Queries are received and multiple discussion groups that are relevant to the query are determined based on the messages that are associated with the discussion groups and the topic identifiers associated with the discussion groups. The relevant discussion groups are ranked using a group preference model that simulates the behavior of a hypothetical seeker that considers discussion groups by selecting a message author who is an authority in a particular group, and exploring the discussion groups that are preferred by the selected author. The behavior of the seeker is simulated using a stationary Markov process and is used to generate a probability distribution that is used to rank the relevant discussion groups. The ranked relevant discussion groups are provided in response to the query."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ranking relevant discussion groups","description":"Messages are collected and processed to determine topic identifiers that correspond to discussion groups.
