Answer the following question: Information:  - A programming language is a formal computer language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.  - Artificial intelligence (AI) is intelligence exhibited by machines. In computer science, an ideal "intelligent" machine is a flexible rational agent that perceives its environment and takes actions that maximize its chance of success at some goal. Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving". As machines become increasingly capable, mental facilities once thought to require intelligence are removed from the definition. For example, optical character recognition is no longer perceived as an exemplar of "artificial intelligence", having become a routine technology. Capabilities currently classified as AI include successfully understanding human speech, competing at a high level in strategic game systems (such as Chess and Go), self-driving cars, and interpreting complex data. Some people also consider AI a danger to humanity if it progresses unabatedly.  - Prolog is a general-purpose logic programming language associated with artificial intelligence and computational linguistics.  - Programming paradigms are a way to classify programming languages according to the style of computer programming. Features of various programming languages determine which programming paradigms they belong to; as a result, some languages fall into only one paradigm, while others fall into multiple paradigms. Some paradigms are concerned mainly with implications for the execution model of the language, such as allowing side effects, or whether the sequence of operations is defined by the execution model. Other paradigms are concerned mainly with the way that code is organized, such as grouping code into units along with the state that is modified by the code. Yet others are concerned mainly with the style of syntax and grammar.  - Carcassonne  is a fortified French town in the Aude department, of which it is the prefecture, in the Region of Occitanie.  - Datalog is a declarative logic programming language that syntactically is a subset of Prolog. It is often used as a query language for deductive databases. In recent years, Datalog has found new application in data integration, information extraction, networking, program analysis, security, and cloud computing.  - Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.  - A computer scientist is a scientist who has acquired the knowledge of computer science, the study of the theoretical foundations of information and computation and their application.  - Logic programming is a type of programming paradigm which is largely based on formal logic. Any program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain. Major logic programming language families include Prolog, Answer set programming (ASP) and Datalog. In all of these languages, rules are written in the form of "clauses":  - Aude is a department in south-central France named after the river Aude. The local council also calls the department "Cathar Country". Aude is also a frequent feminine French given name in Francophone countries, deriving initially from Aude or Oda, a wife of Bertrand, Duke of Aquitaine, and mother of Saint Hubertus's brother Eudo. Aude was the name of Roland's fiancée in the chansons de geste.  - Answer set programming (ASP) is a form of declarative programming oriented towards difficult (primarily NP-hard) search problems. It is based on the stable model (answer set) semantics of logic programming. In ASP, search problems are reduced to computing stable models, and "answer set solvers"  programs for generating stable modelsare used to perform search. The computational process employed in the design of many answer set solvers is an enhancement of the DPLL algorithm and, in principle, it always terminates (unlike Prolog query evaluation, which may lead to an infinite loop).  - Alain Colmerauer ( born 24 January 1941 , Carcassonne ) is a French computer scientist and the creator of the logic programming language Prolog .  - Computational linguistics is an interdisciplinary field concerned with the statistical or rule-based modeling of natural language from a computational perspective.    After reading the paragraphs above, choose the best answer for the entity that related to 'alain colmerauer' with the relationship of 'field of work'.  Choices: - artificial intelligence  - computer programming  - computer science  - computing  - declarative programming  - french  - information  - information extraction  - language  - linguistics  - logic  - programming language  - river  - science  - scientist
