4. Outline • Introduction • ETANA-DL Demonstration • New enhancements • Tools for data integration • Discussion

5. Problems • Delay in publication of primary archaeological data • Lack of sustainable solutions to long-term preservation of valuable information • Lack of services useful to the archaeology community, including “traditional DL services” • Difficulty in understanding complex archaeological information systems • Difficulty in requirements elicitation for archaeological systems • Interoperability among heterogeneous archaeological systems

6. Solution – our approach • Applying and extending Digital Library (DL) techniques to solve the following problems: making primary data available, data preservation, and interoperability • Modeling archaeological information systems using 5S theory to better understand the domain and design the systems and the supported services • Using componentized frameworks: eliciting requirements, providing useful services

31. ETANA-DL Visualization Service: EtanaCMV • Visual browsing interface for ETANA-DL based on Coordinated Multiple Views • Use distinct panels to allow flexible browsing across multiple dimensions • Bars in each panel denote the various categories in each dimension

32. site organization object type time period hierarchy highlighted categories are synchronized

38. ETANA-DL Image Searching Service • Content-Based Image Search Component • Search for similar DL objects based on image contents • Feature vectors are extracted from query image using the border/interior pixel classification image descriptor

43. query image searching results

44. Progress so far • Integrated pottery collection from Umayri • Replaced ODL-Search with Lucene Search Engine • Added: reporting feature, ETANA CMV, image retrieval service • ETANA usability study

45. ETANA usability study • Conducted a usability study with CS undergraduate seniors • Conducted a usability study with archaeology experts at Vanderbilt • Both conducted in computer labs • Participants didn’t have audio for tutorial

46. ETANA usability study • Some general observations • CS students completed the study in an average of 25 minutes. • CS students completed most tasks accurately. • For both groups, average time on each task decreased as time progressed in the study. • Archaeologists who were able to attempt all tasks did most tasks accurately.

48. Metadata harvesting Madaba Lahav Nimrin Umayri The World According to OAI Service Providers Searching Browsing Comparison Visualization … … Data Providers

49. Data and Service Providers • Data Providers – YOUR PROJECT • possess metadata and share it (internally / externally) • via well-defined OAI protocols (e.g., database servers) • Service Providers – ETANA-DL • harvest data from Data Providers • provide higher-level services to users

50. Why be an OAI Provider? • Speed up publication • Long-term preservation • Do not need to worry about providing services
