What is the difference between 情報 and 知らせ


What is the difference between 情報 _jōhō_ and 知らせ _shirase_ ?

Both mean 'information', although I found more example sentences of 情報 as
'information' and of 知らせ as 'news'.

Finally, I would like to know which word to use to express:

  * "Paul will give you the **information** (i.e. the hour, the place, etc.) about the party of next Saturday"

  * "Your colleagues will give you all the **information** (i.e. the hour, the place, the tasks, etc.) about the next meeting with the boss".




**情報** is the word for "information" in general. In the given example
sentences, 情報 is the only word that can be used (another option is 詳細
"details").

**お知らせ** is more like "notification" or "announcement" (of an upcoming event).
You should remember this as a [lexicalized word that is almost always used
with お](https://japanese.stackexchange.com/a/86216/5010), even though some
dictionaries may not have a dedicated entry for this. (A few writers may drop
お in serious sentences, but it's rare.)

  * XYZデパート閉店のお知らせ  
XYZ Department Store Closure Notice

  * コンサートの最後に新曲リリースのお知らせがあった。  
At the end of the concert, there was an announcement of the release of a new
song.

**知らせ** (without お) is "news" or "report" of some important event that has
already happened. There are cases where "information" is a valid translation,
but it's far from the primary translation of this word. Besides, this is a
stilted word used mainly in formal greetings, essays and such. 知らせ also means
"sign; omen" in a few set phrases.

  * Aさんが危篤だという知らせを聞いて病院にかけつけました。  
I rushed to the hospital upon hearing the news that A was in critical
condition.

  * よい知らせをお待ち申し上げております。  
We look forward to hearing good news from you.

So パーティーの情報 refers to the information (the hour, the place, etc.) about the
party. パーティーのお知らせ refers to the announcement (or the invitation) itself.
パーティーの知らせ sounds like an odd expression to me (but if someone really said
this, it should refer to the same thing as パーティーのお知らせ). If you thought you
heard 知らせ "in daily life" in such a context, I suspect you have misheard
something or seen some weird misspelling.
