Bushman OnLine Dictionary
The Bleek and Lloyd Collection is set of indigenous artefacts.
Project aims to integrate a collection of digital scans corresponding to a dictionary to the existing Bleek and Lloyd Collection.
Image-based dictionary matches a word to an image.
Image-based dictionary for indigenous languages – used as live reference.
Aim to integrate collection of digital scans as image-based dictionary.
Is it possible to create a reusable, generic archival system that allows users to access an image-based dictionary?
Key-features: Archive Collection Management
Lebogang Molwantoa Search and Browsing functionality
Sanvir Manilal Image-based translation.

Research Question tackled: Can we develop a useful and efficient
archival system for an image-based dictionary?
Archive management collection component of the project can be considered as back end to the system.
Archive is a repository for scanned images and associated metadata.
Extensible and allow easy update via API.
Size and complexity presents a challenge
Can we develop a useful and efficient archival system?
Efficient archive capable of processing and archiving large numbers of images efficiently.
Research Question: Can image based searching be done accurately and efficiently?
Needs to return correct results
Needs to return results in short amount of time
Subset of CBIR specifically for handwritten historical documents
Performs image matching on images of words
Used to find repeat occurrences of words in manuscripts
Look at features of word/phrase
Create signature for word/phrase based on feature vector
Insert signature into database
User selects word/phrase in collection
Signature is calculated
Signature is used to search for matches in archive
Accuracy?
Evaluation based on controlled tests as well as random tests
Key success will be the ability to accurately and efficiently provide image based translation
Requirements gathering UCT Fine arts
Iterative design and development Three prototyping phases Carrying out periodic evaluation with users
Final system integration Carrying out evaluation of the overall
system functioning and performance
Research question tackled: Can searching and browsing a visual
dictionary be done in an efficient and effective way?
Unique problem
A few techniques: Live Search Inexact pattern matching
Thumbnails Hyperlinks Scrollable list of words
Evaluation: Efficiency Performance Effectiveness Aesthetics
Fully working system with three key components Archive – Lebogang Molwantoa Tools for searching and displaying –
Sanvir Manilal Image matching tool – Kyle Williams
Reports, website, poster, reflections – Everyone
