Colloquium IS (November 2, 2018) – Design of a reference model-based approach to support business-IT alignment improvement in co-creation value networks

Posted on by

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday, November 2, 2018, 16:00 – 17:00 (Paviljoen K.16).

Speaker: Samaneh Bagheri

Title: Design of a reference model-based approach to support business-IT alignment improvement in co-creation value networks

Abstract:

Over the past three decades, business-IT alignment (BITA) has resided among the top ten concerns of organizations worldwide. One of the primary challenges which confront organizations is that BITA is a moving target due to changes in the organization’s external and internal environments. Hence, BITA as a moving target should be improved continuously over time. However, achieving better BITA is difficult, and organizations encounter several problems such as communication flaws and a lack of shared domain knowledge among others.

Addressing BITA might even more challenging in a co-creation value network setting where heterogeneous actors collaborate to realize shared values through design and delivery of customized solution-oriented services. In such a setting, IT provides technical foundations for collaboration and information exchange among actors. This implies that BITA has to be addressed at a network level.

In this presentation, I will introduce a reference model-based approach to support BITA improvement process in a co-creation value network setting. I will explain the research process that has been followed to design this approach.

From now on, I will work here as an exchange PhD of the Brain Bridge Project for another two years.
It is the first time that I have been to The Netherlands. Although the beginning is always difficult, I will try to integrate our group as soon as possible. I really like the life and the people here. And I believe there will be some surprise waiting for me in the future!

 

Colloquium IS (October 5, 2018) – Advanced dynamic resource allocation in BPM systems

Posted on by

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday, October 5, 2018, 16:00 – 17:00 (Paviljoen K.16).

Speaker: Irene Vanderfeesten

Title: Advanced dynamic resource allocation in BPM systems

Abstract:

In this presentation I will outline my work in the area of Human Aspects of Business Information Systems Engineering (the focal area of my Associate Professor position), with special attention for the topic of advanced dynamic resource allocation. Business Process Management Systems (BPMSs) automatically execute business processes and coordinate work amongst resources. Humans execute tasks in these processes and interact with the BPMS through a task list. In most systems the mechanism to select and allocate the right resource to execute a task is fairly basic and only takes into account organizational information of a resource such as the position, department, business unit, etc. In this presentation I discuss more advanced ways of allocating resources using detailed information of the resources (such as experience, capabilities, preference, etc.) and cases. With some examples from the administrative domain I illustrate how process performance is improved through this. Currently, in the HORSE project, these mechanism are also extended for the manufacturing domain in which human and robotic resources collaborate on tasks or can be interchangeably allocated to execute a task. I will give you a flavor of these new developments and an outlook into the next steps.

Hi, I am Kalliopi Zervanou and I am a computational linguist. In an almost previous life, I got my Bachelor in French Literature & Linguistics from Aristoteles University of Thessaloniki and sometime after working as a conference interpreter I returned to academia for an MSc in Machine Translation from the UMIST Language Engineering Dept., and a PhD in Information Extraction from the School of Computer Science of the University of Manchester. My research focuses in information management of mainly unstructured text data (free-text): I have a long experience in information extraction research, including language technology applications in information retrieval, digital libraries and semantic web, for a variety of domains (financial, biomedical, humanities, police). Since 2009, I have been actively involved in digital humanities in a series of projects and as a leading member of the computational linguistics digital humanities community, both as programme chair of the LaTeCH workshop series, as well as founding member of the respective ACL Special Interest Group, SIGHUM, which I also serve as elected secretary for three consecutive terms, since 2013. My most recent research focused on historical data modelling issues and event extraction from texts. 

 

Colloquium IS (September 7, 2018) – Factors that complicate selecting software requirements

Posted on by

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

September 7, 2018, 16:00 – 17:00 (Paviljoen K.16).

Speaker: Hans Schoenmakers

Title: Factors that complicate selecting software requirements

Subtitle: Validating Factors from Literature in an Empirical Study

Abstract:

In market-driven software product development, new features may be added to the software, based on a collection of candidate requirements. Selecting requirements  however is difficult. Despite all work done on this problem, known as the next release problem, what is missing, is a comprehensive overview of the factors that complicate selecting software requirements. The research consists of a systematic literature review, searching for occurrences in the literature where a causal relation was suggested between certain conditions and the difficulty of selecting software requirements. Clustering the 156 findings, found by analyzing 544 papers, led to 33 complicating factors that were classified in eight groups. The complicating factors were validated in semi-structured interviews with twelve experts from three different industrial organizations. In these interviews both questions on experiences with the complicating factors and on why they were complicating were asked. The results aid in getting a better understanding of the complexity of selecting requirements.

 

 

Colloquium IS (July 6, 2018) – Discovering Anomalous Frequent Patterns from Event Logs

Posted on by

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

July 6, 2018, 16:00 – 17:00 (Paviljoen K.16).

Speaker: dr. Laura Genga

Title: Discovering Anomalous Frequent Patterns from Event Logs

Abstract:

Conformance checking allows organizations to compare process executions recorded by the IT system against a process model representing the normative behavior. Most of the existing techniques, however, are only able to pinpoint where individual process executions deviate from the normative behavior, without considering neither possible correlations among occurred deviations nor their frequency. Moreover, possible parallelisms among process activities are usually neglected,

which can lead to inaccurate diagnostics. In this talk, I will introduce an approach to extract anomalous frequent patterns from historical logging data. The extracted patterns can exhibit parallel behaviors and correlate recurrent deviations that have occurred in possibly different portions of the process, thus providing the analysts with a valuable aid in investigating nonconforming behaviors. The approach has been evaluated using both synthetic and real-life logs.

 

Colloquium IS (June 1, 2018) – EHR-data driven clinical risk prediction for CVD

Posted on by

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

June 1, 2018, 16:00 – 17:00 (Paviljoen K.16).

Speaker: Zhengxing Huang from Zhejiang University

Title: EHR-data driven clinical risk prediction for CVD

Abstract:

With the rapid development of hospital information systems, a large volume of electronic health records (EHRs) has been produced, which provides a comprehensive source for clinical risk prediction. In this talk, I am concerned with the problem of utilizing the heterogeneous EHR data to assist clinical risk prediction for cardiovascular disease patients.  Specifically, two challenges are addressed in this study: 1) how to annotate unstructured EHR data for generating a benchmark dataset, and 2) how to train a predictive model on the benchmark patient samples which are typically imbalanced and correlated to each other.

Colloquium IS (May 4, 2018) – Managing variability in knowledge-intensive processes

Posted on by

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

May 4, 2018, 16:00 – 17:00 (Paviljoen K.16).

Speaker: Rik Eshuis

Title: Managing variability in knowledge-intensive processes

Abstract:

In modern organizations, the importance of knowledge workers and the knowledge-intensive processes (KiPs) they perform is ever increasing. Examples of KiPs are new product development processes, smart maintenance processes, diagnosing and treating patients etc. In a KiP a case is processed and evaluated based on human judgement of knowledge workers, who often rely on digitized information to apply their knowledge. Flexible BPM technologies like case management and business artifacts support KiPs. A KiP model typically needs to be adapted to the case being processed, leading to different but related variant models of a KiP. In this talk, I outline an approach based on business artifacts to manage variability in KiPs, in order to avoid rework and improve the quality of KiPs.
