Topic: Categorization

In the News (Fri 24 May 19)

  Categorization - Meta
There are several proposals for how to do categorization in Wikimedia sites (and, by extension, for other MediaWiki sites).
See Categorization requirements for some abstract requirements for categorization in MediaWiki.
Magnus Manske did an automated categorization tool using a "Category:" pseudo-namespace.

  Test Categorization Techniques with TestNG
TestNG is an annotation-based testing framework, which draws on some of the shortcomings of JUnit by adding features such as flexible fixtures, test categorization, parametric testing, and dependent methods, to name a few.
Plus, the aggregate time to execute a test suite has the tendency to lengthen when there are extensive set-up steps, such as configuring a database or deploying an EAR file, to name a few.
Categorizing tests, however, requires that we define specific categories, which means refining the generic term unit tests.

Categorization: how we divide our world up into groups, or conceptual classes.
(1) The purpose of categorization is to reduce the infinite differences among stimuli.
There is one level of categorization at which most judgments are made.

 Principles of Categorization
The principles of categorization proposed are not as such intended to constitute a theory of the development of categories in children born into a culture nor to constitute a model of how categories are processed (how categorizations are made) in the minds of adult speakers of a language.
The second principle of categorization asserts that unlike the sets of stimuli used in traditional laboratory concept attainment tasks, the perceived world is not an unstructured total set of equiprobable co-­occurring attributes Rather, the material objects of the world are perceive to possess (in Garner's, 1974, sense) high correlational structure.
The implication of the principles of categorization for the horizontal dimension is that to increase the distinctiveness and flexibility of categories, categories tend to become defined in terms of prototypes or prototypical instances that contain the attributes most representative of items inside and least representative of items outside the category.

 EPA > Wetlands > Wetlands Fact Sheet > Wetlands Categorization
Categorization proponents believe wetlands regulation would be improved by focusing agency resources on protection of the most valuable wetlands.
Categorization proponents also believe this approach could provide greater consistency and predictability in the permit review process and reduce regulatory burden for activities in lower value wetlands.
It has been found that categorization works most effectively in the context of local or regional watershed planning initiatives where the relative value of wetlands within the context of a particular watershed can be more accurately assessed.

 BioMed Central | Full text | A MEDLINE categorization algorithm
Categorization is designed to enhance resource description by organizing content description so as to enable the reader to grasp quickly and easily what are the main topics discussed in it.
Categorization is designed to enhance resource description by organizing content description so as to enable the reader to grasp quickly and easily what a resource is about, what are the main topics discussed in it.
For 63% of the resources, the automatic categorization was rated by the medical librarian as "fully relevant" or "fairly relevant" (whereas 20% of the resources were "partially relevant" and 22% of the resources were "non-relevant").

 Visual Categorization in Pigeons
Categorization can be viewed as the ability to treat similar, but not identical, things as somehow equivalent, by sorting them into their proper categories and by reacting to them in the same manner (Rosch, 1978; Medin and Smith, 1984; Harnard, 1987; Neisser, 1987).
It would lead to a regrettable underestimation of their competencies if they were interpreted as simple categorization and, at the same time, to an overestimation of the distinctiveness of those processes that give rise to the bottleneck solutions found in many other species.
Despite the common tenet that categorization is not a logical device, but a matter of assessing similarity, there is little agreement concerning the level of abstraction from which the descriptors of open-ended categories are obtained.

 An Adaptive Approach to Text Categorization and Understanding--A Preliminary Study
Categorization of electronic documents is discussed and the results of a preliminary study of techniques that people use for categorizing electronic mail letters are presented.
Categorization is a problem that cognitive psychologists have dealt with for many years [2][8].
Automatic categorization may be used to organize relatively unstructured documents and make it easier to use other methods of creating and presenting the documents, e.g., associative methods such as hypertext, which are more natural to a user [3][9].

 Literature on Categorization
Categorization is not a matter to be taken lightly.
This sometimes leads to the impression that we just categorize things as they are, that things come in natural kinds, and that our categories of mind naturally fit the kinds of things there are in the world.
Categorization has moved from the background to center stage because of empirical studies in a wide range of disciplines.

 Automatic Categorization
Autonomy's infrastructure relies on an elegant pattern matching process based on concepts to categorize documents and automatically insert tag data sets, route content or alert users to highly relevant information pertinent to the users profile.
This highly efficient process means that Autonomy is able to categorize upwards of four million documents in 24 hours per CPU instance, that's approximately one document, every 25 milliseconds.
Automatic categorization enables the News feed provider to control the exponential growth of Information allowing data to be consistently categorized and structured in a clear logical taxonomy, improving knowledge provision.

 Taxonomies, Classification, Categorization - SearchTools.com Report
In Categorization and Visualization, they feel that InXight is the best among a field that includes Antarctica, Applied Semantics, ClearForest, IBM Lotus Discovery, Mohomine, Entrieva (Semio), Stratify and The Brain.
Describes the value of standards for categorization, and the value of RDF and other standards which describe the most important terms and categories for a document.
Most interesting is the evaluation of how well the categorization performed compared to human classifiers.

Unlike in recognition, where the problem is to identify a view of a previously seen object as such, in categorization the ``correct'' outcome of the process is ill-defined (and, a fortiori, cannot be included in a training set for a function approximation module).
In recognition, the different views of the same object, under appropriate encoding, can be shown to lie on a smooth hypersurface; in contrast, in categorization nothing can be said in general regarding the locus of points corresponding to arbitrary shapes in the space of all possible shapes.
Because of these problems, the standard approach to the understanding of the human performance in shape categorization has been to postulate the recovery of stimulus geometry prior to any processing --- including recognition [Marr, 1982].

 Concepts categorization in concept maps
Categorization has a fundamental role in learning design (a function that is already present in very little children), and therefore has a first order role in knowledge representation, in concept maps/semantic networks construction and analysis.
Categorization is a central topic in cognitive psychology, in linguistics, and in philosophy, but it is crucial precisely in learning.
Concepts categorization enables the student to classify (or to recognize the classification of) objects or concepts that belong to a group.

 The Importance of Metadata: Reification, Categorization, and UDDI   (Site not responding. Last check: )
The downside of unchecked categorization is that the UDDI Server may not be able to display to the user values that are appropriate for that category system.
While the mechanism for creating unchecked categorization schemes is identical to the process of the UBR (simply saving a tModel and advertising its usage), the mechanism for supporting checked taxonomies is enhanced significantly.
Classification and typed metadata is key to the ability of UDDI to solve the problems of reification of data both in the enterprise and in the public sphere.

 Journal of Biomedical Discovery and Collaboration | Full text | The TREC 2004 genomics track categorization task: ...
One subtask of the categorization task required the triage of articles likely to have experimental evidence warranting the assignment of GO terms, while the other two subtasks were concerned with the assignment of the three top-level GO categories to each paper containing evidence for these categories.
The documents for the categorization task consisted of articles from three journals over two years, reflecting the full-text documents we were able to obtain from Highwire Press http://www.highwire.org.
These were distributed across the subtasks of the categorization task as follows: 59 for the triage subtask, 36 for the annotation hierarchy subtask, and three for the annotation hierarchy plus evidence code subtask.
