Abstract: 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, keyword searches are likely to identify the most relevant documents.

Abstract: Language translation is accomplished by representing natural-language sentences in accordance with a constrained grammar and vocabulary structured to permit direct substitution of linguistic units in one language for corresponding linguistic units in another language. Preferably, the vocabulary is represented in a series of physically or logically distinct databases, each containing entries representing a form class as defined in the grammar. Translation involves direct lookup between the entries of a reference sentence and the corresponding entries in one or more target languages.
