基于情境感知的上下文推荐系统的改进

Situation-Aware Approach to Improve Context-based Recommender System

Djallel Bouneffouf

摘要:

在本文中,我们介绍了一种新的情况下意识到的方法,以改善基于上下文的推荐系统。为了建立情境感知的用户简档,我们依赖于从检索情境发出的证据。检索情境是指用户与推荐系统交互时的社会时空背景。一个情境被表示为从给定社会群体、位置和时间信息的本体知识推断出的社会时空概念的组合。用户的兴趣从过去用户与推荐系统的交互中推断,所述推荐系统与所识别的情况有关。它们使用从领域本体发出的概念来表示。我们还提出了一种方法来动态地适应系统的用户的兴趣的演变。

英文摘要:

In this paper, we introduce a novel situation aware approach to improve a context based recommender system. To build situation aware user profiles, we rely on evidence issued from retrieval situations. A retrieval situation refers to the social spatio temporal context of the user when he interacts with the recommender system. A situation is represented as a combination of social spatio temporal concepts inferred from ontological knowledge given social group, location and time information. User's interests are inferred from past user's interaction with the recommender system related to the identified situations. They are represented using concepts issued from a domain ontology. We also propose a method to dynamically adapt the system to the user's interest's evolution.
