What is the difference between Tag and Category?

Consider the example of Steam, where in addition to tags to the games, there are categories and genres.

What is the difference for example :
"Free"is a category, tag or genre?
A "Shooter"is a category, tag or genre?
If you take the OS, it can also be TagEntity or solely for this purpose PlatformEntity.

How to find this line?

Genre/Direction - always a fixed list.
Category - explicit grouping by key characteristics (many do not intersect each other).
Tag - the implicit grouping free sets of signs (many overlap).

Competing sites:
1. Structure ("tree") of categories varies most of the names of the genres, categories, and tags.
2. Slightly different sets of different tags and their total number.

Hint: a good set of tags = a good Recommender system
Somehow it's blurry.

Than a "shooter" not a genre, category and tag at the same time?
Or "Comedy" may in fact be a tag and at the same time, category, genre of movie, depending on the context

There is a movie, let "Mr.Bin", the genre (Comedy + kids), category - Comedy or kids?, tags (Comedy + kids) out nonsense.
Because there is another film, let the "John Wick", the genre (Western, Thriller), category and action tags ( action, shooter, tragedy)

+- sketched, not watching what they mark, different on different sites. - velda.Maggio85 commented on April 4th 20 at 00:59
@velda.Maggio85that on Russian/literature in the school put?!))

1. What are the difference between the words "explicit" and "implicit".
2. What is the order of the priority marking from all three agencies?
3. What is the lowest priority and in what cases? - sydnie commented on April 4th 20 at 01:02
Russian and its literature was not Ukrainian. Perhaps so, Pushkin was held in the class 6-Ohm, 10 years +-ago. Use extensions that highlight when the error in the word.
1. exact and inexact, vague.
2. Marking order? I think you mean priorities? Tag 3, genre 1, cat-ia 2.
3. This is the lowest tag. I pondered the words of others, and came to the conclusion that the category "it" that does not intersect with other. For example Buns and SSD can't be tagged, because then you can stick to the product, bun + ssd. Though again, if this is some bakery that bakes custom bakery products. It is quite likely. So everything is still vague and depends on me as from business, industry.

STI was pretty terrible example. Because people there do not understand what you are doing. So it looks from the outside. - velda.Maggio85 commented on April 4th 20 at 01:05
@velda.Maggio85, Almost all the way, but there are inaccuracies:
1. You brought just the synonyms of the words, not the differences.
The differences in the intersection of the sets (clear - do not overlap non - overlap).
2. All true.
3. Grouping by similar, less significant signs.
A set of tags gives the maximum accuracy of the compilation of proposals by crossing a larger number of less important characteristics.

Example: laptop
Genre/direction: IT
Category: laptops
Tags: game, up to 2kg. - sydnie commented on April 4th 20 at 01:08

Initially, face not is a question of classification of the objects. You can only have categories and stuff in there.
But would be for the user to choose between: blue, tall, round and sweet? Where to allocate the object, if it is round and sweet? To avoid such confusion, are genres, categories, tags, categories, filters, and so on. How exactly between them is the line depends on who designs the structure.
For example:
The nature of the game and what the player will do within it we call Genre. The genre is to describe what the game can do. A branch of the genre, this is kind of category in which the objects are separated. The category called Genre.
Category can be called leading the game's plot. In category a and additional features, but then, to avoid confusion, it is necessary to design sub-categories.
The tags will include clarifying details and descriptions that are left.

The basic structure is, then you need tests to find out whether it is convenient for users to operate such system or changes are needed. What they expect to see in the same category, and for them unfamiliar. Once the data is collected, analyse them and finalize the structure.

Something like that. From your example, Free I can not attributed to the genre. No such action or activity as "free". Tag or category. Intuitively, I would be more related to Tags.
Shooter go and shoot, it's definitely the Genre, but it could be a Category, if so intended in the project. In General, the genre is a subcategory

Clear edge as a 3 m high reinforced concrete fence with barbed wire - no.

The point is that we classify objects by separating them according to some common characteristics. For example, the material from which they are crafted, color, taste, odor, method of application. It is also important to check, to test how comfortable others use an existing structure and modify it if necessary.

I hope that clarified a little the issue.
Then why not call all the tags? They are the same notes? - velda.Maggio85 commented on April 4th 20 at 01:01
@velda.Maggio85, why not? Do if so convenient for your customers. This is the only criterion, I think.
On the example of games, whether it is convenient to choose a game from this list, not as a broken or visually?
About space
For boys

Me, not so much. - Billie84 commented on April 4th 20 at 01:04
@velda.Maggio85, Let's have a whole set of objects. One private category item takes away from that whole certain part. The more items overall, and the more heterogeneous, the more categories you want this whole look for private. Moreover, categories can be unrelated.
Sometimes it is convenient to write only the tags the user notes you need a list of all the objects is filtered and only the necessary.
Sometimes it is better to create several large categories with sub-categories, calling them tags, genres, year of release and anything.
When and how to group the issue of convenience for the user and the objectives of the project.

P. S. I've been writing and realize that I'm not sure my answer helps you or confuses you. Maybe I do not about writing what you want to understand? You with some specific purpose are interested in? Do you need something? - Billie84 commented on April 4th 20 at 01:07
@Billie84, No, nothing to do I do not need. I have always found filtering by tags more convenient than with the categories and sub-sub-sub... nested and tags. Pondering over their difference for a long time, maybe even asked a similar question here a few years ago.
Much easier to write optimizing selection, the selection of recommendations than to sculpt a bunch of categories. Which in turn always made me confused. Why?

Here's a page with filters https://store.steampowered.com/search/?filter=tops...
Unlike home where "free" is a genre of game, then there is the category "Game" and "Program", and that's where the difference is? Or "the Game" and "Demo"?

Did not seem to overlap categories according to your words.
In the case of "the Game" and "Soundtrack" or "the Game" and "DLS" everything is clear.

There is already a genre as a tag, because you can select multiple at once and mingled with tags. And what if we say we want to choose the game is a casual shooter, we choose the category "Game" + "tag Shooter, he's a genre" + "Casual tag, aka ANR". In fact all the same that to choose the 3 tag. - velda.Maggio85 commented on April 4th 20 at 01:10
@velda.Maggio85, but you do not understand what guided, when put like different types in the same bundle? Like this?

Just grouped the semantic core of the site. Apparently, in the gathering phase or the subsequent testing, it was found that most users share games and programs. In fact, Games are Programs. But if the majority has a belief like: game is fun, and the program is a tool (or something), it makes sense to make the separation.
Free, Early access, Demos - these can be categories that are important to users.

Even search by genre, top Racing and Indie. Second this is not a genre, as far as I understand. But it is necessary in the genres of, because as a consumer the majority thinks and it is so convenient.
But the fact that the consumer is so convenient, I decided whoever designed these filters. When the case is serious, the logical division is only a sketch of the future layout. The main criterion is user acceptance testing.
One of the options: take the sample of subjects, people, potential customers, hand out word cards and ask these words to sort out groups (by similarity). After collect, analyze, and work is almost ready category, familiar to future users. Part categories ready.
Some tests are not as explicitly, but more hidden. You can read ready or not ready users to see some things around.

Sometimes tests are not carried out, the designer is guided by its own logic/common sense/experience of their ancestors and something else. It is not very efficient, but sometimes testing there is no budget, and a competitor is all grouped and so would like to cut corners.

There are basic laws of perception, they too should be considered. And then there are business goals.

Good categorization it is always working with intentions, desires and habits of people.

Free at the top may reflect the fact that the search often type "free to play, free download and so on". Perhaps most are not willing to pay for games in principle. Or not willing to buy a pig in a poke - an unfamiliar toy. It does not matter. But this query is for free, and apparently "free" is a very important criterion for the site or theme. Another will be different. - Billie84 commented on April 4th 20 at 01:13
@velda.Maggio85, "free" is not a genre, a category, kraynyak tag - dwight.Tillman commented on April 4th 20 at 01:16
@dwight.Tillman, it's a genre he's a tag :) - velda.Maggio85 commented on April 4th 20 at 01:19
@Billie84, in the end, we come to the conclusion that a clear structure are not all in the situation and the question can be closed, very much painted, thank you! - velda.Maggio85 commented on April 4th 20 at 01:22

There is a basis - genre, their number is limited and rarely replenished. Next is the convenient division into categories, for example, zombie games, games about space, etc., and then tags - tertiary element that helps to track interesting topics, crossing several genres and categories, such as company name or main theme, for example, EA, Valve, survival, build a city, etc.
Category with the same success can be to different genres, hence the meaning is the same as the tag. And since the genres are similar to the tags, as for me and makes no sense.
Again, no clear boundaries, everything is conditional.
I would like to know her or to determine for themselves. - velda.Maggio85 commented on April 4th 20 at 01:03
@velda.Maggio85, of course, nothing prevents you to mix all of this as anyone, confusing the end user more, but there are certain rules and conventions that should/could follow. - dwight.Tillman commented on April 4th 20 at 01:06
@dwight.Tillmanwas possible in the Studio please? What you said sounds more like an opinion, not a rule. - velda.Maggio85 commented on April 4th 20 at 01:09
@velda.Maggio85, the view that there is a list of certain genres that are standard for several years? You can Google and find a Wikipedia article. - dwight.Tillman commented on April 4th 20 at 01:12
@velda.Maggio85, or you the long experience of humanity to one place? - dwight.Tillman commented on April 4th 20 at 01:18
@dwight.Tillman, when people draw conclusions based on previous experiences of all generations in the tens of thousands of years, that fly "nevazmojna" and what is the result?
I saw these links but if you look at real projects, there are mixed. Whether the developers hodgepodge mixed, whether moderators and content writer. Apparently such neponyatki many people.

I considered the Outlet store and Steam as examples. - velda.Maggio85 commented on April 4th 20 at 01:21
@velda.Maggio85, in short, do what you want, only then do not complain - dwight.Tillman commented on April 4th 20 at 01:24
