What This Chinese Sentiment Checker Does
Chinese sentiment analysis is harder than English sentiment analysis for one structural reason: written Chinese has no spaces between words. Before any opinion can be measured, the text has to be cut into words — and the same three characters can split two different ways with two different meanings. On top of that, Chinese expresses degree and negation with short particles placed before the word they affect, so 好 (good), 很好 (very good), 不好 (not good) and 不太好 (not very good) all need to land on different points of the scale rather than all counting as one "good".
This tool handles that on the server: it reads the text in Chinese word units rather than loose characters, and weighs every expression of opinion against the intensifiers and negations attached to it. You get a positive share, a negative share, and a single overall score from −100 to +100, along with a confidence level that tells you how strong the underlying signal is — because a verdict drawn from a faint signal deserves far less trust than one drawn from a strong, consistent one.
Why Brand-Level Sentiment Matters
A single overall score is the wrong answer for most real Chinese content. Comparison posts on Zhihu, review round-ups on Xiaohongshu and forum threads on Weibo routinely praise one product and criticise another in the same breath. Averaged together, those cancel out and the document looks neutral — which tells you nothing useful about either brand.
Naming your brands changes the question from "what is the mood of this text?" to "what does this text say about us, and about our competitors?" The tool scores each brand from the sentiment surrounding its own mentions and keeps competing brands from absorbing each other's score when they share a sentence, then lays them out side by side on one scale so the comparison is immediate.
That makes it useful for competitor monitoring, campaign response tracking, review triage before a China market entry, and screening influencer or KOL coverage before you pay for more of it. If you want this running continuously across Chinese social platforms rather than one text at a time, that is what our Chinese social media and Baidu SEO teams build for clients.
How to Use the Chinese Sentiment Analysis Tool
- Add your brands — optional. Write each brand as a bracket group:
(baidu,百度),(huawei,华为). Every spelling inside one group counts as the same brand, so English and Chinese names are tracked together. - Paste your Chinese text — a review, a batch of comments, an article, a transcript. Up to 5,000 characters per run.
- Click "Analyse sentiment" — the overall score appears first, then a card for each brand you named.
- Read the confidence line before the score — it tells you whether the signal was strong enough to trust the number.
- Compare the brands — the table puts every brand on one shared scale, so you can see at a glance which is ahead and by how much.
What It Cannot Do
Being straight about the limits makes the output more useful, not less. It measures how opinion is actually phrased, so it will not catch sarcasm, irony, or criticism implied without any negative phrasing — 这质量真是“感人” reads as positive to automated analysis of any kind. It does not resolve pronouns, so praise in one sentence and 他们 in the next will not be connected to the brand. Very short texts give unstable results, which is why a low-confidence flag appears instead of a confident number.
It is built for Simplified Chinese. Traditional Chinese is analysed and shared vocabulary is recognised, but coverage is lower — convert to Simplified first for anything important. Treat the tool as a fast first pass that tells you which documents deserve a human read, not as a replacement for that read.
Frequently Asked Questions
-
Chinese sentiment analysis is the process of reading a piece of Chinese text and measuring whether the opinions expressed in it are positive, negative or neutral. It is used to monitor product reviews, social media comments, customer feedback and press coverage at a scale no team could read manually. Chinese needs a different approach from English because there are no spaces between words (分词), so the text must first be split into words before any opinion can be measured.
-
It analyses how opinion is expressed in the text, accounting for negation and intensity, so 不好 (not good) and 非常好 (very good) land on different points of the scale rather than both counting the same way. On clearly worded review and social copy it agrees with human judgement most of the time. It cannot reliably detect sarcasm, irony or criticism implied without any negative phrasing, and it reports a confidence level with every result so you can see how strong the signal behind the score is. Treat it as a fast first pass rather than a final verdict.
-
Overall sentiment tells you the mood of a whole document. Brand-level sentiment tells you how a specific company or product is spoken about inside that document. This matters when one text mentions several brands: a comparison article can be positive about one product and negative about another, and a single overall figure would average the two into something meaningless. This tool scores each brand you name separately, using only the sentiment found near that brand's mentions.
-
Put each brand in round brackets, and list every spelling that should identify it, separated by commas. For example (baidu,百度),(huawei,华为) tracks two brands, each recognised by either its English or its Chinese name. Grouping the spellings matters: it means a text that writes Huawei in English in one sentence and 华为 in Chinese in the next is still counted as one brand. The field is optional — leave it empty for overall sentiment only.
-
It is built primarily for Simplified Chinese, which covers mainland China, Baidu, WeChat, Weibo and Xiaohongshu. Traditional Chinese text from Taiwan, Hong Kong and Macau will still be analysed and shared vocabulary will be recognised, but coverage is lower, so expect fewer matches and a lower reported confidence. For serious Traditional Chinese work, convert the text to Simplified first.
-
Up to 5,000 Chinese characters per analysis, which is roughly a long article or several hundred short reviews or comments. Anything beyond that is trimmed and the tool tells you it was trimmed. For batch work across thousands of documents, the same analysis can be run as a service on your own data — get in touch if that is what you need.

No. The text is analysed during the request and the result is returned in the same page load. It is not written to a database, not logged and not used for training. Nothing is retained after the response is sent — see our privacy policy for details.
