WikiM: Metapaths based Wikification of Scientific Abstracts
In order to disseminate the exponential extent of knowledge being produced in
the form of scientific publications, it would be best to design mechanisms that
connect it with already existing rich repository of concepts -- the Wikipedia.
Not only does it make scientific reading simple and easy (by connecting the
involved concepts used in the scientific articles to their Wikipedia
explanations) but also improves the overall quality of the article. In this
paper, we present a novel metapath based method, WikiM, to efficiently wikify
scientific abstracts -- a topic that has been rarely investigated in the
literature. One of the prime motivations for this work comes from the
observation that, wikified abstracts of scientific documents help a reader to
decide better, in comparison to the plain abstracts, whether (s)he would be
interested to read the full article. We perform mention extraction mostly
through traditional tf-idf measures coupled with a set of smart filters. The
entity linking heavily leverages on the rich citation and author publication
networks. Our observation is that various metapaths defined over these networks
can significantly enhance the overall performance of the system. For mention
extraction and entity linking, we outperform most of the competing
state-of-the-art techniques by a large margin arriving at precision values of
72.42% and 73.8% respectively over a dataset from the ACL Anthology Network. In
order to establish the robustness of our scheme, we wikify three other datasets
and get precision values of 63.41%-94.03% and 67.67%-73.29% respectively for
the mention extraction and the entity linking phase
Propagation of non-linear waves in hot, ideal, and non-extensive quark-gluon plasma
We study the propagation of energy density perturbation in a hot, ideal
quark-gluon medium in which quarks and gluons follow the Tsallis-like momentum
distributions. We have observed that a non-extensive MIT bag equation of state
obtained with the help of the quantum Tsallis-like distributions gives rise to
a breaking wave solution of the equation dictating the evolution of energy
density perturbation. However, the breaking of waves is delayed when the value
of the Tsallis q parameter and the Tsallis temperature T are higher.Comment: Matches with the version accepted by the European Physical Journal
