The PROBADO project is a research effort to develop and operate advanced Digital Library support for non-textual documents. The main goal is to contribute to all parts of the Digital Library work flow from content acquisition over indexing to search and presentation. While not limited in terms of supported document types, reference support is developed for classical digital music ...

NSF’s NSDL is composed of domain-oriented pathways. Ensemble is the pathway for computing and supports the full range of computing education communities, providing a base for the development of programs that blend computing with other STEM areas (e.g., X-informatics and Computing + X), and producing digital library innovations that can be propagated to other NSDL pathways. Computing ...

In this demonstration, we present a flexible system that enables the provision of personalized functionalities to digital libraries. The system has been developed based on the needs of The European Library portal and will be demonstrated in that particular context, but could be applied more generally. It implements a broad set of data processing, analysis, and mining techniques over the ...

A traditional library is a social place, however the social nature of the library is typically lost when the library goes digital. This paper argues social navigation, an important group of social information access techniques, could be used to replicate some social features of traditional libraries and to enhance the user experience. Using the case of Ensemble, a major educational ...

Digital Library (DL) interoperability requires addressing a variety of issues associated with functionality. We report on the analysis and solutions identified by the Functionality Working Group of the DL.org project during its deliberations on DL interoperability. Ultimately, we hope that work based on our perspective will lead to improved architectures and software, as well as to greater interoperability, for ...

In this paper we present the digital library assistant (DiLiA). The system aims at augmenting the search in digital libraries in several dimensions. In the project advanced information visualisation methods are developed for user controlled interactive search. The interaction model has been designed in a way that it is transparent to the user and easy to use. In addition, information ...

Eye-tracking data was gathered as part of a user and functional evaluation of the Europeana v1.0 prototype, to determine which areas of the interface screen are most heavily used and which areas attract users’ attention but are not effectively used in search. Outputs from eye-tracking data can offer insight into how advanced search functions can be made ...

This poster will outline the Digitisation Strategy Toolkit created as part of the LIFE-SHARE project. The toolkit is based on the lifecycle model created by the LIFE project and explores the creation, acquisition, ingest, preservation (bit-stream and content) and access requirements for a digitisation strategy. This covers the policies and infrastructure required in libraries to establish successful practices. ...

The creation of most digital objects occurs solely in interactive graphical user interfaces which were available at a particular time period. Archiving and preservation organizations are posed with large amounts of such objects of various types. At some point they will need to automatically process these to make them available to their users or convert them to a commonly used ...

VOICE is a tool for cataloguing digital images using a voice-based user interface. The goal of VOICE is to ease the introduction of descriptive metadata associated to single images or collections of pictures, so that the data entered can be used later for keyword-based image retrieval. We have developed two versions of the tool, standalone VOICE and VOICE4Picasa. ...

Parasitology is a basic course in life sciences curricula, but up to now it has few computer-assisted teaching tools. We present SuperIDR, a tool which supports annotation and search (based on a textual and a visual description) in the biodiversity domain. In addition, it provides a feature to aid comparison of morphological characteristics among different species. Preliminary results with ...

This paper presents the design, implementation and evaluation of a query suggestion tool (named i-TEL-u) that allows for the management and the exploitation of different contexts in an integrated way within the same search interface for accessing the contents of The European Library portal. i-TEL-u allows users to seamlessly move from one context to another according ...

This research explores and demonstrates the process of setting up a 3D representation of a typical web-based digital library called ‘The Digital Bleek and Lloyd collection (lloydbleekcollection.cs.uct.ac.za)’ in the popular 3D virtual world, ‘Second Life’. The processes of building, scripting, and evaluation of the 3D exhibit are discussed. The report concludes that SL is ...

Digital Library support for textual and certain types of non-textual documents has significantly advanced over the last years. While Digital Library support implies many aspects along the whole library workflow model, interactive and visual retrieval allowing effective query formulation and result presentation are important functions. Recently, new kinds of non-textual documents which merit Digital Library support, but yet ...

We present results of the INEX 2009 Interactive Track which focussed on how users behave in interactive search systems. Three types of working tasks based on a collection of book metadata were regarded. The results show differences with respect to the task types and point out improvements and new research questions for the next track in 2010.

Extracting titles from a PDF’s full text is an important task in information retrieval to identify PDFs. Existing approaches apply complicated and expensive (in terms of calculating power) machine learning algorithms such as Support Vector Machines and Conditional Random Fields. In this paper we present a simple rule based heuristic, which considers style information (font size) to identify a PDF’s ...

This paper reports on current collaborative work between Taiwan e-Learning and Digital Archives Program (TELDAP) and Getty Research Institute (GRI) in developing the Chinese-language Art & Architecture Thesaurus (AAT-Taiwan) which supports the unification of terminology used by various archiving institutions for describing identical concepts. This work aims to establish a conceptual framework for the digital library by ...

There is growing recognition that exploratory search is less well supported by existing search interfaces than known-item search. In this paper, we report on a study in which three interfaces providing different levels of search support were developed and tested, for both known item and exploratory search tasks. A rich qualitative analysis of participants’ search behaviours and perceptions was ...

As universities begin to address their first significant collections of electronic records, the needs of the collections often outstrip the resources and support available. This poster will illustrate the steps taken to transition and preserve a presidential electronic records collection into an university archives with limited systems support and preparation for future preservation needs. The infrastructure created was designed to ...

Cultural heritage digital libraries hold promise both as a new tool for representing the complex information structures frequently found in the humanities and social sciences and as interactive environments that enable scholars to work with this information in new ways throughout the research project. Much attention has been paid to digitization, textual encoding, metadata and dissemination of digital cultural heritage ...

The Digital Library Curriculum Development Project (http://curric.dlib.vt.edu) team has been developing educational modules and conducting field-tests internationally since January 2006. There had been three approaches for module development in the past. The first approach was that the project team members created draft modules (total of 9) and then those modules were reviewed by the experts ...

Most digital library resources and the Web more generally are dynamic and ever-changing collections of information. However, most of the tools that have been developed for interacting with Web and DL content, such as browsers and search engines, focus on a single static snapshot of the information. In this talk, I will present analyses of how web content changes ...

Many popular web sites use folksonomies to let people label objects like images (Flickr), music (Last.fm), or URLs (Delicous) with schema-free tags. Folksonomies may reveal personal information. For example, tags can contain sensitive information, the set of tagged objects might disclose interests, etc. While many users call for sophisticated privacy mechanisms, current folksonomy systems provide coarse mechanisms at ...

This paper will report on the key findings and implications of the JISC-funded Online Catalogue and Repository Interoperability Study (OCRIS), a 3 month project which investigated the interoperability of Online Public Access Catalogues (OPACs) and Institutional Repositories (IRs) within UK Higher Education Institutions (HEIs). The aims and objectives of the project included: surveying the extent to which repository content ...

Next generation display and indexing of cataloging records are mainly influenced from the development of the FRBR conceptual model. While the process for collecting all relevant bibliographic records in a catalogue to an FRBR work entity has been extensively developed and tested in non interactive (offline) environment, the corresponding process has not been explored when meta-searching. This work presents ...

This research-in-progress paper presents a new approach called Link Proximity Analysis (LPA) for identifying related web pages based on link analysis. In contrast to current techniques, which ignore intra-page link analysis, the one put forth here examines the relative positioning of links to each other within websites. The approach uses the fact that a clear correlation between ...

Preserving digital information over the long term becomes increasing important for large number of institutions. The required expertise and limited tool support discourage especially small institutions from operating archives with digital preservation capabilities. Hoppla is an archiving solution that combines back-up and fully automated migration services for data collections in environments with limited expertise and resources for digital preservation. ...

In this work, we name Digital Library Content Laboratories (DLCLs) software systems specially devised for aggregating and elaborating over information objects – e.g., publications, experimental data, multimedia and compound objects – collected from possibly heterogeneous and autonomous data sources. We present a general-purpose and cost-efficient system for the construction of customized DLCLs, based on the D-NET Software Toolkit. ...

This paper presents Mopseus, a Fedora-commons based digital repository that focuses on preservation. An overview of the general architecture of the system is presented along with some more in-depth details of its semantic structures. Mopseus features dynamic RDF- based relations, a service for defining metadata schemas, a built-in RDBMS synchronization and indexing mechanism, a mechanism for migration ...

In this article we propose the concept of relevance criteria profiles, which provide a global view of user behaviour in judging the relevance of retrieved information. We further propose a plotting technique which provides a session based overview of the relevance judgement processes interlaced with interactions that allow the researcher to visualise and quickly detect emerging patterns in both interactions ...

Searching for entities is an emerging task in Information Retrieval for which the goal is finding well defined entities instead of documents matching the query terms. In this paper we propose a novel approach to Entity Retrieval by using Web search engine query logs. We use Markov random walks on (1) Click Graphs – built from clickthrough data – and on (2) ...

Multiple standards and encodings for names of countries, as well as multiple renderings of the country names themselves cause problems for interoperability. This impacts both human and automated processing. This paper describes an automated method for aligning pairs of country code sets by examining the string similarity between the names of the countries in each set.

The Library of Congress and other cultural institutions are collecting highly informative user-contributed metadata as comments and notes expressing historical and factual information not previously identified with a resource. In this observational study we find a number of valuable annotations added to sets of images posted by the Library of Congress on the Flickr Commons. We propose a classification ...

In the 1970’s Christopher Alexander envisioned the “pattern language”. It contains an underlying philosophy [1] of what to accomplish by using pattern language; it is this philosophy we tap into and apply to metadata planning. Different collections needs different metadata to be of future use; this information has a structure, we aim to reuse knowledge of, and standerdize the creation ...

While collaborative ltering and citation analysis have been well studied for research paper recommender systems, content-based ap- proaches typically restrict themselves to straightforward application of the vector space model. However, various types of metadata containing potentially useful information are usually available as well. Our work ex- plores several methods to exploit this information in combination with dierent similarity measures.

The status of the new media, interactive and performance art context appears to complicate our ability to follow conventional preservation approaches. Documentation of digital art materials has been determined to be an appropriate means of resolving associated difficulties, but this demands high levels of expressiveness to support the encapsulation of the myriad elements and qualities of content and context that ...

Invenio is the web-based integrated digital library system developed at CERN. Within this framework, we present four types of ranking models based on the citation graph that complement the simple approach based on citation counts: time-dependent citation counts, a relevancy ranking which extends the PageRank model, a time-dependent ranking which combines the freshness of citations with PageRank ...

We present a data model for digital libraries supporting identification, description and discovery of digital objects. The model is formalized as a first-order theory, certain models of which correspond to the intuitive notion of digital library. Our main objective is to lay the foundations for the design of an API offering the above functionality. Additionally, we use our formal ...

Presentation building applications lack good support to slide reuse. In this paper, we introduce SliDL, a digital library that facilitates slide reuse by flattening the presentation-based structure of current systems and providing slide retrieval facilities. The service-oriented architecture of SliDL enables slide sharing between different applications. We have developed clients for Microsoft PowerPoint 2007 and OpenOffice.org Impress.

The reasons why users tag have remained mostly elusive to quantitative investigations. In this paper, we distinguish between two types of motivation for tagging: While categorizers use tags mainly for categorizing resources for later browsing, describers use tags mainly for describing resources for later retrieval. To characterize users with regard to these different motivations, we introduce statistical measures and apply ...

Recent research has identified inconsistency of public library digital services, and associated problems of disparity and duplication, as a key usability issue. The hypothesis of this research is that root cause is inconsistent definition and specification of digital services, and that a service taxonomy would facilitate resolution of this issue, providing a classification scheme and controlled vocabulary. Reporting on initial ...

Funding bodies increasingly require researchers to produce Data Management Plans (DMPs). The Digital Curation Centre (DCC) has created DMP Online, a web-based tool which draws upon an analysis of funders’ requirements to enable researchers to create and export customisable DMPs, both at the grant application stage and during the project’s lifetime.

In this paper we present a new framework for editing that we have called Seaweed (short for seamless web editing) which enables authors to directly edit content on web pages within any common web browser—much like a word-processor—without the need of switching between modes. There are numerous ways to utilise the technique. This article reports on work ...

Collection selection is traditionally a sub-problem of meta-search, and identifies collections most likely to contain relevant documents. However, we propose to treat collection selection as an independent search task with the goal of identifying collections that are relevant as a whole; so the user may return to them to serve future (related) information needs. Using a new methodology ...

In this paper we present first results for a new approach of an innovative user interface for digital library and information retrieval systems. The leading thought bases on the fact that only the dialog between user and system can establish a necessary information context in order to satisfy an information need. We introduce a framework for information retrieval systems to ...

A well-known challenge of information retrieval is how to infer a user’s underlying information need when the input query consists of only a few keywords. Question Answering (QA) systems face an equally important but opposite challenge: given a verbose question, how can the system infer the relative importance of terms in order to differentiate the core information need from ...

It is popular nowadays to bring techniques from bibliometrics and scientometrics into the world of digital libraries to analyze the collaboration patterns and explore mechanisms which underlie community development. In this paper we use the DBLP data to investigate the author's scientific career and provide an in-depth exploration of some of the computer science communities. We compare them ...

In this paper we address the problem of generating an image collection visualization in which images and text can be projected together. Given a collection of images with attached text annotations, we aim to find a common representation for both information sources to model latent correlations among the collection. Using the proposed latent representation, an image collection visualization is built, ...

In Information Retrieval collections are often considered to be relatively dynamic or diverse, but no general definition has been given for these notions and no actual measure has been proposed to quantify them. We give intuitive definitions of the dynamicity and diversity properties of text collections and present measures for calculating them based on the notion of novelty. Experimental results ...

More and more large repositories of texts which must be automatically processed represent their content through the use of descriptive markup languages. This method has been diffused by the availability of widely adopted standards like SGML and, later, XML, which made possible the definition of specific formats for many kinds of text, from literary texts (TEI) to web pages (XHTML). ...

We describe a topic-specific Web search system focused on quality pages and argue that there is a need for such quality-based topic-specific search tools. The first implementation of the search system is available on the Web and it deals with climate change. The key idea is to crawl (using a focused crawling technique) in known trusted sites ...

We consider how the construction of multi-structured documents implies the definition of structuration vocabularies. In a multi-users context, the growth of these vocabularies has to be controlled. Therefore, we propose using the trace of users activity to limit this growth and document the vocabularies. A user will, for example, be able to follow and annotate the track of ...

Today, digital libraries more and more have to rely on semantic techniques during the workflows of metadata generation, search and navigational access. But, due to the statistical and/or collaborative nature of such techniques, the underlying quality of automatically generated metadata is questionable. Since data quality is essential in digital libraries, we present a user study on one hand evaluating ...

Music services, media players and managers provide support for content classification and access based on filtering metadata values, statistics of access, and user ratings. This approach fails to capture characteristics of mood and personal history that are often the deciding factor when creating personal playlists and collections in music. This paper presents MusicWiz, a music management environment that combines traditional ...

Evaluations of search features used in digital library environments are generally results centric, focussing on the outcome of an evaluation - for example, the number of relevant documents retrieved - rather than garnering an understanding of why that result was achieved. This paper explores how search feature development benefits from user-centered evaluation. By examining the application of an established web analytics ...

The estimate of digitization costs is a very difficult task. It is difficult to make exact predictions due to the great quantity of unknown factors. However, digitization projects need to have a precise idea of the economic costs and the times involved in the development of their contents. The common practice when we start digitizing a new collection is to ...

In this paper, we report the design of an RFID sensing infrastructure for digital libraries. In addition to the architecture of the system, we report its deployment in three different applications to illustrate its use and integration with not only the core DL software, but also web browsers and software for reading documents (e.g. in PDF format). Through this, ...

This paper proposes a methodology for effectiveness evaluation in content-based image retrieval systems. The methodology is based on the opinion of real users. This paper also presents the results of using this methodology to evaluate color descriptors for Web image retrieval. The experiments were performed using a database containing more than 230 thousand heterogeneous images that represents the existing ...

caT, a Petri net-based hypertext system, serves as a platform for unified modeling of digital library infrastructure and its governing policies, user characteristics, and their contextual information. Traditionally, users have created caT networks from scratch, thus limiting their use to small collections. In this paper we introduce TcAT, a component-based authoring tool, which enables the creation of large ...

Collaboratively created online encyclopedias have become increasingly popular. Especially in terms of completeness they have begun to surpass their printed counterparts. Two German publishers of traditional encyclopedias have reacted to this challenge and decided to merge their corpora to create a single more complete encyclopedia. The crucial step in this merge process is the alignment of articles. We have developed ...

Collaborative tagging has become popular in recent years. As was noted in several studies completely dierent types of tags are found. Tags either can refer to the personal usage context of a tagger or can describe the tagged object. We investigate dierent types of tags found in LibraryThing, an online service in which books are tagged, and dene a number ...

This paper reports on a user-centered evaluation of visual video summaries. We evaluated four types of summaries (fastforward, user-controlled fastforward, scene clips and storyboard) with a set of existing performance and satisfaction measures. We further conducted a repertory grid elicitation with our participants gathering evaluation constructs related to both video summary content and controls. Results showed a lack ...

This poster presents the work matching system implemented in The European Library for identifying different publications with the same underlying intellectual work. This work is contextualized in the rights management framework of project ARROW, where The European Library is the main source of bibliographic metadata as an aggregator of Europe’s national library catalogues.
