The present invention provides an information query method and apparatus. The method includes : obtaining a query word input by a user through a terminal, identifying a target entity in the query word and determining a globally unique identifier (GUID) of the target entity for a knowledge map; determining a target entity type corresponding to the target entity according to a corresponding relationship between an entity and the entity type. The target entity type is used to indicate the target attribute and/or target entity relationship to be queried of the target entity; according to the GUID and an identifier of the target attribute and/or an identifier of the target entity relationship, querying an attribute value and/or a related entity corresponding to the identity of the target attribute and/or an identifier of the target entity relationship in the knowledge map; returning a search result to the terminal, so that the terminal displays the attribute value and/or related entity corresponding to the target entity to the user in the form of an entity detail card. The embodiments make the content corresponding to the search result have a clear structure, comprehensive and accurate.
