Evaluating subtopic retrieval methods: Clustering versus diversification of search results
To address the inability of current ranking systems to support subtopic retrieval, two main post-processing techniques of search results have been investigated: clustering and diversification. In this paper we present a comparative study of their performance, using a set of complementary evaluation measures that can be applied to both partitions and ranked lists, and two specialized test collec...
متن کاملEvaluating Hierarchical Clustering of Search Results
We propose a goal-oriented evaluation measure, Hierarchy Quality, for hierarchical clustering algorithms applied to the task of organizing search results -such as the clusters generated by Vivisimo search engine-. Our metric considers the content of the clusters, their hierarchical arrangement, and the effort required to find relevant information by traversing the hierarchy starting from the to...
متن کاملQuery Subtopic Mining Exploiting Word Embedding for Search Result Diversification
Understanding the users’ search intents through mining query subtopic is a challenging task and a prerequisite step for search diversification. This paper proposes mining query subtopic by exploiting the word embedding and short-text similarity measure. We extract candidate subtopic from multiple sources and introduce a new way of ranking based on a new novelty estimation that faithfully repres...
متن کاملTemporal Diversification of Search Results
We investigate the notion of temporal diversity, bringing together two recently active threads of research, namely temporal ranking and diversification of search results. A novel method is developed to determine search results consisting of documents that are relevant to the query and were published at diverse times of interest to the query. Preliminary experiments on twenty years’ worth of new...
متن کاملAdaptive Clustering of Search Results in Interactive Information Retrieval
Clustering of search results has been shown to be advantageous over the simple list presentation of search results. However, in most clustering interfaces, the clusters are not adaptive to a user’s interaction with the clustering results, and the important question “how to optimize the benefit of a clustering interface for a user” has not been well addressed in the previous work. In this paper,...
