Development of intelligent system of global bibliographic search

The paper presents scientifically grounded principles of formation and algorithms of a global bibliographic retrieval system based on modern intelligent technologies (intelligent linguistic analysis of texts and database management) and Internet search methods. Within the framework of theoretical bibliography, for the first time taking into account the specifics of modern intelligent software, a new algorithm of an integrated automated system for global bibliographic retrieval as well as search for specialized publications to publish research papers was developed. The developed methods include the formation of a normalized database of keywords based on the Universal Decimal Classification (UDC) categories and the automatic assignment of keywords from this normalized database to research papers by an intelligent system for linguistic analysis of texts. The proposed use of keywords as data labels in the form of UDC categories, covering all branches of knowledge, makes it possible to precisely label and describe research papers and scientific publications (journals, proceedings of scientific conferences) to the fullest extent possible. The search for research papers by the proposed bibliographic retrieval system as well as the search for specialized publications to publish those research papers is carried out automatically by normalized keywords assigned to research papers and scientific journals based on intelligent linguistic analysis of the content of those research papers. The study makes a social contribution and shows how it is important to create and utilize best practices, processes and strategies of bibliographic retrieval, which are essential in the development of science in modern society. Besides, in social terms, the search for bibliographic information is one of the methods to solve the problem of finding a relation between personal and public knowledge. The implementation of the study results in accordance with the presented algorithms consists in designing a special global public Internet search resource.

Radiofrequency Technologies of Local Positioning in Healthcare

Introduction. Localization of objects position in closed space plays an important role in many areas of human activity, including medicine. Using indoor-positioning technologies as a part of telemedicine systems allows one to improve the quality of medical care and to reduce mortality of patients. Therefore, indoor-positioning technologies contribute to achieve the goals outlined in the Russian Federation government`s program "Healthcare development". Aim. To study the applicability of modern radiofrequency technologies for localization of patients inside a hospital building. Materials and methods. Scientific sources devoted to indoor-positioning based on radiofrequency technologies were analyzed. The methods used included: - bibliographic retrieval; - selection and verification of sources based on their relevance; - analysis of sources by methods of deconstruction and comparative analysis . Results. The result of the analysis indicated that radiofrequency positioning technologies allow one to locate objects using radio waves properties. The disadvantage of the technology is the penetration of radio signal through walls and floors. Given this, it is necessary to use complex algorithms to detect an object with accuracy to a specific room. Despite this disadvantage, radiofrequency technologies can be used for positioning in medical facilities since they are easy in deployment and service. Also, they are used in ready-made commercial solutions. ZigBee technology is an exception because it does not allow one to track moving objects in real-time. Conclusion. Based on the study it was concluded that BLE technology is the most suitable for indoor-positioning in medical facilities. It is energy-efficient, it has sufficiently fast data transfer rate, good communication radius and a large range of ready-made communication equipment. It is also worth noting that most wireless medical sensors exchange data via the BLE interface.

Circulating lncRNAs as noninvasive biomarkers in bladder cancer: A diagnostic meta-analysis based on 15 published articles.

Owing to inconsistency between reports, a meta-analysis was designed to appraise the clinical implications of long non-coding RNAs (lncRNAs) in urine and blood for the diagnosis of bladder cancer. Studies that met the criteria were acquired by bibliographic retrieval through PubMed, Embase, and the Cochrane Library. The pooled diagnostic performance was evaluated by calculating the area under the summary receiver operator characteristic (SROC) curve. The potential sources of heterogeneity were approached through meta-regression and subgroup analyses. All statistical analyses and plots were performed by RevMan 5.3, Meta-DiSc 1.4, and STATA 12.0. A total of 43 studies from 15 articles consisting of 3370 bladder cancer patients and 3212 controls were incorporated in our meta-analysis. lncRNAs in urine and blood performed relatively well in diagnosing bladder cancer, with a pooled sensitivity of 0.78, a specificity of 0.79, and an area under the SROC curve (AUC) of 0.86. H19 displayed the best diagnostic accuracy with a pooled AUC of 0.90, followed by UCA1 and MALAT1. The heterogeneity among studies was partly conducted by sample size, lncRNA existence form (cell-free or intracellular lncRNA), lncRNA origin (exosome- or non-exosome-based lncRNA), lncRNA profiling (single- or multiple-lncRNA), specimen types, and ethnicity. lncRNAs in urine and blood may serve as noninvasive diagnostic biomarkers with great promise for bladder cancer, while their clinical values need to be examined through further synthetic forward-looking studies.

Searching bibliographic data using graphs: A visual graph query interface

Abstract With the ever-increasing scientific literature, improving the efficiency of searching bibliographic data has become an important issue. With a lack of support of current bibliographic information retrieval systems in expressing complicated information needs, getting relevant bibliographic data is a demanding task. In this paper, we propose a visual graph query interface for bibliographic information retrieval. Through this interface, users can formulate bibliographic queries by interacting with a graph. Visual graph queries use a set of nodes with constraints and links among nodes to represent explicit and precise bibliographic information needs. The proposed visual graph query interface allows users to formulate several complex bibliographic queries (e.g., bibliographic coupling) that are not attainable in current major bibliographic information retrieval systems. In addition, the proposed interface requires less number of queries in completing everyday bibliographic search tasks.

Cognitive Styles, Demographic Attributes, Task Performance, and Affective Experiences: An Empirical Investigation into Astrophysics Data System (ADS) Core Users

As a primary digital library portal for astrophysics researchers, SAO/NASA ADS (Astrophysics Data System) 2.0 interface features several visualization tools such as Author Network and Metrics. This research study involves 20 ADS long term users who participated in a usability and eye tracking research session. Participants first completed a cognitive test, and then performed five tasks in ADS 2.0 where they explored its multiple visualization tools. Results show that over half of the participants were Imagers and half of the participants were Analytic. Cognitive styles were found to have significant impacts on several efficiency-based measures. Analytic-oriented participants were observed to spent shorter time on web pages and apps, made fewer web page changes than less-Analytic-driving participants in performing common tasks, whereas AI (Analytic-Imagery) participants also completed their five tasks faster than non-AI participants. Meanwhile, self-identified Imagery participants were found to be more efficient in their task completion through multiple measures including total time on task, number of mouse clicks, and number of query revisions made. Imagery scores were negatively associated with frequency of confusion and the observed counts of being surprised. Compared to those who did not claimed to be a visual person, self-identified Imagery participants were observed to have significantly less frequency in frustration and hesitation during their task performance. Both demographic variables and past user experiences were found to correlate with task performance; query revision also correlated with multiple time-based measurements. Considered as an indicator of efficiency, query revisions were found to correlate negatively with the rate of complete with ease, and positively with several time-based efficiency measures, rate of complete with some difficulty, and the frequency of frustration. These results provide rich insights into the cognitive styles of ADS’ core users, the impact of such styles and demographic attributes on their task performance their affective and cognitive experiences, and their interaction behaviors while using the visualization component of ADS 2.0, and would subsequently contribute to the design of bibliographic retrieval systems for scientists.

Genetics and epigenetics of schizophrenia

Schizophrenia is a severe psychiatric disorder with an estimate prevalence of 0.3-0.7%. Studies on family aggregation showed a higher incidence of disease among family members of affected people. This observation lead to formulate the hypothesis that schizophrenia could be inheritable, but twin studies have shown a concordance of disease between monozygotic twins only of 50%, indicating the concomitant role of environmental factors in the pathogenesis of schizophrenia. Researches in molecular biology field have allowed the identification of genes that confer susceptibility to schizophrenia on chromosomes 1, 2, 3, 5, 6, 8, 10, 11, 13, 14, 20 and 22. Epigenetic modifications of gene expression, that not involve the primary DNA sequence, may also predispose to schizophrenia, in particular the methylation of genes involved in neurotransmission (RELN, GAD1, MARLIN-1, and NR3B GRIA2, VGLUT1 and 2, 5HT2a, COMT and BDNF), the histone modifications and the action of non-coding RNAs. This review deals with the results of a bibliographic retrieval on PubMed, carried out, using the key words: schizophrenia, genetics, epigenetics. From the epitomized results it can be derived that schizophrenia seems to be a multifactorial disease. Environmental factors, that can cause epigenetic modifications, are important in its pathogenesis, acting on a biological inheritable vulnerability.

Benchmarking Study of the Global and Ukrainian Trends in Nanotechnologies’ Scientific Research for the Future NBIC-Society

Aims: In the conditions of advanced countries industrial markets’ competition escalation the issue of creating new economy on the basis of nanotechnologies as Nano-bio-info and cogno(NBIC)technologies is becoming more and more important. As all developed countries, Ukraine conducts fundamental and applied research in the field of nanotechnologies, and the research priorities to be agreed with solving both global and specific national problems in view of building-up a modern NBIC-civilization. Short Research Article Kyzym et al.; BJEMT, 13(2): 1-24, 2016; Article no.BJEMT.24812 2 The main purpose of the research is to analyze the modern perspectives and to perform benchmarking study of the Global and Ukrainian trends in nanotechnologies development as part of NBIC-technologies’ scientific domain to identify priority areas of scientific and technical policy of Ukraine. Study Design: The reviews were carried out in the period 2010–14 on the basis of studying the world countries nanotechnologies development trends as well as on the basis of the research results obtained by Ukrainian academic institutions. Place and Duration of Study: Scientific Research Center for Industrial Development Problems of the National Academy of Science of Ukraine, Department of Foreign Economic Relations and Touristic Business of V.N. Karazin Kharkiv National University conducted the research between January 2014 and December 2015. Methodology: Content analysis and bibliographic retrieval have been used as the main methods of research, which allowed making a meaningful analysis of classic papers and researches of modern economists-practitioners devoted to the peculiarities of the Global and Ukrainian trends in NBICcivilization emergence. Models of time series, including also trend analysis, were used for forecasting. Computations were performed in Application Software Package “Statistica 8”. Results: The article demonstrates main practical results of various economic sectors development achieved through implementing comprehensive scientific-technical programs to develop nanotechnologies during 2010–2014 in Ukraine. Benchmarking analysis of the researchers’ publishing activity in the field of nanotechnology in the leading world countries and in Ukraine has shown that in general, the dynamics of research in Ukraine correspond to the global trends, but is much slower. Development of nanomaterials, nanobiotechnology and nanoelectronics are the main fields of nanoscience research. Nanomedicine & nanobiology are specific features of Ukrainian research field that allows us to consider those areas to have competitive advantages of nanotechnology development in Ukraine. At the same time a very small number of publications in the field of nano-electronics and nano-energy engineering testifies of a substantial lagging behind the main global trends. The low level of patenting in nanotechnology development in Ukraine satates the need, on the one hand, to stimulate applied research, and on the other hand, to improve procedures for obtaining intellectual property rights protection. Conclusion: The priorities of Ukrainian nanotrechnology studies, as part of NBIC-technologies’ scientific domain, need to be clarified in accordance with the global problems to be solved by any country and in accordance with the existing potential and possibilities of nanotechnology research as regards the emergence of NBIC-society. In order not to lose the existing potential in the field of nanoelectronics and nano-energy engineering the government should support the local development, especially at the stage of basic research. Institutional support to the interaction of science and business is required at the stage of applied research. Consequently, to revitalize hightech engineering, the developments in the field of nanoelectronics should become a priority for the government support. Lack of international patents in Ukraine speaks of the need to ensure more active cooperation between Ukrainian, European and international patent organizations, particlualry under the Patent Cooperation Treaty.

A study on the user evaluation for an RDA-based Korean bibliography retrieval system

Purpose– The purpose of this paper is to validate the usefulness of resource description and access (RDA) from user perspectives by implementing an RDA-based bibliographic retrieval system, and comparing it against two retrieval systems.Design/methodology/approach– Surveys and interviews were conducted to gather responses from 20 subjects who used the systems. Usability was measured according to the following metrics: search usefulness from search process and results; search efficiency, measured in time and the number of steps involved; general satisfaction for search results and process, and for information need; satisfaction for search functionalities, with five sub-measures (usability of functions of search tool, appropriateness of search results, usability of additional information, usability of associative relations, and appropriateness of search categories); and system convenience in terms of understandability and ease.Findings– The survey results indicate that all but the satisfaction for appropriateness of search categories showed significant differences between the systems. The interviews show that the RDA system received from the subjects a more positive evaluation compared to the counterpart systems, in search usefulness, search efficiency, general search satisfaction, satisfaction for search functionalities.Practical implications– Though a few organizations such as the Library of Congress in the USA have implemented RDA, no such endeavors have been undertaken in the context of Korean bibliography, and especially for the systematic validation of usability of such a system from user perspectives.Originality/value– This is the first published study that validates the usefulness perceived by users of RDA in the context of Korean bibliography.

Bibliographic families in COBIB

ABSTRACTThe article deals with bibliographic families in the COBIB online catalogue, their size and complexity. Using a random sample of bibliographic records, relationships among family members are also treated. Bibliographic relationships in the catalogue are not always identified or are expressed only implicitly, therefore data on relationships should be added and the corresponding bibliographic records linked. This would make searching among the different versions of the same item easier, bibliographic retrieval would be improved and the use of library materials made more efficient.

Semantic information retrieval research based on co-occurrence analysis

Purpose – The paper aims to develop a new method for potential relations retrieval. It aims to find common aspects between co-occurrence analysis and ontology to build a model of semantic information retrieval based on co-occurrence analysis. Design/methodology/approach – This paper used a literature review, co-occurrence analysis, ontology build and other methods to design a model and process of semantic information retrieval based on co-occurrence analysis. Archaeological data from Wuhan University Library's bibliographic retrieval systems was used for experimental analysis. Findings – The literature review found that semantic information retrieval research mainly concentrates on ontology-based query techniques, semantic annotation and semantic relation retrieval. Moreover most recent systems can only achieve obvious relations retrieval. Ontology and co-occurrence analysis have strong similarities in theoretical ideas, data types, expressions, and applications. Research limitations/implications – The experiment data came from a Chinese university which perhaps limits its usefulness elsewhere. Practical implications – This paper constructed a model to understand potential relations retrieval. An experiment proved the feasibility of co-occurrence analysis used in semantic information retrieval. Compared with traditional retrieval, semantic information retrieval based on co-occurrence analysis is more user-friendly. Originality/value – This study is one of the first to combine co-occurrence analysis with semantic information retrieval to find detailed relationships.

Parents of Invention: The Development of Library Automation Systems in the Late 20th Century

Prior to his death in 2012, Christopher Brown-Syed was the editor of the journal, Library and Archival Security, and taught at Seneca College, Toronto, Ontario, Canada. Earlier in his career, he was an employee of the library automation vendors, Plessey and Geac. Parents of Invention is a collection of memoirs and reflections on the developments in library automation from the late 1970s through the middle 1990s, from the viewpoint of employees of vendors and libraries at the time. Parents of Invention gives insight into the development of integrated library systems during this period, which saw the revolution of circulation and catalog functions in libraries. Brown-Syed writes from a Canadian perspective, and many of the contributors to the book are from Canada, Great Britain, and Australia. Brown-Syed is cognizant of US libraries and vendors, and refers to US examples and experiences on occasion. The author interviewed fifteen individuals via phone and email while researching this book. A closing chapter contributed by Louise O'Neill of McGill University, Canada, addresses future trends for automation in libraries. Online bibliographic retrieval systems for literature searching are briefly discussed, but readers of a certain age will notice some of the facts are wrong. Ovid, a well-known bibliographic database vendor, is rightly credited with revolutionizing online searching through end-user access to its CD-ROM products in biomedical libraries. Ovid's publication of the National Library of Medicine's MEDLINE to CD-ROM kept many librarians busy during this period with changing discs and watching for overheating of CD-ROM towers. However, Brown-Syed does not use the correct company name for the period discussed, which was CD Plus Technologies, a name that Ovid carried from its founding through the early 1990s. CD Plus did not change its name to Ovid until the late 1990s, when client-server and Internet technology made access to online journal articles possible. Also, typographical errors are noticeable throughout the book. American readers may be distracted by British spellings, abbreviation conventions, and world view. Still, the book is a valuable contribution to documenting the challenges that the parents of invention were faced with while working together to implement new technologies to improve library operations. This book is recommended for library and information science students, and anyone interested in reading histories of library automation and librarian memoirs.

Modelling Information Retrieval in an Object-Oriented Database Environment

From the 1994 CAIS Conference: The Information Industry in Transition McGill University, Montreal, Quebec. May 25 - 27, 1994.Bibliographic or full text information retrieval (IR) applications have been implemented either as special purpose programs or as systems based on database technology. The relational model has been used with some success but most work has used separate IR specific models. The object-oriented data model offers many advantages by incorporating documents as complex objects. Basic concepts such as objects, class hierarchy, inheritance, aggregation, collections and methods are applied to the IR situation. Various approaches to query processing are introduced. To illustrate these concepts a partial implementation in object-Pascal is presented. Problems of standardization and formalization are discussed.

Comparison of Contributing Factors in System Affective Response in a Boolean and Hypertext Bibliographic Database Environment

The present study compares factors of searcher affective response to two bibliographic retrieval systems. One system relied on hypertext linking to facilitate searching, the other a traditional Boolean approach. Eighty-five participants were randomly assigned to either system to perform four search tasks. Data collected from study participants were analyzed using factor analysis. . .

A retrospective cohort study of structured abstracts in MEDLINE, 1992–2006

Structured abstracts contain distinct labeled sections (e.g., “RESULTS”). The MEDLINE/PubMed database incorporates English-language abstracts that appear in the journals that the US National Library of Medicine (NLM) indexes. If English-language structured abstracts appear in a journal that is indexed, the labels in these abstracts usually appear in all uppercase letters, generally followed by a colon, in MEDLINE/PubMed citations [1]. Several years after formats for more informative abstracts were proposed [2–,5], NLM studied the structured abstracts that appeared in MEDLINE from 1989–1991 as an initial step in exploring their utility in enhancing bibliographic retrieval [6]. This early study showed that structured abstracts were an emerging, but rapidly growing phenomenon; that MEDLINE records with structured abstracts tended to have more access points (Medical Subject Headings [MeSH] terms and text words) than MEDLINE records as a whole; and that there was significant variation in the structured abstract formats that different journals prescribed. Implementation of structured abstracts by biomedical journals has been examined on a small scale in the clinical medicine domain [7, 8], but no large-scale examination across all of MEDLINE has occurred since the first exploratory study by NLM. Hence, the objective of this study was to conduct a retrospective cohort study to measure and characterize the growth in structured abstracts in MEDLINE since 1991, with a view, again, toward exploring their utility in enhancing information display and retrieval.

OBIRE

It has been widely recognized that bibliographic information plays an increasingly important role for scientific research. Peer-to-peer (P2P) networks provide an effective environment for people belonging to a community to share various resources on the Internet. This paper presents OBIRE, an ontology based P2P network for bibliographic information retrieval. For a user query, OBIRE computes the degree of matches to indicate the similarity of a published record to the query. When searching for information, users can incorporate their domain knowledge into their queries which guides OBIRE to discover the bibliographic records that are of most interest of users. In addition, fuzzy logic based user recommendations are used to compute the trustiness of a set of keywords used by a bibliographic record which assists users in selecting bibliographic records. OBIRE is evaluated from the aspects of precision and recall, and experimental results show the effectiveness of OBIRE in bibliographic information retrieval.

Vocabularies and Retrieval Tools in Biomedicine: Disentangling the Terminological Knot

Terms like "thesaurus", "taxonomy", "classification", "glossary", "ontology" and "controlled vocabulary" can be used in diverse contexts, causing confusion and vagueness about their denotation. Is a thesaurus a tool to enrich a writer's style or an indexing tool used in bibliographic retrieval? Or can it be both? A literature study was to clear the confusion, but rather than giving us consensus definitions, it provided us with conflicting descriptions. We classified these definitions into three domains: linguistics, knowledge management and bibliographic retrieval. The scope of the terms is therefore highly dependent on the context. We propose one definition per term, per context. In addition to this intra-conceptual confusion, there is also inter-conceptual vagueness. This leads to the introduction of misnomers, like "ontology" in the Gene Ontology. We examined some important (bio)medical systems for their compatibility with the definitions proposed in the first part of this paper. To conclude, an overview of these systems and their classification into the three domains is given.

Development of Similar Bibliographic Retrieval System based on Neighboring Words and Keyword Topic Information

Development of Similar Bibliographic Retrieval System based on Neighboring Words and Keyword Topic Information

The development of the Medical Literature Analysis and Retrieval System (MEDLARS).

The research provides a chronology of the US National Library of Medicine's (NLM's) contribution to access to the world's biomedical literature through its computerization of biomedical indexes, particularly the Medical Literature Analysis and Retrieval System (MEDLARS). Using material gathered from NLM's archives and from personal interviews with people associated with developing MEDLARS and its associated systems, the author discusses key events in the history of MEDLARS. From the development of the early mechanized bibliographic retrieval systems of the 1940s and to the beginnings of online, interactive computerized bibliographic search systems of the early 1970s chronicled here, NLM's contributions to automation and bibliographic retrieval have been extensive. As NLM's technological experience and expertise grew, innovative bibliographic storage and retrieval systems emerged. NLM's accomplishments regarding MEDLARS were cutting edge, placing the library at the forefront of incorporating mechanization and technologies into medical information systems.
