An assistance device (10) includes a generation device (100) and an analysis device (200). The generation device (100) executes (a-1) to (a-5), with i being equal to 1 to n, and generates multiple pieces of process information. The generation device (100) extracts a plurality of material words from a document i in (a-1), extracts a treatment word i from the document i in (a-2), extracts a synthesis condition i, which is a condition i of a treatment i, from the document i in (a-3), extracts a characteristic value i pertaining to an objective material from the document i in (a-4), and generates process information i by correlating the plurality of material words, the treatment word i, the synthesis condition i, and the characteristic value i in (a-5). An analysis device (200) comprises a compounding unit (204) that generates compounding process information including a portion shared among the multiple pieces of process information and a plurality of different portions, and an output unit (205) that outputs the multiple pieces of process information.
