Many connectionist language processing models have now reached a level of detail at which more realistic representations of semantics are required. In this paper we discuss the extraction of semantic representations from the word co-occurrence statistics of large text corpora and present a preliminary investigation into the validation and optimisation of such representations. We find that there...

This paper describes the Oki Information Extraction system as used for MUC-7 evaluation [1][2]. The tasks we have conducted are Named Entity, Co-reference, Template Element and Template Relation. Each module is implemented using MT system modules and pattern recognition modules. Our purposes to participate MUC-7 evaluation are to evaluate howMT system modules are e ective for other application ...

As one emerging metadata standard for the Semantic Web, FOAF defines an RDF vocabulary for expressing metadata about people and the relation among them. This paper proposes a novel keyword extraction method to extract FOAF metadata from the Web. The proposed method is based on co-occurrence information of words. Our method extracts relevant keywords depending on the context of a person. Our exp...

Relation extraction is the task of finding semantic relations between two entities from text. In this paper, we propose a novel feature-based Chinese relation extraction approach that explicitly defines and explores nine positional structures between two entities. We also suggest some correction and inference mechanisms based on relation hierarchy and co-reference information etc. The approach ...

Abstract Citrus juice processing residues are mainly composed of peel, juice sack and seed. The peel, especially, consists of bioactive compounds such as flavones. Supercritical carbon dioxide (SC-CO2) extraction of flavonoid was carried out at a pressure of 30 MPa and temperature ranging from 80 to 160°C. Ratio of water and ethanol as a co-solvent was varied from 0 to 100%. Flavonoids such as ...

An effective extraction of the fiberized cane juice has been obtained from a prepared extraction column. Oligosaccharides co~nposed of glucose and fructose were found in both cane juice and in raw sugar. The oligosaccharides found In the juice and raw sugar were probably produced by enzymatic or bacterial reactions occurring in cane which had had a delay of 24 h or Inore between cutting and pro...

Extracting high-purity DNA directly from soil has become essential for the study of microorganisms in environmental samples. However, many soils contain compounds that inhibit enzymes involved in manipulating DNA. In this study, chemical flocculation using multivalent cations was investigated as a potential method for eliminating soil-based inhibitors during the extraction process. The addition...

With the currently growing interest in the Semantic Web, describing user semantics to model users and their social relationships is coming to play an important role. This paper proposes a novel keyword extraction method to extract user semantics from the Web. Based on co-occurrence information of words, the proposed method extracts relevant keywords depending on the context of a person. Our eva...
