There could be various approaches to increase the quality of VRS. In this study, we focused on two key factors; improving helpfulness and reducing user's feeling of intrusiveness. Studies indicated that librarian-initiated attempts for help may increase user's feeling of intrusiveness [2] [3]. It is challenging to provide high helpfulness along with less intrusiveness in VRS. This study aimed to identify factors that contribute to improving helpfulness and reducing intrusiveness. Data were collected based on a survey using systemic random sample approach. Our initial results indicated that awareness, timing, and transparency were key factors affecting the helpfulness and intrusiveness.","PeriodicalId":92278,"journal":{"name":"Proceedings of the ...

Here, we aid such crucial task by introducing two new metrics (C-Endo and Comb) that rely on the concept of endogamy for communities of authors who publish in conferences and journals, and produce patents. Endogamy here measures how tightly structured the groups of authors are within a community. We validate and evaluate the metrics by using real datasets, two ground-truth rankings and citation count. We also perform random sampling analysis to account for any unbalance from the ground-truth rankings. Overall, such a thorough evaluation shows that our metrics are successful in defining community-based endogamy as an influence indicator.","PeriodicalId":92278,"journal":{"name":"Proceedings of the ...

To this end, we gather and conduct an exhaustive analysis on a dataset of more than 1.5 million scientific papers of computer science domain. On analysis of the dataset, we notice that the citation count of the articles over the years follows a diverse set of patterns; on closer inspection we identify six broad categories of citation patterns. This important observation motivates us to adopt stratified learning approach in the prediction task, whereby, we propose a two-stage prediction model - in the first stage, the model maps a query paper into one of the six categories, and then in the second stage a regression module is run only on the subpopulation corresponding to that category to predict the future citation count of the query paper. Experimental results show that the categorization of this huge dataset during the training phase leads to a remarkable improvement (around 50%) in comparison to the well-known baseline system.","PeriodicalId":92278,"journal":{"name":"Proceedings of the ...

This paper reports on a study exploring the behaviour of groups of patrons in physical libraries, detailing their collaboration and communication during book searches. We aim to identify how characteristics such as location, time, environment, ambiance, layout and personal motivation play a role in a group's search and browsing behaviour. We report the findings of observations of group collaboration in academic and public libraries, and compare the observed book and library use techniques employed by patron groups. Further, we examine the support for group collaboration in digital libraries and discuss the implications of our observations for the design of digital libraries that support group collaboration and interaction among users. To that end, the paper suggests features and functions that could be added to DLs to enable asynchronous group communication and interaction.","PeriodicalId":92278,"journal":{"name":"Proceedings of the ...

We present a supervised machine learning approach to assessing the “coreness” of concepts expressed by resource sentences. The algorithm has been developed and evaluated in the domain of science education where coreness refers to the degree to which a sentence embodies key concepts important to developing a robust understanding of the domain. Our method operates by automatically computing and leveraging the degree of semantic similarity between resource sentences and standard domain concepts designed by human experts for various STEM domains. In our experiments, the algorithm demonstrates high accuracy in identifying sentence coreness when there is agreement between human experts on the coreness rating. We also present performance comparisons with a number of baseline systems.","PeriodicalId":92278,"journal":{"name":"Proceedings of the ... ACM/IEEE Joint Conference on Digital Libraries.

Various methods for computing item-to-item similarities are investigated, together with representing the collection as a network over which random walks can be taken. The network can represent similarity between item metadata, item co-occurrences in search logs, and the similarity of items based on linking them to Wikipedia articles and categories. To evaluate the use of PPR, search logs from Europeana are used to simulate user interactions. PPR on each information source is compared to a standard retrieval-based baseline, resulting in higher performance.","PeriodicalId":92278,"journal":{"name":"Proceedings of the ...
