Document ranking on weight-partitioned signature files
Dik Kun Lee, Liming Ren
Pages: 109-137
DOI: 10.1145/226163.226164
A signature file organization, called the weight-partitioned signature file, for supporting document ranking is proposed. It employs multiple signature files, each of which corresponds to one term frequency, to represent terms with different...

Using local optimality criteria for efficient information retrieval with redundant information filters
Neil C. Rowe
Pages: 138-174
DOI: 10.1145/226163.226165
We consider information retrieval when the data—for instance, multimedia—is computationally expensive to fetch. Our approach uses “information filters” to considerably narrow the universe of possibilities before...

TROLL: a language for object-oriented specification of information systems
Ralf Jungclaus, Gunter Saake, Thorsten Hartmann, Cristina Sernadas
Pages: 175-211
DOI: 10.1145/226163.226166
TROLL is a language particularly suited for the early stages of information system development, when the universe of discourse must be described. In TROLL the descriptions of the static and dynamic aspects of entities are integrated into object...

Computerized performance monitors as multidimensional systems: derivation and application
Rebecca A. Grant, Chris A. Higgins
Pages: 212-235
DOI: 10.1145/226163.226167
An increasing number of companies are introducing computer technology into more aspects of work. Effective use of information systems to support office and service work can improve staff productivity, broaden a company's market, or dramatically...
