To facilitate accurate document searching, electronically accessible documents are provided with abstracts written in a highly constrained artificial grammar. The artificial grammar is capable of expressing the thoughts and information ordinarily conveyed in a natural grammar, but in a structured format that restricts the number of possible alternative meanings. Accordingly, while the grammar is clear in the sense of being easily understood by native speakers of the vocabulary and complex in its ability to express sophisticated concepts, sentences are derived from an organized vocabulary according to fixed rules. A query, preferably formulated in accordance with these rules, is employed by a search engine in the usual fashion. Due to the highly constrained meaning of the search query, and the likelihood that relevant documents have similar or matching abstracts in their headers, key-word searches are likely to identify the most relevant documents. |
