Project auxiliary support system and method based on artificial intelligence

The invention relates to a project auxiliary support system based on artificial intelligence and a method thereof. The method comprises the following steps: carrying out one-hot coding on an obtained first item feature type; semantic coding based on sentence granularity is carried out on the obtained item text description segment; calculating a topic-content semantic association degree between the sequence of the semantic coding vectors of the item text description sentences and the one-hot coding vectors of the first item feature type; then, after the subject-content semantic association degree sequence is subjected to normalization processing, the normalized subject-content semantic association degree sequence is used as a weighted weight to perform important content enhancement optimization so as to obtain an optimized item text description sentence semantic coding vector sequence; then, the text is processed through a project feature generator based on a decoder to obtain a project feature text descriptio
