Automatic dictionary and rule-based systems for extracting information from text

The paper offers a general introduction to the use of meta-information in a text mining perspective. The aim is to build a meta-dictionary as an available linguistic resource useful for different applications. The procedure is based on the use of a hybrid system. The suggested algorithm employs, conjointly and in a recursive way, dictionaries and rules, the latter both lexical and textual. An application on a corpus of diaries from the Time Use Survey (TUS) by Istat is illustrate

Evaluating the audio-diary method in qualitative research

Purpose Audio-diary methods are under-utilised in contemporary qualitative research. In this paper we discuss participants and researchers’ experiences of using audio-diaries alongside semi-structured interviews to explore breastfeeding experiences in a short-term longitudinal study with 22 first-time mothers. Design/methodology/approach We provide a qualitative content analysis of the participants’ feedback about their experiences of the audio-diary method and supplement this with the perspectives of the research team based on fieldwork notes, memos and team discussions. We pay particular attention to the ways in which the data attained from diaries compared with those from the interviews. Findings The diaries produced were heterogeneous in terms of data length and quality. Participants’ experiences with the method were varied. Some found the process therapeutic and useful for reflecting upon the development of breastfeeding skills whilst negative aspects related to lack of mobility, self-consciousness and concerns about confidentiality. Researchers were positive about the audio-diary method but raised certain ethical, epistemological and methodological concerns. These include debates around the use of prompts, appropriate support for participants and the potential of the method to influence the behaviour under scrutiny. Interview and diary accounts contrasted and complemented in ways which typically enriched data analysis. Practical implications The authors conclude that audio-diaries are a flexible and useful tool for qualitative research especially within critical realist and phenomenological paradigms Originality/value This appears to be the first paper to evaluate both participants and researchers’ experiences of using audio-diaries in a detailed and systematic fashio

The use of diaries in psychological recovery from intensive care

Intensive care patients frequently experience memory loss, nightmares, and delusional memories and some may develop symptoms of anxiety, depression, and post-traumatic stress. The use of diaries is emerging as a putative tool to 'fill the memory gaps' and promote psychological recovery. In this review, we critically analyze the available literature regarding the use and impact of diaries for intensive care patients specifically to examine the impact of diaries on intensive care patients' recovery. Diversity of practice in regard to the structure, content, and process elements of diaries for intensive care patients exists and emphasizes the lack of an underpinning psychological conceptualization. The use of diaries as an intervention to aid psychological recovery in intensive care patients has been examined in 11 studies, including two randomized controlled trials. Inconsistencies exist in sample characteristics, study outcomes, study methods, and the diary intervention itself, limiting the amount of comparison that is possible between studies. Measurement of the impact of the diary intervention on patient outcomes has been limited in both scope and time frame. Furthermore, an underpinning conceptualization or rationale for diaries as an intervention has not been articulated or tested. Given these significant limitations, although findings tend to be positive, implementation as routine clinical practice should not occur until a body of evidence is developed to inform methodological considerations and confirm proposed benefits

An information and communications technology (ICT)-enabled method for collecting and collating information about pre-service teachers' pedagogical beliefs regarding the integration of ICT

This paper describes a method that utilized technology to collect and collate quantitative and qualitative data about pre‐service teachers’ use of networked technologies during a 12‐week undergraduate course, and the impact of this use on their pedagogical beliefs regarding the integration of information and communications technology (ICT). The technologies used captured and analysed students’ spoken and written communication while engaging in four synchronous online tasks, and also collected evaluation data from online interviews, surveys and diaries. The richness of data afforded by this ICT‐enabled method enabled the research to produce a rich narrative of how the students used the technology and provided evidence of a change in pre‐service teachers’ pedagogical beliefs during the course

Video diaries: : a discussion of their use for researching the learner experience in higher education

This is the accepted version of the following article: Amanda Jefferies, ‘Video diaries: a discussion of their use for researching the learner experience in higher education’, International Journal of Learning Technology, Vol 10 (3): 237-250, published by Inderscience Publishers, October 2015. The version of record is available online via doi: http://dx.doi.org/10.1504/IJLT.2015.072359This paper considers the rationale for using video diaries as a method of qualitative data gathering for research into students’ experiences of higher education (HE). In particular, the paper considers how video diaries have been employed for researching students’ views and attitudes to their own learning and development. The paper examines the literature on the purpose of reflective video diary research as the method has moved beyond its initial primary development in medical research and specifically into their use in HE. The particular benefits of personal video-diary compilation are considered in terms of the autonomy of the participant. A methodology for employing video diaries as a research method for data collection is discussed within the context of three case studies with undergraduate students at a UK university. The conclusions highlight the unique value of participant-generated video diaries for researching the nature of the student learning experience in HE.Peer reviewe

Development of food photographs for use with children aged 18 months to 16 years:comparison against weighed food diaries – The Young Person’s Food Atlas (UK)

Traditional dietary assessment methods, used in the UK, such as weighed food diaries impose a large participant burden, often resulting in difficulty recruiting representative samples and underreporting of energy intakes. One approach to reducing the burden placed on the participant is to use portion size assessment tools to obtain an estimate of the amount of food consumed, removing the need to weigh all foods. An age range specific food atlas was developed for use in assessing children’s dietary intakes. The foods selected and portion sizes depicted were derived from intakes recorded during the UK National Diet and Nutrition Surveys of children aged 1.5 to 16 years. Estimates of food portion sizes using the food atlas were compared against 4-day weighed intakes along with in-school / nursery observations, by the research team. Interviews were conducted with parents the day after completion of the diary, and for children aged 4 to 16 years, also with the child. Mean estimates of portion size consumed were within 7% of the weight of food recorded in the weighed food diary. The limits of agreement were wide indicating high variability of estimates at the individual level but the precision increased with increasing age. For children 11 years and over, agreement with weighed food diaries, was as good as that of their parents in terms of total weight of food consumed and of intake of energy and key nutrients. The age appropriate food photographs offer an alternative to weighed intakes for dietary assessment with children
