본 논문에서는 영화명, 도서명, 음악명 등의 제목 개체명 인식을 위한 새로운 방법에 대해 기술한다. 제목 개체명은 개체명 내부에 기존 MUC에서 분류한 인명, 지명, 기관명 등과 같은 일반적인 개체명과는 달리, 철자 자질 등 내부 자질을 사용하기 어려우며, 제목 개체명 부착 말뭉치가 없기 때문에 기존 연구에서 좋은 성능을 보인 방법들을 적용하기는 힘들다. 이러한 문제를 해결하기 위해 본 논문에서는 원시 말뭉치에서 자동으로 구축한 문맥 패턴 정보와 개체명 사전을 사용하여 제목 개체명을 인식하는 방법을 제안한다. 패턴과 제목 개체명 사전 구축을 위해, 사전 정보를 이용한 패턴 확장과 이렇게 구축된 패턴 정보를 사용한 사전 확장 단계를 반복 수행하여 문맥 패턴과 제목 개체명 사진을 점진적으로 증가시키는 방법을 사용하였으며, 이러한 정보가 제목 개체명 인식에 도움이 됨을 실험적으로 입증하였다.

A named entity recognition method is used to improve the performance of information retrieval systems, question answering systems, machine translation systems and so on. The targets of the named entity recognition are usually PLOs (persons, locations and organizations). They are usually proper nouns or unregistered words, and traditional named entity recognizers use these characteristics to find out named entity candidates. The titles of books, movies and TV programs have different characteristics than PLO entities. They are sometimes multiple phrases, one sentence, or special characters. This makes it difficult to find the named entity candidates. In this paper we propose a method to quickly extract title named entities from news articles and automatically build a named entity dictionary for the titles. For the candidates identification, the word phrases enclosed with special symbols in a sentence are firstly extracted, and then verified by the SVM with using feature words and their distances. For the classification of the extracted title candidates, SVM is used with the mutual information of word contexts.

In bibliographic data, the use of personal names to indicate authors makes it difficult to specify a particular author since there are numerous authors whose personal names are the same. Resolving same-name author instances into different individuals is called author resolution, which consists of two steps: calculating author similarities and then clustering same-name author instances into different person groups. Author similarities are computed from similarities of author-related bibliographic features such as coauthors, titles of papers, publication information, using supervised or unsupervised methods. Supervised approaches employ machine learning techniques to automatically learn the author similarity function from author-resolved training samples. So far however, a few machine learning methods have been investigated for author resolution. This paper provides a comparative evaluation of a variety of recent high-performing machine learning techniques on author disambiguation, and compares several methods of processing author disambiguation features such as coauthors and titles of papers.

This paper proposes an automatic method for discovering cross-lingual links from English Wikipedia documents to Korean ones in order to increase connectivity among vast web resources. Compared to the existing methods roughly estimating link probability of phrases, candidate anchors are selected from English documents by using various information such as title lists and linking probability extracted from Wikipedia dumps and the results of named-entity recognition, and the anchors are translated into Korean words, and then the most suitable Korean documents with the words are selected as cross-lingual links. The experimental results showed 0.375 of MAP.

This study proposes a novel reverse N-Gram approach to overcome the limitations of traditional N-Gram methods and enhance performance in building an entity dictionary specialized for the healthcare sector. The proposed reverse N-Gram technique allows for more precise analysis and processing of the complex linguistic features of healthcare-related big data. To verify the efficiency of the proposed method, big data on healthcare and digital health announced during the Consumer Electronics Show (CES) held each January was collected. Using the Python programming language, 2,185 news titles and summaries mentioned from January 1 to 31 in 2010 and from January 1 to 31 in 2024 were preprocessed with the new reverse N-Gram method. This resulted in the stable construction of a dictionary for natural language processing in the healthcare field.

This study concerns of how the Qing dynasty overcame the national inferiority on the process of the Ming-Qing war in the East Asia during the early 17th century. Historically the Qing came forward in succession the total 12 Emperors whose posthumouses were recorded according to a respective independent system. These studies will be commented the alliance between Manchurian and Mongolian tribes. As the researching result, it will be commented that the Qing's emperors possessed the names of the Emperor of Han's race, Khan of Mongolian tribe, Han of Manchurian clan at the same time. Furthermore in other to follow the war against the Ming dynasty the Qing dynasty promoted positively the strategic alliance through the marriage connection with Mongolian royal family. And the Qing dynasty succeeded in organizing the Military Eight Banners so that Qing dynasty could utilize the reorganized social civilian groups into the avaliable groups to the battle. Thus this Eight Banners were comprehended all members who were not only the Mongolian clans allianced but also the submitted soldiers from the Ming in the war.

An author of a paper is represented as his/her personal name in a bibliographic record. However, the use of names to indicate authors may deteriorate recall and precision of paper and/or author search, since the same name can be shared by many different individuals and a person can write his/her name in different forms. To solve this problem, it is required to disambiguate same-name author names into different persons. As features for author resolution, previous studies have exploited bibliographic attributes such as co-authors, titles, publication information, etc. This study attempts to apply email addresses of authors to disambiguate author names. For this, we first handle the extraction of email addresses from full-text papers, and then evaluate and analyze the effect of email addresses on author resolution using a large-scale test set.
