The invention provides systems, methods, and computer programs to improve the accuracy and efficiency with which data analysts can use news stories, press releases, and other sources of information to maintain databases that contain information about individuals and businesses and other organizations. Documents containing material information are acquired in computer-readable form and optionally may then be reduced to raw text. One or more computerized systems process the text and tag important terms such as proper nouns, job titles, awards, and other terms indicating professional, educational, corporate, or other developments. The invention provides a user interface with which a data analyst can review, confirm, remove, modify, introduce, and link the tags, ultimately adding the information and links to a database and storing the source document in an electronic warehouse for future retrieval.
