With the development of over-the-top (OTT) services, the demand for content is increasing, and you can easily and conveniently acquire various content in the online environment. As a result, copyrighted content can be easily copied and distributed, resulting in serious copyright infringement. Some special forms of online service providers (OSP) use filtering-based technologies to protect copyrights, but illegal uploaders use methods that bypass traditional filters. Uploading with a title that bypasses the filter cannot use a similar search method to detect illegal content. In this paper, we propose a technique for profiling the Heavy Uploader by normalizing the bypassed content title and efficiently detecting illegal content. First, the word is extracted from the normalized title and converted into a bit-array to detect illegal works. This Bloom Filter method has a characteristic that there are false positives but no false negatives. The false positive rate has a trade-off relationship with processing performance. As the false positive rate increases, the processing performance increases, and when the false positive rate decreases, the processing performance increases. We increased the detection rate by directly comparing the word to the result of increasing the false positive rate of the Bloom Filter. The processing time was also as fast as when the false positive rate was increased. Afterwards, we create a function that includes information about overall piracy and identify clustering-based heavy uploaders. Analyze the behavior of heavy uploaders to find the first uploader and detect the source site.

This excerpt delineates a quantitative measure of relationship between a research title and its respective abstract extracted from different journal articles documented through a Korean Citation Index (KCI) database published through various journals. In this paper, we propose a machine learning-based similarity metric that does not assume normality on dataset, realizes the imbalanced dataset problem, and zero-variance problem that affects most of the rule-based algorithms. The advantage of using this algorithm is that, it eliminates the limitations experienced by Pearson correlation coefficient (r) and additionally, it solves imbalanced dataset problem. A total of 107 journal articles collected from the database were used to develop a corpus with authors, year of publication, title, and an abstract per each. Based on the experimental results, the proposed algorithm achieved high correlation coefficient values compared to others which are cosine similarity, euclidean, and pearson correlation coefficients by scoring a maximum correlation of 1, whereas others had obtained non-a-number value to some experiments. With these results, we found that an effective title must have high correlation coefficient with the respective abstract.

This study was to suggest the new rules for revision of KCR4 by comparing between ISBD consolidated edition and KCR4. The study methods was to compare the rules in each element after mapping the description elements in each area of ISBD and KCR4. Resultingly, first, content forms and media types must be included for describing resource types. Second, it is needed for rules about the common title and the dependent title. Third, it is needed for rules about "parallel" such as parallel title, parallel other title information, parallel statement of responsibility relating to title, parallel edition statement, parallel statement of responsibility relating to edition, parallel numbering system, parallel place of publication, production and distribution, et. al. Fourth, the rules about material or type of resource specific area must be regulated in terms of the contents of the resource. Fifth, the home country principle must be not applied in describing the place of publication, production and distribution for the consistency. Sixth, it is needed to regulate the extent, other physical details, dimensions, and accompanying material statement for all materials instead of the material description according to material types. Seventh, rule number of notes must be agreed to number of main rules. Eighth, it is needed for detailed rules about resource identifier. This study might be contributed to revise the KCR4.

This study comparatively analyzed the instrumentation and the voicing structure, which were shown in the film music titled "Star Wars-Main Title" by John Williams(1932~), with analytical technique that the writer mapped out, and aimed to discover the progression principle in orchestration based on the results. Also, it applied a functional part-division method that was classified and distributed into 3 functional parts according to auditory cognitive level as for each of functional elements such as the musical element. And, it made it pattern for the vertical structure and the voicing structure in musical instruments, which were distributed to each functional part based on this, and comparatively analyzed the standard point in a change which were shown according to progression of music, namely, the operating technique. As for the results of this study, first, each theme has specific instrumentation pattern. Unity was emphasized by consistently organizing those things in exposition, reprise, and recapitulation of each theme. To reinforce diversity, an attempt was made such as adding and reducing auxiliary instruments in the middle part and the rear part. Second, even in a change of instrumentation pattern by passage in accordance with a change in theme amid each part, the same instrumental group was organized in the middle part, thereby having maintained unity. Third, to strengthen diversity by clause, which is forming each theme, a continuous change in voicing pattern was created by adding or omitting a part. Fourth, the voicing concentration was maintained the structure of "thinness-thickness" in the whole musical piece. However, in part 2 that is repeated theme 3, diversity was pursued with a unique change of "thickness-thickness." Fifth, in part 4 that is indicated theme 4, the other diversity was intensified with the inverted range in the front part and the middle part. Accordingly, based on the conclusions that were indicated in this work, it is desired to be conducive to understanding the horizontal consideration and the progression principle of orchestration.
