Sensitivity Analysis for Declarative Relational Query Languages with Ordinal Ranks

We present sensitivity analysis for results of query executions in a relational model of data extended by ordinal ranks. The underlying model of data results from the ordinary Codd’s model of data in which we consider ordinal ranks of tuples in data tables expressing degrees to which tuples match queries. In this setting, we show that ranks assigned to tuples are insensitive to small changes, i...

Ordinal Ranks on Weakly Compact and Rosenthal Operators

Using the Schreier families (Sξ)ξ<ω1 , we define subclasses of weakly compact and Rosenthal operators between two Banach spaces. These subclasses give rise to ordinal ranks defined on each ideal. We prove several results concerning the analytic properties of this rank and give examples of spaces on which the ranks are bounded and unbounded.

Applications of Ordinal Ranks to Flexible Query Answering

Exact querying and retrieving relevant data from a database is a difficult task. We present an approach for flexibly answering algebraic queries using an extension of Codd’s relational model with ordinal ranks based on residuated lattices and similarities on attribute domains.

A Buchholz derivation system for the ordinal analysis of KP+Π3-reflection

In this paper we introduce a notation system for the infinitary derivations occurring in the ordinal analysis of KP + Π3-Reflection due to Michael Rathjen. This allows a finitary ordinal analysis of KP+Π3-Reflection. The method used is an extension of techniques developed by Wilfried Buchholz, namely operator controlled notation systems for RS-derivations. Similarly to Buchholz we obtain a char...

Canonical Analysis: Ranks, Ratios and Fits

Measurements of p variables for n samples are collected into a n x p matrix X, where the samples belong to one of k groups. In CVA, we aim to represent X as good as possible in an r-dimensional space. This can be done by optimising the so-called ratio form or via a constrained optimisation problem. When the within groups sum of squares matrix W is of full rank, both methods coincide. This is by...
