An axiomatic approach for result diversification
2009
Proceedings of the 18th international conference on World wide web - WWW '09
Preserved Fulltext
In analogy to prior work on ranking and clustering systems, we use the axiomatic approach to characterize and design diversification systems. ...
We also uncover a rich link to the facility dispersion problem that results in algorithms for a number of diversification objectives. ...
Acknowledgments We would like to thank Kunal Talwar for helpful discussions, and Panayiotis Tsaparas for providing data and helping us with the classification of product queries. ...

We then apply axiomatic approaches to derive a structural diversification method that can leverage the subtopic relations in result diversification. ...
Experimental results over an enterprise collection show that the relations among query subtopics are useful to improve the diversification performance. ...
We then use an axiomatic approach to derive a structural similarity function for subtopics based on their structural relations on the con-cept hierarchy. ...

This article provides mathematically and economically sound choice theoretic foundations for the naive approach to diversification. ...
We axiomatize naive diversification by defining it as a preference for equality over inequality, derive its relationship to the classical diversification paradigm, and provide a utility representation. ...
Axiomatically, preference for diversification is formalized as follows; see Dekel (1989) . Definition 4 (Preference for diversification). ...

We axiomatize naive diversification by defining it as a preference for equality over inequality and derive its relationship to the classical diversification paradigm. ...
The goal of our choice-theoretic approach is threefold: First, by developing an axiomatic system for what is considered to be an "irrational" choice paradigm such as naive diversification, we can justify ...

Within the theory of choice, desirability of diversification is axiomatized as preference for a convex combination of choices that are equivalently ranked. ...
This paper analyzes axiomatizations of the concept of diversification and their relationship to the related notions of risk aversion and convex preferences within different choice theoretic models. ...
An immediate consequence of this result is that convexity of preferences, or equivalently preference for diversification, implies strong risk aversion. ...

Starting from the respective axiomatic definitions, we prove that a class of proper measures of connectedness verifies, after a suitable functional transformation, the axiomatic requirements for a measure ...
In this paper we propose a theoretical approach to bring to light the relation between connectedness and diversification. ...
Recently, an attempt to formalize the concept of connectedness through an axiomatic approach has been proposed in Maggi et al. [18] . ...

In this paper we propose an axiom system for capital allocation and analyze its satisfiability and completeness: it is shown that for a given risk measure ρ there exists a capital allocation Λ ρ which ...
We apply the axiomatization to the most popular risk measures in the finance industry in order to derive explicit capital allocation formulae for these measures. ...
The following definition formalizes these principles (see Denault (2001) for an alternative axiomatic approach). DEFINITION 2.1. Let ρ : V → R. ...
