Purpose With the rapid development in the internet technologies, the applications of big data in construction have seen considerable attention. Currently, there are many input/output modes of capturing construction knowledge related to all construction stages. On the other hand, building information modelling (BIM) systems have been developed to help in storing various structured data of buildings. However, these systems cannot fully capture the knowledge and unstructured data used in the operation of building systems in a usable format that uses the intelligent capabilities of BIM systems. Therefore, this research aims to adopt the concept of big data and develop a spoken dialogue BIM system to capture buildings operation knowledge, particularly for building maintenance and refurbishment. Design/methodology/approach The proposed system integrates cloud-based spoken dialogue system and case-based reasoning BIM system. Findings The system acts as an interactive expert agent that seeks answers from the user for questions specific to building maintenance problems and helps searching for solutions from previously stored knowledge cases. The practices of monitoring and maintaining buildings performance can be more efficient by the retrieval of relevant solutions from the captured knowledge to new problems when maintaining buildings components. The developed system enables easier capture and search for solutions to new problems with a more comprehensive retrieval of information. Originality/value Capturing multi-modes data into BIM systems using the cloud-based spoken dialogue systems will help construction teams use the high volume of data generated over building lifecycle and search for the most suitable solutions for maintenance problems. This new area of research also contributes to the current BIM systems by advancing their capabilities to instantly capture and retrieve knowledge of operations instead of only information.

PurposeThe purpose of this paper is to explore young people’s conceptions of political information. The study sought to identify what political information sources young people encounter, how they construe these sources and the messages they communicate, and how the information experiences of young people may be better understood to inform information literacy interventions to support the development of political agency.Design/methodology/approachUsing personal construct theory as a conceptual framework, repertory grid (RG) interviews were used to explore the different ways in which 23 young people aged 14-15 from a town in Northern England conceive of political information and how they evaluate its quality and authority.FindingsThe study identified the sources of information young people engage with for finding and receiving what they understand as political information. The results from the RG interviews indicated that young people use a wide range of sources of political information to become informed about politics and the world around them. These sources of information include family, friends, teachers, television news, newspapers, radio shows, comedy shows, social media and community meetings. Participants were aware that they passively encounter information sources as well as actively engage in debate and discussion with other sources. Some participants had difficulty critically evaluating the political information sources they encounter. The nature of young people’s experiences of political information varied greatly. The degree of complexity in the experiences of political information varied not only between participants but was also dependent on their particular relationship with the information sources under scrutiny.Research limitations/implicationsThe paper has implications for personal construct analysis as a research approach broadly, from the point of view of its use within library and information science research. It is the first study to apply the personal construct approach to the study of young people’s political information use and to consider implications for information literacy support that would have been difficult to access using other approaches.Practical implicationsThe paper provides insight into an understudied area; that of young people’s conceptions of political information. This insight may be used to inform the improvement of political information provision and information literacy support for young people.Social implicationsA deeper understanding of the different ways in which young people identify, engage with and use information for political purposes may contribute to a clearer understanding of young people’s information needs, ideally leading to improved political education and a strengthened democratic process.Originality/valueThe paper explores a relatively under-researched area of library and information science research, and does so using a relatively under-used method in the domain. Insights into the perceived characteristics of different sources of political information are novel and contribute to the development of information behaviour and information literacy fields in terms of information for empowerment and democracy.

PurposeAims at providing a broad overview of some of the issues emerging from the growth in open access publishing, with specific reference to the use of repositories and open access journals.Design/methodology/approachA paper largely based on specific experience with institutional repositories and the internationally run E‐library and information science (LIS) archive.FindingsThe open access initiative is dramatically transforming the process of scholarly communication bringing great benefits to the academic world with an, as yet, uncertain outcome for commercial publishers.Practical implicationsOutlines the benefits of the open access movement with reference to repositories and open access journals to authors and readers alike and gives some food for thought on potential barriers to the complete permeation of the open access model, such as copyright restrictions and version control issues. Some illustrative examples of country‐specific initiatives and the international E‐LIS venture are given.Originality/valueAn attempt to introduce general theories and practical implications of the open access movement to those largely unfamiliar with the movement.

Purpose Community libraries now constitute a significant proportion of library provision in the UK; however, there is relatively little research on how the transfer to this model has affected those libraries and the wider balance of provision. The purpose of this paper is to broaden the discourse and understanding about the impact of changing libraries to community models. Design/methodology/approach The paper provides a qualitative evaluation of all the libraries transferred to community-managed models within a large city council region in the UK. Structured research visits were made to appraise each library. These are discussed in the context of published literature and data, both specific to the study area and nationally. Findings Transferring the management of libraries to community organisations is often reactive and perceived with negative associations. This study uncovers increases in use and diversification of services following transfer; however, support from the local authority and the previous experience of managing organisations are significant factors. The paper also reveals how the successful transfer of a library to a community organisation led to more being moved out of local authority control, but that the support they receive from the local authority can be inconsistent between them. Originality/value The paper provides a study of community-managed libraries across a large city council area, affording an in-depth understanding of their impact on overall provision over one region. It will be of value to those involved in library management and service provision at both local and strategic levels, including local authorities and community groups considering library transfer.
