GRAMMAR
〜ものと思う
think that
believe that
Explanation
NOTE

〜ものと思う means to think that or to believe that — it states an assumption you hold to be true.

会議かいぎ中止ちゅうしになったものとおも
I believe that the meeting was cancelled.
NOTE

It is formal and sounds firmer than a plain 〜と思う, expressing a confident, settled judgment.

みな賛成さんせいしているものとおも
I think that everyone is in agreement.
The clause before ものと describes the situation you assume to be the case.
NOTE

Attach ものと思う to a verb in plain form, the form that states the situation you assume.
