background; water treatment sometimes needs a coagulation and flocculation process to remove suspended and colloidal materials. inorganic coagulants used create concerns about pollution of the environment and harmful effects on the human’s health. the studies carried out previously indicated the capability of an active coagulant agent extracted from descurainia sophia seed to remove turbidity o...

Large amounts of the major storage proteins, beta-conglycinin and glycinin, in soybean (Glycine max) seeds hinder the isolation and characterization of less abundant seed proteins. We investigated whether isopropanol extraction could facilitate resolution of the low abundant proteins, different from the main storage protein fractions, in one-dimensional polyacrylamide gel electrophoresis (1D-PA...

Relation extraction is a fundamental task in information extraction. Different methods have been studied for building a relation extraction system. Supervised training of models for this task has yielded good performance, but at substantial cost for the annotation of large training corpora (About 40K same-sentence entity pairs). Semi-supervised methods can only require a seed set, but the perfo...

Seed point is prerequired condition for tracking based method for extracting centerline or vascular structures from the angiogram. In this paper, a novel seed point detection method for coronary artery segmentation is proposed. Vessels on the image are first enhanced according to the distribution of Hessian eigenvalue in multiscale space; consequently, centerlines of tubular vessels are also en...

Study was undertaken with the objective to develop a simple method for isolation of karanjin from Karanja (Pongamia pinnata Linn.) seed oil. The seed oil was subjected to liquid–liquid extraction with methanol. The extract was further subjected to solvent partitioning followed by crystallization to get karanjin, purity of which was ascertained by HPLC. The purity of isolated karanjin was found ...

This paper presents a clustering approach that simultaneously identifies product features and groups them into aspect categories from online reviews. Unlike prior approaches that first extract features and then group them into categories, the proposed approach combines feature and aspect discovery instead of chaining them. In addition, prior work on feature extraction tends to require seed term...

Information extraction systems usually require two dictionaries: a semantic lexicon and a dictionary of extraction patterns for the domain. We present a multilevel bootstrapping algorithm that generates both the semantic lexicon and extraction patterns simultaneously. As input, our technique requires only unannotated training texts and a handful of seed words for a category. We use a mutual boo...
