The investigation presented in this paper is a novel method in question answering (QA) that enables a QA system to gain performance through reuse of information in the answer to one question to answer another related question. Our analysis shows that a pair of question in a general open domain QA can have embedding relation through their mentions of noun phrase expressions. We present methods for recognition of embedding property between a pair of questions by focusing on the techniques applied to match noun phrase mentions in the questions. We then take advantage from the discovery of embedding relationship and extract referent named entities corresponding to the noun phrase expression that are present in the answer of one question. The named entities will then be used as significant terms in the query generation phase of the QA system to retrieve more pertinent answers. Finally, we discuss on data set resources and system evaluation.

The limited language exposure available to the learners of English as a foreign language (EFL) decreases their chance of utilizing two important practices- questions and interactional modifications- in their classrooms, which according to interaction hypothesis are influential in language development. This study thus explores the possibilities of Computer Assisted Language Learning (CALL), and in particular, text-based online chat in increasing these opportunities. To do so, a total of eighteen paired intermediate EFL students were assigned to use a synchronous chat program to complete a set of seven communicative tasks outside their classroom over a period of seven weeks’ time. Their performance was later compared with that of the control group members who completed the same tasks but through in-class written interaction. The results show that participants in the former environment not only outperformed those in the latter in terms of both type and frequency of the interactional modifications, but also manifested higher level questioning abilities. However, since this study focused on the forms of questions rather than their cognitive value, further research is required to seek ways in which questions which call for speculative, inferential and evaluative thinking can develop.

questions are the most important and the most common feature of legal talk. questioning is the weapon that is used to test or challenge statements made by lay people and it is considered as a tool to make accusa-tions. Based on syntactic and formal features of questioning, which are important parts of any linguistic analysis, questions are categorized into two classes: closed and open questions. The criteria for choosing one form over the others is determined by pragmatic factors. In other words, the questioner chooses one form of questions on the base of pragmatic strategies that s/he adapts during questioning. This article is dedicated to exploring the crossroads where structural and pragmatic features of questions come together to achieve this goal. To this end, we combined two quantitative and pragmatic approaches. The data of the present research was gathered from four cases during interrogation processes in the court of Shiraz. The research findings indicate that pragmatic strategies determine the types of question forms and, also, closed questions have the most application in the interrogation process because they have a high level of control that can challenge the addressee’ s statements.

Any litigation is composed of a series of facts and rules the distinction between them is of great import. One may distinct the factual elements of litigation as "questions of fact" from the legal elements thereof classically called "questions of law". The parties to litigation as well as the judges who adjudicate the litigation always need to keep this distinction in mind to avoid misleading the process of adjudication. "The due process of law" requires that both the litigants and the judge play their own role in the proceeding; while the litigants are to deal with the questions of fact, the judge shall exclusively determine the questions of law. This essay tries to draw a clear and pragmatic border between the questions of fact and questions of law and present a logically well-defined criterion appropriate to apply by the tribunals and judicial officers in this effect.

There are several meanings for the term hermeneutics on the basis of its application.The uses of the word should be precisely clarified their meaning and the amis by using this term. Criticism domain of artwork has had the most damage due to the peculiar application of the word hermeneutics and its different equivalents such as interpretation, analysis of critics and rhetoricians and thinkers in their written works. If the meaning of the words in their applications and the users intention of the words is not clarified there would happen no immediate and clear action would be at hand, moreover the written works readers would be mislead in understanding the have wrong interpretation to that of the authors. Interpretation and understanding a phenomenon is impossible as for as some thinkers take understanding and interpretation as a unique entity. Human mental capabilities are in form that allows making meaning for every phenomenon or seek to discover the meaning. Such capacity is called as interpretive capacity. Texts are unveiled through interpretation.The aim of text interpretation and understanding is to get its meaning, meaning is the fruit of understanding.Dasani is an interpret or that has heaven and innately interprets the phenomenon. In order to interpret a text it is necessary to have a method. The text direct the interpreters in finding the methods of interpretation, in other words texts are direction of interpreters for interpretation. Studying the definitions of hermeneutics and analyzing the interpretation process nature is necessary for any researcher. Because interpretation, cognition and cosmology have innate relation and in addition to this, interpretation in art domain appears in the form of art critics. The question of what is hermeneutics and studying the general problems related to interpretation is the gist of this article.

A B S T R A C T Considering the location of vital centers in the heart of the cities, they are more affected by unexpected events. Hence, due to the probability of the loss of existing services and devastating effects on the social organization and the necessity to prepare essential needs of people and military agencies, planning and building the storage for essential items as a replacement for the damaged services are considered a critical factor in social and defensive reliability. This research tries to locate stockpile of essential Items in Mashhad by emphasizing passive defense criteria and analyzing stockpiles of essential items in terms of form communicational structure. The type of research is applied, and the research method is in theoretical discussion and formulation of mental models, descriptive-analytical and information-gathering methods, documents, questionnaires, and interviews. Moreover, the information analysis method is with the IHWP model in GIS software in the locating section. In the section on examining architectural patterns and forms is content analysis. The research results show that 20.61 percent of Mashhad has an optimal location potential, and 0.94 percent of city also has a favorable potential for location. Also, parts of the north-east and south of the city have the priority for location. The types of spatial organization of the rectangular form, including centralized, four-armed, introverted, and diagonal, were investigated in the architecture department. The centralized form is preferable to other forms for its capacity and access to exits and spatial organization Extended Abstract Introduction As a stockpile of essential items to facilitate the process of activities and to achieve goals, the warehouse plays a vital role in creating this flexibility in organizations. In fact, from the point of view of crisis management, the stockpile of essential items can play a significant role in the supply chain to deal with unforeseen internal or external incidents. Passive defense in the stockpile of essential items refers to measures that do not require expensive and challenging methods and solutions to protect the stockpile of essential items. Furthermore, it can help avoid the substantial expenses of monitoring the entire inventory and increasing non-conformities (such as theft, fire, non-conformity in the inventory and management inspection, fatal accidents, etc.) or reduce this amount. Choosing the form of the stockpile of essential items for essential items with a passive defense approach requires a comprehensive analysis based on defense principles such as hierarchical protection, nationwide coverage, dynamic protection, relative self-sufficiency, and minimum vulnerability. Therefore, in addition to placing this category of stockpile of essential items in Mashhad, the mentioned research also tries to establish a relationship between architectural forms and principles of defense to reduce vulnerability and improve the level of relief in times of crisis.   Methodology The current type of research is applied, and the research method is descriptive-analytical. In this research, 29 people were interviewed using semi-structured questionnaires and in-depth interviews with urban and passive defense experts. The method of data analysis is quantitative and qualitative. Also, the content analysis method was used to compile and analyze the architectural forms of the stockpile of essential items of essential items compatible with the principles of passive defense. The fuzzy quantitative model IHWP was exploited in GIS software for placing the stockpile of essential items in the studied sample.   Results and discussion Locating From the overlaying of 10 indicators, distance from the fault, height of buildings, distance from gas lines, distance from high voltage power lines, road width, building density, risk of uses, distance from water transmission lines, population density, and land prone to liquefaction, location in 10 class was conducted that the first and second priority is the north-east and south of Mashhad, which has the most favorable location. In Mashhad, 17.2% of the city area has a very low score, 12.8% low score, 48.37% medium score, 20.61% high score, and 0.94% very high score regarding location desirability.   Architecture According to the previous studies on geometric forms, the suitable form for warehouse design is a simple form that does not have frequent breaks and sharp and vague points to reduce the spatial deviation. Among the geometrical shapes, square and rectangular right-cornered shapes meet the criteria of warehouse design. In the meantime, the rectangle can define joints along its length, each of which is a focal point for concentrating activities and organizing their performance. Additionally, the internal spaces in this form are reasonably defined, which results in the building's overall form being overshadowed. This also makes the surrounding accesses more targeted and focused, ultimately providing more suitable relief during times of crisis. In order to create four types of stockpiles of essential items, A (centralized), B (four arms), C (introverted), and D (polar) were designed, and the way of combining these stockpiles of essential items was expressed and analyzed separately. The research results on accesses and circulation shows that type A covers a population of over 100,000 people, which has the best performance in terms of access to exits and spatial organization and provides services in times of crisis. Therefore, type A, due to the sequence of layers, lines, and expansion on the surface, has the most functional symmetry with the body of the warehouse, and its spatial projection is limited to adapt the shell to the body. Visually, it has the least visibility from a high height. Due to its volume and formal indicators, it has a high level of homogeneity and camouflage with its surrounding environment.   Conclusion The results of placing stockpiles of essential items in Mashhad showed that the northeast and south of the city have a higher talent for establishment. According to the examination of geometric forms, the rectangular form has the most efficiency for warehouse design in the architecture area. Due to formal capabilities such as the value of lines, angles, and proportions, it has the most efficiency in terms of performance, motion circulation, and the least spatial deviation. In order to research as mentioned above, after choosing the dominant form of the rectangle, an attempt has been made to analyze the spatial organization of the rectangular form using linear, combined, decomposition, and combination methods and centripetal and radial arrangements in terms of passive defense principles. Furthermore, four different types of warehouse design were formally analyzed as patterns and representative types, which are four arms, centralized, introverted, and diagonal, each of which, in addition to functional capabilities, also covers the population's needs in crisis conditions. Finally, the concentrated type due to the extent of its successive lines and layers in close proximity to each other, the perceptibility of the surfaces of the body joints because it can be recognized from a high altitude in order not to be identified in times of crisis such as air raid, they have the highest degree of compatibility between function and form from the point of view of passive defense.   Funding There is no funding support.   Authors’ Contribution All of the authors approved the content of the manuscript and agreed on all aspects of the work.     Conflict of Interest Authors declared no conflict of interest.   Acknowledgments We are grateful to all the scientific

A question Answering System (QAS) is a special form of information retrieval that consists of three parts: question processing, information retrieval, and answer selection. Determining the type of question is the most important part of QAS as it affects the other following parts. In this work, we use the effective features and ensemble classification in order to improve the QAS performance by increasing the accuracy of question type identification. We use the Gravitational Search Algorithm (GSA) in order to select the features and perform the ensemble classification. The proposed system is extensively tested on different datasets using four types of experiments: (1) neither feature selection nor ensemble classification, (2) feature selection without ensemble classification, (3) ensemble classification without feature selection, and (4) feature selection with ensemble classification. These four kinds of experiments are carried out under the Differential Evolution (DE) algorithm and GSA. The experimental results obtained show that the proposed method outperforms compared to the state-of-the-art methods in the previous research works.

question answering systems are produced and developed to provide exact answers to the question posted in natural language. One of the most important parts of question answering systems is question classification. The purpose of question classification is predicting the kind of answer needed for the question in natural language. The literature works can be categorized as rule-based and learning-based methods. This paper proposes a novel architecture for hybrid classification of questions. The results of the classifiers were combined by five methods of Weighted Voting, Behavior Knowledge space, Naive Bayes, Decision Template and Dempster-Shafer. The method uses a combination of two classifiers based on machine learning (Support Vector Machine and Sparse Representation) and one rule-based classifier. The learning-based classification uses the set of features extracted from the questions. The features are extracted on the basis of the lexical and syntactic structure of the questions. The results from the classifiers were combined by the methods that are common in the combination of one-class classifiers and the Obtained results indicate the improvement of the classification operations in comparison with the present methods.
