"... In PAGE 3: ... These models include the Dimensional- Fact (DF) model by Matteo Golfarelli and colleagues,5 the Multidimensional/Entity-Relationship (M/ER) model by Carsten Sapia and colleagues,10,11 and the StarEr model by Nectaria Tryfona and colleagues.7 Table1 shows the multidimensional properties of these three types of conceptual models. Only the StarEr model considers the many-to-many relation- ships between facts and particular dimensions by indi- cating the exact cardinality between them.... ..."

in Applying UML and XML for Designing and Interchanging Information for Data Warehouses and OLAP Applications
by Juan Trujillo, Sergio Luján-mora, Il-yeol Song 2004
"... In PAGE 7: .... In Table1 , we provide the coverage degree of each above-mentioned conceptual model regarding the main MD properties described in the previous section. To start with, to the best of our knowledge, no proposal provides a grouping mechanism to avoid flat diagrams and to simplify the conceptual design when a system becomes complex due to a high number of dimensions and facts sharing dimensions and their corresponding hierarchies.... In PAGE 8: ... On the other hand, only the M/ER model provides a framework for an automatic generation of the database schema into a target commercial OLAP tool (particularly into Informix Metacube and Cognos Powerplay). Finally, none of the proposals from Table1 provide a mechanism to facilitate the interchange of the models following standard representations. Regarding MD modeling and the eXtensible Markup Language (XML) (W3C, 2000), some proposals have been presented.... In PAGE 8: ... However, these approaches focus on the presentation of the multidimensional XML data rather than on the presentation of the structure of the multidimensional conceptual model itself. From Table1 , one may conclude that none of the current conceptual modeling approaches consider all MD properties at both the structural and dynamic levels. Therefore, we claim that a standard conceptual model is needed to consider all MD modeling properties at both the structural and dynamic levels.... ..."

"... In PAGE 17: ... Results. Table6 presents the M2-PLM results for O1, O2, O3, and EFA. For EFA, the obtained estimated correlations between the two factors, the obtained partitioning according to the two-factor solution, three t measures 2p values RMSR lt; .... In PAGE 17: ...2p values RMSR lt; .05 y and gt; :05 or RMSEA gt; .06 z are given. In general, O1 and O2 yielded the true dimensionality more often for the M2-PLM data than for the mixture model data (see Table6 ). In particular, for moderate discrimination, AS3, and r = :7, the obtained differences are noteworthy.... In PAGE 17: ... As expected, the O1, O2, and O3 values increased as the Distribu- tion of Dif culty increased. EFA generally yielded the same dimensionality solutions as O1 and O2 (see Table6 ). The Pro- max rotated two-factor model did not t well for r = :7, AS3, N = 200, and unbalanced data.... ..."

"... In PAGE 6: ... We set our baseline model at the (0; 0; 0) point of the coordinate-system and com- pared its performance to a simple treebank PCFG and to di erent combinations of parameters. Table5 shows the accuracy results for parsing section 0 for all models. The rst outcome of our experiments is that our head-driven baseline performs slightly better than a vanilla treebank PCFG.... ..."
