This research article develops an Arabic books' recommendation system, which is based on the content similarity that assists users to search for the right book and predict the appropriate and suitable books pertaining to their literary style. In fact, the system directs its users toward books, which can meet their needs from a large dataset of Information. Further, this system makes its predictions based on a set of data that is gathered from different books and converts it to vectors by using the TF-IDF system. After that, the recommendation algorithms such as the cosine similarity, the sequence matcher similarity, and the semantic similarity aggregate data to produce an efficient and effective recommendation. This approach is advantageous in recommending previously unrated books to users with unique interests. It is found to be proven from the obtained results that the results of the cosine similarity of the full content of books, the results of the sequence matcher similarity of Arabic titles of the books, and the results of the semantic similarity of English titles of the books are the best obtained results, and extremely close to the average of the result related to the human assigned/annotated similarity. Flask web application is developed with a simple interface to show the recommended Arabic books by using cosine similarity, sequence matcher similarity, and semantic similarity algorithms with all experiments that are conducted.

본 논문은 DPI (deep packet insepction)를 위한 CAM (content-addressable memory)과 병렬의 비트 분리(bit-split) 문자열 매처(matcher)를 이용한 2단의 문자열 매칭 엔진의 구조를 제안한다. 긴 타겟 패턴은 같은 길이의 서브 패턴으로 잘라지게 되고, 각 서브패턴은 1단의 CAM에 매핑된다. CAM으로부터의 매칭 인덱스의 시퀀스를 사용하여 2단에서 긴 패턴의 매칭 여부를 알 수 있다. CAM과 비트 분리 문자열 매처를 사용하여 이 기종의 메모리를 사용했을 경우에 메모리 요구량을 크게 줄일 수 있다.
