The document summarizes the WebART project which aims to develop new methods and tools for researching web archives. It describes several data digging workshops conducted on the KB web archive dataset using various analysis tools. The workshops revealed researchers' interest in topic modeling over time but also limitations of current tools. The project aims to build more customizable, "research engine" tools that can support complex queries, analysis and result sharing for web archive research.

37. •New Media researchers’ interests:
• “derive periodizations of the Web” (Web history)
• “source hierarchy” (dominant sources in archive)
• “keyword uptake” (terms over time)
• e.g.‘geenstijl language in archive’
• “accidental”/“incidental” archiving
• e.g.‘the guilty pleasures of the Web of innocence’

42. Analysis (1)
• studying the ‘archive’ vs. the ‘archived content’
• researchers’ (un)familiarity with temporal (archive)
search
• “conditioned” to Google-style searching
• high demand for export functions and aggregation
features

43. Analysis (2)
•“data is still a crucial factor”
• quantity & quality: inherent incompleteness &
inconsistencies
• not always clear what’s in & what’s out
• crawl settings (e.g depth), temporal gaps
• “researchers always want what isn’t there”

45. A step further...
•Build customizable systems, or,
toolmakers’ tools
•Provide building blocks

46. A step further...
use “Hadoop” computing power to build custom dataset, perform high-level analysis, etc.

47. New tools: examples
•select,“clean”, filter & process dataset
•employ complex queries & search strategies
•search, summarize, aggre-
gate & share
