Abstract: A method of determining an operational difficulty of a process described in a document including text includes generating text data corresponding to the text of the document, and generating a word vector output by processing the text data through a plurality of word vectors, the plurality of word vectors based on a domain-specific text collection and a general-language text collection. The method further includes generating a statistical information output by processing the text data through a plurality of statistical information vectors, the plurality of statistical information vectors based on the domain-specific text collection and the general-language text collection, and generating a gated recurring unit (GRU) output by processing (i) the word vector output, (ii) the statistical information output, (iii) word-level data based on the text data, (iv) sentence-level data based on the text data, and (v) paragraph-level data based on the text data through at least one GRU.
