1  Abstract—This paper will discuss the challenges in tooling around the management and utilization of knowledge space structures, via standardized APIs for external Adaptive Learning Systems (ALS) to consume. It then describes how these challenges are addressed in a graph based knowledge management framework application designed for external ALSs.

Application Programming Interfaces (APIs) often define object protocols. Objects with protocols have a finite number of states and in each state a different set of method calls is valid. Many researchers have developed protocol verification tools because protocols are notoriously difficult to follow correctly. However, recent research suggests that a major challenge for API protocol programmers...

The article deals with the problem of texture description. It presents a statistical approach. Specifically it introduces the use of firstand second-order statistics on texture color spaces. At the end we also give estimations of computational time complexities of calculations of parameters presented in this article and describe our experience on one application domain. This study is a prelimin...

In tuple space approaches to context-aware mobile systems, the notion of context is defined by the presence or absence of certain tuples in the tuple space. Existing approaches define such presence either by collocation of devices holding the tuples or by replication of tuples across all devices. We show that both approaches can lead to an erroneous perception of context. Collocation ties the p...

Talplanner is a forward-chaining planner which utilizes domain-dependent knowledge to control search in the state space generated by action invocation. The domain-dependent control knowledge, background knowledge, plans and goals are all represented using formulas in a temporal logic called TAL. TAL has been developed independently as a formalism for specifying agent narratives and reasoning ab...

Interest in synthesis of Application Specific Instruction Processors or ASIPs has increased considerably and a number of methodologies have been proposed in the last decade. This paper attempts to survey the state of the art in this area and identifies some issues which need to be addressed. We have identified the five key steps in ASIP design as application analysis, architectural design space...

. Modern digital encyclopedias contain hundreds of thousands of textual articles and multimedia elements. Alternative discovery techniques facilitating the visual exploration of encyclopedia knowledge spaces have recently received much attention. We present the results of a comparative usability evaluation of a two-dimensional and a three-dimensional visualization system integrated with the Bro...
