    As products become large-scale and complex, manufacturing industry faces problems in communication between workers. Among the information to be communicated, design rationale, such as reasons for decided design and the process of consideration leading to the decisions, is rarely expressed in shared design data. This paper proposes a information extraction method of design rationale. While design are conducted, conversations are recorded. Recorded sounds are transcribed using the voice input functions in Google Docs. The transcribed data is analyzed by TF/IDF, which evaluates importance of each word in the script by its frequency and rarity. By extracting sentences that contains important words, it is assumed that most design rationales can be depicted. The proposed method was applied to the design of scissors. The case shows that the proposed method has potential for extracting design rationale.

    Authors: Kondō, Kōshi;

    This invited paper provides a detailed essay on the history of gamebooks in Japan from the 1980s to the 1990s. It discusses the impact of the gamebook The Warlock of Firetop Mountain (Jackson & Livingstone, 1982) and how it revolutionized the concept of readers making choices that determine the outcome of the story. The essay also touches on the various genres that gamebooks have covered, the establishment of the term “gamebook” in Japan, and the cultural significance of this interactive form of storytelling. It mentions the rise and fall of the gamebook trend in Japan, including the publication of a dedicated magazine “Warlock” and the shift of focus to tabletop RPGs post the gamebook boom. 80年代から90年代にかけて日本で流行したゲームブックについてのエッセイである.読者が物語の結末を決定する選択をするという概念に革命を起こした『火吹山の魔法使い』(ジャクソン&リビングストン,1982,日本語版 1984)がどのようにジャンルを確立したかを論じる.また,ゲームブックがカバーしてきた様々なジャンル,日本における「ゲームブック」という用語の定着,このインタラクティブな物語形式の文化的意義にも触れている.専門誌「ウォーロック」の創刊や,ゲームブックブーム後のテーブルトークRPGへの移行など、日本におけるゲームブックの盛衰にも考察している. 本文ファイルを差し替え(2024-01-16)

    Authors: Matsuda, Mana; Tsuda, Hiroshi;

    Due to the development of natural language processing technologies, the effectiveness of text-based investment strategies for stocks has been demonstrated. Focusing on quarterly financial statements, the polarity of the text is often quantified and used for investment strategies. In this study, we quantified the detailed content of quarterly financial statements by using Sentence-BERT to create features and we were able to find features which have higher interpretability on stock price fluctuations from many companies' quarterly financial statements compared to regression analysis. Therefore, we found that decision tree regression can realize the non-linear patterns between the content of quarterly financial statements and stock price fluctuation. 自然言語処理技術の発展に伴い、テキストを用いた株式の投資戦略の有効性が示されつつある。決算短信に注目すると、テキストの極性を定量化し、投資戦略に用いることが多い。本研究では、Sentence-BERTで決算短信の詳細な内容を定量化して特徴量を作成し、株価変動に対して決定木を用いた回帰を行った。その結果、回帰分析と比較して、多くの企業で株価変動に対してより高い説明力をもつ特徴量を見出すことができた。 application/pdf

    収集した古文献資料の長期的な維持管理のなかで、資料を電子化することは資料保存の目的や利用者の利便性を高める意義もあり、近年多くの資料保存機関がデジタルアーカイブ事業を展開している。デジタルアーカイブを構築・運営していく上で多くの機関が直面している問題は「如何にして長期的に維持するか」であり、その難しさは現在利用ができない「沖縄の歴史情報研究会」の事例が物語っている。本稿では、デジタル化された資料の長期維持に向けた取り組みとして、「人文学に情報学の技法や技術を応用する」学問である人文情報学(Digital Humanities)の手法を取り入れ琉球大学附属図書館の「琉球・沖縄関係貴重資料デジタルアーカイブ」をIIIF (International Image Interoperability Framework)へ対応した事例や「沖縄の歴史情報研究会」にて作成された「琉球家譜」のデータを再利用する試みを紹介する。現在利用ができない状況である「沖縄の歴史情報研究会」テキストデータのうち、CD-ROM版に収録されていた「琉球家譜」のデータについては現在の環境に適したデータの形へ変換することで再度利活用が可能である。「琉球家譜」のデータファイルを現在の環境で利用可能なデータに変換した上でデファクトスタンダードであるTEI(Text Encoding Initiative)に適用する試行的な取組みを通して、デジタル化された資料の長期的な維持について機関側と研究者が出来る事とは何かを検討し、今後のデジタルコンテンツのあり方について課題を共有したい。 在對收集而來的古文獻資料之長期維持管理的課題上,資料的數位化處理無論在資料保存的目的上或是利用者的便利性而言都有更高一層的意義,於是近年來多數的資料保存機關開始推動數位化資料事業。然而很多機關在數位化資料的架構和運作上所面臨的問題是「如何長期維持」,這個難處就從目前無法利用的「沖繩歷史情報研究會」的實例開始說起。本稿針對數位化資料的長期維持課題,就「人文學上情報學技法和技術的應用」之人文情報學的手法採用,試舉琉球大學附屬圖書館的「琉球沖繩關係貴重資料數位化資料」之IIIF(International Image Interoperability Framework)化處理事例以及重新啟動「沖繩歷史情報研究會」所作「琉球家譜」資料的嘗試。現在無法使用之「沖繩歷史情報研究會」的原檔中,以CD-ROM版收錄的「琉球家譜」資料,可以轉換成適用於現在系統的形式,再度受使用。藉著「琉球家譜」的資料文件的現行系統,採用實際標準的TEI(Text Encoding Initiative)試行轉換,希望能就有關數位化資料的長期維持,一起檢討所屬機關及研究學者所能做的努力,期待今後能將數位化資料內容有關的課題共同分享。

    According to the development of natural language processing technologies, stock price prediction has been made by using various text medium, and the effect is becoming apparent. Focusing on quarterly financial statements, polarity information of text information is often quantified and used to predict stock prices. In this study, we quantified arbitrary semantic information contained in quarterly financial statements by using Sentence-BERT and we found that each component of the embedded vector has statistical significance for stock price fluctuations. 自然言語処理技術の発展に伴い、様々なテキスト媒体を用いた株価予測が行われ、その有効性が明らかになりつつある。決算短信に注目すると、テキスト情報の極性情報が定量化され株価予測に用いられることが多い。本研究では、BERTの改良版であるSentence-BERTを用いて決算短信に含まれる詳細な意味情報を定量化し、得られた埋め込みベクトルの各成分が株価変動に対して徳計的に有意であることが分かった。 application/pdf

    Authors: FUKUNAGA, Masahiro;

    This paper reports on the Jomon pottery materials from the Kasori shell mound located in Chiba City, Chiba Prefecture, among the Gyokusen-kan Collection in the Kyushu University Museum. The Kasori shell mound is composed of two large shell middens (north and south shell middens) of different main periods. The results of the analysis of the pottery indicated that it may have been excavated or collected from the northern shell middens in Kasori shell mound, where the shell middens were formed mainly during the Kasori E type in the latter half of the Middle Jomon period. 九州大学総合研究博物館に所蔵されている玉泉館旧蔵資料のうち,千葉県千葉市に所在する加曽利貝塚から出土した土器資料について報告した.加曽利貝塚は主たる時期の異なる二つの大規模貝層(北貝塚・南貝塚)によって構成されている.当該土器資料を検討した結果,加曽利貝塚の中でも主に縄文時代中期後半の加曽利E式期に貝層が形成された北貝塚で出土あるいは採集されたものである可能性を指摘した. 1.はじめに / 2.加曽利貝塚について / 3.玉泉館旧蔵の加曽利貝塚資料 / 4.当該資料の位置づけ / 5.おわりに

    As products become large-scale and complex, manufacturing industry faces problems in communication between workers. Among the information to be communicated, design rationale, such as reasons for decided design and the process of consideration leading to the decisions, is rarely expressed in shared design data. This paper proposes a information extraction method of design rationale. While design are conducted, conversations are recorded. Recorded sounds are transcribed using the voice input functions in Google Docs. The transcribed data is analyzed by TF/IDF, which evaluates importance of each word in the script by its frequency and rarity. By extracting sentences that contains important words, it is assumed that most design rationales can be depicted. The proposed method was applied to the design of scissors. The case shows that the proposed method has potential for extracting design rationale.

    Authors: Kondō, Kōshi;

    This invited paper provides a detailed essay on the history of gamebooks in Japan from the 1980s to the 1990s. It discusses the impact of the gamebook The Warlock of Firetop Mountain (Jackson & Livingstone, 1982) and how it revolutionized the concept of readers making choices that determine the outcome of the story. The essay also touches on the various genres that gamebooks have covered, the establishment of the term “gamebook” in Japan, and the cultural significance of this interactive form of storytelling. It mentions the rise and fall of the gamebook trend in Japan, including the publication of a dedicated magazine “Warlock” and the shift of focus to tabletop RPGs post the gamebook boom. 80年代から90年代にかけて日本で流行したゲームブックについてのエッセイである.読者が物語の結末を決定する選択をするという概念に革命を起こした『火吹山の魔法使い』(ジャクソン&リビングストン,1982,日本語版 1984)がどのようにジャンルを確立したかを論じる.また,ゲームブックがカバーしてきた様々なジャンル,日本における「ゲームブック」という用語の定着,このインタラクティブな物語形式の文化的意義にも触れている.専門誌「ウォーロック」の創刊や,ゲームブックブーム後のテーブルトークRPGへの移行など、日本におけるゲームブックの盛衰にも考察している. 本文ファイルを差し替え(2024-01-16)

    Due to the development of natural language processing technologies, the effectiveness of text-based investment strategies for stocks has been demonstrated. Focusing on quarterly financial statements, the polarity of the text is often quantified and used for investment strategies. In this study, we quantified the detailed content of quarterly financial statements by using Sentence-BERT to create features and we were able to find features which have higher interpretability on stock price fluctuations from many companies' quarterly financial statements compared to regression analysis. Therefore, we found that decision tree regression can realize the non-linear patterns between the content of quarterly financial statements and stock price fluctuation. 自然言語処理技術の発展に伴い、テキストを用いた株式の投資戦略の有効性が示されつつある。決算短信に注目すると、テキストの極性を定量化し、投資戦略に用いることが多い。本研究では、Sentence-BERTで決算短信の詳細な内容を定量化して特徴量を作成し、株価変動に対して決定木を用いた回帰を行った。その結果、回帰分析と比較して、多くの企業で株価変動に対してより高い説明力をもつ特徴量を見出すことができた。 application/pdf

    収集した古文献資料の長期的な維持管理のなかで、資料を電子化することは資料保存の目的や利用者の利便性を高める意義もあり、近年多くの資料保存機関がデジタルアーカイブ事業を展開している。デジタルアーカイブを構築・運営していく上で多くの機関が直面している問題は「如何にして長期的に維持するか」であり、その難しさは現在利用ができない「沖縄の歴史情報研究会」の事例が物語っている。本稿では、デジタル化された資料の長期維持に向けた取り組みとして、「人文学に情報学の技法や技術を応用する」学問である人文情報学(Digital Humanities)の手法を取り入れ琉球大学附属図書館の「琉球・沖縄関係貴重資料デジタルアーカイブ」をIIIF (International Image Interoperability Framework)へ対応した事例や「沖縄の歴史情報研究会」にて作成された「琉球家譜」のデータを再利用する試みを紹介する。現在利用ができない状況である「沖縄の歴史情報研究会」テキストデータのうち、CD-ROM版に収録されていた「琉球家譜」のデータについては現在の環境に適したデータの形へ変換することで再度利活用が可能である。「琉球家譜」のデータファイルを現在の環境で利用可能なデータに変換した上でデファクトスタンダードであるTEI(Text Encoding Initiative)に適用する試行的な取組みを通して、デジタル化された資料の長期的な維持について機関側と研究者が出来る事とは何かを検討し、今後のデジタルコンテンツのあり方について課題を共有したい。 在對收集而來的古文獻資料之長期維持管理的課題上,資料的數位化處理無論在資料保存的目的上或是利用者的便利性而言都有更高一層的意義,於是近年來多數的資料保存機關開始推動數位化資料事業。然而很多機關在數位化資料的架構和運作上所面臨的問題是「如何長期維持」,這個難處就從目前無法利用的「沖繩歷史情報研究會」的實例開始說起。本稿針對數位化資料的長期維持課題,就「人文學上情報學技法和技術的應用」之人文情報學的手法採用,試舉琉球大學附屬圖書館的「琉球沖繩關係貴重資料數位化資料」之IIIF(International Image Interoperability Framework)化處理事例以及重新啟動「沖繩歷史情報研究會」所作「琉球家譜」資料的嘗試。現在無法使用之「沖繩歷史情報研究會」的原檔中,以CD-ROM版收錄的「琉球家譜」資料,可以轉換成適用於現在系統的形式,再度受使用。藉著「琉球家譜」的資料文件的現行系統,採用實際標準的TEI(Text Encoding Initiative)試行轉換,希望能就有關數位化資料的長期維持,一起檢討所屬機關及研究學者所能做的努力,期待今後能將數位化資料內容有關的課題共同分享。

    According to the development of natural language processing technologies, stock price prediction has been made by using various text medium, and the effect is becoming apparent. Focusing on quarterly financial statements, polarity information of text information is often quantified and used to predict stock prices. In this study, we quantified arbitrary semantic information contained in quarterly financial statements by using Sentence-BERT and we found that each component of the embedded vector has statistical significance for stock price fluctuations. 自然言語処理技術の発展に伴い、様々なテキスト媒体を用いた株価予測が行われ、その有効性が明らかになりつつある。決算短信に注目すると、テキスト情報の極性情報が定量化され株価予測に用いられることが多い。本研究では、BERTの改良版であるSentence-BERTを用いて決算短信に含まれる詳細な意味情報を定量化し、得られた埋め込みベクトルの各成分が株価変動に対して徳計的に有意であることが分かった。 application/pdf
