A Structure-Based Clustering on LDAP Directory Information

  • Conference paper

Part of the book series: Lecture Notes in Computer Science ((LNAI,volume 4994))

Abstract

LDAP directories have rapidly emerged as the essential framework for storing a wide range of heterogeneous information under various applications and services. Increasing amounts of information are being stored in LDAP directories imposing the need for efficient data organization and retrieval. In this paper, we propose the LPAIR & LMERGE (LP-LM) hierarchical agglomerative clustering algorithm for improving LDAP data organization. LP-LM merges a pair of clusters at each step, considering the LD-vectors, which represent the entries’ structure. The clustering-based LDAP data organization enhances LDAP server’s response times, under a specific query framework.
