This paper enlarges classical syllogistic logic with assertions having to do with comparisons between the sizes of sets. So in addition to assertions like All x are y and Some x are y, we also have There are at least as many x as y, and There are more x than y. Our work also allows all nouns to be complemented. We thus obtain sentences equivalent to No x are y and At least half of the universe are x. We work on finite models exclusively. We formulate a syllogistic logic for our language. The main result is a soundness/completeness theorem. The logic has a rule of ex falso quodlibet, and reductio ad absurdum is admissible. There are efficient algorithms for proof search and model construction, and the logic has been implemented.

This paper proposes a formalization of the class of sentences quantified by most, which is also interpreted as proportion of or majority of depending on the domain of discourse. We consider sentences of the form “Most A are B”, where A and B are plural nouns and the interpretations of A and B are infinite subsets of  N . There are two widely used semantics for Most A are B: (i)  C(A∩B)>C(A∖B)  and (ii)  C(A∩B)>C(A)2 , where C(X) denotes the cardinality of a given finite set X. Although (i) is more descriptive than (ii), it also produces a considerable amount of insensitivity for certain sets. Since the quantifier most has a solid cardinal behaviour under the interpretation majority and has a slightly more statistical behaviour under the interpretation proportional of, we consider an alternative approach in deciding quantity-related statements regarding infinite sets. For this we introduce a new semantics using natural density for sentences in which interpretations of their nouns are infinite subsets of  N , along with a list of the axiomatization of the concept of natural density. In other words, we take the standard definition of the semantics of most but define it as applying to finite approximations of infinite sets computed to the limit.

Bipolar neutrosophic matrices (BNM) are obtained by bipolar neutrosophic sets. Each bipolar neutrosophic number represents an element of the matrix. The matrices are representable multi-dimensional arrays (3D arrays). The arrays have nested list data type. Some operations, especially the composition is a challenging algorithm in terms of coding because there are so many nested lists to manipulate. This paper presents a Python tool for bipolar neutrosophic matrices. The advantage of this work, is that the proposed Python tool can be used also for fuzzy matrices, bipolar fuzzy matrices, intuitionistic fuzzy matrices, bipolar intuitionistic fuzzy matrices and single valued neutrosophic matrices.

In recent years, "mathematical orientations on real-life problems", which continue to increase, began to make a significant impact. Information systems for many decision-making problems consist of uncertain, incomplete, indeterminate and indiscernible structures and components. Classical set theory and interpretation methods fail to represent, express and solve the problems of these types or cause to make wrong decisions. For this reason, in this study, we provide definitions and methods to present information and problem representations in more detail and precision. This paper introduces three new topologies called covering-based rough fuzzy, covering-based rough intuitionistic fuzzy and covering-based rough neutrosophic nano topology. Some fundamental definitions such as open set, closed set, interior, closure and basis are given. Neutrosophic definitions and properties are mainly investigated. We give some real life applications of covering-based rough neutrosophic nano topology in the final part of the paper and an explanatory example of decision making application by defining core point.

This paper presents a novel social choice theory based multi-criteria decision method under neutrosophic environment. Our hybrid method consists of classical methods and an aggregation operator used in social choice theory. In addition to this, we also use distributed in-determinacy form function in our method to provide a more sensitive indeterminacy approach towards accuracy functions. We also consider reciprocal property for all individuals. This provides, as in intuitionistic fuzzy decision making theory, a consistent decision making for each individual. The solution approach presented in this paper in group decision making is treated under neutrosophic individual preference relations. These new approaches seem to be more consistent with natural human behaviour, hence should be more acceptable and implementable. Moreover , the use of a similar approach to develop some deeper soft degrees of consensus is outlined. Finally, we give a Python implementation of our work in the Appendix section.

This paper enlarges classical syllogistic logic with assertions having to do with comparisons between the sizes of sets. So it concerns a logical system whose sentences are of the following forms: All x are y and Some x are y, There are at least as many x as y, and There are more x than y. Here x and y range over subsets (not elements) of a given infinite set. Moreover, x and y may appear complemented (i.e., as x and y), with the natural meaning. We formulate a logic for our language that is based on the classical syllogistic. The main result is a soundness/completeness theorem. There are efficient algorithms for proof search and model construction.

We show how to build the surface model over a data sample from agriculture science after the theoretical structure of the modeling is introduced. As a sampler application for agriculture systems, we give a visualization of Bézier surface model of an estimation of a given yield of bean seeds grown in a field over a period.

Neutrosophic set concept is defined with membership, non-membership and indeterminacy degrees. This concept is the solution and representation of the problems with various fields. In this paper, a geometric model is introduced for Neutrosophic data problem for the first time. This model is based on neutrosophic sets and neutrosophic relations. Neutrosophic control points are defined according to these points, resulting in neutrosophic B` ezier curves.

In this paper, we study the logic of language of L(More, IA). The logic contains the quantifier called '' more '' which makes cardinality comparisons can not be expressed in the language of the first order logic. The sentence forms are basically the form of ''There are more y than x .'' with x and y being common plural nouns. The sentence forms of common plural nouns combined with intersecting adjectives are ''There are more b y than a x. " with the intersecting adjectives a and b. We focus on derivation algorithms of the sentences having this type of quantifier and algorithms of construction of counter-models when the derivations are not provided.

This paper presents labeled digraph representations of logics of All, Some, No,
More and At Least by using algebraic properties of derivations of the logics. The logics of
All, Some and No come from the Aristotalian syllogisms. The syllogisms contain sentence
forms of All p are q, Some p are q, No p are q where p and q are plural nouns. The logics
of At least and More have respectively the form of “There are at least as many p as q”
and “There are more p than q” where p and q are plural nouns. Especially, labeled digraph
representations of logics of At least and More are a crucial position since languages of the
logics are not expressible in first order language.

The aim of this paper is to provide a contribution to the natural logic program which explores logics in natural language. The paper offers two logics called  R(∀,∃)  and  G(∀,∃)  for dealing with inference involving simple sentences with transitive verbs and ditransitive verbs and quantified noun phrases in subject and object position. With this purpose, the relational logics (without Boolean connectives) are introduced and a model-theoretic proof of decidability for they are presented. In the present paper we develop algebraic semantics (bounded meet semi-lattice) of the logics using congruence theory.

In this paper, we define the neutrosophic valued (and generalized or G) metric spaces for the first time. Besides, we newly determine a mathematical model for clustering the neutrosophic big data sets using G-metric. Furthermore, relative weighted neutrosophic-valued distance and weighted cohesion measure, is defined for neutrosophic big data set. We offer a very practical method for data analysis of neutrosophic big data although neutrosophic data type (neutrosophic big data) are in massive and detailed form when compared with other data types.

We introduce refined concepts for neutrosophic quantum computing such as neutrosophic quantum states and transformation gates, neutrosophic Hadamard matrix, coherent and decoherent superposition states, entanglement and measurement notions based on neutrosophic quantum states. We also give some observations using these principles. We present a number of quantum computational matrix transformations based on neutrosophic logic and clarify quantum mechanical notions relying on neutrosophic states. The paper is intended to extend the work of Smarandache by introducing a mathematical framework for neutrosophic quantum computing and presenting some results.

This paper is an extended version of " A Lattice Theoretic Look: A Negated Approach to Adjectival (Intersective, Neutrosophic and Private) Phrases'' in INISTA 2017. Firstly, some new negations of intersective adjectival phrases and their set-theoretic semantics such as non-red non-cars and red non-cars are presented. Secondly, a lattice structure is built on positive and negative nouns and their positive and negative intersective adjectival phrases. Thirdly, a richer lattice is obtained from previous one by adding neutrosophic prefixes neut and anti to intersective adjectival phrases. Finally, the richest lattice is constructed via extending the previous lattice structures by private adjectives (fake, counterfeit). These lattice classes are called Neutrosophic Linguistic Lattices (NLL). In the last part of the paper (Section 4 does not take place in the paper introduced in INISTA 2017), noun and adjective based positive and negative sub-lattices of NLL are introduced.

This article presents a technical construction of reasoning and counter-models for some sentences called
fragments as in [9] in English. Speaking English and logical inferences are brought together in computer based
approach to natural language. Not only the inferences in the language [7] are given but also counter-model
constructions in case of no inference from input sentences. Approach of this construction considers usage of
minimal number of set elements.

This paper proposes a formalization of the class of sentences quantified by most, which is also interpreted as proportion of or majority of depending on the domain of discourse. We consider sentences of the form "Most A are B ", where A and B are plural nouns and the interpretations of A and B are infinite subsets of N. There are two widely used semantics for Most A are B : (i) C(A ∩ B) > C(A \ B) and (ii) C(A ∩ B) > C(A) 2 , where C(X) denotes the cardinality of a given finite set X. Although (i) is more descriptive than (ii), it also produces a considerable amount of insensitivity for certain sets. Since the quantifier most has a solid cardinal behaviour under the interpretation majority and has a slightly more statistical behaviour under the interpretation proportional of, we consider an alternative approach in deciding quantity-related statements regarding infinite sets. For this we introduce a new semantics using natural density for sentences in which interpretations of their nouns are infinite subsets of N, along with a list of the axiomatization of the concept of natural density. In other words, we take the standard definition of the semantics of most but define it as applying to finite approximations of infinite sets computed to the limit.

Abstract:
This paper considers the quantified simple sentences by \textit{Most}, sometimes referred to as proportional, sometimes the majority. The sentence form: \textit{Most A are B} where \textit{A} and \textit{B} are plural nouns. A and B range over elements of P(N). Moreover, A and B may appear complemented (i.e., as Non−A and Non−B). Two different but equivalent semantics are for \textit{Most A are B} as (i) C(A∩B)>C(A∖B) and (ii) C(A∩B)>C(A)2 where C(X) is the cardinality of the set X. Both semantics work well on finite sets but exhibit problematic behaviors on infinite sets since division is undefined on cardinal arithmetic. Although semantics (i) is more descriptive than semantics (ii), it also produces insensitivity for certain sets. \textquotedblleft Most" has a solid cardinal structure under the interpretation of the majority, and has the more statistical structure with proportional interpretation, and this statistical interpretation provides more flexible range of motion. For all these reasons, we introduce a new semantics with natural density for the sentences ranging over N. We also give an axiomatization of this logic.

SESSION 122718.1
TRUTH-VALUE/VALIDITY-VALUE CHART: TURKISH DRAFT
https://www.academia.edu/s/23b0282c21/truth-valuevalidity-chart-equations-1?source=link
In the first meeting of every class, I encourage the students to team up in groups of no more than 4. I ask the students to hand-in one completed assignment per group signed by all members. Of course, any student can disagree with the team and do a dissenting paper.

After suitable instruction and discussion I assign the class to fill in a blank chart in a way that is easiest for them.

I have found that getting the students to complete one chart prevents errors and confusions later in the course.

In the class meeting in which the assignment is turned in, I present one of my completed charts. After that I allow the students to take their papers back and change them as they wish.
PLEASE SUGGEST CORRECTIONS AND IMPROVEMENTS TO THE TRANSLATION OR THE ORIGINAL BLANK.
