Scholarly search engines, reference management tools, and academic social networks enable modern researchers to organize their scientific libraries. Moreover, they often provide recommendations for scientific publications that might be of interest to researchers. Because of the exponentially increasing volume of publications, effective citation recommendation is of great importance to researchers, as it reduces the time and effort spent on retrieving, understanding, and selecting research papers. In this context, we address the problem of citation recommendation, i.e., the task of recommending citations for a new paper. Current research investigates this task in different settings, including cases where rich user metadata is available (e.g., user profile, publications, citations). This work focus on a setting where the user provides only the abstract of a new paper as input. Our proposed approach is to expand the semantic features of the given abstract using knowledge graphs - and, combine them with other features (e.g., indegree, recency) to fit a learning to rank model. This model is used to generate the citation recommendations. By evaluating on real data, we show that the expanded semantic features lead to improving the quality of the recommendations measured by nDCG@10.

Title: sequential recommendation with latent relations based on large language model.
Abstract: Sequential recommender systems predict items that may interest users by modeling their preferences based on historical interactions. Traditional sequential recommendation methods rely on capturing implicit collaborative filtering signals among items. Recent relation-aware sequential recommendation models have achieved promising performance by explicitly incorporating item relations into the modeling of user historical sequences, where most relations are extracted from knowledge graphs. However, existing methods rely on manually predefined relations and suffer the sparsity issue, limiting the generalization ability in diverse scenarios with varied item relations. In this paper, we propose a novel relation-aware sequential recommendation framework with Latent Relation Discovery (LRD). Different from previous relation-aware models that rely on predefined rules, we propose to leverage the Large Language Model (LLM) to provide new types of relations and connections between items. The motivation is that LLM contains abundant world knowledge, which can be adopted to mine latent relations of items for recommendation. Specifically, inspired by that humans can describe relations between items using natural language, LRD harnesses the LLM that has demonstrated human-like knowledge to obtain language knowledge representations of items. These representations are fed into a latent relation discovery module based on the discrete state variational autoencoder (DVAE). Then the self-supervised relation discovery tasks and recommendation tasks are jointly optimized. Experimental results on multiple public datasets demonstrate our proposed latent relations discovery method can be incorporated with existing relation-aware sequential recommendation models and significantly improve the performance. Further analysis experiments indicate the effectiveness and reliability of the discovered latent relations.

In the face of a growing volume of patents, patent examiners grapple with prolonged examination cycles, prompting the need for more effective citation recommendations. To address this, we introduce the patent knowledge graph embedded in Bert (PK-Bert) model. This innovation combines a patent knowledge graph with semantic information in an advanced Transformer framework, outperforming conventional common-sense knowledge graph embedding. PK-Bert exhibits substantial improvements, boosting the recall of accurate citation recommendations by 2.15% over the benchmark model Bert and 1.25% over K-Bert with CnDBpedia. Ablation experiments highlight the significance of knowledge graph elements, with the inventor proving most influential, followed by the IPC number and assignee. At the same time, publication time and title information have a minor impact. Moreover, PK-Bert excels when trained with earlier data and evaluated for patents issued post-November 2023. Our study not only advances patent examiner recommendations but also presents an efficient integration method for knowledge graph-enhanced semantic patent characterization.

Here, we briefly review research KGs and approaches for citation recommendation. 2.1 Research Knowledge Graphs. Various KGs interlink research papers through metadata (e.g. authors, venues) and citations [13, 22], or through research artefacts (e.g. datasets) [1, 23].Other initiatives organise scientific knowledge in a structured manner with community effort, such as Gene Ontology [], WikiData ...

In this paper, we propose to exploit an additional source of information, namely research knowledge graphs (KGs) that interlink research papers based on mentioned scientific concepts. Our experimental results demonstrate that the combination of information from research KGs with existing state-of-the-art approaches is beneficial.
The overall knowledge graph and multi-task learning-based model for citation recommendation (KMCR) is shown in Fig. 1. The model is composed of three parts: a citation recommendation task module, a knowledge graph link prediction task module, and a feature sharing module. The left side is the citation recommendation task module.

In this context, we address the problem of citation recommendation, i.e., the task of recommending citations for a new paper. Current research investigates this task in different settings, including cases where rich user metadata is available (e.g., user profile, publications, citations).
This work focus on a setting where the user provides only the abstract of a new paper as input. Our proposed approach is to expand the semantic features of the given abstract using knowledge graphs - and, combine them with other features (e.g., indegree, recency) to fit a learning to rank model. This model is used to generate the citation ...
Therefore, this paper proposes a Content-based and knowledge Graph-based Paper Recommendation method (CGPRec), which uses a two-layer self-attention block to obtain global features of texts for more complete explicit user preferences, and proposes an improved graph convolutional network for modeling high-order associations on the knowledge ...
This work focuses on a setting where the user provides only the abstract of a new paper as input, and proposes a model to expand the semantic features of the given abstract using knowledge graphs and combine them with other features to fit a learning to rank model. Scholarly search engines, reference management tools, and academic social networks enable modern researchers to organize their ...
Citation recommendation for research papers is a valuable task that can help researchers improve the quality of their work by suggesting relevant related work. Current approaches for this task rely primarily on the text of the papers and the citation network. In this paper, we propose to exploit an additional source of information, namely research knowledge graphs (KG) that interlink research ...
Recommending helpful and interesting scholarly papers for researchers from a large number of scholarly papers is the main way to improve research efficiency. Traditional collaborative filtering or content-based recommendation methods do not have a better-fused knowledge graph and have method bottlenecks such as cold start and poor interpretation. Based on the knowledge-aware path recurrent ...
In the academic field, Ayala-Gomez et al. proposed to use knowledge graph to extend the semantic features of a given abstract and combine them with other features such as indegree and recency to ...
A Context-Aware Citation Recommendation Model with BERT and Graph Convolutional Networks. TeamLab/bert-gcn-for-paper-citation • • 15 Mar 2019. Many researchers have utilized the text data called the context sentence, which surrounds the citation tag, and the metadata of the target paper to find the appropriate cited research. 1.
To better use the abundant attributes and interaction information, the knowledge graph is introduced to recommendation system recently. We construct a multi-task learning-based model for citation ...
Automatic recommendation of citations has been a focal point of research in scholarly digital libraries. Many graph-based citation recommendation algorithms have been proposed; however, most of them utilize local citation behavior from the citation network that results in recommending papers in the same proximity as the query article. In this paper, we propose to capture the global citation ...
View a PDF of the paper titled Sequential Recommendation with Latent Relations based on Large Language Model, by Shenghao Yang and 6 other authors ... where most relations are extracted from knowledge graphs. However, existing methods rely on manually predefined relations and suffer the sparsity issue, limiting the generalization ability in ...
Graph Convolutional Neural Networks (GCNs) possess strong capabilities for processing graph data in non-grid domains. They can capture the topological logical structure and node features in graphs and integrate them into nodes' final representations. GCNs have been extensively studied in various fields, such as recommendation systems, social networks, and protein molecular structures. With the ...
