Smart Qualitative Data: Methods and Community Tools for Data Mark-Up SQUAD

Louise Corti

IASSIST, Edinburgh May 2005


New qualitative data uk initiative
New qualitative data Data Mark-Up UK initiative

  • Demonstrator Scheme for Qualitative Data Sharing and Research Archiving scheme - QUADS

  • main aim of scheme to develop and promote innovative methodological approaches to the archiving, sharing, re-use and secondary analysis of qualitative research and data

    • models may be of temporary, local or thematic archiving

    • complement the ESDS Qualidata approach (traditional data archiving model)

    • exploit new or existing research collaborations locally, nationally or internationally

  • explore a range of new models for increasing access to qualitative data resources, and for extending the reach and impact of qualitative studies

  • draw primarily on existing qualitative research and data sets of a range of types but encourages researchers to explore the use of stored and shared video, visual and audio data sets

  • promote understanding of the benefits and challenges of emerging information and communication e-science technologies

  • aim to disseminate good practice in qualitative data sharing and research archiving

  • part of the ESRC's initiative to increase the UK resource of highly skilled researchers, and to fully exploit the distinctive potential offered by qualitative research and data

  • @£500,000 over 10 months: 6 awards – 5 demonstrators + 1 coordination


Squad aims
SQUAD Aims Data Mark-Up

  • collaboration between UK Data Archive, University of Essex and Language Technology Group, Human Communication Research Centre, School of Informatics, University of Edinburgh

  • Essex lead partner

  • 18 months duration, 1 March 2005 – 31 august 2006

  • 5 part-time staff split across sites = 1 FTE

    Aims:

  • to explore methodological and technical solutions for ‘exposing’ digital qualitative data to make them fully shareable and exploitable and to promote appropriate standards and tools

  • Precursors of data sharing and collaborative research practice and data analysis are to found in the methods and tools for documenting and representing data


Why do we need tools standards
Why do we need tools & standards? Data Mark-Up

  • to archive and web-enable high quality qualitative data in a way that faithfully represents its origins and context

  • to provide rich and full documentation that enables effective resource discovery (already do DDI first 3 levels)

  • to enable creative and exciting ways of exploring and visualizing data

    • from simple publishing of anonymised digital qualitative data

    • through mark-up to the ability to link qualitative data to other distributed data sources (e.g. audio-visual or geo-coded data sources)

  • the absence of appropriate tools and standards is inhibiting successful digitisation efforts

    • many popular qualitative collections are not yet even in digital format

    • "digitising" these collections is often merely providing an online catalogue of metadata

    • there is little community knowledge in this area about the use of standards (TEI not used in social science)


Prerequisites for making data shareable
Prerequisites for making data shareable Data Mark-Up

  • data are collected to a high standard

  • research methods and practices (including consent process) are fully documented

  • the context of the data collection and analysis is captured

  • the richness of the structure and features of data and are made available (use of mark-up)

  • the interrelationships between data and analyses (intra-project) are made available (issues of representation)

  • data are represented in intuitive, appealing and sensitive ways that satisfy the ethical and legal requirements to which they are bound


Main objectives
Main objectives Data Mark-Up

  • specify, test and propose an XML schema for storing and marking-up a broad range of qualitative data types

    • textual or audio-visual social science data

    • and for e-social science exploitations, i.e. grid-enabling data

    • ESDS Qualidata had developed draft DTD based on TEI)

  • investigate requirements for contextualising data (e.g. interview setting and interviewer characteristics), and develop standards for data documentation and common vocabularies

  • develop user-friendly (java-based) tools for semi-automating processes (using NLP technologies) already used to prepare qualitative data for digital archiving and e-science type exploitation

  • investigate non-proprietary tools for publishing and archiving XML marked-up data and study context - Qualitative Data Mark-up Tools (QDMT). Enable preservation of data structures and links to other objects

  • increase awareness and provide training with step-by-step guides and exemplars on the use of these tools and standards utilised


A uniform quali format
A uniform quali format Data Mark-Up

  • a uniform format for richly encoding qualitative research is necessary as it:

    • ensures consistency across datasets

    • supports the development of common web-based publishing and search tools

    • and facilitates data interchange and comparison among datasets

  • it could also enable data and linked products to be imported and exported directly into and out of CAQDAS packages, avoiding the reliance on just a single product, and offering the opportunity to share analytic workings outside the confines of the particular software

  • a draft but limited formal definition of a common XML vocabulary and Document Type Definition (DTD) based on the Text Encoding Initiative (TEI) for describing these structures has been prepared by ESDS Qualidata

  • but the important development of a common framework for marking up the content of qualitative datasets requires support and contribution from various sectors of the social science community:

    • data creators

    • qualitative data software developers

    • data archivists

    • end users

  • fortunately, the expansion of e-science funding is accelerating the need for such standards – exposure of ‘structured’ qualitative data to the web.


Marking up what
Marking up what? Data Mark-Up

  • spoken interview texts provide the clearest -and most common -example of the kinds of encoding features needed

  • three basic groups of features

    • structural features representing basic format: utterance, specific turn taker, other speech tags e.g. defining idiosyncrasies

    • structural features representing links to other data types created in the course of the research process (e.g. audio or video referencing points, researcher annotations)

    • structural features representing identifying information such as real names, company names, place names, temporal information


Solutions to qualitative data mark up with xml qualitative data mark up tools qdmt
Solutions to qualitative data mark-up with XML: Data Mark-Up Qualitative Data Mark-up Tools (QDMT)

  • systematic preparation of digital data : to create formatted text documents ready for xml output

  • mark-up of data to capture basic structural features of textual data: e.g. turn-takers, speakers and selected demographic details

  • advanced annotation or mark-up of data

    • automated information extraction of basic semantic information: inserting tags for real names and temporal references

    • automated anonymisation: replacing names with dummy forms, including co-references

    • geographic mark-up to enable data linking: identifying and applying geographic mark-up, and scoping researchers' needs for geo-linking

  • basic classification or thematic coding of textual data: for of efficient resource discovery rather than data analysis; will investigate linking into a domain ontology (e.g. social science thesaurus) - Key word assignment tool

  • contextual documentation to capture richness of the research methods, data collection and analytic interpretation and representation: will dovetail with Cardiff QUADS project to look at the interrelationships between complex intra-project data, annotations and context

  • exposure of annotated and contextualised qualitative data to the web: investigating publishing of above QDM XML outputs to ESDS Qualidata Online, opportunities for exchange within CAQDAS tools, etc.

Existing tools
Existing tools Data Mark-Up

  • Making use of unix-based community tools used in NLP fields

  • applications are for mining and summarising e.g. legal, pharmaceutical reports, news stories, web sites etc.

  • but not tested on for social science corpora yet – training data is limited

  • tools using named entity recognition and speech taggers will insert xml tags

  • others use stand-of annotation (x-link, x-pointer etc)

  • Currently unfriendly tools - need GUIs!


Relationship to esds qualidata
Relationship to ESDS Qualidata Data Mark-Up

  • ESDS Qualidata, through the UKDA, currently provides the ESRC RRB strategy for archiving, accessing and supporting users of qualitative research data

  • strong emphasis on

    • developing community standards for describing data/metadata

    • providing better study and data context to inform re-use

  • grant represents critical useful R&D funding for ESDS Qualidata who have no budget to do this normally

  • SQUAD outputs and tools will be used for in-house processing of qualitative data

  • and made available as shareable standards and tools for others archiving data
