Preference-Based Recommendations for OLAP Analysis

Research Directions of OLAP Personalizaton

“…The concept of Visual OLAP is disburdening the user from composing queries in "raw" database syntax (SQL, MDX), whereas events like clicking and dragging are transformed into valid queries and executed [7]. In [5,6,11] authors present a user interface for OLAP, where user is explicitly involved. In [6] users are able to navigate in dimensional hierarchies using a schemabased data browser, whereas in [5,11] users are provided with an interface for formulating queries by means of manipulation with graphical OLAP schema and rules.…”

The query is composed by the user when he/she selects a measure and an aggregation function [6].…”

“…RUPA approach is presented in [5], where a context-based method for providing users with recommendations for further exploration is proposed. An analysis context includes two disjoint set elements (i.e.…”

“…OLAP recommendation techniques are proposed in [4] and [5]. In [4] former sessions of the same data warehouse user are being investigated.…”

“…In [4] former sessions of the same data warehouse user are being investigated. User profiles that contain user preferences are taken into consideration in [5], while generating query recommendations.…”
