Complex semantics

And, of course, most of these packages—especially the complex semantics ones—are virtual at present. But some research projects have indeed built up the packages of primitives. (The example given here comes from [Muial91].)... 

Mapping of lexical terms and complex semantic categories to expressions in text (this is a term categorizer based on machine learning)... 

As stated, FMS suits holistic and conceptual tasks open for the use of intermo-dal and complex semantics. Such data are often noisier and show larger confidence ellipses around the samples in an individual factor map than data from a conventional profile. As shown in Fig. 8.3, more conceptual task would often involve the use of naive assessors, would need less concept alignment (assessor training), and would hence require a larger number of assessors. 

The four possible approaches are Complex Syntax/ Complex Semantics Complex Syntax/ Simple Semantics Simple Syntax/ Simple Semantics and Simple Syntax/ Complex Semantics. The former two are termed hypersemantic because the deep structure is the combination of all of the component structures. The latter two are termed metasemantic because the deep structure is the overlap of the components. 

The reason why this fourth choice is not populated by any widespread examples is the immense difficulty of devising a simple syntax which can support a complex semantics. The problem is that successful syntax needs to be created according to laws or rules, and it is always easier to have a whole lot of rules than it is to have a few, simple rules which do the same job. 

The Semantic Web Initiative supports two key needs in pharmaceuticals, first, the need to collect and represent complex forms of information in an intelligent, flexible form so that it is usable by computer tools and by scientists and clinicians and second, the need to gain insights or make decisions based on an aggregation of information that may share common entities, such as molecules, diseases, and intellectual property. 

It s possible to write a precise set of rules (that is, a program) for converting each diagram element into text. And given any complex piece of text—such as an action specification, with its pre- and postconditions and odd constructs such as pre and so on—it is possible to write a set of rules for converting it into a longer set of statements in terms of a much more basic set of ideas. These sets of rules are called the semantics of the language. 

Sensory. Although the basis for multivariate analysis was developed in the early 1900 s, its use in sensory analysis is relatively recent. These types of statistics, however, have been valuable in dealing with two fundamental problems which occur in sensory testing. First there are difficulties encountered when one attempts to breakdown complex sensory parameters into single semantic terms which can be rated, and second it is difficult to achieve the goal of every panelist having the same internal understanding of each term. Approaches to minimize these difficulties included 1) evaluation of semantic terms used by the panel to determine if the variables are unique or can be condensed to a new set of unique variables 2) evaluation of the panelists use of semantic terms to determine inconsistencies as well as the relative importance of the terms to food quality or discrimination.(8)... 

Dr. Kamiya has attempted to explain the role of the catalyst according to Reactions 13-15, and he has attempted to differentiate between these proposed reaction steps and the simplified Reactions 3 and 4. It is not clear to me what types of structures he is trying to portray by using the empirical formulae Co2+BrH and Co3+Br". There does not seem to be any evidence for any unusual complexes in these solutions, and there does not seem to be any need to postulate them. It really becomes a matter of semantics because nobody believes that in solution Br, for example, exists as such, but it must be solvated by or coordinated with other species. Dr. Kamiya also implies that the initiation step is a direct reaction of the hydrocarbon with Co (III) ion. To my knowledge, a reaction such as this in acetic acid solution has never been demonstrated. We have shown that the reaction between cobalt (III) acetate in acetic acid and toluene is negligibly slow. It would be more likely to consider the reaction... 

Note that the cis isomer lacks an improper axis of rotation and is therefore chiral, but that the trans isomer has a plane of symmetry and will be achiral in the absence of an asymmetric carbon in the phosphine ligand-28 As in the case of the previously encountered cyclopentadienyl complex (page 476), it can be argued whether the coordination number is 5 or 9. In either semantic interpretation these compounds are of considerable interest since isomerism in nine-coordinate complexes Is even less well documented than in those with coordination number 5.
