Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Self-Schemas02:16

Self-Schemas

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
Cognitive Learning01:21

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
Nursing Clinical Information System01:27

Nursing Clinical Information System

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:
Heuristics01:21

Heuristics

Heuristics are problem-solving strategies that use mental shortcuts to simplify decision-making. Unlike algorithms, which must be followed precisely to achieve a correct result, heuristics offer a general problem-solving framework. They save time and energy but can sometimes lead to less rational decisions.
People often rely on heuristics when faced with an overload of information, limited time, low importance of the decision, limited information, or when a heuristic readily comes to mind. For...

Area of Science:

  • Information Science
  • Computer Science
  • Artificial Intelligence

Background:

  • Current smart library recommendation systems suffer from inaccurate user need perception and passive delivery patterns.
  • Existing methods like collaborative filtering and content-based filtering have limitations in user profiling and knowledge representation.
  • There's a need for proactive, context-aware recommendations that align with users' research rhythms and evolving interests.

Purpose of the Study:

  • To propose a smart library personalized resource proactive recommendation system.
  • To address limitations in user profiling, knowledge graph integration, and recommendation mechanisms.
  • To enhance resource discovery and user satisfaction through multi-dimensional user profiling and a disciplinary knowledge graph.

Main Methods:

  • Developed a multi-dimensional user profiling approach integrating borrowing records, retrieval logs, disciplinary backgrounds, and temporal patterns.
  • Constructed a library resource knowledge graph fusing metadata, disciplinary ontologies, and citation networks, utilizing graph attention networks (GAT) for embedding learning.
  • Implemented a context-aware proactive recommendation mechanism with interest drift detection and fused contextual signals for optimal push timing.

Main Results:

  • Achieved significant improvements in Recall@10 (4.87%) and NDCG@10 (5.23%) over baseline methods.
  • Demonstrated a proactive recommendation push acceptance rate of 38.9%, substantially outperforming random push.
  • Ablation studies confirmed the effectiveness of each module, with the knowledge graph module showing the most significant contribution.

Conclusions:

  • The proposed system effectively addresses the limitations of existing library recommendation services.
  • Integrating multi-dimensional user profiles and a disciplinary knowledge graph enhances recommendation accuracy and relevance.
  • Context-aware proactive recommendations significantly improve user engagement and resource discovery in smart libraries.
