A comparison of semantic tagging with syntactic Part-of-Speech tagging leads us to propose that a domain-independent semantic tagger for English corpora should not aim to annotate each word with an atomic ‘sem-tag’, but instead that a semantic tagging should attach to each word a set of semantic primitive attributes or features. These features should include: − lemma or root, grouping together ...

The coefficient of isothermal compressibility (oil compressibility) is defined as the fractional change of oil volume per unit change in pressure. Though the oil compressibility so defined frequently appears in the partial-differential equations describing fluid flow in porous media, it is rarely used in this form in practical engineering calculations. Instead, oil compressibility is usually as...

Suppose we have a family F of sets. For every S ∈ F , a set D ⊆ S is a defining set for (F , S) if S is the only element of F that contains D as a subset. This concept has been studied in numerous cases, such as vertex colorings, perfect matchings, dominating sets, block designs, geodetics, orientations, and Latin squares. In this paper, first, we propose the concept of a defining set of a logi...

In a given graph G, a set of vertices S with an assignment of colors is said to be a defining set o f the vertex coloring o f G, if there exists a unique extension of the colors of S to a z(G)coloring of the vertices of G. The concept of a defining set has been studied, to some extent, for block designs and also under another name, a critical set, for latin squares. In this note we extend this ...

This paper reports the results of a workshop held at ECOOP’99. The workshop was set up to find answers to questions fundamental to the definition of a semantics for the Unified Modelling Language. Questions examined the meaning of the term semantics in the context of UML; approaches to defining the semantics, including the feasibility of the meta-modelling approach; whether a single semantics i...

The production possibility set (PPS) is defined as the set of all inputs and outputs of a system in which inputs can produce outputs. In data envelopment analysis (DEA), identification of the strong defining hyperplanes of the empirical production possibility set (PPS) is important, because they can be used for determining rates of change of outputs with change in inputs. Also, efficient hyperp...

A defining set of a block design is a subset of the blocks of the design which are a subset of no other design with the same parameters. This paper describes and proves the existence of a certain type of set of blocks in the infinite family of Steiner triple systems isomorphic to the points and lines of the projective geometries over GF(2). It is then proven that these sets of blocks are defini...

recent growth and developments in internet and electronic services play a significant role in banking industry all over the world especially in iran. it caused an intensive competition between governmental and non- governmental banks in the field of using e-banking services in a way that each bank attempts to attract more customers using high-quality e-services. ways of delivering services, qua...

A set of blocks which can be completed to exactly one t-(v, k, A) design is called a defining set of that design. A known algorithm is used to determine all smallest defining sets of the 11 non-isomorphic 2-(9,4,3) designs. Nine of the designs have smallest defining sets of eight blocks each; the other two have smallest defining sets of six blocks each. Various methods are then used to find all...

The set of all m-tuples of compatible full conditional distributions on discrete random variables is an algebraic set whose defining ideal is a unimodular toric ideal. We identify the defining polynomials of these ideals with closed walks on a bipartite graph. Our algebraic characterization provides a natural generalization of the requirement that compatible conditionals have identical odds rat...
