Read the following sentence for once: "Using a knowledge poor approach (explicit information from the text rather than implicit world knowledge)the study investigates to what extent syntactic and semantic constraints can be used to resolve anaphora. Since there has an article in "Using a knowledge.....",it is sure that there has a noun. But I am confused to identify noun and adjective from this three words (knowledge poor approach ). Will you explain me which and how one is acting as a noun another is adjective? What has been meant by "knowledge poor"/"poor approach"?
