Entity Set Expansion, which refers to expanding a human-input seed set to a more complete set which belongs to the same semantic category, is an important task for open information extraction. Because human-input seeds may be ambiguous, sparse etc., the quality of seeds has a great influence on expansion performance, which has been proved by many previous researches. To improve seeds quality, t...

Sicklepod (Senna obtusifolia L., Fabaceae) is a leguminous plant that thrives unwanted in crop fields such as soybean farms and is therefore described as a weed especially in many Southeastern States in the US. Although the recent introduction of “round-up-ready” soybeans mitigates infestation of the beans by sicklepod, the latter is so prolific that even volunteer stands yield over a 1120 kg/h...

Previous studies on extracting class attributes from unstructured text consider either Web documents or query logs as the source of textual data. Web search queries have been shown to yield attributes of higher quality. However, since many relevant attributes found in Web documents occur infrequently in query logs, Web documents remain an important source for extraction. In this paper, we intro...

The wheat seed used was stored at 4 f 1 "C until required and before use was washed with approx. 2 litres of distilled water per lOOg of seed. The seeds were germinated in the dark on moist filter papers a t 20"C+ 1°C. The extraction of chromatin from the ungerminated seeds was based on that of Simon & Becker (1976). Approx. 25g of dry seed was washed, then homogenized in approx. lOOml of extra...

The effects of air-drying and freeze-drying on the extraction yields and quality of oils from Quebec sea buckthorn (cv. Indian-summer) seeds and pulp were studied. Oil extractions were carried out using hexane. Air-dried (ADS) and freeze-dried (FDS) seeds, gave a similar extraction yields ( 12% w/w), whereas those of air-dried (ADP) and freeze-dried (FDP) pulps were significantly different (35....

We present an information extraction system that decouples the tasks of finding relevant regions of text and applying extraction patterns. We create a self-trained relevant sentence classifier to identify relevant regions, and use a semantic affinity measure to automatically learn domain-relevant extraction patterns. We then distinguish primary patterns from secondary patterns and apply the pat...

The main objective of this research is to develop a methodology for identifying different varieties of paddy seeds using morphological features. Morphological features are powerful tool which could separate the different varieties of seeds. Three varieties of paddy seeds are taken that are classified according to their morphological feature range. Image of paddy seeds was acquired by a canon di...

In this study, the process of separating and analyzing oils from some plant seeds such as Washingtonia tree Silybum marianum(kulgan) Soxhlat apparatus was used in extraction process, where performed using organic solvents (Hexane Petroleum ether). Then appreciation percentage oil these plants. It found that marianum contain a higher than tree. Then, active functional groups were identified (FT-...
