With the recent advances in information retrieval, cross-media retrieval has been attracting lot of attention, but several issues remain problems such as constructing effective correlations, calculating similarity between different kinds of media objects. To gain better cross-media retrieval performance, it is crucial to mine the semantic correlations among the heterogeneous multimedia data. This paper introduces a new method for cross-media retrieval which uses ontology to organize different media objects. The experiment results show that the proposed method is effective in cross-media retrieval.

본 논문에서는 대화에서 그래프 기반 키워드를 추출하는 방법을 제안한다. 대화의 특성상 길이가 짧고, 생략이 많아 키워드 간의 연결 정도를 판단하기 힘들다. 이를 보완하기 위해 본 논문에서는 과거의 개인 대화 정보를 활용한다. 과거 대화 정보는 시간의 흐름이 반영된 현재 대화가 이뤄지기 전 말하고 듣는 것을 지칭하며, 이를 활용함으로써 개인화된 키워드를 발견할 수 있게 도와준다. 키워드 추출에 있어 현재 대화에서만을 고려하는 기존 연구와 달리, 제안한 방법은 앞서 구축된 과거 정보를 활용하여 그래프를 확장한 후 키워드를 추출한다. 실험을 통해 제안하는 방법이 베이스라인보다 현재 문장을 잘 반영할 수 있는 키워드를 추출함을 보인다.

This study does a qualitative and quantitative analysis of how music by humming is being used by music educators in the classroom. Music by humming is part division of music information retrieval. In order to define what a music information retrieval system is first I need to define what it is. Berger and Lafferty (1999) define information retrieval as "someone doing a query to a retrieval system, a user begins with an information need. This need is an ideal document- perfect fit for the user, but almost certainly not present in the retrieval system's collection of documents. From this ideal document, the user selects a group of identifying terms. In the context of traditional IR, one could view this group of terms as akin to expanded query." Music Information Retrieval has its background in information systems, data mining, intelligent systems, library science, music history and music theory. Three rounds of surveys using question pro where completed. The study found that there were variances in knowledge, training and level of awareness of query by humming, music information retrieval systems. Those variance relationships where based on music specialty, level that they teach, and age of the respondents.

As technology in a computer hardware and software advances, efficient information retrieval from multimedia database gets highly demanded. Recently, it has been actively exploited to retrieve information based on the stored contents. However, most of the methods emphasize on the points which are far from human intuition or emotion. In order to overcome this shortcoming , this paper attempts to apply interactive genetic algorithm to content-based image retrieval. A preliminary result with subjective test shows the usefulness of this approach.

The dynamic nature of the World Wide Web challenges Information Retrieval System to find information relevant and recent. Intelligent agents can complement the power of search engines to deal with this challenge. In this paper, we explain in manner of building Information Retrieval System based on intelligent agent technology. We present a tool called Websearcher. It was performed in Java environment. The object-oriented nature of Java and built-in facilities for multi-thread decreased our implementation effort. A modular software design makes it easy to configure the system for various experiments.

A great deal of research has been made to model the vagueness and uncertainty in information retrieval. One such research is fuzzy ranking models, which have been showing their superior performance in handling the uncertainty involved in the retrieval process. In this study we develop a new fuzzy ranking model based on the user preference. Through the experiments on the TREC-2 collection of Wall Street Journal documents, we show that the proposed method outperforms the conventional fuzzy ranking models.

웹과 같은 일반 영역을 대상으로 문서를 검색할 때 사용자의 질의 구성은 정보검색 효과에 큰 영향을 준다. 본 논문에서는 일반 사용자들이 웹에서 다언어 문서 검색을 효과적으로 수행할 수 있도록 다언어 지식베이스 기반의 지능형 정보검색 방법을 제안한다. 지식베이스로부터 추론된 지식은 사용자의 연상 작용을 도와 질의를 용이하고 정확하게 구성하여 효과적인 다언어 정보검색을 수행할 수 있도록 한다. 본 논문에서는 이러한 지식베이스 기반의 질의 변경 알고리즘을 개발하고 이를 한국어와 영어 웹 문서를 대상으로 실험하였다. 실험 결과 제안된 질의 변경 알고리즘은 다언어 문서 검색에서 지식베이스를 사용하지 않은 경우에 비해 매우 효과적임을 알 수 있었다.

At present, the Content-Based Image Retrieval (CBIR) system has become a hot research topic in the computer vision field. In the CBIR system, the accurate extractions of low-level features can reduce the gaps between high-level semantics and improve retrieval precision. This paper puts forward a new retrieval method aiming at the problems of high computational complexities and low precision of global feature extraction algorithms. The establishment of the new retrieval method is on the basis of the SIFT and Harris (APISH) algorithm, and the salient region of interest points (SRIP) algorithm to satisfy users' interests in the specific targets of images. In the first place, by using the IPDSH and SRIP algorithms, we tested stable interest points and found salient regions. The interest points in the salient region were named as salient interest points. Secondary, we extracted the pseudo-Zernike moments of the salient interest points' neighborhood as the feature vectors. Finally, we calculated the similarities between query and database images. Finally, We conducted this experiment based on the Caltech-101 database. By studying the experiment, the results have shown that this new retrieval method can decrease the interference of unstable interest points in the regions of non-interests and improve the ratios of accuracy and recall.
