This publication constitutes the completely refereed submit complaints of 2 overseas workshops on specified elements of electronic libraries, particularly the 1st overseas Workshop on usual Language Processing for electronic Libraries, NLP4DL 2009, held in Viareggio, Italy in June 2009 and the CACAO undertaking Workshop complicated applied sciences for electronic Libraries, AT4DL 2009, held in Trento, Italy in September 2009.
A new open name was once despatched after the workshops. The revised complete papers offered on the workshops and the newly submitted ones went via rounds of reviewing and revision. the ten papers chosen handle numerous features of NLP in electronic libraries, seek, type, and electronic rfile processing.

One possibility is to exploit it in order to build knowledge structures that can assist in interactive search. But do users want assisted search? First of all, digital libraries are characterized by much more structured knowledge than Web sites. This makes systemguided search a natural option as evidenced by the success of Aquabrowser2 as a tool to access digital libraries. More generally though, there is also evidence that users want support in proposing keywords but they ultimately want to stay in control about what is being submitted as a query [50].
