Refining the Selectivity of Thesauri by Means of Statistical Analysis

چکیده
The importance of language and terminology for the law and the jurisprudence is beyond question because language is a central subject of a lawyer's work (Hatz 1963, Salton/McGill 1983). The particularity of the legal language is the use of a special vocabulary of legal terms which are used to express definite concepts. The presence of a particular term has specific connotations. Legal thinking is based on this vocabulary. The result is that legal language is more precise than natural language. An examination of the usage of legal terms in the different types of legal documents shows that certainty as well as ambiguity exists in the same domain or even the same document (i.e. the usage is normally more precise in statutes or judicial decisions but is often blurred in legal literature) (Allen 1982). Whereas lawyers are very skillful in handling this speciality of jurisprudence, the automatic representation of this meta-knowledge has been proved to be a challenging task.

متن کاملRefining membership degrees obtained from fuzzy C-means by re-fuzzification
Fuzzy C-mean (FCM) is the most well-known and widely-used fuzzy clustering algorithm. However, one of the weaknesses of the FCM is the way it assigns membership degrees to data which is based on the distance to the cluster centers. Unfortunately, the membership degrees are determined without considering the shape and density of the clusters. In this paper, we propose an algorithm which takes th...
متن کاملCONCAT - Connotation Analysis of Thesauri Based on the Interpretation of Context Meaning
Knowledge acquisition constitutes the bottleneck for the creation of legal expert systems. Legal language must be formalised to such a degree that it can be processed automatically. We deal with this problem by supporting the process of creating a selective thesaurus for a legal information system which can be seen as prerequisite for further knowledge processing. This selectivity is obtained b...

Using surface analysis, simultaneous effects of temperature (260-380ºC) and ethanol concentration (0-1%) on dimethyl ether (DME) selectivity, yields of hydrocarbon and DME, and methanol conversion were investigated in methanol dehydration reaction over γ-Al2O3 catalyst. Methanol conversion and yield of hydrocarbon/DME were found to be significantly affected by temperature and the temperature-et...
