Reel Two offers range of powerful tools for text search and analysis. SureChem enables users to quickly identify all the chemical compounds in text documents, such as patents or journal abstracts. Classification System is a versatile application allowing rapid, custom categorization of text files or documents in either desktop or enterprise configurations. The Entity Extractor is a software development kit that lets users implement their own systems of identifying, tagging and marking up documents for specific types of terms, such as people, place names and company names. This can be combined with Classification System for a powerful search and analysis system.

Data Sets

Reel Two is constantly engaged in developing new datasets that test the performance and robustness of the Classification System technology. The sample datasets included here are from a variety of applications in different industries, and demonstrate the Classification System's ability to work with both text and nominal data formats.

The table lists statistics for each dataset, including "Build Time" and "F-Measure". Build Time is the time to load, model and evaluate (using Leave-One-Out evaluation) a dataset on a WinXP/1GHz Celeron/256MB computer. F-Measure is the micro-averaged F-Measure across all categories in the dataset.

Categories Instances Build Time F Measure
Reuters-21578 (Top 10)

The Reuters News research dataset is a compilation of new stories from Reuters News organized into a number of topics. Identifying the documents from the largest 10 categories is one of the most popular text categorization tests.
