Sentence examples for semantic topic from inspiring English sources

In this way, semantic topics generate tags or classes for images with each defining a prior distribution in visual topic space.

We develop a topic-driven initialization scheme, so that each learned relation type can be interpreted as a representative of semantic topics of the objects.

'IXN' and 'TOPIC' mean semantic and topic features, respectively.

The five analytical techniques are cosine similarity using term frequency-inverse document frequency vectors (tf-idf cosine), latent semantic analysis (LSA), topic modeling, and two Poisson-based language models – BM25 and PMRA (PubMed Related Articles).
