DEIM フォーラム 2020 開催報告合田和生 (東京大学) 第12回データ工学と情報マネジメントに関するフォーラム第18回日本データベース学会年次大会（DEIM2020） https://bit.ly/2mayS6p 主催：電子情報通信学会データ工学研究専門委員会日本データベース学会情報処理学会データベースシステム研究会日程：2020年3月2日（月）〜3月4日（水）会場：DEIM2020オンラインポータルに於けるオンライン開催（磐梯熱海ホテル華の湯に代えて）〇開催概要データ工学と情報マネジメントに関するフォーラム／日本データベース学会年次大会（DEIM）は、データ工学と情報マネジメントに関する様々な研究テーマの討論・意見交換を目的とした研究集会であり、当該分野では国内最大規模を誇ります。毎年、合宿形式で開催しており、深い議論や活発な研究交流を促進している点が特長的で、大学・企業の若手教員・研究者・技術者および学生からの発表の他に、一般からの発表も広く受け付けるとともに、近年は産学連携に向けた活動を強化しています。この度のDEIM2020については、当初は3月2日（月）から4日（水）にかけて福島県の磐梯熱海ホテル華の湯を会場として、例年と同様の規模で開催するべく、準備を進め、論文投稿を募集するとともに参加申込の募集を行っておりましたが、新型コロナウイルス感染症が我が国においても拡大する傾向が見られたことから、2月17日（月）に会場に於ける開催を中止することとし、これに代えて、ほぼ同じスケジュールでオンライン会議システムを用いたオンライン開催を執り行うこととしました。この結果、オンライン開催ではあるものの563名の参加者にお集まりいただき、予定していた316件の口頭発表と55件のインタラクティブ発表の全てとそれらの質疑を終えることができました。加えてDBSJアワーを開催し、日本データベース学会業績賞ならびに功労賞の授賞式を挙行しました。功労賞を受賞された宮崎収兄先生（千葉工業大学名誉教授）および三浦孝夫先生（法政大学教授）からは永年のデータベース分野のご研究に関する講演をいただきました。また、DEIMの培ってきた合宿形式の雰囲気を少しでも感じ取れるようにしようとBanquet Onlineなる新たなネットワーキングの試みを実施しました。〇オンライン開催への挑戦新型コロナウイルス感染症の拡大に伴い、今日では多くの学術集会がオンライン開催を試みるようになってきていますが、振り返りますとDEIM2020のオンラインでの開催を決断した2月17日（月）の時点では、オンライン会議システムによって十分な研究発表と質疑を行うことができるかどうかは、必ずしも見極めることができていた訳ではありませんでした。情報学分野の学術団体が率先して挑戦することが重要だと考え、「壮大な実験」と称して、参加者の皆様に対して開催方法の変更へのご理解とオンライン開催へのご協力をお願いしました。最終的には上述の通り、例年と同規模での開催を行うことができました。オンライン開催の準備を進める過程では、参加者の皆様に3回に渡る実証実験への参加を呼び掛け、延べ380名の参加者にご参加をいただきました。実験によって得られた知見をもとに編纂されたオンライン会議の進行マニュアルは、情報処理学会全国大会等の開催等へ活用されています。DEIM2020の開催は、コミュニティの広く温かいご理解とご支援によって実現されたものです。全ての参加者の皆様のご協力に感謝を申し上げます。なお、壮大な実験と宣言したものの、実行委員会にはオンライン会議システムの構築や運用を行うための技術的な用意が十分ではなく、謂わば「意気込みだけ」の状態でした。国立情報学研究所（NII）に相談したところ、わずか半日足らずのうちに技術支援チーム（通称「DEIM成功させ隊」）が編成され、DEIM2020の終了に至るまで昼夜を問わずご支援を頂戴しました。実行委員会の細かいお願いの一つ一つを機動的かつ丁寧に叶えていただきました。NIIからいただいた献身的なご支援に深く感謝を申し上げます。〇産学連携の強化前回のDEIM2019では、産学連携に向けた活動を強化する方針を新たに定め、協賛企業を募り、常駐ブースの設置や協賛企業による技術報告講演やライトニングトークを行いました。DEIM2020では産学連携委員会を立ち上げて当該方針を強化することとし、その趣旨に賛同いただいたアマゾンウェブサービスジャパン（株）、（株）サイバーエージェント、（株）Gunosy、（株）LIFULL、LINE （株）、（株）野村総合研究所、楽天（株）、（株）リクルートテクノロジーズ、Sansan （株）、ウォンテッドリー（株）、ヤフー（株）、（株）ZOZOテクノロジーズの12社（アルファベット順）の企業から協賛の申し出をいただきました。上述の通り新型コロナウイルス感染症の拡大によって、DEIM2020は会議場での開催からオンラインでの開催へ開催方法を変更したものの、これらの全ての企業から継続的に協賛する旨の力強いメッセージを頂戴しました。協賛企業12社のお力添えに深く感謝申し上げます。〇論文投稿システムの刷新オンライン開催の陰で、こっそりと幾つかの変更も行いました。大きなものに論文投稿システムの刷新が挙げられます。恐らく10年ほど前に導入された論文投稿システムを使用して来たのですが、今ではDEIMの実務から大きく乖離し、著者と運営の両サイドにとって使いにくいものになっていました。これをプログラム委員会が中心となって、一から開発し直しました。今やDEIMのプログラム編成にとっては欠くことのできないクラウドソーシングシステムとも円滑に連携できるようになっています。奇しくもDEIM2020はオンライン開催することとなりましたが、オンラインポスタ閲覧機能、オンライン会議ポータル、オンライン参加証明書といったDEIMならではのきめ細やかなサービスの提供を可能とする等、自前の論文投稿システムが大きな縁の下の力持ちとなりました。〇ローカルアレンジメント業務の見直し残念ながら開催のオンライン化によって今回は日の目を見ることはなくなってしまいましたが、アレンジメント業務についてもローカル委員会を中心に見直しを進めました。DEIMはその前身のDEWSの時代から一貫して成長してきていますが、この過程で様々な附随業務が肥大化し、運営負担が増大してきています。同時に従来の枠組みにとらわれることなく、新しい試みに挑戦することのできる胆力も必要です。受付や採点の手続きを概ねペーパレス化することによって業務の軽減を行うとともに、チャイルドケアサービスをより利用しやすくするといった見直しを行いました。これらは次回のDEIMで存分に活躍してくれるでしょう。〇おわりに DEIM2020にご参加いただいたコミュニティの皆様、オンライン開催に献身的なご支援をいただいたNIIの皆様、開催方法の変更にも関わらず温かくご支援を継続していただいた協賛企業12社の皆様、当初の会議場・宿泊施設の準備を丁寧にお進めいただいた関係団体の皆様に、心より御礼申し上げます。オンライン開催に接し、多くの参加者の方は意外とオンラインであっても学術集会は開催できるのだと理解しつつも、どこか一抹の物足りなさもお感じになったのではないかと思います。本稿の執筆時点では、新型コロナウイルス感染症が世界的に蔓延し、社会全体は不安に包まれています。疫病禍が早期におさまり、来年のDEIM2021では会場で皆様と会えるようになることを願っています。

データ解析コンペティションは、「共通の実データを元に、参加者が分析を競う」ことを目的として、平成6年度から毎年開催されています。平成25年度からは ACM-SIGMOD日本支部と日本データベース学会ビジネスインテリジェンス研究グループの共同体制で、データベース分野独自の予選会（DB部会）を開設しています。今年度のDB部会の委員構成は、次の通りです。主査：大塚真吾（神奈川工科大学）、関根純（専修大学）委員：井上潮（東京電機大学）、宇田川佳久（東京工芸大学）、鬼塚真（大阪大大学）、北山大輔（工学院大学）、波多野賢治（同志社大学）、増田英孝（東京電機大学）（五十音順）令和元年度は8月5日から翌年3月31日までの期間で、みずほ情報総研株式会社様にご協力いただき、都内タクシー1万台弱のプローブデータ（提供期間は2016年 4月〜2018年3月の2年間）の提供を受け、約100チーム、延べ約600名が参加しました。 DB部会の参加は7チームで、12月中旬にウェブ上で中間報告会を行い、2月24日に最終報告会を開催する予定でしたが、COVID-19の感染拡大の影響を受け、急遽、報告会は中止とし、最終報告書と発表用スライドをもとに、審査をすることとなりました。DB部会主査・委員による厳正な審査の結果、最優秀賞は「標準地域メッシュを用いたタクシー移動方位の変動評価」を発表したブラックキッズ +（大東文化大学）、優秀賞は「再帰型ニューラルネットを用いたタクシー乗降車数の予測」を発表したチーム九段下（東京理科大学）が受賞しました。最優秀賞ブラックキッズ+は、コンペティション全体の成果報告会（各部会の代表チームが出場）において発表を行う予定です。（当初は3月19日の開催予定でしたが、COVID-19の感染拡大の影響により、6月20日(土)開催を軸に調整中です。）今回は各チームの解析技術の向上に加えて、特に上位2チームは綿密な解析によりタクシーの需要や乗降車数について高精度の予測を行っており、ビジネスに有用な知見を示したことが高評価に結び付いたと感じました。一方で、DB部会への参加チームが少なく、コンペティション全体における存在感がまだ十分ではありません。このコンペティションは、オープンなデータではなく、企業が実際の業務で使用している生に近いデータを利用できることが大きな特徴になっています。令和2年度も8月頃から新たなデータの提供を受けてスタートする予定ですので、実践的なデータ解析に興味をお持ちの方々は、参加をご検討ください。参考URLは、以下の通りです。経営科学系研究部会連合協議会：

International Conference on Big Data and Smart Computing was held at BEXCO, Busan, Korea from 19th to 22nd February 2020. BigComp is a relatively new conference, with a history of not more than seven years, however I believe that it is emerging as a reputable and a prestigious platform for the researchers working in the different areas of databases and data mining including big data, stream processing, smart computing, graph processing and artificial intelligence. Although due to the New Coronavirus (COVID-19), a few authors could not attend the conference, yet at-least 200 participants including authors and non-authors from around the world attended the conference and presented their work. The BigComp 2020 conference comprised of several workshops, keynotes, tutorials and technical sessions during the span of four days. According to the organizers, overall, 173 submissions were received from around the world, out of which 36 papers were accepted as full while 31 were accepted as short. This brings the acceptance rate of 20.8 for the full papers. In total, 315 faculty members, researchers and students registered for the conference, however approximately only 200 could physically attend the conference due the novel coronavirus. The authors of the countries with the major virus outbreak were given the option to present their work remotely via skype or pre-recorded video. In total, 6 papers were given the best paper awards, with 1 at the first place, 2 at the second place and 3 at the third place. The best paper award winners were presented with a certificate and a small gift. Following is the list of the best papers. o Best Paper Award – 1st Place 1. Deep Learning based Response Generation using Emotion Feature Extraction, Young-Jun Lee (KAIST, Korea) and Ho-Jin Choi (KAIST, Korea) o Best Paper Award – 2nd Place 1. Spatiotemporal Deep Learning Model for Citywide Air Pollution Interpolation and Prediction, Van-Duc Le (Seoul National University, Korea), Tien-Cuong Bui (Seoul National University, Korea), and Sang-Kyun Cha (Seoul National University, Korea) 2. GraphWGAN: Graph Representation Learning with Wasserstein Generative Adversarial Networks, Rong Yan (Taiyuan University of Technology, China), Huawei Shen (Chinese Academy of Sciences, China), Qi Cao (Chinese Academy of Sciences, China), Keting Cen (Chinese Academy of Sciences, China), and Li Wang (Taiyuan University of Technology, China) o Best Paper Award – 3rd Place 1. Optimal Margin Distribution Machine with Sparsity Inducing Penalty, Teng Zhang (Huazhong University of Science and Technology, China) and Hai Jin (Huazhong University of Science and Technology, China) 2. Transaction-aware Data Cluster Allocation Scheme for Qcow2-based Virtual Disks, Minho Lee (Sungkyunkwan University, Korea) and Young Ik Eom (Sungkyunkwan University, Korea) 3. Trainable Multi-Contrast Windowing for Liver CT Segmentation, Jangho Kwon (Korea Institute of Science and Technology, Koera) and Kihwan Choi (Korea Institute of Science and Technology, Korea) The Day 1 was reserved for the several international workshop. Overall, 11 workshops were scheduled on day 1 (19th February), however due the COVID-19, one workshop was canceled. Out of the remaining 10 workshops, 2 were full day workshops and 8 were half day. Following is the list of the 11 workshops co-located with BigComp 2020. 1. The First International Workshop on Conceptual Modeling for Big Data and Smart Computing (CMComp2020) 2. The Third International Workshop on Computing and Information Technology for Self-Driving and Autonomous Mobility (DrivComp2020) 3. The First Workshop on Blockchain and Smart City Service Platform (Korean Only) 4. The Second International Workshop on Big Data, Cloud, and IoT Technologies for Smart Cities 5. Industrial Security - eGovernance Vision and Strategy 6. Computational Data Science for Healthcare and AI (*Cancelled) 7. The Third International Workshop on Big Data Analysis for Smart Energy (BigData4SmartEnergy 2020) 8. The Third International Workshop on Dialog Systems (IWDS) 9. The First International Workshop on Social Health in the Era of Big Data (SHEBD 2020) 10. The First Workshop on Multimodal, Expeditive, Generative and Actionable AI (MEGA AI 2020) 12. The First International Workshop on Research Data Analysis and Utilization (RDAU 2020) The main conference was held from 20th to 22nd February 2020. The main conference was comprised of a mix of technical sessions, keynotes and tutorials. The first keynote on Day 2 was presented by Prof. Masaru Kitsuregawa of University of Tokyo on the topic “the Data Challenges Towards the Realization of Society 5 Vision”, which was quite thoughtful. The talk was delivered as a recorded video due to the novel coronavirus, hence there was no opportunity to ask questions. The keynote was later followed by several technical sessions. The Day 3 started with a panel discussion of experts followed by a keynote speech by Prof. Jiawei Han of University of Illinois at Urbana on the topic “Mining Unstructured Big Text: A Multi-Dimensional Analysis Approach”. Again, the talk was delivered as a recorded video due to the novel coronavirus, hence there was no opportunity to ask questions, however the talk was informative and useful. The talk was followed by several technical sessions. The Day 4, the last day, experienced very low attendance at the conference due the extreme coronavirus warnings from the Korean government. The keynote talk on the topic “Hybrid Deep Learning with Explainable Latent Space for Big Data Analysis” was delivered by Prof. Dr. Sung-Bae Cho of Yonsei University. This was the only keynote during BigComp 2020 which was delivered live. Beside the keynotes and the technical sessions, the following four very informative tutorials were also part of BigComp 2020. 1. Blockchain and its Security Risk by Kazumasa Omote, Mitsuyoshi Imamura and Teppei Sato (University of Tsukuba) 2. Explainable Artificial Intelligence (XAI) by Jaesik Choi (KAIST) 3. Detecting Communities and Anomalies in Large Real-world Graphs by Sungsu Lim (Chungnam National University) and Kijung Shin (KAIST) 4. Big Data - AI Integration by Steven Euijong Whang (KAIST) (Salman Ahmed Shaikh, Data Platform Research Team, AIRC, AIST) -------------------------------------------------------------------- ■４■ AAAI 2020 参加報告数原良彦 (Megagon Labs) 2/9から2/12までニューヨーク市で開催されたAAAI 2020に参加してきました。 4000名以上が事前登録をしていたとのことですが、新型コロナウイルスによる中国本土からの渡航禁止により、参加できなくなった800名以上が不参加ということでした。感覚的には不参加人数はもっと多かったように思います。奇しくも3 年前に参加したIJCAI 2016と全く同じ会場で、懐かしい気分になりました。そのときの参加者は1000人は超えていたと記憶していますが、2000人にはほど遠く、それでも会場は混雑して人に酔った記憶があり、その感覚からするとAAAIは公表された以上に不参加人数が多かったのかもしれません。 ●採択件数と傾向今回の採択率は20.6%で、昨年 (16.2%) から一昨年 (24.6%) に回帰した感じになっています。フルペーパーの投稿件数が7,737とものすごい勢いで増えているので、採択絶対件数は昨年の1150件から1591件と大幅に増えています。国別採択件数では日本は8位（35件採択）でした。私が参加してきた国際会議の中でも日本人が比較的多い会議だな、と思いました。 AAAIは広範囲に渡る論文が発表される印象でしたが、トピックとしては ML >> Vision ≒ NLPの３つのトピックが大部分を占めていて、知識表現、探索、アルゴリズムと言ったいわゆる人工知能の中心的なトピックが隠れてしまっている印象でした。 ●チューリング賞受賞者の講演今回のAAAIの目玉はなんといっても、チューリング賞受賞のYoshua Bengio、 Yann LeCun、Geoffrey Hintonの三人の講義でしょう。Geoffrey Hinton がひたすらカプセルネットワークを推す一方で、Yann LeCun はうまくまとめつつ、 Yoshua Bengio が Daniel Kahneman の System 1/System 2 の理論をベースにビジョンを語るという三者三様のトークで会場は大盛りあがりでした。三人の講演に共通することとして、Transformer のような self-attention ベースのモデルとself-supervised learning の重要性が強調されていた点があげられます。これはある意味で納得なのですが、すでに流行になっているものに対して火に油を注いで過剰な流行を招くことにならないか、という部分が少し心配になりました。 ●セッションの様子各セッションは、オーラル2-3件のあとに10件程度のポスターのスポットライト発表があったのですが、多くのセッションですべてのオーラルがビデオ発表、スポットライトもNo Showが散見され、かなりの異常事態でした。同様にポスターセッションもいくつかのNo Showがあったり、ポスター発表者に質問したら、著者ではない代理の方だったり、と、大変な状況でした。私は今取り組んでいるNLPを中心に聴講しましたが、ニューラルネットワークベースの手法が中心であることは当然のこと、Transformerベースの手法、 pre-trained 言語モデルを使うアプローチが主流になっていました。RNNを使っていると「なんでTransformer使わないの？」という感じの反応をされます。これらの背景が共有されている前提で発表、議論が行われるので、とテクニカルな議論という意味ではポイントに集中して議論できるのでよかったのですが、少しでも分野を外れると議論についていけないですし、本質的にどのような問題を解けたのか、という議論が少ない印象でした。流行といえば、今回の自分たちの発表とかなり似たアイディアがAAAIで発表されており、ポスターを聴講に来た著者のひとりに「明後日に似たアイディアを発表するよ」と教えてもらったりしました。また、昨年11月のEMNLPで発表されたものとかなり類似するアイディアがAAAIで発表されていたりと、本分野の発展の速さにぞっとしました。 ●自発表とAAAI投稿について私は共著で "Emu: Enhancing Multilingual Sentence Embeddings with Semantic Specialization" という論文を発表してきました。異なる言語の文を同じ埋め込み空間に射影して、文類似度を直接計算することが可能な多言語文埋め込みモデルは、表層表現の類似度に敏感で、意味的な類似度を測るのが苦手であるという問題があります。これに対し、単一言語のラベル付きデータを使ってモデルを改善するというアイディアです。これは昨年のインターン生の成果でして、会社で解説記事も書いたのでよろしければそちらをご覧ください。 Emu: Enhancing Multilingual Sentence Embeddings with Semantic Specialization Wataru Hirota, Yoshihiko Suhara, Behzad Golshan, Wang-Chiew Tan https://megagon.ai/blog/emu-enhancing-multilingual-sentence-embeddings-with… 論文投稿に関しては最初のレビューがなかなか厳しく、正直これは厳しい、と内心諦めていたのですが、Author response に全力を尽くして回答したところ、 Reject判定をしていた三人目のレビュワーがWeak Acceptに上がり、採択判定となりました。こんな経験は共著者を含めて初めてだったので、とても驚きました。上述のとおり類似のアイディアが出てきていましたので、今回不採録だった場合には、もう国際会議への採録は難しかったかもしれません。諦めたらそこで試合終了だよ、と某先生もおっしゃっていたように、諦めずに今の試合に全力を尽くすことが大切だと再認識しました。共著者たちと論文を書いたり修正しながら学んできたように、論文とは研究コミュニティ（査読者、読者）とのコミュニケーションなのだな、と査読結果を受け取るたびに実感します。必ずしも思い通りにならないという、コミュニケーションにひとつの正解はないですし、これからも日々コミュカアップに精進したいと思っています。 (数原良彦 Megagon Labs) -------------------------------------------------------------------- ■５■ VLDB 2020への道（その7） Van-Dang Tran (総合研究大学院大学)、佐々木勇和 (大阪大学)、天方大地 (大阪大学) 今回のVLDBへの道では，PVLDB vol.13に採択されたVan-Dang Tranさんのご経験を共有いただきました．採択に至るまでの経緯・工夫についてご覧頂けます． ============ My experience in submitting a paper to VLDB 2020 I have been engaging in database research since I joined the Programing Research Laboratory in National Institute of Informatics (NII), Japan in 2017. My research interest lies at the intersection of programming languages and databases. In particular, I am studying query languages and bidirectional programming in relational databases. I have been working with my supervisors, Prof. Zhenjiang Hu and Prof. Hiroyuki Kato, who provided me invaluable suggestions and advice. It is very great that my research result was recently accepted to publish in the 46th International Conference on Very Large Data Bases (VLDB), a top conference of database research, which is held in Tokyo this year. This good start highly motivated me to pursue my Ph.D. research. Unlike most computer science conferences, VLDB has a journal-style review and quality assurance process. We can submit a paper to VLDB every month and get the notification after one and a half months. We have up to three months to revise the paper for the second round of evaluation if requested after the notification. I submitted my paper to VLDB 2020 on July 1st, 2019. I was very lucky that although three reviewers didn’t all accept my paper in the first round, they gave me a chance to revise the paper. I carefully read all the comments from reviewers to understand reviewers’ concerns and make a good plan for my paper revision. The reviewers gave me some big comments and I realized that I needed to intensively modify the paper, and carry out more serious experiments for my research method. In my opinion, experiments are very crucial in the paper evaluation since VLDB is not a theoretical conference. It took me all three months to complete the intensive revision. I got the accept notification after that one month. Actually, before submitting the paper to VLDB 2020, my paper was rejected from PODS 2019. Although the PODS reviewers did not accept my paper, they encouraged me to improve the writing presentation which was the main issue of the paper. I also got other valuable comments to simplify the theory I presented in the paper, even minor comments about the notation convention I used. Perhaps, being rejected from PODS 2019 was not bad news to me because from that I can learn a lot of things from database experts. That was the basis for me to strengthen the practicality of my research contributions, thereby perform experiments and submit the result to the VLDB conference. The important lesson I learned from the PODS submission as well as from revising my VLDB paper is that we should avoid writing too many formal things in the paper. Instead, we can give more examples with clear explanations and intuition that are very helpful to convey our idea to the readers. The VLDB reviewers suggested me to fully write the uninteresting proofs in another report and cite the full report in the main VLDB paper. From my experience, the key factor on my path to paper acceptance I would like to suggest is that we should resolve all reviewer’s concerns and clearly explain how we resolve that in a response letter. For VLDB revision submission, we can write a supplementary “Response to Reviewer Comments” with a maximum of 4-pages length. I fully used the 4 pages in the response letter to summarize all the revisions I made in the paper and answer reviewers’ questions individually. Of course, the main (not every) revised parts in the paper should be highlighted for easily following. Another minor but important thing is that it is very helpful to group and summarize the reviewer’s questions before answering them all. This will recall the reviewers’ concerns because the revision process may take a long time. Any concerns of the reviewers that we can not clarify may lead to paper rejection. It is my pleasure to share my experience of submitting papers at a top database conference. Hopefully, this will be helpful for others to make submissions and contribute to the database research of Japan.

[論文募集] ブロックチェーンのSpecial Issues in Sensors and PPNA
by Yang Cao 20 Mar '20

20 Mar '20

日本データベース学会の皆様京都大学の曹です。お世話になっております。 2つブロックチェーンに関するSpecial IssuesのCFPを送りいたします。 *Sensors*: Special Issue "Emerging Blockchain Technology Solutions for Real-world Applications (EBTSRA)" https://www.mdpi.com/journal/sensors/special_issues/EBTSRA *Peer-to-Peer Networking and Applications (PPNA)*: Special Issue on Blockchain for Peer-to-Peer Computing https://www.springer.com/journal/12083/updates/17751820 論文提出の〆切は2020年10月末です。投稿をご検討をよろしくお願いいたします。曹洋 ---------------------- Call for Papers 1: *Sensors*: Special Issue "Emerging Blockchain Technology Solutions for Real-world Applications (EBTSRA)" https://www.mdpi.com/journal/sensors/special_issues/EBTSRA Deadline for manuscript submissions: 31 October 2020. This Special Issue comprises papers presented at the 2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring) Workshop on Emerging Blockchain Technology Solutions for Real-World Applications (EBTSRA), held 25–28 May 2020 in Antwerp, Belgium. This semi-annual flagship conference of the IEEE Vehicular Technology Society will bring together individuals from academia, government, and industry to discuss and exchange ideas in the fields of wireless, mobile, and vehicular technology. *This Special Issue is also open to other submissions. * A blockchain is a secured, shared, and distributed ledger that facilitates the process of recording and tracking resources without the need of a centralized trusted authority. The technology is scalable and robust, and all participant nodes provide resources fairly, which alleviates many-to-one traffic flow bottlenecks. This technique decreases traffic delays and defeats errors due to a single point of failure. However, blockchain is still a nascent technology and as such there are challenges for the wide adoption of blockchain as a new enterprise and operational layer. These challenges are around scalability, interoperability, standards, privacy, security, governance, and consensus mechanisms, which need to be defined and validated for real-world applications. This workshop opens a forum to present the recent research work related to blockchain-based technologies (e.g. smart contracts, threat and attack models, and incentive mechanisms). Moreover, research on other aspects inherently present in blockchain-based applications, like the internet of things, smart grids, e-health, logistics, etc. are also invited in this workshop. This Special Issue seeks original unpublished papers focusing on theoretical analysis, emerging applications, novel system architecture construction and design, experimental studies, and social impacts of blockchain. Both review/survey papers and technical papers are encouraged. Topic areas include, but are not limited to, the following: Blockchain in 5G technologies; Blockchain in IoT; Blockchain in information-centric networking; Blockchain in smart grids; Blockchain in artificial intelligence; Blockchain in networking and edge/fog/cloud technologies; Blockchain in e-health; Blockchain in decentralized financing and payments; Blockchain in social networking; Blockchain in agriculture; Blockchain in autonomous vehicles; Blockchain in mobile cellular networks; Blockchain standardization; Blockchain tools, simulators and test-bed; Private blockchain systems; Decentralized storage in blockchain; Security, privacy, and trust of blockchain and distributed ledger technologies; Secure smart contracts; Consensus mechanisms. We are proud to announce our agreement with MDPI to publish a Special Issue on Emerging Blockchain Technology Solutions for Real-World Applications (EBTSRA) and cordially invite all researchers to publish a full paper in this Special Issue of the journal Sensors (ISSN1424-8220; *Impact Factor 3.031*; https://www.mdpi.com/journal/sensors) published online by MDPI, Switzerland.

The technology is scalable and robust and all participant nodes provide resources in a fair manner, which alleviates many-to-one traffic flow bottlenecks. This technique decreases traffic delays and defeats errors due to a single point of failure. However, blockchain is still a nascent technology and as such there are challenges for the wide adoption of blockchain as a new enterprise and operational layer. These challenges are around scalability, interoperability, standards, privacy, security, governance and consensus mechanisms that need to be defined and validated for peer-to-peer computing. This special issue opens a forum to present the recent research work related to blockchain-based technologies, e.g. smart contracts, threat and attack models, and incentive mechanisms. Moreover, research on other aspects inherently present in blockchain-based applications, like the Internet of things, smart grid, e-health, logistics, etc. are also invited to this special issue. Topics of Interest This special issue seeks original unpublished papers focusing on theoretical analysis, emerging applications, novel system architecture construction and design, experimental studies, and social impacts of blockchain. Both review/survey papers and technical papers are encouraged. Topic areas include, but are not limited to, the following: Blockchain theories and algorithms for P2P computing Blockchain architectures, protocols and algorithms for P2P computing Blockchain based security, privacy, and trust for P2P computing Network and computing optimization in blockchains for P2P computing Decentralization optimization in blockchain empowered P2P computing Scalable consensus algorithms for P2P computing Lightweight blockchain designs for P2P computing Innovative applications and research in blockchain for P2P computing Blockchain in information-centric networking Blockchain in smart grid Blockchain in artificial intelligence Blockchain in networking and edge/fog/cloud technologies Blockchain in e-health Blockchain in 5G technologies Blockchain in decentralized financing and payments Blockchain in social networking Blockchain in agriculture Blockchain in autonomous vehicles Blockchain in mobile cellular networks Blockchain standardization Blockchain tools, simulators and test-bed Private blockchain systems Decentralized storage in blockchain Security, privacy, and trust of blockchain and distributed ledger technologies Secure smart contracts Consensus mechanisms Paper Submission Authors are encouraged to submit high-quality, original work that has neither appeared in, nor is under consideration by, other journals.

Papers that describe experiments on human subjects, or that analyze nonpublic data derived from human subjects (even anonymized data), should briefly describe how the research protocol addresses ethical considerations and whether their work was vetted by an ethics review (e.g., IRB approval). We expect authors to follow the rules of their host institutions around data collection and experiments with human subjects. Accepted submissions will be available on the ACM digital library at most two weeks before the conference.
