坂本 雅志; 藤芳 明生, Corresponding, This paper proposes the use of regular expressions for chemical structure search. As regular expressions dramatically improve the convenience of string search, a regular expression extension for SMILES can improve the convenience of chemical structure search．The regular expression extension for SMILES is obtained from the existing SMILES notation by adding the curly brackets "{" and "}" for range specifications, the vertical bar "|" for enumerations of choices, the asterisk "*" for repetitions of 0 or more times, and the plus"+" for repetitions of 1 or more times. Software for chemical structure search using the extended SMILES was implemented and released., 日本コンピュータ化学会

藤芳 明生; 坂本 雅志, Lead, This paper proposes a substructure search method for finding an element of a set of chemical structures represented by a SMILES string with regular expression extension. It is known that substructure search is an NP-hard problem in general. However, by taking advantage of a graph-theoretical characterization of chemical compounds, the proposed method runs fast enough. Software for substructure search using the proposed method was implemented and released., 日本コンピュータ化学会

藤芳衛; 藤芳明生; 石田透,In order to make it possible for teachers and staff with severely visual disabilities in blind schools and braille publishing companies to produce tactile graphics on their own, by improving the tactile graphics production system Bplot, we developed a new command-line version of Bplot that is specially made for people with severely visual disabilities. The first improvement is that parameters of drawing commands of Bplot can be written in mathematical formulas including variables and functions. Calculations of parameters can be done automatically. The second improvement is that drawing data of graphics can be converted into drawing commands of Bplot. People with severely visual disabilities can use stocks of drawing data to produce tactile graphics by this technology.

日本教育工学会論文誌, May 2017, [Reviewed] - 形式文法を用いて化学構造式中の示性式を自動認識する化学構造式OCRの提案
佐藤文恭; 藤芳明生, Corresponding, 本稿では，形式文法を用いて化学構造式中の示性式を自動認識する方法を提案する．示性式とは，文字のみで構成される化学構造式であり，一般的な化学構造式の一部として現れることがある．そのため，化学構造式OCRを開発するためには，示性式における原子間の結合情報を得る必要がある．従来のOCRアプリケーションでは，事前に示性式の構造を登録した辞書を用いることで，化学構造式画像の認識を行っている．しかし，この方法では辞書に登録されていない示性式は処理することができない．そこで，形式文法を用いて示性式の構文と意味を定義し，示性式の認識を文法の構文解析処理として行うことを提案する．In this paper, we propose a method to recognize condensed structural formulas in chemical structural formulas automatically using a formal grammar. A condensed structural formula is a chemical structural formula that consists of only characters. It appears as a part of general chemical structural formula. Therefore, in order to develop optical chemical structure recognition, we need to obtain the information of bonds between atoms in condensed structural formulas. Conventional optical chemical structure recognition applications use a predefined dictionary which stores the structure of condensed structural formulas. However, condensed structural formulas not stored in the dictionary cannot be processed. So, we define syntax and semantics of condensed structural formulas using a formal grammar and, thus, a recognition of condensed structural formulas can be done as a parsing process of the grammar.

Akio Fujiyoshi; Masakazu Suzuki, Lead, In this paper, we introduce a variation of the minimum spanning tree problem for the application to mathematical OCR. The problem is obtained from the original minimum spanning tree problem by importing the notions of "candidate selection" and "link-label selection." It is shown that the problem is NP-hard. However, we find that, for the application to mathematical OCR, it is sufficient to deal with only a class of graphs that is recursively defined with some graphrewriting rules. For the class of graphs, it is shown that the problem can be solved in linear-time in the number of vertices of a graph., Faculty of Mathematics, Kyushu University
