【抄録】Automating the process of semantic annotation of digital personal photographs is a crucial step towards efficient and effective management of this increasingly high volume of content. However, this is still a highly challenging task for the research community. This paper proposes a novel solution. Our solution integrates all contextual information available to and from the users, such as their daily emails, schedules, chat archives, web browsing histories, documents, online news, Wikipedia data, and so forth. We then analyze this information and extract important semantic terms, using them as semantic keyword suggestions for their photos. Those keywords are in the form of named entities, such as names of people, organizations, locations, and date/time as well as high frequency terms. Experiments conducted with 10 subjects and a total of 313 photos proved that our proposed approach can significantly help users with the annotation process. We achieved a 33 gain in annotation time as compared to manual annotation. We also obtained very positive results in the accuracy rate of our suggested keywords.

【抄録】In the past, when TV viewers saw important information (such as a map) on TV and wanted to keep that information, they had to write it down. To simplify this, we developed a printing method that uses a data-casting service. This method was accepted by the Association of Radio Industries and Business in early 2004 and was published as STD-B24 Version 4.0. In this method, important information is sent via a data-casting service as a printable (XHTML-print) data file with BML. The service was developed on the basis of STD-B24 Version 4.0 specifications. Because the digital TV does not have a printer driver, printable data has to be sent in a deviceindependent format such as an XHTML-print file. After a TV receives broadcast data, the XHTML- print file is transferred from the TV to a printer, and the user can print high-quality images and data. We have now designed and developed optimized method of BML programming in order to make the best of STD-B24 Version 4.0, and have evaluated the performance and effectiveness of this method.
【抄録日本語訳】従来、テレビ視聴者がテレビで重要な情報(地図など)を見て、その情報を残しておきたい場合、メモをする必要がありました。これを簡略化するために、データキャスティングサービスを利用した印刷方法を開発しました。この方式は2004年初めに電波産業会から受理され、STD-B24 Ver.4.0として発行された。この方式では、重要な情報はデータキャスティングサービスを介してBMLで印刷可能な(XHTML-print)データファイルとして送信されます。このサービスは、STD-B24 Version 4.0の仕様をベースに開発されたものです。デジタルテレビはプリンタドライバを持たないため、印刷可能なデータはXHTML-printファイルのような機器に依存しないフォーマットで送信する必要があります。テレビで放送データを受信した後、XHTML-printファイルをテレビからプリンターに転送することで、ユーザーは高画質な画像やデータを印刷することができます。今回、STD-B24 Ver.4.0を最大限に活用するための最適なBMLプログラミング手法を設計・開発し、その性能と有効性を評価した。

Exploiting users' personal and public information for personal photo annotation(Last author)
【抄録】The advancements of technology have been making digital cameras more and more affordable for everyone. Consequently, digital photographs have grown exponentially this last decade and have been making it beyond the abilities of people to easily manage their own photo collections. Annotation is one of the solutions to solve this burden. Therefore, we propose a semi-automatic annotation engine with contextual metadata generation. Photos with geo-referential information such as Global Positioning System (GPS) are the current tendency, Using the exact location information given by GPS, together with times-tamps, our novel engine semi-automatically generates contextual metadata for each photo from different sources of information namely the public news and users' personal information. We have designed, implemented and tested our system.
