Tiresias: The Ancient Mediterranean Religions Source Database
Tiresias: The Ancient Mediterranean Religions Source Database
Tiresias: The Ancient Mediterranean Religions Source Database provides
access to references to ancient texts according to topic, mostly on
religion, c. -800 BCE to 800 CE in the Mediterranean area. In some
cases, direct access to full text is also available. Topic tagging is
based on existing subject indices from scholarly books, allowing highly
detailed topic resolution. The site is in development, and currently
includes 4,729,588 keyed to 53,361 subjects.
The construction of the database is based on the following method.
Many research volumes in ancient history are published with two indices:
one for subjects, topics or terms, and one for ancient text references
(the latter is also known as an index locorum). Using these
indices, each page of the indexed book can be identified as relating to
specific subjects as well as specific ancient texts, indicating with a
certain probability that these text references can be tagged as related
to these subjects. In order to bring this probability closer to 100%, we
assess the overlap from a number of books of this connection between
text reference and subject. These tags are combined to create a general
database of subjects of ancient texts. The database is thus based on
existing expert-made indices, unified and assisted by digital means.
The results for each search are divided into three: highly validated results, where the reference is tagged with the subject in more than one book; validated results, where the reference is tagged with the subject only in one book, but more than once; and non-validated results, where the reference is tagged with the subject only once, in one book.
The database includes general subjects, ideas, names and places,
almost all in English; the subjects are the same you would find in a
good subject index of a book.
The site attempts to provide full-text (in source language and
English) for highly validated results. Full texts for Hebrew Bible and
rabbinic texts is kindly supplied by Sefaria; for Greek and Latin texts, by Perseus Scaife, for the Quran, by Tanzil.net.
The site is part of a digital humanities research project
investigating innovative methods for text topic retrieval, conducted by Moshe Blidstein of the General History Department and the Haifa Center for Mediterranean History and Daphne Raban, the Department of Information & Knowledge Management, both at the University of Haifa.
