Key phrases are used by the model to identify potential events in a piece of text. By looking for words like “invest” and “investment,” the model can identify the specific parts of a body of text that are most likely to contain investment events. Key phrases are generally verbs, but this is not a hard requirement - this tutorial includes the noun “investment” as a key phrase.
-
Includes all forms of the noun “investment” (investments, etc.).
-
Investment can be used as a descriptor for another noun, as in “investment portfolio” or “investment plan.” These cases likely do not indicate an investment event and therefore should not be annotated.
-
Includes all forms of the noun “invest” (invested, investing, etc.).
-
Investing can be used as a descriptor for another noun, as in “investing newsletter.” These cases likely do not indicate an investment event and therefore should not be annotated.
-
In the case of a compound tense, such as future tense, only annotate the main verb.
-
Roles are generally noun phrases.
-
If a proper name appears adjacent to a generic descriptor, just annotate the proper name.
-
Some roles are specified inside of prepositional phrases, e.g. “along the coast”, “from Whole Foods”, “to Tel Aviv”, Do not annotate the full span; just annotate the noun phrase.
-
Coordinated expressions that take a role should be annotated separately. This is also true if the coordinated expressions modify another expression that we include in the span.
-
In the case of a multi-word REX entity like “United States Department of Education” (organization), annotate the entire span.
-
Don’t annotate pronouns as entities. If a pronoun’s referent is available, annotate the referent instead.
-
Only include the head noun (without any adjectives, determiners, numbers/quantifiers, modifying prepositional phrases etc.) when annotating a role.
-
An exception to this is noun phrases where a modifier is central to the meaning of the phrase, as in “police department” or “graphics card.” In cases like these, the span should include both nouns.
-
Another exception is nationality descriptors like “German tanks”. Include the adjective in the span in these cases.
-
Another exception is numeric/currency entities like “4% per week” and “$10 a share”. Annotate these whole spans.
-
The money role applies to an amount of currency allocated during an investment.
-
When annotating a money entity, be sure to include the following:
-
Units such as “billion dollars”.
-
Symbols that indicate currency type, such as “$”.
-
Tickers such as "USD 1.5 B" and "161,500 BTC".
-
Slang such as "bucks:.
-
The investor role applies to a person or organization that invests an amount of money in another organization.
-
The investor does not always come before the asset. Sentences may be structured so that the investor is the object of a preposition. For example:
-
The asset role applies to an organization that a person or organization is investing money in.
-
For the purposes of this tutorial, only annotate assets that are organizations. A more extensive project might also include entities like products.
