Selected Papers

Probabilistic Inference over Image Networks

Abstract
Digital Libraries contain collections of multimedia objects providing services for the management, sharing and retrieval. Involved objects have two levels of complexity: the former refers to the inner object complexity while the latter takes into account the implicit/explicit relationships among objects. Traditional machine learning classifiers do not consider the relationships among objects assuming them independent and identically distributed. Recently, link-based classification methods have been proposed, that try to classify objects exploiting their relationships (links). In this paper, we deal with objects corresponding to digital images, even if the proposed approach can be naturally applied to different kind of multimedia objects. Relationships can be expressed among the features of the same image or among features belonging to different images. The aim of this work is to verify whether a link-based classifier based on a Statistical Relational Learning (SRL) language can improve the accuracy of a classical k-nearest neighbour approach. Experiments will show that the modelling of the relationships in a real-word dataset using a SRL model reduces the classification error.

A Keyphrase-Based Paper Recommender System

Abstract
Current digital libraries suffer from the information overload problem which prevents an effective access to knowledge. This is particularly true for scientific digital libraries where a growing amount of scientific articles can be explored by users with different needs, backgrounds, and interests. Recommender systems can tackle this limitation by filtering resources according to specific user needs. This paper introduces a content-based recommendation approach for enhancing the access to scientific digital libraries where a keyphrase extraction module is used to produce a rich description of both content of papers and user interests.

Accessing Music Digital Libraries by Combining Semantic Tags and Audio Content

Abstract
An interesting problem in accessing music digital libraries is how to combine the information of different sources in order to improve the retrieval effectiveness. This paper introduces an approach to represent a collection of tagged songs through an hidden Markov model with the purpose to develop a system that merges in the same framework both acoustic similarity and semantic descriptions. The former provides content-based information on song similarity, the latter provides context-aware information about individual songs. Experimental results show how the proposed model leads to better performances than approaches that rank songs using both a single information source and a their linear combination.

Improving User Stereotypes through Machine Learning Techniques

Abstract
Users of Digital libraries require more intelligent interaction functionality to satisfy their needs. In this perspective, the most important features are flexibility and capability of adapting these functionalities to specific users. However, the main problem of current systems is their inability to support different needs of individual users due both to their inability to identify those needs, and, more importantly, to insufficient mapping of those needs to the available resources/services. The approaches considered in this paper to tackle such problems concern the use of Machine Learning techniques to adapt the set of user stereotypes with the aim of modelling user interests and behaviour in order to provide the most suitable service. A purposely designed simulation scenario was exploited to show the applicability of the proposal.

Displaying Phonological Diachronic Changes through a Database Application

Abstract
This paper presents a project which aims to provide a new digital instrument for linguistic research. This new tool will be able to show the historical evolution of a language into one or more daughter languages, and it will allow users to perform a comparative and typological analysis of diachronic processes. The originality of this project is given by two factors: first, its developers are linguists with notions in computer science, which prevents any communication issue between different teams of experts; second, the data feeding database, though derived from well known corpora, have been processed in a specialist way to display the evolution of words from a mother language to the daughter languages. The instrument will account for all the diachronic phonological rules which occur during the word change.

A Digital Library of Grammatical Resources for European Dialects

Abstract
The paper illustrates the methodology at the basis of the design of a digital library system that enables the management of linguistic resources of curated dialect data. Since dialects are rarely recognized as official languages, first of all linguists need a dedicated information management system providing the unambiguous identification of each dialect on the basis of geographical, administrative and geolinguistic parameters. Secondly, the information management system has to be designed to allow users to search the occurrences of a specific grammatical structure (e.g. a relative clause or a particular word order). Thirdly, user-friendly graphical interfaces must give easy access to language resources and make the building of the language resources easier and distributed. This work, which stems from a project named ASIt (Atlante Sintattico d’Italia), is a first step towards the creation of a European digital library for recording and studying linguistic micro-variation.

Taxonomy Based Notification Service for the ASSETS Digital Library Platform

Abstract
In this paper, we report our taxonomy-based notification service for the ASSETS digital library platform, which is being developed in an EU co-funded project. Notification is a very fundamental functionality for every living digital library which is continuously updated and dynamically interacts with users. The ASSETS platform provides a common notification service and its extensions based on the publish/subscribe pattern as a message notification infrastructure. Our taxonomy based notification service is one of those extensions that enables users to define subscriptions for receiving notifications by using a hierarchically organized controlled vocabulary, namely a taxonomy. Through this service, users can easily subscribe to messages about specific domain of their interest with a small number of terms in a taxonomy. Then system can efficiently filter a stream of published messages to deliver notifications to proper subscribers by taking account of the taxonomy. This service works as an important piece for enabling various advanced features in the ASSETS platform such as personalized new item lists and a digital preservation service. In this paper, we show an outline of the ASSETS notification architecture, and give a description about a model for the taxonomy-based notification implemented in our service.

ASIt: A Grammatical Survey of Italian Dialects and Cimbrian: Fieldwork, Data Management, and Linguistic Analysis

Abstract
ASIt aims to observe, collect and analyse the linguistic variation displayed by the dialects of a language. The main theoretical hypothesis is that linguistic variation is not due to chance, but depends on the combination of a finite number of parameters. It is a first step towards the creation of a European digital library for recording and studying linguistic micro-variation.

Computational Models Enhancing Semantic Access to Digital Repositories

Abstract
The growing amount of heterogeneous digital repositories has created a demand for effective and flexible techniques for automatic multimedia data retrieval. While the primary type of information available in documents is usually text, other type of information such as images play a very important role because they pictorially describe concepts that are dealt with in the document. Unfortunately, the semantic gap separating the visual content from the underlying meaning is wide.
The main goal of the project concerns the investigation of machine learning approaches to improve the semantic access to multimedia repositories by combining information gathered from the textual content with the one coming from pictorial representation. Furthermore, they have to be scalable, efficient and robust with respect to the inborn high-dimensionality and noise in the data collection.

Project D.A.M.A.: Document Acquisition, Management and Archiving

Abstract
A paper document processing system is an information system component which transforms information on printed or handwritten documents into a computer-revisable form. In intelligent systems for paper document processing this information capture process is based on knowledge of the specific layout and logical structures of the documents. In this project we design a framework which combines technologies for the acquisition and storage of printed documents with knowledge-based techniques to represent and understand the information they contain. The innovative aspects of this work strengthen its applicability to tools that have been developed for building digital libraries.

Cooperative Digital Asset Management in the Scientific Field: Strategies, Policies, Interoperability and Persistent Identifiers

Abstract
In this paper we present a series of activities carried out within the National Research Council of Italy (CNR) and aimed at the development of a unique, certified and open archive of CNR’s digital research products. Starting from the description of CNR’s distributed library system, we then briefly talk about CNR’s involvement in OA initiatives and the role played by CNR’s Information System Office in providing technological tools for digital asset management. Afterwards we try to point out some criticalities of OA archives. We then talk about the solution we propose for the development of a unique, certified and open archive using a cooperative approach that takes into account previous experiences, existing repositories, policy and organizational issues. We also present the processes we designed for content ingestion and validation and the strategies for persistent identification. We finally illustrate the technical solutions we have developed as prototype proposals for the community.
