Systems, methods, software and interfaces for entity extraction and resolution and tagging

摘要

For automated text processing, the inventors devised, among other things, an exemplary system that includes an entity tagger, an entity resolver, a text segment classifier, and a relationship extractor. The entity tagger receives an input text segment, and tags named entities with the segment as being a person, company, or place. The entity resolver accesses authority files, and associates the persons and companies named in the text segment with specific entries in the files. The text segment classifier determines whether the text segment includes a relationship event, such as job-change event or merger and acquisition event, and if an event is detected, the relationship extractor determines the event role of entities named in the segment. For example, the extractor determines for a merger and acquisition event, which named company was the acquirer and which was acquired.

1. A computer-implemented method comprising:
accessing a preexisting entity list;
analyzing by a computer a first document to detect an entity, the entity comprising a person, place, or organization, the first document being associated with a current legal event;resolving the entity with the preexisting entity list and:upon determining by the computer the entity is not present in the preexisting entity list, adding the entity to the preexisting entity list and generating a first set of relationship data associated with the relationship between the first document, the current legal event, and the entity, the first set of relationship data further comprising a set of information associated with the relationship between the entity and the current legal event; orupon determining by the computer the entity is present in the preexisting entity list, generating a first set of relationship data associated with a relationship between the first document and the entity, the first set of relationship data further comprising a set of information associated with the relationship between the entity and the current legal event;repeating the resolving step for each distinct entity detected in the first document;generating a second set of relationship data representing the relationship between the entity and a professional support resource comprising tools for creating and editing a work product document, the work product document comprising a reference to at least one of the resolved entities;storing the first and second sets of relationship data in a memory associated with the computer;displaying a user interface to allow a user to select from a set of professional support resources;associating the reference to the at least one resolved entity with a smart tag; andediting the work product document in response to a signal representing a user input associated with the professional support resource and related to the smart tag.
