In this study, the way of the automatic text categorization on web-based query was implemented. X2 methods based on the Supported Vector Machine were used to test the efficiency of text categorization on queries. This test is carried out by the model using the Synonymy List. 713 synonyms were extracted manually from the tested documents. As the result of this test, the precision ratio and the recall ratio were decreased by -0.01% and by 8.53%, respectively whether the synonyms were assigned or not. It also shows that the Value of F1 Measure was increased by 4.58%. The standard deviation between the recall and precision ratio was improve by 18.39%.

A taxonomic study of small mammals (Erinaceomorpha, Soricomorpha and Rodentia) was conducted in order to find out the scientific names which have been used in Korea. The synonymy of each species and taxonomical research was reviewed and confirmed in this study. The species names are rearranged based on recent studies. Among the various confused names, available names were adopted such as follows: C. shantungensis shantungensis known as Crocidura suaveolens; C. shantungensis quelpartis known as C. dsinezumi; Rattus tanezumi known as R. rattus, called black rat, roof rat and ship rat, respectively. Apodemus sylvaticus (Muridae, wood mouse) is excluded in the checklist based on indistinct previous records and ambiguous habitation on the Korean Peninsula, and neighbors. In addition, we provide a new Korean vernacular name for Myocastor coypus, called the "Nutria" in Korea. We reflect that several species are repositioned to other genera. A checklist of Korean small mammals and synonym list for each species is provided to avoid confusion of scientific names in Korea. In this study, the list of small mammals in Korea is arranged to 33 species, 20 genera, 8 families, and 3 orders.

Amynthas tralfamadore sp. nov. is described from the Mt Halla, Jeju Island biosphere exhibition housed at NIBR Incheon. This species' taxonomy is problematical since it is similar to Amynthas masatakae (Beddard, 1892) from Japan, itself previously reported from Korea and at one time associated with Amynthas campestris (Goto & Hatai, 1898) and A. parvicystis (Goto & Hatai, 1899), all three variously implicated in prior A. robustus (Perrier, 1872) along with Amynthas aspergillum (Perrier, 1872). Based on reinspection of the London lectotype of A. masatakae-here designated and sketched for the first time-the current solution is for maintenance of all five taxa separately. A closely-related Japanese species-Metaphire ryunome sp. nov.-is comparable to Korean Metaphire reisuiensis (Kobayashi, 1938) comb. nov. Another specimen was identified as Amynthas micronarius (Goto & Hatai, 1898), a new record for Korea. It matches the newly-designated neotype (Tokyo NMST An446) and an annotated synonymy is provided; however, erstwhile synonyms, Amynthas shimaensis (Goto & Hatai, 1899) and A. yamizoyamensis (Ohfuchi, 1935) combs. novae, are briefly redescribed and provisionally restored to the Japanese list. mtDNA COI-5P barcode analyses support species identifications.

A total of 56 genera and 101 species of the fly family Tephritidae have been previously recorded in Korea. As a result of an ongoing study of this family, I report the following ten additional species new to Korea: Actinoptera montana (Meijere, 1924), Actinoptera reticulata Ito, 1984, Campiglossa luxorientis(Hering, 1940), C. melanochroa (Hering, 1941), C. quadriguttata (Hendel, 1927), C. shensiana (Chen, 1938), Oxyna gansuica Wang, 1998, Tephritis jocaste Hering, 1953, Tephritis okera (Shinji, 1940), and Trupanea guttistella (Hering, 1951). Among the five genera involved here, the genus Actinoptera Rondani, 1871 is recognized for the first time in Korea. Therefore, 57 genera and 111 species are now officially recognized for the Korean tephritid fauna. For each newly recognized Korean species, I provide new Korean name, synonymy, taxonomic diagnosis and color photographs. When possible, I list the host records and discuss their intraspecific variability and sexual dimorphism.
