“…The concluding phase of the archival lifecycle is the retrieval of information from a long‐term store for use by researchers and other consumers. Hoang et al (2006) have designed a Virtual Query System of SemanticLIFE that seeks to direct emerging semantic web technologies towards the task of creating a personal information management system for an individual's lifetime data. In the slightly different context of usability and ubiquitous computing, Crabtree et al (2006) are developing procedures for the exploitation of digital records, e.g.…”

Purpose -This paper aims to set out a coherent intellectual framework to help to better understand how people create, organise, manage, use and dispose of their personal digital archives. The context for this is the increasing volume and diversity of digital information objects being captured and stored by individuals in their personal capacities and the need to find ways to preserve this material for posterity. Design/methodology/approach -The research presented here is based on literature analysis, the questions having been informed by an earlier series of in-depth interviews. The approach taken is to synthesise key concepts from the computer science, information management, and archives and records management literatures. Key concepts from the existing literature in computer science, information management, and archives and records management were elicited and synthesised to create a coherent document lifecycle narrative. Findings -Individuals exhibit great diversity in terms of personal information management and digital archiving practice at just about every point in the digital information cycle: much more so than is the case in formal repositories. Practices exhibited are not always conducive to efficient document management. This represents a very keen challenge for professional curatorial practice. Practical implications -Little is known about how individuals manage digital information resources in their personal capacity, outside of their corporate or institutional employment. Yet both individuals on their own and professional curators on behalf of repositories are increasingly being faced with the challenge of how to deal with digital media. It is hoped that this paper will contribute to a growing debate in this area. Originality/value -Personal information management from the perspective of personal digital archives is a surprisingly under-researched area and the proposed model adopts an archival information lifecycle approach. It seeks to apply and promote an archivally-oriented personal information management.

“…In PIM systems, effectively retrieving information from a huge amount data of an individual is a challenging issue. The virtual query system (VQS) (Hoang, Andjomshoaa, & Tjoa, 2006) of the SemanticLIFE framework is an approach of using semantic Web techniques with a user-oriented method in order to tackle this challenge.…”

Formulating unambiguous queries in the Semantic Web applications is a challenging task for users. This article presents a new approach in guiding users to formulate clear requests based on their common nature of querying for information. The approach known as the front-end ap proach gives users an overview about the system data through a vir tual data component which stores the extracted metadata of the data storage sources in the form of an ontology. This approach reduces the ambiguities in users' requests at a very early stage and allows the query process to effectively perform in fulfilling users' demands in a context-aware manner. Furthermore, the approach provides a powerful query engine, called context-aware query ing, that recommends the appropriate query patterns according to the user's querying context.

“…24,21,8,16] as well as ontology based query expansion [e.g. 6,26] have enhanced techniques for semantic search applications. In order to implement a solution and make improvements to a search engine of an ISN, future research includes a detailed observation of more ontology based query expansion approaches to use the "Semiotic Web ontology" method.…”

“…There are several architectural proposals for semantic search solutions. Mangold [39], Wang et al [79], Hoang & Tjoa [26] and Hildebrand et al [25] have made an extensive revision of the main proposals of semantic search solutions in the literature. They describe open research questions, and necessary investigations, as well as similarities, goals, applications, methodologies and technologies involved in the various proposals.…”

“…The ISM was developed as Web Services connected to the Drupal modules and the ISN modules. Information such as the index, the agents and user-agent modeling are stored in a PostgreSQL 26 8.3 database. The ISM Web Services manage all the necessary information and provides all the services to handle the search request, the index processing, the adding of agents and user-agent relationship, as well as the ontology management for getting meanings and query expansion.…”

Busca informada por abordagem semiótica em redes sociais inclusivas online

As Redes Sociais Online (RSOs) podem representar uma oportunidade para as pessoas não letradas digitalmente efetivamente familiarizarem-se com tecnologias da informação e comunicação. Para isso, esses sistemas deveriam prover acesso inclusivo, criando situações nas quais a diversidade cultural dos usuários fosse respeitada, e suas dificuldades de acesso minimizadas. RSOs com recursos que promovam acesso a todos, incluindo aqueles às margens da cultura digital, podem ser definidas como Redes Sociais Inclusivas (RSIs). Nestas, as pessoas devem ter a possibilidade de facilmente recuperarem informações corretas, e principalmente que façam sentido a elas.Nesse contexto, o objetivo deste trabalho é investigar a concepção de mecanismos de busca inclusivos, mais adequados ao conceito de RSI, que possam propiciar resultados de busca mais significativos e personalizados. Embora o uso de mecanismos de busca seja uma das principais alternativas para acessar informação na Web atualmente, esses mecanismos ainda são construídos principalmente através de processamento léxico-sintático da informação, resultando em barreiras para muitos usuários. O uso de técnicas de busca semântica impulsionado por tecnologias da Web Semântica (WS) apresenta novas possibilidades para o problema em destaque, mas estas ainda são fundamentadas em paradigmas e métodos limitados para a representação do conhecimento em redes sociais.Para desenvolver um mecanismo de busca inclusivo em RSI é preciso "interpretar" a semântica compartilhada pelas pessoas. Nesta direção é necessário utilizar abordagens e métodos que permitam capturar os aspectos sociais e culturais advindos da rede social, como a linguagem coloquial e as relações semânticas usadas. Desta maneira, o mecanismo de busca inclusivo proposto adota uma solução baseada em ontologias, que são construídas com base em uma nova abordagem para o design de ontologias Web. Esta abordagem é fundamentada em conceitos e métodos da Semiótica Organizacional (SO), combinados com tecnologias da WS. A concepção desta abordagem foi inspirada em resultados de um experimento com usuários reais sobre atividades de busca em um sistema de RSI. A solução proposta pode possibilitar novas estratégias de busca baseadas em ontologia, e conseqüentemente, gerar a possibilidade de promover o acesso participativo e universal ao conhecimento.
