Accurate proofreading Interface requires resolving the ambiguity that occurs when the system determines the relations between the free-form by the user and editing scopes of the document. Proofreading for structure documents such as XML/XHTML involves modification of document structures and modified document also should follow the pre-defined DTD. This paper present a CPI (Context-based Proofreading Interface) based on the XML. The CPI supports free-form drawing of correction marks and provides context-based scope recognition and revision methods. CPI provides both implicit and explicit modification methods for document structures. As a result, the correction mark information produced in this paper includes more accurate scope information than that in other systems.

In this study, we constructed a biological system that exhibited thermotolerance, ethanol tolerance, and increased ethanol productivity using a random mutagenesis method. We attempted to isolate a thermotolerant mutant using proofreading-deficient DNA polymerase ${\delta}$ and ${\varepsilon}$ encoded by the pol3 and pol2 genes, respectively, in Saccharomyces cerevisiae. To obtain mutants that could grow at high temperatures ($38^{\circ}C$ and $40^{\circ}C$), random mutagenesis of AMY410 (pol2-4) and AMY126 (pol3-01) strains was induced. The parental strains (AMY410 and AMY126) grew poorly at temperatures higher than $38^{\circ}C$. By stepwise elevation of the incubation temperature, AMY410-Ht (heat tolerance) and AMY126-Ht strains that proliferated at $40^{\circ}C$ were obtained. These strains were further incubated in medium containing 6% and 8% ethanol and then AMY410-HEt (heat and ethanol tolerance) and AMY126-HEt strain with ethanol tolerance at an 8% ethanol concentration was obtained. The AMY126-HEt strain grew even at an ethanol concentration of 10%. Furthermore, following the addition of high concentrations of glucose (5% and 10%), an AMY126-HEt3 strain with increased ethanol productivity was isolated. This strain produced 24.7 g/l of ethanol (95% theoretical conversion yield) from 50 g/l of glucose. The findings demonstrate that a new biological system (yeast strain) showing various phenotypes can be easily and efficiently bred by random mutagenesis of a proofreading- deficient mutant.

Offshore software development (OSD) is international business collaboration. OSD projects often encounter intercultural and inter-linguistic problems disturbing the projects. Business documents are formal media of information and knowledge for OSD. While OSD documents should convey common understanding of the OSD products, the documents may contain unsuitable expressions which draw misunderstanding of the required products and offensive issues for the collaboration. Intercultural and inter-linguistic differences cause mistakes and inappropriate expressions. OSD from Japan to China is the largest in Asia, and Japanese language is often used in OSD documents. Large similarity is found between Japanese and Chinese in their languages, while many differences exist even for the same word. The similarity induces to write unsuitable expressions for both sides of OSD. To introduce risks for OSD projects caused by unsuitable or inappropriate expressions in OSD documents, we propose to apply a proofreading system of Japanese documents for OSD. Japanese consignor uses the system to refine OSD documents written by Japanese engineers for Chinese readers, and Chinese consignee uses it to refine Japanese documents written by Chinese Engineers as derivatives of OSD projects. Effectiveness of applying the proofreading system is discussed for actual projects.

The thermotolerant methylotrophic yeast Hansenula polymorpha is attracting interest as a potential strain for the production of recombinant proteins and biofuels. However, only limited numbers of genome engineering tools are currently available for H. polymorpha. In the present study, we identified the HpPOL3 gene encoding the catalytic subunit of DNA polymerase ${\delta}$ of H. polymorpha and mutated the sequence encoding conserved amino acid residues that are important for its proofreading 3'${\rightarrow}$5' exonuclease activity. The resulting $HpPOL3^*$ gene encoding the error-prone proofreading-deficient DNA polymerase ${\delta}$ was cloned under a methanol oxidase promoter to construct the mutator plasmid pHIF8, which also contains additional elements for site-specific chromosomal integration, selection, and excision. In a H. polymorpha mutator strain chromosomally integrated with pHIF8, a $URA3^-$ mutant resistant to 5-fluoroorotic acid was generated at a 50-fold higher frequency than in the wild-type strain, due to the dominant negative expression of $HpPOL3^*$. Moreover, after obtaining the desired mutant, the mutator allele was readily removed from the chromosome by homologous recombination to avoid the uncontrolled accumulation of additional mutations. Our mutator system, which depends on the accumulation of random mutations that are incorporated during DNA replication, will be useful to generate strains with mutant phenotypes, especially those related to unknown or multiple genes on the chromosome.

Till now, Korean spelling proofreading system has corrected words of a sentence from the relationship of a collocation or the grammatical information of the sentence. In this paper, we propose a system that corrects a word using the relationship among the sememes in a single sentence and substitutes an apt word for a word of the sentence that has the meaningful mistake by a mistyping. The proposed system makes several sentences that are able to communicate with each sememe. The substantives forms meaning tree according to the meaning of the word and the predicate of a sentence defines the meaningful relationship between a substantives of the subject and the object. After this system compares and analyzes the relationship of meaning, it corrects the mistyping of a word in a single sentence that includes an error. If the system finds out the semantic error by the mistyping, it applies the spelling proofreading method that proposed in this paper.

Typographical mistakes made in the writing process of drafts of electronic documents are more common than any other type of errors. The majority of these errors caused by mistyping are regarded as consequently still typo-errors, but a considerable number of them are developed into the grammatical errors and the semantic errors. Pseudo semantic errors among these errors due to typographical errors have more noticeable peculiarities than pure semantic errors between senses of surrounding context words within a sentence. These semantic errors can be detected and corrected by simple algorithm based on the co-occurrence frequency because of their prominent contextual discrepancy. I propose a method for detection and correction based on the co-occurrence frequency in order to detect semantic errors due to typo-errors. The co-occurrence frequency in proposed method is counted for only words with immediate dependency relation, and the cosine similarity measure is used in order to detect pseudo semantic errors. From the presented experimental results, the proposed method is expected to help improve the detecting rate of overall proofreading system by about 2~3%.

The purpose of this study is to examine the establishment and development of Daesoon Thought Thesaurus. Specifically, this study examined the matters to be considered in the stage of Thesauri planning according to the Thesauri Construction process : presents the methods and standards of Thesauri Construction according to processes such as identification of the indexing policy, establishment of Thesauri system, collection of vocabulary, selection of preferred term, clustering of the terms, establishment of term relationships, overall adjustment, Thesauri test, proofreading by professional display, maintenance and updating. Since religion information is unique or totally different from the information in other areas, it is most important to construct the Thesauri suitable for system after carefully recognizing the concept of religion terms.
