New Entity Query Functionality

Mathematica 12: New Entity Query Functionality

Entities are references to isotopes, food, libraries, stars and hundreds of other types of things in the world. With entities, you can retrieve data like the length and an image of a zebra; implicit entity classes allow querying for entities using constraints on property values. Entity stores allow you to register your own entities. Version 12 of the Wolfram Language extends the capabilities of the entity framework by adding support for "on the fly" properties, filtering and sorting entities by general conditions, aggregation, combining types and sampling of entity classes.

Astronomy & Space Science Entities

Mathematica 12: Astronomy & Space Science Entities

In Version 12, the breadth of coverage for curated data in astronomy and space science has grown significantly. These areas are now covered by many entity domains, such as observatories, satellites, space probes, planetary science, astrogeology, stellar science and galactic science. This large amount of data, combined with additional functionality to work with dates and locations, opens the door to knowledge‐based computing on astronomical scales.

Biology & Medical Entities

Mathematica 12: Biology & Medical Entities

Version 12 has a rich collection of computable knowledge in biology and medicine. The data collections cover diverse areas, ranging from human and animal anatomy to species taxonomy to genes, mutations and diseases. Using the built-in Wolfram Language functions, key characteristics of biological systems, including the structural and functional organizations of living organisms, can be analyzed and visualized.

Math Entities

Mathematica 12: Math Entities

The Wolfram Knowledgebase contains extensive data in a wide variety of knowledge domains. Curated mathematical data, first introduced in the Wolfram Language in Version 6, is an active area of development that continues to grow both in scope and coverage. As of Version 12, more than 20 mathematical domains are covered, including curves, laminae, solids, surfaces, knots, graphs, finite groups, function spaces, lattices and more. Precomputed values for a comprehensive set of properties are available for each mathematical entity.

Geographic Entities

Mathematica 12: Geographic Entities

Version 12 provides expanded and enhanced coverage of dozens of built-in geographic entity types, from natural features like seas and mountains to manmade structures like bridges and stadiums. Entities work seamlessly with geographic visualization functions to generate custom maps showing the location or density of various features. Alignment between different entity types allows for programmatic exploration of connections between structures, geographic features, people and more, and curated data about physical and historical aspects of thousands of entities is regularly updated and expanded.

Food and Nutrition Entities

Mathematica 12: Food and Nutrition Entities

The food and nutrition data available in the Wolfram Language seamlessly integrates detailed information for tens of thousands of foods and many nutrients into the Wolfram Knowledgebase. With thousands of computable packaged food ingredient entities, powerful queries can be formed to search through more than tens of thousands of packaged foods. Additionally, curated physical data such as colors, shapes, dimensions and serving sizes is available for hundreds of food types, allowing for unlimited knowledge-based programming, data analysis and exploration.
