This paper presents a theoretical approach to the characterization of requests boundaries and structure in general spoken dialogue. Emphasis is laid on the fracture between the illocutionary act of requesting (for which the term ‘request’ is kept) and the locutionary elements that carry it out (its ‘instantiation’). This approach leads to a representation of requests based on the inclusion of a...

Ensuring fairness in a system with scarce, preferred resources requires time sharing. We consider a heterogeneous system with a few “big” and many “small” processors. We allocate heterogeneous processors using a novel token mechanism, which frames the allocation problem as a repeated game. At each round, users request big processors and spend a token if their request is granted. We analyze the ...

This paper explores various strategies for enhancing the reliability of pseudo-relevance feedback using TREC and NTCIR test collections. For each test request, the number of pseudo-relevanct documents ( ) or the number of expansion terms ( ) is determined based on a similar training request (i.e. via direct mapping) or a group of similar training requests (i.e. via categorization). The results ...

Web proxies and Content Delivery Networks (CDNs) are widely used to accelerate Web content delivery and to conserve Internet bandwidth. These caching agents are highly e ective for static content, which is an important component of all Web-based services. This paper explores the e ect of ubiquitous Web caching on the request patterns seen by other components of an end-to-end content delivery ar...
