Help:Term lookup

This is a help page, for term lookup.

Are you looking for the meaning of a particular term? The Subject Wikis Reference Guide can help you to look up definitions of terms, as well as all kinds of information about the term you're looking for.

A quick explanation of how we're organized

The subwiki.org domain contains a number of subject-specific wikis. Each subject-specific wiki has articles developed and organized from the viewpoint of a specific subject or discipline. As of now, all the subject-specific wikis are in mathematical subjects. Here's a list of all the subject-specific wikis.

Wiki	Main topic	Page count (lower bound)	Creation month	State of development	Content being added?	Error log	Pageview count (2016) (Google Analytics)	Quantcast?
Groupprops	Group theory	7200	December 2006	beta	Occasionally	here	931,796	Starting April 2, 2017

Commalg	Commutative algebra	400	January 2007	alpha	No	Not yet	13,287	No (pending data checking; might be too little data)

Demography	Demography	191	September 2013	alpha	No	Not yet	3,594	No (too little data)

NOTE: The creation month need not coincide with the month of MediaWiki installation. In cases where the wiki was ported from elsewhere, the creation month may be earlier; in other cases, it may be later if the first edits happened long after installation.

Pageview count note: Estimates are based on Google Analytics data, not based on MediaWiki internal logs, which record about 2-3X the pageviews recorded by Google Analytics.

The Subject Wikis Reference Guide is designed to let you reach, just from the name of a term, the appropriate subject wikis that contain that term.

Lookup when the term name is known

When the full term name is known

Any term which occurs in one or more of the subject-specific wikis (and sometimes, a term that doesn't) should have a reference guide page. The reference guide page for a term has the same name as the term. Thus, for instance, to get the reference guide page about normal subgroup, you'll need to type the following URL:

https://subwiki.org/wiki/Normal_subgroup

Alternatively, you can type normal subgroup (without quotes) in the search bar and press Enter (or the Go key). This will directly take you to the page titled "Normal subgroup".

When part of the term name is known

Suppose you don't know the full name of a term, but know that it is called "perfect something". Alternatively, suppose you're interested in all the possible uses of the word "perfect" in terminology in different subjects. Then, try searching for whatever part of the term you do know. For instance, in this case, you'll try the page:

https://subwiki.org/wiki/Perfect

or search for perfect in the search bar.

If you're interested in the use of the term in a particular subject (for instance, economics), then type the prefix or partial term, followed by the subject in parentheses. For instance, to see all the uses of the term "perfect" in economics, try:

https://subwiki.org/wiki/Perfect_(economics)

The generic page on Perfect includes the content from the pages on Perfect in each broad subject area, as sections. Further, the page on perfect (economics) includes content from the guide pages for each of the specific terms that have "perfect" in them.

Proceeding from the guide page=

The Subject Wikis Reference guide page to a particular term gives the following:

• A quick (and not necessarily comprehensive) definition, and common style of usage
• A list of related terms and ideas.
• A link to the primary subject wiki entry on the term (if such an entry exists). For instance, if you're looking for a term like "Hausdorff space", the Reference Guide page on it will tell you that the primary subject wiki entry is at Topospaces:Hausdorff space.
• Links to entries on the term in other subject wikis.
• Links to entries on the term in other encyclopedia-like web resources.

Textbook and journal references are maintained in the subject wiki entries and are not to be found on the reference guide page.
