In addition, we can also select multiple fields as targets, then the system will use time series of multiple topics to predict their future values.
But because a basic premise of faceted search is value "mutual exclusivity" [ 26], it prevents the assignment of multiple topics to a single question.
To automatically find associated questions for a given question and to assign multiple topics to questions, co-occurrences of CUIs were taken into account.
Another interesting thing is to look at co-occurrence of authors among multiple topics (for simplicity, we only consider two).
Furthermore, TM captures multiple meanings of words, but most importantly, it can identify multiple topics for each observed document.
Findings include: (1) 81% of two-query sessions included multiple topics, (2) 91.3% of three or more query sessions included multiple topics, (3) there are a broad variety of topics in multitasking search sessions, and (4) three or more query sessions sometimes contained frequent topic changes.
Topic models are based on the assumption that documents are typically composed of multiple topics.
Keyterm Clustering Based on Semantics In general, a document consists of multiple topics.
Our experiments in the subsequent section will highlight the importance of LTMs, which allow us to represent a turn as a mixture of multiple topics, towards classification, especially along the valence dimension.
