    Abstract
    Presents a survey and discussion on signature-based text retrieval methods. It describes the main idea behind the signature approach and its advantages over other text retrieval methods, it provides a classification of the signature methods that have appeared in the literature, it describes the main representatives of each class, together with the relative advantages and drawbacks, and it gives a list of applications as well as commercial or university prototypes that use the signature approach

    Abstract
    Hypertext systems provide an appealing mechanism for informally browsing databases by traversing selectable links. However, in many fact finding situations string searching is an effective complement to browsing. Describes the application of the signature file method to achieve rapid and convenient strung search in small personal computer hypertext environments. The method has been implemented to a prototype, as well as in a commercial product. Presents performance data for search times and storage space from a commercial hypertext database and discusses user interface issues. Experience with the string search interface indicates that it was used successfully by novice users
