The first task is to develop an ontology (named OMP), which relates to key\u2010properties and key\u2010members of objects described in words\/terms of English vocabulary. Its training methodology is also a hybrid, rule\u2010based with proposed patterns and statistical\u2010based solution for selecting the best candidates from TREC English corpus. The second is proposals for mechanisms not only to look for relative result in the ontology OMP to complete and expand user's entered query\/noun phrase, but also to expand the search progress by linking the OMP ontology to indexes of information retrieval system. Especially, the base of these two tasks is our proposal for four kinds of semantic relationship of words.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>Several semantic relationships among words in vocabulary has been introduced and currently used in WordNet to represent the system of semantic networks. In another way, our analyzing for words in English vocabulary found that there are some kinds of semantic dependency in some cases for part(s) of a noun phrase, and it can be represented in grammar noun phrase syntax. That affects not only the proposed approach of ontology OMP development via identifying four kinds of semantic relationship and organizing its structure including core element types such as object and key\u2010member and key\u2010property, but also ontology training mechanism and solutions of query expansion by adding extended correspondent words (based on that relationship) to original query.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Research limitations\/implications<\/jats:title><jats:p>In initial iteration, the approach is applied for English query only with limited size of ontology OMP and dependency on grammar rules\u2010based in creating patterns to extract data from corpus. For future research, applications for other languages (Vietnamese, Chinese \u2026) with sharp focus on improvement of ontology training quality\/quantity and query expansion precision are primary targets.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Practical implications<\/jats:title><jats:p>The developed ontology OMP can be shared as a support for other applications such as semantic data extraction or semantic information retrieval in other researches.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>This paper fulfils an approach of ontology\u2010based query expansion and theoretical definitions of semantic relationship among words.
