Top-k Searching for More Users in Multidimensional B-tree with Lists

In the last few years, research of top-k processing is in progress in various domains. The aim of our research is efficient top-k searching of the best k objects preferences based on fuzzy functions. In ou...

Learning user preferences for top-k querying - improving learning of the higher ranked objects

In this paper we deal with user preference learning to enable top-k querying. Input for learning is user overall rating of a sample set of objects. We introduce a new method which favours the higher rated objects. We present a metho...

A description logic with concept instance ordering and top-k restriction

We present a new model of description logic where concepts are ordered sets. This is useful for describing concepts where only top-k objects appear. We solve basic problems......

On supporting wide range of attribute types for top-k search

Searching top-k objects for many users face the problem of different user preferences. The family of Threshold algorithms computes top-k objects using sorted access to ordered lists. Each list is ordered w.r.t. use...

On top-k retrieval for a family of non-monotonic ranking functions

We presented a top-k algorithm to retrieve tuples according to the order provided by a non-necessarily monotone ranking funtion that belongs to a novel family of functions. The conditions imposed on the ranking functions are related...

Learning Different User Profile Annotated Rules for Fuzzy Preference Top-k Quering

We consider uncertainty querying of large data for top-k answers. Main goal of this paper is to assign a user a preference model automatically. To solve the problem we design two algorithms. Methods were integrated into a top

Verification of Top-k algorithm for a family of non-monotonic ranking function

We present a top-k algorithm for retrieving tuples according to the order provided by a ranking function that belongs to a subclass of non-monotonic functions. The ranking functions are defined with the values where the maximum scor...
