Document Analysis

The recognition of symbols in graphic documents is an intensive research activity in the community of pattern recognition and document analysis. A key issue in the interpretation of maps, engineering drawings, diagrams, etc. is the recognition of domain dependent symbols according to a symbol database. In this work we first review the most outstanding symbol recognition methods from two different points of view: application domains and pattern recognition methods. In the second part of the paper, open and unaddressed problems involved in symbol recognition are described, analyzing their current state of art and discussing future research challenges. Thus, issues such as symbol representation, matching, segmentation, learning, scalability of recognition methods and performance evaluation are addressed in this work. Finally, we discuss the perspectives of symbol recognition concerning to new paradigms such as user interfaces in handheld computers or document database and WWW indexing by graphical content.

One of the major challenges in camera document analysis is to deal with the page curl and perspective distortions. In spite of the prevalence of dewarping techniques, no standard for their performance evaluation method exists with most of the evaluation done to concentrate in visual pleasing impressions. This paper presents an objective evaluation methodology for document image dewarping techniques. First,

An extensive literature survey on automated assessment and handwriting recognition has shown that no work has been done in addressing the area of assessment of handwritten exam scripts. This paper therefore introduces the novel concept of applying Image Extraction ...

This paper shares the finding of a comparative analysis of the ESL/ELD curriculum Grades 9 -12 (OME, 2007a) (ESL/ELD) and the FSL curriculum Grades 9 -12 (OME, 2014) (FSL) focused on the Ontario Ministry of Education’s (OME) global citizenship goal for second language (L2) learners. Global citizenship has become a curricular goal in many educational systems around the world, including in Canada – Ontario. Learning for global citizenship in tandem with L2 has become advantageous in the 21st century because learning a new language, in addition to promoting career growth, also fosters understanding and acceptance of otherness in the global society. Therefore, it is important to understand how the OME integrates global citizenship principles in the education of English and French L2 learners. Results suggest the ESL/ELD curriculum does not promote global citizenship but aims to prepare students for the job market; however, in competitive disadvantage compared with their English speaker peers.  Additionally, the FSL curriculum’s goal to prepare students for global citizenship, through intercultural understanding, is superficial and inefficient. Findings have shown the OME needs to review the ESL/ELD and FSL curricula to promote global citizenship education and prepare learners to become caring and connected citizens of the world.

Deep ocean water (DOW) is commonly referred to as the water below photic zone in the ocean that is typically cold, clean, stable, and rich in nutrients. Japan and the United States have been exploiting the DOW for utilization in water, pharmaceutical, cosmetic, and fishery industries for many years. Since 2000, Taiwan has started the preliminary planning for the exploitation

As part of an evaluation of an ongoing initiative to train faculty to teach online, semistructured interviews were conducted to identify areas of need and faculty satisfaction. The data indicated that the majority of faculty placed a high value on technical and pedagogical support. However, another very surprising finding emerged from the data; a small number of faculty viewed technological tools as a replacement for pedagogy. To unearth why these individuals held this belief, interview data, ethnographic reporting and document analysis were triangulated in a case study. The results indicated that this phenomenon was likely related to teaching and learning orientations, as manifested in course goals, objectives and activities. This paper presents the study’s findings and concludes with a discussion of the impact on best practice in online learning environments and directions for further research.

À partir d’une enquête ethnographique au Musée national d’art moderne, cet article explore les enjeux de la documentation des collections : chaque œuvre possède en effet son dossier, où sont consignées toutes les informations qui concernent sa carrière au sein du musée. J’examine plus particulièrement le traitement de sa partie dite confidentielle, qui cristallise un certain nombre d’enjeux relatifs à la circulation du savoir sur les œuvres. En croisant analyse de contenu et observation des contextes d’usage des dossiers, j’étudie trois exemples de données confidentielles pour rendre compte de leur signification située. Mon étude montre comment le dossier offre une mise en perspective originale des œuvres, en manifestant leur attachement à l’institution et aux personnes qui s’en occupent.

This article explores the practices undertaken by early childhood development practitioners (ECDPs) to support poor and vulnerable children from birth to four years outside centre‐based provision. The article draws on part of a UNICEF (United Nations International Children's Fund) commissioned evaluation on family and community‐based ECD (Early Childhood Development) programme in the Free State Province of South Africa. The respondents in the study were ECDPs, managers and participants in community projects. The data were produced through interviews, focus group interviews, site visits and document analysis. The findings suggest that ECDPs play an enabling and facilitating role through multiple practices to reach young children and their families both in their immediate and broader environments. Challenges emerge from a lack of recognition of ECDPs as public service workers and contextual factors in poor and vulnerable circumstances. The article concludes with policy implications.

This paper presents a method for vectorizing the graphical parts of paper-based line drawings. The method consists of separating the input binary image into layers of homogeneous thickness, skeletonizing each layer, segmenting the skeleton by a method based on random sampling, and simplifying the result. The segmentation method is robust with a best bound of 50 percent noise reached for indefinitely long primitives. Accurate estimation of the recognized vector's parameters is enabled by explicitly computing their feasibility domains. Theoretical performance analysis and expression of the complexity of the segmentation method are derived. Experimental results and comparisons with other vectorization systems are also provided.

Spätestens seit dem Wirbel um GPT-3 sind Textgeneratoren, Chatbots und andere intelligente Sprachsysteme aus gegenwärtigen Technologiedebatten nicht mehr wegzudenken. Dank des enormen Fortschritts auf diesem Gebiet werden wir zukünftig immer häufiger auf haptische Eingabegeräte verzichten können, Texte von Computern schreiben lassen und Unterhaltungen mit künstlichen Avataren führen. Zusammen mit Wissenschaftlern des Fraunhofer IAIS haben Mitarbeitende der Kompetenzplattform KI.NRW nun eine Studie veröffentlicht, die aufzeigt, an welchen Stellen moderne Sprachtechnologien uns schon jetzt im Alltag begegnen, wie diese eigentlich funktionieren und welche wirtschaftlichen Chancen und Potenziale damit verbunden sind.

There is still a continuing discussion about the effects of the violent cartoons to the young audiences. Many published and unpublished journals and articles were already made by the professional researchers and scholars about this issue. But the media still claimed that there is no enough evidence to for these accusations and assumptions. So, the researcher intended to conduct a document analysis about this issue based on the previous articles, journals and studies regarding media violence. This paper aims to look for research evidences and facts about television programs that contain violence. And also to discuss and explain the effects of watching violent cartoons to the children and it’s relation to Social Cognitive Theory and Cultivation Theory.

The Hough transform provides a robust technique for skew detection in document images, but suffers from high time complexity which becomes prohibitive for detecting skew in large documents. Analysis of time complexity on various stages of skew detection process is carried out in this paper. A complete skew detection and correction process is divided into three parts: a preprocessing stage using a simplified form of block adjacency graph (BAG), voting process using the Hough transform and de-skewing the image using rotation. Skew correction phase, which is hitherto a neglected area, is analysed for the quality of de-skewed images with respect to the type of rotation. Fast algorithms for all the three stages are presented and exhaustive analysis on time complexity is conducted. It is shown that the overall time taken for the whole process is less than one second even for very large documents. It is also observed that time taken in rotation is as significant as in skew detection which is reduced with the help of fast algorithms using integer operations. While the BAG algorithm is found to be effective for documents with Roman script, it does not provide satisfactory results for Indian scripts where headline is a part of a script.

"Die vorliegende Publikation nimmt die Perspektive der betroffenen Kinder im Kinderschutz ein und geht der der Frage nach, inwieweit deren Bedürfnisse und Wünsche bei der Gestaltung des Hilfeprozesses Berücksichtigung finden und einfließen. Die Autorinnen und Autoren der Studie plädieren für eine stärkere Partizipation von Kindern und Jugendlichen im Kinderschutz.

Vor diesem Hintergrund wurde die vorliegende explorative Studie auf der Basis einer ausschnitthaften empirischen Analyse von zehn Kinderschutzakten aus fünf Kommunen erstellt. Sie betrachtet die unterschiedlichen Perspektiven der Fachkräfte und der betroffenen Kinder und Jugendlichen, stellt die Befunde aus der Aktenanalyse vor und gibt erste Hinweise für eine bessere Einbeziehung der Kinder und Jugendlichen. Darüber hinaus werden Ansätze für weitere Forschungen in diesem Bereich diskutiert."
