I am pleased to announce the latest title in Morgan & Claypool’s series on Information Concepts, Retrieval, and Services: Predicting Information Retrieval Performance Robert M. Losee, University of North Carolina, Chapel Hill Paperback ISBN: 9781681734729 eBook ISBN: 9781681734736 Hardcover ISBN: 9781681734743 December 2018, 80 pages http://www.morganclaypoolpublishers.com/catalog_Orig/product_info.php?products_id=1350 Abstract: Information Retrieval performance measures are usually retrospective in nature, representing the effectiveness of an experimental process. However, in the sciences, phenomena may be predicted, given parameter values of the system. After developing a measure that can be applied retrospectively or can be predicted, performance of a system using a single term can be predicted given several different types of probabilistic distributions. Information Retrieval performance can be predicted with multiple terms, where statistical dependence between terms exists and is understood. These predictive models may be applied to realistic problems, and then the results may be used to validate the accuracy of the methods used. The application of metadata or index labels can be used to determine whether or not these features should be used in particular cases. Linguistic information, such as part-of-speech tag information, can increase the discrimination value of existing terminology and can be studied predictively. This work provides methods for measuring performance that may be used predictively. Means of predicting these performance measures are provided, both for the simple case of a single term in the query and for multiple terms. Methods of applying these formulae are also suggested.
