In contrast to XML query languages as e.g. XPath which require knowledge on the query language as well as on the document structure, keyword search is open to anybody. As the size of XML sources grows rapidly, the need for efficient search indices on XML data that support keyword search increases. In this paper, we present an approach of XML keyword search which is based on the DAG of the XML d...

Theories and tools to measure the efficiency of neural codes have been important in understanding neural responses to external stimuli. However, similar principles to describe the efficiency of brain responses to tasks demanding higher-order cognitive processes remain underdeveloped. A key domain to study such efficiency is learning, where patterns of activity across the entire brain provide in...

From the viewpoint of multilingual generation, the common underlying knowledge base should be kept clear of language-speciic concepts. This goal presupposes that lexical items of various languages cannot map one-to-one onto concepts all the time. We propose a more exi-ble way of attaching lexical items to conngurations of concepts and roles, and a lexical option nder that determines the set of ...

This paper critically examines Jerry Fodor’s latest attacks on evolutionary psychology. Contra Leda Cosmides and John Tooby, Fodor argues (i) there is no reason to think that human cognition is a Darwinian adaptation in the first place, and (ii) there is no valid inference from adaptationism about the mind to massive modularity. However, Fodor maintains (iii) that there is a valid inference in ...

We have developed a planner for redundant manipula-tors that is fast, eeective and versatile, based on the idea of treating each link of a rigid-linked robot as if it were slightly exible and under the innuence of a potential eld. We describe the extensions to the basic method that allow it to plan paths for manipulators with revolute joints (linear and spherical joints having been covered in a...
