Accessing IMDb content from Wikipedia[edit]

Further information: Wikipedia:IMDb

A link to a page on IMDb about a title (a movie or a tv series), a person (actor, actress, etc.), a company, a character, or tv episode, can be made by means of five templates: {{imdb title}}, {{imdb name}}, {{imdb company}}, {{imdb character}}, and {{imdb episode}}. Instructions about the use of these templates can be found on their respective document pages. Note that these templates should be used in the "External links" section.

There is also another mean: using InterWiki by adding [[IMDbName:ID]] or [[IMDbTitle:ID]]. Just replace "ID" with the IMDb code (at the end of the URL) for a given title/person (eg. Frank Sinatra's is "0000069", and Ocean's Eleven is "0054135"). Example:

You can also make a piped link to use a text for the link:
  • [[IMDbName:0000069|Frank Sinatra]] is rendered as Frank Sinatra
  • [[IMDbTitle:0054135|''Ocean's Eleven'']] is rendered as Ocean's Eleven

This method should only be used where in-article links are needed. For the external links, the use of the imdb name, title, or company templates is preferred.

"Naming"[edit]

Does anyone have info about why imdb choose western naming name for chinese/korean actor/actress? like ng man tat to man tat ng, Song ji-hyo to ji-hyo Song. thx 125.160.241.178 (talk) 20:23, 25 December 2013 (UTC)

You'll have to ask them as to why they chose that method, but they did. Their submission guide says that Asian names can be submitted as Family-Name, Given-Name(s) like "Chow, Yun-Fat" but that will then be displayed as "Yun-Fat Chow". They don't record if it's an Asian name or a Western name, and it isn't always obvious -- SteveCrook (talk) 00:28, 26 December 2013 (UTC)

Is IMDB a reliable source for birth dates and death dates and appearances[edit]

  • Wikipedia:Identifying reliable sources says: "Questionable and self-published sources ... This includes any website whose content is largely user-generated, including the Internet Movie Database (IMDB),"

In various places in Wikipedia it says you cannot use IMDB because it is crowdsourced and not reliable. There is no evidence that dates of birth and death are crowdsourced, or not under editorial control of IMDB or that appearances are not reliable. On the contrary, IMDB was sued for displaying the real age of an actress and not what she submitted to the editors. "Hoang also made an issue of how IMDb had allegedly used credit information when she signed up to IMDb's Pro account and how IMDb's employees used a third party verification website to gain information to use in her profile." see this article The submission rules on the webpage for adding yourself as an actor say that "[biographical information] will be sent to the IMDb Data Editors for checking." You can submit a plot summary, you can rate a movie, you can leave comments, you can report an error for review. You can not go in an change Denzel Washington's birthday like you can in Wikipedia. Does that wording at Wikipedia:Identifying reliable sources need to be changed? --Richard Arthur Norton (1958- ) (talk) 18:37, 1 October 2014 (UTC)

"Film Rankings"[edit]

Its worth noting here that The Credibility Formula listed is almost certainly no longer used by IMDB. It was once posted by IMDB themselves as the equation that resulted in the IMDB "rating" or "weighted average". Around 2003, they removed any information about how their rating is calculated in an effort to avoid use of that information to "game" the system and skew one's film. At the same time, they mentioned that they are constantly adjusting their approach for calculating the IMDB rating based on other criteria, including giving greater weight to votes from members who fit certain criteria (perhaps "regular voters") and incorporating the median. One bit of evidence that this Formula is no longer in use is the data from the previous section: Jonas Brothers: The 3D Concert Experience is considered to be the worst film with a weighted average of 2.1 as of 2014, but has a rather ordinary arithmetic mean of 3.9. That information is correct, and the Formula listed could not generate that result. Unless anyone objects, I'll probably make some very minor edits to clarify that this was "once" the credibility formula used. Not a big deal, but its inaccurate for us to imply that it is still in use, when we can do basic math to demonstrate that its not.Deproduction (talk) 00:55, 6 February 2015 (UTC)

Some useful info from IMDB, indicating that we might want to delete this formula, as they make it clear they are no longer using it[1] The scheme combines a number of well-known and proven statistical methods, including a trimmed mean to reduce extreme influences and, most importantly a complex voter weighting system to make sure that the final rating is representative of the general voting population and not subject to over influence from individuals who are not regular participants in the poll. The scheme has been developed internally over the 10 years which the poll has been in operation and tuned on a regular basis to make sure it remains fair.

Most of the feedback we receive about our votes is based on the incorrect assumption that all votes cast by our users for a film have the same impact on the final rating. This is not the case. Different votes may have different weight when they're used to calculate the final weighted rating. Most people think of the arithmetic mean when they hear the word average. When calculating an arithmetic mean, all votes are treated equally: the average is the sum of all the votes divided by the number of votes.

A weighted average, however, is defined as "an average that takes into account the proportional relevance of each component, rather than treating each component equally". There's nothing arcane or mysterious about it: it's a very simple, universally accepted statistical method, commonly used in a wide variety of fields (from financial analysis to student reports).
