A method for extracting major workflow composed of ingredients, tools, and actions from cooking procedural text

要旨

In this paper, we propose a method for extracting a major workflow of cooking procedure from a Japanese recipe on the Web. It is utilized for various applications including recipe search, summarization, and visualization. This major workflow is represented as a tree in which each leaf corresponds to a food or a cooking tool, each intermediate node corresponds to a cooking action, and the root node corresponds to the final cooking action. We had already developed a method for converting a procedural text to a workflow as a directed acyclic graph, and the proposed method is based on the previous one. The results are evaluated by comparing with manually extracted major workflows as a ground truth.
