Intelligent recommendation technology has been playing an increasingly important role in various industry applications such as e-commerce product promotion and Internet advertisement display. Besides ...user feedbacks (e.g., numerical ratings) on items as usually exploited by some typical recommendation algorithms, there are often some additional data such as users׳ social circles and other behaviors. Such auxiliary data are usually related to user preferences on items behind numerical ratings. Collaborative recommendation with auxiliary data (CRAD) aims to leverage such additional information so as to improve personalized services. It has received much attention from both researchers and practitioners.
Transfer learning (TL) is proposed to extract and transfer knowledge from some auxiliary data in order to assist the learning task on the target data. In this survey, we consider the CRAD problem from a transfer learning view, especially on how to enable knowledge transfer from some auxiliary data, and discuss the representative transfer learning techniques. Firstly, we give a formal definition of transfer learning for CRAD (TL-CRAD). Secondly, we extend the existing categorization of TL techniques with three knowledge transfer strategies. Thirdly, we propose a novel and generic knowledge transfer framework for TL-CRAD. Fourthly, we describe some representative works of each specific knowledge transfer strategy in detail, which are expected to inspire further works. Finally, we conclude the survey with some summarized discussions and several future directions.

Tujuan Penelitian untuk mengetahui bagaimana strategi-strategi pemerintah Kota Malang dalam penertiban pemasangan banner dan reklame ilegal disepanjang Jalan Sukarno Hatta sampai Jalan Tlogomas dan untuk mengetahui bagaimana optimalisasi pemerintah Kota Malang dalam pengawasan dan penertiban terhadap pemasangan banner dan reklame ilegal disepanjang Jalan Sukarno Hatta sampai Jalan Tlogomas. Dalam penelitian ini, peneliti menggunakan jenis penelitian deskriptif – kualitatif. Hybert Hyman dalam Koentjaraningrat (1991:29) mengartikan jenis penelitian yang bersifat deskriptif adalah penelitian yang bersifat deskriptif adalah penelitian yang mempunyai tujuan untuk menggambarkan secara tepat tentang sifat-sifat suatu individu, keadaan, gejala, atau kelompok-kelompok tertentu atau untuk menentukan frekuensi adanya hubungan tertentu antara suatu gejala atau frekuensi adanya hubungan tertentu antara suatu gejala dengan gejala lain di masyarakat. Sedangkan metode penelitian kualitatif sesuai dengan yang dikemukakan oleh Bogdan dan Taylor dalam Moleong (2002:3) bahwa metode kualitatif didefinisikan sebagai prosedur penelitian yang menghasilkan data deskriptif berupa kata-kata tertulis atau lisan dari orang-orang dan perilaku yang dapat diamati. Pemasangan papan reklame, sebetulnya sudah ada mekanismenya, seperti papan reklame harus dipasang pada tempat yang memang tidak mengganggu kepentingan publik seperti di trotoar. Bila ada pemasangan reklame tidak pada tempatnya, kewajiban petugas Tramtib di kecamatan dan kelurahan untuk melarangnya dan mengarahkan pemasangan reklame sesuai ketentuan yang berlaku. Apabila pemasangan papan reklame tidak pada tempatnya, berdampak besar terhadap terganggunya keamanan dan kenyaman publik serta keindahan daerah. Bukan saja dilarang pasang di trotoar, konstruksi papan reklame juga harus melihat segi keamanan dan kenyamanan, jangan-jangan suatu ketika tiba-tiba reklamenya roboh hingga menimbulkan korban bagi orang lain. Maka diperlukan penegakan hukum agar tercapai ketertiban dan kepatuhan terhadap peraturan dalam perizinan reklame.Selain untuk pembinaan, pengaturan, pengendalian dan pengawasan serta penegakan hukum dan dampak negatif dari pemberian izin dalam rangka melindungi kepentingan umum dan menjaga kelestarian lingkungan, maka perlu dilakukan pengaturan tentang Retribusi Izin Pemasangan Reklame.Bagi Pemerintah, dalam hal ini Pemerintah Daerah, reklame merupakan salah sumber APBD, dimana pelaku usaha yang berkepentingan terhadap pemasangan iklan tersebut membayar pajak dalam jumlah tertentu untuk pemasangan reklame dalam durasi tertentu di wilayah-wilayah strategis Kabupaten/Kotamadya.
In the last 3 years, several new (free) sources for academic publication and citation data have joined the now well-established Google Scholar, complementing the two traditional commercial data ...sources: Scopus and the Web of Science. The most important of these new data sources are Microsoft Academic (2016), Crossref (2017) and Dimensions (2018). Whereas Microsoft Academic has received some attention from the bibliometric community, there are as yet very few studies that have investigated the coverage of Crossref or Dimensions. To address this gap, this brief letter assesses Crossref and Dimensions coverage in comparison to Google Scholar, Microsoft Academic, Scopus and the Web of Science through a detailed investigation of the full publication and citation record of a single academic, as well as six top journals in Business & Economics. Overall, this first small-scale study suggests that, when compared to Scopus and the Web of Science, Crossref and Dimensions have a similar or better coverage for both publications and citations, but a substantively lower coverage than Google Scholar and Microsoft Academic. If our findings can be confirmed by larger-scale studies, Crossref and Dimensions might serve as good alternatives to Scopus and the Web of Science for both literature reviews and citation analysis. However, Google Scholar and Microsoft Academic maintain their position as the most comprehensive free sources for publication and citation data.
Unlike advertising in traditional media, a mobile platform's in‐app advertising market exhibits two unique features—split structure of the mobile platform with a platform owner and an app developer ...jointly provisioning in‐app advertising, and agency pricing for app sales. We develop a two‐sided market model to analyze the role of these two unique features in determining the platform owner's optimal advertising revenue‐sharing contract. Our results reveal an interesting N‐shaped dynamic regarding the platform owner's optimal choice of her ad revenue share with respect to the overall advertisers’ valuation of in‐app ads. We identify a between‐agent subsidization strategy for the platform owner, where she finds it optimal to subsidize the developer via the advertising channel, leading to greater profits for both of them. We find that the advertising revenue‐sharing contract under agency pricing for app sales leads to a higher app price than would be offered by the integrated platform found in traditional advertising. However, the ad price is coordinated under the platform owner's optimal choice of ad revenue share when she obtains revenue from both the advertising and app sales channels, leading to an alignment of her interest with the app developer's on ad level.
