A Tool for Exploratory Research

I suitable research context

I exploration of datasetsI visualization / distant reading let emerge patterns within data

I suitable if

I data are in KML formatI data have both time and space information attached to them

I KML allows for export of data from various sources intogeo-browser

I preparation of data is part of research processI needs to be informed by research questions

Limes :: Places (Gazetteer)

Limes :: Publications (Zenon)

Limes :: Research Questions

I which publications are related to a given place?

I what are the most/least studied places?

I how studies about the Limes developed over time?

I . . .

Mashable Data

I logic:

I get Limes places from Gazetteer (filter by tag)I for each place fetch related publications from ZenonI keep only places having 1 (or more) publicationsI display publications on map:

I space: Limes place they related toI time: publication date

I interoperable infrastructure

I RESTful APIs / JSONI shared identifiers for

I place namesI subject headings

Limes :: Gazetteer & Zenon mashup

permalink

1980s: 12 publications

1990s: 158 publications

Conclusions

I exploratory research

I visualization not useful in itself. . .I . . . only if it helps us to answer/formulate new research

questions

I serendipity through data visualization

I mashable data

I variety of formats for import/exportI importance of access to data via APIsI use of common/shared identifiers to link resources

I share
