Opis:
Bilingual code-mixed (hybrid) languages have become very popular in India as a result of the spread of technology in the form of television, the Internet, and social media. Due to this increase in the use of code-mixed languages in day-to-day communication, the need for maintaining the integrity of the Indian languages has arisen. As a result of this, a tool named Hinglish to Pure Hindi and English Translator was developed. The tool is capable of translating in three ways; namely, Hinglish into pure Hindi and English, pure Hindi into pure English, and vice versa. The tool has achieved an accuracy of 91% in giving Hindi sentences and of 84% in giving English sentences as output when the input sentences were in Hinglish. The tool has also been compared with another similar tools.

Opis:
Rules are one of the most important knowledge representation methods. Rule-based expert systems proved to be a successful AI technology in a number of areas. Building such systems requires creating a rule-base, as well as providing an effective inference mechanism that fires rules appropriate in a given context. Building and maintaining such a rule-base is a very difficult task and can be supported by a sepcially designed tools. Due to the fact that inference engines usually are parts of such tools it is difficult to integrate such expert systems with external software. In this paper a custom inference engine was presented, that implements three inference algorithms and can be easily integrated with other systems. Its usage in selected intelligent systems was also described.
Reguły są jedną z najważniejszych metod reprezentacji wiedzy. Systemy ekspertowe oparte na regułowej bazie wiedzy są istotną technologią w zastosowaniach sztucznej inteligencji w różnych dziedzinach. Budowanie takich systemów wymaga stworzenia bazy wiedzy, jak również dostarczenia wydajnego mechanizmu pozwalającego na uruchamianie reguł i wnioskowanie. Budowanie bazy wiedzy i zarządzanie nią jest bardzo trudnym zadaniem. Może ono być wspierane poprzez narzędzia przeznaczone do tego celu, jednak ponieważ silniki wnioskujące zazwyczaj stanowa integralną część takich narzędzi, integracja ich z zewnętrznym oprogramowanie stanowi jeszcze trudniejsze zadanie. W niniejszym artykule opisany został nowy regułowy silnik wnioskujący, pozwalający na stosowanie kilku algorytmów wnioskowania i łatwą integrację z innymi systemami. Przedstawione zostało również jego zastosowanie w wybranych inteligentnych systemach komputerowych.

Opis:
Rule languages and inference engines incorporate reasoning capabilities to Web information systems. This paper presents an approach for the specification and development of Web applications performing the usual functionalities of data management and incorporating a rule engine for reasoning capabilities. The proposed approach is based on the definition of a high-level representation of the semantics of rule-based applications through a formalism for conceptual modeling combining lightweight ontologies and production rules. These models are used as the source for a model-driven method that applies several transformations to conceptual models generating the rule-based Web application code in an automatic process. As a result, the rule-based Web application embeds a rule engine suitable for deducing information by applying an inference process. The structure of the information managed by the Web application is based on ontology classes, whereas the logical expressions applied in reasoning are obtained from production rules of the model. A rule-based Web application has been developed and evaluated using a supporting tool that implements the ideas presented in this paper.

Opis:
Electronic waste generated from Information and Communication Technologies (ICT) has become a global issue as this represents a negative impact on both environment and human health. Consequently, it is noticeably useful to develop tools to soften such impact. Therefore, this article presents a rules-based system implemented in Prolog aiming at guiding ICT devices users towards good practices on electronic waste management to diminish the negative impact. The methodologies employed include exploratory, descriptive, and experimental. Even though the system developed in Prolog was found to be deficient with user interface, it is also functional and efficient, including features like usability and maintainability. In conclusion, it was found that waste recollection systems may be useful for both environmental management processes in different countries and also positive business opportunities.

Opis:
The paper addresses several open problems regarding the automatic design of fuzzy rule-based systems (FRBSs) from data using multi-objective evolutionary optimization algorithms (MOEOAs). In particular, we propose: a) new complexity-related interpretability measure, b) efficient strong-fuzzy-partition implementation for improving semantics-related interpretability, c) special-coding-free implementation of rule base and original genetic operators for its processing, and d) implementation of our ideas in the context of well-known MOEOAs such as SPEA2 and NSGA-II. The experiments demonstrate that our approach is an effective tool for handling FRBSs’ accuracy-interpretability trade-off, i.e, designing FRBSs characterized by various levels of such a trade-off (in particular, for designing highly interpretability-oriented systems of still competitive accuracy).

Opis:
This paper presents a new root-extraction approach for Arabic words. The approach tries to assign for Arabic words a unique root without relying on a database of word roots, a list of word patterns or a list of all the prefixes and the suffixes of the Arabic words. Unlike most of Arabic rule-based stemmers, it tries to predict the root-letters positions one by one based on some rules and relations among the word letters and their placement in the word. This paper focuses on two parts of the approach. The first one introduces some rules to distinguish between the Arabic definite article and the permanent component that may found in any Arabic word. The second one classifies Arabic letters in to groups according to their positions in the word. The proposed approach is a system composed of several modules used to extract the word root. The approach has been evaluated using the Holy Quran words. The evaluation results show a promising root extraction algorithm.

Opis:
In the paper an algorithm for automatic knowledge acquisition is proposed. The knowledge is acquired from aggregate data stored in different repositories. The algorithm operates by means of semantic data integration, allowing both syntax and semantic differences between data coming from different sources. If only we know data taxonomies, can interpret data schemas and design schema mappings, then the differences are not an obstacle to integration. The acquired knowledge is being defined in a form of production rules with uncertainty. The considerations are illustrated with medical examples.

Opis:
Although the first rule-based systems were created as early as thirty years ago, this methodology of expert systems designing still proves to be useful. It becomes especially important in medical applications, while treating evidence given in an electronic format. Constructing the knowledge base of a rule-based system and, especially, of a system with uncertainty is a difficult task because of the size of this base as well as its heterogeneous character. The base consists of facts, ordinary rules and meta-rules, which differ from each other regarding both the syntax structure and the semantics. Having no tool to aid designing and maintaining the knowledge base of a rule-based system with uncertainty, we propose the algebra of rules with uncertainty which gives us theoretical foundations to build such a tool. Using the tool, it will be possible to indicate the facts and rules of a redundant character, as well as the pairs of facts and the pairs of rules which are contradictory to each other. The above tool is used in designing and maintaining the knowledge base of a system intended to prognosticate the effects of a medical treatment of the bronchial asthma disease.

Opis:
In the presented work two variants of the fuzzy clustering approach dedicated for determining the antecedents of the rules of the fuzzy rule-based classifier were presented. The main idea consists in adding additional prototypes (’prototypes in between’) to the ones previously obtained using the fuzzy c-means method (ordinary prototypes). The ’prototypes in between’ are determined using pairs of the ordinary prototypes, and the algorithm based on distances and densities finding such pairs was proposed. The classification accuracy obtained applying the presented clustering approaches was verified using six benchmark datasets and compared with two reference methods.

Opis:
Indoor scene classification forms a basis for scene interaction for service robots. The task is challenging because the layout and decoration of a scene vary considerably. Previous studies on knowledge-based methods commonly ignore the importance of visual attributes when constructing the knowledge base. These shortcomings restrict the performance of classification. The structure of a semantic hierarchy was proposed to describe similarities of different parts of scenes in a fine-grained way. Besides the commonly used semantic features, visual attributes were also introduced to construct the knowledge base. Inspired by the processes of human cognition and the characteristics of indoor scenes, we proposed an inferential framework based on the Markov logic network. The framework is evaluated on a popular indoor scene dataset, and the experimental results demonstrate its effectiveness.

Opis:
This paper proposes the usage of the fuzzy rule-based Bayesian algorithm to determine which residential appliances can be considered for the Demand Response program. In contrast with other related studies, this research recognizes both randomness and fuzziness in appliance usage. Moreover, the input data for usage prediction consists of nodal price values (which represent the actual power system conditions), appliance operation time, and time of day. The case study of residential power consumer behavior modeling was implemented to show the functionality of the proposed methodology. The results of applying the suggested algorithm are presented as colored 3D control surfaces. In addition, the performance of the model was verified using R squared coefficient and root mean square error. The conducted studies show that the proposed approach can be used to predict when the selected appliances can be used under specific circumstances. Research of this type may be useful for evaluation of the demand response programs and support residential load forecasting.

Opis:
This paper will analyze the impact of the modernized approach to Article 102 TFEU on the application of the prohibition of dominant position abuse contained in Polish competition law. For that purpose, several questions will be answered. Has the consumer-welfare standard already become, or will it become (in particular under the influence of the effects-based approach), the decisive criteria for the finding of a violation of Article 9 of the Polish Competition Act as well as its past equivalents? Will EU’s new approach to the abuse of dominance lead to a re-orientation of the goals pursued by Polish competition law on unilateral conduct? Has Polish enforcement practice attached as much emphasis to the protection of market structures as some EU cases that might have justified the accusation of over-enforcement? Has the recent reform introduced any new requirements, standards or tests in the procedural dimension of the application of the ban on the abuse of dominance and if so, to what an extent will they influence the traditional approach employed by Polish antitrust and judiciary institutions? In order to answer these questions, relevant Polish legislation and case-law will be analyzed. The article will try to establish the actual scope of the change relating to substantive as well as procedural rules which will (or should) affect the enforcement of Article 9 of the Polish Competition Act under the impact of the new EU approach.
Cet article a pour but d’analyser l’impact de l’interprétation modernisée de l’article 102 TFUE sur l’application de l’interdiction de l’abus de position dominante dans la loi polonaise. Dans ce but, nombreuses questions seront adressées. Par exemple, le bien être des consommateurs, est-il déjà, ou sera-t-il dans le future (en particulier, sous l’influence de l’approche fondée sur les effets), le critère décisif pour constater une violation de l’article 9 du Droit de la concurrence polonais, aussi que leurs équivalents? La législation polonaise et la jurisprudence seront analysées. Cet article tente d'établir l'étendue actuel des changements relatifs aux règles substantives et procédurales, qui affectent (ou devraient affecter) le renforcement de l’article 9 du Droit de la concurrence polonais sous l’influence de la nouvelle approche de l’UE.
