Abstract
Purpose
The explosion of data due to the sophistication of information and communication technology makes it simple for prospective tourists to learn about previous hotel guests' experiences. They prioritize the rating score when selecting a hotel. However, rating scores are less reliable for suggesting a personalized preference for each aspect, especially when they are in a limited number. This study aims to recommend ratings and personalized preference hotels using cross-domain and aspect-based features.
Design/methodology/approach
We propose an aspect-based cross-domain personalized recommendation (AsCDPR), a novel framework for rating prediction and personalized customer preference recommendations. We incorporate a cross-domain personalized approach and aspect-based features of items from the review text. We extracted aspect-based feature vectors from two domains using bidirectional long short-term memory and then mapped them by a multilayer perceptron (MLP). The cross-domain recommendation module trains MLP to analyze sentiment and predict item ratings and the polarities of the aspect based on user preferences.
Findings
Expanded by its synonyms, aspect-based features significantly improve the performance of sentiment analysis on accuracy and the F1-score matrix. With relatively low mean absolute error and root mean square error values, AsCDPR outperforms matrix factorization, collaborative matrix factorization, EMCDPR and Personalized transfer of user preferences for cross-domain recommendation. These values are 1.3657 and 1.6682, respectively.
Research limitation/implications
This study assists users in recommending hotels based on their priority preferences. Users do not need to read other people's reviews to capture the key aspects of items. This model could enhance system reliability in the hospitality industry by providing personalized recommendations.
Originality/value
This study introduces a new approach that embeds aspect-based features of items in a cross-domain personalized recommendation. AsCDPR predicts ratings and provides recommendations based on priority aspects of each user's preferences.

Abstract
Purpose
This paper aims to study the Integrated Criminal Justice System; the law enforcement carried out by the Indonesian National Police is expected to be able to realize legal values, namely, legal justice, expediency and certainty.
Design/methodology/approach
This research can broadly be grouped into the realm of the socio-legal research approach. The domain of law enforcement in corruption cases is related to the preliminary investigation and full investigation process. The research location chosen is at Indonesian National Police Headquarter (Mabes Polri) and Greater Jakarta Metropolitan Regional Police. The main data sources are stakeholders who are related and have the authority as preliminary phase investigators and full phase investigators. The next informants are determined by snowball technique, which consists of several informants as follows: Director of Special Criminal Investigation Directorate of Greater Jakarta Metropolitan Regional Police, head of Corruption Crime Sub-Directorate of Greater Jakarta Metropolitan Regional Police, investigators of Corruption Crime Sub-Directorate of Special Criminal Investigation Directorate of Greater Jakarta Metropolitan Regional Police, members of Commission III of the Indonesian House of Representatives (DPR), constitutional law experts and police experts. The data in this research are obtained through observation activities, visual interviews, document interpretation (text) and material and personal experience.
Findings
The corruption cases handled by the Indonesian National Police have mostly come from information reports from the public. Based on the information report from the community, the preliminary investigation phase is carried out by the preliminary phase investigator of the Indonesian National Police in the field. In addition, a preliminary investigation and full investigation is carried out due to the results of an audit from the BPK or BPKP. Preliminary investigation and full investigation begin after it is alleged that a criminal act of corruption had occurred based on the report, complaints and information received by the preliminary phase investigator or full phase investigator from the community. In conducting the preliminary investigation and full investigation of corruption cases, based on the results of the research conducted, it is also found that the Indonesian National Police’s preliminary phase investigator and full phase investigator experience several obstacles, besides supporting factors that support the success of a preliminary investigation and full investigation.
Originality/value
This research is a case study in which no previous studies have used the same method in Greater Jakarta Metropolitan Regional Police (Polda Metro Jaya). This paper is the result of the researcher’s research on what is described above, guided by the constructivism paradigm, the researcher applies the paradigmatic analysis to understand how the preliminary investigation and full investigation on corruption crimes by Greater Jakarta Metropolitan Regional Police act as part of an integrated criminal justice system. Through the paradigmatic analysis, the researcher then reveals how while upholding the law, the Indonesian National Police actually sought to realize legal justice, expediency and certainty.

Abstract
Purpose
The purpose of this paper is to address two questions: first, what contracts, instruments and accounting activities constitute Australia’s offshore asylum seeker processing policy in practice? Second, how are notions of legitimacy and accountability mediated through the network constituted by this policy?
Design/methodology/approach
The paper is located in the critical interpretivist approach to accounting research. It is based on an exhaustive documentary analysis. Policy documents, contract documents, records of parliamentary inquiries (Hansard) and legislation were analysed drawing on a network policy perspective.
Findings
The paper finds that the Australian Government has sought to escape its accountability obligations by employing a range of approaches. The first of these approaches is the construction of a network involving foreign states, private corporations and non-government organizations. The second is through a watered down accountability regime and refusal to be accountable for the day-to-day life of asylum seekers in offshore processing centres through a play with the meaning of “effective control”. Yet while the policy network seems designed to create accountability gaps, the requirement within the network to remain financially accountable undermines the governments claims not to be responsible for the conditions in the detention camps.
Research limitations/implications
The paper focuses largely on the period starting from when Kevin Rudd became Prime Minister to the death in Papua New Guinea of asylum seeker Reza Barati on 17 February 2014. Earlier periods are beyond the scope of this paper.
Practical implications
The paper will result in the identification of deficiencies inhuman rights accountability for extra-territorialized and privatised immigration detention and may contribute towards the formulation of effective policy recommendations to overcome such deficiencies. The paper also provides empirical data on, and academic understanding of, immigration detention outsourcing and offshoring.
Social implications
The paper will inform debate regarding treatment of unauthorized maritime arrivals and asylum seekers generally.
Originality/value
The paper provides the first detailed and full understanding of the way Australia’s offshore asylum seeker processing policy is practiced. The paper also provides an empirical analysis of the way national policy and its associated accountability mechanisms emerge in response to the competing legitimacy claims of the international community and national electorate.
