etcML,在线免费文本分析工具

网站:www.etcml.com 在线免费文本分析工具

etcml,工具网站,在线免费文本分析工具,工具,etcML提供了一种简单的方式,对单词和短语所体现的观点进行分类。

我还可以和记者或研究人员分享我的分类器。斯坦福大学计算机科学博士生Chinmay Kulkarni使用etcML对2000名学生的简答题测验进行打分。此前,简答题打分是通过学生之间的互相打分完成的,平局每道题有4个学生进行打分。通过etcML打分后,平局每道题只需要3个或更少的学生打分。

etcML provides easy-to-use access to high-quality machine learning algorithms that can induce meaningful structure from your textual data. Our primary mode of analysis is classification, which you can think of as automatic categorization.

The input data - often referred to as training data - to our system is text, where each piece of text (usually a sentence or a document) has a predefined label. The system learns which labels are statistically associated with which kinds of words, and then can use that information to make accurate predictions about new, unlabeled data.

For example, we used the text of several thousands of online movie reviews as the training data for our sentiment classifier. We treated the star rating assigned to each review as its label, and had the system learn which kinds of words are associated with positive reviews, and which are associated with negative reviews. You can try typing in a positive or negative sentence, and the classifier will make a prediction about how likely it is that your sentence is expressing positive or negative sentiment.etcml,文本分析引擎,智能文本机器人。
