News Archives constitute an important source for historians, both for research and educational purposes. However, access to their material is not easy due to the special characteristics of the…
Many applications offer a form-based environment for naive users for accessing databases without being familiar with the database schema or a structured query language. User interactions are…
On-line analytical processing (OLAP) typically involves complex aggregate queries over large datasets. The data cube has been proposed as a structure that materializes the results of such queries…

The BioMagResBank (BMRB: www.bmrb.wisc.edu) is a repository for experimental and derived data gathered from nuclear magnetic resonance (NMR) spectroscopic studies of biological molecules. BMRB is a…
DelosDLMS: From the DELOS Vision to the Implementation of a Future Digital Library Management System
DelosDLMS is a novel digital library management system (DLMS) that has been developed as an integration effort within the DELOS Network of Excellence, a European Commission initiative funded…

Database research is expanding, with major efforts in system architecture, new languages, cloud services, mobile and virtual worlds, and interplay between structure and text.
The lifecycle of a data cube involves efficient construction and storage, fast query answering, and incremental updating. Existing ROLAP methods that implement data cubes are weak with respect to…
There has been much work in the past that combines the fields of Databases and Natural Language Processing. Almost all efforts, however, have gone in one direction: given unstructured, natural-…
Ontologies offer a flexible and expressive layer of abstraction, very useful for capturing the semantics of information repositories and facilitating their retrieval either by the user or by the…
In the classical database world, information access has been based on a paradigm that involves structured, schema-aware, queries and tabular answers. In the current environment, however, where…

At the end of last century (Internet time elapses much quicker than normal time, and it already looks like a long time ago), the “information explosion” on the Web on one side, and the flourishing…
There has been much work in the past that combines the fields of Databases and Natural Language Processing. Almost all efforts, however, have gone in one direction: given unstructured, natural-…
Précis queries represent a novel way of accessing data, which combines ideas and techniques from the fields of databases and information retrieval. They are free-form, keyword-based, queries on top…

Implementation of the data cube is an important and scientifically interesting issue in On-Line Analytical Processing (OLAP) and has been the subject of a plethora of related publications. Naive…
This book constitutes the refereed proceedings of the 11th East European Conference on Advances in Databases and Information Systems, ADBIS 2007, held in Varna, Bulgaria, in September/October 2007…
In large-scale distributed retrieval, challenges of latency, heterogeneity, and dynamicity emphasise the importance of infrastructural support in reducing the development costs of state-of-the-art…
As a large fraction of available information resides in databases, the need for facilitating access for the large majority of users becomes increasingly more important. Precis queries are free-form…
The term "Digital Libraries" corresponds to a very complex notion with several diverse aspects and cannot be captured by a simple definition. A robust model of Digital Libraries encapsulating the…
Open Agoras of information are distributed environments of independent systems, where seeking for information is similar to real-life searching for material goods. Interaction with these systems…
In large federations of autonomous database systems, automatic distribution of the query workload to those systems is a critical issue. We examine this problem under the perspective of…

Data cube construction has been the focus of much research due to its importance in improving efficiency of OLAP. A significant fraction of this work has been on ROLAP techniques, which are based…
Conventional data management occurs primarily in centralized servers or in well-interconnected distributed systems. These are removed from their end users, who interact with the systems mostly…
Large-scale distributed environments, where each node is completely autonomous and offers services to its peers through external communication, pose significant challenges to query processing and…
In this paper we describe briefly three systems: onCue a desktop internet-access toolbar, Snip!t a web-based bookmarking application and ontoPIM an ontology-based personal task-management system.…
This book constitutes the refereed proceedings of the 10th International Conference on Extending Database Technology, EDBT 2006, held in Munich, Germany, in March 2006. The 60 revised research papers…
Wide spread use of database systems in modern society has brought the need to provide inexperienced users with the ability to easily search a database with no specific knowledge of a query language…

The traditional interaction mechanism with a database system is through the use of a query language, the most widely used one being SQL. However, when one is facing a situation where he or she has…
Nowadays, our personal computer contains a huge amount of information, that is stored in several different formats. When looking for an information, one possibility is to use a keyword-based search…

Personalization of keyword searches has attracted interest in the research community as a means to decrease search ambiguity and return results that are more bound to be interesting to a particular…
The DELOS network of excellence is a European initiative that has been funded by the European Commission under its fifth and sixth framework programs. It has played a significant role in the…
Personal Information Management (PIM) aims to support users in the collection, storage and retrieval of their personal information. In such a framework the focus is mainly on how better to handle…
Database needs are changing, driven by the Internet and increasing amounts of scientific and sensor data. In this article, the authors propose research into several important new directions for…
Query Personalization is the process of dynamically enhancing a query with related user preferences stored in a user profile with the aim of providing personalized answers. The underlying idea is…
