Imagine trying to understand someone’s emotions when they can only express themselves through words. That’s the challenge researchers face when diagnosing Alzheimer’s disease (AD) based on language. But fear not, a new study proposes a solution! By developing a two-level attention mechanism, the researchers were able to detect deep semantic information and focus on important words and sentences in AD transcripts. And guess what? The results were extraordinary, with the method achieving an impressive accuracy of 91.6% on annotated public Pitt corpora. This not only validates the effectiveness of the model, but it also opens up new possibilities for diagnosing AD based on implicit sentiment in language. With further research and exploration, we could unlock even more insights into the emotional aspects of AD, helping to improve detection and treatment.

BackgroundAlzheimer’s disease (AD) is difficult to diagnose on the basis of language because of the implicit emotion of transcripts, which is defined as a supervised fuzzy implicit emotion classification at the document level. Recent neural network-based approaches have not paid attention to the implicit sentiments entailed in AD transcripts.MethodA two-level attention mechanism is proposed to detect deep semantic information toward words and sentences, which enables it to attend to more words and fewer sentences differentially when constructing document representation. Specifically, a document vector was built by progressively aggregating important words into sentence vectors and important sentences into document vectors.ResultsExperimental results showed that our method achieved the best accuracy of 91.6% on annotated public Pitt corpora, which validates its effectiveness in learning implicit sentiment representation for our model.ConclusionThe proposed model can qualitatively select informative words and sentences using attention layers, and this method also provides good inspiration for AD diagnosis based on implicit sentiment transcripts.
