WISERD

WISERD

• Major investment in research infrastructure in Economic and Social

Sciences across Wales

• Major innovations in qualitative, quantitative and mixed methods

• Establish flexible and integrated sets of data relating to Wales

• Strategy for generating research grant bids and sustainability

• Links with WAG, ONS and Local Authorities across Wales

• Links with Other Centres and Programmes in Cardiff

Emerging research

• Collaborative Qualitative GIS research project involving both GI professionals and qualitative researchers from backgrounds with little association with spatial literacy or mapping

• Attempt to understand the different geographies that policy makers make use of in their day-to-day work

• Context of Welsh devolution where some policy areas devolved to WG some still remit of Westminster

• Provide empirical support to theoretical concepts of relational space (Jones, 2009)

• GIS augmented traditional qualitative analytical methods

Interviews

• In-depth interview 120 stakeholders across 3 localities who have links to 8 policy areas

Crime, public space & policing Education and young people

Language, citizenship & identity Environment, tourism and leisure

Health, wellbeing and social care Economic development and regeneration

Housing and transport Employment and training

Transcipts

• Interviews recorded and transcribed by professional company

• Analysed in CAQDAS package (Atlas.ti)

• Parsed through qualitative meta-data generator using Web Services to geo-tag places and semantically tag words

• Place names geo-tagged with page, line number and word number in transcript

• Also, all transcripts manually geo-tagged to allow success of automated geo-tagging to be evaluated

Page 14: Mapping interview transcript records: theoretical, technical and cartographic challenges - Dr Scott Orford

Geo-tagging

• Place names in the transcripts identified and extracted with page and line number

• geo-tagged to a single point using the OS 1:50,000 scale gazetteer

Problems of geo-tagging

place names (Southall, et al. 2011)

• Identifying place names in transcripts

• Place name spelling mistakes in transcripts (esp Welsh place names)

• Vernacular names with no official geography

• Confounding place names with different geographical features

• Multiple places with the same name (geotag)

Page 16: Mapping interview transcript records: theoretical, technical and cartographic challenges - Dr Scott Orford

GeoVisualization

• Geo-visualization is an important aspect of Qualitative GIS and a function that has been used to justify and promote its use (Knigge & Cope, 2009)

Spatial Metrics

• GIS allows the construction of basic spatial metrics

• Can augment quantitative measures generated through analysis of coding of interview transcripts

• Provide support for discursive narratives of geographical themes in transcripts

Discussions • QGIS negotiate issues such as data sharing, confidentiality,

disclosure and what can and cannot be presented to people outside of the team.

• Added value to conventional qualitative analysis

• Value of the spatial metrics that could not be created in the CAQDAS

• Some spatial patterns uncovered in CAQDAS analysis but only treated discursively

• Cannot analyse or interpret maps / spatial metrics in isolation of transcripts or context of interview -

complimenting qualitative research (mixed methods) • What is relevant in the geo-tagged data

Future Research

• Analysis of automated geo-tagging software

• Development of non-disclosive cartographic techniques

• Further analysis of maps and spatial metrics and how they can be interpreted meaningfully in the context of interviews

• EQUALISA - transcript mapping and exploratory tool
