Have you read the white paper guys? I think most concerns were address in LINA white paper.
Here are some lines quoted from the white paper.
1. Value of online product review
With the explosion of the Internet, product reviews have become an important factor in building brand image and business reputation. A negative review can seriously affect the reputation of the business. This has even created an industry known as “reputation management” with the primary functions of helping companies “concealing” bad reviews [1]. However, from the users’ perspective, this is not a good thing because it hinders them in accessing transparent and trustful reviews.
In the review industry, reviews of the experts play a decisive role. Expert reviews are usually written by reputable experts who have tried and tested products and services to find the best value for money. However, it is usually difficult for ordinary users to access these experts, while that should really be the main communication channel in the review industry.
2. Aspects of current review industry
2.1 Reliability of reviews and scores
While the importance of the review industry is undeniable, the most important part - the credibility of the score - is in question.
This happens because, in theory, the reviewers should be responsible for making the objective, unbiased and the most accurate reviews possible, but in reality there is currently no evaluation mechanism for the reviewers themselves, so there is no clear connection between the benefits and the quality of the reviews of experts. When the experts do not have the motivation and responsibility to do their job, it is predictable that the quality of expert review would be reduced or influenced by other factors.
Besides, the lack of a transparent communication mechanism between the websites’ offering review system and end users also creates a loophole that allows product or service providers to easily deal with the current rating system manager and thereby change review scores in their favor.
Consequentially, end users lose their trust in review results, while review experts do not have motivation to work. Therefore, manufacturers could not receive honest feedback to improve their products. It is a lose-lose-lose situation.
2.2 Difficulties in finding and comparing evaluation results
At present, there are many rating systems in different industries. These systems are quite dispersed resulting in difficulty for users to search reviews.
2.3 Lack of standard criteria for each subject
Therefore, it is necessary to build standard criteria for each subject in order to help business get the most accurate feedback from customer. Thanks to the assistance of a network of experts in many industries, Lina.review has introduced a set of criteria applied to more than 20 fields ranging from technological products, medical services or hotels, to movies and books. In addition to being able to get the most accurate feedback from users about the selected criteria, Lina.review has introduced the Lina Rating app (available on Google Play) so that users can “vote” for the criteria to be reviewed, currently for 6 subjects:
• Medical Service, Hospital
• Hotels
• Movie
• Restaurant
• Crypto Currency
• Smart Phone
The obtained results are fairly interesting, for example, for restaurants, the number of people voting for “Cleanliness” is greater than the number of people voted for “Food Quality”, and the number of people voting for “Ambience” and “Food safety” is nearly equal to “Food Quality”. This partly indicates that existing restaurant review criteria need to be updated.
3 Introducing Lina.review - community-driven review platform powered by Blockchain Technology
