The Double-KWIC Coordinate Indexing Technique: Theory, Design, and Implementation.
Lay, William Michael
The development of an automatic indexing technique, called Double KWIC (DKWIC) Coordinate Indexing, is described which extends the KWIC indexing principles to provide easy access to an additional level of specificity for information indexed under these frequently appearing terms. Chapter 2 discusses indexing terminology and some fundamental relationships between indexing and document retrieval. Chapter 3 sketches a brief history of automated indexes describing frequently encountered methods of construction and display. Chapter 4 introduces the Double-KWIC Coordinate Indexing scheme and discusses its advantages and disadvantages relative to several other KWIC indexing schemes. Chapter 5 discusses refinements in the prototype indexing scheme which led to the production of KWOC-DKWIC hybrid indexes. Chapter 6 considers the problems of vocabulary control in a natural language environment. Several methods of automated vocabulary normalization are described. Chapter 7 examines the role played by the index analyst in creating a Double-KWIC Coordinate Index and resolves the plaguing problem of main term selection by an automatic selection algorithm which can only be applied successfully with KWIC-DKWIC hybrid indexes. The final chapter examines the parametric controls of the KWIC-DKWIC indexing scheme and discusses some relationships among these parameters and the indexes produced. (Author/NH)
