Spatio-temporal data and knowledge have become increasingly important in the last years. In this paper, which introduces the session on Knowledge Engineering Techniques for Spatio-temporal Applications, we outline some issues in geo-spatial research and applications for which the use of innovative knowledge, tools and methodologies is crucial.

Increasingly diverse and useful information repositories are being made available over the World Wide Web (Web). However, information retrieved from the Web is often of limited use for problem solving because it lacks task-relevance, structure and context. This research draws on software agency as a medium through which modeldriven knowledge engineering techniques can be applied to the Web. The...

The support of the software engineering life cycle from the initial negotiation of requirements, through analysis, design, coding, testing, integration, trial, use, enhancement, maintenance and replacement, involves the management of diverse knowledge sources and their dependencies. Requirements negotiation, in particular, involves the management of a heterogeneous collection of materials in su...

Recent efforts in engineering education focus on introducing engineering into secondary math and science courses to improve science, technology, engineering, and math (STEM) education (NAS, 2010). Infusing engineering into secondary classrooms can increase awareness of and interest in STEM careers, help students see the relevance of science and math in their everyday lives, and increase STEM li...

Despite a big progress in solving planning problems, more complex problems still remain hard and challenging for existing planners. One of the most promising research directions is exploiting knowledge engineering techniques such as (re)formulating the planning problem to be easier to solve for existing planners. In particular, it is possible to automatically gather knowledge from toy planning ...

Essentially all current software engineering tools share a common technological approach: They use a shallow representation of software objects and manipulate this representation using procedural methods. This approach has the benefit that it allows one to get off to a fast start and quickly provide a tool that delivers benefits. In addition, software engineering tools can undoubtedly be extend...

We argue below that knowledge engineers (KEs) use a range of techniques ( ). Yet more techniques are constantly being evolved. How sure are we that any of the current KE techniques either work at all or work better than past practice? Currently, our basic question has no clear answer. It is not easy to evaluate software development techniques, be they from software engineering or knowledge engi...

In process engineering, as in many other application domains, the domain specific knowledge is far too complex to be described entirely using description logics. Hence this knowledge is often stored using an object-oriented system, which, because of its high expressiveness, provides only weak inference services. In particular, the process engineers at RWTH Aachen have developed a frame-like lan...
