Clustering in information retrieval
WebCluster-based retrieval is based on the hypothesis that similar documents will match the same information needs [20]. In document-based retrieval, an information retrieval (IR) system matches the query against documents in the collection and returns a ranked list of documents to the user. Cluster-based retrieval, on WebApr 8, 2024 · Clustering traditionally consists in partitioning data into subsets of similar instances with no prior knowledge on the clusters to be obtained. 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.

WebNov 16, 2024 · Deep hashing has shown promising performance in large-scale image retrieval. The hashing process utilizes Deep Neural Networks (DNNs) to embed images into compact continuous latent codes, then map them into binary codes by hashing function for efficient retrieval. Recent approaches perform metric loss and quantization loss to … 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 …
WebJul 1, 2024 · This section presents the proposed ICIR (Intelligent Cluster-based Information Retrieval) approach, which employs both clustering and frequent itemset mining to improve the quality of documents retrieved using a cluster-based information retrieval approach. The designed approach consists of two main steps. Webinformation can be augmented by recognizing additional concept terms from the video and by computing similarities between content samples [4]. Relevance feedback improves the content-based retrieval performance by incorporating information from prior relevance judgments [5]. In [6] cluster-temporal browsing was introduced as an
