Compiled knowledge, which allows macro inference steps through an explanation space, can enable explanation-based learning (EBL) systems to reason efficiently in complex domains. Without this knowledge, the explanation of goal concepts is not generally feasible; moreover, the problem of finding the most general operational concept definition is intractable. Unfortunately, the use of compiled kn...

This paper describes a new system called \Maximum Entropy Named Entity" or \MENE" (pronounced \meanie") which was NYU's entrant in the MUC-7 named entity evaluation. By working within the framework of maximum entropy theory and utilizing a exible object-based architecture, the system is able to make use of an extraordinarily diverse range of knowledge sources in making its tagging decisions. Th...

Laurillard (1993: 1) in the book ‘Rethinking University Teaching’ states that “University teachers must take the main responsibility for what and how their students learn”. At the undergraduate level, where the curriculum is fixed and where the students are expected to explore an already known field of knowledge, even the most democratic model of education is more didactic than negotiated. This...

Behavioral models are at the core of FaultDetection and Isolation (FDI) and Model-Based Diagnosis (MBD) methods. In some practical applications, however, building and validating such models may not always be possible, or only partially validated models can be obtained. In this paper we present a diagnosis solution when only a partially validated model is available. The solution uses a fault-aug...

Driven by requests from Internet-savvy students, a large number of universities and educational institutions have started to design, develop and use information and communication technology to create, share and disseminate instructional material. Commercial tools, such as Blackboard and WebCT, are available to offer basic course management functionalities. However, most of these tools are hinde...

The efficiency with which incoming photosynthetically active radiation (PAR) is intercepted by a canopy depends on the proportions of diffuse and direct radiation in the incoming PAR. In the present work, we developed a comparison between two spectral cloudless sky parameterization schemes in terms of their capability to provide accurate estimates of global, diffuse and direct incoming PAR. Bot...

In this paper we present a rule-based system for automatic extraction of definitions from Portuguese texts. As input, this system takes text that is previously annotated with morpho-syntactic information, namely on POS and inflection features. It handles three types of definitions, whose connector between definiendum and definiens is the so-called copula verb “to be”, a verb other that one, or ...

This paper presents a system for video shot retrieval in which shots are retrieved based on matching video objects using a combination of colour, shape and texture. Rather than matching on individual objects, our system supports sets of query objects which in total reflect the user’s object-based information need. Our work also adapts to a shifting user information need by initiating the partit...

Just how different are objects and agents? Some developers consider agents to be objects, but with more bells and whistles. This approach tends to define agents beginning with the phrase, "An agent is an object that ..."—where the definers add their favorite discriminating features. Then, there are those who see agents and objects as different even though they share many things in common. Both ...
