Abstract
Methods and systems for detecting expiration time of an article include receiving the article for a pre-planned event. The article is analyzed to identify one or more attributes. The article is matched to an event identifier using the article attributes. The event identifier is pre-defined and stored in an event database. The event identifier acts as an index to the event database for obtaining event characteristics of the pre-planned event. The article attributes are examined to identify event phase indicators that correlate to a specific event phase of the pre-planned event. The expiration time of the article is computed based on the specific event phase identified for the pre-planned event. The expiration time is used to rank the article and for considering assigning the article to a content pool of articles that is selected for publishing for the specific event phase of the pre-planned event.
