think of retrieval effectiveness in terms of precision and recall
...Bibliographic remarks The best introduction to information retrieval is probably got by reading some of the early papers in the field
...One early publication worth reading which is rather hard to come by is the report on the Cranfield II project by Cleverdon et al
...Papers on information retrieval have a tendency to get published in journals on computer science and library science

influence the choice of [classification]method and the results obtained
...There are two main areas of application of classification methods in IR:1 keyword clustering;2 document clustering
...The first area is very well dealt with in a recent book by Sparck Jones [5]...Good [6]:We define the organisation as the grouping together of items e

The structure of the book The introduction presents some basic background material,demarcates the subject and discusses loosely some of the problems in IR
...The two major chapters are those dealing with automatic classification and evaluation
...Outline Chapter 2:Automatic Text Analysis contains a straightforward discussion of how the text of a document is represented inside a computer
...Chapter 3:Automatic Classification looks at automatic classification methods in general and then takes a deeper look at the use of these methods in information retrieval
...Chapter 4:File Structures here we try and discuss file structures from the point of view of someone primarily interested in information retrieval
...Chapter 5:Search Strategies gives an account of some search strategies when applied to document collections structured in different ways
...Chapter 6:Probabilistic Retrieval describes a formal model for enhancing retrieval effectiveness by using sample information about the |

Sparck Jones has carried on this work using measures of association between keywords based on their frequency of co occurrence that is,the frequency with which any two keywords occur together in the same document
...The term information structure for want of better words covers specifically a logical organisation of information,such as document representatives,for the purpose of information retrieval
...The organisation of these files is produced by an automatic classification method
...Evaluation of retrieval systems has proved extremely difficult

documents can be stored as closely together as possible
...Finally,the reader may be interested in pursuing the use of cluster methods in pattern recognition since some of the ideas developed there are applicable to IR
