We present an algorithm for aligning texts with their translations that is based only on internal evidence. The relaxation process rests on a notion of which word in one text corresponds to which word in the other text that is essentially based on the similarity of their distributions. It exploits a partial alignment of the word level to induce a maximum(More)

We introduce a framework for access/action control which shifts the emphasis from the participants to their relationships. The framework is based on a communication model in which participants negotiate the mutually agreed-upon boundary conditions of their relationships, and create social reference points by encapsulating them in compact "communication(More)
We outline the five main research thrusts of the Stanford Digital Library project, and we describe technical details for two specific efforts that have been realized in prototype implementations. First, we describe how we employ distributed object technology to cope with interoperability among emerging digital library services. In particular, we describe(More)
The Stanford InfoBus is a prototype infrastructure developed as part of the Stanford Digital Libraries Project to extend the current Internet protocols with a suite of higherlevel information management protocols. This paper surveys the five service layers provided by the Stanford InfoBus: protocols for managing items and collections (DLIOP), metadata(More)
People keep pieces of information in diverse collections such as folders, hotlists, email inboxes, newsgroups, and mailing lists. These collections mediate various types of collaborations including communicating, structuring, sharing information, and organizing people. Grassroots is a system that provides a uniform framework to support peopleÕs(More)
People currently use a disparate set of systems such as email, newsgroups, hypermail, shared Web hotlists, hierar– chical indexes, etc. for activities which oflen cut across the boundaries implicit in each of these systems. Grassroots is a system that provides a uniform user-conceptual model to functionalities currently found in such systems, while not(More)
As part of the Stanford Digital Libraries Project, we have prototyped a novel architecture for security and access control in heterogeneous, networked environments. Conceptually, this architecture recasts security issues from an “information access” metaphor into a “relationship management” framework and uniformly applies a contracting model.(More)
