Abstractive summarization is the ultimate goal of document summarization research, but previously it is less investigated due to the immaturity of text generation techniques. Recently impressive progress has been made to abstractive sentence summarization using neural models. Unfortunately, attempts on abstractive document summarization are still in a primitive stage, and the evaluation results...

The growing demand for raw materials requires the optimization of extractive processes and innovative approaches, such as recovery quarrying processing waste. Waste from gneiss (ranging blocks up to residual sludge) used dimension stone (Beola Serizzo Piedmont, northern Italy) were characterized chemistry, mineralogy, petrography: quartz feldspars (plagioclase K-feldspar) are most abundant mine...

The root of Heliotropium indicum is reported to have good medicinal values in traditional system of medicines. Commonly called as Indian Turnsole, is a herb with slightly woody at base. It is distributed in the tropical and temperate regions of the world and found throughout India The present study deals with phytochemical investigations of Heliotropium indicum root including determination of l...

1,3-Butadiene, BD is produced from C4-cut by extractive distillation. The separation of 1,3-Butadiene from C4-cut is not possible through the conventional distillation processes, because several mixtures have consisted of close boiling points constituents and make azeotrope. The BASF extraction distillation process in BD unit of Jam and Amirkabir Petrochemical Company improves the relative vola...

Anacyclus pyrethrum DC. roots have important role in the traditional Ayurvedic and Unani systems of holistic health and herbal medicine of the East. Especially the roots of A. pyrethrum are reported to have good medicinal values in traditional system of medicine. The pres...

This Ph.D. thesis is the result of several years of research on automatic text summarization. Three major contributions are presented in the form of published and yet to be published papers. They follow a path that moves away from extractive summarization and toward abstractive summarization. The first article describes the HexTac experiment, which was conducted to evaluate the performance of h...
