ARTH 440-010 ART & WARFARE IN LATIN AMERICA Battle scenes, revolts, arms, soldiers and heroes as shaped in the arts of Latin America from pre-Hispanic to modern times. ARTH 605-010 EGYPTOMANIA Explores ways that Western cultures have constructed the idea of and appropriated Egypt from antiquity to the present day. Source materials include writings, picture books, architecture, fine art, decorat...

In large document bases, hypertext retrieval techniques can be favourably used. However, for those bases, manual creation of links is not feasible. In this paper, we present a system that manages the automatic conversion of texts into hypertexts based on link type descriptions: it is discussed, where a standard database management system can be used for this goal directly and where additional o...

Providing an adequate route description requires in-depth spatial knowledge of the route in question. In this article we demonstrate that despite having travelled a route recently and having much experience of the area in question, an individual may lack such a degree of knowledge. Previous research and experience informs us that a map is an effective tool for bridging gaps in one’s spatial kno...

This paper deals with the generation of deenite (i.e., uniquely referring) descriptions containing semantically vague expressions (`large', `small', etc.). Firstly, the paper proposes a semantic analysis of vague descriptions that does justice to the context-dependent meaning of the vague expressions in them. Secondly, the paper shows how this semantic analysis can be implemented using a modiic...

Incorporating new information into a knowledge base is an important problem which has been widely investigated. In this paper, we study this problem in a formal framework for reasoning about actions and change. In this framework, action domains are described in an action language whose semantics is based on the notion of causality. Unlike the formalisms considered in the related work, this lang...

We describe a new representation for learning concepts that di ers from the traditional decision tree and rule approach. This representation, called prototypical concept descriptions, can represent several prototypes for a concept. We also describe PL, our algorithm for learning these prototypes, and demonstrate that prototypical concept descriptions can, in some situations, classify more accur...

Projects will be carried out in groups of 3 or 4. The final deliverables will be a report and a presentation. The report should be 6-10 pages, consisting of the problem statement, your approach, and your results. The presentation is a summary of the report, and will be given to the rest of the class. Here is a timeline: • By 9/21, register your preferences for the various projects listed below ...

Most symbolic learning methods are concerned with learning concept descriptions in the form of a decision tree or a set of rules expressed in terms of the originally given attributes. For some practical problems, these methods are inadequate because they cannot learn conditions that require counting of some object properties. Such problems occur, for example, in engineering, economy, medicine a...
