A topic detection model based on hierarchical clustering for Chinese microblog is proposed in this paper. In order to minimize the impact of noise, we optimize the feature selection and weight computation method and use a new scoring method to filter out those topic-unrelated tweets. We also give an improved topic detection algorithm which uses a new vector distance calculation method and cente...

There are many ways to communicate with people, the most representative of which is a conversation. A smooth conversation should not only be written in grammatically appropriate manner, but also deal subject conversation; this known as language ability. In past, ability has been evaluated by analysis/therapy experts. However, process time-consuming and costly. study, researchers developed Hally...

This paper discusses algorithms for topic selection queries, designed to query a database containing metadata about web information resources. The metadata database contains topics and relationships, called metalinks, about topics. Topics in the database contain associated importance scores. The topic selection operator TSelection selects, within time T, topics that satisfy a given selection fo...

We explore methods for content selection and address the issue of coherence in the context of the generation of multimedia artifacts. We use audio and video to present two case studies: generation of film tributes, and lecture-driven science talks. For content selection, we use centrality-based and diversity-based summarization, along with topic analysis. To establish coherence, we use the emot...

Due to the success of pre-trained language model (PLM), existing PLM-based summarization models show their powerful generative capability. However, these are trained on general-purpose datasets, leading generated summaries failing satisfy needs different readers. To generate with topics, many efforts have been made topic-focused summarization. works a summary only guided by prompt comprising to...

Numerous research studies suggest that at least one in five female college students is sexually assaulted while enrolled. However, many studies exploring sexual violence prevalence on campus use methodology permitting students to self-select into the study based on interest in the topic (i.e., students receive an email offering them the opportunity to participate in a study on sexual violence)....
