Peer to Peer Optimistic Collaborative Editing on XML-like trees

Collaborative editing consists in editing a common document shared by several independent sites. This may give rise to conficts when two different users perform simultaneous uncompatible operations. Centralized systems solve this problem by using locks that prevent some modifications to occur and leave the resolution of confict to users. On the contrary, peer to peer (P2P) editing doesn't allow locks and the optimistic approach uses a Integration Transformation IT that reconciliates the conficting operations and ensures convergence (all copies are identical on each site). Two properties TP1 and TP2, relating the set of allowed operations Op and the transformation IT, have been shown to ensure the correctness of the process. The choice of the set Op is crucial to define an integration operation that satisfies TP1 and TP2. Many existing algorithms don't satisfy these properties and are indeed incorrect i.e. convergence is not guaranteed. No algorithm enjoying both properties is known for strings and little work has been done for XML trees in a pure P2P framework (that doesn't use time-stamps for instance). We focus on editing unranked unordered labeled trees, so-called XML-like trees that are considered for instance in the Harmony pro ject. We show that no transformation satisfying TP1 and TP2 can exist for a first set of operations but we show that TP1 and TP2 hold for a richer set of operations. We show how to combine our approach with any convergent editing process on strings (not necessarily based on integration transformation) to get a convergent process

Research report : Collaborative Peer 2 Peer Edition: Avoiding Conflicts is Better than Solving Conflicts

Collaborative edition is achieved by distinct sites that work independently on (a copy of) a shared document. Conflicts may arise during this process and must be solved by the collaborative editor. In pure Peer to Peer collaborative editing, no centralization nor locks nor time-stamps are used which make conflict resolution difficult. We propose an algorithm which relies on the notion or semantics dependence and avoids the need of any integration transformation to solve conflicts. Furthermore, it doesn't use any history file recording operations performed since starting the edition process. We show how to define editing operations for semi-structured documents i.e. XML-like trees, that are enriched with informations derived for free from the editing process. Then we define the semantics dependence relation required by the algorithm and we present preliminary results obtained by a prototype implementation.Comment: 12 page

PEMBELAJARAN MENYUNTING TEKS EKSPLANASI KOMPLEKS KESEJARAHAN DENGAN MENGGUNAKAN TEKNIK PEER EDITING PADA SISWA KELAS XI IPA 1 SMAN 1 SOREANG TAHUN PELAJARAN 2015/2016

Menyunting adalah menyiapkan, menyeleksi dan menyesuaikan naskah orang lain dalam rangka perbaikan. Teks eksplanasi kompleks adalah teks yang menjelaskan fenomena alam, sosial, budaya atau sejarah. Teknik peer editing adalah teknik yang mengajari siswa cara mengidentifikasi fitur-fitur tulisan yang baik dan buruk dalam pekerjaan orang lain sehingga bisa mengembangkan keterampilan evaluasi kritis yang dapat mereka terapkan pada tulisan mereka sendiri. Rumusan masalah yang penulis ajukan adalah: 1) Mampukah penulis merencanakan, melaksanakan, dan mengevaluasi pembelajaran menyunting teks eksplanasi kompleks kesejarahan dengan teknik peer editing pada siswa kelas XI IPA 1 SMA Negeri 1 Soreang; 2) Mampukah siswa kelas XI IPA 1 SMA Negeri 1 Soreang menyunting teks eksplanasi kompleks berdasarkan struktur, ciri kebahasaan, dan kaidah penulisan dengan menggunakan teknik peer editing; 3) Efektifkah teknik peer editing digunakan dalam pembelajaran menyunting teks eksplanasi kesejarahan pada siswa kelas XI IPA 1 SMA Negeri 1 Soreang. Hipotesis yang penulis rumuskan yaitu: 1) Penulis mampu merencanakan, melaksanakan, dan mengevaluasi pembelajaran menyunting teks eksplanasi kompleks kesejarahan dengan teknik peer editing pada siswa kelas XI IPA 1 SMA Negeri 1 Soreang; 2) Siswa kelas XI IPA 1 SMA Negeri 1 Soreang mampu menyunting teks eksplanasi kompleks kesejarahan berdasarkan struktur, ciri kebahasaan, dan kaidah penulisan; 3)Teknik Peer Editing efektif digunakan dalam pembelajaran menyunting teks eksplanasi kompleks pada siswa kelas XI IPA 1 SMA Negeri 1 Soreang. Metode penelitian yang penulis gunakan adalah metode eksperimen semu. Adapun sampel penelitiannya sebagai berikut. 1. Penulis mampu merencanakan, melaksanakan, dan mengevaluasi pembelajaran menyunting teks eksplanasi kompleks kesejarahan dengan teknik peer editing pada siswa kelas XI IPA SMAN 1 Soreang. Hal ini terbukti dari hasil nilai perencanaan 3,97 dan pelaksanaan sebesar 3,76. 2. Siswa kelas XI IPA SMAN 1 Soreang mampu menyunting teks eksplanasi kompleks kesejarahan dengan menggunakan teknik peer editing. Hal ini terbukti dari nilai ratarata pretes yaitu 5,56, dan nilai rata-rata postes yaitu 7,93. Jadi ada peningkatan sebesar 9,44%. 3. Teknik peer editing efektif digunakan dalam pembelajaran menyunting teks eksplanasi kompleks kesejarahan pada siswa kelas XI IPA SMAN 1 Soreang. Hal ini terbukti dari hasil perhitungan statistik dengan hasil t hitung ≥ t tabel, yaitu 16,8 ≥ 2,06 pada tingkat kepercayaan 95% dan db sebesar 24. Dengan demikian, teknik peer editing cocok digunakan sebagai pembelajaran hal ini terlihat dengan adanya peningkatan hasil nilai yang diperoleh siswa Kata kunci : Pembelajaran, teks eksplanasi kompleks, kesejarahan, teknik peer editing

Data Consistency for P2P Collaborative Editing

http://portal.acm.org/Peer-to-peer (P2P) networks are very efficient for distributing content. We want to use this potential to allow not only distribution but collaborative editing of this content. Existing collaborative editing systems are centralised or depend on the number of sites. such systems cannot scale when deployed on P2P networks. In this paper, we propose a new model for building a collaborative editing system. This model is fully decentralised and does not depend on the number of sites

Peer-editing practice in the writing classrooms: Benefits and drawbacks

Small scale studies have shown that peer-editing is beneficial to students as it increases their awareness of the complex process of writing improves their knowledge of and skills in writing and helps them become more autonomous in learning. Teachers too may benefit from peer-editing as this practice discloses invaluable information on students’ writing weaknesses and strengths; and teachers’ teaching effectiveness. This is a small scale study conducted on fifteen first-year degree students majoring in Tourism to view the usefulness of peer-editing practice in enhancing their writing skills....1 PEER-EDITING PRACTICE IN THE WRITING CLASSROOM: BENEFITS AND DRAWBACKS Ann Rosnida Md. Deni Zainor Izat Zainal Small scale studies have shown that peer-editing is beneficial to students as it increases their awareness of the complex process of writing improves their knowledge of and skills in writing and helps them become more autonomous in learning. Teachers too may benefit from peer-editing as this practice discloses invaluable information on students’ writing weaknesses and strengths; and teachers’ teaching effectiveness. This is a small scale study conducted on fifteen first-year degree students majoring in Tourism to view the usefulness of peer-editing practice in enhancing their writing skills. Retrospective notes were taken to record students’ receptiveness and reaction towards peer editing practice; students’ writing samples and peer-editing questionnaires were analysed to view students’ revisions and comments; and an open-ended questionnaire was distributed to identify students’ perceptions of peer-editing practice in the writing classroom. Analysis of data gathered revealed that peer-editing practice benefitted both the teacher and most of her students as it exposed important information that could improve her teaching of writing and her students’ writing practices
