Languages are heavily influenced by historical and cultural factors. They evolve because of political and social reasons. Because of geographical and commerce related factors, some languages develop numerous dialects over centuries, like Chinese. Some languages are related to each other, making them similar, and yet different, like Russian and Polish. From phonetics, to how words are strung together to form a sentence, the accurate and true semantic meaning in a language cannot be gauged by a semantic technology company, by simply translating them into another language, in most cases, English. Case in point, Mandarin has 22 consonants, while Hawaiin has only 8. German is a Category II language, meaning it's a relatively easy language to gain proficiency in by native English speakers, while Korean is a Category V language, which means that native English speakers need more than 2000 hours to achieve the same proficiency.
Should translations be used for Chinese sentiment analysis?
Chinese differs from English not only phonetically, but also in syntax, word structure and quite simply, vocabulary. When data is directly translated into another language so completely different in etymology, it just cannot give accurate results. The reason being that the language it's being translated into, does not have the vocabulary to match the emotional tone nor the context in which a particular word is used. This is the case for most languages. Which is why this approach of first translating data in one language into English first, to derive semantic understanding, yields terribly inaccurate results. Trying to achieve Chinese sentiment analysis by using an API that uses a translation technique in its algorithm will be of no actual benefit to an organization. That's why Repustate, as a sentiment analysis company, has uniquely developed a sophisticated Chinese sentiment analysis API that extracts meaningful insights from the sea of unstructured data, in the native language itself. Thus giving you a higher accurate representation of the sentiments from the data, and empowering you with a higher degree of focussed, actionable insights.
Conditional Random Fields in Chinese
Unlike English or Latin-based languages, Chinese (simplified) doesn't
necessarily disambiguate words using whitespace. For example the following
string of symbols is a completely normal sentence in Chinese:
(For those who don't read Chinese, this is a review of a restaurant).
Now you'll see a few white spaces here & there but there's actually many
more words being expressed than there are separated tokens. So how do we
know where one word (or idea) begins and the next ends?
We use a technique called conditional random fields which uses
probabilistic models to infer what the meaning of a particular glyph
(character) is given the glyphs around it. With a large enough pre-tagged
corpus of Chinese text, Repustate can achieve almost 100% perfection in
identifying the individual words or ideas being expressed in a long chain
of Chinese glyphs.

What are the Basic Steps in Chinese Sentiment Analysis?
Sentiments are feelings based on an opinion that a person has developed due to their experience of a particular situation or event. When they express this experience in words by uploading a video on Youtube or TikTok, or by writing a review on a website or survey, they are giving tangible proof of their feelings. Chinese part-of-speech tagging allows us to focus on where these sentiments may actually be exactly within a block of text. Verbs, nouns, and adjectives provide the cues necessary to determine sentiment, and aid in detailed analysis.
The first step in Chinese Sentiment Analysis, is to create a fast and accurate Chinese part-of-speech tagger, for which data scientists need to have a massive corpus, or collection of texts, of the manually tagged Chinese text. This text can then be fed into a machine-learning based algorithm to create an Chinese part-of-speech tagger. The larger the corpus, and more importantly, the more varied it is, the better the results in creating the Chinese part-of-speech tagger. Which is why engineers at Repustate have created a massive corpus of Chinese text grabbing data from a variety of sources in order to obtain an all-encompassing coverage of all aspects of business and social interactions.
Further granulating the algorithm for deeper accuracy, Repustate uses Chinese Named Entity Recognition with advanced semantic search for enterprises to identify brand and business entities in data. No matter how misspelled a word is, our API will reproduce the name first in native script and so improve the accuracy of a name search, transliteration, and identity verification measures. This in turn, gives high-accuracy ranked results, on the basis of the linguistic, phonetic, and specific cultural variation patterns of the names.
Chinese Language Sentiment Models
Repustate has developed sentiment language models specific to Chinese to capture the various phrases, idioms, and expressions that help define sentiments. Understanding the various grammatical aspects of the Chinese language that make it unique and very different from English is what allows Repustate's Chinese sentiment analysis to be as fast and as accurate as it is.
