Nowadays, with the increasing amount of technologies which support the storage of data in digital format, the problem of accessing the information relevant to specific needs becomes a ubiquitous challenge. In particular, with the widespread expansion of the Internet and of the World Wide Web, myriads of databases are available online, providing massive repositories which may be accessed to reply to ordinary users' queries. On the other hand, due to the lack of knowledge about the contents of the large Web repositories and to the limited capability of the rigid standard querying interfaces, often users may not know how precisely express their needs and they may formulate queries that lead to unsatisfactory results. To improve the user friendliness of querying interfaces, as well as, to enhance querying facilities, several researchers have addressed the need for advanced systems to support user access to available information.
