Plan of My work Collect Information about researchers Researcher Affiliation Journal Details Conference Details Books Details (Authors and Editors) Constructing a graph according to their activity. Defining Problem . Proposing/ Designing a new technique . Simulation and Performance Analysis of proposed technique.2 Anand Bihari

Introduction Many research professional are involved in activities like Publish a Journal paper, Conference paper, Books, Articles etc. Two or more than two persons works together . Our objective Find the relationship between professionals. How many professional are working in the same area. Which person are more active in a particular area. Which person are suitable for guidance in particular area.4 Anand Bihari
5.
Our Work So here we analyze research professional activity as mining. For analyzing research professional activity, we required three types of Information like Research Professional Data(Personal information) Activity Relationship between Research professional and their activity We extract data from IEEE, Springer, Science Direct, ACM digital library etc.5 Anand Bihari

Citation A citation can represent many types of links, such as links between authors, publication, journals and conferences. When researchers refers to another author’s works in their own publication work, they cite it. A citation index is a compilation of all the cited references form articles published during a particular year or period. A citation index allows to determine the researcher impact of publication according to the number of times it has been cited by other researcher. Self citation are not included in such citation count.6 Anand Bihari

h-index Invented by Jorge Hirsh at university of California in 2005. A popular method to measure the centrality of academic papers. h-index =number of your papers h that have been cited at least h times. The use of h-index aims at identifying researchers with more papers and relevant impact over a period of time. For any general “set of papers” one can arrange these papers in decreasing order of the number of citations they received. The h-index is then the largest rank h = r such that the paper on this rank (and hence also all papers on rank 1,…,h) has h or more citations. Hence the papers on ranks h + 1, h + 2, … have not more than h citations.9 Anand Bihari

g-index The g-index is introduced as an improvement of the h-index of Hirsh to measure the global citation performance of a set of articles. This set is ranked in decreasing order of the number of citations that they received, the g-index is the (unique) largest number such that the top g articles received (together) at least g2 citations. The g-index of an author is greater or equal to h-index(g>=h).11 Anand Bihari

g-index example(II) TC stands for the total number of citations for each paper on rank r = 1,2,... . ∑TC stands for the cumulative number of citations to the papers on rank 1,...,r (for each r). The h-index of author P1 is h = 2 and the g-index g = 2 Indeed h = 2 is the highest rank such that all papers on rank 1,...,h have at least 2 citations (and hence the papers on rank 3 or higher have not more than 2 citations). Also g = 2 is the highest rank such that the top 2 papers have at least 22 = 4 citations (here 4>= 4); on rank 3 we have 6 < 32 = 9 citations.13 Anand Bihari

Longevity Longevity reflects the length of one author’s academic life. We consider the year when one author publish his/her first paper as the beginning year of his/her academic life and the last paper as the end year. Then longevity can be defined as longevity(A)=YA(A’s last paper) – YA(A’s first paper) Example: let author A published first paper in 1997 and the last paper in 2011. Therefore, longevity of Author A = 2011 – 1997 = 1414 Anand Bihari

Future Work After designing a graph , we will implement mathematical equation or graph algorithm to find the meaningful value of a node. Research person are taken as vertices. Edge between them having some weight like activity between them. Find more influence(Active) person in such area. Find more influence person in the network. For this we will collect data from a website known as www.arnetminer.org . Learn Diversity, Sociability, Activity of researcher in social network.15 Anand Bihari
