Ontological how and why: action and objective of planned processes in the food domain (2023)
A closer examination of how we consider processes from a how (choice of mechanism), and why (choice of objective) perspective, and how the two get interwoven. A technical rice cooking example is included.

Food process ontology requirements (2022)
A paper reviewing OBO style process modelling in comparison to SOSA/SSN, OWL-Time, PROVO, and PO2 process related ontologies, culminating in a tentative recipe model that aims to satisfy representation of recipes in both a home and food science context.

The periodic table of fermented foods: limitations and opportunities (2022)
An overview of fermented foods from across the globe. “The periodic table of fermented foods aims to map this diversity on the 118 entries of the periodic table of chemical
elements. While the table fails to represent the diversity of fermented foods, it represents major fermentation substrates, product categories, fermentation processes and fermentation organisms.

How the environment shapes the microbiota in health and disease (2021). 
Carolina Tropini discusses principles governing the localization of intestinal bacteria and spatial relationships between bacteria and their hosts, including effects of change in extracellular concentration in the gut of solutes on bacteria cell pressure (osmotic perturbation), a common disturbance caused by food intolerance, malabsorption, and widespread laxative use. The presentation reveals many implications for personalized health and probiotics.

The landscape of nutri-informatics: a review of current resources and challenges for integrative nutrition research (2021)
The authors review the state of affairs in nutri-informatics data sharing, and “focus on the application of biomedical ontologies and their potential to improve the standardization and interoperability of nutrition terminologies and relationships between nutrition and other biomedical disciplines such as disease and phenomics.”

Perspective: Towards Automated Tracking of Content and Evidence Appraisal of Nutrition Research (2020)
The authors present a semiautomated approach to annotate, link, and track the content of nutrition research manuscripts. It involves the STROBE-nut ontology, crafted to describe and standardize the metadata components of research manuscripts, to manually annotate a sample of 15 articles and converted the semantic information into linked data in a Neo4j graph database through an automated process.

Using Word Embeddings to Learn a Better Food Ontology (2020)
A semi-supervised machine learning framework for the automated ontology population from an existing ontology scaffold by using word embeddings. Uses FoodOn structure and a corpus of Wikipedia documents as the training set.

Common Data Models and Semantic Interoperability Mechanisms (2020)
A report by the Demeter project on the European agri-food sector and pertinent IoT technology.

FOBI: an ontology to represent food intake data and associate it with metabolomic data (2020)
A novel ontology that describes food and its associated metabolite entities in a hierarchical way. This ontology uses a formal naming system, category definitions, properties and relations between both types of data.

Knowledge representation and data sharing to unlock crop variation for nutritional food security (2020)
To quote: “Here, we review generic efforts to standardize the description and management of crop trait data and discuss several issues currently constraining their exchange and comparison, with a focus on knowledge representation using ontologies, and their application to crop‐based dietary nutrition.”

Semantic Publication of Agricultural Scientific Literature Using Property Graphs (2020)
A pipeline for the generation of scientific literature knowledge graphs in the agriculture domain, consisting of paper RDF generation, including metadata and contents; semantic annotation of the content using AgroPortal; and property graph population by adding domain knowledge from ontologies. Tested on 127 agriculture articles.

FoodKG: A Semantics-Driven Knowledge Graph for Food Recommendation (2019)
A software toolkit that can be used to create a unified food knowledge graph that links various recipe and other food related information.

ISO-FOOD ontology: A formal representation of the knowledge within the domain of isotopes for food science (2019)
Focuses on the enumeration of certain stable isotopes and chemical elements within food (organic) compounds, in a new ISO-FOOD ontology.

The unmapped chemical complexity of our diet (2019)
A position paper exploring the impact and quantity of other chemical compounds besides the more well documented 150+ nutritional components tracked by common food composition databases.

FoodBase corpus: a new resource of annotated food entities (2019)
“A new annotated corpus of food entities, named FoodBase. It was constructed using recipes extracted from Allrecipes, which is currently the largest food-focused social network. The recipes were selected from five categories: ‘Appetizers and Snacks’, ‘Breakfast and Lunch’, ‘Dessert’, ‘Dinner’ and ‘Drinks’. Semantic tags used for annotating food entities were selected from the Hansard corpus.”

ONS: an ontology for a standardized description of interventions and observational studies in nutrition. (2019)
