<p><strong>Program Overview</strong></p> <p>SOLAR (<em>S</em>emantically <em>O</em>riented <em>L</em>exical <em>AR</em>chive) was a lexical resource developed by the System Development Corporation (SCR) in Santa Monica, California in the 1970s (Diller and Olney 301). It was primarily distributed via the ARPA Network, with copies available by request for those without access to the network (Diller and Olney 310).</p> <p>According to Timothy Diller and John Olney of SCR, SOLAR \"is designed to permit a researcher to access a broad range of semantic data, all keyed to individual English words\" (Diller and Olney 301). SCR built in that breadth with the aim of making SOLAR relevant across fields, such as theoretical linguistics, philosophy of language, second language instruction and automated language processing (301). According to Diller and Olney in their article \"SOLAR (A <em>S</em>emantically <em>O</em>riented <em>L</em>exical <em>AR</em>chive): Current Status and Plans,\" published in 1974 prior to SOLAR's release,</p> <p style=\"margin-left: 30px;\">The SOLAR project is beginning to function both as a lexical information center and as a source of new lexical data. As an information center, it provides insightful descriptions of selected English words extracted from the technical literature of several fields and formatted for machine processing. As a source of new lexical data, it offers collocational features, semantic fields, definitional expansions within a designated set of words, and keyword-in-context materials derived by processing machine-readable transcripts <em>of Webster's Seventh New Collegiate Dictionary (W7)</em>, <em>Roget's International Thesaurus</em> and other text corpora. (Diller and Olney 301-302).</p> <p>Rather than being a lexicon itself, it offered a series of information-rich source files for constructing a lexicon (Diller and Olney 302). It was made up of seven files:</p> <p style=\"margin-left: 30px;\">File 1: Semantic Analysis</p> <p style=\"margin-left: 30px;\">File 2: Explanatory Notes for the Descriptive Constants Used in the Semantic Analyses</p> <p style=\"margin-left: 30px;\">File 3: Conceptual Analysis of Notions Involved by the Descriptive Constants</p> <p style=\"margin-left: 30px;\">File 4: Collocational Features Correlated with Particular Word Senses</p> <p style=\"margin-left: 30px;\">File 5: Semantic Fields</p> <p style=\"margin-left: 30px;\">File 6: Definitional Expansions</p> <p style=\"margin-left: 30px;\">File 7: Contexts of Occurrence (Diller and Olney 302-303)</p> <p>It also included two supplementary files, a Word Index and a Bibliography (Diller and Olney 309). Within this collection of files, SOLAR integrated data derived from relevant papers, presented in according to the wishes of the authors wherever possible (309).</p> <p>Diller and Olney summarized SOLAR as a resource</p> <p style=\"margin-left: 30px;\">designed to provide convenient access to semantic and conceptual analyses proposed by linguists, anthropologists, psychologists, philosophers and computer scientists, as well as to semi-processed, formatted data extracted from dictionaries, thesauri, and textual corpora.
