    abstract = "Entities are pivotal in describing events and objects, and also very important in Document Summarization. In general only explicit entities which can be extracted by a Named Entity Recognizer are used in real applications. However, implicit entities hidden behind the phrases or words, e.g. entity referred by the phrase “cross border”, are proved to be helpful in Document Summarization. In our experiment, we extract the implicit entities from the web resources."
