Contents

What is this all about? The aim of this sub-project is to assess Systems articles for their quality and importance (or priority), and to classify them broadly by field. These ratings are intended to help the project track its progress, identify weak spots in its coverage, and highlight articles which could become Good Articles or Featured articles. They also link with the Wikipedia 1.0 project to produce a CD-ROM with the best of Wikipedia, and similar ratings are used by over 100 WikiProjects.

[edit] Summary table

The following table, along with the subpages it links to, summarizes information about the articles that have been assigned ratings.

[edit] How to assess articles

Any article can be assessed for its systems content and anybody can assess an article simply by adding the {{sys rating}} tag to the article's talk page and filling in the class, importance and field parameters (see below). These ratings can be modified by all editors, with disputes discussed on the article's talk page. The most important component of this assessment is the quality of the article, given by the class parameter. If this parameter is omitted, the {{sys rating}} tag will place the article in the unassessed category, which is a signal for other editors to grade its quality.

For the most part, the quality criteria for articles in this project follow the WP 1.0 assessment; however there is also an additional B+ quality grading for articles which are very close to the GA (Good Article) standard and have a good layman's explanations, history and illustrations.

The articles which have been assessed by field (the area of Systems in which they broadly belong) can be found in subpages linked by the {{WP SYS 1.0}} banner above.

The overall summary of systems articles by quality can be found at

Wikipedia:Version 1.0 Editorial Team/Systems articles by quality

and a log of new ratings and changes can be found at

Wikipedia:Version 1.0 Editorial Team/Systems articles by quality log.

[edit] The {{sys rating}} template

To classify an article, place the template {{sys rating}} on the article's talk page. Anyone can add a sys rating or change an existing rating. The template can be used to assess the importance (or priority) and quality (or class grading) of the article using the importance and class parameters respectively. Specifying these parameters will place the article in the appropriate subcategory of Category:Systems articles by importance and Category:Systems articles by quality. There is also a field parameter to define the subject area of the article.

The (reduced) syntax of the sys rating template is:

{{sys rating 
 |nested=
 |class=
 |importance=
 |field=
 }}
  • nested=yes can be used when nested with other compliant projects inside a {{WikiProjectBannerShell}}
  • small=yes can be used when a page has lots of templates, producing a more compact version. Any other value for small parameter is ignored, and the standard template results.
  • class must be one of:
    FA (for Featured Articles only)
    A (for A-class articles only)
    GA (for Good Articles only)
    Bplus
    B
    Start
    Stub
    Dab (mathematical disambiguation pages)
    Cat (Systems categories)
    Image (Systems images)
    Template (Systems templates)
  • importance must be one of:
    Top
    High
    Mid
    Low
    NA (for non-articles only)
The synonym priority is also available for the importance parameter.
  • field must be one of:
    Chaos theory
    Cybernetics
    Control theory
    Dynamical systems
    Dynamical systems
    Scientific modeling
    Systems
    Systems biology
    Systems ecology
    Systems engineering
    Systems psychology
    Systems theory (general information about Systems theory not related to a particular field)

Comments may be left in the /Comments subpage of the article talk page (for example, Talk:Abacus/Comments). These brief comments usually contain suggestions on how the article could be improved to bring it up to the next grade. It is helpful to at least put ~~~~ as a comment, so that the date of the rating can easily be seen. Comments can be added by following the "Add comments" link on the template, and may edited by following the "Comments" link on the template.

If either class or importance is missing, then the article will be placed in Category:Unassessed quality Systems articles or Category:Unassessed importance Systems articles respectively. If field is missing, then the article will be placed in Category:Unassessed field Systems articles.

[edit] Assessment summary and list of fields

Summary of {{sys rating}} importance, field, and class parameters
Importance: the importance (or priority) of the article/subject, regardless of its quality. Field: the article's subject area within Systems. Class: the current quality of the article.
Top Extremely important, even crucial, to its field, and very significant beyond it Featured article FA This is a featured article.
High Contributes a substantial depth of knowledge with significant impact in other fields A Essentially complete, well written and referenced; possible featured article candidate.
Mid Adds important further details within its field, with some impact beyond it Good article GA B+ quality, and also a good article.
Low Contributes more specific or less significant details, or is mainly of specialist interest A-BB+ Detailed, clear and accessible, often with history or images; possible good article nominee.
B A decent article, but it needs further editing to extend coverage or accessibility
Start Significant cleanup or expansion needed.
Stub Article has very little content, or is a stub.

[edit] Quality grading scheme

A more extensive description of the quality grading criteria is given in the table below. This is based on the WP 1.0 Assessment.

[edit table]
Quality Criteria Reader's experience Examples
Editor's experience
Featured article FA
{{FA-Class}}		 Reserved exclusively for articles that have received featured article status after peer review, and meet the current criteria for featured articles. Definitive. Outstanding, thorough article; a great source for encyclopedic information. Trigonometric function (Mar 2, 2007)

Leonhard Euler (Mar 2, 2007)
No further editing is necessary unless new published information has come to light; but further improvements to the text are often possible.
A
{{A-Class}}		 Provides a well-written, reasonably clear and complete description of the topic, as described in "How to write a great article". It should be of a length suitable for the subject, with a well-written introduction and an appropriate series of headings to break up the content. It should have sufficient external literature references, from text-books or peer-reviewed papers, rather than websites. Should be well illustrated, with no copyright problems. At the stage where it could at least be considered for featured article status; corresponds to the "Wikipedia 1.0" standard. Very useful to readers. A fairly complete treatment of the subject. A non-mathematician would typically find nothing wanting. May miss a few relevant points. Fermat's last theorem (Mar 2, 2007)

Regular polytope (Mar 2, 2007)
Manifold (Mar 2, 2007)
Minor edits and adjustments would improve the article, particularly if brought to bear by a subject-matter expert. In particular, issues of breadth, completeness, and balance may need work. Peer-review would be helpful at this stage.
Good article GA
{{GA-Class}}		 This class is for articles of B+ quality which have also passed through the good article nomination process and meet the good article standards. Note that the good article designation is not a requirement for A-Class. A-Class articles which meet good article standards should be considered for featured article status. As good as a B+ article, but may also have more polished presentation, more illustrations, more detailed history, and more references. Euclidean geometry (Mar 2, 2007)

Ordinal number (Mar 2, 2007)
Homotopy groups of spheres (Mar 2, 2007)
Further editing will clearly be helpful, but not necessary for a good reader experience.
A-BB+
{{Bplus-Class}}		 The article has most of the elements described in "start" and may be regarded as a complete article. It is broad in its coverage, while staying focussed on the topic; it is factually accurate, verifiable and neutral; and it is well presented, both in terms of grammar, and adherence to some of the main points in the manual of style. The article is well-referenced, and is illustrated, where appropriate, by an image or images which comply with copyright guidelines. It has the potential to become a good article. Among Systems articles these are some of the best; however, Wikipedia 1.0 does not currently have a B+-Class. Useful to nearly all readers. A good treatment of the subject which attempts to be as accessible as possible, with a minimum of jargon. No obvious problems, gaps, excessive information. René Descartes (Mar 2, 2007) Introduction to general relativity (Mar 2, 2007)
May be improved by input from experts to assess where coverage is still missing, and also by illustrations, historical background and further references. Consider peer review or nominating for good article status. If the article is not already fully wikified, now is the time.
B
{{B-Class}}		 The article has several of the elements described in "start", and usually a majority of the material needed for a complete article. Nonetheless, it has significant gaps or missing elements or references, needs substantial editing for English language usage and/or clarity, balance of content, or contains other policy problems such as copyright, neutral point of view (NPOV) or no original research (NOR). With NPOV a well written B-class may correspond to the "Wikipedia 0.5" or "usable" standard. Articles that are close to GA status but don't meet the good article criteria should be B- or B+-Class articles. Useful to many, but not all, readers. An interested reader flipping through the article may feel that they generally understood the topic. However, it may not be as accessible as as it could be, or it may be inadequate for a serious student or researcher trying to use the material, who might have trouble or risk error using the article in derivative work. Set (Mar 2, 2007)
Limit (Systems) (Mar 2, 2007)
Vector space (Mar 2, 2007)
Considerable editing is still needed, including filling in some important gaps or correcting significant policy errors. Articles for which cleanup is needed will typically have this designation to start with.
Start
{{Start-Class}}		 The article has a meaningful amount of good content, but it is still weak in many areas, and may lack a key element such as a standard infobox. For example an article on groups might cover the theory well, but be weak on history and motivation. Has at least one serious element of gathered materials, including any one of the following:
  • a particularly useful picture or graphic
  • multiple links that help explain or illustrate the topic
  • a subheading that fully treats an element of the topic
  • multiple subheadings that indicate material that could be added to complete the article
 Useful to some, provides a moderate amount of information, but many readers will need to find additional sources of information. The article clearly needs to be expanded. Hypergraph (Mar 2, 2007)
Esther Szekeres (Mar 2, 2007)
Theorem (Mar 2, 2007)
Substantial/major editing is needed, most material for a complete article needs to be added. This article still needs to be completed, so an article cleanup tag is inappropriate at this stage.
Stub
{{Stub-Class}}		 The article is either a very short article or a rough collection of information that will need much work. It is usually very short, but can be of any length if the material is irrelevant or incomprehensible. Possibly useful to a mathematician who has no idea what the term meant. May be useless to a non-mathematician, or a reader only passingly familiar with the term. Ideally it is at least a brief, informed definition. Selig Brodetsky (Mar 2, 2007)
Parallel curve (Mar 2, 2007)
Algebraic number theory (Mar 2, 2007)
Any editing or additional material can be helpful.

[edit] Articles to include

The prioritization of Systems articles has been motivated by: articles highlighted in Systems; those linked from Portal:Systems#Topics in Systems; a selection of the most linked-to systems articles (see talk page); Wikipedia:Vital_articles#Systems; and anything else an editors felt should be included as important.

The lists of articles have split into subpages organised by systems field, and are linked via the navigation box at the top and bottom of this page. (The exceptions are the "Core" articles, detailed below.) The lists are not meant to be exhaustive or definitive and editors are encouraged to make additions.

[edit] Core Articles

Article Need Rationale Links Quality Comments
Systems Top WP:CORE. Our top-level article 6487 A Also a good article
Algebra Top WP:CORE B Only history, classes, meanings, no examples
Geometry Top WP:CORE 979 B Needs refs, C20th section
Information Top WP:CORE also covered by Information technology 664 B Needs a lot of work
Logic Top WP:CORE also covered by Philosophy 1300+ A-BB+ Very good but needs a pic or two. Short but OK
because many sub-pages e.g. Mathematical logic
Mathematical proof Top WP:CORE (originally as Proof theory) 250 Start
Measurement Low WP:CORE Not really our domain as covered by Science 700+ Start Needs much more, e.g. errors,
precision vs. accuracy, sig figs etc
Number Top Listed in WP:CORE 400+ A Former GA, 4/13/06 - This has been removed from the GA list.
Statistics Top WP:CORE 1164 A-BB+ Former GA, see the reasons. Could use more background/historical information
