Based on introduction to the task of opinion mining and its related work, the paper puts forward the framework of opinion mining in Chinese with semantic analysis, meanwhile some key techniques in the framework are studies. The paper also gives more details about the tasks of opinion mining in...
We derive this representation with the aid of a thesaurus and latent semantic analysis (LSA). Each entry in the thesaurus – a word sense along with its synonyms and antonyms – is treated as a “document,” and the resulting document collection is subjected to LSA. The key contribution...
LLM-generated classifications are pushing research into new directions that will ultimately improve user experience and satisfaction when using chat and other user-AI interaction tools. This analysis indicates that Copilot in Bing is enabling users to do more complex work, specificall...

LSA(latent semantic analysis)潜在语义分析,也被称为LSI(latent semantic index),是Scott Deerwester, Susan T. Dumais等人在1990年提出来的一种新的索引和检索方法。该方法和传统向量空间模型(vector space model)一样使用向量来表示词(terms)和文档(documents),并通过向量间的关系(如夹角)来判断词及文档间的关系...
resulting in the examination of a total of 150 predictions, although six ground truth queries were absent from the SPICE dataset and were thus excluded from the analysis. By employing an iterative process involving the creation and consolidation of error categories, we successfully identified eight pr...

5b). Further analysis of cell-type co-occurrence in both BRCA samples revealed a positive correlation between myoepithelial cells and DCIS, but a negative correlation between myoepithelial cells and IDC (Fig. 5c, d). These findings align with previous research that links decreased myoepithelial ...
The approach is to take advantage of implicit higher-order structure in the association of terms with documents (“semantic structure”) in order to improve the detection of relevant documents on the basis of terms found in queries. The particular technique used is singular-value decomposition, in...
Run-time analysis. Two properties make detection efficient. First, all CNN parameters are shared across all categories. Second, the feature vectors computed by the CNN are low-dimensional when compared to other common approaches, such as spatial pyramids with bag-of-visualword encodings. Th...
