Retrieval-Efficiency Trade-Off of Unsupervised Keyword Extraction

Unsupervised Keyword Extraction from Polish Legal Texts

In this work, we present an application of the recently proposed unsupervised keyword extraction algorithm RAKE to a corpus of Polish legal texts from the field of public procurement. RAKE is essentially a language and domain independent method. Its only languagespecific input is a stoplist containing a set of non-content words. The performance of the method heavily depends on the choice of suc...

Audio keyword extraction by unsupervised word discovery

In real audio data, frequently occurring patterns often convey relevant information on the overall content of the data. The possibility to extract meaningful portions of the main content by identifying such key patterns, can be exploited for providing audio summaries and speeding up the access to relevant parts of the data. We refer to these patterns as audio motifs in analogy with the nomencla...

The Equity/Efficiency Trade-off in Retrospect

Writing in 1975, Arthur Okun is generally credited with popularizing the idea of a “great tradeoff" between equity and efficiency. Indeed, a generation of economists has been brought up thinking that in the allocation of scarce resources to competing ends, the tradeoff between “equity” and “efficiency” is just another one of the many tough choices that economically rational individuals have to ...

On the Efficiency-Fairness Trade-off

T paper deals with a basic issue: How does one approach the problem of designing the “right” objective for a given resource allocation problem? The notion of what is right can be fairly nebulous; we consider two issues that we see as key: efficiency and fairness. We approach the problem of designing objectives that account for the natural tension between efficiency and fairness in the context o...
