A semantic engine for grey literature retrieval in the oceanography domain
No full textHere we present the final results of the MAPS (Marine Planning and Service Platform) project, an environment designed for gathering, classifying, managing and accessing marine scientific literature and data, making it available for search to Operative Oceanography researchers of various institutions by means of standard protocols. The system takes as input non-textual data (measurements) and text - both published papers and documentation - and it provides an advanced search facility thanks to the rich set of metadata and, above all, to the possibility of a refined and domain targeted key-word indexing of texts using Natural Language Processing (NLP) techniques.
The paper describes the system in its details providing also evidence of evaluation.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
Share GreyLit: Using Social Media to Communicate Grey Literature
No full textThe Grey Literature Report produced by the New York Academy of Medicine supports efforts of researchers, health practitioners, and policy makers in urban and public health by curating, preserving and providing access to high quality, cutting edge research. Grey literature is continually being added to systematic reviews and evidence-based practice in the health sciences. It is also being called upon as an area of research that needs to be disseminated and communicated effectively. This research needs proven strategies to raise the profile of grey literature in order for it to be known by policy- and decision-makers. For example, at Advancing the Science to Improve Population Health conference held at the National Academies of Sciences on September 30, 2015, a presentation on Population Health Research Agenda Survey Results asks how to raise the profile of “grey literature” to be included in population health research. The AcademyHealth’s Translation and Dissemination Institute states that they are there to help "the field of health services research move its findings more effectively into policy and practice.” The Institute offered two webinars focusing on the use of Twitter in disseminating and translating evidence as way for researchers to promote and share their work. In an effort to understand dissemination of grey literature, research was conducted on the use of Twitter among health and health policy think tanks and the resulting poster, Think Tanks, Twitter, and Grey Literature (Aloia 2014), was presented at the 16th International GreyNet Conference in Washington, DC. Building on the think tanks research, this study will survey current users of The Grey Literature Report on their use of social media and how they are alerted to new grey literature in their field. Our research will add to the growing importance of grey literature to evidence-based practice and provide evidence of how best to disseminate and share research results through social media.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
Leveraging Grey Literature – Capitalizing on Value and the Return on Investment: A Cumulative Case Study
No full textLeveraging grey literature not only seeks to capitalize on its value for science and the public good, but also anticipates a return on investments in some measure. In an attempt to assess GreyNet’s return on investment in grey literature, this study identifies and reviews efforts made to leverage its own information products and services, since its relaunch in 2003.
The method of approach is a cumulative case study from 2003 onwards of a select number of information products and services provided by GreyNet. Each were introduced to serve the interests of the grey literature community and their production and supply remain sustained. The first step in
the study provides a brief description of GreyNet’s types of stakeholders and the nine selected resources intended to serve the grey literature community. Available statistics and data corresponding to the resources are also incorporated here. The second step is the design and implementation of an online survey among GreyNet stakeholders in an effort to determine their involvement. And, in the third and final step an analysis is carried out as to the observed uses of the information resources in step one with the results of the survey conducted among GreyNet stakeholders in step two.
Results from this study seek to establish an accepted level of disparity among the intended purposes, observed uses, and the involvement of stakeholders. The outcome hopes to better enable GreyNet to leverage its information resources – ensuring its positional advantage and enabling it to function more effectively.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
Library as Publisher: Convergence of New Forms and Roles of Textual and Non-Textual Grey Literature in Digital Scholarship
No full textSpecial Collections and University Archives typically constitute libraries’, an organizations’ or institutions’ treasured assets. As libraries assume greater responsibilities for the curation and preservation of resources, they also become indispensable in issuing, publishing, releasing, and making original content accessible in digital formats, while the “born digital” content grows. Managing online content creation, in addition to handling traditional textual content shifts libraries into new roles based out of necessity and costconstraints. With the dominance and reliance of electronic information now the status quo, the library’s role as publisher has become increasingly important. Hosting and creating original content in partnership with other institutional networks harnesses the collaborative power of libraries by reducing operating expenses and increasing the availability of materials to any user with an Internet connection. Although it is often thought that more non-textual resources will tend to become increasingly grey, our experience indicates the contrary. Libraries strive to make such resources less grey than originally anticipated. The increased success in finding resources or content provides better identification and classification for sources that may not have been discovered initially with little to no metadata. The impact on library collections affirms the institutional mission of teaching, research and service by celebrating and honoring the memory of historical snapshots and experiences that would be otherwise forgotten or difficult to find or document. There are many challenges in this trend including scalability and sustainability, plus financial or business models that influence levels of output and innovation. This paper will highlight examples of the convergence of textual to non-textual content by showcasing different levels of library publishing and artifact models that celebrate and include a variety of library and organizational hosted published resources on different scales. The path of convergence is intertwined but blends new publishing potential, enhanced value and best practices with outputs that are defined more through textuality and new publishing models than by hues of grey.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
Public sharing of medical advice using social media: an analysis of Twitter
No full textIntroduction: Social media tools, such as Facebook®, Twitter™, blogs and online communities, are increasingly utilized for networking and to distribute information in medicine and public health. Participation in these media has increased sharply over the past decade. Six years ago, Twitter did not exist yet now an estimated 15% of the world population subscribes to Twitter. This has created a large-scale, complex, and unindexed publicly available data source.
Goal: We sought to understand the richness and novelty of health-related Tweets by analyzing the characteristics of health information-focused tweets using automated and manual analysis.
Research methods: Utilizing the Twitter Search application programming interface (API) we retrieved two sets of English language tweets using keywords related to asthma (#asthma and asthma). Tweets were categorized by the assumed source (retweeted by a person, sent by organization, originated by an individual) and content (containing medication, symptoms, triggers, a combination, or none of these) using natural language processing. Regarding tweet source we assumed that tweets retweeted to a person (i.e., @username) were sent by an individual; those not retweeted that contained a URL were sent by an organization; and those tweets remaining were original content tweeted by an individual. Regarding content categorization, we used lexicons containing terms for asthma medication, symptoms, and five different types of asthma triggers (activities, air pollutants, allergens, environmental and irritants). In addition, we conducted content analysis using a combined text mining and manual approach. Applying association rule mining to the tweets, we generated an overview of the most frequency combination of terms presented as if-then rules. The manual, in-depth analysis evaluated a random sample of 200 tweets for originality, content, credibility and relevance.
Costs: The costs associated with this project were time to process tweets. While over 500 million tweets are generated daily, the cost of this information distribution is shared among millions of Twitter subscribers.
Results: The analysis showed that the majority of tweets contain URLS and many are retweeted. The proportion of tweets containing personal, new content is small. The majority of tweets are sent by organizations, both commercial and noncommercial, and the content are broad facts and statements. Both medication and environmental triggers are common topics.
Conclusion: The high diversity in topics and terminology combined with the small proportion of personal tweets should be taken into account when using Twitter as a resource for tracking and discovering health behaviors or problems in the population. The large proportion of tweets referring to external information may make this a very useful tool for accessing grey literature and using the tweets as descriptors. Further research is needed to create comprehensive vocabularies and methods to efficiently labels tweets.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
Analysis of National R and D Project Report Output Utilization and Economic Contribution
No full textAs the major developed countries of the world have realized the importance of open common information and its recycling, they have begun to seek a plan that will facilitate manipulation of common information. Despite development of the National R&D business and its quantitative increase in Korea, its practical use still remains at a lower level. Therefore, it is worthwhile to analyze practical use and economic contribution in order to achieve higher profits.
There are two purposes of this study. The first purpose is to draw a conclusion by analyzing/investigating the practical uses of the National R&D Reports, and the second purpose is to evaluate economic contributions by the National R&D Reports. These are possible by manipulating the improved quantitative/qualitative indicator designated to evaluate the economic contributional aspect of the National R&D Reports.
The degree of outcome measurement for the National R&D Reports was investigated through science and technology workers in both the field and the academic world. The results of this investigation show that the average time of use for the total National R&D Reports is 6.3 years and average monthly reference occurs 9.2 times. Additionally, results showed that researchers spend an average of 11.6 hours per month using the reports. Moreover, the proportion of the National R&D Reports in Collection of Science and Technology Information, the importance of the National R&D Reports in Practical Science and Technology Information, and the proportion of the National R&D Reports in Quotation Science and Technology Information are considered between 'average' and 'slightly higher than average.'
The results of the investigation/ analysis for usefulness of the National R&D Reports show that the quality of content, the quality of the system, the satisfaction, and the utility are recorded as 'slightly higher than average' and 'high.' These results demonstrate that users of the National R&D Reports consider these reports to be an important resource.
The results of the investigation/ analysis for the preservation value of the National R&D Reports indicate 83.2% positive opinion about preserving this report. Therefore, KISTI should preserve National R&D Reports at the national level.
The results of the investigation/ analysis for the demand of National R&D Reports show that the intention to use the system records falls between 'slightly higher than average' and 'high.' These results address the high number of users who intend to keep using the National R&D Reports.
The results of the investigation/ analysis for the economic contribution of the National R&D Reports show that value for practical use, value of common ownership, and contributional value— which are all qualitative indicators, respectively—fall between 'slightly higher than average' and 'high' on the scale. These results show that the users of the National R&D Reports consider it of high economic value.
The usefulness value of the National R&D Reports is 2.908won for a piece of information, and the total usefulness value of the National R&D Reports thus far is 1.713 hundred million won; the reports are estimated to hold 15.5 times the economic value over the cost. The payment value of the National R&D Reports is 2,156won for a piece of information, and the total payment value of the National R&D Reports thus far is 1,270 hundred million won; the reports are estimated to hold 11.5 times the economic value over the cost. Compared to other domestic and foreign information services’ estimation for the economic contribution—which has only recorded estimates of 3 to 9 times the value rate—the construction of these National R&D Reports is currently economically effective for businesses and is also expected to be economically feasible for businesses in the future.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
Scientific audiovisual materials and linked open data: the TIB perspective
No full textLibraries are starting to use Linked Open Data (LOD) to provide their data (library data) for reuse and to enrich them. However, most initiatives are only available for textual resources, whereas non-textual resources stay aside. Firstly, this paper discusses the potential of library data to be published as LOD. Secondly, it focuses on the library data related to the management of audiovis-ual scientific materials in the TIB|AV-Portal. The use LOD Standards to support multilingual func-tionalities and data reuse is outlined. Future developments lead to the building of semantic applica-tions based on LOD StructuresIncludes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
International identification and ‘white and grey literature’. Identities, retrieval, reuse and the certainty of knowledge while sharing and connecting information
No full textDuring the 20th century the development of identifier codes - in most cases internationally spread under ISO auspices - encouraged the idea that few things were yet “unidentifiable” and “uncontrollable” in document field. Then, the expansion of new technologies for information retrieval on the Net, made thinkable the advent of a sort of social control for documents, data and metadata identifiers: this seemed to be in conflict with the concept of a unique identification coming from an authoritative origin. In fact, we’ve seen more recently a new increase of bibliographic identifiers, mainly concerning digital environment documents, and especially, some publishing sectors not directly interested to the topic of identification have been involved in. Finally, also responsibility entities (individuals, groups, corporate bodies...) have
been included under identifying activity. The identification of publishing or documentary products/actors seems to be now consolidated. So, it becomes urgent to establish common guidelines - description, metadata, cross-identification - widely shared and implemented by agencies or any other component of the information chain. The inclusion of grey literature in meta-analysis is fundamental.
We consider the usefulness of a dynamic model for cross-sharing and cross-use of data, metadata and identifiers, that allow international agencies to pool or exchange their information collections, avoiding duplications when same data match in more than one archive. Moreover, this model could be easily supported by current techniques for information retrieval via linked data. Obviously the aim would not to create the nth super archive, but to encourage the disseminated allocation of multiple information, that could be found or summarized just when searched by users. Necessary condition is the cooperation among the agencies.
The goal of this study is showing which consequence could represent a general improvement of the public information quality level, thanks to the exponential circulation of authoritative data: “low-cost” for agencies, publicly available for everybody, and easy update according to rigorous certified criteria.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
Move beyond text – How TIB manages the digital assets researchers generate
No full textThe supply, use and significance of non-textual materials is steadily increasing in the areas of research and teaching. Digital assets like scientific videos, 3D objects and research data are highly relevant in order to make science reproducible. Yet, they often present a lack of appropriate metadata, unique identification, and long-term preservation, remaining beyond the relevant and journalbased scientific publication system. The TIB has established a competence centre for non-textual materials in order to improve the access and the use of those digital assets. As a use case of a service for scientific videos the TIB|AV-Portal is presented. Further best practices are also discussed.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
The National Portal for Recording Theses (PNST): Its Role, Importance and Constraints for Algerian Researchers
No full textIf researchers no longer face difficulties to have access to published resources which are exploding in all disciplines, they, however, make tremendous unsuccessful efforts when looking for unpublished documents (grey literature) to develop their research. For the case of theses, several researchers do not know about topics treated by their peers. Moreover, they often find constraints to get access to a specific title’s or author’s thesis. They also make a long distance, waste time and money in the attempt to reach a desired thesis. For years, this has constituted a real problem for Algerian researchers. The Research Center for Technical and Scientific Information (CERIST) in Algeria has innovated by establishing the National Portal for Recording Theses (P.N.S.T.) as a device that aims above all at caring about national scientific production in terms of theses. It is a central catalogue for registered research topics and maintained theses that provides a certain visibility of research in the country. This portal was also set up with the intention to put an end to the researchers ‘difficulties when seeking for theses.
In our paper, we have attempted to evaluate whether the researchers’ situation has known any improvement. To reach this goal, a questionnaire was administered by e.mail to a sample of researchers at the University of Constantine 2. 50 university teachers and 50 Ph.D students were concerned by this qualitative study. The analysis of the survey led to significant results that showed the positive points of this portal and the various constraints that still face researchers when attempting to explore this information gateIncludes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
