This book constitutes the refereed proceedings of the 16th International Conference on Flexible Query Answering Systems, FQAS 2025, held in Burgas, Bulgaria, during September 11–13, 2025.The 26 full papers presented were carefully reviewed and selected from 49 submissions. The proceedings also include 3 invited talk and 2 tutorial papers. They were organized in the following topical sections: Invited Talks; Flexible Query Answering Systems; Data-driven Quality Management and Intelligent Systems for Academic Processes and Flexible Decision-making; Language Models in Advanced Information Retrieval; Intuitionistic Fuzzy Approaches for Flexible Querying and Reasoning under Uncertainty; and Emerging Trends in Flexible Query Answering and Information Retrieval.

This book, written by an international team of prominent authors, gathers the latest developments in mobile technologies for the acquisition, management, analysis and sharing of Volunteered Geographic Information (VGI) in the context of Earth observation.  It is divided into three parts, the first of which presents case studies on the implementation of VGI for Earth observation, discusses the characteristics of volunteers’ engagement in relation with their expertise and motivation, analyzes the tasks they are called upon to perform, and examines the available tools for developing VGI. In turn, the second part introduces readers to essential methods, techniques and algorithms used to develop mobile information systems based on VGI for distinct Earth observation tasks, while the last part focuses on the drawbacks and limitations of VGI with regard to the above-mentioned tasks and proposes innovative methods and techniques to help overcome them. Given its breadth of coverage, the bookoffers a comprehensive, practice-oriented reference guide for researchers and practitioners in the field of geo-information management.

Spatio-Temporal Databases explores recent trends in flexible querying and reasoning about time- and space-related information in databases.

A more intuitive, easy and powerful representation, access, and retrieval of information is nowadays a necessary feature of information systems that have become a common instrument for a wide class of users in di?erent areas and for the most diversi?ed tasks. The management of imprecision and uncertainty in databases has become an important research area, which has known an impressive growth. This is testi?ed the increasing number of special sessions in international conferences and workshops devoted to this theme. Generally, this topic matured and developed independently within both the traditional database community and the community of researchers on fuzzy sets, and only very recently some joint initiatives have been undertaken. Since the Workshop titled “Supporting Imprecision and Uncertainty in Flexible DataBases” we organized within the DEXA Conference in Zaragoza on August 2004, our intent is to bring together a wide community of - searchers in the ?eld of databases, Information Retrieval, Spatial Information Systems, knowledge representation and multimedia, to share experiences and methods concerning the management of uncertainty and imprecision in da- bases. This volume collects a selected number of contributions of well known pioneerresearcheswho,atvariouslevels,proposedmodelsandtheapplication ofmethodstorepresentandmanageuncertaintyandimprecisionindatabases. Many approaches have been proposed in the literature on the modelling of uncertainty and imprecision in databases. To o?er a panoramic view of the methods proposed so far to students, researchers and insightful practitioners, we included in the volume survey chapters on classic topics such as ?exible querying in databases, and database models to represent imperfect data.

Spatio-Temporal Databases explores recent trends in flexible querying and reasoning about time- and space-related information in databases. It shows how flexible querying enhances standard querying expressiveness in many different ways, with the aim of facilitating extraction of relevant data and information. Flexible spatial and temporal reasoning denotes qualitative reasoning about dynamic changes in the spatial domain, characterized by imprecision or uncertainty (or both). Many of the contributions focus on GIS, while some others are more general, or focus on related application fields, presenting theoretical viewpoints and techniques that are inspiring or can be adapted for GIS. The first part bundles the contributions on advances at the theoretical level, also discussing examples and opening further perspectives. The second part presents contributions on well-developed applications. The authors explain how to handle imprecision and uncertainty, demonstrating how advanced techniques can help to solve diverse problems related to GIS.

This research volume presents a sample of recent contributions related to the issue of quality-assessment for Web Based information in the context of information access, retrieval, and filtering systems.The advent of the Web and the uncontrolled process of documents' generation have raised the problem of declining quality assessment to information on the Web, by considering both the nature of documents (texts, images, video, sounds, and so on), the genre of documents ( news, geographic information, ontologies, medical records, products records, and so on), the reputation of information sources and sites, and, last but not least the actions performed on documents (content indexing, retrieval and ranking, collaborative filtering, and so on).The volume constitutes a compendium of both heterogeneous approaches and sample applications focusing specific aspects of the quality assessment for Web-based information for researchers, PhD students and practitioners carrying out their research activity in the field of Web information retrieval and filtering, Web information mining, information quality representation and management.

This book focuses on the recent research issues regarding the application of fuzzy set theory to extend the functionalities of database management systems.During the past 5 years, the research in this field has moved from a merely theoretical framework mainly addressing the definition of fuzzy extensions of the relational database model to the consideration of other, object-oriented database paradigms, also in relation to their implementation and application in specific contexts (e.g. geographic information systems), fuzzy data mining, and fuzzy functional dependencies definition.Besides contributing to stimulating interest in the field of fuzzy databases, the book aims to show that the research carried out so far has matured some fuzzy extensions of classical databases that are feasible to be implemented and applied fruitfully in real applications.
