The volume of information of the most various types stored electronically in a company is increasing to an ever-greater extent. While in the field of operational systems everything is aimed at achieving the quickest possible throughput, in the dispositive field, questions regarding the total overview or detailed views are of interest. OLAP servers are multidimensionally structured. They are the...

The increasing market turbulence and the increasing need for the creation of competitive advantages force businesses to rethink the way they perform their business. This rethinking is often performed unstructured or fragmented, and they fail to consider the business as a whole. Therefor there is a need for making a diagnosis as a basis for redesigning the business. In order to perform this diag...

Interactive systems are often developed without taking security concerns into account. We investigated a combination of both HCI models and access control specifications to overcome this problem. The motivation of a combined approach is to narrow the gap between different modeling perspectives and to provide a coherent mapping of modeling concepts. The general goal is a systematic introduction ...

Animation can add significant value to Discrete-Event Simulation by helping verify, validate, and accredit simulation analyses. This is particularly true in construction where typical decision makers are experts in their domain but are not generally proficient in simulation itself. Existing methods of animating simulated construction processes in 3D have a significant limitation. They require t...

Drawing on writings within the CSCW community and on recent social theory, this paper proposes that the adoption of speech act theory as a foundation for system design carries with it an agenda of discipline and control over organization members' actions. I begin with a brief review of the language/action perspective introduced by Winograd, Flores and their colleagues, focusing in particular on...

Many approaches to personalization involve learning short-term and long-term user models. The user models provide context for queries and other interactions with the information system. In this paper, we discuss how language models can be used to represent context and support context-based techniques such as relevance feedback and query disambiguation.

The language/action perspective (LAP) as orginally introduced by Winograd and Flores has inspired several tools and information system design methodologies. The goal of this article is to make the communication norms underlying various LAP workflow loop models (DEMO, ActionWorkflow) explicit and to contrast them with the auditing norms of internal control. It appears that the communicative acti...

Knowledge modeling perspectives on knowledge acquisition suggest that it is reasonable to analyze knowledge bases as collections of models. This paper focuses on those parts of the knowledge base that model the practical reasoning processes of human experts, and asks what properties those models might be expected to have. It surveys the general notion of a model and its connotations in informat...

Ultra-Reliable Low Latency Communication (URLLC) is one of the distinctive features of the upcoming 5G wireless communication, going down to packet error rates (PER) of 10−9. In this paper we discuss the statistical properties of the wireless channel models that are relevant for characterization of the lower tail of the Cumulative Distribution Function (CDF). We show that, for a wide range of c...

Commercial software component models are frequently based on object-oriented concepts and terminology with appropriate binding, persistence and distribution support. In this paper, we argue that a process-oriented view on cooperating software components based on the concepts and terminology of a language/action perspective on cooperative work provides a more suitable foundation for the analysis...
