In this work, we generalise the categorical syllogistic logic in several dimensions to a relatively expressive logic that is sufficiently powerful to encompass a wider range of linguistic semantics. The generalisation is necessary in order to eliminate the existential ambiguity of the quantifiers and to increase expressiveness, practicality, and adaptivity of the syllogisms. The extended semantics...
This paper introduces five similarity measures, very well known in literature, but not because of using them to compare rules between themselves and choose the most similar one. Rules in knowledge bases are a very specific type of data representation and it is necessary to compare them carefully. The goal of the paper is to analyze the influence of using different similarity measures on the number...
Providing financial e-services in the all areas involves taking decisions processes. Existing systems, also multi-agent systems, usually include only one of the earlier mentioned areas, and they are closed systems, available only to a small group of users. In addition, agents' knowledge in these systems is characterized by a certain degree of heterogeneity. Since in the decisive process one final...
The BDI (Beliefs, Desires, Intentions) architecture is commonly used for the development of systems of agents situated in complex and dynamic environments. The BDI architecture represents a consolidated model that counts upon substantial theoretical and practical contributions. However, despite the strengths of symbolic models, there are some aspects of the cognitive phenomena that give rise to the...
With the appearance of Web 2.0 technologies, the way Internet is conceived has dramatically changed. Internet users have begun to perform a more active role in providing and sharing the information available on the Web. Thanks to mobile technologies, users can access the Internet from their smartphones at any time, independently of their location. Moreover, users gather in communities where they can...
A paper is concerned with a static decision (control) plant described by a relation with two kinds of unknown parameters: uncertain parameters described by certainty distributions and random parameters described by probability distributions. Different versions of the decision making in an open-loop control system are formulated and considered. A simple example illustrates the presented approach.
The gradual increase of cancer cases worldwide has been posing a need on the use of computing resources to accurately retrieve the information recorded in databases. One can highlight the retrieved information importance from a specialist in order to better evaluate pathological response and predict the cancer patient prognosis. This paper presents a way to represent knowledge of cancer registries...
Planning suitable menus for individuals who have health problems is a complex task since the solutions produced by professionals (dietitians) are usually very subjective and difficult to be systematically represented. This research focused on designing the knowledge base repository construction which consists of the existing cases to be used as the case-based for the retrieval process. The main aim...
To solve the vagueness and randomness of knowledge representation in the process of decision-making analysis of equipment support system assessment, the paper applies cloud theory to build valuation model. According the analysis about the equipment support system, the input and output parameter of valuation is defined, and the concept subsets are also designed. Based on the research on the cloud theory,...
In product design process, Cost reduction is a complex solution procedure based on knowledge reasoning. Scientific knowledge representation is the basis of the logical consequence. Begin with expatiating the components and characteristic of the whole lifecycle cost of mechanical product, this paper analyses the characteristic of cost reduction knowledge, on which basis, it presents the frame knowledge...
With rough set theory, the study area is divided into regular grid cells, landslide hazard assessment indexes system and geohazards knowledge representation system and decision table in study area are designed. On this basis, specific algorithms for assessment indexes system optimization and weights confirmation are constructed. So that landslide hazard quantitative scores are calculated,and landslide...
Ontology construction is closely related to semantic networks and artificial intelligence; it has broad prospects in knowledge reuse and share, just becoming mainstream of professional knowledge base construction. This study takes ontology-based triad representation into criminology knowledge base construction. It puts forward "three bases & four layers" model of criminology knowledge...
The competitiveness of service enterprise is related to the competitiveness of the whole service industry, and affects the development of country's economics and society. Based on the three meanings of the competitiveness of enterprises, this paper defines the content of the competitiveness of service enterprise, which including business resources, entrepreneurial capabilities and business performance...
In this paper, we focus on two questions common in tunneling project:(i) how to identify the unmeasured stratum; (ii) how to make the project safe under the uncertain condition automatically. The basic ideal of the presented approach is to establish a soil identification model with statistical information of geological site investigation and then to update the model with Field Penetration Index (FPI)...
This paper introduces connectionistic concept grid (CCG), which is used for representation and reasoning of engineering knowledge applied for the industrial systems. The paper also presents the Crossword tool which was used for computer aided modelling and execution of CCG. CCG is able to provide semantic descriptions of objects and processes and was developed to overcome limitations of earlier knowledge...
Credibility evaluation process is a process in which the credibility values of each index are integrated, and total credibility value of simulation system is evaluated based on its evaluation indexes. Because of different methods used in VV & A process, VV & A results may be quantitative or qualitative. In this paper, a credibility evaluation method based on Cloud Model is brought forward,...
A natural movement towards artificial intelligence (AI) techniques took place in the last years in power system analysis. Many research works have used AI topics like search techniques, knowledge representation, reasoning and learning systems, as well as heuristic tools to address power system problems. This paper focuses the discussion on power system reliability evaluation and this natural transition...
Co-authored documents are becoming increasingly important for knowledge representation and sharing. Tools for supporting document co-authoring are expected to satisfy two requirements: 1) querying changes over editing histories; 2) maintaining data consistency among users. Current tools support either limited queries or are not suitable for loosely controlled collaborative editing scenarios. We address...
SAX is the representative time series representation method. SAX used the PAA technique to reduce the dimension of time series. But PAA technique has the demerit that cannot represent various movement shapes of time series exactly in lower dimensional space, since its smoothing effect distorts the dynamic characteristic of time series. Therefore, this paper suggests new representation method of time...
Many previous researchers have converted background knowledge as constraints to obtain accurate clustering. These clustering methods are usually called constrained clustering. Previous ordering constraints are instance level non-hierarchical constraints, like must-link and cannot-link constraints, which do not provide hierarchical information. In order to incorporate the hierarchical background knowledge...
