标签系统中的关键字或关键短语?
在有效地对网络内容进行分类方面,我想知道关键字(又名标签,例如google-app-engine)和关键短语(例如google app engine)之间的优缺点是什么。
我知道 delicious.com 和这个网站< /a> 使用关键字作为标签。但他们为什么不使用关键词呢?如果他们使用关键字,那么可能会导致某些不一致(例如,app-engine 和 appengine、web-2.0 和 web2.0)。我想如果我选择使用关键词作为标签,那么它会变得更好。我不知道为什么这两个主要网站不像我想象的那样工作。使用关键词有什么缺点吗?请指出给我看。
In term of effectively categorizing web content, I am wondering what are the pros and cons between keyword (a.k.a tag, e.g, google-app-engine) and keyphrase (e.g. google app engine).
I know that delicious.com and this site are using keyword as a tag. But why don't they use keyphrase instead? If they use keyword, then it may cause certain inconsistences (e.g., app-engine and appengine, web-2.0 and web2.0). I wonder if I choose using keyphrase as a tag, then it will become much better. I have no clue why those two major sites don't work as the way I thought. Are there any cons of using keyphrase? Please point it out to me.

明显的区别:
如果您使用
keywords-like-this
,则多个关键字列表可以用空格分隔。如果您允许
像这样的关键字短语
中包含空格,则您无法使用空格分隔关键字短语。这意味着您要么引入用户需要了解的其他分隔符,要么拥有更复杂的用户界面来编辑标签。
(您提到的不一致问题将以任何一种方式发生:
appengine
/appengine
与app-engine
/appengine
.)The obvious difference:
If you use
keywords-like-this
, then a list of multiple keywords can be space-separated.If you allow
keyphrases like this
with spaces in, you can't space-separate the keyphrases.That means you either introduce some other separator character that your users need to learn about, or you have a much more complex user interface for editing tags.
(The inconsistency problem you mention will happen either way:
app engine
/appengine
vs.app-engine
/appengine
.)
