The oNLine System (NLS), which gave birth to virtually all subsequent human computer interfaces as well as the internet, was funded by ARPA.  Doug Engelbart credited Vannevar Bush’s imaginary Memex as an inspiration for the NLS work.  On February 4, DARPA announced interested in receiving abstracts for elements of a Memex.  (ARPA was renamed to DARPA in 1972 and 1996. )
The Memex solicitation identifies three technical areas in the Memex initiative:
1. Domain-Specific Indexing: web crawling, content discovery, information extraction
2. Domain-Specific Search: configurable interface for web content, query language development
3. Application: making use of indexing and search capabilities, system-level operation and deployment, use case development, requirements analysis, interface design, application hardening feedback
This is notable mainly since January 28′s post on this blog covered, point by point, Oneslate’s level of achievement in the capabilities that one academic suggested would be required for a system to live up to the alleged potential of a Memex system.
