Etter å ha avlagt magistergrad i filosofi ved Universitetet i Trondheim i 1984 ledet jeg Det norske Wittgensteinprosjektet, før jeg i 1990 tok initiativ til opprettingen av Wittgensteinarkivet ved Universitetet i Bergen, som jeg ledet frem til publiseringen av Wittgenstein's Nachlass: The Bergen Electronic Edition (Oxford University Press, 2000, ISBN-10: 0192686917). Dette var den første fullstendige utgaven av Ludwig Wittgensteins etterlatte skrifter, og en av de første digitale tekstkritiske utgavene i sitt slag.

Etter den tid har jeg arbeidet filosofisk så vel som tekstteknologisk med metoder for representasjon, bearbeiding og analyse av dokumenter, samt spørsmål om deres ontologiske og epistemologiske status. Tekstkoding og transkripsjon er sentrale tema i dette arbeidet, som har to fokusområder:

• Identitetsbetingelser og likhets-mål for tekster generelt, og for elektroniske dokumenter spesielt.
• Representasjon, bearbeiding og analyse av komplekse dokumenter med overlappende, diskontinuerlige, uordnede eller alternativt ordnede elementer.
