RUI-Filtering: A content-based, collaborative filtering algorithm using the access log of related items

For content-based filtering, we propose a new filtering method that can reflect the evaluation of another user. Some groups of meta-data are generated among similar contents from many users' access logs, whereas other contents are filtered by group. The method was evaluated to be equivalent to the traditional content-based filtering, and it could recommend contents that were not recommended by the traditional method about 5% of the time. Moreover, when we restricted the number of recommendation contents, our method showed higher performance than the traditional method. Keyword Personalized Service, Collaborative filtering, Content-based filtering, Recommendation System 1. はじめに ネットワークから多くのコンテンツが利用できる 環境が整いつつある今日,多くのコンテンツの中から ユーザが希望とするコンテンツを発見しやすい環境を 提供することが求められている. ユーザの好みに応じてコンテンツを選出する方法 として典型的な 2 つの方法がある. 1 つは Content-based フィルタリング(内容に基づくフィルタリング)と, もう 1 つは協調フィルタリングである. Content-based フィルタリングは,あるユーザに対し, そのユーザが過去に評価を行ったコンテンツの内容を 分析して得られたユーザプロファイルに基づいて推薦 される [1]. つまり,未知のコンテンツであっても,ユ ーザプロファイルとコンテンツの内容が類似していれ ば推薦できる. しかし , 過去の評価が不十分な場合, 満足にコンテンツを推薦できず,評価内容に類似した コンテンツばかりが推薦される傾向がある. 一方,協調フィルタリングは,類似した好みを有す る他のユーザが好んだコンテンツを推薦する [2,3,4]. コンテンツの内容についての評価は行わないため,そ こに付与された情報(メタ情報)は不要である. 更に, 他のユーザの評価を反映した推薦ができ,ユーザの過 去の評価が少ないため Content-based フィルタリング では類似性が判別できず推薦されないコンテンツも推 薦できる. しかし,他のユーザが未評価の新しいコン テンツは推薦できない. そこで,Content-based フィルタリングに協調フィル タリングの効果を得ることができれば,未評価の新し いコンテンツを推薦する際に,協調フィルタリングの 効果をもたらすことができると考える. 例えば,新製 品のダイレクトメールを,新製品の情報と事前に登録 された嗜好情報とが類似するユーザを対象として一斉 に送信する場合,本当は興味があるのに送信対象にな らなかったユーザを発見することが可能となる. 本稿では,Content-based フィルタリングにおいて, 他ユーザの評価の反映をする方式を提案し,その方式 の手順と評価結果について述べる . 2.

Is It Simply a New Language or Is It a Learning Problem

English Language Learners (ELLs) have been over-identified for placement into special education classes for more than 20 years. Causes include a lack of precisely defined constructs for disabilities, funding methods used by states, failure to follow federal legislation, weak prereferral systems to special education in schools, a huge influx of non-English speaking students to the classroom, and a lack of training amongst teachers. Correctly identifying ELLs who also need special education is difficult, but teachers can safeguard against improper identification by taking into account the social, educational, cultural, and language aspects of students' special circumstances, i.e., the needs of the "whole child. " By recognizing that ELLs exhibit similar learning difficulties to students with special needs, experience huge changes in culture and educational styles, and social isolation because of a lack of second language, educators can tailor their assessment techniques and classroom practice to help ELLs function better in the classroom. Schools should consider the emotional, intellectual, physical, and spiritual needs of the student by hiring bi-lingual personnel for assessment for special education, conducting professional development training for classroom teachers, not relying on a single assessment tool, assessing skills in both the native and second languages, and documenting a problem across settings (home and school), among others.

Rationaler på rejse : Fredelig sameksistens eller forandrende dynamikker?

Afdaekningen af de skiftende kulturpolitiske rationaler, der fra midten af det 20. arhundrede til i dag har styret kulturpolitikken og de vekslende kulturpolitiske strategier er Dorte Skot-Hansens forskningsmaessige fortjeneste. Hun har modelgjort dem og dermed skabt et kritisk analytisk vaerktoj med bade nordisk og internationalt gennemslagskraft. Hun har igen og igen understreget, at rationalerne er idealtypiske. Det ene afloser ikke det andet. De lever fredeligt ved siden af hinanden. 'Virkeligheden' bruger og blander dem. Her bliver modellerne - hvad enten de har kulturpolitik i byer, arkitektur, biblioteker eller aestetisk oplevelse og erfaring i centrum - ogsa forforende farlige. Sporgsmalet er nemlig, om det er rigtigt. Som en ramme om sporgsmalet og som udgangspunkt for en diskussion af udviklingen af de kulturpolitiske rationaler og deres indbyrdes dynamik inddrager artiklen teorier, der pa helt andre forskningsfelter giver bud pa, hvad der sker i overgangene fra et samfund, et videnskabeligt samfund, et informationssamfund, et mediesamfund til det naeste. Pa det grundlag udfordrer den tanken om rationalernes fredelige sameksistens.
GPGPU for Evolutionary Algorithms

Les algorithmes evolutionnaires permettent de trouver des reponses satisfaisantes, mais non-necessairement optimales a des problemes complexes. La puissance de ces algorithmes est directement correlee a la puissance de calcul disponible pour leur execution. En effet, ces algorithmes realisent une exploration en parallele de l’espace de recherche, par le biais de l’evolution d’une population d’individus plus ou moins adaptes a la resolution du probleme. La puissance de calcul disponible contraint la taille de la population et donc la capacite d’exploration ou d’exploitation qu’offre un algorithme. Parallelement, nous assistons au developpement des architectures de processeurs multi-cœurs. Ces processeurs peuvent contenir jusqu’a plusieurs centaines de cœurs dans une puce, mais possedent des contraintes structurelles qui imposent une adaptation des algorithmes utilises. Parmi ces processeurs se developpent depuis 2007 les processeurs de type GPGPU (pour General Purpose Graphical Processing Unit), qui sont des versions generalisees de puces de rendu 3D. Ces processeurs possedent jusqu’a plusieurs centaines de cœurs par puce et permettent d’obtenir des accelerations de plusieurs centaines de fois, sur certaines applications. Cette these detaille l’utilisation de telles architectures dans le cadre des algorithmes evolutionnaires. Plusieurs variantes de ces algorithmes sont etudiees, comme la AG / SE et la GP. Des implantations sur architectures mixtes et GPGPUs seules sont etudiees, par l’application a des problemes jouets et reels.
The accuracy influence of different camera calibration conditions to bundle adjsutment of closerange images

ABSTRACT: Nowadays, close range photogrammetry is gradually applied in numerous fields. While using for mapping, the accuracy is a critical problem that we care. Generally speaking, the non-metric camera would be used in close-range photogrammetry. Therefore, the camera should be calibrated carefully before the bundle adjustment is performed on the determination of precise position and orientation of close-range images. However, different camera calibration conditions will affect the accuracy of bundle adjustment. In this study, the Canon EOS 5D, a SLR-type digital camera, will be used and different camera parameters will be calibrated by iWitnessPRO, a closerange photogrammetry software product. The different camera parameters with different camera calibration data sets from different distances will be used to discuss the accuracy influence of bundle adjustment. The bundle adjustment with additional parameters will be used to overcome several imaging systematic errors which are remained from imperfect calibration under operational conditions as part of solution to increase the accuracy of close range photogrammetry. Meanwhile, the results of bundle adjustment with additional parameters will be compared with the results of bundle adjustment. And both of them are performed by using different camera parameters calibrated with different distances. From the test results, the suggestions will be made for the mapping by using close-range images.
Heuristic Weighted Voting

Heuristic Weighted Voting Kristine Perry Department of Computer Science Master of Science Selecting an effective method for combining the votes of classifiers in an ensemble can have a significant impact on the overall classification accuracy an ensemble is able to achieve. With some methods, the ensemble cannot even achieve as high a classification accuracy as the most accurate individual classifying component. To address this issue, we present the strategy of Heuristic Weighted Voting, a technique that uses heuristics to determine the confidence that a classifier has in its predictions on an instance by instance basis. Using these heuristics to weight the votes in an ensemble results in an overall average increase in classification accuracy over when compared to the most accurate classifier in the ensemble. When considering performance over 18 data sets, Heuristic Weighted Voting compares favorably both in terms of average classification accuracy and algorithm-by-algorithm comparisons in accuracy when evaluated against three baseline ensemble creation strategies as well as the methods of stacking and arbitration.
How Students Collaboratively Write using Google Docs

Writing collaboratively is increasing in many professions, including among college students. Students are writing many assignments collaboratively, learning as they go. Writing collaboratively, however, takes coordination and awareness of who has done what. We offer a new tool, DocuViz, which displays the entire revision history of Google Docs, showing more than the one-step-at-a-time kind of snapshot currently available in Docs and Word. Using DocuViz, we analyzed 99 students’ reports from a Project Management class and found it to reveal interesting patterns of collaborative writing. We believe this tool would be useful not just for researchers, but also for the authors themselves and instructors.
Microdata and k-anonymity: a quantitative approach in the Spanish context

This paper offers a quantitative perspective to the debate between privacy and transparency concerning the dissemination of datasets containing potentially sensitive personal information. It applies in the Spanish context methods, some of which had previously been used in the USA, to estimate the number of people who can be identified in anonymized microdata files containing their sex, birth date, and place of residence. The estimations in this paper indicate that 42% of Spanish citizens could be reidentifiable if only these basic demographic characteristics were known.
Performance Analysis and Optimization of the Winnow Secret Key Reconciliation Protocol

Abstract : Currently, private communications in public and government sectors rely on methods of cryptographic key distribution that will likely be rendered obsolete the moment a full-scale quantum computer is realized, or efficient classical methods of factoring are discovered. There are alternative methods for distributing secret key material in a "post-quantum" era. One example of a system capable of securely distributing cryptographic key material, known as Quantum Key Distribution (QKD), is secure against quantum factorization techniques as its security rests on generally accepted laws of quantum physics. QKD protocols typically include a phase called "Error Reconciliation", a clear-text classical-channel discussion between legitimate parties of a QKD protocol by which errors introduced in the quantum channel are corrected and the legitimate parties ensure they share identical key material. This work improves one such reconciliation protocol, called Winnow, by examining block-size choices for Winnow and thus increasing QKD key rate. Block sizes are chosen to maximize the probability that each block contains exactly one error. Further analyses of Winnow are provided to characterize the effects of different error distributions on protocol operation and shed light on the time and communication complexities of the Winnow secret key reconciliation protocol.
Revisiting the benefit of contrastive analysis for early language learning

The new scientific paradigm proposed by cognitive science (cf. Gardner, 1989) gives researchers the chance to revisit the consideration and the role of assumptions, procedures and tools that became outdated with the incorporation of new theories and insights in numerous disciplines. An example for this situation is the treatment that contrastive analysis1 (CA) has been given in different perspectives. Whereas within conductist-oriented theories, CA was expected to prevent learners from making errors and mistakes in the 60 ́s, it was used for giving an explanation of the errors due to interference up to the mid 80 ́s, before being banned from systematic research on second language acquisition (SLA) processes from the late 80 ́s onwards. Notwithstanding, the application of the epistemological underpinnings of cognitivism onto first language and SLA processes allows for a reconsideration of the benefit of CA as a procedural tool for equipping the second language learner with the cognitive support that contributes to the active construction of the knowledge and skills of the future second language.
Towards curricula in design for all for information and communication products, systems and services.

The aim of the Inclusive Design Curriculum Network (IDCnet) is to integrate information and identify core knowledge sets and skills for model curricula in design for all (DfA) specifically for information and communication products, systems and services. Identifying such knowledge and skills is a step towards providing designers with training and competence in inclusive design principles, methods and tools. One of the first major activities of IDCnet is a workshop to be held in Helsinki in February 2003 called ‘Design for All Curriculum: Towards a synergy of the needs of ICT industry and education. ’ The workshop will be bringing together: • Experts from DfA-aware industries to discuss and suggest what they would expect from graduates they would employ who claim to have proficiency in DfA, and • Experts from the academic world, with teaching or research interests in DfA, to use their own experiences in the field to suggest key knowledge sets and skills that would be necessary for curricula in this area. This presentation will: • summarise and discuss the Helsinki results and recommendations • discuss existing fora, information resources, materials and tools which could form part of model DfA curricula • seek further views and opinions from educators, trainers, students, education policy makers and end-users, and • promote the network to a wider audience of those interested in design for all curricula in the specific field of ICT.
Staggered-grid finite-difference acoustic modeling with the Time-Domain Atmospheric Acoustic Propagation Suite (TDAAPS).

This document is intended to serve as a users guide for the time-domain atmospheric acoustic propagation suite (TDAAPS) program developed as part of the Department of Defense High-Performance Modernization Office (HPCMP) Common High-Performance Computing Scalable Software Initiative (CHSSI). TDAAPS performs staggered-grid finite-difference modeling of the acoustic velocity-pressure system with the incorporation of spatially inhomogeneous winds. Wherever practical the control structure of the codes are written in C++ using an object oriented design. Sections of code where a large number of calculations are required are written in C or F77 in order to enable better compiler optimization of these sections. The TDAAPS program conforms to a UNIX style calling interface. Most of the actions of the codes are controlled by adding flags to the invoking command line. This document presents a large number of examples and provides new users with the necessary background to perform acoustic modeling with TDAAPS.
Design of an Efficient Corpus for High-Quality Unit Selection TTS for Bulgarian

In this paper we present the process of designing an efficient speech corpus for the first unit selection speech synthesis system for Bulgarian along with some preliminary results. As the initial corpus is a crucial factor for the quality delivered by the Text-to-Speech system, special effort has been given to design a complete and efficient corpus for use in a unit selection TTS system. The targeted domain of the TTS system and hence of the corpus is the news reports, and although it is a restricted one, it is characterized by an unlimited vocabulary. The paper focuses on issues regarding the design of an optimal corpus for such a framework and the ideas on which our approach was based on. A novel multi-stage approach is presented for efficient corpus design, with special attention given to language and speaker dependent issues, as they affect the entire process. The paper concludes with the presentation of our results and the evaluation experiments, which provide clear evidence of the quality level achieved. 1 The unit selection TTS system for Bulgarian mentioned in this paper is developed at the Institute for Language and Speech Processing (“Athena” Research Centre), in Greece (Raptis, 2009).

Applying Usability Methods to Concept Development of a Future Wireless Communication Device – Case in Maypole

The development of next generation products is difficult because the development team needs to define both the product direction and the product requirements, while there is no clear understanding of who will use the product and what are their requirements. There also is new or not-yet-existing hardware and software technology involved, the product features are constantly evolving and there is no comparable existing product to benchmark against. Usability methods can be used for defining the product direction and product requirements from users’ point of view. Moreover, the user-centred approach can inspire creative and innovative design of the product concept by expanding the developers’ understanding of the users’ world. In this paper we will present a framework for applying usability methods to the concept development of a future communication device. The framework is based on experience gained by the authors in an ESPRIT Long Term Research project called Maypole. Introduction The user-centred design process is often considered to start with a brief, which describes what it is that will be developed. Stanton (1998) presents a simplistic model of a usercentred design process. After receiving the brief and other design constraints, user needs are analysed and information on user requirements, user goals and user tasks is collected. All this is put together to create the system specification. From the specification the process proceeds to prototyping and testing. However, when developing new products the designer do not have a clear starting point.
