Aggregating document annotations

A system that comprises a plurality of components that are executable by a processor, the components comprising:

• a receiver component that receives a data packet from an application executing on a client-computing device by way of a network connection, wherein the data packet has a first format, and wherein the data packet comprises:
• an annotation that has been assigned to the document by an individual, wherein the annotation comprises a tuple, wherein the tuple comprises a first word or phrase, a second word or phrase, and a third word or phrase, and wherein the third word or phrase relates the first word or phrase with the second word or phrase;
• and
• relationship data that indicates that the annotation has been assigned to the document;
• and
• an aggregator component that places the data packet in a data repository with other data packets of the first format, wherein contents of the data repository are accessible to users by way of a network.

A computer-readable medium comprising instructions that, when executed by a processor, cause the processor to perform acts comprising:

• receiving, from a word processing application on a computing device, a data packet, wherein the data packet comprises:
• an annotation that corresponds to a portion of a document reviewed by a user of the word processing application, wherein the annotation comprises a tuple, wherein the tuple comprises a subject of a sentence or phrase, an object of the sentence or phrase, and a predicate that relates the subject and the object;
• and
• relationship data that comprises:
• first data that indicates that the annotation has been assigned to the document;
• second data indicates the portion of the document that corresponds to the annotation;
• third data that identifies an author of the document;
• and
• fourth data that identifies an author of the annotation;
• and
• repeating the act of receiving from a plurality of different computing devices, such that a plurality of data packets that comprise respective annotations and relationship data are received;
• causing the plurality of different data packets to be retained in a searchable database;
• receiving a query from another user;
• executing a search over the searchable database responsive to receiving the query from the another user;
• and
• outputting search results to the another user subsequent to executing the search over the searchable database, wherein the search results comprise an indication of relationships between documents, document authors, and annotation authors.
