The rapid expansion of the artisanal and small-scale gold mining (ASGM) industry in developing countries has marginalized the local communities in poverty, and resulted in occupational exposure to mercury via the gold extraction process. We investigated the mercury exposure of the mining workers lived inside and outside the mining area. Based on the occupations of the contributors, the hair sam...

While user attribute extraction on social media has received considerable attention, existing approaches, mostly supervised, encounter great difficulty in obtaining gold standard data and are therefore limited to predicting unary predicates (e.g., gender). In this paper, we present a weaklysupervised approach to user profile extraction from Twitter. Users’ profiles from social media websites su...

We investigated the potential of tailings generated from chrysotile asbestos fiber production as a source iron, nonferrous metals, and gold. proposed use granulometric separation systematically examined different enrichment processes, namely magnetic separation, gravity concentration, using Knelson concentrator, to extract valuable components. The characterization initial tailing samples reveal...

This paper describes a case study on methods for automatically extracting qualia relations from dictionary glosses in Italian, namely the Senso Comune De Mauro Dictionary (SCDM). The qualia extraction has been addressed by means of a pattern-based approach and lexical match with an Italian generative lexicon based language resource, PAROLE-SIMPLECLIPS (PSC). The evaluation of the extraction app...

Citrate-stabilized gold nanoparticles were found to spontaneously self-assemble into a lustrous film at a bare water-propylene carbonate interface after vigorous shaking, due to the extremely low interfacial tension. The presence of an electron donor, tetrathiafulvalene, in the oil phase, led to the extraction of particles into the organic phase.

Association with Hg(2+) enhances the hydrophobicity and triggers the cloud point extraction of approximately 4 nm-diameter gold nanoparticle probes functionalized with mercaptopropionic acid and homocystine, which results in the color change of the TX-114-rich phase from colorless to red, and therefore provides a novel approach for visual and colorimetric detection of Hg(2+) with ultrahigh sens...

SemEval 2016 Task 12 addresses temporal reasoning in the clinical domain. In this paper, we present our participation for relation extraction based on gold standard entities (subtasks DR and CR). We used a supervised approach comparing plain lexical features to word embeddings for temporal relation identification, and obtained above-median scores.

Finding relationships between words in text and articles from Wikipedia is an extremely popular task known as wikification. However there is still no gold standard corpus for wikifiers comparison. We present WikifyMe, the online tool for collaborative work on universal test collection which allows users to easily prepare tests for two most difficult problems in wikification: word-sense disambig...
