A multi-lingual indexing and search system performs tokenization and stemming in a manner which is independent of whether index entries and search terms appear as words in a dictionary. During the tokenization phase of the process, a string of text is separated into individual word tokens, and predetermined types of tokens are eliminated from further processing. The stemming phase of the process reduces words to grammatical stems by removing known word-endings associated with the various languages to be supported. Known word endings are removed from the word tokens without any effort to guarantee that the remaining stem is contained in a dictionary. In a preferred implementation, the stemming process is only applied to nouns.

A cylindrical casing (18) has first and second ends (33 and 31), the first end (33) being closed. The casing (18) encloses an accelerant (22) disposed adjacent the first end (33), at least one stemming mechanism (21), and a fuse (14 or 14′) extending from the accelerant (22) out of the second end (31) of the cylindrical casing (18). The cartridge (12) is made of a rupturable cylindrical casing (18) with accelerant (22) and self-stemming mechanism (22) inserted therein. A method of breaking hard (R) materials involves detonating a self-stemming cartridge (12) disposed in a borehole (B).

The invention discloses consolidation water stemming for blasting blockage, which is formed in such a way that mixed powder is placed in a bag body, and is sealed and soaked in water, wherein the mixed powder comprises the following components in part by weight: 10-15 parts of attapulgite, 6-12 parts of chlorinated lime, 3-5 parts of gypsum, 1-3 parts of resin sweller and 0.1-0.4 part of sodium dodecyl sulfate; and the bag body is made of permeable papers. The consolidation water stemming has the advantages of simplicity and convenience in operation and low production and use cost; and the water curtain formed after explosive explosion can play a role of settling dust, degrading poisonous and harmful gas, dampening flame, reducing temperature and the like, and particularly, greatly reducing risks caused by methane gas accidents.

The invention discloses an English word weighed positive-negative relevancy pattern excavation method for fusing item weights and frequentness. The method comprises the steps of firstly conducting preprocessing of removing stopwords, extracting stems, calculating feature word weights and the like on a to-be-excavated English text dataset to construct an English text index library and a feature word library, adopting a weighted support calculation method for fusing the item weights and the frequentness and a support-relevancy evaluation framework to excavate a feature work weighed positive itemset and a negative itemset and constructing a positive itemset library and a negative itemset library item, adopting a support-lift-confidence evaluation framework to excavate an inter-word weighed positive-negative relevancy rule pattern and constructing a feature word weighed positive rule pattern library and a negative rule pattern library. According to the English word weighed positive-negative relevancy pattern excavation method for fusing the item weights and frequentness, the insufficiency of an existing weighed relevancy pattern excavation technology can be overcome, the item weights and the frequentness are effectively fused, a more practical and more reasonable text feature word positive-negative relevancy rule pattern is excavated, and by applying the inter-word relevancy modesto the field of query expansion, the performance of text information retrieval can be improved.
