A study on idiosyncratic handwriting with impact on writer identification

© 2018 IEEE. In this paper, we study handwriting idiosyncrasy in terms of its structural eccentricity. In this study, our approach is to find idiosyncratic handwritten text components and model the idiosyncrasy analysis task as a machine learning problem supervised by human cognition. We employ the Inception network for this purpose. The experiments are performed on two publicly available databases and an in-house database of Bengali offline handwritten samples. On these samples, subjective opinion scores of handwriting idiosyncrasy are collected from handwriting experts. We have analyzed the handwriting idiosyncrasy on this corpus which comprises the perceptive ground-truth opinion. We also investigate the effect of idiosyncratic text on writer identification by using the SqueezeNet. The performance of our system is promising

Historical Analyses of Disordered Handwriting

Handwritten texts carry significant information, extending beyond the meaning of their words. Modern neurology, for example, benefits from the interpretation of the graphic features of writing and drawing for the diagnosis and monitoring of diseases and disorders. This article examines how handwriting analysis can be used, and has been used historically, as a methodological tool for the assessment of medical conditions and how this enhances our understanding of historical contexts of writing. We analyze handwritten material, writing tests and letters, from patients in an early 20th-century psychiatric hospital in southern Germany (Irsee/Kaufbeuren). In this institution, early psychiatrists assessed handwriting features, providing us novel insights into the earliest practices of psychiatric handwriting analysis, which can be connected to Berkenkotter’s research on medical admission records. We finally consider the degree to which historical handwriting bears semiotic potential to explain the psychological state and personality of a writer, and how future research in written communication should approach these sources

Computer-Aided Palaeography, Present and Future

The field of digital palaeography has received increasing attention in recent years, partly because palaeographers often seem subjective in their views and do not or cannot articulate their reasoning, thereby creating a field of authorities whose opinions are closed to debate. One response to this is to make palaeographical arguments more quantitative, although this approach is by no means accepted by the wider humanities community, with some arguing that handwriting is inherently unquantifiable. This paper therefore asks how palaeographical method might be made more objective and therefore more widely accepted by non-palaeographers while still answering critics within the field. Previous suggestions for objective methods before computing are considered first, and some of their shortcomings are discussed. Similar discussion in forensic document analysis is then introduced and is found relevant to palaeography, though with some reservations. New techniques of "digital" palaeography are then introduced; these have proven successful in forensic analysis and are becoming increasingly accepted there, but they have not yet found acceptance in the humanities communities. The reasons why are discussed, and some suggestions are made for how the software might be designed differently to achieve greater acceptance. Finally, a prototype framework is introduced which is designed to provide a common basis for experiments in "digital" palaeography, ideally enabling scholars to exchange quantitative data about scribal hands, exchange processes for generating this data, articulate both the results themselves and the processes used to produce them, and therefore to ground their arguments more firmly and perhaps find greater acceptance

Reflex of Avoidance in Spatial Restrictions for Signatures and Handwritten Entries

Regarding the myriad disputed documents encountered within the science of forensic document examination, questioned handwriting is the most prevalent. This includes the simulation or alteration of and or additions to handwriting and signatures. The current study examined the changes that may occur in writing when given a limited amount of space. Several participants completed a survey wherein writing samples were taken under varying space allowances. These space restrictions were made under differing conditions such as boxed signatures, additions to prewritten material, and alterations to letters and numbers. The results of the study found characteristics of reflex of avoidance in the participants\u27 handwriting. These characteristics included changes in height, width, and letter spacing in accordance to the amount of space provided. The examples of reflex of avoidance defined throughout this study may serve to assist forensic document examiners in the detection of alterations within questioned documents

Searching for Dead Sea Scribes:a study on using Artificial Intelligence and palaeography for writer identification in correlation with spelling and scribal practices, codicology, handwriting quality, and literary classification systems for Dead Sea Scrolls

My study explores the Dead Sea Scrolls through the lens of individual scribes. Specifically, the practices of individual scribes responsible for penningtwo or more of the Oumran manuscripts. It utilises innovative digital palaeographic methods alongside traditional palaeographic approaches for scribalidentification. It gathers previously un-gathered data on the handwriting, spelling practices, codicological features and literary content of individual scribes. The study explores how this data on scribes both supports and challenges various aspects of theories in the field of Dead Sea Scroll studies, which accept a a sectarian origin for the Qumran manuscripts

Forensic Linguistics: Science or Fiction?

The history of linguistics is meager and splintered due to the subject’s interdisciplinary nature. In the postwar era, the discipline attempted to revive as a scientific one, spearheaded by Noam Chomsky and his theory of generative grammar. Linguistics consequently broke away from the predominant structuralist approach of the nineteenth century, returning to rationalist roots. But with the rise of computer technology, Chomsky’s critiques of empirical, applicational linguistic approaches have lost their force. As academic linguistics splinters off again, loses its scientific edge, and regroups with the humanities, linguistics applied in the forensic context may implicate more questions than it answers, fundamental questions about humans and language that linguists are still unable to solve: What is language? Do we use language in a way that is uniquely identifiable? Should we look at language use from a societal or individualized, psychological perspective? This Note seeks to reveal these tensions, by providing an overview of the historical development of forensic linguistics; highlights the theory of idiolect backing the use of forensic linguistic evidence; and critiques idiolect and forensic linguistics’ statistical turn in light of linguistics’ ebbing scientific status. As the larger epistemological questions behind forensic linguistic theory remain indeterminate, authorship identification may remain a question of weight, similarity, and difference for judges and juries to grapple with, highlighting the “sliding scale” problem of reliability in the forensic sciences

An examination of the characteristics of disguised and traced handwriting

There has recently been a lack of judicial confidence in the evidence provided by handwriting analysis which has highlighted the need for objective research to be conducted in this area. In response this study has examined the principles and practices of two of the field’s most complex areas of analysis: disguised and artificially assisted (traced) handwriting. Any claims and observations made in the literature have been reviewed and empirically tested. A body of controlled data was collected from sixty volunteers who produced samples of disguised handwriting and traced signatures. A rigorous examination of these samples has been described and quantitative evidence found to support the conclusion that the act of disguising or tracing handwriting will have a negative influence upon the appearance and structure of that writing. Results have shown that disguised and traced writings are intimately related in that they share common characteristics that are indicative of the artificial manner by which they have been produced. Other features are also identified that can be directly associated with specific types of deviant writing to allow for distinctions to be made between them. The analysis is expressed in the form of a comprehensive taxonomy of the distinctive features of deviant writing

The development of writing in four to seven year-old children: a longitudinal study

This longitudinal study investigates the factors at home and school that influence children's attainment and progress in writing at Key Stage 1. Sixty children between the ages of four and seven years in four Reading primaiy schools were tracked and data was collected in the term before they started school, at school entry, on a termly basis once in school and at the end of Key Stage 1. Semi-structured interviews, questionnaires, observation schedules, checklists and standardised assessments were used. Associations between measures and continuity over time were assessed using multiple regression analysis. Pre-school independent variables that were found to be significantly associated with writing proficiency at school entry included mother's educational level, family size, parental assessment of writing and a measure of home writing. Child characteristics, skills and competencies were measured at school entry and those found to be significantly associated with writing at outcome included season of birth, WPPSI-R vocabulary score, pre-reading skills and proficiency in writing their own name. The only pre-school variable that maintained its significant relationship to writing at outcome was home writing. Teacher assessments of pupil attitudes to writing were consistently found to be significantly associated with writing at outcome. Data from the termly writing samples indicated that only the handwriting assessment predicted general writing ability at seven years of age. Eight pupils were observed writing at two points in time and the records are discussed in terms of processes and products. Issues such as quality and quantity of writing generated are considered in relation to the development of component skills (e.g. handwriting, spelling, vocabulary), within the context of the curriculum and role of the teacher. The results confirm the complexity of learning to write for children at Key Stage I and developmental considerations are discussed in relation to policy and practice issues

Raising students' awareness of cross-cultural contrastive rhetoric in English writing via an e-learning course

This study investigated the potential impact of e-learning on raising overseas students' cultural awareness and explored the possibility of creating an interactive learning environment for them to improve their English academic writing. The study was based on a comparison of Chinese and English rhetoric in academic writing, including a comparison of Chinese students' writings in Chinese with native English speakers' writings in English and Chinese students' writings in English with the help of an e-course and Chinese students' writings in English without the help of an e-course. Five features of contrastive rhetoric were used as criteria for the comparison. The experimental results show that the group using the e-course was successful in learning about defined aspects of English rhetoric in academic writing, reaching a level of performance that equalled that of native English speakers. Data analysis also revealed that e-learning resources helped students to compare rhetorical styles across cultures and that the interactive learning environment was effective in improving overseas students' English academic writing
