You have studied that entites have associations such as “a hotel has a price” , “a hotel has a rating”, “ginger is a plant” etc. Let’s study some common types of association.
Aboutness
When machines are analysing text, we not only want to know the type of semantic association ‘is a’ and ‘is in’ but also want to know what is the word or sentences about. Take, for example, the example that we took at the start of the session
‘Croatia fought hard before succumbing to France’s deadly attack; lost the finals 2 goals to4’
In the above text, if we want the machine to detect the game of football ( it could be about other sports such as hockey as well , but let’s keep thing’s simple and assume it ‘s about football ), then we need formally define the notion of aboutness.
We can, for example , detect that the game of football by defining semantic association such as “Croatia ” is-a “country”, “France” is -a “country”, “finals” is -a “tournament stage” , ” goals ” is -a “scoring parameter” and so on.
