- FORMALLY MODELING CAUSE AND EFFECT: PART II
by Ed Colet
- Executive Editor-at-Large Inderpal Bhandari presents a guest editorial by
Virtual Gold's Acting Director of Research:
- Many data mining algorithms for detecting patterns rely upon finding
associations and dependencies among the many attributes that can exist in a
large dataset. But because a correlation does not imply causation, it can be
difficult to determine the nature of a causal relationship (or if one even
exists) between the attributes. Last week's column addressed the formal
computations for a correlation, and current approaches to investigate
causality. In this week's column, I describe some new research outlining the
limitations of current formalisms in modeling causality -- and progress
towards modeling causality with a better degree of mathematical precision.
- DIMENSIONAL OBJECT MODELING
by Joseph M. Firestone, Ph.D.
- An object modeling approach offers advantages in supporting Dimensional
Data Modeling (DDM) of data warehouses and data marts. The current approach
to making the basic decisions in producing a DDM is a pragmatic one. The
pragmatic approach has had considerable commercial success [1], but it still
makes tight coupling of strategic goals and objectives to the DDM result a
matter of art, rather than a product of an explicit method or procedure,
results in a model composed of passive containers for data attributes,
rather than components that combine both data and behavior, does not place
DDM within a broader framework for integrating data and process -- that is,
the pragmatic approach is too data-centric, at a time when data warehousing
is concerned with integrating a complex diversity of server-based decision
support system functions.
- TEXT MINING BY FILTER COMPOSITION
by Inderjeet Mani, et al, Mitre
- We all have access to lots of information, but are seldom in a position to
exploit it effectively for decision making. In times of crisis, this problem
can be especially severe.
