A Review of Existing Conversational Recommendation Systems Subiya Zaidi, Sawan Rai, Kapil Juneja 2024 2nd International Conference on Disruptive Technologies Icdt 2024, 2024 ChatGPT, Alexa, Siri, Okay Google are an indispensable part of our lives today. These assistants are referred to as Digital Assistants and enable users to communicate their choices through natural language. The Digital Assistants ease the customer task of selecting items in various applications like movies, songs and so on. This process of making a choice through natural language conversations is known as a Conversational Recommender system (CoRS). CoRS is a dialogue-based model which aims to provide customer with accurate and quality recommendations. The interaction-oriented method gives the customer an edge over the traditional way of seeking recommendations. The traditional recommendation systems are static in nature and derive information through past history of the customer. A CoRS mitigates the challenges faced in the earlier methods of recommendation like cold start where in a new user is often recommended inaccurate choices. Other issues like data sparsity and lack of diversity due to not so updated content to choose from are common. CoRS is dynamic in nature, it works on delivering high end choices by interpreting the customer demands one dialogue at a time. This comprehensive survey aims to give an overview of the research in progress using conversation as a means to achieve better results for recommendation systems.
Advanced Hierarchical Topic Labeling for Short Text Paras Tiwari, Ashutosh Tripathi, Avaneesh Singh, Sawan Rai IEEE Access, 2023 Hierarchical Topic Modeling is the probabilistic approach for discovering latent topics distributed hierarchically among the documents. The distributed topics are represented with the respective topic terms. An unambiguous conclusion from the topic term distribution is a challenge for readers. The hierarchical topic labeling eases the challenge by facilitating an individual, appropriate label for each topic at every level. In this work, we propose a BERT-embedding inspired methodology for labeling hierarchical topics in short text corpora. The short texts have gained significant popularity on multiple platforms in diverse domains. The limited information available in the short text makes it difficult to deal with. In our work, we have used three diverse short text datasets that include both structured and unstructured instances. Such diversity ensures the broad application scope of this work. Considering the relevancy factor of the labels, the proposed methodology has been compared against both automatic and human annotators. Our proposed methodology outperformed the benchmark with an average score of 0.4185, 49.50, and 49.16 for cosine similarity, exact match, and partial match, respectively.
