An Interval-Like Scale Property for I. R. Evaluation Measures
نویسندگان
چکیده
Evaluation measures play an important role in IR experimental evaluation and their properties determine the kind of statistical analyses we can conduct. It has been previously shown that it is questionable that IR effectiveness measures are on an interval-scale and this implies that computing means and variances is not a permissible operation. In this paper, we investigate whether it is possible to relax a bit the denition of interval scale, introducing the notion of intervallike scale, and to what extent IR eectiveness measures comply with this relaxed denition.

DEA Models with Interval Scale Inputs and Outputs
This paper proposes an alternative approach for efficiency analysis when a set of DMUs uses interval scale variables in the productive process. To test the influence of these variables, we present a general approach of deriving DEA models to deal with the variables. We investigate a number of performance measures with unrestricted-in-sign interval and/or interval scale variables.
متن کاملAsymptotic behaviour of associated primes of monomial ideals with combinatorial applications
Let $R$ be a commutative Noetherian ring and $I$ be an ideal of $R$. We say that $I$ satisfies the persistence property if $mathrm{Ass}_R(R/I^k)subseteq mathrm{Ass}_R(R/I^{k+1})$ for all positive integers $kgeq 1$, which $mathrm{Ass}_R(R/I)$ denotes the set of associated prime ideals of $I$. In this paper, we introduce a class of square-free monomial ideals in the polynomial ring $R=K[x_1,ld...
متن کاملPhilosophical Approach to Autonomy and a scale for Measuring Ethical Autonomy of Public Librarians
Purpose: in this article I tried to construct a new scale for measuring ethical autonomy of public librarians by rereading and reinterpreting the reflections of ethical philosophers on the concept of autonomy. Methodology: this research implemented in two phases. In the phase 1, I used documentary research method and conceptual analysis approach to find and analyze key ideas of philosophers. B...
متن کاملA NEW PROOF OF THE PERSISTENCE PROPERTY FOR IDEALS IN DEDEKIND RINGS AND PR¨UFER DOMAINS
In this paper, by using elementary tools of commutative algebra,we prove the persistence property for two especial classes of rings. In fact, thispaper has two main sections. In the first main section, we let R be a Dedekindring and I be a proper ideal of R. We prove that if I1, . . . , In are non-zeroproper ideals of R, then Ass1(Ik11 . . . Iknn ) = Ass1(Ik11 ) [ · · · [ Ass1(Iknn )for all k1,...

A topoframe, denoted by $L_{ tau}$, is a pair $(L, tau)$ consisting of a frame $L$ and a subframe $ tau $ all of whose elements are complementary elements in$L$. $f$-ring $mathcal{R}(L_{ tau})$ is equal to the set $${fin Frm(mathcal{P}(mathbb R), L): f(mathfrak{O}(mathbb R))subseteq tau} .$$ In this paper, for every complemented element $ain L$ with $a, a'...
