Determining and maintaining a list of news stories from news feeds most relevant to a topic

A system, comprising:

• a memory;
• a server, coupled to the memory, the server to:
• obtain a first list of stories pertaining to a topic belonging to a set of first news feeds;
• compute an initial story score for each story in the first list of stories from a set of key terms scores, wherein each key term score is based on the number of times that the key term appears in a second list of stories pertaining to the topic belonging to a set of second news feeds;
• and
• output a set of top stories from the first list of stories based on a tradeoff between the amount of overlap in key terms among the stories in the first list of stories and key terms among the stories in the second list of stories in view of the initial story scores of the stories in the second list of stories,
• wherein a first story from the first list of stories is included in the set of top stories when the degree of overlap between the key terms in the first story and the key terms in a second story is above a threshold, and
• wherein the first story is outputted based on the similarity of the first story to the second story against which the first story is measured.

A non-transitory computer readable storage medium including instructions that, when executed by a server, cause the server to:

• obtain, by the server, a first list of stories pertaining to a topic belonging to a set of first news feeds;
• computer, by the server, an initial story score for each story in the first list of stories from a set of key terms scores, wherein each key term score is based on the number of times that the key term appears in a second list of stories pertaining to the topic belonging to a set of second news feeds;
• and
• output, by the server, a set of top stories from the first list of stories based on a tradeoff between the amount of overlap in key terms among the stories in the first list of stories and key terms among the stories in the second list of stories in view of the initial story scores of the stories in the second list of stories,
• wherein a first story from the first list of stories is included in the set of top stories when the degree of overlap between the key terms in the first story and the key terms in a second story is above a threshold, and
• wherein the first story is outputted based on the similarity of the first story to the second story against which the first story is measured.
