  3. 3. Informertrics• Introduction There is no measurement (i.e meaningful data) without theory and notheory without data. The term “informetrics (Informetrie “German term”) was introduced byBlackert and Siegel (1979) and by Nacke (1979), to cover that part ofinformation science dealing with the measurement of informationphenomena and the application of mathematical methods to thediscipline’s problems.
  4. 4. Informetrics was adopted in 1987-88 as the short title for the publishedconference proceedings. Informetrics is an emerging subfield in Information Science, based on thecombination of quantitative studies of information flows, and advancedinformation retrieval and texts, and data mining.IntroductionInformertrics

  7. 7. Aspects of InformetricsInformetrics is the study of quantitative aspects of information. This includes :1) Production2) Dissemination3) Use of all forms of information, regardless of its form or origin.Informertrics
  8. 8. Informetrics is used in or applied to:Library ManagementThe Sociology of ScienceThe History of ScienceScience PolicyInformation RetrievalBeneficial for other fields between:Biometrics.Econometrics.Chemometrics.Quantitative Linguistics and so on.INFORMETRICS USED / APPLIED TO:InformertricsMoreover,  we  feel  that  a  real interaction  between  informetrics  and  biometrics, econometrics, Quantitative linguistics and so on would be very beneficial for all fields involved.
  9. 9. INFORMETRICS USED / APPLIED TO: [Conti…[Informertrics LIBRARY MANAGEMENTLibrary management is a sub-discipline of institutional management that focuses on specific issues faced by libraries. Library  management  involves  functions  such  as  Planning,  Organizing, Leading, and Controlling. Planning is about systematically making decisions about the library goals. Organizing is about assembling and coordinating human, financial, physical, informational, and other resources needed to achieve library goals.Leading is about functions that involve efforts on the part of the librarian to stimulate high performance by employees.Controlling about monitoring various library operations and services. These four management functions are highly integrated.
  10. 10. INFORMETRICS USED / APPLIED TO: [Conti…[Informertrics THE SOCIOLOGY OF SCIENCEThe sociology of scientific knowledge (SSK) is the study of science as a social activity, especially dealing with "the social conditions and effects of science, and with the social structures and processes of scientific activity. The  field  emerged  in  the  late  1960s  and  early  1970s  and  at  first  was  an almost exclusively British practice.
  11. 11. INFORMETRICS USED / APPLIED TO: [Conti…[Informertrics THE HISTORY OF SCIENCEThe history of science is the study of the historical development of science and scientific knowledge, including both the natural sciences and social sciences. Until the late 20th century, the history of science, especially of the physical and biological sciences, was seen as a narrative of true theories replacing false ones. 
  12. 12. INFORMETRICS USED / APPLIED TO: [Conti…[Informertrics Science PolicyScience policy is an area of public policy concerned with the policies that affect the conduct of the science and research enterprise, including the funding of science, often in pursuance of other national policy goals such as technological innovation to promote commercial product development, weapons development, health care and environmental monitoring. Science policy also refers to the act of applying scientific knowledge and consensus to the development of public policies. 
  13. 13. INFORMETRICS USED / APPLIED TO: [Conti…[Informertrics Information RetrievalInformation retrieval is the activity of obtaining information resources relevant to an information need from a collection of information resources. Searches can be based on metadata or on full-text indexing. Automated information retrieval systems are used to reduce what has been called "information overload". Many universities and public libraries use IR systems to provide access to books, journals and other documents. Web search engines are the most visible IR applications.
  14. 14. InformertricsInformetrics is one of the rare truly interdisciplinary research field, and the range of theoretical  and  methodological  approaches  is  rich,  which  is  the  strength  of  the discipline.Interdisciplinary Research Field
  15. 15. InformertricsInformetric Law’s / Regularities1. Bradford’s Law of Scattering2. Lotka’s Law3. Zipf’s Law4. Pareto’s Law
  16. 16. InformertricsThis  is  probably  the  most  prominent  of  the  informetric  regularities  within  the information sciences, perhaps because of its promise for application to the control of literature.  Bradford (1934) discovered  this  regularity  when  studying  the  extent  to which literature in a single discipline is scattered over a range of journals.Bradford’s Law of ScatteringLotka (1926) found that if he associated with each member of a group of chemists his article productivity, then the number of chemists. In Lotka’s, the mode of description of this  yield  distribution  is  that  of  the  traditional  statistical  probability  distribution function;  indeed,  of  the  informetric  regularities,  this  one  is  most  consistent  with traditional statistical descriptionLotka’s Law
  17. 17. InformertricsMany  of  the  informetric  regularities  depend  on  ranked  data.  The  most  prominent belongs to Zipf (1935), who analyzed the frequency of word occurrence in natural text.  He  found  that  if  he  multiplied  a  word’s  frequency  by  its  rank  in  number  of occurrences  in  text,  then  the  product  was  approximately  constant.  Zipf’s  law,  like Lotka’s law, can be related to the forms of description traditional in statistics.Zip’s Law
  18. 18. InformertricsInformetrics today offers many new possibilities for LIS Professionals. For those who want to explore Databases not only as a store of information but also as an analytical tool,  it  is  a  way  to  learn  how  to  explore  online  databases  not  only  for  accessing documents or finding facts, but only to trace the trends and developments in society, scientific disciplines or production and consumption.Offers New Possibilities for LIS Professionals
  19. 19. InformertricsThe field is becoming a scientific discipline that includes:•All the statistical and mathematical analyses related to the study of informationflows.•Evaluation of science and technology.•Library collection development.Becoming a Scientific Discipline
  20. 20. Extensions / Distribution of InformetricsInformetrics encompasses the fields of:Bibliometrics:Which studies quantitative aspects of recordedinformation.Librametrics:Used the term to include statistical approachesto the study of library and its servicesScientometrics:Its concerned with the quantitative features andcharacteristics of science and scientific research.Webometrics:Which studies quantitative aspects of theWorld wide Web.Cybermetrics:Which is similar to webometrics, but broadens its definitionInformertricsIn a digitally networkeduniverse, “webometrics”and sister terms like“netometrics” and“cybermetrics” signify theextension of informetricmethods and concepts toinformation transactionstaking place on the Internet.
