1- Morning session
About letter shapes - Is there any way to deal with statistical letter shapes? Melissa’s work did build statistical models of letter shapes for the Vindolanda ink tablets, based on positional probabilities within a character box. Another statistical modeling method would be by Principal Component Analysis, provided that enough samples are available. One question is then: “How much do letter shapes differ between ink tablets and incised tablets?”, and also “How could one ’compensate’ for the shapes not represented in the statistical model?” ’Compensating’ isn't quite the right term; what we want is in fact to inform and feed the database (and the model) with the newly found instances of letter shapes as well as consult it. For example in the case of the Frisian tablet (shown during the presentations), dated as a 1st Century AD tablet, a quite unique palaeography was found; ‘A’ as shaped in the document, would not have been identiﬁed as ‘A’s according to our current knowledge of shapes of ‘A’s in 1st Century AD Old Roman Cursive.About ontology - Percepts were deﬁned as ‘elementary perceptions’ that are already to some level an interpretation. How does that ﬁt into an ontology? An ontology is seen here as a kind of ‘super’-data-structure, that allows to separate content from the domain-specific structure as well as characterize relationships between ’objects’ in the ontology.
About expertise - The problem of expertise was pointed out. Experts are notoriously bad at analysing what they do and they tend to “jump to conclusions”. With that respect, it was suggested that observing non-specialists undertaking the tasks the experts do might be a valuable source of information and help decompose cognitive processes that are ‘built-in black-boxes’ in experts.
About other kinds of imaging - Spectral imaging is a very useful tool when dealing with ink texts. It is the chemical composition of the inks that provokes a reaction (or not) to speciﬁc wave-lengths of light. That kind of signal ampliﬁcation is bound to be unfruitful for incised texts – unless the incising tool left substantial (despite residual) traces of itself in the incisions. Shadow-stereo is a different way to amplify the original signal, in that it accentuates the features of the text by casting shadows and projecting highlights.[...]
2- Afternoon session
About using and building knowledge bases - Perseus was cited as a database that would be useful to link up to the ISS, in addition to the Vindolanda knowledge base, which is being put together. Regarding this knowledge base, lemmata were conﬁrmed as one of the search criteria for word searches; the problem of spelling and how an index represents misspelling was also evoked, as well as evolving (!) Latin grammar.
