An intermediary expert system (IES) helps both end users and professional searchers to conduct their online database searching. To provide advice about term selection and query expansion, an IES should include a terminological knowledge structure. Terminological attributes as well as other properties could provide the starting point for building a knowledge base, and knowledge acquisition could...

Most existing visual analytical tools that incorporate knowledge are tailored for specific analytical tasks. Although these tools are useful and powerful, it is often difficult to generalize the approaches utilized in these tools for knowledge incorporation to new problems or domains. In this paper, we propose a method for integrating a visual analytical tool with an ontological knowledge struc...

V isualizing the entire body of scientific knowledge and tracking the latest developments in science and technology have intrigued generations of scientists, philosophers, government officials, librarians, and publishers. Advances in information visualization offer promising tools for presenting knowledge structures and their development in an increasingly intuitive way. 1 The scientific litera...

The analysis of a document image to derive a symbolic description of its structure and contents involves using spatial domain knowledge to classify the different printed blocks (e.g., text paragraphs), group them into logical units (e.g., newspaper stories), and determine the reading order of the text blocks within each unit. These steps describe the conversion of the physical structure of a do...

We have developed an automatic algorithm STRIDE for protein secondary structure assignment from atomic coordinates based on the combined use of hydrogen bond energy and statistically derived backbone torsional angle information. Parameters of the pattern recognition procedure were optimized using designations provided by the crystallographers as a standard-of-truth. Comparison to the currently ...

Intelligent Topic Map (ITM) embodies the multilevel, multi-granularity and the inherent relevant characteristics of knowledge. With ITM as infrastructure, this paper presents a visual knowledge structure reasoning method integrates the logic-based knowledge reasoning and the structure-based knowledge reasoning. The logic-based knowledge reasoning implements knowledge consistency checking and th...

molecular understanding of three-dimensional (3d) peptide: mhc models require both basic knowledge of computational modeling and skilled visual perception, which are not possessed by all students. the present model aims to simulate mhc molecular structure with the hands and make a profound impression on the students.

We examine two major perspectives in the literature on domain specificity in cognition: in one of them cognitive modules are “intuitive theories”; in the other they are dispositional structures. Both of these positions accept that there is a continuous line from ordinary to scientific reasoning; nevertheless they interpret this continuity differently. We propose an alternative way of understand...
