TL;DR: The need to create order from the nearly unthinkably huge streams of data which are beginning to appear presents the greatest challenge and opportunity for astronomical classification in more than a generation.

Abstract: Astronomers have used classification methods as tools in examining the nature of the universe for more than a century. Classification remains a very heavily used tool in many subfields of astronomy. The development of new and very powerful classification technologies, the development of enormously increased computing capacity, and the development of a new generation of areal and multi-object digital detectors are creating a substantially changed situation. For the first time since the invention of the photographic plate technological change is forcing a major revision in the methods used to reduce data. The need to create order from the nearly unthinkably huge streams of data which are beginning to appear presents the greatest challenge and opportunity for astronomical classification in more than a generation.

A cognitive system for astronomical image interpretation
TL;DR: A dynamic network is presented which merges three separate technologies: statistical model fitting, from astronomy; syntactic descriptors, from pattern recognition; and synthetic human judgment, from descriptive psychology for automating galaxies by morphological type.

TL;DR: Two forms of data massaging, domain-independent and domain-specific, are distinguished and a new framework is outlined for the former, and the importance of the latter is illustrated in the context of two new, complex classification problems in astronomy.

TL;DR: A preliminary discussion of recent results obtained as part of the extension of the Center of Astrophysics redshift survey can be found in this article, where it appears that the galaxies are on the surfaces of bubble-like structures with diameters of 25-50/h-Mpc.

The Distribution of rich clusters of galaxies
TL;DR: In this article, a catalogue of 2712 rich clusters of galaxies found on the National Geographic Society-Palomar Observatory Sky Survey is presented, and 1682 clusters are selected which meet specific criteria for inclusion in a homogeneous statistical sample.
