In this paper we propose a pattern language for learners who want to learn better without killing their creativity. In order to tell a ‘knack’ about the way of learning we apply the method of pattern language, which was originally proposed in architectural design and became famous in software design. Our proposed pattern language for creative learners, which we name “Learning Patterns”, consist...

June 2003 and the eighth European Pattern Languages of Programming conference may yet prove to be the most historic. On the Friday there emerged the first activity of an extremely ambitious experiment which, it is hoped, will run over twelve months and more. If the experiment is successful it may reshape the thinking of the Patterns Movement. The aim of the experiment is to validate the feasibi...

The Class Responsibility Collaborator (CRC) cards are index cards that are utilized for mapping candidates classes in predefined design scenarios; e.g. Use Case Scenarios. The objective of CRC cards is to facilitate the design process while insuring an active participation of involved designers. This paper represents the first attempt towards a CRC card pattern language representation via stabl...

Measurement is an important activity in several domains. Although there are specific concepts regarding measurement in each domain, some concepts are common to all of them. This paper presents a Measurement Ontology Pattern Language (M-OPL) that addresses the measurement core conceptualization. M-OPL can be used for building measurement ontologies to several domains. The ontology patterns that ...

The process of creating the architecture of a software system results in a documentation, which is recognized as a key artifact for stakeholder communication, early analysis of the system, support for quality attributes and trouble-free maintenance. The problem of software architecture documentation remains to a large extent unsolved; however the past few years, significant advances have been m...

Drawing on well-known examples of serendipity in scientific discovery, we develop a set of criteria that can be applied to model and evaluate serendipity in computational settings. We use design patterns, and the growth of a pattern language, as a way to describe the processes of discovery and invention that comprise serendipitous encounters. We show how several earlier patterns of serendipity ...

Developing a pattern language is a non-trivial problem. A critical requirement is a method to support pattern writers with abstraction, so as they can produce generalised patterns. In this paper, we address this issue by developing a structured process of generalisation. It is important that this process is initiated through engaging participants in identifying initial patterns, i.e. directly d...

Since the mid-1990’s the psychological and sociological concept of trust has received increasing attention in the field of electronic commerce by many scholars and was recognized as one of the main reasons why a high number of consumers are still reluctant from buying on the Internet. During about the same period of time the idea of design patterns and pattern languages, originally developed in...

Pattern languages are generalisations of the copy language, which is a standard textbook example of a context-sensitive and noncontext-free language. In this work, we investigate a counter-intuitive phenomenon: with respect to alphabets of size 2 and 3, pattern languages can be regular or context-free in an unexpected way. For this regularity and context-freeness of pattern languages, we give s...

In this paper, we introduce a novel data model for representing symbolic trajectories along with a pattern language enabling both the matching and the rewriting of trajectories. We illustrate in particular the trajectory data type and two operations for querying symbolic trajectories inside the database system Secondo. As an important application of our theory, the classification and depiction ...
