Tell Me How to Survey: Literature Review Made Simple with Automatic Reading Path Generation
Recent years have witnessed the dramatic growth of paper volumes with plenty
of new research papers published every day, especially in the area of computer
science. How to glean papers worth reading from the massive literature to do a
quick survey or keep up with the latest advancement about a specific research
topic has become a challenging task. Existing academic search engines such as
Google Scholar return relevant papers by individually calculating the relevance
between each paper and query. However, such systems usually omit the
prerequisite chains of a research topic and cannot form a meaningful reading
path. In this paper, we introduce a new task named Reading Path Generation
(RPG) which aims at automatically producing a path of papers to read for a
given query. To serve as a research benchmark, we further propose SurveyBank, a
dataset consisting of large quantities of survey papers in the field of
computer science as well as their citation relationships. Each survey paper
contains key phrases extracted from its title and multi-level reading lists
inferred from its references. Furthermore, we propose a
graph-optimization-based approach for reading path generation which takes the
relationship between papers into account. Extensive evaluations demonstrate
that our approach outperforms other baselines. A Real-time Reading Path
Generation System (RePaGer) has been also implemented with our designed model.
To the best of our knowledge, we are the first to target this important
research problem. Our source code of RePaGer system and SurveyBank dataset can
be found on here.Comment: 16 pages, 12 figure
GhVTC1, the Key Gene for Ascorbate Biosynthesis in Gossypium hirsutum, Involves in Cell Elongation under Control of Ethylene
L-Ascorbate (Asc) plays important roles in cell growth and plant development, and its de novo biosynthesis was catalyzed by the first rate-limiting enzyme VTC1. However, the function and regulatory mechanism of VTC1 involved in cell development is obscure in Gossypium hirsutum. Herein, the Asc content and AsA/DHA ratio were accumulated and closely linked with fiber development. The GhVTC1 encoded a typical VTC1 protein with functional conserved domains and expressed preferentially during fiber fast elongation stages. Functional complementary analysis of GhVTC1 in the loss-of-function Arabidopsis vtc1-1 mutants indicated that GhVTC1 is genetically functional to rescue the defects of mutants to normal or wild type (WT). The significant shortened primary root in vtc1-1 mutants was promoted to the regular length of WT by the ectopic expression of GhVTC1 in the mutants. Additionally, GhVTC1 expression was induced by ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC), and the GhVTC1 promoter showed high activity and included two ethylene-responsive elements (ERE). Moreover, the 5′-truncted promoters containing the ERE exhibited increased activity by ACC treatment. Our results firstly report the cotton GhVTC1 function in promoting cell elongation at the cellular level, and serve as a foundation for further understanding the regulatory mechanism of Asc-mediated cell growth via the ethylene signaling pathway
