Outline n n n Introduction ETANA-DL Demonstration New enhancements Tools for data integration Discussion

Problems n n n 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

Solution – our approach n n n 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 5 S theory to better understand the domain and design the systems and the supported services Using componentized frameworks: eliciting requirements, providing useful services

ETANA-DL Image Searching Service n 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

query image searching results

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

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

ETANA usability study n 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.

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

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

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