You need to search for numeric ranges, temperatures, dosages and other quantities within technical documents? quantalyze provides you with a powerful online service to identify, normalize and semantically annotate quantities in text. With the quantalyze workbench you will retrieve the most relevant documents in the fastest possible way.

quantalyze provides a Web-based service that gives you the possibility to retrieve technical documents such as patents containing specific quantities, intervals and/or units of measurement. You can perform searches independently of the unit system and the language used in the documents. quantalyze seamlessly combines these features with state-of-the-art full-text search and filtering.

The quantalyze backend technology

  • detects quantity expressions (e.g. 0.4, seven million) and units of measure (e.g. degrees Celsius, kilogram, inches etc.) in documents.
  • identifies intervals such as "70°C to about 80°C" and will retrieve relevant documents if a query includes a temperature within this interval.
  • automatically converts measurement values into a standard unit of measure enabling transparent searching across unit systems.
  • performs multilingual indexing of quantities enabling transparent searching across different languages.

To take advantage of the functionalities of quantalyze, you do not need to download or install any software on your computer.

Relying on quantalyze reduces the duration of your search process and maximizes the amount of relevant documents found. Thus, it increases the reliability of your recommendations (decisions), because they are grounded on a far more comprehensive and relevant set of information.
