The existing electronic tagging system traces the location of a sex offender through communicating with GPS satellites and mobile phone base stations in order to prevent repeated crimes. However, the GPS satellite communication method does not work well in the interiors of downtown buildings or on the subways where it is difficult to receive satellite signals. In such cases, the location can be traced through communication with mobile phone base stations. But the distance between mobile phone base stations is several hundred meters, and as a result the margin of error for location tracing can be maximum of 2km in accuracy reduction. Take for example, if a kindergarten is located on the 2nd floor and a coffee shop and the sex offender are located on the 3rd floor in a 5-story building that is downtown, the existing electronic tagging system cannot trace the location of the sex offender as the GPS satellite communication does not work in the interior of the building and the exact floor that the sex offender is located on cannot be recognized through communication with mobile phone base stations. This occurrence is a big problem for the existing electronic tagging system, which is based on position recognition. Therefore, this study suggests a smart electronic tagging system that can monitor sex offenders by using a Ubiquitous Sensor Network in such extreme situations where position recognition is not possible.

A set of text database is indispensable to the probabilistic models for speech recognition, linguistic model, and machine translation. We introduce an environment to canstruct text databases : an automatic tagging system and a set of tools for lexical knowledge acquisition, which provides the facilities of automatic part of speech recognition and guessing.

This study aims to improve the access and retrieval of images and to find a way to effectively generate tags as a tool for providing explanation of images. To do this, this study investigated the features of human tagging and machine tagging, and compare and analyze them. Machine tags had the highest general attributes, some specific attributes and visual elements, and few abstract attributes. The general attribute of the human tag was the highest, but the specific attribute was high for the object and scene where the human tag constructor can recognize the name. In addition, sentiments and emotions, as well as subjects of abstract concepts, events, places, time, and relationships are represented by various tags. The tag set generated through this study can be used as basic data for constructing training data set to improve the machine learning algorithm.

Many studies using RFID which can identify the movement of targeted objects has been conducted actively. In this paper, we propose improved tagging method to check exactly the amount of fish feed by the aquaculture tank in a land-based aquaculture farm and design the RFID feeding system to perform auto feeding history. Also, we implement the prototype system which it includes development program for auto-identification and auto-recording and self-made RFID feeding cart equipped the weight device, RFID reader, control module and display device.

In this paper we describe a Korean part-of-speech tagging approach using resolution rules for individual ambiguous word and statistical information. Our tagging approach resolves lexical ambiguities by common rules, rules for individual ambiguous word, and statistical approach. Common rules are ones for idioms and phrases of common use including phrases composed of main and auxiliary verbs. We built resolution rules for each word which has several distinct morphological analysis results to enhance tagging accuracy. Each rule may have morphemes, morphological tags, and/or word senses of not only an ambiguous word itself but also words around it. Statistical approach based on HMM is then applied for ambiguous words which are not resolved by rules. Experiment shows that the part-of-speech tagging approach has high accuracy and broad coverage.

We propose a collaborative social tagging for eBook using external DSL approach. The goal of this paper is (1) to provide DSL by which authors can write HTML5 rich contents ebook and tag resources, (2) to make users enhance book by tagging resources easily, (3) to make readers read rich book easily regardless of their devices types, (4) to provide ebook resources of RESTful address style by which other system can identify self-descriptive resources of book. To achieve the goal, we provide Bukle DSL language by which author and users can author and enhance ebook with ease. As a domainspecific language Bukle provides a simple yet expressive language for authoring and tagging books that would otherwise be more difficult to express with a general purpose language. Further work includes visual DSL approach and tools by using that the unskilled users could tag book easily. In order that future work also includes text-to-visual DSL transform engine. UX research is also required to tag and to author book. To tackle the above questions we are looking at using visual notation focusing visual syntax.

A novel chromosomal gene tagging technique using a specific fragment of the fatty acid desaturase-like open reading frame (des-like ORF) from the tox-argK gene cluster of Pseudomonas syringae pv. phaseolicola was developed to identify Xanthomonas spp.released into the environment as biocontrol agents. X. campestris pv. convolvuli FB-635, a pathogen of Convolvulus arvensis L., (bindweed), was chosen as the organism in which to develop and test the system. A 0.52 kb DES fragment amplified from P. syringae pv. phaseolicola C-199 was inserted into pGX15, a cosmid clone containing a 10.3 kb Eco RI-HindIII fragment derived from the xanthomonadin biosynthetic gene cluster contained in plasmid pIG102, to create a pigG::DES insertion. The 10.8 kb EcoRI-BamHI fragment carrying the pigG:: DES insertion was cloned into pLAFR3 to generate pLXP22. pLXP22 was then conjugated into X. campestris pv. convolvuli FB-635 and the pigG::DES insertion integrated into the bacterial chromosome by marker exchange. Rifampicin resistant, tetracycline sensitive, starch hydrolyzing, white colonies were used to differentiate the marked strain from yellow pigmented wild-type ones. PCR primers specific for the unique DES fragment were used for direct detection of the marked strain. Result showed the marked strain could be detected at very low levels even in the presence of high levels of other closely related or competitive bacteria. This PCR-based DES-tagging system provides a rapid and specific tool for directly monitoring the dispersal and persistence of Xanthomonas spp.released into the environment.

This study was carried out to investigate the optimum tagging method of the abalone juvenile, Haliotis discus hannai in indoor culture system from May 2000 to January2001. Tagging methods were shell drilling, copper-wire tagging at the respiratory pore and nut gluing on the shell. The attachment rates of the shell showed high in the 2- and 3 cm bolt-nut tagged groups, about over $89.5\%$, whereas shell drilling groups on the shell were about $18.5\%$. The internal coating rates tagged with bolt-nut were over $96.6\%$, while those tagged with copper wire were less than $17.1\%$. Growths in the all marked and tagged experimental groups comparing with control groups were not significantly different (p>0,05). Survivals in all tagging groups except shell drilling and nut gluing groups in the 5 cm abalone were over $95\%, Accordingly, all juvenile groups were not affected by the tagging methods in terms of the growth and survival on the abalones. Based on these results, the micro bolt-nut tagging was the most effective method in abalone.

통계 기반 접근 방법을 이용한 품사태깅에서 태깅 정확도는 훈련 데이터의 양에 좌우될 뿐 아니라, 말뭉치가 충분할지라도 수작업으로 구축한 말뭉치의 경우 항상 오류의 가능성을 내포하고 있으며 언어의 특성상 통계적으로 신뢰할만한 데이터의 수집에도 어려움이 따른다. 훈련 데이터로 사용되는 말뭉치는 많은 사람들이 수작업으로 구축하므로 작업자 중 일부가 언어에 대한 지식이 부족하다거나 주관적인 판단에 의한 태깅 실수를 포함할 수도 있기 때문에 단순한 저빈도와 관련된 잡음 외의 오류들이 포함될 수 있는데 이러한 오류들은 재추정이나 평탄화 기법으로 해결될 수 있는 문제가 아니다. 본 논문에서는 HMM(Hidden Markov Model)을 이용한 한국어 품사 태깅에서 재추정 후 여전히 존재하는 말뭉치의 잡음에 인한 태깅 오류 해결을 위해 비터비 알고리즘적용 단계에서 데이터 부족과 말뭉치의 오류로 인해 문제가 되는 부분을 찾아내고 규칙을 통해 수정을 하여 태깅 결과를 개선하는 방안을 제안한다. 실험결과는 오류가 존재하는 말뭉치를 사용하여 구현된 HMM과 비터비 알고리즘을 적용한 태깅 정확도에 비해 오류를 수정하는 과정을 거친 후 정확도가 향상됨을 보여준다.

최근 소설 네트워크 서비스(Social Netwrok Services)를 활용한 소설 태깅 서비스에 대한 연구가 활발하게 진행 중이다. 특히 태그 기술을 이용한 협력적 태깅 시스템(collaborative tagging system)은 북마크, 문서, 사진, 동영상과 같은 웹 자원을 조직화하고 공유할 수 있는 수단으로 제공하고 있다. 그러나 광고 홍보 목적을 가진 스패머들은 콘텐츠와 관련 없는 태그를 달아 놓아 검색 키워드와 무관한 결과 값이 검색되어 웹 검색 서비스를 이용하는 사용자들에게 불편을 주고 있다. 따라서 본 연구에서는 콘텐츠와 태그의 연관성을 높이기 위해 태그에 일반 사용자가 유사도를 입력할 수 있는 추천 시스템을 적용하여 순위 조작 방지방법을 제안하였다.
