Book excerpt: "Data fusion and search result diversification are two critical research topics in information retrieval. Data fusion approaches combine search result lists in order to produce a new and hopefully better ranking. We propose two data fusion models for microblog search that exploit temporal information and infer rank scores of missing documents in the lists to be fused. We also propose a fusion method based on manifolds. The method constructs manifolds, let low ranked documents be rewarded to be relevant by high ranked documents in the same manifolds, and utilize the top-k documents as anchors to enhance the efficiency of data fusion. Search result diversification is widely being studied as a way of tackling query ambiguity. Instead of trying to identify the "correct" interpretation behind a query, the idea is to make the search results diversified so that users with different backgrounds will find at least one of these results to be relevant. We examine the hypothesis that data fusion can improve performance in terms of diversity metrics, and proposes a new data fusion method, called diversified data fusion for search result diversification. We also study the problem of personalized diversification via supervised learning, with the goal of enhancing both diversification and personalization performance. The results in this thesis show how both our proposed data fusion and search result diversification methods improve retrieval performance and how they relate to each other. The insights in this thesis may be used to improve retrieval performance for a range of tasks in information retrieval."--Samenvatting auteur.
Download or read book Data Fusion in Information Retrieval written by Shengli Wu and published by Springer Science & Business Media. This book was released on 2012-04-05 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technique of data fusion has been used extensively in information retrieval due to the complexity and diversity of tasks involved such as web and social networks, legal, enterprise, and many others. This book presents both a theoretical and empirical approach to data fusion. Several typical data fusion algorithms are discussed, analyzed and evaluated. A reader will find answers to the following questions, among others: What are the key factors that affect the performance of data fusion algorithms significantly? What conditions are favorable to data fusion algorithms? CombSum and CombMNZ, which one is better? and why? What is the rationale of using the linear combination method? How can the best fusion option be found under any given circumstances?

Download or read book Multisensor Data Fusion and Machine Learning for Environmental Remote Sensing written by Ni-Bin Chang and published by CRC Press. This book was released on 2018-02-21 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years the scientific community has realized that obtaining a better understanding of interactions between natural systems and the man-made environment across different scales demands more research efforts in remote sensing. An integrated Earth system observatory that merges surface-based, air-borne, space-borne, and even underground sensors with comprehensive and predictive capabilities indicates promise for revolutionizing the study of global water, energy, and carbon cycles as well as land use and land cover changes. The aim of this book is to present a suite of relevant concepts, tools, and methods of integrated multisensor data fusion and machine learning technologies to promote environmental sustainability. The process of machine learning for intelligent feature extraction consists of regular, deep, and fast learning algorithms. The niche for integrating data fusion and machine learning for remote sensing rests upon the creation of a new scientific architecture in remote sensing science that is designed to support numerical as well as symbolic feature extraction managed by several cognitively oriented machine learning tasks at finer scales. By grouping a suite of satellites with similar nature in platform design, data merging may come to help for cloudy pixel reconstruction over the space domain or concatenation of time series images over the time domain, or even both simultaneously. Organized in 5 parts, from Fundamental Principles of Remote Sensing; Feature Extraction for Remote Sensing; Image and Data Fusion for Remote Sensing; Integrated Data Merging, Data Reconstruction, Data Fusion, and Machine Learning; to Remote Sensing for Environmental Decision Analysis, the book will be a useful reference for graduate students, academic scholars, and working professionals who are involved in the study of Earth systems and the environment for a sustainable future. The new knowledge in this book can be applied successfully in many areas of environmental science and engineering.
