Toward a logical/physical theory of spreadsheet modeling
Tomás Isakowitz, Shimon Schocken, Henry C. Lucas, Jr.
Pages: 1-37
DOI: 10.1145/195705.195708
In spite of the increasing sophistication and power of commercial spreadsheet packages, we still lack a formal theory or a methodology to support the construction and maintenance of spreadsheet models. Using a dual logical/physical perspective,...

On modeling information retrieval with probabilistic inference
S. K. M. Wong, Y. Y. Yao
Pages: 38-68
DOI: 10.1145/195705.195713
This article examines and extends the logical models of information retrieval in the context of probability theory. The fundamental notions of term weights and relevance are given probabilistic interpretations. A unified framework is developed...

From text to hypertext by indexing
Airi Salminen, Jean Tague-Sutcliffe, Charles McClellan
Pages: 69-99
DOI: 10.1145/195705.195717
A model is presented for converting a collection of documents to hypertext by means of indexing. The documents are assumed to be semistructured, i.e., their text is a hierarchy of parts, and some of the parts consist of natural language. The...

Some inconsistencies and misidentified modeling assumptions in probabilistic information retrieval
William S. Cooper
Pages: 100-111
