Imprecise Data and Knowledge Based OLAP
نویسندگان
چکیده
In this paper we present our approach for extending the OLAP model to include treatment of value uncertainty as part of a multidimensional model inhabited by flexible data and non-rigid hierarchical structures of organisation. A new multidimensional-cubic model named as the IF-Cube is introduced which is able to operate over data with imprecision either in the facts or in the dimensional hierarchies.

OLAP over Imprecise Data with Domain Constraints
Several recent works have focused on OLAP over imprecise data, where each fact can be a region, instead of a point, in a multidimensional space. They have provided a multiple-world semantics for such data, and developed efficient solutions to answer OLAP aggregation queries over the imprecise facts. These solutions however assume that the imprecise facts can be interpreted independently of one ...
متن کاملTowards Fuzzy-OLAP Mining
Multidimensional databases and OLAP (On Line Analytical Processing) tools provide an eÆcient framework for data mining and have led to the so-called OLAP Mining architecture ([10]). Besides, data from real world are often imperfect, either because they are uncertain, or because they are imprecise. Moreover, the use of fuzzy set theory in data mining systems enhances the understandability of the...
متن کاملEvaluation and selection of sustainable suppliers in supply chain using new GP-DEA model with imprecise data
Nowadays, with respect to knowledge growth about enterprise sustainability, sustainable supplier selection is considered a vital factor in sustainable supply chain management. On the other hand, usually in real problems, the data are imprecise. One method that is helpful for the evaluation and selection of the sustainable supplier and has the ability to use a variety of data types is data envel...
متن کاملSupporting Imprecision in Multidimensional Databases Using Granularities
On-Line Analytical Processing (OLAP) technologies are being used widely, but the lack of effective means of handling data imprecision, which occurs when exact values are not known precisely or are entirely missing, represents a major obstacle in applying these technologies in many domains. This paper develops techniques for handling imprecision that aim to maximally reuse existing OLAP modeling...
متن کاملEfficient Algorithms for Allocation Policies
Recent work [2] proposed extending the OLAP data model to represent data ambiguity. Specifically, one form of ambiguity that work addressed arose from relaxing the assumption that all dimension attributes in a fact are assigned leaf-level values from the underlying domain hierarchy. Such data was referred to as imprecise. Allocation was proposed by [2] as a mechanism to deal with imprecision. I...
