Description

This disclosure relates to a technology that assists in modifying software design documents. Software design specifications are described in multiple interrelated design documents. Even after a design document is created, it undergoes various revisions due to corrections of errors, bug fixes, specification changes, and so on. A single revision may require revisions to multiple design documents, making the process cumbersome. Therefore, technologies to support the revision of design documents have been proposed (see Patent Document 1). The method described in Patent Document 1 involves calculating the similarity of words from a glossary and design information, while considering the connections between design documents during the design process. This allows the designer to receive highly accurate correction information regarding errors in the design documents.

Embodiments of the present invention will be described below with reference to the drawings. <System Overview> The design document revision support system according to this embodiment is a computer system that assists in the revision of various design documents created in system development projects. This system makes it possible to prevent human errors in design document revisions and ensure the consistency of the revisions. First, the design document revision support system analyzes the content and formatting of the input design document and converts it into structured text. Specifically, the design document revision support system converts the design document into structured text using Markdown notation. Markdown notation allows for the representation of document structure using simple notations such as headings, bullet points, and tables. If the design document is created in Excel, the design document revision support system converts the Excel table into a Markdown table format. In doing so, the system extracts text data while preserving formatting information within cells, and analyzes the table structure (merged cells, borders, etc.) to generate appropriate structured text. The design document revision support system can also, as an example, convert design documents using generative artificial intelligence. Generative AI is a Large Language Model (LLM), which understands the context and formatting of the document and generates appropriate structured text. Furthermore, the design document revision support system generates a graph from structured text. The graph is a diagram that represents a network, where meaningful strings of text are treated as nodes, and nodes are connected by edges according to their relationships. Specifically, the design document revision support system first extracts each unit of text within the structured text as a node. For example, the strings written in the cells of a table using Markdown are treated as unit text. In the case of Excel, the content of each cell is treated as a single node. Cells contain information expressed in words such as noun phrases, as well as information written in natural language. On the graph, all of this information is treated as nodes. Furthermore, the design document revision support system analyzes the relationships between the unit texts and connects them, i.e., the nodes, with edges according to these relationships. At this time, the edges reflect the hierarchical relationships based on the document structure and the semantic relationships of the content. Each edge may also be assigned attributes according to the relationships between the unit texts. Furthermore, the design document revision support system receives instructions regarding the revision locations and content, and then modifies the locations in the graph acc
