Statistics and linguistics combined to provide more accurate sentiment analysis results
Provides a choice of approaches to sentiment analysis:
Statistical modeling: Provides predefined default parameters – that can also be configured – to identify the document sentiment from text.
Linguistic rules: Lets subject-matter experts define the elements to be examined for sentiment assessment.
Hybrid approach: Provides the unique ability to use both statistical rigor and linguistic metrics to define sentiment models driving more detailed sentiment evaluations.
Ability to import and/or create concepts for evaluations.
Extended sentiment evaluation
Specify as "unclassified" any terms in a taxonomy that are found in the text but are not identified as positive, negative or neutral. This capability provides two main benefits:
Assists with model refinement.
Helps refine activity by pointing out unemotional statements.
Context of features examined for accurate interpretations
Supports complex linguistic metrics for one or several matches of a term, regular expressions, part-of-speech tags, the distance or occurrence of concepts in relation to other words, and more.
Includes prebuilt tasks to simplify linguistic pattern identification. It offers:
Predicate rules to define semantic relationships between concepts.
Operators to locate related information with greater precision, such as co-referencing.
Identification of intermediate concepts that contain rules referenced by other concepts (shortens the rule-writing process).
Case-insensitive matching, so you can match both uppercase and lowercase terms.
Dynamic sentiment analysis
Permits improvements and/or changes over time with multiple model generation within the same project, and the ability to edit and test model modifications.
Allows subject matter experts to refine model performance with an easy-to-use point-and-click workbench.
Monitoring of results over time will inform model analysis refinement, and comparisons to benchmark training sets can be established to allow for continuous improvement.
Sentiment terms can be industry specific. For example, analysis of public sentiment about a feature film will differ from analysis of sentiment on political candidates. USAP provides custom linguistic analysis including geotargeting.
Easy-to-use interface for model development
A mechanism to directly upload sentiment analysis models to the server reduces manual model deployment.
Keyboard shortcuts are available for interactivity, as well as enhanced search functionality assisting with model development activity.
Project wizard allows you to configure your project while it is being defined.
Panes in the interface simplify tasks and display more information, such as rule evaluations and search results.
Interactive workbench for model refinement
Graphics depicting sentiment are displayed to readily identify the resulting classification as positive, negative, neutral or unclassified.
Point-and-click exploration of classified text, drilling to detail as desired.
Enhanced report formatting improves results display.
Ability to add new concepts/entities to capture desired topics.
Word cloud report, based on defined concepts, automatically illustrates extracted noun phrases.
Some workbench functionality is available through Web services APIs so documents can be programmatically added to different projects, exported, managed, searched, etc.
Updates on Web postings, reviews and opinions
High-performance, multithreaded crawler that can be deployed in a distributed mode to maximize processing and support extremely large-scale crawls for both internal file system and Internet crawls.
Powerful linguistic technology is built in to extract URLs from Java scripts.
Web crawls can be interrupted and resumed.
Document processor makes it easy to parse, export and control processing and output.
Duplications are automatically removed.
Supports desired restrictions (e.g., to specific file formats or servers, restrict the area or specify search depth) on crawling to customize searches.
Multiple languages supported
A mobile platform is available, providing up to the moment trending topics around the world on a Smartphone.
Full suite of 27 languages (plus dialects) available.
Supports Arabic, Chinese (both Simplified and Traditional), Czech, Danish, Dutch, English (US/UK), Finnish, French (French/Canadian), German (New/Old), Greek, Hebrew, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian (Nynorsk/Bokmål), Polish, Portuguese (Portugal/Brazil), Romanian, Russian, Slovak, Spanish (Spain/South America), Swedish, Thai, Turkish and Vietnamese.
