Chatbots: Are they Really Useful?

Chatbots are computer programs that interact with users using natural languages. This technology started in the 1960’s; the aim was to see if chatbot systems could fool users that they were real humans. However, chatbot systems are not only built to mimic human conversation, and entertain users. In this paper, we investigate other applications where chatbots could be useful such as education, i...

Flux Caches: What Are They and Are They Useful?

In this paper, we introduce the concept of flux caches envisioned to improve processor performance by dynamically changing the cache organization and implementation. Contrary to the traditional approaches, processors designed with flux caches instead of assuming a hardwired cache organization change their cache ”design” on program demand. Consequently program (data and instruction) dynamic beha...

Two route landmarks are more useful to navigating ant colonies when they are dissimilar

Visual landmarks are important navigational aids to many animals, and when more than one is available their juxtaposition can convey valuable new information to a navigator about progress toward a goal, depending on the landmarks' comparative distinctiveness. We investigated the effect of presenting rock ant colonies (Temnothorax albipennis) with identical horizontal landmarks either side of th...

Users Are Always Right ... Even When They Are Wrong: Making Knowledge Representation Useful and Usable

Users’ problems in developing applications rarely factor easily so as match the solutions provided by the Knowledge Representation community. If KR is to be applied successfully, the gap between users’ “problem space” and the KR “solution space” must be addressed. Two approaches are suggested: “Intermediate representations” at a higher level of abstraction than current KR languages and a set of...
