Abstract: Methods, systems, and non-transitory media for training a chemical entity recognition system to extract chemical compounds from a patent document and determine a relevance of the chemical compounds to the patent document are disclosed. A method includes obtaining patent documents from patent databases, normalizing each patent document into a unified format, and generating a chemical patent corpus. The chemical patent corpus includes chemical entities, each having relevancy annotations that indicate a relevance to the patent document from which the chemical entity is extracted.

Abstract: The invention refers to a method of creating, storing and retrieving data sets including many complex data elements comprising the steps of receiving multiple data elements to be stored from an input data structure, providing a transformed and normalized data structure for storage into an inverted index and storage data system and providing a inverted index based search engine that allows to retrieve those data elements using hierarchical and relational data queries. In particular, the invention refers to a method for providing an interface to an inverted index and storage by creating algorithmically a logical index schema and view from the structure of the received data elements, including hierarchical and other relational information. Moreover, the present invention also refers to a method for searching those hierarchical and relational searching data structures.
