstract: Web service composition builds a new value-added web service using existing web services. A web service may have many implementations, all of which have the same functionality, but may have different Quality of Service (QoS) values. Hence, a challenging issue of web service composition is how to meet QoS and to fulfil cloud customers’ expectations and preferences in the inherently dynamic environment of the Cloud. Addressing the QoS based web service selection and resource allocation is the focus of this paper. This challenge is a multi-objective optimization problem. To tackle this complex problem, we propose a new Penalty Genetic Algorithm (PGA) to help a Cloud provider quickly determine a set of services that compose the workflow of the composite web service. The proposed approach aims to, at the one hand, meet QoS constraints prioritized by the Cloud customer and, at the other hand, respect the resource constraints of the Cloud provider. To the best of our knowledge, this is the first attempt to handle the problem of the optimal selection of web services while taking into account the resource allocation in order to guarantee the QoS imposed by the Cloud customer and to maximize the profit of the Cloud provider. The experimental results of Penalty Genetic Algorithm show that it outperforms the Integer Programming method when the number of web services and the number of resources are large.
