WebDocument clustering has been investigated for use in a number of different areas of text mining and information retrieval. Initially, document clustering was investigated for improving the precision or recall in information retrieval systems [Rij79, Kow97] and as an efficient way of finding the nearest neighbors of a document [BL85]. WebClustering is used in information retrieval systems to enhance the efficiency and effectiveness of the retrieval process. Clustering is achieved by partitioning the documents in a collection into classes such that documents that are associated with each other are assigned to the same cluster. This a …
WebCluster hypothesis. In machine learning and information retrieval, the cluster hypothesis is an assumption about the nature of the data handled in those fields, which takes various forms. In information retrieval, it states that documents that are clustered together "behave similarly with respect to relevance to information needs". [1] WebNov 1, 2024 · All retrieval systems were evaluated using that metric and the selection was based on that metric value. The limitation of that method is it only considers performance, while it ignores diversity in those component systems. Therefore, there is room for improvement. In this paper, we propose a clustering-based approach.

However, clustering is an ill-defined problem in the sense that the data partitions output by clustering algorithms have no guarantee to satisfy end users’ needs.
