Lexalytics Unveils Sentiment Analysis of Emoticons, Acronyms for Twitter
Lexalytics, Inc., a software and services company specializing in text and sentiment analysis, announced the availability of richer reporting on the conversations occurring around, about, and between different accounts on Twitter based on the sentiment analysis of commonly used emoticons and acronyms. The company claims to have the first OEM engine to examine short form content for sentiment analysis.
With the use of emoticons, abbreviations, and confusing “social speak” grammar, micro-blog services such as Twitter present a difficult task for natural language processing systems. These improvements come as part of the yearly software license for Salience, Lexalytics’ core text analytics engine.
For acronyms, the Lexalytics team parsed thousands of tweets to get to hundreds of common acronyms and emoticons. The team then made decisions on whether each acronym was sentiment-bearing, needed to be expanded, or should be treated as simply an interjection.
For the @ sign, Salience part-of-speech tags the @ tagged string as a “MENTION” which can be used for further reporting. In particular, @ tagged strings will return as people entities, with the associated sentiment, themes, etc. Additionally, # sign (hashtags) are part-of-speech tagged as @hashtag. These do not report back as any sort of entity type. Hashtags are typically used as a lightweight “tag” for the content of the tweet. This information can be used by Salience for further processing as a tag.
Check out the new capabilities at www.lexalytics.com/demo. Select the “Twitter” radio button. Paste a tweet in and test out what Lexalytics returns.
Lexalytics’ out-of-the-box, business critical text analytics and sentiment solutions allows companies to monitor and react in real-time by making sense of the vast repositories of information from sources as diverse as Twitter, blogs, RSS feeds, websites, and in-house content. Lexalytics solutions include entity extraction, theme discovery, and sentiment analysis at the entity-level.
