A web 3.0 cultural tourism marketing platform based on improved transformer recommendation model


Abstract

The digital transformation of cultural tourism requires intelligent algorithms capable of modeling heterogeneous and abstract user demands. This paper proposes a Web 3.0-based digital marketing framework for cultural tourism that integrates abstract element fusion analysis with an improved Transformer recommendation model. First, a hybrid architecture is designed, where a convolutional neural network (CNN) is employed to extract fused representations from abstract features (user preferences, intentions, expectations) and concrete features of cultural tourism resources. These fused representations are then processed by a Transformer with an enhanced self-attention mechanism incorporating relative positional encoding, which strengthens the correlation modeling between users and resource entities. Furthermore, a knowledge-graph-based relation scoring module is introduced to refine multi-entity recommendations. Experimental evaluations on the Tourism Statistics Database demonstrate that the proposed model achieves superior accuracy (90.23%), recall (90.67%), and F-measure (91.98%) compared with state-of-the-art baselines. Ablation studies verify the effectiveness of both the abstract element fusion module and the improved self-attention mechanism. Application-level simulations confirm that the system can provide real-time, precise, and personalized recommendations, thereby offering a scalable and robust solution for digital marketing in cultural tourism.

Notes for potential reviewers

  • Volunteering is not a guarantee that you will be asked to review. There are many reasons: reviewers must be qualified, there should be no conflicts of interest, a minimum of two reviewers have already accepted an invitation, etc.
  • This is NOT OPEN peer review. The review is single-blind, and all recommendations are sent privately to the Academic Editor handling the manuscript. All reviews are published and reviewers can choose to sign their reviews.
  • What happens after volunteering? It may be a few days before you receive an invitation to review with further instructions. You will need to accept the invitation to then become an official referee for the manuscript. If you do not receive an invitation it is for one of many possible reasons as noted above.

  • PeerJ Computer Science does not judge submissions based on subjective measures such as novelty, impact or degree of advance. Effectively, reviewers are asked to comment on whether or not the submission is scientifically and technically sound and therefore deserves to join the scientific literature. Our Peer Review criteria can be found on the "Editorial Criteria" page - reviewers are specifically asked to comment on 3 broad areas: "Basic Reporting", "Experimental Design" and "Validity of the Findings".
  • Reviewers are expected to comment in a timely, professional, and constructive manner.
  • Until the article is published, reviewers must regard all information relating to the submission as strictly confidential.
  • When submitting a review, reviewers are given the option to "sign" their review (i.e. to associate their name with their comments). Otherwise, all review comments remain anonymous.
  • All reviews of published articles are published. This includes manuscript files, peer review comments, author rebuttals and revised materials.
  • Each time a decision is made by the Academic Editor, each reviewer will receive a copy of the Decision Letter (which will include the comments of all reviewers).
