In this paper, we propose a time-line based framework for topic summarization in Twitter. We summarize topics by sub-topics along time line to fully capture rapid topic evolution in Twitter. Specifically, we rank and select salient and diversified tweets as a summary of each sub-topic. We have observed that ranking tweets is significantly different from ranking sentences in traditional extracti...

In this work, new biodegradable ABCBA type pentablock copolymers with different mole ratio of L-lactide and PPDO-b-PEG-b-PPDO triblock copolymer were synthesized and characterized. In the first step, PPDO-b-PEG-b-PPDO triblock copolymer was synthesized via a ring-opening polymerization of P-DiOxanone (PDO) monomer with Poly (Ethylene Glycol) (P...

there are different methodes for performance evaluation of economic development plans and ranking them in comparison with each other. these methods are founded on both quantitative and qualitative approaches. however, real world events are based upon uncertainty and since quantitative methods, unlike their names, are not accurate enough, they do not seem to be efficient in qualitative decision-...

Good implementation of corporate governance principles is considered as an important component for stability and soundness of a financial institution. An extensive body of literature has reviewed the effects of corporate governance on the performance of corporations. The majority of these studies have found more corporate values for implementing the principles. Therefore, the assessment of comp...

Abstract This study comprehensively assesses the performance of 29 Coupled Model Intercomparison Project Phase 6 (CMIP6) Global Climate Models (GCMs) and their ensemble mean (ENS_MEAN) over Vietnam. The spatiotemporal variability near-surface temperature precipitation is thoroughly evaluated for 30-year historical period 1985–2014. Results show that models can reasonably reproduce observational...

Today, users expect a variety of digital libraries to be searchable from a single Web page. The German Vascoda project provides this service for dozens of information sources. Its ultimate goal is to provide search quality close to the ranking of a central database containing documents from all participating libraries. Currently, however, the Vascoda portal is based on a non-cooperative metasea...

T research examines whether a low-ranking member in a high-status category (e.g., a low-end model of a high-end brand) or a high-ranking member in a low-status category (e.g., a high-end model of a low-end brand) is favored, holding the objective qualities of the items constant. Brand equity research suggests that the quality of a brand is more important than the ranking of a product within a b...
