Natural Language Processing

A lot of information in a recipe is in the form of text. Therefore, Natural Language Processing is very important for us at Cookpad. For example, recipe search, recipe classification, and recipe summarization developed by Cookpad embody the information retrieval, document classification, and automatic summarization that are all applications of Natural Language Processing. To realize these, it is necessary to develop basic technologies of Natural Language Processing such as morphological analysis, named entity recognition, and synonymous expression recognition for the recipe domain. In this way, the R&D department studies Natural Language Processing from both basic and applied aspects, and supports the development of the company’s mission of “Make Everyday Cooking Fun”.
