DigiMe - Ubiquitous Search and Browsing for Digital Libraries

Vast sources of information, such as the Internet are difficult to browse and/or search through. Existing tools can be sometimes frustrating for many people. So far a number of techniques have been proposed to deliver user-oriented solutions. The problem re-surfaces however within a ubiquitous computing paradigm. Aside from a possible delay in response time, their are additional drawbacks with respect to mobile devices such as: Bandwidth size, storage(what type of costs do you mean) and performance costs and client UI size. In this paper we introduce three search and browsing features: fulltext search, collaborative filtering and multifaceted browsing, all of which can be enriched with semantic and community information. We present two of the aforementioned techniques implemented in our interface for digital libraries - DigiMe.

JeromeDL: The Social Semantic Digital Library

The initial research on semantic digital libraries [115] resulted in the design and implementation of JeromeDL [118]; current research on online social networking and information discovery delivered new sets of features that were implemented in JeromeDL. Eventually, this digital library has been redesigned to follow the architecture of a social semantic digital library (see Chapter “Architecture of Semantic Digital Libraries” and Sect. 6). JeromeDL describes each resource using three types of metadata (see Fig. 2): structure, bibliographic (see Chapter “Digital Libraries and Knowledge Organization” and Chapter “Bibliographic Ontology”) and community (see Chapter “Community-aware Ontologies”). It delivers services leveraging each of these information types. Annotations based on the structure and legacy metadata (see Sect. 2), and bibliographic ontology (see Sect. 3) are rendered to the users in one, mixed, representation of library resources (see Fig. 1). Community annotations are managed by separate services, such as social semantic collaborative filtering [117] or blogging component (see Sect. 4.1 and Sect. 4).
