Abstract: A method for semantic-based information input that includes receiving a user input from a user. The method also includes querying a database using the user input as a keyword, wherein the database includes objects, wherein each object includes a name and at least one attribute and ones of the objects include respective pointers to others of the objects indicating types of relationships therebetween. The method further includes receiving a query result, wherein the query result includes at least one matching object for which the keyword matches the at least one object's name or at least one attribute and at least one object with which the at least one matching object has a relationship indicated by the at least one matching object's pointer and presenting the query result to the user.
