The next words are appended to the input phrase to create one or more predicted phrases. The predicted phrases are sorted, where the predicted phrases are sorted based on a similarity computation between the predicted phrases and the corpus of documents for the specific domain.

Abstract: Given a skeleton knowledge graph including first terms in respective nodes, wherein first terms in connected nodes have a predetermined relationship, an augmented knowledge graph is formed by a first computing device by extracting a second term from a domain corpus to form a term cluster linked with a respective node of the knowledge graph. The second term is associated with the first term of a respective node in the domain corpus while not meeting the predetermined relationship. A semantic feature between the second term and the associated first term is identified in the domain corpus and linked to the pair of the second term and the first term in the augmented knowledge graph. The augmented knowledge graph is useable by a second computing device, which may or may not be the same as the first computing device, to drive a conversation between a chatbot and user.

Abstract: A method for determining a fugitive emission factor (EF) and a leakage rate of a combustion source. For a combustion source capable of performing stack emission and fugitive emission, an organized EF, a fugitive EF, and a leakage rate of fugitive emission are respectively obtained through calculation based on material balance. The method solves the problem that it is impossible to collect a total amount of smoke and to quantify its volume in a field test and the problem that a conventional carbon mass balance (CMB) method cannot distinguish organized leakage from fugitive leakage. The method can be used not only for determining gas leaked from residential indoor stoves using coal, biomass, etc., but also for determining fugitive emissions from other sources, such as the amount of gas leaked to the surrounding environment through the body of a brick kiln in a brick and tile factory.
