Abstract

Sistem temu kembali dokumen teks membutuhkan metode yang mampu mengembalikan sejumlah dokumen yang memiliki relevansi tinggi sesuai dengan permintaan pengguna. Salah satu tahapan penting dalam proses representasi teks adalah proses pembobotan. Penggunaan LCS dalam penyesuaian bobot Tf -Idf mempertimbangkan kemunculan urutan kata yang sama antara query dan teks di dalam dokumen. Adanya dokumen yang sangat panjang namun tidak relevan menyebabkan bobot yang dihasilkan tidak mampu merepresentasikan nilai relevansi dokumen. Penelitian ini mengusulkan penggunaan metode LCS yang memberikan bobot urutan kata dengan mempertimbangkan panjang dokumen terkait dengan rata-rata panjang dokumen dalam korpus. Metode ini mampu melakukan pengembalian dokumen teks secara efektif. Penambahan fitur urutan kata dengan normalisasi rasio panjang dokumen terhadap keseluruhan dokumen dalam korpus menghasilkan nilai presisi dan recall yang sama baiknya dengan metode sebelumnya.

Abstract

In service oriented computing, web services are the basic construct that aims to facilitate building of business application in a more flexible and interoperable manner for enterprise collaboration. One of the most promising advantages of web service technology is the possibility of creating added-value services by combining existing ones. A key step for composing and executing services lies in the selection of the individual services to use. Much attention has been devoted to appropriate selection of service functionalities, but also the non-functional properties of the services play a key role. A web service selection technique must take as much as possible the important influencing aspects into account to the selection processes in order to minimize the selection efforts. This paper evaluates several web service selection techniques published in literature with the focus on their contributions to web service selection. The evaluation results may be used as a basis for improving web service selection techniques that may simplify the selection tasks.

Abstract

Kekuatan ERP terletak dari banyaknya kebutuhan workflow yang disediakan. Perusahaan yangmenggunakan perangkat lunak ERP menginginkan investasi yang telah dikeluarkan mampu untukmendukung bisnis yang terus bertransformasi. Mempertimbangkan hal ini, maka kami mengusulkansebuah metode yang disebut tempat penyimpanan workflow (workflow repository). Workflow yangdisimpan dapat berbentuk workflow model dan dapat digunakan secara pribadi atau dibagikan kepadapublik. Hal ini tergantung pada pengembang workflow. Workflow yang disimpan dipetakanmenggunakan atribut yang mirip dengan OWL-s dan atribut kualitas workflow. Pengguna akhirmendapatkan workflow tersebut kembali dengan mempertimbangkan aspek dari perhitungankemiripan OWL-s, kualitas, konteks dan struktur. Untuk mendapatkan workflow kembali, workflowrepository menggunakan teknik prioritasisasi. Teknik prioritasisasi memiliki akurasi yang baik dancocok digunakan karena memberikan garansi hasil yang bebas dari workflow yang tidak dapatdieksekusi dari langkah pertama. Dengan metode ini, perusahaan yang telah berinvestasi padaperangkat lunak ERP dapat menggunakan akses workflow yang tersedia atau menjalankan workflowbersama dengan perusahaan lain. Percobaan untuk penelitian ini menggunakan ERP2011/13 dengandata tes skenario workflow model yang telah dikondisikan. Hasil yang didapatkan adalah tingkat temukembali (precision= rata-rata 0.5, recall=1) dan kemudahan akses dibanding mengelola workflowsecara konvensional. Kesimpulan, didapatkan bahwasannya metode prioritasisasi workflow memilikipresisi yang lebih tinggi.

Abstract

Information retrieval of text document requires a method that is able to restore a number of documents that have high relevance according to the user's request. One important step in the process is a text representation of the weighting process. The use of LCS in Tf-Idf weighting adjustments considers the appearance of the same order of words between the query and the text in the document. There is a very long document but irrelevant cause weight produced is not able to represent the value relevance of documents. This research proposes the use of LCS which gives weight to the word order by considering long documents related to the average length of documents in the corpus. This method is able to return a text document effectively. Additional features of word order by normalizing the ratio of the overall length of the document to the documents in the corpus generate values of precision and recall as well as the method of Tasi et al.

Abstract In service-oriented computing, web services are the basic foundation that aims to facilitate building of business application in a more flexible and interoperable manner for enterprise collaboration. One of the most promising advantages of web service technology is the possibility of creating added-value services by combining existing ones. A key step for composing and executing services lies in the selection of the individual service to use. Much attention has been devoted to appropriate selection of service functionalities, but also the non-functional properties of the services play a key role. A web service selection technique must take as much as possible the important influencing aspects into account to the selection process in order to minimize the selection efforts. This paper evaluates several web service selection techniques published in literature with the focus on their contributions to web service selection. The evaluation results can be used as a basis for improving web service selection techniques and then simplifying the selection tasks.
