High-speed Detection of Ontological Knowledge and Bi-directional Lexico-Syntactic Patterns from the Web
Hiroaki Ohshima,Katsumi Tanaka
Journal of Software , 2010, DOI: 10.4304/jsw.5.2.195-205
Abstract: We propose a high-speed method of detecting ontological knowledge from the Web. Ontological knowledge in this paper means a term related to a given term. For example, hypernyms and hyponyms are basic related terms that are treated in dictionaries. Synonyms and coordinate terms are also well-defined related terms. Topic terms and description terms represent topics of the given term and they are vaguely defined. There are other related terms such as abbreviations and nicknames. The proposed method can be used for detecting many kinds of related terms. It extracts related terms from text resources only from Web search results, which consist of the titles, snippets, and URLs of Web pages. We use two different kinds of lexico-syntactic patterns to extract related terms from the search results, and these are called bi-directional lexico-syntactic patterns. The proposed method can be applied to both languages where words are separated by a space such as English and Korean and ones where words are not separated by a space such as Japanese and Chinese. The proposed method does not need any advanced natural language processing such as morphological analysis or syntactic parsing. It works relatively fast and has excellent precision. We also propose a method of automatically discovering superior bi-directional lexico-syntactic patterns using Web search engines because it is sometimes difficult to find appropriate patterns to detect related terms in a certain relationship.

Advances in Remote Sensing (ARS) , 2013, DOI: 10.4236/ars.2013.23026

The aim of this research is to apply TerraSAR X-band, Envisat C-band and Palsar L-band synthetic aperture radar (SAR) images for a knowledge acquisition process. For the study, backscattering properties of different natural and man-made objects of urban environment are analyzed on the basis of statistics of signatures of the selected classes. After the knowledge acquisition, for the acquired knowledge representation, a rule-based approach is proposed. Overall, the research demonstrated that the multi-frequency radar images can be effectively used for the knowledge acquisition as well as for the analysis of different land cover types.

A New Algorithm for the Acquisition of Knowledge from Scientific Literature in Specific Fields Based on Natural Language Comprehension  [PDF]
Hui Wei, Zhi-long Dai
International Journal of Intelligence Science (IJIS) , 2011, DOI: 10.4236/ijis.2011.12005
Abstract: The acquisition of knowledge and the representation of that acquisition have always been viewed as the bottleneck in the construction of knowledge-based systems. The traditional methods of acquiring knowledge are based on knowledge engineering and communication with field experts. However, these methods cannot produce systematic knowledge effectively, automatically construct knowledge-based systems, or benefit knowledge reasoning. It has been noted that, in specific professional fields, experts often use fixed patterns to describe their expertise in the scientific articles that they publish. Abstracts and conclusions, for example, are key components of the scientific article, containing abundant field knowledge. This paper suggests a method of acquiring production rules from the abstracts and conclusions of scientific articles in specific fields based on natural language comprehension. First, the causal statements in article abstracts and conclusions are extracted using existing techniques, such as text mining. Next, antecedence and consequence fragments are extracted using causal template matching algorithms. As the final step, part-of-speech-tagging production rules are automatically generated according to a syntax parsing tree from the speech pair sequence. Experiments show that this system not only improves the efficiency of knowledge acquisition but also simultaneously generates systematic knowledge and guarantees the accuracy of acquired knowledge.

Journal of Software Engineering and Applications (JSEA) , 2009, DOI: 10.4236/jsea.2009.25041
Abstract: In the Chinese character intelligent formation system without Chinese character library, it is possible that the same basic element in different Chinese characters is different in position, size and shape. The geometry transformation from basic elements to the components of Chinese characters can be realized by affine transformation, the transformation knowledge acquisition is the premise of Chinese character intelligent formation. A novel algorithm is proposed to ac-quire the affine transformation knowledge of basic elements automatically in this paper. The interested region of Chi-nese character image is determined by the structure of the Chinese character. Scale invariant and location invariant of basic element and Chinese character image are extracted with SIFT features, the matching points of the two images are determined according to the principle of Minimum Euclidean distance of eigenvectors. Using corner points as identifi-cation features, calculating the one-way Hausdorff distance between corner points as the similarity measurement from the affine image to the Chinese character sub-image, affine coefficients are determined by optimal similarity. 70244 Chinese characters in National Standards GB18030-2005 character set are taken as the experimental object, all the characters are performed and the experimental courses and results are presented in this paper.

Leveraging Framework Documentation Solutions for Intermediate Users in Knowledge Acquisition
International Journal of Information Science , 2013, DOI: 10.5923/j.ijis.20130301.03
Abstract: Frameworks are increasingly employed as a useful way to enable object-oriented reuse. However, understanding frameworks is not easy due to their size and complexity. Previous work concentrated on different ways to document frameworks, but it was unclear which ones actually were better. This paper presents a novel way of investigating the different philosophies for framework documentation. The philosophies include minimalist, patterns-style and extended javadoc (Jdoc) documentation. Using a survey of 90 intermediate users engaged in Command and Adaptor design patterns coding work, this exploratory study discovered that minimalist documentation has positive impacts in encouraging knowledge acquisition, significantly in terms of the framework functional workings. This concludes that documentation solutions with the minimalist principle can lead intermediate users to faster growth in learning two of the design patterns.

Abstract: this study analyzed the acquisition of word spelling strategies in spanish-speaking children, during the first two years of elementary education. the cognitive word spelling models, initially developed for english, describe different stages in the acquisition spelling process. in the first stage, children write by memory, reproducing visual cues. at a second stage, children analyze the phonological structure of the word. finally, in an orthographic stage, children can write words, using lexical information, without phonological mediation (frith, 1984, 1985; marsh, friedman, welch & desberg, 1980). even when the stages theory was discussed, these first studies allowed the identification of early lexical strategies and phonological mechanisms implied in the english word spelling processes. however, english is a language with a deep orthography, and the phonological strategy is a necessary mechanism but it is not enough to spell words properly. on the contrary, the spanish orthographic system is shallow, and the phonemes-graphemes correspondences are very regular. consequently, the spelling strategies could be different in these two languages, and the models developed for english would partially explain the orthographic learning process in transparent languages. this work aims to contribute to the knowledge on early spelling word strategies in spanish. in two experiments, first and second grade children were given spelling tests designed to explore their phonological and orthographic knowledge. in the first experiment, the incidence of word complexity, length and frequency on spelling performance was explored. however, there was a possibility that, if children performed better in frequent words spelling, in relation to less frequent, they were resorting to their lexical knowledge. in this case, children were using an orthographic-lexical strategy. on the other hand, the possibility of writing complex and long words is associated to the phonological awareness level and
