The Plagiarism Problem in Academic Contexts

The practice of plagiarism often occurs in the academic context, such as in tasks, thesis, or scientific work. Many individuals are involved in this fraud by copying some or all of the work of others from journals or websites without making changes to the structure of words (copy-paste) and without including sources. This can lead to a loss of credibility and trust in academic institutions, as well as undermine the integrity of research and scholarship. To deal with this problem, experts have developed various algorithms that function to detect the similarity of documents.

Stemming Arifin-Setiono Method: A Key to Simplifying Document Comparison

Stemming Arifin-Setiono aims to find the basic words of each word in the document. This process is important because it can reduce the number of characters that must be processed in the document and can also simplify the sentence patterns to be compared. By using stemming, long and complex original documents can be narrowed into a simpler form, making it easier to identify similarity. This method is particularly useful in natural language processing, where the goal is to extract meaningful information from large amounts of text data.

How Stemming Arifin-Setiono Works

The stemming process involves removing suffixes from words to obtain their base form. For example, the word "running" would be reduced to "run". This process is repeated for all words in the document, resulting in a simplified representation of the text. The resulting stem words can then be compared to identify similarities between documents.

Boyer-Moore Algorithm: A Powerful Tool for String Matching

After the document text is processed through the stemming process, the next step is to compare the text using a Boyer-Moore algorithm. This algorithm is known to be effective for string search because of its ability to identify the same sentences in the two documents compared. With this approach, we can quickly determine whether there is a significant similarity between two texts. The Boyer-Moore algorithm works by precomputing a table of possible matches between the search string and the text, allowing for efficient searching and comparison.

How Boyer-Moore Algorithm Works

The Boyer-Moore algorithm involves two main steps: the precomputation step and the search step. In the precomputation step, a table of possible matches is created by comparing the search string with the text. In the search step, the algorithm uses the precomputed table to efficiently search for matches between the search string and the text.

Similarity Calculation: Measuring the Degree of Similarity

This method will produce a similar value between the two documents in the form of a percentage. This process is carried out by calculating the similarity of sentences using Dice Coefficient Similarity, which is one way to evaluate how similar two sets of data. In addition, the system can also display the number of sentences of each document and identify the same number of sentences between the two. With these steps, we can get a clear picture of the level of plagiarism in the document under study.

Dice Coefficient Similarity

The Dice Coefficient Similarity is a measure of similarity between two sets of data. It is calculated by dividing the number of common elements between the two sets by the total number of elements in both sets. This measure is useful in identifying the degree of similarity between two documents.

Benefits and Implications of Using Arifin-Setiono Stemming Method and Boyer-Moore Algorithm

The use of a combination of Arifin-Setiono Stemming Method and Boyer-Moore Algorithm in detecting similar documents offers effective solutions to fight plagiarism. In this way, educators and academic institutions can more easily identify the actions of plagiarism, which in turn can increase integrity in the delivery of scientific papers. In addition, this study also opened the way for the development of a more accurate and efficient plagiarism detection device in the future.

Advantages of Using Arifin-Setiono Stemming Method and Boyer-Moore Algorithm

The use of Arifin-Setiono Stemming Method and Boyer-Moore Algorithm offers several advantages, including:

Improved accuracy: The combination of stemming and string matching algorithms provides a more accurate measure of similarity between documents.
Increased efficiency: The use of precomputed tables and efficient searching algorithms reduces the time required to compare documents.
Enhanced plagiarism detection: The ability to identify similar sentences and calculate the degree of similarity between documents makes it easier to detect plagiarism.

Conclusion

Detecting plagiarism using these two methods not only provides added value in processing document data, but also encourages more ethical and responsible academic culture. With a better understanding of this technique and algorithm, we can take proactive steps to fight plagiarism in various academic and professional contexts. By using a combination of Arifin-Setiono Stemming Method and Boyer-Moore Algorithm, educators and academic institutions can increase integrity in the delivery of scientific papers and promote a culture of originality and creativity.
