“…Formally, for each sentence s and topic k, we calculate the probability, p s k , of words in s assigned to k, averaged over n samples, and use arg max k p s k as the label for s. 1) Weak Supervision with Minimal Prior Knowledge: To encourage topic models to learn latent topics that correlate directly with aspects, we augment them with a weak supervised signal in the form of aspect-specific seed words. Rather than directly using the seed words to do bootstrapping, as in [19] and [20], we use them to define an asymmetric prior on the word-topic distributions. This approach guides the latent topic learning towards more coherent aspect-specific topics, while also allowing us to utilize large-scale unlabeled data.…”

Abstract-We investigate the efficacy of topic model based approaches to two multi-aspect sentiment analysis tasks: multiaspect sentence labeling and multi-aspect rating prediction. For sentence labeling, we propose a weakly-supervised approach that utilizes only minimal prior knowledge-in the form of seed words-to enforce a direct correspondence between topics and aspects. This correspondence is used to label sentences with performance that approaches a fully supervised baseline. For multi-aspect rating prediction, we find that overall ratings can be used in conjunction with our sentence labelings to achieve reasonable performance compared to a fully supervised baseline. When gold-standard aspect-ratings are available, we find that topic model based features can be used to improve unsophisticated supervised baseline performance, in agreement with previous multi-aspect rating prediction work. This improvement is diminished, however, when topic model features are paired with a more competitive supervised baseline-a finding not acknowledged in previous work.

Finding out the widely used URL's from online shopping sites for any particular category is a difficult task as there are many heterogeneous and multi-dimensional data set which depends on various factors. Traditional data mining methods are limited to homogenous data source, so they fail to sufficiently consider the characteristics of heterogeneous data. This paper presents a consistent Big Data mining search which performs analytics on text data to find the top rated URL's. Though many heuristic search methods are available, our proposed method solves the problem of searching compared with traditional methods in data mining. The sample results are obtained in optimal time and are compared with other methods which is effective and efficient.

Abstrac t-We have tried to examine the viability of topic model based methodologies to two mu lti-aspect sentiment analysis tasks: mult i-aspect sentence labeling and mult iaspect rating prediction. Fo r o ne o f th e t as ks o f sentence labeling, we propose a weakly -superv ised app roach that utilizes only minimal prior knowledge-in the form of seed words-to uphold an immed iate correspondence between topics and aspects. This correspondence will be utilized to name sentences with execution that approaches a fully supervised standard. For multi-aspect rating prediction, we find that general evaluations can be utilized as a part of conjunction with our sentence labeling to accomplish sensible execution contrasted with a fully supervised baseline. At the point when highest level perspective evaluations are accessible, we find that topic model based characteristics can be utilized to enhance unsophisticated supervised pattern execution, in concurrence with past mult i-aspect rating prediction work...
