Instruct: Identify the main and secondary category of Arxiv papers based on the titles and abstracts
Query: Archaeology in the Digital Age: From Paper to Databases   Research units in archaeology often manage large and precious archives
containing various documents, including reports on fieldwork, scholarly studies
and reference books. These archives are of course invaluable, recording decades
of work, but are generally hard to consult and access. In this context,
digitizing full text documents is not enough: information must be formalized,
structured and easy to access thanks to friendly user interfaces.
