Machine indexer is referred to as a kind of indexing
system in which keywords are extracted from the title or body of a
text and organized in the index entries using computer algorithm.
Althogh there is an increasing need for applying computer in indexing
machine indexer has not been developed for Persian language yet.
Therefore in this paper the results of investigating and identifying of
theoretical and practical aspects of such system in the Iranian
Research Institute for Information Science and Technology are
presented. To do so, firstly the relationship between indexing and
information retrieval, theoretical debates and the machine indexing
revolution, the practical and procedural viewpoints of machine
indexing, successful projects in different countries and for different
languages, and the requirements of machine indexer for Persian
language are discussed. Then the elements of a machine indexer for
Persian language are defined and its conceptual model and also the
relationships between the elements, the details of subsystems, and the
indexer logical system are designed. Finally, the requirments of
developing the system for the Iranian Research Institute for Information Science and Technology are discussed and the state of the art of the
implemented projects and existing experiences in this regard are defined.
