Texera is a system to support text analytics as a Web-based service by using declarative GUI-based workflows.
- Many text analysts need to spend a significant amount of effort on low-level computation such as keyword search, regular expressions, dictionary-based matching, and natural language processing (NLP). They can also face the long running time and lack of debugging tools, and need to re-run the program after making just some minor changes.
- At the same time, cloud-based services and technologies have emerged and advanced significantly in the past decade.
- Provide text analytics as cloud services so users do not need to download software and do periodic updates and patches. Plus sharing becomes much easier;
- Provide a browser-based GUI for developers to form a workflow plan declaratively without writing code;
- Allow non-IT people to do text anlytics.
- Increase productivity of text analytics.
The following is a workflow formulated using the Texera GUI in a Web browser. It consists of a workflow of basic operators, such as keyword search, sentiment analysis, and NLP.
