The development of computers and network environments has been accompanied with the increase of data stored electrically. The importance of inductive learning methods, which discover knowledge from data, is more increasing. The paper focuses on a representative inductive learning method, 1D3, which acquires a rule set described by a decision tree, and discusses relations between 1D3, other inductive learning methods, and fuzzy inductive learning methods. Lastly, the paper introduces current topics in related study fields and shows future directions of fuzzy inductive learning fields.

This paper describes a transformation of the Cognitive Walkthrough (CW), a theory-based usability inspection method that has proven useful in designing applications that support use by exploration. The new Cognitive Walkthrough for the Web (CWW) is superior for evaluating how well websites support users' navigation and information search tasks. The CWW uses Latent Semantic Analysis to objectively estimate the degree of semantic similarity (information scent) between representative user goal statements (100-200 words) and heading/link texts on each web page. Using an actual website, the paper shows how the CWW identifies three types of problems in web page designs.

This paper proposes an utterance generation model for systems that provide information via spoken dialogues. The information source is web sites on the Internet. The role of utterances in such systems is to provide information to users in an intuitively understandable form. Since the information on web sites is uncertain and inconsistent, the system has to acquire and integrate information from multiple sources in order to improve the reliability of information and generate utterances reflecting the reliability of the information. In our model, utterances are generated through two phases. The first phase integrates information acquired from multiple sources. The second phase generates linguistic expressions that reflect the reliability of integrated information. In this paper, we use the example of a weather forecast information system. This system gathers and integrates information from several weather forecast sites and then answers a user's question via dialogue.

Web information visualization method based on the metaphor of immune network model is proposed to handle the set of documents obtained from the Web, such as retrieval results and online news articles. In order to achieve the effective browsing as well as to grasp the topic distribution through the document set, both the keyword map (a space on which keywords are arranged based on the co-occurrence) and the document clustering are generated in synthetic manner. The proposed method is based on the keyword extraction with using the activation mechanism of the immune network model, while the activation state of the network is also useful as a metaphor to improve the readability of the keyword map. Experimental results show that the document clusters covering about 70% of the document set without overlapping can be generated by the proposed method. The questionnaires are also issued to evaluate the proposed method from the viewpoint of topic representation, and the proposed method can get better results than k-means clustering, for 2 of 3 data sets. Furthermore, it is also shown that the topic-sensitive keyword map can be constantly obtained by introducing the immune network metaphor.

In this paper, we propose and implement a user support system for UNIX interface based on prediction of command-line. The proposed system can predict a command and the arguments independently using prediction rules extracted from the user's command-line history in real time. In order to predict next command-line, the proposed system pays attention to contexts of the history and relations depending on command-to-arguments. This system needs no knowledge about commands in advance, because it can extract the prediction rules from the history. The prediction process is implemented as the repetition of the following phases: input phase, prediction phase, computation phase, and updating phase. By repeating the process, the system can extract rules for the user and can adapt itself to various situations. We have compared the proposed system with FRQ and LRU method using actual command-line history, and obtained excellent results.

This paper proposes a new communication protocol, called a language protocol, and a new communication method using the protocol. They are developed as fundamental technologies of everyday language computing in which human intellectual activities by natural language is realized on a computer. In the framework for the proposed technologies, we show a flexible communication among any communication object is achieved by the proposed technologies. The availability of the proposed technologies is verified by a simulation example of the communication method using the language protocol.

In order to develop a multi-agent system, we must decide values of the system parameters. The system parameters are classified into user's parameters and designer's parameters. The user's parameters are decided by the user's intention, and the designer's parameters are decided by the system designer to construct the effective agent systems. We developed a contract simulator for apartment houses and examined the system parameter's influence on the effect of the agent system using the contract simulator. We discuss the effect of the contract system when one agent can enter a ballot for several apartment houses.

A general model of information retrieval in which a variety of methods of retrieval is incorporated is proposed. The methods include the classical logical model, fuzzy logical model, algebraic models such as the vector model, learning in retrieval, associative retrieval, information filtering, and a new model of fuzzy multisets. The present model is capable of constructing a new method of information retrieval by using a new algebraic or logical structure.
