We show how one can add negation and disjunction to Prolog, with the property that there is no overhead in run time if we do not use the negation, and we only pay for the negation when we actually use it. The extensio...

If one desires that an automatic theory formation program detect inconsistency in a set of hypotheses, the Horn clause logic of Prolog is unsuitable as no contradiction is derivable. Full first order logic provides a ...

The nature of a metalevel extension of Prolog is outlined. The key features include the treatment of theories (databases) and metalevel names as first-class objects which may be the values of variables. The use of the power of these constructs in traditional knowledge representation is explored. In particular, it is shown how frames, semantic nets, scripts, message passing, and non-standard control can be represented.

Computers have been employed within the field of education for many years, often with disappointing results. However, recent and current research within the field of artificial intelligence (AI) is having a positive impact on educational applications. For example, there now exist ICAI (intelligent computer-assisted instruction) systems to teach or tutor many different subjects; several such systems are discussed herein. In addition to CAI (computer-assisted instruction) systems, we discuss the development of learning environments that are designed to facilitate student-initiated learning. A third major application is the use of expert systems to assist with educational diagnosis and assessment. During the course of our discussion of these three major application areas, we indicate where AI has already played a major role in the development of such systems and where further research is required in order to overcome current limitations.

A Fifth-Generation Computer System (FGCS), as usually understood, requires breakthroughs in artificial intelligence and parallel processing. We identify 'near-term' FGCS's relying only on existing developments in hardware, user interfaces, and software techniques integrating databases and a wide range of programming paradigms to achieve much of the social utility expected of FGCS's of the long-term variety. We identify these developments and argue that logicprogramming is too good to be left to the Japanese: that it is an economical basis for a Western near-term FGCS project.

ThisvolumeconstitutestheproceedingsoftheSixthInternationalConferenceon Flexible Query Answering Systems, FQAS 2004, held in Lyon, France, on June 24–26, 2004. FQAS is the premier conference for researchers and practitioners concerned with the vital task of providing easy, ?exible, and intuitive access to information for every type of need. This multidisciplinary conference draws on several research areas, including databases, information retrieval, knowledge representation, soft computing, multimedia, and human-computer interaction. With FQAS 2004, the FQAS conference series celebrated its tenth anniversary as it has been held every two years since 1994. The overall theme of the FQAS conferences is innovative query systems aimed at providing easy, ?exible, and intuitive access to information. Such systems are intended to facilitate retrieval from information repositories such as databases, libraries, and the Web. These repositories are typically equipped with standard query systems that are often inadequate for users. The focus of FQAS is the development of query systems that are more expressive, informative, cooperative, productive, and intuitive to use.

This book constitutes the refereed proceedings of the 21st International Symposium on Methodologies for Intelligent Systems, ISMIS 2014, held in Roskilde, Denmark, in June 2014. The 61 revised full papers were carefully reviewed and selected from 111 submissions. The papers are organized in topical sections on complex networks and data stream mining; data mining methods; intelligent systems applications; knowledge representation in databases and systems; textual data analysis and mining; special session: challenges in text mining and semantic information retrieval; special session: warehousing and OLAPing complex, spatial and spatio-temporal data; ISMIS posters.
