Text mining of biomedical literature: discovering new knowledge

Biomedical literature is increasing day by day. The present scenario shows that the volume of literature regarding “coronavirus” has expanded at a high rate. In this study, text mining technique has been employed to discover something new from the published literature. The main objectives of this study are to show the growth of literature (Jan-Jun, 2020), extract document section, identify latent topics, find the most frequent word, represent the bag of words, and the hierarchical clustering. We have collected 16500 documents from PubMed. This study finds most number of documents (11499) belong to May and June. We explore “betacoronavirus” as the leading document section (3837); “covid” (29890) as the most frequent word in the abstracts; and positive-negative weights of topics. Further, we measure the term frequency (TF) of a document title in the bag of words model. Then we compute a hierarchical clustering of document titles. It reveals that the lowest distance the selected cluster (C133) is 0.30. We also have made a discussion over future prospects and mentioned that this paper can be useful to researchers and library professionals for knowledge management

Discovering Topics from the Titles of the Indian LIS Theses

A lot of text data is being generated on the web in the form of scholarly articles, doctoral thesis, social media, library databases, and data archives. They are easy to use but complicated to process for research works. That is exactly why text mining is required and topic modeling is one of the most important techniques involved in text mining. In this paper, an attempt has been made to discover topics from the thesis titles (uploaded theses) in the field of Library and Information Science (LIS). For this work, the text data (n=2132) has been obtained from the Shodhganga. Then, topic modeling through Latent Dirichlet Allocation (LDA) has been applied. After employing preliminary investigation, the findings show: State universities of India have the highest contribution of the thesis (78.06%); most theses (106) belong to Karnatak University, and 60.83% of thesis falls under the period 2011-2020. The main results of this paper are (a) The keyword “library” (0.204) has the highest score regarding 10 topics and “Library use” can be inferred as the major topic; (b) the keywords “information”, “technology”, “communication”, “survey”, “comparative”, “plant”, “scientist”, “city”, “support”, and “small” were discussed over 266 titles; and (c) “study”, “university libraries”, and “information-seeking behaviour’ are the most frequent n-grams appeared in the titles. This work can be taken towards future research for more improvement and new applications

Citation Analysis of Scholarly Publications on Indigenous Knowledge

Matter induced charge symmetry breaking and pion form factor in nuclear medium

Medium modification of pion form factor has been evaluated in asymmetric nuclear matter. It is shown that both the shape and the pole position of the pion form factor in dense asymmetric nuclear matter is different from its vacuum counterpart with $\rho$-$\omega$ mixing. This is due to the density and asymmetry dependent $\rho$-$\omega$ mixing which could even dominate over its vacuum counterpart in matter. Effect of the in-medium pion factor on experimental observables {\it e.g.}, invariant mass distribution of lepton pairs has been demonstrated.Comment: Final Version to appear in Jour. Phys.

Electromagnetic Radiation from Hot and Dense Hadronic Matter

The modifications of hadronic masses and decay widths at finite temperature and baryon density are investigated using a phenomenological model of hadronic interactions in the Relativistic Hartree Approximation. We consider an exhaustive set of hadronic reactions and vector meson decays to estimate the photon emission from hot and dense hadronic matter. The reduction in the vector meson masses and decay widths is seen to cause an enhancement in the photon production. It is observed that the effect of $\rho$-decay width on photon spectra is negligible. The effects on dilepton production from pion annihilation are also indicated.Comment: To appear in Nucl. Phys.

Photons from Hadronic Matter at Finite Temperature

Temperature dependence of hadronic decay widths and masses are studied within the framework of an effective Lagrangian approach. At finite temperature the hadronic masses do not seem to follow a universal scaling law. Considering an exhaustive set of hadronic reactions and vector meson decays we have estimated the photon spectrum emitted from hot hadronic matter taking into account medium effects through thermal loop corrections on the hadronic decay widths and masses. An enhancement in photon emission rate is obtained when we use the in-medium masses of vector mesons in our calculations. It is observed that the effect of $\rho$ decay width on the photon spectra is negligible.Comment: changed content, added references and figures.(30 pages, Figures included).
