What&;#39;s in a title? Numbers of words and the presence of colons

Summary Much has been written about titles in scientific journal articles but little research has been carried out. We aimed to assess in two studies how factors like the length of a title and its structure might vary in different scientific fields, and whether or not these features have changed over time. Statistical analyses were made of 216,500 UK papers from science journals, and of 133,200 international oncology papers. Factors examined included title length, the use of colons in the titles, and the number of authors. All of these factors increased over time for both sets of papers, although there were some disciplinary differences in the findings. In both studies, titles with colons occurred more frequently with single than with multiple authors except when the numbers of co-authors were large. Certain features of titles can be related to different disciplines, different journals, the numbers of authors and their nationalities.     

Variation in informativity of titles of research papers in selected humanities journals: A comparative study

Titles constitute the most concise statement of a document's content, and are heavily used by information retrieval systems. Consequently, the great importance of titles being highly informative is indisputable. The most common measure of title ‘informativity’ has been the number of ‘substantive’ words it includes. Previous studies found significant differences between journals of different subject fields, in the sciences and the social sciences, regarding the number of substantive words in article titles. However, unlike the sciences and the social sciences, very little research has been done onhumanities journals. Examining title informativity in a group of eighteen leading English-language journals, covering various humanities disciplines, from 1940 to 1990, the present study searched for possible differences between the humanities journal and the scientific and social sciences ones, concerning patterns of title informativity. Generally, considerable differences were found in the number of substantive words in article titles between the various humanities journals checked. On the other hand, a comparison of thegroup-average means and medians of the humanities journals to group figures of journals from the sciences and the social sciences indicates significant differences for almost all decade years studied. However, titles of papers in humanities journals did follow the general trend of increase in informativity, although in a slower pace. Possible explanations of these differences are discussed and areas for further study are suggested.

Titles in English-medium Astrophysics research articles

In this study we analyse a corpus of 300 randomly selected research paper titles written in English and published between 1998 and 2012 in the most prestigious journals in the field of Astrophysics, an under-researched discipline from a linguistic standpoint. We specifically address issues related to the evolution of titles, their length, their lexical density, their type distribution and their semantic content. Our findings reveal a trend towards relatively long titles with a high lexical density, a preference for nominal and simple titles over verbal and compound ones, a very low occurrence of question constructions, and a prevalence of purpose and results over methods as key research concepts expressed in titles. We compare our findings with the results of previous studies on titles in other scientific disciplines and provide explanations for the differences and similarities observed.     

A lexical and syntactic study of research article titles in Library Science and Scientometrics

Title of a research article is an abstract of the abstract. Titles play a decisive role in convincing readers at first sight whether articles are worth reading or not. Not only do research article titles show how carefully words are chosen by authors, but also reflect disciplinary differences in terms of title words and structure between hard sciences and soft sciences. This study examined the lexical density and syntactic structure of 690 research article titles chosen from five Library Science and Scientometrics journals, aiming to reveal disciplinary differences. The result suggested both Library Science and Scientometrics have almost the same title length and the prevalent usage of Nominal Phrase (NP) to govern the title structure. The result also stated some disciplinary differences: Library Science demonstrates more punctuation complexity, particularly a greater frequency in using colons; but Scientometrics shows more involvement of words related to research methods, which is an indicator to papers’ scientific value, and more usage of declarative Full Sentence (FS) structure, which were mostly discovered in the research articles in hard sciences.

     

Relation of the title length of a journal article to the length of the article

The great importance of titles being highly informative is almost unanimously accepted in literature, assuming that the more informative titles are, the more effectively they serve their functions. The most common measure of title “informativeness” has been the number of “significant” (i.e., non-trivial) words included in it, and one of the factors which might be associated with it is the length of the paper, measured by its number of pages. The present study attempted to test, in a large group of journals from different areas and over six decades, the hypothesis that a paper with more pages will have more “significant” words in its title. Large samples of original research papers were drawn from each decade year of twenty-four leading journals selected from the sciences, the social sciences and the humanities. For each paper, the number of “significant” words in the title was correlated with the number of pages. Findings indicate a difference between the scientific journals on the one hand, and the social sciences and humanities journals on the other. A moderate positive correlation was found in most scientific journals for many periods. In the social sciences journals, and to a greater extent, in the humanities journals, a significant positive correlation was limited to only a few periods, while the rest showed a very low correlation, or even a negative one. The different findings for the sciences are perhaps attributable to their unique inherent features. This revised version was published online in August 2006 with corrections to the Cover Date.     

The effect of characteristics of title on citation rates of articles

This study aimed to assess the association between some features of articles title and number of citations in a volume of Addictive Behavior journal. All research articles published in the volume number 32 (2007) in the Addictive Behaviors journal (n = 302) were analyzed by two independent authors. For each article, the following information has been extracted: number of citations up to June 2013 in the Scopus citation database, type of and characteristics of titles, having different words in the keywords, reference to place and presence of an acronym. The summary statistics showed that mean number of citation was 16.36 ± 19.55 times. Articles with combinational title (use of a hyphen or a colon separating different ideas within a sentence) and articles with different words in the keywords (at least two different keywords) had higher number of citations. The number of citations was not correlated with the number of words in the title (r = 0.05, P = 0.325). Our results suggested that some features in the paper such as type of the title and articles with keywords different from words included in the title can help to predict the number of citation counts. These findings can be used by authors and reviewers in order to maximize the impact of articles. The length of title is not associated with citation counts. Therefore, the guide for authors of journals can be more flexible regarding the length of the title.     

Demand for Scientific Articles and Citations: An Example from the Institut de l'information scientifique et technique (France)

The patterns that appear in exchanges between researchers, scientific journal publications and the demand for scientific articles often intersect, but the logic behind each type of activity is not necessarily the same. Analyses of requests for scientific articles from document suppliers may help to interpret current developments in electronic publishing.This study of article requests to the Institut de l'information scientifique et technique (INIST) shows that, in France, document supply customers fall into three main categories: business, academic libraries and public research organisations, in descending order. Demand focuses mainly on medicine, pharmacology, biology and chemistry, and the distribution of articles is entirely in accordance with the laws of bibliometrics.A further comparative analysis shows a high reciprocal correlation (except in the physical sciences) between the 50 journals most frequently requested from INIST, and the 50 most frequently cited journals according to ISI (Institute for Scientific Information). The titles which did not appear in either one list or the other show that the most frequently cited physics journals are not necessarily requested from the document supplier, and that, conversely, some frequently requested journals are not often cited. It may therefore be assumed that a trade in electronic articles is likely to develop quite rapidly in disciplines which are common to both lists, although this would focus on reputed titles only, but that a different pattern of electronic document exchange would emerge for scientific literature in other disciplines.     

Assessing the usefulness of bibliometric indicators for the humanities and the social and beha vioural sciences: A comparative study

An evaluation was made of the use of bibliometric indicators for five disciplines in the humanities (social history, general linguistics, general literature, Dutch literature, and Dutch language) and three disciplines in the social and behavioural sciences (experimental psychology, anthropology, and public administration) in the Netherlands. Articles in journals were the predominant outlet in all disciplines. Monographs and popularizing articles were more important outlets in softer fields than in harder ones. The enlightenment function of scholarship was especially evident in Dutch literature and language, and public administration. Only some of the humanities disciplines are locally oriented. Although many publications were written in English, only experimental psychology, general linguistics, anthropology, and genrral literature were internationally oriented regarding output media. The impact of departments differed greatly both within and between disciplines. For all disciplines, bibliometric indicators are potentially useful for monitoring international impact, as expert interviews confirmed. Especially in Dutch language, Dutch literature and public administration, ISI-citation data are not very useful for monitoring national impact.     

A structural topic model approach to scientific reorientation of economics and chemistry after German reunification

The detection of differences or similarities in large numbers of scientific publications is an open problem in scientometric research. In this paper we therefore develop and apply a machine learning approach based on structural topic modelling in combination with cosine similarity and a linear regression framework in order to identify differences in dissertation titles written at East and West German universities before and after German reunification. German reunification and its surrounding time period is used because it provides a structure with both minor and major differences in research topics that could be detected by our approach. Our dataset is based on dissertation titles in economics and business administration and chemistry from 1980 to 2010. We use university affiliation and year of the dissertation to train a structural topic model and then test the model on a set of unseen dissertation titles. Subsequently, we compare the resulting topic distribution of each title to every other title with cosine similarity. The cosine similarities and the regional and temporal origin of the dissertation titles they come from are then used in a linear regression approach. Our results on research topics in economics and business administration suggest substantial differences between East and West Germany before the reunification and a rapid conformation thereafter. In chemistry we observe minor differences between East and West before the reunification and a slightly increased similarity thereafter.

     

Use of bibliographic data bases for scientometric studies

The paper is a review of different applications of various bibliographic data bases to bibliometric and scientometric research such as identifying the leading journals in certain fields, investigating the structure and development of particular fields including trend analysis and forecasting, as well as the study of the contribution of various countries to world science as reflected in scientific literature presented in information files. The paper also covers the results of investigation of Polish scientific literature, as presented in the foreign data bases, in the fields of information science (LISA, ISA, INSPEC, 1977–1983), chemistry (CASearch, 1978–1985), physics (INSPEC, 1979–1985), science-various disciplines (SCISEARCH, 1980–1984). Along with many advantages of using bibliographic data bases for scientometric research some limitations are also described which may originate in data bases content, and have to be taken into account while designing such a type of investigation.     

A bibliometric analysis and comparison on three information science journals: JASIST,IPM, JOD, 1998–2008

Employing a citation analysis, this study explored and compared the bibliometric characteristics and the subject relationship with other disciplines of and among the three leading information science journals, Journal of the American Society for Information Science and Technology (JASIST), Information Processing and Management and Journal of Documentation. The citation data were drawn from references of each article of the three journals during 1998 and 2008. The Ulrich’s Periodical Directory, Library of Congress Subject Heading, retrieved from the WorldCat, and LISA database were used to identify the main class, subclass and subject of cited journals and books. Quantitative results on the number of JASIST, IPM and JOD literature references, average number of references cited per paper, document type of cited literature and the journal self-citation rate are reported. Moreover, the highly cited journals and books, the main classes and subclasses of cited journals and books in papers of the three journals, the highly cited subjects in journals and books of library and information science were identified and analyzed. Comparison on the characteristics of cited journals and books confirmed that all the three journals under study are information science oriented, except JOD which is library science orientation. JASIST and IPM are very much in common and diffuse to other disciplines more deeply than JOD.     

A comparative study of interdisciplinary changes between information science and library science

This study employs the method of direct citation to analyze and compare the interdisciplinary characteristics of the two disciplines of library science and information science during the period of 1978–2007. Based on the research generated by five library science journals and five information science journals, library science researchers tend to cite publications from library and information science (LIS), education, business/management, sociology, and psychology, while researchers of information science tend to cite more publications from LIS, general science, computer science, technology, and medicine. This means that the disciplines with larger contributions to library science are almost entirely different from those contributing to information science. In addition, researchers of library science frequently cite publications from LIS; the rate is as high as 65.61%, which is much higher than the rate for information science, 49.50%. However, a decreasing trend in the percentage of LIS in library science indicates that library science researchers tend to cite more publications from non-LIS disciplines. A rising trend in the proportion of references to education sources is reported for library science articles, while a rising trend in the proportion of references to computer science sources has been found for information science articles. In addition, this study applies an interdisciplinary indicator, Brillouin’s Index, to measurement of the degree of interdisciplinarity. The results confirm that the trend toward interdisciplinarity in both information science and library science has risen over the years, although the degree of interdisciplinarity in information science is higher than that in library science.     

LIS journals scientific impact and subject categorization: a comparison between Web of Science and Scopus

The study compares the coverage, ranking, impact and subject categorization of Library and Information Science journals, specifically, 79 titles based on data from Web of Science (WoS) and 128 titles from Scopus. Comparisons were made based on prestige factor scores reported in 2010 Journal Citation Reports and SCImago Journal Rank 2010 and noting the change in ranking when the differences are calculated. The rank normalized impact factor and the Library of Congress Classification System were used to compare impact rankings and subject categorization. There was high degree of similarity in rank normalized impact factor of titles in both WoS and Scopus databases. The searches found 162 journals, with 45 journals appearing in both databases. The rankings obtained for normalized impact scores confirm higher impact scores for titles covered in Scopus because of its larger coverage of titles. There was mismatch of subject categorization among 34 journal titles in both databases and 22 of the titles were not classified under Z subject headings in the Library of Congress catalogue. The results revealed the changes in journal title rankings when normalized, and the categorization of some journal titles in these databases might be incorrect.     

Bradford's Law in the Context of Information Provision

The aim of the study is to study empirical use of Bradford's law for decisions concerning information systems in problem based fields, were journals from different disciplines cover relevant information. Results of comparison of the cores in different fields can be used as a base for tailoring an information system. Bradford's law is in the study applied on five databases in the topic "Information retrieval and seeking" in order to compare the size and titles of the core journals. These databases give different views of the same interdisciplinary topic. Problems are relevance judgments, which change the shape of the graphs, and consistency of concepts in the analysis. The results show that Bradford analyses can be useful tools in developing information systems.     

Authorship patterns in theory based versus research based journals

This article examines authorship pattern in two theory based journals, one American and one Canadian. Data were collected on the number of single, double, and multiple authors from 1955 to 1994 inEducational Theory and from 1970 to 1994 in theJournal of Educational Thought. The years were, in turn, divided into eight and five five-year intervals respectively. Frequencies and percentages were generated for each interval and chi-squares were computed between intervals and overall. In addition, author/article ratios were calculated for each year forEducational Theory. Results revealed that the majority of authorships were single in both journals regardless of the date of publication. These findings further challenge de Solla Price's predictions that co-and multiple authorships would eventually outnumber single authorships. The failure to distinguish between journal type and to allow for discrepancies within disciplines raises new concerns about conclusions drawn, to date, in the literature.     

Identifying economics’ place amongst academic disciplines: a science or a social science?

Different academic disciplines exhibit different styles, including styles in journal titles. Using data from the 2014 Research Excellence Framework (REF) in the UK we are able to identify the stylistic trends of different disciplines using 155,552 journal titles across all disciplines. Cluster analysis is then used to group the different disciplines together. The resulting identification fits the social sciences, the sciences and the arts and humanities reasonably well. Economics overall, fits best with philosophy, but the linkage is weak. When we divided economics into papers published in theory, econometrics and the remaining journals, the first two link with mathematics and computer science, particularly econometrics, and thence the sciences. The rest of economics then links with business and thence the social sciences.     

Global knowledge management research: A bibliometric analysis

The present study characterizes the dynamic publication activity of global knowledge management (KM) by data collected through a search restricted to articles in ISI Web of Science.A total of 2727 unique authors had contributed 1407 publications since 1975. The overwhelming majority (2349 or 86%) of them wrote one publication. The productive authors, their contribution and authorship position are listed to indicate their productivity and degree of involvement in their research publications. The sum of research output of the first or responsible authors from USA, UK and Germany reaches 57% of the total productivity. The distribution of articles is rather widespread - they published in 462 titles of serials, spanning 110 Journal Citation Reports subject categories. The higher quality journals make publication of findings more visible. A Pearson's correlation coefficient is statistically found to be significant between citation frequency of article and impact factor of journal, instead of authorship pattern. The results also indicate that R&D expenditures were actually not proportional to research productivity or citation counts. As the subject highly interacts with other disciplines, the field of KM has not yet developed its own body of literature. KM might have been evolving an interdisciplinary theory that is developing at the boundaries of scientific disciplines. This revised version was published online in June 2006 with corrections to the Cover Date.     

Relation of title length of journal articles to number of authors

The great importance of titles being highly informative is almost unanimously accepted in literature, assuming that the more informative titles are, the more effectively they serve their functions. The most common measure of title informativeness has been the number of substantive words included in it, and one of the factors which might be associated with it is the number of authors. The present study attempted to test, in a large group of journals fromdifferent areas, and over six decades, the hypothesis that a paper signed by a larger number of authors will have more substantive words in its title. Large samples of original research papers were drawn from each decade year of fourteen leading journals. For each paper, the number of substantive words in the title was correlated with the number of authors. Findings indicate a difference between the scientific journals on the one hand, and the social sciences and humanities journals on the other. A moderate positive correlation was found in most scientific journals (excluding mathematics) for many periods. In the social sciences journals, and to a greater extent, in the humanities journals, a significant positive correlation was limited to only a few periods, while the rest showed a very low correlation, or even a negative correlation. The different findings for the sciences may be somehow associated with their higher rate of multiple authorship.Paper presented at the Fourth International Conference on Bibliometrics, Informetrics and Scientometrics in Berlin (Germany), September 11–15, 1993.
