a phrase
Without knowing the content of the lecture, she did not attend the meeting.
"Since she knew what the lecture was about" in the first sentence is replaced by the participle phrase "Knowing what the lecture was about" in the second sentence."Knowing" is the present participle of the verb "to know". Here it works like an adjective describing "she". She was a "knowing" woman. She was a "knowing-what-the-lecture-was-about" kind of woman.
