Topic models have been successfully applied in lexicon extraction. However, most previous methods are limited to document-aligned data. In this paper, we try to address two challenges of applying topic models to lexicon extraction in non-parallel data: 1) hard to model the word relationship and 2) noisy seed dictionary. To solve these two challenges, we propose two new bilingual topic models to...

safflower is a strategic plant regarding to its valuable nutrition value (45% extractable oil) and industrial uses. due to massive import of edible oil to the country as well as high potential for safflower cultivation, the research on production of safflower for oil extrusion purpose is of remarkable importance. the design of various processing and oil extraction units and also their optimizat...

Iterative bootstrapping methods are widely employed for relation extraction, especially because they require only a small amount of human supervision. Unfortunately, a phenomenon known as semantic drift can affect the accuracy of iterative bootstrapping and lead to poor extractions. This paper proposes an alternative bootstrapping method, which ranks relation tuples by measuring their distance ...

This paper presents the Fault-Tolerant Learning approach for term extraction. The approach extracts terms using automatically generated seeds instead of prior domain knowledge or annotated corpora. Thus it is applicable to any domain specific corpus and it is especially useful for resource-limited domains. Two classifiers are separately trained for prediction and verification to ensure the perf...

A faster and more efficient way of isolating and subsequently cleaning up the sterol fraction obtained from seed oils was developed based on an existing established method that used thin-layer chromatography (TLC) to isolate the sterol fraction (3). The newly developed method used solidphase extraction (SPE) to separate the sterol fraction from other compounds found in the unsaponifiable portio...

Pomegranate seed oil was extracted in a closed-vessel high-pressure microwave system. The characteristics of the obtained oil, such as fatty acid composition, free fatty acidity, total phenolic content, antioxidant activity and colour, were compared to those of the oil obtained by cold solvent extraction. Response surface methodology was applied to optimise extraction conditions: power (176-300...

An important relation in information extraction is the part-whole relation. Ontological studies mention several types of this relation. In this paper, we show that the traditional practice of initializing minimally-supervised algorithms with a single set that mixes seeds of different types fails to capture the wide variety of part-whole patterns and tuples. The results obtained with mixed seeds...

Our research aimed to optimize the oil extraction process and determine the fatty acids in Brucea javanica (L.) Merr. seeds. The extraction technology was optimized using response surface methodology. A Box-Behnken design was employed to investigate the effects of three independent variables on an ultrasonic-assisted extraction technique, namely, sonication time (X₁: 20-40 min), liquid-solid ra...
