The document discusses bibliometrics and bibliometric laws. It defines bibliometrics as the application of mathematical and statistical methods to bibliographic information, and discusses its origins and objectives. Three important bibliometric laws are covered: Lotka's law describes the frequency of publication by authors, Bradford's law explains the scattering of articles across journals, and Zipf's law concerns the frequency of word usage. In conclusion, bibliometrics is an important tool in library and information science for studying information processes and flows.

Bibliometrics literally means "book measurement" but the term is used about all kinds of documents (with journal articles as the dominant kind of document).
What is measured are not the physical properties of documents but statistical patterns in variables such as authorship, sources, subjects, geographical origins, and citations.

under the umbrella of informatics/information science. Bibliometrics has been used for almost a century
as a descriptive and evaluative science.1
The term “bibliometrics” was coined by Alan Pritchard in 1969.
Prior to this, the field had been labeled “statistical bibliography” by British librarian E. Wyndham Hulme in
1922

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

3. Introduction to the term "Bibliometrics”
Origin of the term “Bibliometrics”
Biblio + Metrics = Bibliometrics
“Biblio” is originated from Greek word
“Biblion” which means “Book” or “Paper”
“Metrics” is originated from Greek or Latin
word “Metricus” or “Metrikos” which
means the science of Meter or to measure

4. Continued 1….
Bibliometrics is a set of methods used to study
or measure texts and information. Citation
analysis and content analysis are commonly
used in Bibliometrics methods. While
Bibliometrics methods are most often used in
the field of library and information science.
Bibliometrics uses mathematical and statistical
methods to analyse and measure the output of
publications. Modern Bibliometrics has been
largely inspired by Derek de Solla Price and the
seminal work was carried out by him in the
middle of the last century.
5. Origin Of the term Bibliometrics
The term “Bibliometrics” by Pritchard and
“Scientometrics” by Nalimov and
Mulchenko have been introduced almost
simultaneously in 1969. While Pritchard
explained the term Bibliometrics as "the
application of mathematical and statistical
methods to Bibliographic information of
books and other media of communication”.
Continued ….
6. Nalimov and Mulchenko defined
Scientometrics as "the application of those
quantitative methods which are dealing
with the analysis of science viewed as an
information process" (Nalimov and
Mulchenko, 1969). According to these
interpretations, Scientometrics is restricted
to the measurement of science
communication, whereas Bibliometrics is
designed to deal with more general
information processes.

7. Definitions
According to Potter :- “The Study and
measurement of Publication patterns of all forms
of written communication and their authorship”.
According to Alan Pritchard :- “Studies which
seek to quantify the process of written
communication”.
According to Alvin M. Schrader :- “Scientific
study of recorded discourses”.

11. Why Bibliometrics
To identify which areas are most active and
which are becoming important.
Identify the influences & “cross fertilizations”.
Useful to the policy makers who are deciding
the priority areas in a certain research domain.
12. Applications of Bibliometrics
To identify research trends and growth of
knowledge.
To estimate comprehensiveness of secondary
periodicals.
Library selection, weeding, policies Information
organization Information management.
To identify users of different subjects.
To identify authorship and its trends in documents
on various subjects.
To forecast past, present and future publishing
trends.
To predict productivity of publishers, individual
authors, organizations and countries.
14. Lotka’s Law (1926)
The Frequency Distribution of
Scientific Productivity
“It would be of interest to determine, if
possible, the part which men of different
caliber contribute to the progress of science
considering first simple volume of
production.
Alfred J. Lotka.
15. Lotka’s law: xn • y = C
Xnœ1/y
xn = c1/y
C=xn y
The total number of authors y in a given subject,
each producing x publications, is inversely
proportional to some exponential function n of x.
Where:
x = number of publications
y = no. of authors credited with x
publications
n = constant (equals 2 for
scientific subjects)
C = constant
inverse square law of scientific productivity
16. Lotka’s Law
The number of authors making n
contributions to the literature is about
1/n2 of those making one
– 60% of authors make one contribution
– 15% of authors make two contributions
– <7% of authors make three contributions
– <4% of authors make four contributions
– <2.5% of authors make five contributions
– 1.25% of authors make six contributions
– <1% of authors make seven contributions
17. Lotka’s Law Example :
Out of 1000 authors
– 608 publish 1 article
– 152 publish 2 articles
– 68 publish 3 articles
– 38 publish 4 articles
– 24 publish 5 articles
– 17 publish 6 articles
– 12 publish 7 articles
Not exact prediction but holds true
overall in most fields
18. Bradford’s Law (1934)
"If scientific journals are arranged in order
of decreasing productivity of articles on a
given subject, they may be divided into a
nucleus of periodicals more particularly
devoted to the subject and several groups
or zones containing the same number of
articles as the nucleus, when the numbers
of periodicals in the nucleus and
succeeding zones will be as n : n2 : n3.
Samual.Climent Bradford
20. Bradford’s Law of Scattering
In any field of interest, relevant journals
can be split into three groups
Each group contributes the same number
of relevant articles to citations in the field
# of 1st group journals = k
3 sources = 130 articles
# of 2nd group journals = k*n
9 sources = 130 articles
# of 3rd group journals = k*n2
27 sources = 130 articles
23. Zipf’s Law of term distribution
In a document of ca. 10,000 words the
most frequently used word is “the” at 950
Times.
the 2nd most frequently used word is “a”
at 490 Times.
the 3rd most frequently used term is “in”
at 340 Times.
the 1000th most frequently used term is
“fruit” at 1 time.
24. Zipf’s Law of term distribution
Frequency x occurrences = constant
1 x 950 = 950
2 x 490 = 980
3 x 340 = 1020
1000 x 1 = 1000
Constant = 1000 for this document
25. Conclusion
As conclusion we can say that, Bibliometrics is a major
sub-discipline of quantitative research. This is a tool used by
the library and information science professionals for studying
the communication processes, information flows, and for
better understanding and effective management and
dissemination of information. Bibliometrics techniques are
being used for a variety of purposes like determination of
various scientific indicators, valuation of scientific output,
selection of journals for libraries and even forecasting the
potential of a particular field.

26. Continued 1….
It is effective for, measuring the scattering of
articles on a subject in various periodicals (Bradford),
measuring the productivity of an author based on the
number of published articles. (Lotka), Ranking of words
in a text based on frequency of occurrence of words.
(Zipf), Productivity count of a literature, identifying the
peers, social change and the core journals etc. (Citation
Analysis), Bibliographic control, Preparation of
retrospective bibliography and better Library
Management. Hence We can conclude that, There is an
important role of Bibliometrics and Bibliometrics Laws
in the field of Library and Information Science.
