Abstract:
To provide information for preventing or solving problems concerning a product related to a chemical substance.SOLUTION: A data collection unit acquires a plurality of documents including a sentence input in a manufacturing process of a product relative to each of the products related to a chemical substance. A first learning unit performs machine learning based on a word in a document, and when generating a first learned model for evaluating similarity of words or sentences, a second learning unit performs machine learning based on the word in the document to generate a second learned model for evaluating importance of the word in the document. A third learning unit cuts out a character string in a document in a specific unit to generate a third learned model for evaluating a match with the character string. A retrieving unit retrieves a document associated with a retrieving character string based on the first learned model, the second learned model, and the third learned model. A retrieving input/output unit outputs at least a part of information of the document retrieved by the retrieving unit based on product identification information.SELECTED DRAWING: Figure 3
