Algebraic expression

The basic set of operations for the relational model is known as the relational algebra. These operations enable a user to specify basic retrieval requests. The result of a retrieval is a new relation, which may have been formed from one or more relations. The algebra operations thus produce new relations, which can be further manipulated using operations of the same algebra.

As information extraction (IE) becomes more central to enterprise applications, rulebased IE engines have become increasingly important. In this paper, we describe SystemT, a rulebased IE system whose basic design removes the expressivity and performance limitations of current systems based on cascading grammars. SystemT uses a declarative rule language, AQL, and an optimizer that generates highperformance algebraic execution plans for AQL rules. We compare SystemT’s approach against cascading grammars, both theoretically and with a thorough experimental evaluation. ...

We develop a framework for formalizing semantic construction within grammars expressed in typed feature structure logics, including HPSG. The approach provides an alternative to the lambda calculus; it maintains much of the desirable ﬂexibility of uniﬁcationbased approaches to composition, while constraining the allowable operations in order to capture basic generalizations and improve maintainability.

From the system we call the ‘normal equation system’ we can solve K normal equations for K unknown beta coefficients. The straightforward representation of the solution is expressed in the matrix algebra. However, since the main purpose is the application and EViews. Other data analysis software is available, so we can easily find regression coefficients without remembering all the algebraic expressions.

SMOOTH AND DISCRETE SYSTEMS—ALGEBRAIC, ANALYTIC, AND GEOMETRICAL REPRESENTATIONS ˇ FRANTISEK NEUMAN Received 12 January 2004 What is a diﬀerential equation? Certain objects may have diﬀerent, sometimes equivalent representations. By using algebraic and geometrical methods as well as discrete relations, diﬀerent representations of objects mainly given as analytic relations, diﬀerential equations can be considered.

This is the ninth book containing examples from the Theory of Complex Functions. We shall here treat the important Argument Principle, which e.g. is applied in connection with Criteria of Stability in Cybernetics. Finally, we shall also consider the Manyvalued functions and their pitfalls. Even if I have tried to be careful about this text, it is impossible to avoid errors, in particular in the first edition. It is my hope that the reader will show some understanding of my situation.

We’ve known about algorithms for millennia, but we’ve only been writing computer programs for a few decades. A big difference between the Euclidean or Eratosthenes age and ours is that since the middle of the twentieth century, we express the algorithms we conceive using formal languages: programming languages. Computer scientists are not the only ones who use formal languages. Optometrists, for example, prescribe eyeglasses using very technical expressions, such as “OD: 1.25 (0.50) 180◦ OS: 1.00 (0.25) 180◦”, in which the parentheses are essential.

CLASSICAL GEOMETRY — LECTURE NOTES DANNY CALEGARI 1. A CRASH COURSE IN GROUP THEORY A group is an algebraic object which formalizes the mathematical notion which expresses the intuitive idea of symmetry. We start with an abstract deﬁnition. Deﬁnition 1.1. A group is a set G and an operation m : G × G → G called multiplication with the following properties: (1) m is associative. That is, for any a, b, c ∈ G, m(a, m(b, c)) = m(m(a, b), c) and the product can be written unambiguously as abc. (2) There is a unique element e ∈ G called the...

The interplay between geometry and topology on complex algebraic varieties is a classical theme that goes back to Lefschetz [L] and Zariski [Z] and is always present on the scene; see for instance the work by Libgober [Li]. In this paper we study complements of hypersurfaces, with special attention to the case of hyperplane arrangements as discussed in OrlikTerao’s book [OT1]. Theorem 1 expresses the degree of the gradient map associated to any homogeneous polynomial h as the number of ncells that have to be added to a generic hyperplane section D(h) ∩ H to obtain the complement in...

To solve these problems, the SEQ and PREDATOR systems introduce a spe cial sublanguage, called SEQUINfor queries on sequences [Seshadri et al. 1994, 1995; Seshadri 1998]. SEQUIN works on sequences in combination with SQL working on standard relations; query blocks from the two languages can be nested inside each other, with the help of directives for converting data be tween the blocks.
