Über dieses Buch

The conference series BIR (Business Informatics Research) was established 10 years ago in Rostock as an initiative of researchers from Swedish and German universities. The objective was to create a global forum where researchers in business informatics, seniors as well as juniors, could meet, collaborate and - change ideas. Over the years BIR has matured into a series of international conferences, typically organized in the Baltic Sea region, including Norway and Iceland. A steering committee ensures the high quality of the BIR proceedings. We are very proud that this year an international and very well known editor has agreed to publish selected papers of the conference. The interest in the conference in terms of submissions and participation has steadily increased over the years. This year, we received 53 contributions among which 14 submissions were accepted as long papers and 4 as short papers. A few additional contributions were invited for presentation at the conference. The selection was carefully carried out by an International Program C- mittee. The result is a set of interesting and stimulating papers that address important issues such as knowledge management, ontologies, models, work?ow speci?cations, data bases and OLAP. The conference was opened by an invited technical talk by Dr. Klaus BrunnsteinfromTheUniversityofHamburgwhodiscussedthetopic“TheInf- mation Society on the Way to Web 3.0: Perspectives, Opportunities and Risks”, which is challenging for all of us.

Knowledge and Information Management

Using HCI-Patterns for Modeling and Design of Knowledge Sharing Systems

Abstract
In this paper we describe a pattern-based approach for designing highly-usable individualized multi-media inter faces for enterprise knowledge identification, structuring and communi cation. A pattern-based development workflow uses do main analysis and hierarchical pattern language repositories to extract HCI patterns and define solutions for structuring, accessing and communicating the knowledge distributed in the employees´ minds, their desktops and mobile devices as well as databases and other knowledge sources of an enterprise. An attached tool environment is used for modeling the entire application and for generating parts of the UI code.

Information Quality Testing

Abstract
When a new system, such as a knowledge management system or a content management system is put into production, both the software and hardware are systematically and thoroughly tested while the main purpose of the system — the information — often lacks systemic testing. In this paper we study how to extend testing approaches from software and hardware development to information engineering. We define an information quality testing procedure based on test cases, and provide tools to support testing as well as the analysis and visualization of data collected during the testing. Further, we present a feasibility study where we applied information quality testing to assess information in a documentation system. The results show promise and have been well received by the companies that participated in the feasibility study.

Enterprise Models as Interface for Information Searching

Abstract
Enterprise knowledge modelling in general offers methods, tools and approaches for capturing knowledge about processes and products in formalized models in order to support organizational challenges. From the perspective of information systems development, the use of enterprise models traditionally is very strong in the earlier development phases, whereas approaches for applying enterprise models in later development phases exist, but are not as intensely researched and elaborated. We argue that enterprise models should be considered as carrier of enterprise knowledge, which can be used to a larger extent in creating actable solutions for enterprise problems. With competence supply as an example, the focus of the paper is on using enterprise models as interface for information searching. The main contributions of the paper are (1) to show that it is feasible and produces pertinent results to use enterprise models for expressing information demand, (2) architecture and implementation of an IT solution for this purpose and (3) lessons learned from validating this approach.

Model for Project Management for Development and Implementation of E-Learning Courses

Abstract
The aim of this article is to propose an integrated project management model for development and implementation of e-learning courses. The management model is a process solution map containing processes models integrated with project management categories of: risk, quality, control, costs, time, resources, workflow, document flow and communication with proper templates attached. The model is assigned for instructional designers and project managers to accelerate e-learning courses development. The starting point of the article is an analysis of the weaknesses in standard models for development of e-learning courses. For the thesis confirmation a case studies of four e-learning institutions with significant experience in e-learning field is being shown. The last, key part of the article describes the elaborated model. It contains presentation of process map with detailed processes models consisting of activities with integrated project management categories. The article is based on case studies of institutions with significant e-learning projects realization experience, like: Oncampus, Lübeck University of Applied Science; Distance Education Centre, Kaunas University of Technology; Center of Distance Education Development, Higher Banking School and PEUG, University of Gdansk. It also includes author’s six years experience gained by participation in e-learning projects, like Baltic Sea Virtual Campus and national POKL as courses’ author, instructional designer and it coordinator.

Optimization of Automated Trading System’s Interaction with Market Environment

Abstract
This work is focused on the automated trading systems (ATS) design and optimization. In a preparation phase before use, an optimization of interaction of such systems with its intended market environment should be done. The technical analysis indicators are most frequently used in ATS. Optimization is done by testing of different settings of MACD indicator and optimal settings depend heavily on market parameters. The intended use of the ATS is to perform its activity independently to some extend (depending on user’s preferences). The main aim is to enhance automated trading system performance, in order to improve its usefulness and acceptability for the user. Paper will be focused on futures markets only (Chicago and New York), but results are applicable to other areas of trading as well.

E-Learning Application Support for SME

Abstract
E-learning is widely accepted as a method for knowledge transfer, however, this development is more focused on big enterprises than on small and medium enterprises (SME). These enterprises characterized by their limited resources and specific requirements, are in need for methods for knowledge transfer and need special software support to experience the advantages of e-learning. A short overview on the situation in SMEs, the needs of SMEs towards e-learning applications as well as a review of the solution of the TT Knowledge Force will be presented in this paper.

Ontologies

Towards Ontology-Based Methodology for Requirements Formalization

Abstract
Implementation of enterprise information management systems is still a challenging task for any organization. One of the key challenges within implementation projects is analysis of business requirements and determination of required system capabilities. Traditionally this challenge is overcome by gathering a team of experienced specialists but we would like to propose an alternate solution: using the ontology based knowledge management system to determine the necessary functionality and configuration of the enterprise information management system based on the user requirements. In this paper we describe the approach for representation of user requirements for such systems as business processes based on the ideas from The Ontology for Linking Processes and IT infrastructure (OLPIT).

A Hybrid Approach for Relating OWL 2 Ontologies and Relational Databases

Abstract
Relating Semantic Web ontologies with relational databases becomes a topical problem as ontologies provide more and richer capabilities for accessing information that is currently closed in heterogeneous and distributed sources e.g. relational databases. The growing number of tools and methodologies are considering this problem but usually they are looking from the point of view of ontologies or from the point of databases. We propose a hybrid approach where ontology classes and properties are mapped to database schema and instances are stored in database tables while more complex constructs that cannot be adequately represented by database concepts are stored in metadata tables. This allows the lossless, bidirectional transformations between ontologies and databases combining advantages and addressing the needs of both worlds.

UML Style Graphical Notation and Editor for OWL 2

Abstract
OWL is becoming the most widely used knowledge representation language. It has several textual notations but no standard graphical notation apart from verbose ODM UML. We propose an extension to UML class diagrams (heavyweight extension) that allows a compact OWL visualization. The compactness is achieved through the native power of UML class diagrams extended with optional Manchester encoding for class expressions thus largely eliminating the need for explicit anonymous class visualization. To use UML class diagram notation we had to modify its semantics to support Open World Assumption that is central to OWL. We have implemented the proposed compact visualization for OWL 2 in a UML style graphical editor. The editor contains a rich set of graphical layout algorithms for automatic ontology visualization, search facilities, zooming, graphical refactoring and interoperability with Protégé 4.

Models and Workflows

Alternative Representations of Workflow Control-Flow Patterns Using HOPS

Abstract
This paper analyzes the applicability of HOPS on describing the workflow patterns, originally published by van der Aalst. The workflow patterns is a widely accepted collection of recurring fragments used for workflow modeling. These patterns can be used for evaluating the capabilities of workflow systems and models. We adopt this, to investigate the application of HOPS. HOPS is a universal specification formalism that can be used to describe cooperating and interacting systems. For this, we provide HOPS implementations of the workflow patterns. This can be used as a basis for future research and to compare HOPS with other formalisms.

Modeling and Formally Checking Workflow Properties Using UML and OCL

Abstract
In this paper, a new metamodel for workflows is described by using UML. The underlying UML class diagram is formally extended with OCL pre- and postconditions for operations and OCL invariants for system states. The metamodel allows the developer to specify processes, activities in processes and temporal relations between them. Known workflow patterns are formally captured in the metamodel and sophisticated temporal relations between activities can be expressed easily. Development of workflow models is explained as well as process instantiation and process execution on the basis of a tool realizing parts of the UML action semantics. Prototypical process execution and animation allows the designer to discover properties of the designed processes and activities in early phases of the development without the need for building a full implementation.

Pondering on the Key Functionality of Model Driven Development Tools: The Case of Mendix

Abstract
Model Driven Architectures and Model Driven Development (MDD) have been used in information system (IS) development projects for almost a decade. While the methodological support for the MDD process is important, the success of a project taking the model driven approach to development also heavily depends on the tool. The tool simply needs to support a set of key functionalities, such as an appropriate level of model abstraction, the refinement of models and finally the execution of models. In this paper we analyze a new MDD tool, namely Mendix, with respect to a number of functionality areas needed to achieve success in a project and capitalize on the benefits of MDD. Our findings are that Mendix use a well selected set of models and that these models are well integrated and suitable for the construction of small systems. Based on the key functionality areas we also point out the weaknesses of the tool.

Maintenance Scenarios for Distributed Application Infrastructures

Concepts with the Focus on Functional and Data Integrity
Abstract
Whenever complex business scenarios terminate prematurely due to an error or the unavailability of applications, the system administration is forced to react as swiftly as possible. The failure of a single component can rapidly impair the whole application infrastructure and can cause serious damage. Failures must be identified, dependencies considered and processes restarted for functional and data integrity to be regained on the business process level. We presented mechanisms for more transparency and better control so that further incidents after problems are known will be avoided. This time we will concentrate on maintenance scenarios by the use of M3DB. Maintenance scenarios for distributed application infrastructures are more complex and need a stronger and more effective integration of technical and business issues. The more maintainable a system landscape is, the higher its availability, reliability and evolvability.

A Selection-Method for Enterprise Application Integration Solutions

Abstract
With new developments such as cloud computing and SOA, integrating different applications is becoming increasingly important. We observed that many organizations have difficulties in the selection of a suitable application-integration solution. In this paper we present a method for the selection of enterprise application integration solutions. This method supports organizations in choosing solutions that consist of both technological and organizational measures. We used an assembly-based method engineering approach to construct the method. We validated the method using a case study and expert reviews.

OLAP Personalization with User-Describing Profiles

Abstract
In this paper we have highlighted five existing approaches for introducing personalization in OLAP: preference constructors, dynamic personalization, visual OLAP, recommendations with user session analysis and recommendations with user profile analysis and have analyzed research papers within these directions. We have pointed out applicability of personalization to OLAP schema elements in these approaches. The comparative analysis has been made in order to highlight a certain personalization approach. A new method has been proposed, which provides exhaustive description of interaction between user and data warehouse, using the concept of Zachman Framework [1, 2], according to which a set of user-describing profiles (user, preference, temporal, spatial, preferential and recommendational) have been developed. Methods of profile data gathering and processing are described in this paper.

Export of Relational Databases to RDF Databases: A Case Study

Abstract
The vast amount of business information nowadays is stored in relational databases. For the Semantic Web vision to become a reality, we need ways how to exploit this data in form of RDF triples. The universal and commonly accepted solution for this problem still does not exist. In most cases, mapping languages are used for specification of correspondences between OWL ontology and DB schema. At the same time, these languages generally are not well suited for specification of mappings in cases when there is a substantial difference between OWL ontology and DB schema. In this paper, we describe a new model transformation-based method for specification of correspondences between the elements of DB schema and OWL ontology. We also present our experience of using this method in a real world use case and sketch direction of future research.

End User Development for OLAP – A Scenario from Food Industry

Abstract
Database applications allow the analysis of complex and large data sets. Such applications typically offer a lot of analysis functions to reveal all kinds of relations inside the data. Nevertheless end-users quite often face situations where they require viewing certain data or relations that is not easily provided by their existing analysis software. To overcome these situations they need means to create their own user interfaces to data that fit their specific requirements. Our solution is a tool that is easily usable for end users, doesn’t require any programming knowledge, but enables them to quickly build a customized user interface to view the data they are specifically interested in. This paper illustrates the usage of our tool in a typical scenario taken from one of our industrial project partners. We show how our tool allows end users to specify interactive applications like spreadsheets. The developed tool is build on top of an OLAP application and is partially based on the Qt Designer.

Mobile Computing from a Developer’s Perspective: A 10-Year Review, 1999–2008

Abstract
This review has examined research in mobile computing from a developer’s perspective. The review was underpinned by the assumption that mobile computing has accentuated factors compared to stationary computing that ought to be managed to harness the possibilities of mobile computing. Applying a developer’s perspective rendered a certain interest in design-oriented research, i.e. prescriptive research. Articles were categorised in three dimensions; the first dimension was developmental factors accentuated by mobile computing. The second dimension regarded the approach, if it was descriptive or prescriptive. The third dimension regarded the organisational settings, if the user were a member of the mobile workforce or not. The purpose of this study was to identify areas of inquiry in mobile computing from a design-oriented perspective. The findings revealed that research among accentuated factors of mobility is unevenly distributed and that research on the mobile workforce is under-represented. However, design-oriented research has a reasonable representation in the set of publications. The under-representation of research concerning the mobile workforce ought to have relevance for business informatics research. In conjunction with these findings some thoughts on future research areas are presented.
